Befriending Utility Monsters: Being the Adult in the Room When Talking About the Hedonic Extremes (link)

In this episode I connect a broad variety of topics with the following common thread: “What does it mean to be the adult in the room when dealing with extremely valenced states of consciousness?” Essentially, a talk on Utility Monsters.

Concretely, what does it mean to be responsible and sensible when confronted with the fact that pain and pleasure follow a long tail distribution? When discussing ultra-painful or ultra-blissful experiences one needs to take off the glasses we use to reason about “room temperature consciousness” and put on glasses that actually take these states with the seriousness they deserve.

Topics discussed include: The partial 5HT3 antagonism of ginger juice, kidney stones from vitamin C supplementation, 2C-E nausea, phenibut withdrawal, akathisia as a remarkably common side effect of psychiatric medication (neuroleptics, benzos, and SSRIs), negative 5-MeO-DMT trips, the book “LSD and the Mind of the Universe”, turbulence and laminar flow in the “energy body”, being a “mom” at a festival, and more.

What is Time? Explaining Time-Loops, Moments of Eternity, Time Branching, Time Reversal, and More… (link)

What is (phenomenal) time?

The feeling of time passing is not the same as physical time.

Albert Einstein discovered that “Newtonian time” was a special case of physical time, since gravity, relativity, and the constancy of the speed of light entails that space, time, mass, and gravity are intimately connected. He, in a sense, discovered a generalization of our common-sense notion of physical time; a generalization which accounts for the effects of moving and accelerating frames of reference on the relative passage of time between observers. Physical time, it turns out, could manifest in many more (exotic) ways than was previously thought.

Likewise, we find that our everyday phenomenal time (i.e. the feeling of time passing) is a special case of a far more general set of possible time-like qualities of experience. In particular, in this video I discuss “exotic phenomenal time” experiences, which include oddities such as time-loops, moments of eternity, time branching, and time reversal. I then go on to explain these exotic phenomenal time experiences with a model we call the “pseudo-time arrow”, which involves implicit causality in the network of sensations we experience on each “moment of experience”. Thus we realize that phenomenal time is an incredibly general property! It turns out that we haven’t even scratched the surface of what’s possible here… it’s about time we do so.

Benzos: Why the Withdrawal is Worse than the High is Good (+ Flumazenil/NAD+ Anti-Tolerance Action) (link)

Most people have low-resolution models of how drug tolerance works. Folk theories that “what goes up must come down” and theories in the medical establishment about how you can “stabilize a patient on a dose” and expect optimal effects long term get in the way of actually looking at how tolerance works.

In this video I explain why benzo withdrawal is far worse than the high they give you is good.

Core arguments presented:

  1. Benzos can treat anxiety, insomnia, palpitations, seizures, hallucinations, etc. If you use them to treat one of these symptoms, the rebound will nonetheless involve all of them.
  2. Kindling – How long-term use leads to neural annealing of the “withdrawal neural patterns”.
  3. Amnesia effects prevent you from remembering the good parts/only remembering the bad parts.
  4. Neurotoxicity from long-term benzo use makes it harder for your brain to heal.
  5. Arousal as a multiplier of consciousness: on benzos the “high” is low arousal and the withdrawal is high arousal (compared to stimulants where you at least will “sleep through the withdrawal”).
  6. Tolerance still builds up even when you don’t have a “psychoactive dose” in your body – meaning that the extremely long half-life of clonazepam and diazepam and their metabolites (50h+) entails that you still develop long-term tolerance even with weekly or biweekly use!

I then go into how the (empirically false) common-sense view of drug tolerance is delaying promising research avenues, such as “anti-tolerance drugs” (see links below). In particular, NAD+ IV and Flumazenil seem to have large effect sizes for treating benzo withdrawals. I AM NOT CONFIDENT THAT THEY WORK, but I think it is silly to not look into them with our best science at this point. Clinical trials for NAD+ IV therapy for drug withdrawal are underway, and the research to date on flumazenil seems extremely promising. Please let me know if you have any experience using either of these two tools and whether you had success with them or not.

Note: These treatments may also generalize to other GABAergic drugs like gabapentin, alcohol, and phenibut (which also have horrible withdrawals, but are far shorter than benzo withdrawal).

Further readings:

Epileptic patients who have become tolerant to the anti-seizure effects of the benzodiazepine clonazepam became seizure-free for several days after treatment with 1.5 mg of flumazenil.[14] Similarly, patients who were dependent on high doses of benzodiazepines […] were able to be stabilised on a low dose of clonazepam after 7–8 days of treatment with flumazenil.[15]”

Flumazenil has been tested against placebo in benzo-dependent subjects. Results showed that typical benzodiazepine withdrawal effects were reversed with few to no symptoms.[16] Flumazenil was also shown to produce significantly fewer withdrawal symptoms than saline in a randomized, placebo-controlled study with benzodiazepine-dependent subjects. Additionally, relapse rates were much lower during subsequent follow-up.[17]

Scale-Specific Network Geometry (link)

Is it possible for the “natural growth” of a pandemic to be slower than exponential no matter where it starts? What are ways in which we can leverage the graphical properties of the “contact network” of humanity in order to control contagious diseases? In this video I offer a novel way of analyzing and designing networks that may allow us to easily prevent the exponential growth of future pandemics.

Topics covered: The difference between the aesthetic of pure math vs. applied statistics when it comes to making sense of graphs. Applications of graph analysis. Identifying people with a high centrality in social networks. Klout scores. Graphlets. Kinds of graphs: geometric, small world, scale-free, empirical (galactic core + “whiskers”). Pandemics being difficult to control due to exponential growth. Using a sort of “pandemic Klout score” to prioritize who to quarantine, who to vaccinate first. The network properties that made the plague spread so slowly in the Middle Ages. Toroidal planets as having linear pandemic growth after a certain threshold number of infections. Non-integer graph dimensionality. Dimensional chokes. And… kitchen sponges.

Readings either referenced in the video or useful to learn more about this topic:

Leskovec’s paper (the last link above):

Main Empirical Findings: Our results suggest a rather detailed and somewhat counterintuitive picture of the community structure in large networks. Several qualitative properties of community structure are nearly universal:

• Up to a size scale, which empirically is roughly 100 nodes, there not only exist well-separated communities, but also the slope of the network community profile plot is generally sloping downward. (See Fig. 1(a).) This latter point suggests, and empirically we often observe, that smaller communities can be combined into meaningful larger communities.

• At size scale of 100 nodes, we often observe the global minimum of the network community profile plot. (Although these are the “best” communities in the entire graph, they are usually connected to the remainder of the network by just a single edge.)

• Above the size scale of roughly 100 nodes, the network community profile plot gradually increases, and thus there is a nearly inverse relationship between community size and community quality. This upward slope suggests, and empirically we often observe, that as a function of increasing size, the best possible communities as they grow become more and more “blended into” the remainder of the network.

We have also examined in detail the structure of our social and information networks. We have observed that an ‘jellyfish’ or ‘octopus’ model [33, 7] provides a rough first approximation to structure of many of the networks we have examined.

Ps. Forgot to explain the sponge’s relevance: the scale-specific network geometry of a sponge is roughly hyperbolic at a small scale. Then the material is cubic at medium scale. And at the scale where you look at it as flat (being a sheet with finite thickness) it is two dimensional.

Why Does DMT Feel So Real? Multi-modal Coherence, High Temperature Parameter, Tactile Hallucinations (link)

Why does DMT feel so “real”? Why does it feel like you experience genuine mind-independent realities on DMT?

In this video I explain that we all implicitly rely on a model of which signals are trustworthy and which ones are not. In particular, in order to avoid losing one’s mind during an intense exotic experience (such as those catalyzed by psychedelics, dissociatives, or meditation) one needs to (a) know that you are altered, (b) have a good model of what that alteration entails, and (c) that the alteration is not strong enough that it breaks down either (a) or (b). So drugs that make you forget you are under the influence, or that you don’t know how to model (or have a mistaken model of) can deeply disrupt your “web of trusted beliefs”.

I argue that one cannot really import the models that one learned from other psychedelics about “what psychedelics do” to DMT; DMT alters you in a far broader way. For example, most people on LSD may mistrust what they see, but they will not mistrust what they touch (touch stays a “trusted signal” on LSD). But on DMT you can experience tactile hallucinations that are coherent with one’s visions! “Crossing the veil” on DMT is not a visual experience: it’s a multi-modal experience, like entering a cave hiding behind a waterfall.

Some of the signals that DMT messes with that often convince people that what they experienced was mind-independent include:

  1. Hyperbolic geometry and mathematical complexity; experiencing “impossible objects”.
  2. Incredibly high-resolution multi-modal integration: hallucinations are “coherent” across senses.
  3. Philosophical qualia enhancement: it alters not only your senses and emotions, but also “the way you organize models of reality”.
  4. More “energized” experiences feel inherently more real, and DMT can increase the energy parameter to an extreme degree.
  5. Highly valenced experiences also feel more real – the bliss and the horror are interpreted as “belonging to the vibe of a reality” rather than being just a property of your experience.
  6. DMT can give you powerful hallucinations in every modality: not only visual hallucinations, but also tactile, auditory, scent, taste, and proprioception.
  7. Novel and exotic feelings of “electromagnetism”.
  8. Sense of “wisdom”.
  9. Knowledge of your feelings: the entities know more about you than you yourself know about yourself.

With all of these signals being liable to chaotic alterations on DMT it makes sense that even very bright and rational people may experience a “shift” in their beliefs about reality. The trusted signals will have altered their consilience point. And since each point of consilience between trusted signals entails a worldview, people who believe in the independent reality of the realms disclosed by DMT share trust in some signals most people don’t even know exist. We can expect some pushback for this analysis by people who trust any of the signals altered by DMT listed above. Which is fine! But… if we want to create a rational Super-Shulgin Academy to really make some serious progress in mapping-out the state-space of consciousness, we will need to prevent epistemological mishaps. I.e. We have to model insanity so that we ourselves can stay sane.

The Symmetry Theory of Valence: 2020 Presentation

Presentation Given at the Centre for Psychedelic Research at Imperial College London by Andrés Gómez Emilsson (December 8th 2020)


Transcribed with otter.ai. Edited for grammar and clarity by Mackenzie Dion.

Watch the talk on our Youtube channel.

So, the Symmetry Theory of Valence. Just defining terms so that we’re all on the same page. There’s this thing called core affect which is basically what you get when you apply dimensionality reduction techniques to any one of many areas of psychology. There’s a surprisingly robust pair of dimensions that emerge in co-occurrences of words or even descriptions of behavior. These two axes, arousal and valence, seem to account for about 60% of the variance in terms of what information emotional words contain. And I mean, roughly speaking, arousal is the level of activation, how energetic you are, and valence is how good you feel. Most of what I’m going to be talking about is valence. That said, you need to also consider arousal in the picture to know what this is all about. Just a few examples: you have high arousal, high valence, so that would be kind of excitement and anticipation. But you also can have high energy, but not feeling really good, and that would be kind of anxiety or anger or irritation. Likewise, you have depression, which is low arousal, low valence, and serenity is peaceful, blissful calm, that would be low arousal, high valence. 

This is just one example of one of the ways in which you can recover these dimensions of valence and arousal. This was a little study we conducted years ago. We were studying people who have experiences with all kinds of substances online. We were giving them the survey, where they were going to describe a particular substance along something like 70 different dimensions. Then I conducted factor analysis on that data set. Interestingly, we have three core dimensions of valence or valence-related axes, which give you a sense of, okay, what is the space of possible effects that you can get from some substances. There were actually six dimensions that emerged, but three of them are valence-related:

We have slow euphoria, which is equivalent to low arousal, high valence with top terms like calming and relieving. The negative predictors of it would be something like anxiety, producing difficult bodily discomfort. Fast euphoria is the sort of thing you get with stimulants, you know, energizing, sociable, the opposite of feeling spaced out and confused.

The other axis that kind of emerged was this notion of spiritual euphoria. That’s the term I used back then. I also used the term significance, or saliency nowadays. Now I would actually use the term criticality for other reasons that we can go into. There’s this other kind of axis for how you can experience intense valence with substances, which is different from slow and fast euphoria, which would roughly correspond to the psychedelic space. And that, you know, gets marked with things such as mystical, incredible, life changing. The opposite of that is trivial, self-centered, or irrelevant or something like that. This is just to complete the cube. And, you know, in a sense…

This is just a kind of change of basis, where you still get, in a sense, the valence dimension emerging out of this dimensionality reduction analysis. If you were to apply just one dimension, you know, if you ask the factor analysis to just give you one factor, it is going to be the valence factor. That’s the axis that accounts for most of the variance for the effects of drugs.

I’ve got to say that I absolutely acknowledge that emotions are far more complex and intricate than just valence and arousal. This is the result of my master’s thesis where we were analyzing this thing called mood updates, how people feel over time, day after day. I was computing the transition probabilities between emotions, and you can do cluster analysis here and finding attractors. You’ll see that there’s additional information. That said, we concluded that a big chunk of the additional information that is not valence and arousal is actually information about your trajectory in the valence arousal space. For example, we found there would be emotions that because of what they tell you about your emotional dynamics we called gateway emotions, like feeling relieved and feeling hopeful. These terms contain information that you were in a negative, kind of depressive attractor, and you’re moving towards the positive high arousal attractor. In essence, the terms we use for emotions give you not only information about where you are in the valence-arousal space but also what is your trajectory in that space. But in a sense, valence and arousal still account for a very, very big chunk of what an emotion is. Okay, so hopefully I’ve convinced you of the importance of valence, at least in this context.

Now, let’s jump into the Symmetry Theory of Valence (STV). The overall hypotheses and the first explicit argument for it appeared in this really, really awesome work by my collaborator, Michael Johnson, Principia Qualia. He has a really interesting skeleton of an argument that points to a lot of research threads that are really worth getting into. I highly recommend digging into this work.

One of the things that it lays out is the kind of conceptual framework to make sense of what type of thing valence might be. I’ll just define a couple terms, which is, first qualia formalism. If there’s one thing at QRI we are married to, you could say, it would be qualia formalism. That is, for any conscious experience, there exists a mathematical object isomorphic to it. We can make an analogy here to something like electromagnetism where we used to have lightning, and electricity, and magnets, and all of that seemed sort of somehow thinly related. But, it turns out that there’s actually just four equations of electromagnetism that tie together all of that phenomena. And you can compare it to something like élan vital, the essence of life. People used to think that maybe there is some kind of a substance that determines whether you’re alive or not. And we would say that, well, that kind of fell through, you know, in the end there is molecular complexity under more molecular complexity. There doesn’t seem to be such a thing as “life itself”. Life is not formalizable in the same way as electromagnetism is, but something that we would claim at QRI or we could even say something that we assume at QRI, because we believe it is a very generative frame, is that yes, there will be a set of deep mathematical structures to consciousness. In particular, if you expand this into other areas, we also think this is going to apply to valence: that there is going to be a deep and rich mathematical structure to valence, and that notion is called valence structuralism.

In Principia Qualia by Mike Johnson, he has this argument for it, which I definitely recommend reading, especially if you have the aesthetic of a physicist. I think you’ll really like this work, because I think it’s really, really good in that sense. What I’m going to do now is try to give you a kind of intuition for it. And then the whole empirical argument.

Importantly, there are a lot of theories of what valence is. Mike looked at the literature, did a very deep dive into it, and realized that they’re usually unsatisfactory, or at the very least, they don’t get at the true core of what an explanation for valence should be like. So basically, you have these accounts of, for example, valence sees how the brain represents value. Ultimately, that’s just a correlation. Value is a fuzzy abstraction. Some people think valence is the presence of opioids in the brain. But if you inject opioids in different parts of the brain, it doesn’t always feel good. It actually needs to be injected in a very narrow range of stripes in the pleasure centers, and otherwise, it just causes strange feelings or wanting, but it’s not the signature of valence itself. Or, for example, the pleasure centers. Just because you’re calling something “the pleasure center”, and it’s correlated with feeling good, it doesn’t mean you have an explanation. It’s not a very insightful, illuminating, account of valence. 

So what could it be? I’ll focus to a large extent on what we are going to call bliss, which is just very positive valence. What is that? What is very positive valence? What is the sense of ecstasy, bliss, intense happiness? There’s a lot of intuitions. Definitely a lot of people think it’s some kind of spiritual signal, and I wouldn’t want to convince you out of that view. But the truth is that there are a lot of different spiritualities, and they sometimes say contradictory things. So it’s kind of strange to expect that there’s this underlying universal spiritual signal that whenever you’re doing something aligned with spirit, you feel good. Because sometimes you can do something very different than somebody else and still have that feeling. Also, the idea that it is “merely” chemical reactions in the brain, again, is not a super satisfactory explanation… same as with pleasure centers, health, few prediction errors, etc. Well, and in the end, I add, yes, symmetry and consciousness, which is what I will be arguing.

I also want to point out, and this is super important, that valence is not the same as healing, and it’s not the same as meaning. However, they’re correlated. I would also go as far as to say that high valence is necessary for healing and for meaning to a large extent. In a sense, you can have a lot of very high valence states that are actually very unhealthy for you. Just an example would be methamphetamine. It can feel great, but it’s unsustainable. To the extent that your nervous system is self-organizing around that high valence experience, it makes it kind of the center of your life. And, you know, it’s a dopamine releaser. It’s obviously unsustainable. You can’t actually do that long-term and expect good results. Whereas, something like meditation, or even psychedelics, because their tolerance mechanism is very, very different. You could say that, yeah, those might be high valence, highly meaningful, and also healing experiences.

So I just want to say that, you know, high valence doesn’t entail healing. And that in that sense, you might say, “Okay, why are we so interested in this?”, but I would say that high valence is a necessary condition for deep healing. And I would even go as far as to say that, for a psychedelic experience to be deeply healing, it has to involve high valence in one context or another. Of course, you may end up processing a lot of very difficult emotions. But ideally, it would be something that basically allows you to heal those difficult emotions and transform them into a state of mind that has many more of the positive qualities. 

And more so, high valence, even according to the Buddha, is an important factor for awakening. Of the seven factors for awakening, I would actually say about five of them are very connected to valence. Mindfulness, joy, relaxation, concentration, equanimity; they are kind of different flavors of high valence. They’re different ways in which a very high valence experience can manifest. The Buddha says that these are important things. Even if you only care about awakening, enlightenment, you may also care about the mathematics of valence. It might point you in the right direction as well.

I’ll also mention, there’s a big difference between the recipe of a state of consciousness and what you might call the review, or the description, of that state of consciousness. I’ll make an analogy with cooking: if you have cooking instructions for how to make a cake, sometimes it’s very counterintuitive what the cake is going to taste based on those instructions. Like “add yeast” for example. A lot of things in the recipe you may not know exactly how are going to actually affect the result. So, the recipe may look very different from the review of the state. I would say that for a lot of meditation states, or even just general life advice, this idea of don’t mindlessly chasing pleasure or trying to satisfy all of your existing desires compulsively gives counter-intuitive results. Yeah, chasing pleasure compulsively is not going to result in a sustainable high valence. To some extent, a lot of meditation instructions tell you to neither approach nor withdraw from emotions to develop equanimity. Since you are not engaging with your emotions, it sounds like the result is a fully neutral experience, right? It sounds like it’s unrelated to valence, almost cutting out the valence. But I would say: that’s just the recipe. Those are the instructions for how you manage your attention in order to eventually change your brain to actually generate these very healthy, sustainable, high valence states. So I definitely want to overcome this prejudice of thinking that high valence is unrelated to spirituality. No, I think they’re actually very deeply, intimately connected. 

Okay, so let’s go into the Symmetry Theory of Valence. I’ll just read these, but we will go into more depth into all of these. So, you know, we talked about qualia formalism, there is a mathematical object whose features are isomorphic to phenomenology. We believe that, yeah, harmony basically feels good because it’s symmetry over time. And basically, there’s kind of this duality between symmetry and space and synchrony in time. We will go over pleasure centers. The way we explain pleasure centers in this theory is that they are kind of tuning knobs (this was first proposed in Principia Qualia). They are there these bridges that, basically, when they get activated, they enable global large-scale synchrony in the brain. This is something that ultimately is very testable. Because if you can activate the pleasure centers, or inhibit whole brain harmony, we predict that’s going to actually negate the positive valence effects of the pleasure centers. Likewise, if we can induce large scale harmony, without activating the pleasure centers, or maybe even inhibiting the pleasure centers, we expect that to be a high valence state. So, it’s a cool, testable interpretation of what pleasure centers even are. 

Boredom is kind of an anti symmetry mechanism. So that’s why even if you look at a cathedral or something like that, you’re not going to be happy forever. You’re going to be happy for a little bit. Because your brain realizes that you’re not learning anything, and adds kind of this dissonance in order to make you move on to something else. We are wired in such a way that what helps us reproduce symmetrifies our consciousness. So, it’s not that high calorie food in and of itself is symmetrical, it’s not that it in and of itself is pleasant. It’s more that the way our nervous system is programmed is such that when you eat high calorie food, it triggers high valence. And that triggered high valence is what would be symmetrical, not necessarily the chemicals that you’re eating.

Importantly, valence, we think, has these three dimensions, which is positive, neutral, and negative. And you can actually have highly mixed experiences. You can have experiences, I don’t know, an example is you’re at a concert, enjoying yourself, but also you have to go to the bathroom, and you just broke up with your boyfriend. You can have these very complex mixed valence experiences, where parts of your experience are very pleasant, parts are very distressing, parts of those are very neutral, and that’s fine. At the same time, it still kind of collapses into this ultimately, “Hey, are you having a good time or not?”.

And something that the Symmetry Theory of Valence would say, and this is a pretty interesting kind of relationship, and I’ll explain it in a couple slides. This is just to kind of put it out there in your head to bounce around as we go on, which is that we expect there to be a very, very intimate relationship between information content, and basically the range of valence that you have access to. So in brief, for very, very high valence states of consciousness, we expect those to have very close to zero information. Whereas, when you have this state that is close to pure white noise, we expect that to be basically zero valence. Hopefully, this will make more sense as we go along.

These are just some illustrations of this principle. Actually, we expect that some of the most negative experiences out there will actually be pretty close to very, very highly symmetrical. I put this disjointed lattice at the bottom. And I would claim that something like a bad 5-MeO-DMT experience is actually something that is very regular, except for some strange disjoints, or imperfections, that cause profound dissonance. Whereas, if you’re in the pure noise kind of range, it all feels blah, it all feels really close to neutral.

When we say the state of consciousness is highly symmetrical and such, you know, let’s say, 5-MeO-DMT, or jhanas, or something like that, we expect these to actually show up in many ways. If you look at the biorhythms, like heart rate and breathing, that’s going to show up, symmetry is going to show up in some ways, being a different kind of projection of the latent state. I mean, ultimately, the formalism, you know, this mathematical object corresponds to consciousness is not observable directly, at least not right now. So we have to kind of rely on these projections, these interpretations of what’s going on, these ways of getting at this unobservable, underlying state. And EEG, connectome harmonics, biorhythms, and so on, are different ways of getting at it. I’ll show you at least empirically that it’s all so far consistent with the Symmetry Theory of Valence.

Here’s kind of the big plan. All of these different projections of this underlying state. So we have basically this stimulus. These are kind of visualized also to give you an intuition. So there’s stimuli, basically more symmetrical stimuli with higher valence, then there’s the endogenous bodily state, you know, biorhythms, as well. The CNS State, the actual, okay, what’s going on in your brain, then the formalism, and then the phenomenology of valence. When you have high valence, we expect (and what we see is) that there’s symmetry all across the board, in each of these different ways of looking at the state of consciousness. In each of these projections of the latent state.

So I’ll go on and start with phenomenology. I know that phenomenology is such a tricky thing. It’s so difficult to do, right. It’s so difficult to do. You make a lot of mistakes in phenomenology, get confused, and become self-deceived. So I mean, hopefully, the observation I’ll relate to you is going to show you that at least we’re taking care of some of the failure modes of phenomenology.

So, first of all, we distinguish between intentional content and phenomenal character. So, if you smoke DMT, and you experience, you know, you say something like “I saw a dragon with my own eyes” that doesn’t mean there was actually a mind-independent dragon out there. And, you know, I take seriously your report that you saw a dragon, but I don’t know how significant that is necessarily. On the other hand, if you describe “Oh, and by the way, the dragon had scales that had a symmetry group of what’s called the glide mirror symmetry group, and it had a 17 hertz strobing effect“. Okay, yes, so we’re getting more into the phenomenal character. You’re actually describing what it felt like, not only what it was about. I would make the claim that these observations of symmetry being related to valence are about the phenomenal character. I don’t care that much about, you know, “What was the journey? What was the content of the experience?” I care more about what it felt like, what are the features of it, and what we observe is that there’s a deep connection here.

So I’ll just give you some examples. Basically, introspect. You know, the difference between massage and bodily pain. Massage is kind of this very, very pleasant, harmonious, tactile pattern throughout your body that gives you these very nice waves of pleasure, as opposed to bodily pain. Bodily pain, if you introspect on it, it’s almost kind of like there’s like pinch points and discontinuities and fragmentations and deformations in your sense of self and the continuity of your skin or your felt sense of your inner organs. Basically, I would make the claim that bodily pain always manifests in one way or another as a kind of symmetry breaking operation. Now, definitely keep this in mind if you ever have a pain again, hopefully not.

Also, let’s say anxiety versus relaxation. Anxiety, you could almost describe it as, constant prediction errors. “Oh, did my heart do something strange? Is my leg positioned properly?”. It’s a state of mind where all of these little imperfections bubble up to your awareness. I would say it’s interrupting the flow of your attention and creating these pinch points and deformations in the way you experience the world. As opposed to relaxation, where you’re almost kind of just completely melted into it. And it’s so regular, you can almost filter out most of your bodily sensations. And in that sense I would argue it has a very symmetrical quality.

There’s also this whole argument Mike brings up which is the phenomenology concerning non-adaptiveness, the non-adaptiveness principle, which is that basically, there’s a bunch of things out there that feel really good, but that weren’t in our evolutionary environment. Those are hints; we consider those hints that hey, if something wasn’t in the African savanna but feels great, it probably means that it’s kind of directly hacking into the patterns of valence somehow. We didn’t evolve to filter those out or to not get absorbed by them. And yeah, here are some examples, but I’ll go deeper into those. 

Now, there’s also this exotic valence. Bodily pain, anxiety, relaxations: those would be examples of “normal valence”. It’s the valence that we’re all used to. But I would say that also in “strange valences”, like valences in weird states of consciousness, they also follow this pattern. That in some sense, symmetry explains their pleasantness. And I’ll give you some examples.

So, dream music. I’ve had the pleasure or displeasure, you could say, of having had a lot of sleep paralysis and lucid dreams, and this effect is something you can experience in either sleep paralysis or lucid dreams. If you’ve had a lucid dream, where you were making music, or you heard, you’re hallucinating that there was a radio playing, you will notice that, “Oh my gosh, the music can be beautiful, like… incredible”. And this music, maybe you have heard it before, maybe not. Maybe your brain is generating it on the fly. But it has a quality to it that is extraordinarily hedonic and pleasant. And I remember studying this on myself over many lucid dreaming experiences. At first, I thought, “Oh my gosh, my brain is just unlocking this ability to create awesome harmonies and melodies”. But then I ended up realizing that even if I just make a kind of an “om”, this meditation sound, even though that sound is extremely simple, the quality of the sound in the lucid dream is profound. I mean, it’s almost kind of a surround sound, like 360 surround sound, and stereoscopic and full of reverb and richness. 

I would claim that it’s actually because, during a dream state, your brain is more resonant. You can kind of enter into these very, very resonant attractors, and it’s that quality that makes the music so compelling, not the melody. If you transcribe the melody, the melody may not be very significant. It was how it sounded that was so profound in the music in the dream.

Then you have meditation. Even these images, maybe, I don’t know if this is cheating, but representations of meditation, like high attainments, and so on, they usually come with these beautiful symmetries and whatnot. If you examine the phenomenology of jhanas, how they’re described, there seems to be kind of this projection of less and less information content in your experience. Going from having all of your attention concentrated in one point to then the experience of completely perfectly smooth, boundless space to then just pure consciousness, and then the experience of neither nothing nor something. In a sense, that’s kind of approaching the limit of zero information. And then people report these jhana experiences, they’re not pleasant in a conventional sense. It’s not like eating ice cream or something like that, but they’re still very, very high valence. They’re blissful, in an exotic way. But, I do want to point out that there’s this fascinating, strange relationship here between low information content and the blissfulness and the healing quality of the state.

And then there is exotic valence from psychedelics. I mean, again, I don’t want you to focus on the intentional content, what was the experience about. What you thought, of course, can influence your valence, but it’s more about the phenomenal character. There’s this phenomena of tracers, you move your hand around, and you see copies laying around, and in a sense, it’s giving a temporal depth to your experience. It’s almost kind of adding a new dimension of time, where qualia can pile up. And usually, if the trip is good, you’ll notice that these tracers are in a harmonic relationship with each other. That is kind of the essence of what makes them feel so good.

Likewise, there’s a psychedelic texture repetition. You stare at a piece of grass on LSD, and it starts to symmetrify. And I would totally say this is exotic valence because you ask the person, and they will say “the ground was symmetrifying, and I don’t know why, but it was awesome”. There was something really cool about it, and why would that be? Our interpretation here is that psychedelics are, in a sense, unlocking the valence capacity of your visual cortex. It’s kind of transforming your cortex into a pleasure machine, basically allowing it to exhibit these profound symmetries, and that is what actually is making them feel so compelling. People will struggle to explain “Why were the visuals cool? Why were they interesting?”. When it comes down to it, I think it is the symmetry.

Interestingly, these are called the wallpaper symmetry groups. There’s 17 possible ways of tessellating a two dimensional space. From subjective reports, we know that any of these can be experienced on a psychedelic. The ground, kind of chaotically, will arrive at one attractor of symmetry. It could be any of these 17, and they all feel great. They’re all extremely aesthetic and beautiful and blissful in one way or another. But it’s kind of a testament to just how general this effect is.

I would make the claim, and this is obviously a strong claim, but it matters for something like therapy, psychedelic therapy. We recently saw this fascinating research on psilocybin for major depression, and that a lot of these effects are mediated by whether you had a mystical experience or not. I would say that if you did have a mystical experience, and it was healing, I would bet that while you were having that experience, the sense of space and time was basically extremely, extremely symmetrical. And here is kind of why it’s so confusing. Because you come back and you say, “Well, I saw Jesus”, and you think that you got healed because of Jesus. I don’t want to dissuade you from that view, but I would basically ask you “Okay, but when you experienced Jesus, what was the feeling of space and time?”. They might say something like, “Oh, it had a beautiful light. It had this beautiful harmony and rainbows”. And I’ll claim that if you introspect on them then that it’s actually the quality of phenomenal space and time that is healing and blissful. The meaning, the religious meaning, is something that is helping your mind basically concentrate on that space, and take it seriously as a way of propagating this negentropy in your nervous system.

Now, another place where this shows up super, super clearly, phenomenologically, is on DMT. I definitely recommend this article we wrote that basically charts the DMT space. You can know a lot about where you are in the DMT space by describing what is your energy level on the one hand, and then what is the information content on the other. I would say DMT states that have close to zero information content would be kind of these geometric, perfectly repeating, symmetry groups, either 2D or 3D. Whereas, more chaotic states would be kind of in the middle. The energy level would be a matter of dose. The “height” you reach is very, very dose-dependent. But then the valence, I think it’s very, very dependent on actually where in the axis of information content you find yourself in.

Here again, there’s this diagram that the most blissful experiences you may have on DMT are going to be on these kinds of honeycombs and perfectly symmetrical patterns. The most unpleasant experiences are going to be just right next to those, they are going to be kind of dissonant honeycombs. Whereas you know, when you get to complex narratives, like machine elves and alien realms and all of that stuff, those experiences would be very mixed in their valence. There’s both dissonance, consonance, symmetry, anti-symmetry; those are very complex experiences.

Now, the information content, we think of them as basically attractors in feedback systems. You may end up in a chaotic attractor, you may end up in a limit cycle or a fixed point. And that will determine how much information content the state has. 

Interestingly, this also can be used to describe the difference between DMT and 5-MeO-DMT. We think DMT tends to have a lot more information content. 

So you have these very rich patterns, and I would say competing synchronies. On DMT, there’s all of these slightly different frequencies that are competing for your attention and creating a narrative out of that. That is like a very mixed experience; it is both blissful and distressing at the same time.

Whereas 5-MeO-DMT, which is described as far more powerful emotionally, tends to give you this sense of pure space, like the feeling of the insight into emptiness, the feeling of infinite boundless consciousness, very little information content. Yet, it’s so emotionally impactful to such an extreme extent.

Interestingly, I would say, the reports do come out that on 5-MeO-DMT, you may have the best experience of your time, or you may have the worst experience of your life. It’s kind of bimodal. It’s either amazing or it’s extremely bad. Often, it starts out really bad and then it gets amazing. I would describe that in terms of kind of this annealing process where it basically starts with dissonance, and, over time, things synchronize, and you do end up where all of your nervous system is entrained to the same frequency, and that feels very, very blissful. Whereas DMT is always kind of in this mixed state. It is very difficult for DMT to be pure negative or pure positive. It’s always this mixed state. So I would say, yeah, this is kind of the phenomenological case for the Symmetry Theory of Valence.

I’m two thirds of the way through the presentation. I’m just gonna walk you through the empirical evidence. So we were talking about phenomenology; that’s one of the projections of this formalism and its symmetry. There’s symmetry in the formalism. It’s gonna manifest in some forms of phenomenological symmetry. Likewise, you know, if you use external stimuli in order to generate a state, like, let’s say, watching a movie, playing music, playing stroboscopic stimulation, there’s a lot of evidence that indicates that the symmetry of the stimuli is the leading factor for how pleasant or unpleasant the resulting state is. We have all of this research in vision.

These are just some examples. It’s so stunning, right? Even if you know the effect, you still get the valence response. You go to a cathedral and think “Okay, I’m not gonna get high valence, I’m not going to get high valence”. You still get the response. It’s pretty automatic. As long as it has this rich, deep symmetry, oftentimes, it’s going to be very beautiful. There’s something very compelling about this.

Just some random pictures to give you a sense of this.

Why does this feel good? It really has very little to do with our ancestral environment.

Anyway, this is such a robust effect that, with the symmetry of faces, for example, even face paint can be used to modify the valence. So, if you don’t have a perfectly symmetrical face, but you add symmetrical face paint with beautiful patterns, you’re going to be judged as more beautiful. It’s just such a strong effect, that it can actually modify your perception of how beautiful somebody is. Likewise, if you add asymmetrical patterns, you look less beautiful. Now, this, I wouldn’t say this is that strong of evidence because this actually does have an evolutionary reason. Symmetry in faces is a marker of mutational load. So I don’t put that much stock in, symmetry of faces being that relevant. But symmetry in other forms is where I think it’s so stunning. 

You also see this in symmetry in audio, basically, regular rhythms. Harmony is the leading predictor for whether a sound is going to be pleasant or unpleasant.

You know, this is Helmholtz’s big idea. He was the first one to figure out why playing two notes in a piano that are one semitone apart feels unpleasant. It’s because the harmonics are basically within what’s called the critical window. They generate beat patterns and the beat patterns can be described as basically symmetry breaking operations in the waveform. Those symmetry breaking operations, in essence, cause irritation. So basically, the more beating there is in sound, and the more beating across the spectrum, the more irritating and distracting and rough the sound is going to sound like. Whereas, when you have these harmonic relationships, you play one note, one piano note, and another at an octave of difference, the harmonics line up perfectly. Actually, the sound is very compressible because you don’t have this extra information of where all the other harmonics lie. They’re just the harmonic sequence. And that is universally described as a more pleasant sound.

When you add up all the harmonics, you get these interesting curves. The height here is the amount of dissonance. When you have a relationship of one to two, basically an octave, you have zero dissonance, and that feels really good. Now, music is very complicated. We have to factor in the boredom mechanism. If you just play the same octave over and over, you get bored, and there’s an inner sense of restlessness and dissonance. But if you just hear it for the first time, then there’s a super, super strong relationship between symmetry and valence.

These are just examples of a piano chord.

Dissonant sounds. I can send you a link to all of these sounds after the presentation*, but I have some links for a SoundCloud account where you can kind of get convinced that “Oh gosh, these are actually really bad sounds”. It’s not that I’m saying they’re bad. If you ask 100 people, like 99% of people will say they’re awful. 

Likewise, reverb basically symmetrifies any waveform. Reverb is almost kind of this hack that you take almost any dissonant sound and you add reverb to it and is going to sound a lot less bad, a lot less distracting, irritating, and so on. So this is comparing the sound of a baby crying, which by the way, like in our analysis, it shows that babies crying, it’s almost like their sound is optimized for dissonance. It’s almost kind of as dissonant as it gets for a sound made by a human. For good evolutionary reasons, it has to be distracting, and catch your attention, bring the desire to stop it. But you add reverb and to give you a sense, that’s like if the baby was in a huge cave, you get all these echoes averaging out the beat patterns. It sounds way better, way less distracting, probably not good from an evolutionary standpoint. But, it’s just a fascinating kind of transformation you can apply to any waveform.

And here, I just want to illustrate that valence can happen across the spectrum. So I also have this file**, and you’re welcome to listen to it after the presentation where you can have consonance anywhere in the spectrum, mixed in with dissonance anywhere in the spectrum, mixed in with noise anywhere in the spectrum. That ends up basically creating these very mixed states. 

So basically, when I say “Oh, I had a mixed experience, a mixed valence experience” that underdetermines what I experienced because we don’t know if the positive part was in the high frequencies or in the low frequencies. We don’t know that. That’s why the full picture of valence would also include the spectrum for positive, negative, and neutral valence. You can have high frequency pleasure, you can have low frequency pleasure, etc. So that kind of explains why there’s a tremendous diversity of possible mixed experiences even though ultimately they’d still come down to symmetry. Deep down, they can all still be explained with symmetry.

Now, endogenously generated symmetry, this is fascinating research. That when you have this “biorhythm coherence” you feel happier. And the way of computing biorhythm coherence is very related to musical consonance. Breathing entrained with heart rate variability is reported as giving rise to a just much, much better positive mood, and is one of the things that long-term meditation achieves. Meditation entrains these biorhythms and basically makes them interlock with one another. That is reported as giving rise to positive mood which is an interesting finding and very consistent with STV.

Here are just some quotes. Cool.

And you know, the heart palpitations. I mean, it’s similar to anxiety in that if you have like this usually regular metronome, and it’s failing, is generating these imperfections, that gives rise to unpleasant states of mind. I’m sure heart disease is terrible for your valence. Likewise, meditation is a wonderful tool for heart disease because it allows you to overcome those imperfections and still feel good despite the problem.

In terms of other endogenously generated symmetry, I will mention orgasm and flow. Orgasm is a powerful generator of endogenous resonance. It’s the entrainment of motor systems to near hallucinations, to synchronizing feedback processes across multiple functional networks. With an orgasm, there’s a deep, deep level of synchrony and symmetry across the nervous system. I highly recommend introspecting on this (not to get into your sex life or anything, though). I mean, it’s something you can actually pay attention to, and it becomes very obvious once you notice it. 

Likewise with flow, there’s this evidence that symmetry is deeply related to flow. Two physiological metrics for measuring flow are cortical muscular coherence and a degree of coupling between neural EEG waves and EMG oscillations of muscle activity. So, there’s also these interlocking patterns, lower information content, more symmetry. Yeah, it’s a strong predictor of flow. So like, hey, go figure flow is also symmetrical.

Okay, let’s get into the symmetry in the brain. So this is kind of the other projection you could take of the latent state. If you look at the central nervous system of high valence states, how does the valence show up? And, you know, meditation, like all over the place, basically pretty much any kind of meditation, if done for a long enough time, leads to some kind of EEG coherence. Whether it’s gamma coherence, delta coherence, or alpha coherence, depends on which kind of meditation you do. But they all generate some form of coherence, and coherence in EEG is intimately related with symmetry. I mean, basically, two signals are coherent when they’re both reflections of a shared signal through a reverb pattern, meaning that they’re encoding the same information just through a different filter, which is, again, deeply, deeply connected to symmetry. 

Here’s a fascinating study from 2019 that I recommend reading which to me was really stunning. It was stunning in just how clear the connection with the Symmetry Theory of Valence was. The study is about the EEG recordings of the first and second jhanas and the interesting patterns that emerged in them. One of them is this seizure-like activity. Now, seizure-like activity is three to five hertz, and it doesn’t have harmonic structure. I mean most seizures don’t have their harmonics together with them. But the type of seizure-like activity you see on jhanas does have harmonic structure. And the picture here is basically the Fourier transform of the independent components of the EEG recordings. You can see there’s a very clean 5.6 hertz signal, together with its harmonic of 11.23 hertz. This is kind of stunning. Why would this happen? And jhanas feel really blissful. Without the Symmetry Theory of Valence, this is just super surprising and strange. With the Symmetry Theory of Valence it’s like, “Oh, yeah, you’re, feeling a really great symmetrical attractor of your brain and sustaining it”. So that’s going to feel good. 

Even you know, ketamine showing high levels of a gamma coherence.

For 5-MeO-DMT, the only dataset I’m aware of, of EEG and 5-MeO-DMT, shows coherence across the spectrum, not only gamma coherence, but also beta coherence, and especially delta coherence. Again, why on earth? The Symmetry Theory of Valence would explain this. It would say, “Yes, this is expected”. Other theories might struggle a bit. Now, I’ve got to say that just because you have high coherence doesn’t mean it’s going to be high valence. We expect also very negative valence could also be high coherence. Except that when you have total coherence, then we expect that to be always positive valence. Again, it’s going to have that relationship because you could still have a high average coherence, but have half of your channels coherent in a certain frequency and half of the other channels coherent in a slightly different frequency. That might actually maximize dissonance. So just average coherence is not enough. You also need to tell whether it’s in harmonic structure or not.

Pleasure in the brain seems to be kind of this distributed effect that also from our point of view would mean it’s actually a whole brain phenomena. 

This is about what I was mentioning about the pleasure centers from our point of view. I mean, there’s this research of if you tried to synchronize clocks, and you tried to synchronize neurons, and you put them in a geometric grid. If it’s large enough, you’re not going to usually get full scale synchrony. You might have emergent patches of synchrony or traveling waves of synchrony. But if you also add these random connections across the network and reduce the synaptic path length, then you can unlock the ability for the entire network to enter synchrony. So we think of the pleasure centers as kind of these bridges that are, in a sense, lowering the average synaptic path length across your brain, and therefore enabling similar synchrony across the brain. And that’s the reason why we think the pleasure centers generally feel good when you activate them. 

Okay, getting to the end of the presentation. So I’ll just talk about a few near “enemies”. I put “enemies” in quotes, because we actually admire these people. They’re part of our research lineages. I think they’re a very, very key component of any good theory of consciousness. But I think when it comes to valence itself, there’s some explanations in the space that are really close to the Symmetry Theory of Valence, but they’re not exactly what we’re getting at. So there’s this whole account of computational efficiency. The brain likes computational efficiency, but in a sense, you still have to explain why the brain likes computational efficiency- what does this liking manifest as? We use this argument of “passing the bucket” which ideally your theory of valence should avoid. The theory should explain what valence itself is, not only when it gets triggered. These theories of computational efficiency, energy efficiency, we would claim, they’re telling you under what conditions positive valence gets triggered, but they don’t tell you what positive valence itself is. And that’s what the Symmetry Theory of Valence is getting at. 

So yeah, these are some of the issues with those, at least as complete theories.

Finally, okay, counter examples. There’s this whole theory I recommend reading called Neural Annealing (by Mike Johnson). But even very neutral energy that neither has harmony or dissonance, can still give rise to very positive feelings because it can give rise to this annealing process. And that’s actually what we believe is going on with psychedelics. Psychedelics gives you what Mike would call semantically neutral energy. And that gives rise to basically this entropic disintegration, a term from Robin Carhart-Harris and the entropic brain hypotheses, which then gives rise to kind of this search, or self-reorganisation that basically will settle on these basins of symmetry. And it’s those that feel good, not the energy that feels good. It is the end result, the attractor that it takes you to.

And this explains, I think, why even somebody can like hot sauce. Hot sauce is kind of this unpleasant stimuli, but it can lead to euphoria. It can lead to this heightened state of energy. If you introspect on the euphoria of hot sauce, it’s not the unpleasant pain in the mouth, it’s that it raises all of your energy, your entire amount of the intensity of your consciousness. You can then notice these resonant waves, and it is those resonant waves that feel good, not the hot sauce itself. So there’s this kind of a step that basically separates one from the other.

I’ll just very quickly, briefly describe one way we’re trying to test the Symmetry Theory of Valence. It is not the only way to test it. I would even argue that, you know, the argument that I here presented is itself a potentially strong argument. But ideally, you know, we generate novel predictions. And this is one of them, which is that we basically expect that the very positive states of consciousness will have a harmonic relationship, basically a consonant relationship between the brain harmonics. Yeah, using the work of Selen Atasoy.

This algorithm of quantifying the amount of consonance in brain harmonics, which is something we were working with, and hopefully will get resolved soon.

We anticipate that, again, if this is true, the Symmetry Theory of Valence would be validated. If it’s not, it doesn’t invalidate it, because there’s many ways in which it can manifest. But when you have harmonics that are in a consonant relationship with each other, and those are the main drivers of your experience, we expect that to be pleasant.

That is, euphoric.

Whereas, when you have harmonics that are dissonant with each other, they generate these intense beating patterns. So we expect that to be described as unpleasant. Again, we don’t know, but we want to check if this is true. 

Just a couple testable predictions based on this, which is that we expect psychedelics to enhance the range of valence. Basically, psychedelics enhance energy across the board. Just all of the harmonics have more energy. We expect that some of those combinations will be just very consonant and reported to be very pleasant, some of those will be very dissonant, reported to be unpleasant. Then SSRIs, there’s a lot of research on SSRIs and their blunting effects. They cut the extremes of valence. So, we expect when it comes to harmonics that the SSRIs will be more noisy, less consonant, less dissonant. MDMA, we expect it to be a stable attractor of a few resonant modes that are very consonant with each other. Stimulants would be kind of high frequency consonance. Opiates would be low frequency consonance. Again, this idea that you can be in a good state leaves underdetermined whether there are symmetries in the high frequencies or the low frequencies, and this would disentangle these types of mixed experiences.

These are the last two or three slides which is kind of a case study which is SSRI’s. Roughly speaking, we interpret them as being noise inducers which is why things like orgasm on SSRIs are less intense. Crying is hard. I mean, crying itself is a kind of a dissonant and sometimes consonant, kind of resonant state. On SSRIs you feel kind of spaced out and music enjoyment goes down. So yeah, the way we think of SSRIs is that they’re almost kind of like listening to a white noise machine along your life, so it’s gonna cut off the extremes. It’s gonna blunt both very positive and very negative valence, and it’s gonna just kind of center you in neutral valence.

Whereas psychedelics, they basically kind of purify and intensify your harmonics. And in that sense, you get to have more pleasant and more unpleasant states and both extremes.

Just to remind you: introspect. I compel you, next time you’re on a psychedelic having a mystical experience, introspect on the quality of space and time. I suggest that you will probably be experiencing these kinds of beautiful ripples that are in a harmonic relationship to each other. Please email me if this is true or not true. But that’s the experience so far. And that’s the reason why this can feel so amazing. 

The future of mental health, ideally, would be that we can identify, “what are the sources of dissonance in your nervous system?” and then find the shortest path to the smallest change possible that will give rise to sustainable consonance in your nervous system. Whether this is going to be with meditation, a psychedelic session, or yoga, or biofeedback will be person-specific. There’s probably a shortest path from a highly dissonant dysfunctional state to a sustainable consonant state for each person.

And with that I just want to say thank you to other people in the team of QRI. And thank you, Robin, Shamil, and all of you guys for attending this presentation. And to the Centre for Psychedelic Research for hosting this presentation.

Thank you so much.

Modeling Psychedelic Tracers with QRI’s Psychophysics Toolkit: The Tracer Replication Tool

Try it yourself!

By Andrés Gómez Emilsson (see special thanks)


We developed a new method for replicating psychedelic tracer effects in detail: the Tracer Replication Tool. This tool gives us a window into how the time-like texture of experience determines the state of consciousness we find ourselves in, which clarifies what makes both meditating and taking psychedelics such powerful state-switching activities. We discuss how the technique of using the tracer tool may find useful applications, such as allowing us to describe exotic “ineffable” experiences in clear language, standardize a scale of intensity of psychedelic drug effects (a.k.a. a “High-O-Meter”), help us quantify the synergy between different drugs, and test theories for what makes an experience feel good or bad such as the Symmetry Theory of Valence. The pilot data collected with this tool so far is suggestive of the following patterns: (1) THC and HPPD result in a smooth and faint trail effect. (2) The characteristic frequencies of the strobe and replay effects for 2C-B are slower than those of either DMT or 5-MeO-DMT. And, (3) whereas DMT comes with a strong color pulsing effect leading to very colorful visuals, 5-MeO-DMT gives rise to monochromatic tracer effects. We conclude by discussing the implications of these patterns in light of an analysis of experience that allows for a varying time-like texture. We hope to inspire the scientific community and curious psychonauts to use this tool to help us uncover more patterns.


Rhythmic activity in the brain is a staple of neuroscience. It shows up in spiking neurons, synchronous oscillations at the level of networks, global patterns of resonance and coherence in EEG recordings, and in many other places. The book Rhythms of the Brain by György Buzsáki is a systematic review of what was known about these rhythms back in 2006.[1] One of the things György talks about in this book is how a lot of neuroscience techniques focused on finding the neural correlates of perception tend to consider the variable activation of neurons from one trial to the next as noise. In experiments that look into how neurons respond to a specific stimulus, datasets are constructed that track the neuronal activity that stays the same across trials. That which changes is discarded as noise, and György argues that such “noise” is really where the information about the internal rhythms is to be found.[2] We concur with the assessment that understanding these native rhythms is key for making sense of how the brain works. Perhaps one of the most exciting developments in this space is the method of Connectome-Specific Harmonic Wave analysis (Atasoy et al., 2016). This way of analyzing fMRI data describes a “brain state” as, at least partly, consisting of a weighted sum of its resonant modes. This paradigm has been used with success for comparing brain states across widely different categories of experience: LSD, ketamine, and anesthesia, among others (Luppi et al., 2020).

These are exciting times for exploring the native rhythms of nervous systems in neuroscience. But what about their subjective quality? One would hope that we could connect a formal third-person view of these rhythms with their experiential component. Alas, at this point in time the behavioral and physiological component of brain rhythms is far better understood than the way in which they cash out in subjective qualities.

Could there be a way to make these rhythms easily visible to ourselves as scientists? One interesting lens through which to see psychedelics is in terms of the way they excite specific rhythm-generating networks. This lens would present psychedelic states as giving you a sense of what it feels like to have many of these rhythms simultaneously activated, thus having access to a wider repertoire of brain states (Atasoy et al., 2017).

But you don’t need psychedelics to realize there’s something fishy about the solidity of our perception. Intuitively, one may get the impression that normal everyday states of consciousness do not show the signatures of being the result of ensembles of rhythmic activity. That said, some would affirm that paying attention to the artifacts of our perception may in fact be a window into these rhythms. For example, Lehar’s Harmonic Resonance Theory of the gestalt properties of perception (Lehar, 1999) attempts to explain the characteristics of well known visual illusions (such as the Kanizsa triangle) with principles derived from the superposition of rhythmic activity.

Kanizsa Triangles

Paying close attention to the act of observing an object over time has led some researchers to play with the idea that our experience of the world is best understood as music (Lloyd, 2013), for our feeling of a solid surrounding results from the interplay between finely coordinated sensations and acts of interpretation. Indeed, the fluidity of sensory impressions betrays our common-sense notion that we experience a solid and stable world. It often takes a perturbation out of our normal everyday state of consciousness to notice this. As an example here, we can point out that insight meditation practices peer into the illusion of solidity and continuity of our experience, whereas concentration meditation enhances these illusions (Ingram, 2018).

Arguably, like a fish who cannot notice water until it’s taken out of it, the stitching process by which our brain constructs reality is usually hidden from view. To be taken out of the water in this context would be to be in a state that allows you to notice the seams of one’s experience. To the extent that this normal stitching process breaks down in exotic states of consciousness, they are clearly useful for research in this domain. Thus we argue that the artifacts of perception in alien states of consciousness are not noise; they provide hints for how normal experience is constructed. In particular, we posit that “psychedelic tracers” (i.e. the cluster of persisting visual phenomena caused by hallucinogens) may be a window into how rhythmic feedback dynamics are used to control the content of our experience. For this reason, we have been interested in turning what until now has been qualitative descriptions and informal approximations of this phenomenon into concrete quantitative replications.

In what follows we will showcase the value of a psychophysics toolkit we developed at the Qualia Research Institute called the Tracer Replication Tool for modeling psychedelic tracer phenomenology. Although we will focus on psychedelic experiences, this tool can have a much broader set of applications. For example, we show how the tool can be used to visualize and quantify the severity of HPPD, which currently has a very qualitative, and imprecise at best, diagnostic criteria. Likewise, the tool has the potential to bring together the complex clinical presentation of visual disturbances such as palinopsia, photopsia, oscillopsia, visual snow, and other conditions, into a coherent framework. Perhaps, speculatively, the connection between all these visual disturbances is to be found in the dysregulation of the rhythms of the visual control systems, which is what the tracer tool sets out to quantify.

The only attempt of arriving at quantitative replications of psychedelic tracers in the scientific literature we are aware of is by (Dubois & VanRullen, 2011). They used multiple-exposure stroboscopic photography in order to depict video scenes. They then asked many people who have had LSD experiences to identify the strobe frequency that best approximated their tracers (which on average was in the 15-20 Hz range).

As we will see, our model for psychedelic tracers is more detailed: it has multiple persistence of vision effects that combine together into a complex tracer. For this reason, the kind of tracers used in Dubois & VanRullen turn out to be a special case of our tool, which we call the strobe effect:

LSD users perceive a series of discrete positive afterimages in the wake of moving objects, a percept that has been likened to a multiple-exposure stroboscopic photograph, somewhat akin to Etienne-Jules Marey’s chronophotographs [5] from 1880, or to more recent digital art produced in a few clicks (Figure 1).

By using a wider set of effects, the Tracer Replication Tool might give us hints about how psychedelics disrupt native rhythms given how they affect the processing of perceptual information at a granular level.

Before we provide the full set of tracer effects along with their associated vocabulary, let us jump into the preliminary psychedelic replications we have obtained thanks to this tool.

Psychedelic Replications

Over the years since I’ve run the Qualia Computing blog, I’ve received many messages from people who, for lack of a better term, we could call rational psychonauts. This should not be too surprising, with pieces like “How to Secretly Communicate with People on LSD” and “5-MeO-DMT vs. N,N-DMT: The 9 Lenses”, the site has become a bit of a Schelling point for people who like to blend computational reasoning and the study of exotic states of consciousness. These rational psychonauts are people who not only are well acquainted with exotic states of consciousness, but also like to use a scientific and rational lens to make sense of such states. In particular, people in this cluster often ask me to send them experiments to try out next time they take a psychedelic substance. I certainly never encourage them to take drugs, but under the assumption they will do so anyway, I sometimes send them tasks to do. Thus, once we had a prototype for the tracer tool, I already had a set of more than willing anonymous pilot participants. I sent them the link to the tool along with some brief instructions. Namely:

Look at the ball for a few minutes in state X (where X can be any substance, meditation, etc.). Then as soon as you come down, try to fiddle with the parameters on the left until the simulated tracer looks as close as possible to how you experienced it in the state. When you are ready, simply click “submit parameters” and add info about what the state you were in was at the time. In the case of HPPD, just try your best to replicate the tracer (I know it gets confusing when we talk about the tracers of the simulated tracers, but try to ignore those and just replicate the tracer of the original input).

Without further ado, here are the resulting replications I received:


Mild HPPD (participant said it was strongest on color red)


12.5mg edible, 60 minutes post-ingestion
15mg edible, 90 minutes post-ingestion


20mg orally ingested
12mg “gummed”

Notice how although the replication of the higher dosage is more mild in a way, they both share the presence of a strobe effect at roughly 5.5 Hz!


5mg vaped
10mg vaped
20mg vaped

The higher dose has a complex mixture of effects, including 40 Hz color pulsing (positive and negative afterimages mixed together), 22 Hz replay, and 27 Hz strobe. I’ll note that the participant included the following comment: “Aside from extremely fast tracers, the white space consisted of pixelated fractals. Color was abundant.”


5mg vaped
10mg vaped

As we will discuss further below, it is worth noting that at least in this sample, there are no color pulsing effects present (which is unlike “regular” DMT).

Drug Combination: Mescaline + ETH-LAD

125μg ETH-LAD + 2 teaspoons of San Pedro powder

The above is the only datapoint we have so far from the combination of psychoactive substances. The participant took 125μg of ETH-LAD, and then two and a half hours later 2 teaspoons of San Pedro powder. The replication is of the way the ball looked like 5 hours after taking the first drug.


Let us now look into the specifics of the tracer tool:

Core Effects

Core effects are pillars of the tracer tool where a particular feedback dynamic is used. The core effects include trails, strobe, and replay.


A modifier effect is one that plays with a core effect and alters it in some way. We will talk along the way about the modifying effects of persistence, intensity, and frequency, and then have a separate section to talk in more detail about the modifier effects of envelope (ADSR), pulse, and color pulse.

Trails (Core Effect)

This is perhaps the most basic effect. Making an analogy with sound, trails are akin to a soft reverb with no delay:

The three settings for trails are: persistence, intensity, and exponential decay (which is binary in the current implementation and otherwise takes on the value of linear decay). Persistence determines how quickly the tracer vanishes, whereas intensity is a constant multiplier for the entire trail. Thus, by changing those parameters you can choose between e.g. a long but dim trail or a short but bright trail.

High persistence / low intensity

Low persistence / high intensity

The exponential decay parameter slightly changes how quickly the brightness goes down; when it’s on, the trails go down more smoothly (cf. gamma correction).

Without exponential decay

With exponential decay

Strobe (Core Effect)

The strobe effect takes snapshots of the input at regular intervals. It works like chronophotography, and it is perhaps what most people think about when you first talk about visual tracers. It is the effect that Dubois & VanRullen used to find that LSD produces visual tracers at ~15-20 Hz.

Strobe effect at 16.4 Hz

The strobe effect, just as the trail effect, also has intensity, persistence, and exponential decay modifiers. In addition, it also has frequency, which encodes how many snapshots per second are being taken.

5 Hz Strobe

10 Hz Strobe

20 Hz Strobe

Note: The current implementation of the trails feature is done with a very fast strobe. In this way, when you set the strobe frequency to the maximum you get something that starts to look a little like the trails effect.

Replay (Core Effect)

With an analogy to sound, replay would be akin to adding an echo or delay to a signal. Replay adds to the raw signal a copy of the output from a fraction of a second into the past. The result is a current output that contains a sequence of increasingly dimmer video replays of itself at regular time intervals into the past.

6 Hz Replay

As with strobe, replay has intensity, persistence, exponential decay, and frequency as its modifying effects.

3 Hz Replay

12 Hz Replay

Note: the replay effect is difficult to distinguish from the strobe effect with only still images

Pulse (Modifier)

This is a modifier effect that can apply to trails, strobes, and replays (right now the implementation only applies to strobe, but we may change that in the future). It takes a fraction of the input and modulates it with a sine wave at a given frequency. This way the trails, strobes, and replays can come and go (either in part or in full) at a given frequency. This adds sparkle to the experience, and it can plausibly help create a sense of reality or object-permanence for the hallucinations as they “vibrate at their own frequency”.

Compare the difference between a strobe at 4 Hz vs. a strobe at 4 Hz with a pulse at 2 Hz:

4 Hz Strobe
4 Hz Strobe + 2 Hz Pulse at 50% amplitude

As you can see, the pulsing effect makes the strobes look like they have a sort of life of their own.

ADSR (Modifier)

This modifier effect was something we decided to add because James Kent of Psychedelic Information Theory (Kent, 2010) talks about ADSR envelopes for tracers in the section titled “Control Interruption Model of Psychedelic Action”:

Using control interrupts as the source of hallucinogenesis, we can model hallucinogenic frame distortion of multisensory perception the same way we model sound waves produced by synthesizers; by plotting the attack, decay, sustain, and release (ADSR envelope) of the hallucinogenic interrupt as it effects consciousness. (Fig. 2)3,4 For example, nitrous oxide (N20) inhalation alters consciousness in such a way that all perceptual frames arise and fall with a predictable “wah-wah-wah” time signature. The throbbing “wah-wha-wah” of the N20 experience is a stable standing wave formation that begins when the molecule hits the neural network and ends when it is metabolized, but for the duration of N20 action the “wah-wah-wah” completely penetrates all modes of sensory awareness with a strobe-like intensity. The periodic interrupt of N20 can be modeled as a perceptual wave ambiguity that toggles back and forth between consciousness and unconsciousness at roughly 8 to 11 frames-per-second, or @8-11hz.5 Consciousness rises at the peak of each “wah” and diminishes in the valleys in between. On sub-anesthetic doses, N20 creates a looping effect where frame content overlaps into the following frame, causing a perceptual cascade similar to fractal regression. We can thus model the interrupt envelope of N20 as having a rounded attack, fast decay, low sustain, medium release, with an interrupt frequency of @8-11hz. Any psychoactive substance with a similar interrupt envelope will produce results that feel similar to the N20 experience. (Fig. 3) For instance, Smoked Salvia divinorum (vaporized Salvinorin A&B, or Salvia) has an interrupt envelope similar to N20, except Salvia has a harder attack, a slightly longer decay, a more intense sustain, a slightly longer release, and a slightly faster interrupt frequency (@12-15hz).6 These slight changes in the frequency and shape of interrupt envelope cause Salvia to feel more physically intense, more hallucinatory, and more disorienting than N20, even though they share a similar throbbing or tingling sensation along the same frequency range.

The chapter about the Control Interrupt Model of Psychedelic Action in Psychedelic Information Theory by James L. Kent

“Figure 2.” (source)

This actually seems to be important for showcasing what makes drugs with similar characteristic frequencies capable of feeling so different.

2 Hz Strobe
2 Hz Strobe + soft ADSR pattern

A really interesting research lead that is connected to the ADSR envelope of psychedelic tracers can be found in The Grand Illusion (Lehar, 2010), where cognitive scientist Steven Lehar narrates some of his experiences with LSD vs. LSD + MDMA. One of the things he discusses is the way that MDMA makes the experience jitter in a pleasant way that results in the LSD visuals becoming smoother (emphasis mine):

Under LSD and ecstasy I could see the flickering blur of visual generation most clearly. And I saw peculiar ornamental artifacts on all perceived objects, like a Fourier representation with the higher harmonics chopped off. LSD by itself creates sharply detailed ornamental artifacts, like a transparent overlay of an ornamental lattice or filigree pattern superimposed on the visual scene, especially in darkness. Ecstasy smooths out those sharp edges and blurs them into a creamy smooth rolling experience.

The Grand Illusion (pg. 62) by Steven Lehar

I would suspect that this distinction will become legible with the judicious use of ADSR envelopes. Below you will find a possible rendition of this effect:

10.3 Hz Strobe (maybe LSD)
10.3 Hz Strobe + soft ADSR pattern (maybe LSD + MDMA)

As we will discuss further below, a more creamy ADSR envelope may cash out in a more pleasant experience, whereas a sharper or spikier envelope may in turn create more harsh experiences.

Color Pulse/Negative After Images (Modifier)

The color pulse effect transforms the image’s color towards its opposite in the CIELAB color space with a given frequency. It modifies strobe, replay, and trails (in principle, there can be a different color pulse for each effect, but for now it modifies all three simultaneously).

23.6 Hz Strobe
23.6 Hz Strobe + 2 Hz Color Pulse

Unlike pulse, color pulse modulates the color rather than the brightness of the input. The way we determine what color to transform into is by going to the opposite side of the CIELAB color space. This accurately approximates the negative afterimage of any phenomenal color (such as yellow being the negative afterimage of blue, and green being the negative afterimage of red). In our current implementation, color pulsing affects strobe and replay quite differently. For replay, the effect is one where there are now versions of the ball (or image, more generally) that have the opposite color that are chasing the original ball, whereas for strobe the effect is that of giving a seizure to each of the recent snapshots of experience! See for yourself:

26 Hz Replay + 13 Hz Color Pulse
26 Hz Strobe + 13 Hz Color Pulse

In a future version of the tracer tool, color pulse may become a sub-property of each main tracer layer in the same way ADSR is a sub-property of the strobe and replay layers.

Color pulsing may be an important piece of the puzzle for understanding how otherwise similar drugs can have such dramatically different effects. Tentatively, color pulsing showed up as a distinction between DMT and 5-MeO-DMT according to one of the persons who submitted parameters (as you can see above in the replication section). For that person, DMT produced color pulses while 5-MeO-DMT did not. Of course this is just a sample size of N=1. But it seems like an important research lead if true! After all, DMT trip reports do talk of highly colorful hallucinations that typically involve the combination of colors and their opposites (e.g. “The wall looked like a Persian carpet with an alternating checkerboard pattern design of neon green and magenta light” – anonymous 10mg DMT), whereas most 5-MeO-DMT trip reports don’t feature color very much. In fact, 5-MeO-DMT trips are often in black and white, pure white, pure black, or “nothingness color”. We discuss the implications of this in more detail in the last section of this piece (Getting Realms from Time-Like Textures).

Face Value vs. Dynamic Feedback Model

It is important to point out that the tracer tool works under the assumption of linearity between the effects it models. In other words, each effect modifies the input in its own way, and the corresponding modifications are added linearly at the end. This does not need to be the case. And in fact, we must expect the brain to have a lot of complex non-linearities where e.g. the pulsing effect is then used in a replay loop which entrains a strobing pattern which focuses your attention and so on. This complication aside, there is a lot of value in postulating the simple model first, and then adjusting accordingly when it fails to model the more complex phenomena. When we get there, once we have identified particular drugs, doses, and combinations that produce strange nonlinearities, we can then build tracer tools that explore how the parameters of particular dynamic systems can best explain the empirical data. Until then, let us start mapping out the space with this (relatively) simple linear model.

Useful Vocabulary

I would like to highlight the fact that using the tracer tool can be very educational. Familiarizing yourself with the effects and their modifications will allow you to be able to describe in detail psychedelic tracers even without having to use the tool again. For instance, I find myself now able to describe what kind of tracer effect appears on any given replication or trippy video. For example, now that you have read about them, can you tell us what is going on in the following gifs?:


The Explanatory Power of the Time-Like Texture of Experience

Exotic Phenomenal Time

We have previously suggested that tracers in the most general sense (i.e. including tracers for emotions, thoughts, and all sensory modalities in addition to visual experience) are very important for understanding the time distortions one experiences in exotic states of consciousness. The overall idea is that the aspect of our experience that gives rise to the feeling of time passing is the result of implicit causality in the network of local binding connections, which we call the pseudo-time arrow (see a recent presentation about it). Don’t worry about the details, though. All you need to know is that here we model phenomenal time as the direction along which causality flows within one’s experience. And because this is a statistical property of our experience, it turns out that phenomenal time ends up being very malleable; it admits of “exotic phenomenal time” variants:

This framework can articulate what is going on when you experience crazy psychedelic states such as moments of eternity, time branching, time looping, and so on. Now, even these are just some of the possible ways in which the network of local binding connections can give rise to exotic phenomenal time experiences. In reality, because the pseudo-time arrow emerges at a statistical level in the network, one can have all manners of local pseudo-time arrows nested in complex ways, as briefly discussed in the presentation:

 I will end by speculating: I just walked you through seven types of exotic phenomenal time, but if indeed [the experience of time] can be explained in terms of causality in a graph, then there are many other exotic phenomenal times we can construct. This is especially so when we consider the space of possible hybrid phenomenal times. For instance, where in some regions in the network we may find time looping, some other region might be a moment of eternity, and perhaps another region is branching, and you know, if you have a very big experience, there is no reason why you wouldn’t be able to segment different regions of it for different types of phenomenal time. This is not unlike, perhaps, how we think of Feynman diagrams, where this part of it here is moving forwards in time, this part here is doing a loop, this part here is branching… I think a lot of the topologies we see here could be used to represent completely new [hybrid] exotic phenomenal times.

The Pseudo Time Arrow | Andres Gomez Emilsson (2020)

Given the diversity of ways in which phenomenal time can be expressed in an experience, I will start talking about the patterns encoded in the pseudo-time arrow as the time-like texture of experience. This way, rather than assuming that one’s sense of time is globally consistent in a given way (e.g. as in “I am fully inside a time-loop”), we can discuss how various patches and components of one’s experience have this or that time-like texture (e.g. “my visual field was looping, but my proprioception was strobing and my thoughts felt timeless”).


As a generic effect, all psychedelics seem to increase the duration of qualia in one’s experiential field, leading to a buildup of energy. But the precise shape this takes matters a lot, and it is certainly different between drugs. An example pointed above is how LSD and DMT seem to produce strobe and replay patterns of markedly different frequencies. For DMT, the spatial and temporal frequency of the visual hallucinations is usually described as “very high”. Based on the replications thus far, along with personal reports from a musician I trust, DMT’s “characteristic frequency” seems to be in the 25 to 30 Hz range. In contrast, LSD’s frequency is more in the range of 15 to 20 Hz: both Dubois & VanRullen’s LSD tracer study and subjective reports I’ve gathered over the years point to the hallucinations of acid having this rough frequency. Hence, the very building blocks of reality of a high-dose DMT breakthrough experience consist of tiny time-loops and strobe effects interacting with one another, weaving together a hallucinated world with surprising levels of detail and intense freshness of experience (as all the time loops are “young” due to their short duration). Really, when you take a small dose of DMT and you see the walls tessellating into wallpaper groups, notice how each of the tiny “bricks” that make up the tessellation is itself a time loop of sorts! It is not a stretch to describe a DMT experience as a kind of complex Darwinian ecosystem of tiny coalition-based time loop clusters bidding for your attention (cf. Hyperbolic Geometry of DMT Experiences).

Taking this paradigm seriously allows us to interpret psychoactive effects at a high level in novel ways. For example, these are some of the general patterns we have identified so far:

  1. Psychedelics tend to have strong replay and strobe effects
  2. HPPD, cannabis, and dissociatives seem to have a much smoother trail effect
  3. MDMA and 5-MeO-DMT have characteristically creamy ADSR envelope effects

Using the sound metaphor to restate the above, psychedelics introduce beats and recursion, dissociatives introduce reverb, and empathogens/valence drugs may affect the temporal blur of one’s experience. Thus, we arrive at a model of psychoactive substances that makes sense of their effects in the language of signal processing rather than neurotransmitters and functional localization. This sheds a lot of clarity on the mysterious and bizarre state-spaces of consciousness disclosed by psychoactive drugs and paves the way for a principled way of predicting the way drug combinations may give rise to synergistic effects (more on that below). More so, it lends credence to the patternceutical paradigm of drug effects.

Meditation: Insight and Concentration Practices

The pseudo-time arrow paradigm suggests that one of the ways in which meditative practices can switch one’s state of consciousness is by disrupting sober time-like textures and enabling exotic time-like textures not available to the sober mind (see also: The Neuroscience of Meditation: Four Models (Johnson, 2018)). My personal experience with meditative practices is limited, but I’ve had the pleasure of experiencing some strange effects so far. In particular, I would say that concentration practices seem to give rise to experiences with long and stable pseudo-time arrows – a peacefulness in which nothing is happening yet the flow of time is constant and rather uneventful. The phenomenal time of highly focused states of mind may be full of reverb, but I do not think it has crazy time loops. Moments of eternity and timelessness may be present at the limit here (e.g. moments of eternity and Jhanas may be deeply connected), though I will need more personal experience to say this with confidence. 

On the other hand, insight practices such as noting meditation may have more of a replay and strobe effect. In particular, this may happen as a result of three core effects from this kind of meditation: (1) it stops you from dissipating energy across long narratives, (2) it recaptures the energy you were going to use for a longer narrative to feed the noting process instead, and (3) it entrains the rhythm of noting. This in turn (a) energizes a regular constant-frequency pattern (the frequency of noting) and (b) reduces the energy of every other rhythm, which in turn (c) canalizes sensory stimulation energy towards the brain’s noting frequency and all of its harmonics, which eventually leads to a high-frequency energized state of consciousness whose building blocks are tiny time-loops. These can synchronize and create experiences with characteristic time-like textures made up of such tiny energized loops. Hence, noting practice above some level of skill (e.g. with a noting frequency above 3 Hz) can be DMT-like to an extent (in light of thinking of DMT realms as made up of energized high-frequency mini-time-loops).

These experiences characterized by intense tracer effects are in a similar space as the strange temporal distortions that happen when you are dizzy (like when you stand up too fast or hyperventilate). The “loss of context” that results from this effect is due to the longest replay loops becoming too short to contain the necessary information to “keep you in the loop about what is going on”. Hence the confusion about who or what you are, what you are doing, and how you got here that happens when you are near passing out from standing up too quickly. That confusion takes place in an otherwise highly detailed and intense high-energy and high-frequency “rush” made of tiny time loops.

Thus, one of the gateways into altered states of consciousness via meditation with noting can be summarized as what happens when you induce a self-reinforcing pattern of strobing, replay, and pulsing that fully captures your attention. This process builds up a lot of energy, which one can only wield up to a point. When one fails to control it, the state decays into a series of tracer patterns that use the clean loop as its background reference. As this happens, one experiences a world whose building blocks are beautiful tiny jewels of attention, slowly decaying as one loses the ability to stay focused. The decay process also seems to do something good when properly orchestrated. Namely, as the decay process begins, one naturally experiences a Cambrian explosion of qualia critters eager to feed off of the negentropy generated, as thought-forms need attention to survive. This whole process, one could argue, lends phenomenological credence to the paradigm of neural annealing, where one’s brain uses a heating and cooling schedule to entrain brain-wide harmony.

In other words, with something like a noting practice, one ends up creating a world simulation whose building blocks are all embedded in a very tight time-loop, a wind-up universe of concentrated awareness. Perhaps we are going too far with this explanation. Either way, we really feel that thinking in terms of these generalized tracer dynamic patterns is an exciting new conceptual toolkit that allows us to describe the quality of exotic experiences that were hard to pinpoint before.

Three Exciting Possible Applications of the Tracer Tool: High-O-Meter, Synergy Quotient, and Harmonic World-Building

(1) High-O-Meter

How high are you? It is often difficult to put a number on this question. But once we have established the parameters for different drugs (e.g. characterized DMT as living in a region of the parameter-space that is of higher frequency than LSD, etc.) we can show a series of gifs to someone and ask them to point at the one that best shows what tracers looked like at the peak of their experience. This way we can quickly estimate how high they got (at least visually) with a very simple question.

For example, we may find that the “modal response” to 50, 100, 200, and 300 micrograms of LSD looks as follow:

Simulated tracer for 50 μg of LSD
Simulated tracer for 100 μg of LSD
Simulated tracer for 200 μg of LSD
Simulated tracer for 300 μg of LSD

If this works, we would be able to sort research participants into one of these ranges just by asking them to point at the image that best captures their experience. Similar tools for other modalities could be used to obtain a global “highness score” meaningful across people.

(2) Synergy Quotient (orthogonality vs. synergy vs. suppression vs. harmonization)

What happens when you combine psychoactive drugs together? We have previously discussed in great detail what happens when you take combos of drugs from various categories (see: Making Amazing Recreational Drug Cocktails), but admit that there are huge puzzles and unknowns in this space. Of note is that some combinations give rise to synergistic effects (e.g. psychedelics and dissociatives), others blunt each other’s action (e.g. agmatine and nootropics), while yet others seem to create competing effects due to some kind of mutually-exclusive qualities of experience (e.g. salvia and DMT, a.k.a. “drugfights”). For an illustrative example of the third category, famous psychonaut D. M. Turner reports:

I smoked 30 mg. of DMT in three tokes, followed immediately by 650 mcg. of Salvinorin that I had preloaded in a separate pipe.

The effects were felt almost immediately. The first thing I noticed was a grid of crosshatch patterns. I had perceived something similar when using 2C-B with mushrooms, which I believed to be the result of using two psychedelics that were not compatible with each other. However, in this case the patterns were defined to a much sharper degree, and it seemed apparent that these two substances affect consciousness in differing ways that are not synchronistic when used together. Both the Salvia and DMT entities seemed to have been taken entirely off guard and had not been expecting this confrontation. These entities seemingly paid no attention to me as their attention was entirely fixed on each other. It soon became apparent that the two were going to battle, vying to determine who would have control of my consciousness.

We think that the tracer tool can be useful to quantify the degree of interaction between two drugs. For instance, say that drug A produces a robust 10 Hz replay effect, whereas drug B produces a 7 Hz Strobing effect. Would drug A + drug B cause a tracer that blends these two facets, or does it produce something different? If the combination’s tracers are different than the sum of its parts, how large is this difference? And can this difference be identified with a particular recursive stacking of effects, or as the result of a nonlinear interaction between dynamic systems? We believe that this line of research may be very illuminating.

Drug A
Drug B
Drug A + Drug B (“orthogonal”)
Drug A + Drug B (“suppression”)
Drug A + Drug B (“synergy”)
Drug A + Drug B (“harmonization”)

In the above example, we show what various possibilities for the result of drug combos may be. “Orthogonal” effects mean that the resulting tracer is the sum of the tracers of each drug, “suppression” means that one drug’s effect reduces the effect of the other, “synergy” means that the resulting effects are stronger than you’d expect by just linearly adding the effects of each drug, and “harmonization” refers to the possible slight-retuning of the characteristic frequency of each drug’s effect that allows for a consonant blending. How strongly the combo is from the predicted effect based on each drug would determine the synergy quotient of the pair.

A few possible (tentative) examples: alcohol + psychedelics give rise to orthogonal effects, opiates and psychedelics result in effect suppression, dissociatives and psychedelics result in strong synergy (not unlike what you get when you stack reverb and looping in music), and MDMA and psychedelics might result in harmonized tracers (hence the creamy and harmonious visuals of candy-flipping). We would love to see research tackling this question.

(3) Harmonic World-Building

Tinnitus is usually loud and distracting, but in addition, it can also be annoying and unpleasant. At QRI, we posit that the precise pattern of tinnitus—not only its loudness—has implications for how bad it is for someone’s mental health: dissonant and chaotic tinnitus might be worse than consonant and harmonious patterns, for instance. 

In a similar vein, we think that the particular tracer patterns, over and above just their intensity, of perceptual conditions like HPPD probably matter for how the condition affects you at a cognitive, perceptual, and emotional level. Concretely, we would like to study how valence is related to one’s particular tracer patterns: we think that when psychedelic tracers feel good, that such positive valence may show up in the form of (a) harmonious relationships between the components of the effects, and (b) a sort of creaminness in the way the tracers come over time (as shown in the MDMA + LSD trip report by Steven Lehar).

We take seriously the possibility that something akin to the rules of harmony in music (see: Tuning Timbre Spectrum Scale by William Sethares) will have a showing in the way resonance in any experiential field cashes out into valence. In other words, the way patterns of resonance in the brain combine might be responsible for whether the experience feels good or bad. In particular, under psychedelics and other high-energy states of consciousness, one’s visual field is capable of instantiating visions of both tremendous beauty and tremendous terror. It is as if in high-energy regimes, one’s visual field acquires the capacity for creating pleasure and pain of its own (albeit “visual” in flavor!). While sober, one can get something akin to this effect, though only mildly in comparison: you can experience beautiful patterns by staring at a smooth strobe with eyes closed, or experience unpleasant reactions when the strobe shines at irregular intervals. The quality of the self-generated light-show in energized states of consciousness (such as a psychedelic experience) will likely have an impact on one’s sense of wellbeing. Is one’s inner light show all irregular, uncoordinated, sharp, and jarring? Or is it smooth, clean, robust, and soft? Based on the Symmetry Theory of Valence, one can anticipate that one’s tracer phenomenology feels good when it expresses or approximates regular geometries and bad when the implied geometries are irregular or disjointed.

Dissonant emergent pattern
Consonant emergent pattern

The creaminess of smooth ADSR envelopes would likewise prevent sensory and emotional dissonance by virtue of softening spikes of sensations. This, of course, is ultimately an empirical question. Let’s investigate it!

Final Thoughts: Getting Realms from Time-Like Textures

The complexity and information content of one’s state of consciousness as induced by a substance may depend on what fits in the repertoire of time-like textures of the state. For example, some states might be much more prone to generate quasi-crystals as opposed to crystals, as we argued in DMT vs. 5-MeO-DMT (Gomez Emilsson, 2020).

What are these crystals? One of the characteristic spatial effects of psychedelics is that they lower the symmetry detection threshold. This gives rise to the beautiful tessellations (at times Euclidean, at times hyperbolic (Gomez Emilsson, 2016)) everyone talks about. Analogously in time, psychedelics are notorious for creating time loops (cf. Going Loopy (Alexander, 2014)). In a deeper sense these are, we might argue, two facets of the same underlying effect. Namely, the creation of, for lack of a better term, qualia crystals. We can be cautious about assigning an ontological interpretation to qualia crystals; all we are proposing here is to accept them as phenomenological artifacts that tie together a lot of these experiential qualities. These gems of qualia come in many flavors, but they all express at least one symmetry in a clean and deep way. Whereas our experience of the world is usually made of a complex distribution of (tiny) qualia crystals which form the macroscopic time-like texture of our mind, we find in exotic states of consciousness the possibility of experiencing the refined, pure version. Timothy Leary in The Psychedelic Experience describes what he believes is the key existential conundrum close to the peak of an ecstatic trip:

Is it better to be part of the sugar or to taste the sugar?

Timothy Leary, Richard Alpert, and Ralph Metzner in The Psychedelic Experience

In line with the neural annealing frame (Johnson, 2019), there is a very real sense in which slightly past the peak of a psychedelic experience you will find some of the largest, purest, most refined qualia crystals (at least relative to the human norm). And what this looks like will depend a lot on what the available building blocks are! The diversity of these building blocks makes the time-like texture of experience triggered by different drugs dramatically variable. 

Some of the realms of experience are made with a time-like texture of interlocking time loops of different frequencies allowing you to experience the sense of “a big other”. In some other realms, the time loops are all aligned with each other, which makes self-other distinctions hard to represent and reason about. The various flavors for the felt sense of non-duality, for example, may correspond to different ways in which strobes, replays, pulse, etc. align perfectly to dissolve the internal boundaries used as building blocks to represent duality. At the extreme of “unification”, such as the state found in the 5-MeO-DMT breakthrough, one “becomes” a metronome whose tune is reflected faithfully everywhere in one’s experience, such that there is nothing else to interface with. Hence, one becomes “invisible to oneself”. To be in a state of near total oneness may entail the feeling of nothingness for this reason (thus the highest Jhanas being “nothingness” and “neither nothing nor something”).

This overall interpretative frame of exotic states as the result of time-like textures may show up empirically, too. One of the exciting early results, as mentioned above, is the report that while DMT creates complex positive and negative after-image dynamics full of color and polarity, the tracers on 5-MeO-DMT are monochromatic, meaning that one only experiences their positive after-image.

This alone may go a long way in explaining why the visual character of these two drugs is so distinct at their upper ranges. Namely, because DMT gives rise to complex checkerboard grid-patterns of overly-saturated colors intermingling with their polar opposites, whereas on 5-MeO-DMT, one often experiences an incredibly bright white light, or even a sense of translucid empty space, but no colors! The paradigm of using tracer patterns to make sense of states of consciousness would here suggest that a “breakthrough” experience can be interpreted as what happens when one’s world is saturated with the time-like texture characteristic of the tracer pattern of either drug. The realms of experience these agents disclose are the universes that you get when the building blocks of reality are those specific time loops and attention dynamics, leaving no room for anything that does not follow those “phenomenal time constraints”. When the dose is low, this manifests as just a gloss over one’s otherwise normal experience, a mere modifier on top of one’s sober reality. But when the dose is large, these time loops and attention dynamics drive the very way one’s mind constructs our whole sense of the world.

In this light, rather than thinking of exotic states of mind as places (as the “realm” metaphor alludes to), one can imagine conceptualizing them as ways of making sense of time. When you smoke salvia, you make sense of time in a salvia kind of way, which involves looping back chaotically in a way that typically results in losing the normal plot altogether and instead exotic narratives better fitted for the salvia attentional dynamics end up dominating the world-building process of the mind. Hence you end up in “salvia land”. Which is what you remember best. But the salvia land one ends up in is only a circumstantial part of the true story. The fundamental generator that is upstream of this realm would be the overall tracer pattern, the time-like texture of the experience: the neuroacoustic effect of salvia. He who controls the time-like texture of experience, controls the world-building process of the mind. Thus the paramount importance of understanding tracer patterns.

For Researchers

The Tracer Replication Tool is the first of a series of research tools we are creating at QRI specifically designed with psychedelic phenomenology in mind. The spirit of this enterprise is to identify the ways in which psychedelic states of consciousness can enhance the information processing of the mind in some ways. Rather than focusing on how information processing is impaired, we develop these tools with the goal of finding the ways in which it is enhanced (cf. psychedelic cryptography (Gomez Emilsson, 2015), psychedelic problem solving (Harman, 1966)). We take very seriously high-quality trips reports from rational psychonauts, which help us ideate tasks that are likely to show large effect sizes. Thus, rather than bringing traditional psychometric tools to the psychedelic space, we think that developing the tools to assess the psychedelic state in its own terms is more likely to provide novel and significant insights. We would love to have academic researchers include some of these tasks in their own study designs. Becoming familiar with the Tracer Replication Tool takes less than 10 minutes, and based on the pilot results, operating it during a psychedelic experience is possible for a good fraction of people under the influence of these substances. It would be amazing to have tracer replications included in psychedelic studies to come. If you are involved in psychedelic research and would like to use the Tracer Replication Tool or learn more about the toolkit we are developing please reach out to us! We would love to hear from you.

For Participants and Volunteers

There are several ways you can help this project. As a beta tester participant, you can use the tracer tool to replicate tracers that you yourself have experienced. There are three categories here (which you can specify at the point of submission when using the tool):

  1. Retroactively: If you have experienced visuals tracers in the past and think you can remember them accurately (or at least recognize them when you see them), you can play with the Tracer Replication Tool and submit the parameters that best match your memory of the tracers you experienced.
  2. Post-Trip: If you are planning on taking a psychedelic in the near future* and want to submit a datapoint from your experience, open the tracer tool during the trip and look at the bouncing ball (and other animations). While staring at the center of the animation for about a minute, try to get a clear picture of what the tracers look like. We encourage you to play with the color, speed, and animation type while you are in the state so that you see how tracers react to different visual inputs. Then as soon as possible after the trip is over, come back to the tool and find the tracer parameters that best replicate what you saw.
  3. Within Trip: If you are familiar with the tracer tool parameters so that you can tell in real time whether you are experiencing strobing, replays, color pulsing, etc. then you may want to try to replicate the tracers you are seeing in real time. We recognize that this has the problem that the tracer replications will have psychedelic tracers of themselves, and that they get in the way of the tracers you are trying to reproduce. That said, the early reports we have received state that it is actually easier to do a good job at replicating the tracers while in the state than after it. So we also welcome submissions of this type.

The case of HPPD and other non-drug induced tracers could be considered in this frame as well. For instance, we have been made aware that during the meditation practice of Fire Kasina, one experiences many pronounced tracers of various kinds. Thus, if you are currently experiencing meditation-induced tracers, you can submit parameters of the within trip kind. If you saw the bouncing ball (or other animations) during the meditation but have now exited your state, then you could submit a datapoint of the post-trip kind. And if you only have the recollection of tracers but did not see the ball at the time, then submit a retroactive datapoint. Likewise, HPPD and other tracer phenomena may come and go and their intensity may wax and wane, so these categories are also useful in such cases.

Please sign up to the QRI mailing list if you want to stay informed about the development of QRI’s Psychophysics Toolkit. We also want to emphasize, as we note in the Special Thanks section below, that this tool could not have been made without our amazing QRI volunteers. We are very eager to work with anyone with technical skills useful for this and related projects. If you would like to help us build these tools and advance our collective understanding of exotic states of consciousness, please get in touch.

 [1] A significant message of the book is that it is useful to conceptualize these rhythms as being the result of endogenous pattern-generating networks specialized to create specific frequencies, envelopes, and types of synchronization.

[2]  “There are only two sources that control the firing patterns of a neuron at any time: an input from outside the brain and self-organized activity. These two sources of synchronization forces often compete with each other (Cycle 9). If cognition derives from the brain, this self-organized activity is its most likely source. Ensemble synchrony of neurons should therefore reflect the combination of some selected physical features of the world and the brain’s interpretation of those features. Even if the stimulus is invariant, the brain state is not. From this perspective, the most interesting thing we can learn about the brain is how its self-generated internal states, the potential source of cognition, are brought about. Extracting the variant, that is, brain-generated features, including the temporal relation between neural assemblies and assembly members, from the invariant features evoked by the physical world might provide clues about the brain’s perspective on its environment. Yes, this is the information we routinely throw away with stimulus-locked averaging.” (Buzsáki, 2006)

In a different timeline, I open a high-class experimental qualia-focused restaurant. There is only one kind of meal every month, and it is a challenge to finish it. Only 10% of people manage to do so. On March of 2022, the menu consists of:

  1. A soup. A liter of (tap) water with a single mint leaf in it. Do not be deceived, this is not “spa water”. The amount of mint in it is exactly right below the perceptual threshold for the most discerning of tasters. Hence, you are guaranteed to (a) not be able to taste anything at all, while (b) fully knowing you are indeed drinking aromatic molecules from the mint leaf. Also, they give you a spoon and a straw. If you use the straw, you are “drinking your soup” while if you use the spoon you are “eating your soup”. Up to you. It’s a conceptual piece after all. Once -and only once- you finish it, they serve you the second course…
  2. There are aromas and flavors out there in the state-space of qualia-triggering molecules that cancel each other out perfectly. The second course consists of a series of small hors d’oeuvres that are completely tasteless. If you can taste anything- e.g. a hint of garlic, or orange- it means the chef didn’t prepare it well. The flavors need to be perfectly balanced for them to be entirely tasteless. And once you are done, they bring you…
  3. This thing they left on your table is akin to a wire puzzle, or one of those Hanayama pieces. They tell you that your third course consists of a tiny cookie hidden inside it. Average solving time: 25 minutes. 50% of people can’t solve it.
  4. You are given a miniature 3D printed sugar statue reconstruction of someone who shares your name (as close as possible). Before eating it, you have to scream “There can be only one!” and consume your namesake in a single bite.
  5. Trace minerals. They bring you this large metallic bowl with a tiny little bit of powder at the bottom; certainly no more than 50 or 60 milligrams of material. It contains half of your daily recommended dose of iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium. You can now finally know what these actually taste like. It turns out that the characteristic taste of your grandma’s famous tapioca dish was zinc. Moving on…
  6. Negative food. You donate 300ml of blood.
  7. Distilled saliva. You spit in a bowl a number of times. You are then given a little shot of perfectly tasteless and clean water. The water is chemically pure. However, it is the water in the saliva of the spit of another customer.
  8. Double blind taste experiment. You are given a dish. The waiters do not know what it is. You do not know what it is. You have to write a 100-word report of what you think about this dish. This is actual science; the data is used by a research lab at some undisclosed university. There is something very Buddhist about this course – how much does your top-down model of what you are eating modify your perception of it? What if you do not assume an “essence” behind it – block that specific energy sink from robbing you of the experience of raw low-level sensation?
  9. Sound control. Did you know that food tastes different in an airplane? Many factors contribute to this, but a major one is the constant background noise you can hear inside the aircraft. Turns out tastes change with specific sounds. The Qualia restaurant spent $500,000 dollars researching this (and publishing a number of peer-reviewed papers in the process). The output of that research is that you can now make chocolate taste like vanilla, and strawberry taste like melon – if only you play the proper sound at the right volume. And finally…
  10. Stroboscopic taste – you put on a mouthpiece that entrains half of your tongue to a 30Hz electric seizure vibration while the other half is entrained to 17Hz. As you eat the Ice-cream of Victory (flavored with passionfruit, peanut, and anise) you realize that the flavors combine with the stroboscopic stimulation to create the hallucination of an entire meal replete with much more complex flavors. The beat patterns are tasty.

If you finish the entire thing (which usually takes about 5 hours total) they take a photograph of you and “keep it to themselves”. No, there is no “victory board”. They just want a picture of you.

Favorite essential oils at the moment: Freesia, Violet, and Pear. It turns out Freesia was a predominant note in Dior “Addict 2“, a perfume I fell in love with when I was a teen. Violet is “ethereal” in that it feels strangely anesthetizing (the ketamine of smells). Pear is lovely.

High Entropy Alloys (HEAs) and Scents:

  1. Some scent combinations “collapse categories” (e.g. too many flowers combined blend into “generic flowery”).
  2. Others make unstable multi-phase blends (e.g. too many categories – spicy, citrus, minty, woody all at once).
  3. Violet + Pear create a scent HEA.

An interesting blend with “emergent” characteristics: Freesia, Pear, Violet, Sunflower, Azalea, and Patchouli. Very high valence mixture that has a novel feeling that does not seem to come from the ingredients. #HighEntropyAlloy #HighEntropyScent

January 8th 2020

Careful with raising the “scent entropy” too high!

In sound and sight, it seems that there is an inverted U curve relationship between stimuli entropy and the entropy of the experiential response. White noise may be- objectively- the way to cram in as much information as possible into a waveform. But perceptually, white noise is more like its own (neutral valence, indifferent) tone. Likewise visually, if you crowd your images way too much you can’t actually understand its meaning and true complexity. Perceptual complexity response is maximized in the middle, where you achieve “peak useful entropy”.

More so, extremely entropic stimuli can be used to “mask” any input by adding a dose of white noise or visual static. That’s how you can degrade the valence of something when you don’t know what kind of unpleasant input you will get in advance. White noise drowns out both construction sounds and baby screams. It’s a “universal diluter”, so to speak.

And so it seems that this is the case with smells too. If you combine any 40 (42?) scented molecules that are as different as possible, you get as a result a generic smell with neutral valence that is not distinctive at all. If you make a different 40-scent mixture with completely different molecules, it also smells the same! They call it white noise scent, or “Laurax”*.

In other words, the “high-entropy alloys” of smell may only really pay off in the range of 5 to 15 different molecules, where (perhaps) we maximize the experiential “character” of the resulting fragrance.

Now, of course commercial perfumes in practice do have dozens if not hundreds of aromachemicals. But their absolute “scent entropy” is probably not that high. Why? First, the entropy is reduced by the fact that most perfumes do concentrate on a few core notes; the many other notes are usually small additions and tweaks. And second, the perfumes are usually made with relatively few categories of smells blended together (musky, citrus, and flower could be one, or green, ozonic, and non-citrus fruity another, and so on). Additionally, to get true white noise smell you need to also add negatively valenced scents, which are rarely used in actual perfumes. I do wonder, though, if the perfume industry has a sense of the “scent entropy” of their various perfumes, and if having a measure of it would perhaps improve their ability to hone in on blends that have unique emergent characters without relying entirely on heuristics and trial and error. Or how about a portable “scent-entropy-o-meter”? I bet it would find some very useful applications.

[Good article about it: The “white noise” of smells; *I first learned about Laurax here: The whiff of white could hide strong odours: Complex mixtures of many odours tend to smell the same.].

January 10th 2020

Of all the industries, I get the impression that the perfume industry is ahead of the curve when it comes to incorporating hedonistic utilitarian notes into its embedded ideology.

Cilantro tasting like soap to 10% of the population is just the tip of the iceberg.


January 13th 2020

What are your favorite perfumes?
(and if it’s not impossible to describe – why do you like them so much?)

I’ll start:

Addict 2 by Dior
Eros pur femme by Versace
Light Blue by Dolce & Gabbana

Oh god, what kind of person have I become?

January 14th 2020

Scent combinations with unusual emergent characters that are “more than the sum of their parts” I have discovered so far:

  1. Violet + Pear
  2. Rose + Orange
  3. Honeydew Melon + Pomegranate
  4. Freesia + Golden Hydrangea

In each of these cases, combining in roughly equivalent intensities (i.e. 50-50 ‘equipotent’ mixtures) seems to give rise to qualities that are not present in either of the two scents. This is relatively rare, IMO. If you combine, e.g. lilac and jasmine, you just get something that smells like “lilac and jasmine”. But the four combinations above seem- to me- to give rise to new exotic qualia varieties.

An accord is more about getting rid of the individually distinguishable component scents. The end result, however, is one of a “generic” scent within a given category (or subcategory). For example “white flower accord” or “citrus accord” are common. And although you can distinguish between two citrus accords, they don’t really have unique character – at least not more than e.g. various kinds of brown noise have a unique character. The combinations I’m mentioning are not just ways of creating a category blend so that other elements of the perfume can be more noticeable. Rather, they are on their own uniquely characteristic, much like other pure essential oils.

If you mix a wide enough variety of flowers you inevitably get a flower accord. To get a new qualia type emergent you need something else. (I should add I’m new to the field and have a lot to learn).

I’m developing a way of explaining what a scent is like at a glance with relatively few parameters. One of them is category entropy, meaning how close a given category in the scent is to the maximally blended version of it (i.e. a fully generic “flowery” scent has maximum category entropy).

Then another parameter is the “global entropy” which describes how close the scent is to total white noise scent.

So we start by saying e.g. perfume X is “50% of the way to white noise scent and its distribution of core categories is 30% woody, 30% floral, 20% fruity, and 20% citrus”, then we zoom in to each category and describe its category entropy and salient notes: “the floral entropy is 40%, and the 60% remaining is shared in equal measure between rose and azalea” (repeat for each category).

Additionally, another important thing to add is if there are “note to note interactions”, which in my (limited) experience happens with some pairs. Maybe 10% of them, but I don’t know for sure. But you could describe them with lines between individual notes in a diagram. To round it all out, you also would point out the note accords that work as “phases” in the overall scent (drawing inspiration from high entropy alloys – an alloy that does not make a single crystal structure is called “multiphasic”). E.g. mango + patchouli + cinnamon + jasmine tends to produce two phases, a mango + cinnamon phase that toggles in your attention with the jasmine + patchouli phase. Finally, we would also note “valence inversion” effects that happen when there are combos of scents that when placed together give rise to a flipped valence (also a rare effect, IME).

For a slightly higher level of resolution, we would break down each category into subcategories and then describe the entropy of each. E.g. a floral perfume could be 80% of the way to maximum floral entropy in the “white flower” subcategory but only 10% of the way to maximum entropy in the “powdery flower” category.

This would allow us, I think, to put our finger on many scents that are hard to describe otherwise. Indeed, a lot of sophisticated perfumes, IMO, are playing a lot with different shades of high entropy, so talking about them in terms of notes like jasmine or amber is very misleading. It’s like calling a certain kind of brown noise “closest to a guitar sound” because one lacks words for describing noise profiles.

January 23rd 2020

Scent Factorization:

So we know that we can get “white noise smell” by combining 42 scents of completely different kinds at the same time. This maxes out the “scent entropy” (aka. “Laurax”).
If you combine 42 different flower scents, however, you get a maximally generic “flowery scent”. I call this “category collapse”.

Now some scents have what I call “special effects”, which are category-neutral qualities. An example is the ‘bitterness’ of grapefruit, which although is often associated with fruits, can occur in entirely different categories too.

So I thought: what if we try to combine scents from as many categories as possible that all share the same special effects? I call this “scent factorization”. Namely, you try to get “special effect + Laurax” by canceling out everything but the special effect.

I believe this actually works. Example:

A factorization of “bitter-sweetness” can be obtained by mixing:

Grapefruit + Geranium + Bergamot + Pomegranate + Cedar-wood

In this case you will see that geranium is almost like “the grapefruit of flowers” in that it is flowery in nature but still shares the same “bitter” quality as grapefruit (albeit at a different frequency – yes scent frequencies are a thing, but that’s a story for another time). Likewise, cedar-wood is the most grapefruit-like wood I’ve smelled.

Another interesting factorization is that of “creaminess”:

Coconut + Fig + Vanilla + Almond + Sandalwood

In this case, again, you’ll see that sandalwood is the most “creamy” of all woods (as far as I have tried), fig is the most creamy of all fruits, and so on.

But this is just the start. What other scent factorizations could we try? I’d say we could aim to have the special effects of “ozonic”, “green”, “ethereal”, “powdery”, “acrid”, “cloying”, and so on factorized. Each deserves to become its own perfume in my up and coming new line of high end perfumes called “The State-Space of Scents” (for the consciousness connoisseur).

The Qualia Review – Episode 1: Women’s Perfumes (Part 1):

The Qualia Review – Episode 1: Women’s Perfumes (Part 2)

The Qualia Review is a tongue-in-cheek program where you will get non-expert opinions about the quality of experiences by people who really care about consciousness:

In each episode, Andrés Gómez Emilsson (qualiacomputing.com) reviews a particular qualia variety (i.e. category of experience) with a co-host (in this episode Victor Ochikubo).

In this first episode we review women’s perfumes. In particular, we review (from worst to best):

La Panthére by Cartiere (EDT)
By Invitation by Michael Bublé (EDP)
Guilty by Gucci (EDT)
Brit Rhythm by Burberry (EDT)
Jolie Fleur Bleue by Tory Burch (EDP)
Rose Goldea by Bvlgari (EDP)
Daisy Love by Marc Jacobs (EDT)
Valentino by Valentino (EDP)
Amazing Grace Ballet Rose by Philosophy (EDT)
Light Blue by Dolce & Gabbana (EDT)
Eros by Versace (EDT)

You will notice that this is unlike any other review of perfumes. This is because the review here provided addresses the following three aspects of scents:

  1. A qualia-focused account (i.e. entropy, categories, special effects, etc.)
  2. What kind of person would enjoy wearing this perfume (mood-congruence, personality, etc.)
  3. The social signaling that the perfume entails (sexual signaling, genetic fitness signaling, etc.)

In particular, (1) describes scents in terms of:

  • A) The global entropy (e.g. 40% of the way to white noise scent)
  • B) The within-category entropy (e.g. 70% of the way into ‘generic flowery’)
  • C) The individual notes that can be detected within each category (e.g. non-generic jasmine note being 30% of the flowery category)
  • D) Lines connecting notes that have non-linear interactions (e.g. pear & violet, rose & orange, pomegranate & honeydew make unique blends that have phenomenal properties unlike those of the individual ingredients)
  • E) Lines connecting notes that form separate “phases” across categories (e.g. with a mixture of mango, sandalwood, rose, lemon, and cinnamon you get three phases rather than a global consistent smell – mango + cinnamon, and lemon + sandalwood, with rose staying its own distinct scent)
  • F) Lines connecting “valence inversion” effects (some notes simply don’t seem to go together even though they are pleasant individually)
  • G) Special effects (e.g. “powdery”, “ethereal”, “acrid”, “creamy”, etc.)

Thus, we share an entirely new angle on how to describe the ineffable. Namely, the hard-to-put-your-finger-on elusive subjective quality of scents can finally be grounded in terms we can all understand (with a modicum of shared background assumptions).

Hope you enjoy! Happy scent qualia!

Three scents that are surprisingly similar to strawberry (based on my personal experience with essential oils):

  1. Fig
  2. Freesia
  3. Peony

In fact, following the “scent factorization” concept – if you make a mixture of these three scents the resulting oil smells almost exactly like strawberry cake. Strange!

I love this video! The idea that the information content in a perfume could possibly fit so much phenomenal detail is enticing, albeit perhaps a bit optimistic.

In the interest of honesty, out of the 15 or so women’s perfumes I’ve experienced deeply so far, La Panthere by Cartier is the worst by quite a long shot.

I don’t mean this to troll! I am serious. I still don’t quite know why I feel it as so unpleasant. I think it has to do with its very high entropy quotient, and the fact that it centers around gardenia, which is my least favorite flower. It feels predatory – and perhaps the perfumist did succeed at telling a story. Too bad I aim to reprogram the biosphere so that predation is a long-forgotten nightmare of our ancestral Darwinian environment of adaptedness. So long! We should aim to transform scent exploration from its current state of commercialism mixed in with weapons of sexual conquest, and push it into new frontiers… the exploration of the state-space of consciousness, valence research, perhaps even energy parameter modulation! The future of scent qualia research is wide open.

The Qualia Review – Episode 2: Men’s Perfumes

The Qualia Review is a tongue-in-cheek program where you will get non-expert opinions about the quality of experiences by people who really care about consciousness:

In each episode, Andrés Gómez Emilsson (qualiacomputing.com) reviews a particular qualia variety (i.e. category of experience) with a co-host (in this episode Victor Ochikubo).

In this second episode we review men’s perfumes. In particular, we review (by order of appearance):

CK2 by Calvin Klein (EDT)
Pasha de Cartier Edition Noir by Cartier (EDT)
Virtu by Vince Camuto (EDT)
21 Le Fou by Dolce & Gabbana (EDT)
Le Male by Jean Paul Gaultier (EDT)
Scuderia Ferrari Light Essence Bright by Ferrari (EDT)
Jimmy Choo Man Blue by Jimmy Choo (EDT)
1 Million by Paco Rabanne (EDT)
Terre D’Hermes by Hermes (EDT)
Invictus by Paco Rabanne (EDT)
Bleu De Chanel by Chanel (EDP)

In this episode we also discuss the way in which an enriched conception of art could helps us reformulate the artistic potential of perfumes. We make allusions to the 8 models of art discussed in a previous video:

It’s very sad that there is a huge paywall for scent qualia. It’s your birthright to know what they smell like!

February 11th 202084357695_2785896804835792_4296261472725499904_o

~120 essential oils and ~40 perfumes (ordered by categories and general character).

This is the dataset my brain has been training over to interpret the state-space of scent qualia for the last month and a half. This is still amateur level – but I can nonetheless confidently say that I now understand scent qualia at least 50% better than I did last year.

I would still appreciate specific suggestions for essential oils or perfumes to get that are very unusual or characteristic. I continue to be surprised by the uniqueness of oils, fragrances, and mixtures I haven’t tried before.

Also: drastic income inequality is a massive tragedy, no doubt. But why are people not talking about qualia inequality? I wish everyone was as qualia-rich as I am right now. I’m happy to share some scents with people who feel qualia-deprived; just come to the Bay and give me a call. 🙂

Ps. Peony is an incredibly versatile low-entropy flower scent with a creamy strawberry-like effect. I kept reading about how this or that perfume has peony in it, but it really took me owning an essential oil of it to grok the type of qualia peony is all about. Someday there will be a monument built to celebrate the qualia variety disclosed by peony formulas. I’m pretty sure of this.

People say “a blind buy” when they talk of buying a perfume they haven’t smelled. Shouldn’t it be more appropriate to say an “anosmic buy”?

February 18th 2020

In order to survive the apocalypse, having a “blue” fragrance on hand will become very useful. I suggest “Nautica Voyage“.

Sense of Smell is Linked to Sexual Orientation, Study Reveals

Very interesting! Two followup questions: (1) does it replicate on a larger sample size? and (2) is the baserate of different sexual orientations of anosmic people statistically different than those of the general population?

Gay men showed a strong preference for the body odour of other gay men in the scientific test of how the natural scent of someone’s body can contribute to the choice of a partner.


Although previous studies have shown that body odour plays a role in making heterosexual men or women attractive to members of the opposite sex, this is the first study that has investigated its role in sexual orientation. Charles Wysocki of the Monell Chemical Senses Centre in Philadelphia, a non-profit research institute, said the findings underline the importance of natural odours in determining a sexual partner whatever the sexual orientation of the person involved.


“Our findings support the contention that gender preference has a biological component that is reflected in both the production of different body odours and in the perception of and response to body odours,” Dr Wysocki said.

February 27th 2020

Jasmine, Tuberose, and Gardenia: the Dark Triad of White Flowers. Beware! They are treacherous, envious, and guileful. DO NOT TRUST. They will ruin your perfume with their high-entropy indolic ‘broad spectrum scent noise’. Deranged, distracting, and disingenuous. #FlowerProblems

Why you should not insufflate ketamine: (1) it can irreversibly damage your bladder and cause very serious untreatable chronic pain, (2) it can damage your liver, also very painful, but above all (3) it will slowly degrade your ability to experience scents! Not worth it IMO!

Cocaine is well known for causing anosmia in regular users. I suspect we are going to see a wave of anosmic people as ketamine becomes more popular. Don’t be a victim. “Remember kids, don’t insufflate drugs – either eat them or inject them” would be my DARE go-to phrase.

There’s An Unexpected Loss Of Smell And Taste In Coronavirus Patients

Factoring in the loss of precious qualia would make this epidemic even worse. This year I’ve finally begun appreciating the state-space of scents. I’m heartbroken to learn about this effect. So much qualia in potentia that might be lost!

March 23rd 2020

We should emphasize the possibly of life-long loss of smell in order to get more young adults onboard with strict social distancing measures. A 20-something person might not fear a fever, but they may fear “having less sexy sex and enjoying food less for the rest of their lives”.

Sense of smell over the years. People under 40: please do yourself a favor and get some nice scents so you enjoy them while you are still sensitive to them. It’s always a tragedy not to use a qualia variety and then lose it. #qualia #scent #aging #valence #bliss #WeAreTheQualia

This is the future – in 2010 I was saying that in the long run humanity will need to adopt entirely new and seemingly extreme measures against contagious diseases.

Nasal filters (aka. “nose condoms”) were one of the ideas I was considering at the time. Reality is now catching up with fiction.

Why adopt extreme measures? Because we haven’t seen anything yet. The possibility of rational virus design and the political will to invest in innovative weapons means that sooner or later we will encounter things with a case fatality rate > 80% and R0 > 4. Nothing short of large-scale contact network engineering and the widespread use of tech like nasal filters can really work against those long-tail risks.

Perhaps in the future going out without nasal filters will be considered as reckless as today it’s considered having unprotected sex with a random stranger. #NasalFilter #TheNewMask #PM2point5

Bright Neroli

Summer 2020 Unisex Perfume Recommendations:

1. Bright Neroli – Ferrari (amazing sharpness and cute Sicilian dry-down)

2. Monserrat – Bruno Fazzolari (incredible grapefruit punch and bitter-sweet resonance)

3. Born – Adidas (a cheap but highly rewarding lavender rhubarb scent).

April 21st 2020

Haven’t posted about scents in a while; I’m still actively researching this fascinating qualia variety (better do so while I still have scent qualia, which may of course go away if/when I acquire COVID-19).

I’ve developed a lot of new vocabulary to talk about scents. In particular, I like to break down a scent in terms of entropy (how close to ‘white noise scent’ it is), category distribution (% woody, citric, fruity, etc.), category-specific entropy (e.g. 70% of the way to ‘generic flowery’), specific notes (e.g. 10% rose), and of course, “special effects” (such as “creamy”, “powdery”, “bitter”, etc.).

A recent “special effect” I’ve explored is the rather peculiar feeling that the scent is “flammable”. For example, gasoline has it, and so does ethanol. It is similar to the feeling you get when you inhale nitrous oxide. A kind of fascinating gas-like intoxicated state that produces spatiotemporal confusion and a sense of resonance. Of the scents I currently have access to, 100% pure Neroli essential oil strongly triggers this particular special effect. Neroli has that strange “flammable” quality, perhaps an octave or two in pitch higher relative to gasoline. It’s equally enthralling as the smell of gasoline (for those who like it) but much more dinner-party-friendly.

Anyway, with this “flammable” special effect in mind, I’ve been exploring what can be added to it in order to create beautiful scents. Last night I found a combination that made me really happy. It consists of equal (intensity-adjusted) parts of:

  1. Neroli oil
  2. Orange essential oil
  3. Lime essential oil
  4. Pear essential oil

It is sweet, sour, and gasoline-like in an unexpectedly euphoric way. I highly recommend this quale. I very much like its vibe. Meet me there.

April 28th 2020



First I tried essential oils. Then I tried perfumes. Now I’m entering a third phase in my “scent literacy” journey: pure molecules.

I have 50 pure perfume ingredients in an air-tight container now. And I have been trying out a couple each day in a systematic way in order to map out the state-space of scents.
One core insight so far:

Essential oils are extremely rough approximations for “building blocks” of scents. Perfume notes are often described in terms of fruits, woods, flowers, animalic sources, etc. But “apple” is not a natural unit of scent qualia. Although there is a general “apple vibe”, in reality that vibe can come from any of 20 or so different molecules. Additionally, many molecules that have an apple vibe do not even appear in biological apples (and vice versa). I’ve so far tried two apple-vibe molecules:

  1. Alpha Damascone: The smell of a dried out green apple, slightly past its prime, unsweetened and with trace amounts of beeswax wrapper stuck to its skin.
  2. 5-octen-1-ol: The smell of extremely mild refrigerated apple sauce, slightly waxy, reminiscent of sandalwood, and at a slightly higher “phenomenal frequency” than damascone.

In other words, I’m learning that pure molecules are indeed more “simple” than essential oils by far. They feel very specific and low-dimensional rather than voluptuous and scenic. But despite their relative simplicity, they are still not “categorically pure”. A single molecule can smell woody, fruity, and camphorous all at the same time. Part of the story is likely that a single molecule can have a broad spectrum of receptor affinities. But even if only one scent receptor were to be activated, perhaps the resulting experience would also not be uni-categorical.

The fascinating implication here is that scents that feel very uni-categorical (e.g. pear essential oil being unequivocally “fruity” with no hint of floral or woody) are more likely to be compositions of many molecules!

Each uni-categorical accord is made by mixing many molecules that all share the same “main vibe” but have different “secondary traits”. This way the accord lets the secondary traits “cancel out in white noise scent” while the main vibe is additively compounded into a broad-spectrum power-punch of a single category, like fruity (reminiscent of “scent factorization”, which I’ve described in previous posts).

The Perfect Scent excerpt:

Ellena will dip a touche into a molecule called isobutyl phenylacetate, which smells vaguely chemical and nothing else, and another into a synthetic molecule whose common chemical name is ethyl vanillin. (A rich gourmandy vanilla molecule, its IUPAC name is 3-methoxy-4-hydroxy benzaldehyde, and it is the heart of Shalimar.) He puts the touches together and hands them to you. Chocolate appears in the air. “My métier is to find shortcuts to express as strongly as possible a smell. For chocolate, nature uses 800 molecules, minimum. I use two.” He hands you four touches, vanillin + natural essences of cinnamon, orange, and lime—each of these has the full olfactory range of the original material—and you smell an utterly realistic Coca-Cola. “With me,” says Ellena, “one plus one equals three. When I add two things, you get much more than two things.”


He will hand you a touche that he has sprayed with a molecule called nonenol cis-6, which by itself smells of honeydew melon or fresh water from a stream. He’ll then hand you a second touche with a natural lemon on it, direct you to hold them together now, and suddenly before you appears an olfactory hologram of an absolutely mesmerizing lemon sorbet.


The explicit point was not to create a thing but an illusion of that thing, an olfactory alchemy. The point of Nil was not to create a green mango but the illusion of a green mango.




Junior perfumers discover that Vetiver Huile Essentielle from Haiti smells like a Third World dirt floor and Vetiver Bourbon from Isle de la Réunion smells like a Third World dirt floor with cigar butts. (They hope to do something wonderful with the cigar butts.) They learn, as Ellena knew from decades of work, how to create the illusion of the scent of freesia with two simple molecules, both synthetics: ionone beta + linalool. And orange blossom: linalool + anthranylate de methyl, which by itself smells like aspirin. The classic Guerlain perfumes often used a molecule called styrex, which smells of olive oil pooled on a table in a chemical factory. Add phenylethylic alcohol and you get lilac. Add the smell of corpse (indoles), you get a much richer lilac. And you can give your lilac, freesia, and orange blossom a variety of metallic edges: Add allyl amyl glycolate, you get a cold metal freesia. Add amyl salycilate, and you get a freesia with the smell of a metal kitchen sink dusted with Ajax powder. Aldehyde C-12 lauric adds an iron with a bit of starch still on it.

Excerpt from Luca Turin and Tania Sanchez’s 2008 perfume guide:

Sports Fragrances:


The last decade has seen the unfortunate flourishing of a dismal genre, the fragrances for men and women who do not like fragrance and suspect that none of their friends do either. The result has been a slew of apologetic, bloodless, gray, whippet-like, shivering little things that are probably impossible, and certainly pointless, to tell apart. All fragrances whose name involves the words energy, blue, sport, turbo, fresh, or acier in any order or combination belong to this genre. This is stuff for the generic guy wishing to meet a generic girl to have generic offspring. It has nothing to do with any other pleasure than that of merging with the crowd. My fondest hope is everyone will stop buying them and the genre will perish. Just say no.


Lastly, and by way of contrast, remember that perfume is foremost a luxury, among the cheapest, comparable to a taxi ride or a glass of bubbly in its power to lift the mood without causing subsidence the morning after. Wear it for yourself.

The Rainbow God Experience

One of the most interesting lines of evidence pointing in the direction of the Symmetry Theory of Valence is how in the neighborhood of the peak of high-energy neural annealing events one can often glimpse states of consciousness with a characteristic “full-spectrum of qualia” property.

This may happen nearing the peak of a strong LSD trip, during intense Jhanic concentration, Fire Kasina practice, or even just spontaneously (though extremely rarely).

At the actual peak of the annealing process you are likely to arrive at a “moment of eternity“- itself extremely high-valence- where the symmetry is so complete that it becomes impossible to distinguish between self and other, before and after, or even left and right (this is a phenomenal property of peak valence states, and not proof of Open Individualism and non-duality per se, even though most people tend to interpret such experiences that way).

The “Rainbow God” phenomena lives at the edge of such peak valence states.

Timothy Leary in “The Psychedelic Experience” says that as you approach the highest bardo you are given the choice between “tasting sugar” and “being the sugar”.

The former is close to the peak of the annealing process, where there is enough asymmetry in the state for you to be able to encode information and distinguish between past and future, self and other, etc. and thus able to experience a projective world-simulation and the illusion of a self that “experiences it”. At the top of the annealing process, however, the extreme symmetry does not allow you to do that. The valence is almost certainly higher, though the degree of consciousness is arguably lower. You are “the sugar” rather than “tasting the sugar” (i.e. you are luminosity rather than a constructed world-simulation “experiencing luminosity”).

Stunningly, this edge between perfect symmetry and its surroundings in configuration space often shows extreme levels of qualia diversity. This is an empirical observation you can verify for yourself (or you can trust me, find others who have experienced it, or derive it from first principles).

What is it like? At this boundary between quasi-perfect symmetry and perfect symmetry you experience rainbows with all the phenomenal colors in the CIELAB color space (and perhaps some other colors that you only see in heaven, like blue-yellow and red-green, which require enough energy to overcome the lateral-inhibition opponent process going on in the cortex at all other times). You experience a sense of “all possible temporalities”. A sense of “all possible scents”. And a sense of all possible spatial relationships at once.
If you get any closer to the peak of annealing, the rainbows collapse into luminosity, the scents into a sense of presence, the temporalities into a sense of eternal now, and the possible feelings of space into a projective-less “view from nowhere”. The combination of all qualia values of each qualia variety somehow, incredibly, seem to add to zero. But not any kind of zero. A special “Zero” perhaps equivalent to “no information but awake”. (Cf. David Pearce’s Zero Ontology for a possible grounding of this state in fundamental physics.)

Yes, this is very much a real state of consciousness. It is profound, and extremely important.

I call it the “Rainbow God” state of mind. I do not know how to reliably induce it, but I do know that it is likely to have extremely deep computational, ethical, and experiential properties capable of advancing our understanding of the nature of the state-space of consciousness. I just figured you should know this exists.

Andreas Keller • Olfaction and Experiential Authenticity:scent_presentation

Really excellent presentation about the biological and physical underpinnings of scent. It’s a bit on the long end (50 minutes) but you can get 80% of it by just watching the first 12 minutes. It’s really good! So much information…

For instance: did you know there are about 400,000 scented flower species in the world? I struggle to come up with more than 30 flowers off the top of my head (up from 5 just less than a year ago). The remaining 399,970? Who knows what they smell like. We don’t have words for these smells… is it “rose” or “jasmine” smell? Good luck using that kind of ontology describing the space of possible flower smells.

Also: it turns out that volatile molecules don’t diffuse very effectively. So that’s why you get “whiffs” of scents – for the most part, in the wild, air is a very non-homogeneous gas, with all kinds of pockets with specific linear combinations of aromachemicals. Hence why holding two essential oils side by side doesn’t give rise to a proper mixture between them. You need to literally mix the oils and then smell the mixed result if you want to actually know what the combination is like. Otherwise you will get a whiff of one, a whiff of the other, etc. with a Poisson-like distribution. This also reminds me that: we have an olfactory bulb in each nostril! So if you apply one scent in one nostril and another scent in the other nostril, you will get a kind of “bi-scent rivalry” [binosmic?] similar to what you get when you see one image with the left eye and one image with the right eye (i.e. “binocular rivalry”).

I do think that “digital smell” is possible (unlike the presenter). But it will require us to describe each molecule in terms of their ADSR patterns for each of the basic scent qualities (that is, to describe how the sweetness develops across time – its attack, decay, sustain, and release – and do the same for each core qualia scent dimension). Without taking into account the ADSR envelope for each molecule, the mixtures will be uneven.

The lowest-hanging fruit would be to use a non-negative least squares regression that minimizes the error for the envelope of each of the core qualia scent dimensions. Hence, the molecular spectrum is not enough – the non-negative least squares requires pattern-matching across the entire temporal envelope of each dimension. IF we do this – then digital smells might be possible after all (IMO!).

There are a TON of questions whose real answer is: “Bleu De Chanel”. Think about it.

That’s how VAST the multiverse is.

“Bleu De Chanel” spans eons and eons of subjective time – the grapefruit/incense/amber vibe ringing on and on throughout eternity. That’s how large it ALL is.


You can get a powerfully believable Smirnoff Lime impression with as little as a few drops of citral and aldehyde C-12 in an ethanol + water mixture. Amazing what passes as a “fine drink” these days.

“At least add some linalool to make it worth it” – would be my recommendation.


Note to self: by virtue of their sharp smell, aldehydes are powerful high-frequency psychoactives.

June 6th 2020

Note to self: Smelling a bunch of aldehydes over and over for several days in a row causes bad headaches. Use them only occasionally from now on.

I asked a DMT being about the nature of scent qualia. Its response: “One hint: are you sure it’s only one kind of qualia?”

An insight came like a lightning bolt. Yes! Two types:

  1. Aromachemicals that are “character impact”
  2. Flavor-like vibes

Totally different state-spaces!

Luca Turin, the quantum neurobiologist who has done research on the vibration theory of olfaction (showing “we can smell functional groups”) told me that if perfumes are tomato soups, the money is in “making the best cream” rather than in the “tomatoes”. Character impact!

Examples of character impact molecules:

  1. Beta-ionone
  2. Iso-E-Super
  3. Ambroxan
  4. Hedione
  5. Helional

Examples of flavor-like vibe molecules:

  1. Alpha-damascone (beautiful!)
  2. Aldehyde C-12
  3. Citral
  4. Cis-3-hexanyl-benxoate (yuk!)
  5. Verdalia

Magenta: The Non-Spectral Color

An important point of confusion about qualia to which I offer a clarification:

The qualia you experience as a result of light coming into your eyes can be logically and empirically dissociated from physical light. Color qualia, just as much as visual texture qualia, can be triggered by auditory stimuli in people with synesthesia, or people tripping. More so, you don’t even need light to ‘see’ in your dreams. Visual qualia is ultimately not intrinsically tied to physical light. Phenomenal light, as it were, is a particular spatial qualia that we use to ‘illuminate’ our inner world simulations. Yet this illumination is not based on photons.

Hence the mystery of magenta: phenomenal colors don’t always map on to frequencies of light. Even leaving aside the issue of metamerism, magenta itself is a ‘non-spectral color’ because you need to combine at minimum two frequencies of light to trigger that color qualia in your visual field (namely, a combination of the upper and lower frequencies you can detect).

Why do we experience color qualia from light, then? This is not out of logical necessity, but rather, because it happens to have the appropriate information processing properties for the mapping to be evolutionarily advantageous. The state-space of color and visual texture happen to have useful isomorphisms to the structure of visual data. But there is nothing to suggest they are the best at representing ‘projective data-structures’.

In fact, I strongly suspect that once we master free-wheeling hallucinations and qualia control techniques, we will discover new applications of exotic qualia varieties for information processing purposes. Such as, for instance, using complex synesthetic representations of natural numbers that make it easy to ‘feel’ whether a 10-digit number is prime or not.

Anyhow, this all informs the kind of answer I might give to the question “what is it like to be a bat?”. In particular, it compels me to say that for all we know echolocation information is represented with scent qualia. We simply don’t know enough about the information-theoretic properties of state-spaces of qualia varieties to make an educated guess for what kind of qualia is best at representing echolocation information.

And more so, even if you were to train a human to use echolocation from birth, there is no guarantee that the qualia varieties and the associated state-spaces their brain would recruit for that task would have anything to do with bat echolocation qualia. So the problem has more moving parts than is usually assumed.

“Son, there is something I’ve been meaning to tell you for a long time, but only now I’m brave enough to do so: I just don’t think aromatic Fougères are a good fit for you. Based on my experience, I think Chypres would fit you better. Or even some woody citruses. Not Fougères.”

Vimalakīrti then asked the bodhisattvas from the Host of Fragrances [world], “How does Accumulation of Fragrances Tathāgata explain the Dharma?”


Those bodhisattvas said, “In our land the Tathāgata* explains [the Dharma] without words. He simply uses the host of fragrances to make the gods and humans enter into the practice of the Vinaya. The bodhisattvas each sit beneath fragrant trees, smelling such wondrous fragrances, from which they attain the ‘samādhi of the repository of all virtues.’ Those who attain this samādhi all become replete in the merits of the bodhisattva.”

July 30th 2020

Emergent scents – when you combine two or more aromachemical cocktails and you get as a result a scent that is different than the sum of its parts.

I have in the past found a number of essential oil combinations that do this (pear + violet, pomegranate + honeydew, lemon + lavender). But I figured that it’s much better to try to identify clear cases of this phenomenon by combining pure molecules.

So this little “research program” I have going on is to find pairs of aromachemicals and then mix them in many different ratios and smell the results (usually dissolved in ethanol at a concentration of ~20%). So far, it seems that about ~25% of pairs of molecules I’ve tried result in emergent scents. Here are some specific examples (please feel free to try at home and verify!!):

1) Humulene + d-limonene: Humulene smells herbal and earthy, d-limonene smells like orange or mandarin. When the ratio is ~4:1 I get an emergent scent that I can only describe as “classic chewing gum flavor”, completely distinct and phenomenally richer than the ingredients alone.

2) Linalool + beta-ionone: linalool smells like a very gasoline-like volatile version of a flower scent, beta-ionone is the classic “violet scent” molecule. When combined in 9:1 ratio I get an emergent scent that is like that of a citrus version of freesia or peony.

3) Humulene + vanillin: vanillin is the smell of vanilla, which is watery at the onset (attack and decay) and creamy on the second half (sustain and release). When combined in 1:1 ratio you get a completely new scent that feels close to a dried out old tobacco Cuban cigar blended with coffee liqueur.

That last one is also relatively close to the classic combination of vanilla + vetiver. Luca Turin told me that the perfume called Habanita is precisely playing with a vanilla/vetiver combo, which at first sniff comes across as a completely new and unrecognizable (yet very pleasant) scent. He said that a wonderful metaphor for this phenomenon is like the song Loro by Gismonti, where in the second half the piano and the flute play in such a synchronized fashion that you get the impression that there’s a new instrument involved. I’ve been smelling vanilla/vetiver while listening to this song. It’s quite beautiful.


Humulene combined with d-limonene create an emergent “missing fundamental” type olfactory illusion of classical chewing gum flavor. It only works when Humulene is between 70% and 90% of the mixture (before adding ethyl alcohol). Cleanest example of “emergent scent” I’ve found.

Humulene is a simple scent of the category “earthy”, roughly similar to a vetiver essential oil but “one octave higher”. It also has a very mild musky undertone.

D-limonene is an orange/lemon-like scent. Extremely common in perfumery. Chances are something you ate today has it.

The simplest example I can think of to illustrate what an “emergent scent” is comes from the auditory illusion called “the missing fundamental”.

If you play 200 hertz together with 300 hertz and 400 hertz you will hallucinate an emergent 100 hertz tone.

The 100 Hz tone is not there! But it is quite real in your experience.

Of course if you are very acquainted with this auditory effect, you might notice the fundamental (100hz) is a bit fainter than expected, and infer it’s an illusion. But it is nonetheless very much present in your experience.

Likewise, when you smell Humulene + Vanillin at a 1:1 ratio you will get a third smell that emerges as a sort of gestalt that “bridges together” the two underlying notes.

You can probably infer the input scent is made up of two notes if you are really experienced with this kind of phenomenon. But the third note, the gestalt, does not disappear when you have “reduced” it to the two underlying notes. It’s still there. Thus, really, the whole is greater than the sum of its parts.


Hear the effect yourself: Missing fundamentals. Periodicity and Pitch

August 1st 2020

I like my coffee how I like my perfumes: with the fewest chemicals needed to cause the desired effect.

As an aside, learning about emergent effects in low-entropy perfume recipes makes me think that there could probably be a job for “scent simplification”. Namely, take something like cacao, with hundreds of molecules contributing to its characteristic scent. The question is: what is the minimum viable number of aromachemicals you can use to replicate it (within a Just Noticeable Difference unit)?

I suspect most natural scents that come from a complex entourage effect have relatively minimalistic reconstructions. A question that also emerges is: what is the most complex scent? I.e. what is the smell whose minimum reconstruction has the maximum number of molecular diversity?

[It’s important to distinguish between molecular entropy and phenomenal entropy. A solution of Agrumen Aldehyde Light and ethanol has low molecular entropy but pretty high phenomenal entropy, whereas a “lime accord” made of tens of molecules could be high in molecular entropy yet low in phenomenal entropy because it smells very cleanly like a ‘single note’]


A master perfumer like Ellena has memorized hundreds, if not thousands, of recipes for manufacturing smells. Many complex natural scents can be conjured with only a few ingredients. The scent of freesia, he explained, is created by combining two simple molecules: beta-ionone and linalool, both synthetics. (To give freesia a cold, metallic edge, a touch of allyl amyl glycolate is added.) The smell of orange blossom is made by combining linalool and methyl anthranilate, which smells like Concord grapes.


In my presence, Ellena once dipped a touche into a molecule called isobutyl phenal acetate, which has a purely chemical smell, and another touche into vanillin, a synthetic version of vanilla. He placed the two paper strips together, waved them, and chocolate appeared in the air. “My métier is to find shortcuts to express as strongly as possible a smell,” he explained. “For chocolate, nature uses eight hundred molecules. I use two.” He handed me four touches—vanillin plus the natural essences of cinnamon, orange, and lime. The combined smell was a precise simulation of Coca-Cola. “With me, one plus one equals three,” Ellena said. “When I add two things, you get much more than two things.”

August 5th 2020

Imagine you have been a musician for your village all your life. You play drums and acoustic guitar and you have never heard modern music. One day you are gifted an iPod and you listen for the first time to the crazy sounds of psychedelic trance. For the first time in your life you experience the wonders of reverb, flanging, distortions, and FM-synthesis. Surely this gives you a sense that your conception of music only tapped into a tiny fraction of what had always been possible.

An analogy could be made with smells: having tried essential oils one gets the impression of understanding what is possible in the realm of scents. But one day you discover Galaxolide, hedione, and eso E super. Like reverb and FM-synthesis in sound, these compounds are capable of giving surreal, unexpected, and space-warping properties to scents (much like reverb in sound, they are character impact molecules, meaning that they modify the presentation of other scents more than contributing a ‘flavor’ of their own).

Galaxolide in particular is something you have probably smelled, either in perfumes or detergents, but it really only becomes clear just how insane of a substance it is when you smell it raw. I associate it with “DMT Realm Aesthetics” – like a smell coming from another planet where hyperdimensional experiences are common everyday events, and the world of the arts uses exotic phenomenal time routinely. It has a vibe I can only describe as “having already always been here yet just arrived”. It’s probably what traveling in time feels like when you are in a transcendent Bardo between lifetimes.


Pellwall describes galaxolide thus: “Galaxolide is an isochroman musk, that has an odour profile that is liked by most people and is similar to a macrocyclic musk. It is strong, clean smelling and a good fixative. It combines well with other musks and is often used in combinations.”

In wikipedia, they describe the scent as: “a synthetic musk with a clean sweet musky floral woody odor”.

I think the musk-like quality accounts for maybe 60% of its effect. But I swear there is something much more special about it than just a clean musk. It has a kind of time-dilation effect, and it seems to my nose as a “musk but high-dimensional”. Perhaps it’s musk + the harmonics of musk. So while other musks are just a single note, galaxolide is like the feeling of a musky accordion.


I’ll write about my setup for doing this kind of research, but suffice to say that it’s super cheap if you know what you are doing. Each experiment (i.e. a little bottle with a few ml of a new combination in precise proportions) costs me about ~30 cents to make, all things considered (the cost of the materials, the ethanol, the pipettes, the bottle).

I highly recommend just getting a 2ml sample vial. It can cost as little as $2.16 (plus shipment) here: Galaxolide.

Other stellar molecules to try out to expand your conception of what’s possible:

Linalool, dihydro linalool, alpha-damascone, damascenone, helional, C-16 aldehyde (strawberry), agrumen aldehyde light, farnesene, nerolione, and alpha-ionone. All of that can cost you as little as $30. Not a bad price for expanding your “sense of what’s possible”.


I so wish I had a “DMT-smell accord” to use as a note in perfume compositions.

There is this one here meant to evoke the hallucinogenic state, but reportedly it has nothing to do with the actual scent of DMT, which I find very disappointing. I will try to find the way to emulate the scent of it – I suspect that linalyl acetate and coranol could be part of the compounds making up that accord. I’ll let you know if I manage to make anything vaguely resemblant of that scent.375x500.59536

Lemon Lavender World

One of the first essential oil combinations I fixated upon was that of lemon plus lavender. You could say it is the “speedball” equivalent of essential oil combos, for it relaxes and excites at the same time. I figured that trying to “understand” the “lemon-lavender world” would be a good exercise in the quest of mapping out the state-space of scents.


Lemon Lavender experiments

I currently have six different lemon essential oils from different brands and places, and seven lavender essential oils. To my surprise, the variability is very substantial. The lemon essential oils range from extremely sour and astringent to sweet and waxy. The lavenders I have also have many different qualities: some are very oily and flavorful, while others are particularly camphorous. Which of the qualities are “essential” for lemon and lavender is surely a matter of convention, though I also think they point to roughly objective attractors – the citrus sharpness of lemon rings high and has a cascading sourness that can be used for waking up the senses, whereas lavender has a narcotic entrancing reverb effect. My quest to understand, and ultimately create, lemon lavender smells was not defined in terms of merely reconstructing the standard natural smells, but as an attempt at understanding how these two qualities interact at the phenomenal level.

The diversity of lemon and lavender oils means that the space of possible combinations is even larger. Of the 42 possible combinations of one lavender oil and one lemon oil I have some are far more blissful and rich than others. I picked a few of my favorite ones to use as “model lemon-lavenders” to try to emulate.

Starting in the spirit that in order to deeply understand a scent I have to be able to construct it from scratch- so that I understand how each piece contributes to the whole- I set myself the goal of creating both lemon and lavender accords and then exploring their combinations. All starting from raw aromachemical ingredients, of course:

Making a Lemon Accord

I have always wanted to know what makes citrus fruits smell the way they do. Empirically, both isomers of limonene are a key piece of the puzzle. For instance, both lemon and mandarin oil have upwards of 80% limonene. Alas, if you smell limonene alone, you will notice it is somewhat one-dimensional in character. It IS pointing in the direction of “citrus” quite clearly, but on its own is indisputably too simple to evoke a real lemon scent.

I had a false start: aldehydes. Aldehyde C-8 through C-15 are all “extremely high-pitch scents”. They give a sharp edge to perfumes like Chanel No. 5 and the like. But they are very hard to use – partly because they are extremely potent. So for a couple of days I worked with combinations of citral and aldehydes that had, though a somewhat citric quality, mostly headache-inducing effects. I ended this series of experiments when I got a headache that lasted 24 hours (this goes to show how far I am willing to go to understand that sweet, sweet lemon qualia).

Taking a step back, I decided to explore a different angle. Valencene (note the great name) is very similar to limonene, except slightly lower in pitch. When mixed in equal proportions with limonene one gets a richer, more believable citrus scent – both molecules seem to say the same thing but in a slightly different voice, which results in a kind of chorus effect (unlike merely doubling the volume of a single voice). Alas, at this point the scent is still a bit flat, and not particularly lemon-like relative to near-enemy citrus fruits like the good old orange, mandarin, or grapefruit.

I recall being very puzzled by the scent of lime, as it seems like a kind of “super lemon” when it comes to its high-pitched sour and astringent character. And no matter how much I tried mixing citrus-like aromachemicals, I found it hard to get any hint of lime in the results. That is until I discovered that lime oil has a great deal of alpha- and beta-pinene. These are molecules that are primarily found in trees (in pines!) and smell very woody. As it turns out, to turn a citrus smell into an outright lime scent you need to add woody molecules. In retrospect, this was always hidden in the name: Lemon + Pine = Lime. After having this insight, I realized that even lemon requires a bit of alpha- and beta-pinene to distinguish it from orange scent.

After a lot of trial and error, the most convincing minimalistic lemon scent I identified is (numbers represent parts):

3 D-Limonene
3 Valencene
1 Citral
2 Linalool
1 Alpha-Pinene
1 Beta-Pinene
1 Nerolione (optional; for a rindy effect)

Making a Lavender Accord

This turned out to be more difficult than making a lemon accord. I think this is not only me: I also own two “fragrance oils” (those products that are advertised in the same context as essential oils, yet in the fine print reveal they are not at all natural, and instead are synthetic reconstructions) of lavender, and neither of the two smell anything like lavender. So I wouldn’t be the first to fail.



Linalool is a key ingredient of lavender, making up about 30% to 50% of most lavender essential oils. This is a very powerful aromachemical that seems to work as a gasoline-like fuel amplifier and modifier for any other scent (“there is no boring ten-carbon alcohol” – Luca Turin). It is also one of the things that makes lavender so narcotic and entrancing. On its own it is already quite interesting. But it is only one of the voices in lavender.

Then you have linalyl acetate, which makes up between 0% and 30% of lavender oil, depending on the species, place of origin, and time of harvest. Linalyl acetate has a “dry” quality, which I associate with “salt” (in fact if you just add this to the lemon accord above you get a smell I would describe as “salted margarita cocktail”). Alpha and beta pinene also play a role in lavender.

Interestingly, a lot of lavender oils also have up to 10% of camphor, which contributes to its narcotic get-well-soon cozy quality. Alas, it is hard to work with this material, and it always smells too synthetic to me. I found that instead I could double-down on beta-pinene, which is more camphorous than alpha-pinene (which is more earthy), and does the job quite nicely.

Finally, centifoleather, farnesene, and various alcohols like coranol can give “flavor” to the accord. In the end, I’ve settled on a minimalistic (but I think effective) arrangement. It does not quite hit the flavor of lavender, but I think does a good job at evoking its “character impact”:

4 Linalool
1 Alpha-Pinene
4 Beta-Pinene
2 Linalyl Acetate
3 Farnesene

Putting It All Together

Ultimately, adding these two accords (and their variations) together does not always produce the best results, as some aromachemicals are repeated and the proportions that give rise to the desired interactions can be scrambled by the combination. This, by the way, is a general reason why synthetic combinations span a much larger space of possible scents. In brief, because to make reconstructions with natural oils you are constrained by non-negative least squares methods, and many combinations may simply be inaccessible that way.

Anyhow – with the combination, I found that adding some character impact molecules like abroxan and helional was important to create a “bridge” between the two phenomenal characters. Alpha-ionol also seems to do something good here that is hard to put your finger on. But I think it’s that it adds the right kind of waxy rindy effect (which it has some of) in a way that does not make the mixture feel “dry” (which more classically citrus waxy smells like nerolione inevitably do). So the end result has some of these three molecules.

I am happy to say that the best lemon lavender reconstruction so far is about as good as the median natural lemon lavender mixture. It is not as good as the best lemon lavender oil mixture, though, but it is a start. I still expect to perfect it quite a bit before unleashing it into the world.

Ladies and gentleman, I present to you Lemon Lavender World:

1 Citral
3 D-Limonene
3 Valencene
4 Linalool
1 Alpha-Pinene
4 Beta-Pinene
2 Linalyl Acetate
2 Helional
3 Farnesene
1 Ambroxan
2 Alpha-Ionol
80 Ethanol

That Time Daniel Dennett Took 200 Micrograms of LSD (In Another Timeline)

[Epistemic status: fiction]

Andrew Zuckerman messaged me:

Daniel Dennett admits that he has never used psychedelics! What percentage of functionalists are psychedelic-naïve? What percentage of qualia formalists are psychedelic-naïve? In this 2019 quote, he talks about his drug experience and also alludes to meme hazards (though he may not use that term!):

Yes, you put it well. It’s risky to subject your brain and body to unusual substances and stimuli, but any new challenge may prove very enlightening–and possibly therapeutic. There is only a difference in degree between being bumped from depression by a gorgeous summer day and being cured of depression by ingesting a drug of one sort or another. I expect we’ll learn a great deal in the near future about the modulating power of psychedelics. I also expect that we’ll have some scientific martyrs along the way–people who bravely but rashly do things to themselves that disable their minds in very unfortunate ways. I know of a few such cases, and these have made me quite cautious about self-experimentation, since I’m quite content with the mind I have–though I wish I were a better mathematician. Aside from alcohol, caffeine, nicotine and cannabis (which has little effect on me, so I don’t bother with it), I have avoided the mind-changing options. No LSD, no psilocybin or mescaline, though I’ve often been offered them, and none of the “hard” drugs.


As a philosopher, I have always accepted the possibility that the Athenians were right: Socrates was quite capable of corrupting the minds of those with whom he had dialogue. I don’t think he did any clear lasting harm, but it is certainly possible for a philosopher to seriously confuse an interlocutor or reader—to the point of mental illness or suicide, or other destructive behavior. Ideas can be just as dangerous as drugs.


Dennett Explained by Brendan Fleig-Goldstein and Daniel A. Friedman (2019)

It would be quite fascinating to know what Dan would say about lived psychedelic states. With that in mind, here is an essay prompt originally conceived for GPT-3 to satisfy our curiosity:

And after seeing some surprising empirical results with his heterophenomenological methods when examining the experience of people on psychedelics, Daniel Dennett decided to experience it for himself by taking 200 micrograms of LSD. The first thing he said to himself as he felt the first indications of the come-up was…


Maggie and Anders

Maggie Wassinge and Anders Amelin (QRI Sweden volunteer coordinators and content contributors – see letters I & II, letters III, IV, V, & VI, and letters VII, VIII, & IX) decided to give it a go first. We shall then compare it with what GPT-3 can come up with at a later point.

In a way, what you are about to read can be thought of as Anders & Maggie’s simulation of a hyper-intelligent GPT-3-like system’s simulation of a hypothetical Daniel Dennett on LSD. So many layers, I know. But the results speak for themselves:

Dan says: Correlation is all that is needed. So what states a mind uses for modeling conditions of importance to it, is fundamentally arbitrary. Like with language. Words represent things to humans but there are many languages, and words do not resemble what they represent. They only correlate with what they represent, and the correlation needs to be learned. To do science about the mind, one does not need to attach any special weight to any conscious state of mind over any other. One person’s hope may be another person’s despair. These “qualia” are like internally projected hypo-languages which are different all over the map, if there were one. In fact there cannot be an interpersonal map of what things feel like personally. Only naïve people could hope for a fundamental linguistics of consciousness, as if these states were to constitute a universal language of some ground truth of the mind. Silly. Romantic. It’s all arbitrary. For the record, I never said subjective experiential states do not exist. People misrepresent me on that. What I am saying is that it will never be possible to scientifically map what the state that a word such as, for instance, “green”, translates to feels like by the brain of a given individual. My green could be your red.cielab-lch-color-tolerancing-methods

Just drop the whole idea of trying to map the state-space of qualia. That is my position. Or at least I know it is, logically. Right now I begin to notice how everything intensifies and becomes somehow more salient. More revealingly “real”. As I reflect on the notion of how “states” correlate, a humorous episode from my undergraduate student life so long ago, is brought to the surface. At Wesleyan it was, where I was taking a course in Art Appreciation. The lecturer was showing a slide of a still life. A bowl of fruit it was, conspicuously over-ripe. Pointing at one of the fruits, saying “Can anyone tell me what state this peach is in?” There was silence for about three seconds, then one student exclaimed: “Georgia”. Everyone laughed joyfully. Except me. I never quite liked puns. Too plebeian. Sense of humor is arbitrary. I believe that episode helped convince me that the mind is not mysterious after all. It is just a form of evolved spaghetti code finding arbitrary solutions to common problems. Much like adaptations of biochemistry in various species of life. The basic building blocks remain fixed as an operative system if you will, but what is constructed with it is arbitrary and only shaped by fitness proxies. Which are, again, nothing but correlations. I realized then that I’d be able to explain consciousness within a materialist paradigm without any mention of spirituality or new realms of physics. All talk of such is nonsense.Daniel_dennett_Oct2008

I have to say, however, that a remarkable transformation inside my mind is taking place as a result of this drug. I notice the way I now find puns quite funny. Fascinating. I also reflect on the fact that I find it fascinating that I find puns funny. It’s as if… I hesitate to think it even to myself, but there seems to be some extraordinarily strong illusion that “funny” and “fascinating” are in fact those very qualia states which… which cannot possibly be arbitrary. Although the reality of it has got to be that when I feel funniness or fascination, those are brain activity patterns unique to myself, not possible for me to relate to any other creature in the universe experiencing them the same way, or at least not to any non-human species. Not a single one would feel the same, I’m sure. Consider a raven, for example. It’s a bird that behaves socially intricately, makes plans for the next day, can grasp how tools are used, and excels at many other mental tasks even sometimes surpassing a chimpanzee. Yet a raven has a last common ancestor with humans more than three hundred million years ago. The separate genetic happenstances of evolution since then, coupled with the miniaturization pressure due to weight limitations on a flying creature, means that if I were to dissect and anatomically compare the brain of a raven and a human, I’d be at a total loss. Does the bird even have a cerebral cortex?03-brai-diagram

An out of character thing is happening to me. I begin to feel as if it were in fact likely that a raven does sense conscious states of “funny” and “fascinating”. I still have functioning logic that tells me it must be impossible. Certainly, it’s an intelligent creature. A raven is conscious, probably. Maybe the drug makes me exaggerate even that, but it ought to have a high likelihood of being the case. But the states of experience in a raven’s mind must be totally alien if it were possible to compare them side by side with those of a human, which of course it is not. The bird might as well come from another planet.Head_of_Raven

The psychedelic drug is having an emotional effect on me. It does not twist my logic, though. This makes for internal conflict. Oppositional suggestions spontaneously present themselves. Could there be at least some qualia properties which are universal? Or is every aspect arbitrary? If the states of the subjective are not epiphenomenal, there would be evolutionary selection pressures shaping them. Logically there should be differences in computational efficiency when the information encoded in qualia feeds back into actions carried out by the body that the mind controls. Or is it epiphenomenal after all? Well, there’s the hard problem. No use pondering that. It’s a drug effect. It’ll wear off. Funny thing though, I feel very, very happy. I’m wondering about valence. It now appeals strongly to take the cognitive leap that at least the positive/negative “axis” of experience may in fact be universal. A modifier of all conscious states, a kind of transform function. Even alien states could then have a “good or bad” quality to them. Not directly related to the cognitive power of intelligences, but used as an efficient guidance for agency by them all, from the humblest mite to the wisest philosopher. Nah. Romanticizing. Anthropomorphizing.

36766208_10160731731785637_6606215010454601728_oFurther into this “trip” now. Enjoying the ride. It’s not going to change my psyche permanently, so why not relax and let go? What if conscious mind states really do have different computational efficiency for various purposes? That would mean there is “ground truth” to be found about consciousness. But how does nature enable the process for “hitting” the efficient states? If that has been convergently perfected by evolution, conscious experience may be more universal than I used to take for granted. Without there being anything supernatural about it. Suppose the possibility space of all conscious states is very large, so that within it there is an ideally suited state for any mental task. No divine providence or intelligent design, just a law of large numbers.

The problem then is only a search algorithmic one, really. Suppose “fright” is a state ideally suited for avoiding danger. At least now, under the influence, fright strikes me as rather better for the purpose than attraction. Come to think of it, Toxoplasma Gondii has the ability to replace fright with attraction in mice with respect to cats. It works the same way in other mammals, too. Are things then not so arbitrarily organized in brains? Well, those are such basic states we’d share them with rodents presumably. Still can’t tell if fright feels like fear in a raven or octopus. But can it feel like attraction? Hmmm, these are just mind wanderings I go through while I wait for this drug to wear off. What’s the harm in it?

Suppose there is a most computationally efficient conscious state for a given mental task. I’d call that state the ground state of conscious intelligence with respect to that task. I’m thinking of it like mental physical chemistry. In that framework, a psychedelic drug would bring a mind to excited states. Those are states the mind has not practiced using for tasks it has learned to do before. The excited states can then be perceived as useless, for they perform worse at tasks one has previously become competent at while sober. Psychedelic states are excited with respect to previous mental tasks, but they would potentially be ground states for new tasks! It’s probably not initially evident exactly what those tasks are, but the great potential to in fact become more mentally able would be apparent to those who use psychedelics. Right now this stands out to me as absolutely crisp, clear and evident. And the sheer realness of the realization is earth-shaking. Too bad my career could not be improved by any new mental abilities.Touched_by_His_Noodly_Appendage_HD

Oh Spaghetti Monster, I’m really high now. I feel like the sober me is just so dull. Illusion, of course, but a wonderful one I’ll have to admit. My mind is taking off from the heavy drudgery of Earth and reaching into the heavens on the wings of Odin’s ravens, eternally open to new insights about life, the universe and everything. Seeking forever the question to the answer. I myself am the answer. Forty-two. I was born in nineteen forty two. The darkest year in human history. The year when Adolf Hitler looked unstoppable at destroying all human value in the entire world. Then I came into existence, and things started to improve.

It just struck me that a bird is a good example of embodied intelligence. Sensory input to the brain can produce lasting changes in the neural connectivity and so on, resulting in a saved mental map of that which precipitated the sensory input. Now, a bird has the advantage of flight. It can view things from the ground and from successively higher altitudes and remember the appearance of things on all these different scales. Plus it can move sideways large distances and find systematic changes over scales of horizontal navigation. Entire continents can be included in a bird’s area of potential interest. Continents and seasons. I’m curious if engineers will someday be able to copy the ability of birds into a flying robot. Maximizing computational efficiency. Human-level artificial intelligence I’m quite doubtful of, but maybe bird brains are within reach, though quite a challenge, too.

This GPT-3 system by OpenAI is pretty good for throwing up somewhat plausible suggestions for what someone might say in certain situations. Impressive for a purely lexical information processing system. It can be trained on pretty much any language. I wonder if it could become useful for formalizing those qualia ground states? The system itself is not an intelligence in the agency sense but it is a good predictor of states. Suppose it can model the way the mind of the bird cycles through all those mental maps the bird brain has in memory. Where the zooming in and out on different scales brings out different visual patterns. If aspects of patterns from one zoom level is combined with aspect from another zoom level, the result can be a smart conclusion about where and when to set off in what direction and with what aim. Then there can be combinations also with horizontally displaced maps and time-displaced maps. Essentially, to a computer scientist we are talking massively parallel processing through cycles of information compression and expansion with successive approximation combinations of pattern pieces from the various levels in rapid repetition until something leads to an action which becomes rewarded via a utility function maximization.


Axioms of Integrated Information Theory (IIT)

Thank goodness I’m keeping all this drugged handwaving to myself and not sharing it in the form of any trip report. I have a reputation for being down to Earth, and I wouldn’t want to spoil it. Flying with ravens, dear me. Privately it is quite fun right now, though. That cycling of mental maps, could it be compatible with the Integrated Information Theory? I don’t think Tononi’s people have gone into how an intelligent system would search qualia state-space and how it would find the task-specific ground states via successive approximations. Rapidly iterated cycling would bring in a dynamic aspect they haven’t gotten to, perhaps. I realize I haven’t read the latest from them. Was always a bit skeptical of the unwieldy mathematics they use. Back of the envelope here… if you replace the clunky “integration” with resonance, maybe there’s a continuum of amplitudes of consciousness intensity? Possibly with a threshold corresponding to IIT’s nonconscious feed-forward causation chains. The only thing straight from physics which would allow this, as far as I can tell from the basic mathematics of it, would be wave interference dynamics. If so, what property might valence correspond to? Indeed, be mappable to? For conscious minds, experiential valence is the closest one gets to updating on a utility function. Waves can interfere constructively and destructively. That gives us frequency-variable amplitude combinations, likely isomorphic with the experienced phenomenology and intensity of conscious states. Such as the enormous “realness” and “fantastic truth” I am now immersed in. Not sure if it’s even “I”. There is ego dissolution. It’s more like a free-floating cosmic revelation. Spectacular must be the mental task for which this state is the ground state!

Wave pattern variability is clearly not a bottleneck. Plotting graphs of frequencies and amplitudes for even simple interference patterns shows there’s a near-infinite space of distinct potential patterns to pick from. The operative system, that is evolution and development of nervous systems, must have been slow going to optimize by evolution via genetic selection early on in the history of life, but then it could go faster and faster. Let me see, humans acquired a huge redundancy of neocortex of the same type as animals use for avigation in spacetime locations. Hmmm…, that which the birds are so good at. Wonder if the same functionality in ravens also got increased in volume beyond what is needed for navigation? Opening up the possibility of using the brain to also “navigate” in social relational space or tool function space. Literally, these are “spaces” in the brain’s mental models.2000px-Migrationroutes.svg

Natural selection of genetics cannot have found the ground states for all the multiple tasks a human with our general intelligence is able to take on. Extra brain tissue is one thing it could produce, but the way that tissue gets efficiently used must be trained during life. Since the computational efficiency of the human brain is assessed to be near the theoretical maximum for the raw processing power it has available, inefficient information-encoding states really aren’t very likely to make up any major portion of our mental activity. Now, that’s a really strong constraint on mechanisms of consciousness there. If you don’t believe it was all magically designed by God, you’d have to find a plausible parsimonious mechanism for how the optimization takes place.

If valence is in the system as a basic property, then what can it be if it’s not amplitude? For things to work optimally, valence should in fact be orthogonal to amplitude. Let me see… What has a natural tendency to persist in evolving systems of wave interference? Playing around with some programs on my computer now… well, appears it’s consonance which continues and dissonance which dissipates. And noise which neutralizes. Hey, that’s even simple to remember: consonance continues, dissonance dissipates, noise neutralizes. Goodness, I feel like a hippie. Beads and Roman sandals won’t be seen. In Muskogee, Oklahoma, USA. Soon I’ll become convinced love’s got some cosmic ground state function, and that the multiverse is mind-like. Maybe it’s all in the vibes, actually. Spaghetti Monster, how silly that sounds. And at the same time, how true!


Artist: Matthew Smith

I’m now considering the brain to produce self-organizing ground state qualia selection via activity wave interference with dissonance gradient descent and consonance gradient ascent with ongoing information compression-expansion cycling and normalization via buildup of system fatigue. Wonder if it’s just me tripping, or if someone else might seriously be thinking along these lines. If so, what could make a catchy name for their model?

Maybe “Resonant State Selection Theory”? I only wish this could be true, for then it would be possible to unify empty individualism with open individualism in a framework of full empathic transparency. The major ground states for human intelligence could presumably be mapped pretty well with an impressive statistical analyzer like GPT-3. Mapping the universal ground truth of conscious intelligence, what a vision!

But, alas, the acid is beginning to wear off. Back to the good old opaque arbitrariness I’ve built my career on. No turning back now. I think it’s time for a cup of tea, and maybe a cracker to go with that.


Posthuman Art: Towards Full-Spectrum Positive Valence Amplification

Everyone says love hurts, but that is not true. Loneliness hurts. Rejection hurts. Losing someone hurts. Envy hurts. Everyone gets these things confused with love, but in reality love is the only thing in this world that covers up all pain and makes someone feel wonderful again. Love is the only thing in this world that does not hurt.

Excerpt from the wonderful conversation between Lucas Perry, Sam Barker, and David Pearce posted on June 24 (2020) at the Future of Life Institute Podcast (where Mike Johnson and I have previously participated). [Emphasis mine].

Lucas Perry: For this first section, I’m basically interested in probing the releases that you already have done, Sam, and exploring them and your inspiration for the track titles and the soundscapes that you’ve produced. Some of the background and context for this is that much of this seems to be inspired by and related to David’s work, in particular the Hedonistic Imperative. I’m at first curious to know, Sam, how did you encounter David’s work, and what does it mean for you?

Sam Barker: David’s work was sort of arriving in the middle of a series of realizations, and kind of coming from a starting point of being quite disillusioned with music, and a little bit disenchanted with the vagueness, and the terminology, and the imprecision of the whole thing. I think part of me has always wanted to be some kind of scientist, but I’ve ended up at perhaps not the opposite end, but quite far away from it.

Lucas Perry: Could explain what you mean by vagueness and imprecision?

Sam Barker: I suppose the classical idea of what making music is about has a lot to do with the sort of western idea of individualism and about self-expression. I don’t know. There’s this romantic idea of artists having these frenzied creative bursts that give birth to the wonderful things, that it’s some kind of struggle. I just was feeling super disillusioned with all of that. Around that time, 2014 or 15, I was also reading a lot about social media, reading about behavioral science, trying to figure what was going on in this arena and how people are being pushed in different directions by this algorithmic system of information distribution. That kind of got me into this sort of behavioral science side of things, like the addictive part of the variable-ratio reward schedule with likes. It’s a free dopamine dispenser kind of thing. This was kind of getting me into reading about behavioral science and cognitive science. It was giving me a lot of clarity, but not much more sort of inspiration. It was basically like music.

Dance music especially is a sort of complex behavioral science. You do this and people do that. It’s all deeply ingrained. I sort of imagine the DJ as a sort Skinner box operator pulling puppet strings and making people behave in different ways. Music producers are kind of designing clever programs using punishment and reward, or suspense and release, and controlling people’s behavior. The whole thing felt super pushy and not a very inspiring conclusion. Looking at the problem from a cognitive science point of view is just the framework that helped me to understand what the problem was in the first place, so this kind of problem of being manipulative. Behavioral science is kind of saying what we can make people do. Cognitive psychology is sort of figuring out why people do that. That was my entry point into cognitive psychology, and that was kind of the basis for Debiasing.

There’s always been sort of a parallel for me between what I make and my state of mind. When I’m in a more positive state, I tend to make things I’m happier with, and so on. Getting to the bottom of what tricks were, I suppose, with dance music. I kind of understood implicitly, but I just wanted to figure out why things worked. I sort of came to the conclusion it was to do with a collection of biases we have, like the confirmation bias, and the illusion of truth effect, and the mere exposure effect. These things are like the guardians of four/four supremacy. Dance music can be pretty repetitive, and we describe it sometimes in really aggressive terminology. It’s a psychological kind of interaction.

Cognitive psychology was leading me to Kaplan’s law of the instrument. The law of the instrument says that if you give a small boy a hammer, he’ll find that everything he encounters requires pounding. I thought that was a good metaphor. The idea is that we get so used to using tools in a certain way that we lose sight of what it is we’re trying to do. We act in the way that the tool instructs us to do. I thought, what if you take away the hammer? That became a metaphor for me, in a sense, that David clarified in terms of pain reduction. We sort of put these painful elements into music in a way to give this kind of hedonic contrast, but we don’t really consider that that might not be necessary. What happens when we abolish these sort of negative elements? Are the results somehow released from this process? That was sort of the point, up until discovering the Hedonistic Imperative.

I think what I was needing at the time was a sort of framework, so I had the idea that music was decision making. To improve the results, you have to ask better questions, make better decisions. You can make some progress looking at the mechanics of that from a psychology point of view. What I was sort of lacking was a purpose to frame my decisions around. I sort of had the idea that music was a sort of a valence carrier, if you like, and that it could be tooled towards a sort of a greater purpose than just making people dance, which was for Debiasing the goal, really. It was to make people dance, but don’t use the sort of deeply ingrained cues that people used to, and see if that works.

What was interesting was how broadly it was accepted, this first EP. There were all kinds of DJs playing it in techno, ambient, electro, all sorts of different styles. It reached a lot of people. It was as if taking out the most functional element made it more functional and more broadly appealing. That was the entry point to utilitarianism. There was sort of an accidentally utilitarian act, in a way, to sort of try and maximize the pleasure and minimize the pain. I suppose after landing in utilitarianism and searching for some kind of a framework for a sense of purpose in my work, the Hedonistic Imperative was probably the most radical, optimistic take on the system. Firstly, it put me in a sort of mindset where it granted permission to explore sort of utopian ideals, because I think the idea of pleasure is a little bit frowned upon in the art world. I think the art world turns its nose up at such direct cause and effect. The idea that producers could be paradise engineers of sorts, or the precursors to paradise engineers, that we almost certainly would have a role in a kind of sensory utopia of the future.

There was this kind of permission granted. You can be optimistic. You can enter into your work with good intentions. It’s okay to see music as a tool to increase overall wellbeing, in a way. That was kind of the guiding idea for my work in the studio. I’m trying, these days, to put more things into the system to make decisions in a more conscious way, at least where it’s appropriate to. This sort of notion of reducing pain and increasing pleasure was the sort of question I would ask at any stage of decision making. Did this thing that I did serve those ends? If not, take a step back and try a different approach.

There’s something else to be said about the way you sort of explore this utopian world without really being bogged down. You handle the objections in such a confident way. I called it a zero gravity world of ideas. I wanted to bring that zero gravity feeling to my work, and to see that technology can solve any problem in this sphere. Anything’s possible. All the obstacles are just imagined, because we fabricate these worlds ourselves. These are things that were really instructive for me, as an artist.

Lucas Perry: That’s quite an interesting journey. From the lens of understanding cognitive psychology and human biases, was it that you were seeing those biases in dance music itself? If so, what were those biases in particular?

Sam Barker: On both sides, on the way it’s produced and in the way it’s received. There’s sort of an unspoken acceptance. You’re playing a set and you take a kick drum out. That signals to people to perhaps be alert. The lighting engineer, they’ll maybe raise the lights a little bit, and everybody knows that the music is going into sort of a breakdown, which is going to end in some sort of climax. Then, at that point, the kick drum comes back in. We all know this pattern. It’s really difficult to understand why that works without referring to things like cognitive psychology or behavioral science.

Lucas Perry: What does the act of debiasing the reception and production of music look like and do to the music and its reception?

Sam Barker: The first part that I could control was what I put into it. The experiment was whether a debiased piece of dance music could perform the same functionality, or whether it really relies on these deeply ingrained cues. Without wanting to sort of pat myself on the back, it kind of succeeded in its purpose. It was sort of proof that this was a worthy concept.

Lucas Perry: You used the phrase, earlier, four/four. For people who are not into dance music, that just means a kick on each beat, which is ubiquitous in much of house and techno music. You’ve removed that, for example, in your album Debiasing. What are other things that you changed from your end, in the production of Debiasing, to debias the music from normal dance music structure?

Sam Barker: It was informing the structure of what I was doing so much that I wasn’t so much on a grid where you have predictable things happening. It’s a very highly formulaic and structured thing, and that all keys into the expectation and this confirmation bias that people, I think, get some kind of kick from when the predictable happens. They say, yep. There you go. I knew that was going to happen. That’s a little dopamine rush, but I think it’s sort of a cheap trick. I guess I was trying to get the tricks out of it, in a way, so figuring out what they were, and trying to reduce or eliminate them was the process for Debiasing.

Lucas Perry: That’s quite interesting and meaningful, I think. Let’s just take trap music. I know exactly how trap music is going to go. It has this buildup and drop structure. It’s basically universal across all dance music. Progressive house in the 2010s was also exactly like this. What else? Dubstep, of course, same exact structure. Everything is totally predictable. I feel like I know exactly what’s going to happen, having listened to electronic music for over a decade.

Sam Barker: It works, I think. It’s a tried and tested formula, and it does the job, but when you’re trying to imagine states beyond just getting a little kick from knowing what was going to happen, that’s the place that I was trying to get to, really.

Lucas Perry: After the release of Debiasing in 2018, which was a successful attempt at serving this goal and mission, you then discovered the Hedonistic Imperative by David Pearce, and kind of leaned into consequentialism, it seems. Then, in 2019, you had two releases. You had BARKER 001 and you had Utility. Now, Utility is the album which most explicitly adopts David Pearce’s work, specifically in the Hedonistic Imperative. You mentioned electronic dance producers and artists in general can be sort of the first wave of, or can perhaps assist in paradise engineering, insofar as that will be possible in the near to short terms future, given advancements in technology. Is that sort of the explicit motivation and framing around those two releases of BARKER 001 and Utility?

Sam Barker: BARKER 001 was a few tracks that were taken out of the running for the album, because they didn’t sort of fit the concept. Really, I knew the last track was kind of alluding to the album. Otherwise, it was perhaps not sort of thematically linked. Hopefully, if people are interested in looking more into what’s behind the music, you can lead people into topics with the concept. With Utility, I didn’t want to just keep exploring cognitive biases and unpicking dance music structurally. It’s sort of a paradox, because I guess the Hedonistic Imperative argues that pleasure can exist without purpose, but I really was striving for some kind of purpose with the pleasure that I was getting from music. That sort of emerged from reading the Hedonistic Imperative, really, that you can apply music to this problem of raising the general level of happiness up a notch. I did sort of worry that by trying to please, it wouldn’t work, that it would be something that’s too sickly sweet. I mean, I’m pretty turned off by pop music, and there was this sort of risk that it would end up somewhere like that. That’s it, really. Just looking for a higher purpose with my work in music.

Lucas Perry: David, do you have any reactions?

David Pearce: Well, when I encountered Utility, yes, I was thrilled. As you know, essentially I’m a writer writing in quite heavy sub-academic prose. Sam’s work, I felt, helps give people a glimpse of our glorious future, paradise engineering. As you know, the reviews were extremely favorable. I’m not an expert critic or anything like that. I was just essentially happy and thrilled at the thought. It deserves to be mainstream. It’s really difficult, I think, to actually evoke the glorious future we are talking about. I mean, I can write prose, but in some sense music can evoke paradise better, at least for many people, than prose.

And it continues on. I highly recommend listening to the whole podcast: it is wonderfully edited and musical pieces referenced in the interview are brought up in real time for you to listen to. Barker also made a playlist of songs specifically for this podcast, which are played during the second half of the recording. It is delightful to listen to music that you know was produced with the explicit purpose of increasing your wellbeing. A wholesome message at last! Amazing art inspired by the ideology of Paradise Engineering, arriving near you… very soon.

As an aside, I think that shared visions of paradise are really essential for solving coordination problems. So…

Please join me in putting on Barker’s track Paradise Engineering, closing your eyes, and imagining- in detail- what the creation of an Institute for Paradise Engineering on a grand scale would look like. What would a positive Manhattan Project of Consciousness entail? What is the shortest path for us to create such a large-scale initiative?

By the way: the song is only 4 minutes long. So its duration is perfect for you to use as a guiding and grounding piece of media for a positive DMT trip. Press “play” immediately after you vaporize the DMT, sit back, relax, and try to render in your mind a posthuman paradise in which Full-Spectrum Supersentient Superintelligence has won and the threat of Pure Replicators has been averted. If you do this, please let me know what you experience as a result.

Ps. It’s worth noting that Barker’s conception of art is highly aligned with QRI’s view of what art could be like. See, in particular, models 4 through 8 in our article titled Harmonic Society.

These are the answers to the most Frequently Asked Questions about the Qualia Research Institute. (See also: the glossary).

(Organizational) Questions About the Qualia Research Institute

  • What type of organization is QRI?

    • QRI is a nonprofit research group studying consciousness based in San Francisco, California. We are a registered 501(c)(3) organization.

  • What is the relationship between QRI, Qualia Computing, and Opentheory?

    • Qualia Computing and Opentheory are the personal blogs of QRI co-founders Andrés Gómez Emilsson and Michael Johnson, respectively. While QRI was in its early stages, all original QRI research was initially published on these two platforms. However, from August 2020 onward, this is shifting to a unified pipeline centered on QRI’s website.

  • Is QRI affiliated with an academic institution or university?

    • Although QRI does collaborate regularly with university researchers and laboratories, we are an independent research organization. Put simply, QRI is independent because we didn’t believe we could build the organization we wanted and needed to build within the very real constraints of academia. These constraints include institutional pressure to work on conventional projects, to optimize for publication metrics, and to clear various byzantine bureaucratic hurdles. It also includes professional and social pressure to maintain continuity with old research paradigms, to do research within an academic silo, and to pretend to be personally ignorant of altered states of consciousness. It’s not that good research cannot happen under these conditions, but we believe good consciousness research happens despite the conditions in academia, not because of them, and the best use of resources is to build something better outside of them.

  • How does QRI align with the values of EA?

    • Effective Altruism (EA) is a movement that uses evidence and reason to figure out how to do the most good. QRI believes this aesthetic is necessary and important for creating a good future. We also believe that if we want to do the most good, foundational research on the nature of the good is of critical importance. Two frames we offer are Qualia Formalism and Sentientism. Qualia Formalism is the claim that experience has a precise mathematical description, that a formal account of experience should be the goal of consciousness research. Sentientism is the claim that value and disvalue are entirely expressed in the nature and quality of conscious experiences. We believe EA is enriched by both Qualia Formalism and Sentientism.

  • What would QRI do with $10 billion?

    • Currently, QRI is a geographically distributed organization with access to commercial-grade neuroimaging equipment. The first thing we’d do with $10 billion is set up a physical headquarters for QRI and buy professional-grade neuroimaging devices (fMRI, MEG, PET, etc.) and neurostimulation equipment. We’d also hire teams of full-time physicists, mathematicians, electrical engineers, computer scientists, neuroscientists, chemists, philosophers, and artists. We’ve accomplished a great deal on a shoestring budget, but it would be hard to overestimate how significant being able to build deep technical teams and related infrastructure around core research threads would be for us (and, we believe, for the growing field of consciousness research). Scaling is always a process and we estimate our ‘room for funding’ over the next year is roughly ~$10 million. However, if we had sufficiently deep long-term commitments, we believe we could successfully scale both our organization and research paradigm into a first-principles approach for decisively diagnosing and curing most forms of mental illness. We would continue to run studies and experiments, collect interesting data about exotic and altered states of consciousness, pioneer new technologies that help eliminate involuntary suffering, and develop novel ways to enable conscious beings to safely explore the state-space of consciousness.

Questions About Our Research Approach

  • What differentiates QRI from other research groups studying consciousness?

    • The first major difference is that QRI breaks down “solving consciousness” into discrete subtasks; we’re clear about what we’re trying to do, which ontologies are relevant for this task, and what a proper solution will look like. This may sound like a small thing, but an enormous amount of energy is wasted in philosophy by not being clear about these things. This lets us “actually get to work.”

    • Second, our focus on valence is rare in the field of consciousness studies. A core bottleneck in understanding consciousness is determining what its ‘natural kinds’ are: terms which carve reality at the joints. We believe emotional valence (the pleasantness/unpleasantness of an experience) is one such natural kind, and this gives us a huge amount of information about phenomenology. It also offers a clean bridge for interfacing with (and improving upon) the best neuroscience.

    • Third, QRI takes exotic states of consciousness extremely seriously whereas most research groups do not. An analogy we make here is that ignoring exotic states of consciousness is similar to people before the scientific enlightenment thinking that they can understand the nature of energy, matter, and the physical world just by studying it at room temperature while completely ignoring extreme states such as what’s happening in the sun, black holes, plasma, or superfluid helium. QRI considers exotic states of consciousness as extremely important datapoints for reverse-engineering the underlying formalism for consciousness.

    • Lastly, we have a focus on precise, empirically testable predictions, which is rare in philosophy of mind. Any good theory of consciousness should also contribute to advancements in neuroscience. Likewise, any good theory of neuroscience should contribute to novel, bold, falsifiable predictions, and blueprints for useful things, such as new forms of therapy. Having such a full-stack approach to consciousness which does each of those two things is thus an important marker that “something interesting is going on here” and is simply very useful for testing and improving theory.

  • What methodologies are you using? How do you actually do research? 

    • QRI has three core areas of research: philosophy, neuroscience, and neurotechnology 

      • Philosophy: Our philosophy research is grounded in the eight problems of consciousness. This divide-and-conquer approach lets us explore each subproblem independently, while being confident that when all piecemeal solutions are added back together, they will constitute a full solution to consciousness.

      • Neuroscience: We’ve done original synthesis work on combining several cutting-edge theories of neuroscience (the free energy principle, the entropic brain, and connectome-specific harmonic waves) into a unified theory of Bayesian emotional updating; we’ve also built the world’s first first-principles method for quantifying emotional valence from fMRI. More generally, we focus on collecting high valence neuroimaging datasets and developing algorithms to analyze, quantify, and visualize them. We also do extensive psychophysics research, focusing on both the fine-grained cognitive-emotional effects of altered states, and how different types of sounds, pictures, body vibrations, and forms of stimulation correspond with low and high valence states of consciousness.

      • Neurotechnology: We engage in both experimentation-driven exploration, tracking the phenomenological effects of various interventions, as well as theory-driven development. In particular, we’re prototyping a line of neurofeedback tools to help treat mental health disorders.

  • What does QRI hope to do over the next 5 years? Next 20 years?

    • Over the next five years, we intend to further our neurotechnology to the point that we can treat PTSD (post-traumatic stress disorder), especially treatment-resistant PTSD. We intend to empirically verify or falsify the symmetry theory of valence. If it is falsified, we will search for a new theory that ties together all of the empirical evidence we have discovered. We aim to create an Effective Altruist cause area regarding the reduction of intense suffering as well as the study of very high valence states of consciousness.

    • Over the next 20 years, we intend to become a world-class research center where we can put the discipline of “paradise engineering” (as described by philosopher David Pearce) on firm academic grounds.

Questions About Our Mission

  • How can understanding the science of consciousness make the world a better place?

    • Understanding consciousness would improve the world in a tremendous number of ways. One obvious outcome would be the ability to better predict what types of beings are conscious—from locked-in patients to animals to pre-linguistic humans—and what their experiences might be like.

    • We also think it’s useful to break down the benefits of understanding consciousness in three ways: reducing the amount of extreme suffering in the world, increasing the baseline well-being of conscious beings, and achieving new heights for what conscious states are possible to experience.

    • Without a good theory of valence, many neurological disorders will remain completely intractable. Disorders such as fibromyalgia, complex regional pain syndrome (CRPS), migraines, and cluster headaches are all currently medical puzzles and yet have incredibly negative effects on people’s livelihoods. We think that a mathematical theory of valence will explain why these things feel so bad and what the shortest path for getting rid of them looks like. Besides valence-related disorders, nearly all mental health disorders, from clinical depression and PTSD to schizophrenia and anxiety disorders, will become better understood as we discover the structure of conscious experience.

    • We also believe that many (though not all) of the zero-sum games people play are the products of inner states of dissatisfaction and suffering. Broadly speaking, people who have a surplus of cognitive and emotional energy tend to play more positive sum games, are more interested in cooperation, and are very motivated to do so. We think that studying states such as those induced by MDMA that combine both high valence and a prosocial behavior mindset can radically alter the game theoretical landscape of the world for the better.

  • What is the end goal of QRI? What does QRI’s perfect world look like?

    • In QRI’s perfect f
