Algorithmic Reduction of Psychedelic States

Only when sexual choice favored the reportability of our subjective experiences- with the emergence of the mental clearing-house we call consciousness- did our strangely promiscuous introspection abilities emerge, such that we seem to have instant conscious access to such a range of impressions, ideas, and feelings. This may explain why philosophical writing about consciousness so often sounds like love poetry- philosophers of mind, like lovesick teenagers, dwell upon the redness of the rose, the emotional urgency of music, the soft warmth of skin, and the existential loneliness of the self. The philosophers wonder why such subjective experiences exist, given that they seem irrelevant to our survival prospects, while the lovesick teenagers know perfectly well that their romantic success depends, in part, on making a credible show of aesthetic sensitivity to their own conscious pleasures.

The Mating Mind: How Sexual Choice Shaped the Evolution of Human Nature (pg. 365) by Geoffrey F. Miller

A Darwinian Set and Setting

According to The Mating Mind, human sexual selection favors particular fitness-indicating traits, both physical and mental. In the context of mental traits, we have verbal and introspective abilities, agreeableness, conscientiousness, openness to experience, low neuroticism and extroversion. No matter how verbally capable and introspective a given person is, unless that is balanced with some degree of agreeableness, conscientiousness, etc. the person will not be all that attractive. But, when all else is being held equal, stronger verbal and introspective abilities are favored. Teenagers, arguably, know this best of all: courtship is intensely verbal.

Our minds evolved in a Darwinian environment. If people like Miller are right in thinking that language evolved as a fitness indicator, we are right to expect that the way we think and verbalize is biased to be impressive to the members of the opposite sex during courtship. Powerful introspective abilities, as it were, can make one’s language seem deeper, more romantic, and even at an entirely different level than that of one’s peers. In this backdrop of sexual choices and judgements, it is not surprising that humans would develop ever-increasing verbal and introspective capacities. At some point everyday life could not present sufficient opportunities for people, especially males, to show off their own abilities. And as these abilities increased over time, culture was forced to invent handicaps so that people could display their top capabilities. Over time, elaborate and competitive handicaps were integrated into the culture. Even verbal and introspective abilities at the top of the scale can still be compared side by side by using carefully selected handicaps: for example, poetry is exactly that; rhyme, rhythm and meter make it easier for the best poets to show off their excellent abilities. The handicaps adjust to the maximum level of competence in the population.

The space of handicaps that are used to show off traits that are reliable indicators of fitness is very large. From Greek Symposiums to modern day Frat Parties, Western civilization has embraced a niche subculture that uses chemical handicaps as a means to display verbal, social and creative skills. If you can philosophize after drinking a gallon of wine, or stay capable of managing the playlist after 16 cheap cans of beer, you are showing off your biological robustness. Clearly, many of our ancestors were capable of impressing potential sexual mates with a mixture of booze, loud music and stunning philosophical conversations.

One could argue that psychedelics have come to disrupt our traditional games of handicaps. “Sure you can drink a bottle of tequila and sing in a band, but can you take three hits of acid and tell me what your experience reveals about the intrinsic nature of consciousness?” Psychedelics are, in a way, a cultural hyper-stimulus that presents the most difficult and interesting handicap currently in existence for verbal and introspective abilities.

Cultures can have an allergic reaction to the states of consciousness that these agents can disclose; people are afraid that psychedelic users will discover something that they themselves don’t know. Notably, psychedelicists have been both demonized and deified since the 60s. Sure, these researchers became extremely open minded, and in many ways weird. But, above all, they became extremely interesting people. And interesting people who challenge the current games of status can cause cultural allergic reactions.

Every acid head and psychedelic researcher has a pet theory of what these compounds are really doing in one’s mind. Many of these folk theories about the effects of psychedelics involve ontologies that currently have little scientific support (such as souls, thought fields, spirit worlds, archetypes, alien conspiracies, and so on). Although we cannot rule out explanations of this sort out of hand, the ontologies themselves are so abstract and poorly defined that we cannot accept them as useful forms of reductions. That said, their future versions will be more interesting. It is likely that committed, rational, spiritual psychedelic users will formalize models of this sort at some point. Rather than talking about a “spirit world,” they will talk about “mind-independent extra-dimensional space that consciousness can access in altered states” and then go on to define the differential equations that govern consciousness’s interactions with this space. When this happens, we will be in a much better position to assess the validity of these models, test the reality of those spaces, and perhaps even recruit the extra-dimensional inhabitants of these worlds for computational tasks.

Psychedelic experiences drastically increase people’s introspection, capacity for deep aesthetic appreciation, while at the same time increasing their ability to entertain unusual ideas. Insofar as the selection pressures of our introspective abilities have been heavily biased towards courtship ability, it is not surprising that people tend to immediately cast self-enhancing, life-affirming and magical narratives into their interpretations of their personal psychedelic experiences. After all, having a very interesting story to tell is highly praised during courtship. Are people’s psychedelic narratives a modern day form of the peacock’s tail? While psychedelic talk does not yet form part of any mainstream game of courtship, I envision this changing in the next decades. Undoubtedly, the most insightful, sound, and scientifically rigorous members of the Super-Shulgin Academy will attract attention, status, resources and… desirable mates.

What is the deep structure of psychedelic experiences?

Psychedelics seem to have a generalized effect on one’s consciousness. At minimum, we could talk of experience amplification. Without delving into specifics, psychedelics introduce spontaneous activity into our consciousness that our mind is compelled to integrate somehow. Our state of consciousness changes dynamically as our mind adjusts itself to the incoming stimulation. The result is tightly dependent on the interplay between our brain anatomy, motivational system and the actual changes to the micro-structure of consciousness induced by LSD.

As John Lilly noted in light of his psychedelic experiences: “in the province of the mind, what one believes to be true is true or becomes true, within certain limits to be found experientially and experimentally. These limits are further beliefs to be transcended. In the mind, there are no limits…”.* While there are reasons not to take this literally, we have grounds for claiming that a large number of limits on our experience are placed there by our deeply held beliefs and attitudes. The space of possible LSD experiences that a single individual can experience is much larger than what said individual will typically be able to explore in practice. Many limits are imposed by his or her beliefs and background assumptions, rather than by physiology per se. Social cognition is a profound attractor in psychedelic experiences. “What will I say about this? What would this person think about this experience? etc.” are captivating thoughts. However, they occupy valuable mental space. And the thick mental judgements that people naturally focus on come with large conceptual and emotional baggage that taints the experience. Meditators, philosophers and scientists are more likely to set aside some time during their explorations to delve more deeply into what the energy introduced by LSD can produce in one’s consciousness.

After extreme training and tens (or hundreds) of trips, dedicated psychonauts will discover qualities that all of the trips share. Most people will likely experience a variant of Lilly’s realization that whatever you believe can be perceived as true during psychedelic experiences. Lilly emphasized the limitless quality of the mind, but one must wonder: If one can experience as true anything conceivable, are we not, then, limited by what we can conceive? No matter how much time one spends with an open mind waiting for new and interesting ideas to take shape, one cannot know the nature of what one has not yet even conceived of.

It may be true that we will always find fundamental limits that cannot be overcome. There are fundamental physiological constraints to the possible configurations of our consciousness, and arguably, chemical agents, while capable of expanding the space of possibilities, will not automatically give access to all possible states of consciousness. As future research is likely to show, 2C-B and LSD probably facilitate slightly different kinds of thoughts and experiences. Thus the limits of our mind are at least to a large extent the result of our physiology. Memes and meditation can only go so far.

In addition to physiological limits, the structure of the state-space of qualia is itself a constraint on what can and cannot be experienced. To the extent that psychedelic states enable the exploration of a larger space of possible experiences, we are more likely while on psychedelics to find states of consciousness that demonstrate fundamental limits imposed by the structure of the state-space of qualia. In normal everyday experience we can see that yellow and blue cannot be mixed (phenomenologically), while yellow and red can (and thus deliver orange). This being a constraint of the state-space of qualia itself is not at all evident, but it is a good candidate and many introspective individuals agree. On psychedelic states one can detect many other rules like that, except that they operate on much higher-dimensional and synesthetic spaces (E.g. “Some feelings of roughness and tinges of triangle orange can mix well, while some spiky mongrels and blue halos simply won’t touch no matter how much I try.” – 150 micrograms of LSD).

One of the objectives of Qualia Computing is to define the state space of possible experiences and the interdependencies between them. While normal everyday states of consciousness are important datapoints, I predict that the bulk of the most useful information will come from studying the behavior and mechanics of consciousness in radically altered states. To this end, however, we should focus on simple explanations that can be generalized to all psychedelic experiences.

Starting Background Assumptions

For the purpose of this article I will assume that direct realism, in all of its guises, is wrong. That is, I will assume that any mind-independent object can only be experienced indirectly. What we experience is not the object (or beings) themselves, but a qualia-furnished representation entirely contained within one’s mind (this is often called the simulationist account of perception). Furthermore, I will also assume that the behavior of  the universe can be fully described with the Standard Model of physics (or a future version of it).

In what is to follow I will propose, as a first approximation, an algorithmic reduction of psychedelic states; I will propose a set of changes in our consciousness that (1) is as simple and assumption-free as possible, and (2) can be used to reconstruct as many psychedelic effects as possible.

Two Kinds of Reduction

The word reduction in the context of philosophy of science has a lot of historical and conceptual baggage. In the context of this article, I will use the word in the following sense: We say that a property of a given phenomenon X reduces to Y if we can fully explain X’s property by referencing Y’s properties. X can be a physical phenomenon, a mathematical construct or even an experience. Y is an ontology with interaction rules, which allow the pieces of said ontology to interact with one another. We do not commit to the idea that Y itself needs to be the fundamental (or true) ontology of X. But we do want to make sure that Y is at least more fundamental than X in some appropriate sense. So what kind of ontologies can Y have? In the context of philosophy of mind, reductions usually attempt to account for not only the behavior of consciousness but also for its underlying nature. Thus, functionalism is both a reduction program as well as a philosophical take on what the mind fundamentally is.

Thankfully, we do not need to commit to any ontology in order to advance a particular style of reduction. Reductions are useful regardless: they reduce the amount of information needed to describe a phenomenon, and if accurate, they can also make useful predictions. Finally, these reductions can provide hints for how to bridge different areas of science; by identifying isomorphisms or even further reductions, entire fields can cross-pollinate once their respective reductions are compatible (such as biology and chemistry or chemistry and physics).

Atomistic Reduction

For most intents and purposes, science relies on a particular kind of reduction that we can call atomistic reduction. This style of reduction focuses on explaining macroscopic phenomena by modeling it as the emergent structure of many particles interacting with one another at a much finer level of resolution. Even though this style of reduction is usually fruitful (e.g. thermodynamics), it can be counter-productive to assume in some situations. An extreme case would be the quantum computer. If states of superposition help a computer find an answer, it will be hard to explain the behavior of said superposition by postulating that it actually reduces to little particles interacting using simple rules. The model could in principle be worked out, but at the cost of very high complexity. It would be much easier to start with a quantum-mechanical ontology that allows the superposition of wavefunctions! Then what is left is to reduce the rest of the computer to quantum mechanics (which is possible, given that particle models and quantum mechanical models usually converge at the macroscopic limit).

It is tempting to try to reduce the properties of the mind (including psychedelic states) using an atomistic reduction. Unfortunately, the phenomenal binding problem adds a complication to this reduction. Rather than discussing (right now) whether an atomistic (and thus classical) account will ultimately be capable of modeling conscious experience, we will side-step this problem by using a different style of reduction. We will focus only on the algorithmic level of analysis.

Algorithmic Reduction

Without assuming a fundamental ontology (atoms, fields, wavefunctions, etc.) we can still make a lot of progress. We can restrict ourselves to identifying what we call an algorithmic reduction: find a set of procedures, state-spaces, shapes and overall main effects out of which you can reconstruct as much of the observed behavior as possible.

In reality, every reduction is, at least in part, an algorithmic reduction. By specifying a particular ontology such as “particles”, we restrict the shape of our possible reductions. By keeping the reduction at the algorithmic level, we allow arbitrary ontologies to be the final explanations (then depending on actual empirical measurements). The main criteria for success still includes (1) the overall complexity of the model, and (2) the explanatory power of the model. In other words, how easily and precisely does the model reconstruct the behavior of our experiences?

A Zoo of Psychedelic Effects

PsychonautWiki has a detailed and fascinating taxonomy of reported psychedelic visual effects. One could argue that all of these countless effects are completely unique. As a philosopher might put it, these effects may ultimately be qualitatively irreducible to one another. But what are the chances that a simple molecule would happen to trigger a whole zoo of unrelated effects? As a form of reduction, nothing is achieved by stating that every effect is its own unique phenomenon.

Four Principal Operators: A Simple Algorithmic Model of Psychedelic States

In trying to account for the strange effects of psychedelics, we will aim to propose as few main effects as possible and then use these effects, and their interactions, to derive all of the remaining effects. By doing this, we will be algorithmically reducing the complex phenomena found in psychedelic states. In turn, this will allow us to increase our understanding of the source of information processing benefits provided by psychedelic states, and to derive new and exciting applications of such states. Additionally, by identifying a good algorithmic reduction, we might be able to refine the states themselves, to amplify their benefits while minimizing the drawbacks.

The model we will treat for now has four main effects, and with those four effects we will attempt to reconstruct the rest. These effects are:

  1. control interruption
  2. drifting
  3. eidetic hallucinations/enhanced pattern recognition/apophenia
  4. symmetry detection/symmetry propagation



Symmetric drifting. What would Giulio Tononi think about this? Source.

Control interruption is the simplest and most universal psychedelic effect. It enables the buildup of qualia in one’s consciousness. People say that psychedelics are intense, deep, bright, etc. Every experience, whether a thought, a smell or an emotion, seems to be both stronger and longer-lasting on psychedelics.

Things seem more lively, and this is not because a switch is suddenly turned on and your experience of the current input is amplified. Rather, one seems to be experiencing a gentle overlap of many previous frames (and feature bundles) of one’s experience. In medium to high doses, this can give rise to solid frame stacking. In turn, the buildup of sensation creates complex patterns of interference:

In order for a perceptual system to transition from a linear to a nonlinear state, negative feedback control must be subverted. If control is entirely removed then perception becomes totally unconstrained, leaving a system that is quickly overloaded with too much information. If control is placed in a state where it is partially removed or in a toggled superposition where it is alternately in control and not in control over the period of a rapid oscillation, then the constraints of linear sensory throughput will bifurcate into a nonlinear spectrum of multi-stable output with signal complexity correlating to the functional interruption of control. Common entheogenic wisdom states that you must relinquish control and submit to the experience to get the most out of psychedelics. Holding onto control causes negative experiences and amplifies anxiety; letting go of control and embracing unconstrained perception is a central psychedelic tenet. This demonstrates that psychedelics directly subvert feedback control over linear perception to promote states of unconstrained consciousness.

– Control Interrupt Model of Psychedelic Action, PIT

Control interruption explains a large variety of effects, including the increase in the raw intensity (and amount) of experience, as well as the longer lasting positive afterimages (and thus tracers). Here we show a simple example of this effect. Consider the “original stimuli” to be what one experiences under a sober state. Likewise, consider the 9 squares to be different states of consciousness brought up by various psychotropic combinations.



The 9 gifs you see above are simulations of control interruption using a simple feedback model (which we will describe in detail in a later article). The x-axis has different “echo strengths” while the y-axis has varying feedback strengths. These are two of the model parameters. Notice that the lower right corner is a credible rendition of something that people describe as moments of eternity. These are experiences where time seems to stop due to an over-saturation of regular and ordered qualia.

When considering the following effects, don’t forget that control interruption is also going on all the time. The stranger the psychedelic effect, the more intense it is.

Drifting is responsible for breathing walls, animated plants, feelings of boundary dissolution, merging and melting, and so on. Small amounts of drifting usually involve individual feature detachments from perceptual objects (such as the color and shape of a chair becoming dissociated). Medium amounts of drifting make textures flow constantly. If one’s experience was made of tiny magnetic gears that are usually aligned in a coherent way, drifting would result from increasing the overall energy of the system. Thus, the visual system is constantly descending to “more aligned local states” while incoming energy is constantly adding noise and destroying all of the alignment progress made.


Source: PsychonautWiki, Anonymous

A particularly salient aspect of drifting is that features and locally-bound fragments of experience can drift in any direction in 3D. Pieces of the wall don’t only drift left and right, but also forwards and backwards.

On high doses of psychedelics or synergistic combinations of dissociatives and psychedelics (e.g. LSD + nitrous, 2C-B + ketamine, etc.), drifting can become all-encompassing. A critical point is crossed when one loses the capacity to define a mainframe of experience (the dominating orientation-giving island of locally bound experience that we use as a reference point). When this happens, one feels like one cannot tell left from right, or up from down. One simply experiences a constant chaotic flow of experience. In some cases one can even spot interesting instabilities that resemble actual physical instabilities found in fluid mechanics (such as the Kelvin–Helmholtz instability).

Drifting does not occur in isolation, and its mechanics are dependent on the particular set and setting in which the psychedelic experience is developing. From a computational point of view, drifting can be useful because it allows a quick exploration of the state-space of possible local binding configurations between the phenomenal objects present in one’s experience. Indeed, not only does red fail to mix with green, but many of the synesthetic qualia varieties present in a scene with constant drifting will refuse to touch each other. Drifting feels like there is some sort of psychedelic energy (somewhat reminiscent of anxiety, but not restricted to body feelings) that overheats certain parts of one’s conscious experience, and in turn disassembles the local connections there.

Enhanced Pattern Recognition: This effect refers to the transient (but often powerful) lowering of the detection threshold for previously experienced patterns and known ontologies (e.g. animals, plants, people, etc.). Psychedelics, in other words, temporarily increase one’s degree of apophenia. Another name given to this effect is eidetic hallucinations. From a Bayesian point of view, the effect could be described thus: psychedelics intensify the effect of our priors. As explained in Getting Closer to Digital LSD, Google’s deep belief neural network inceptionist technique works by finding bundles of features that trigger high-level neurons (such as face-detectors, object-detectors, etc) at sub-threshold levels (e.g. “this almost looks like a frog”) and then modifying the picture so that the network more strongly detects those same high level features. This particular algorithm can be understood in terms of the pharmacological action of psychedelics: one can have breakthroughs of eidetic hallucinations by impairing the inhibitory control coming from the cortex.

In a sense we could say that while tracers are the result of “simple cell control interruption”, eidetic hallucinations are the result of “complex cell control interruption.” The former allows the build-up of colors, edges and simple shapes, while the latter amplifies the features that trigger high-level percepts such as faces and objects.


Enhanced Pattern Recognition / Eidetic Hallucinations / Visial Apophenia

The way one directs attention during a psychedelic trip influences the way eidetic hallucinations evolve over time. For this reason any psychedelic replication movie will probably require human input (in the form of eye-tracking) in order to incorporate human saliency preferences and interests into an evolving virtual psychedelic trip simulated with the Inceptionist Method.

Lower Symmetry Detection and Propagation Thresholds: Finally, this is perhaps the most interesting and scientifically salient effect of psychedelics. The first three effects are not particularly difficult to square with standard neuroscience. This fourth effect, while not incompatible with connectionist accounts, does suggest a series of research questions that may hint at an entirely new paradigm for understanding consciousness.

I have not seen anyone in the literature specifically identify this effect in all of its generality. The lowering of the symmetry detection threshold really has to be experienced to be believed. I claim that this effect manifests in all psychedelic experiences to a greater or lesser extent, and that many effects can in fact be explained by simply applying this effect iteratively.

Psychedelics make it easier to find similarities between any two given phenomenal objects. When applied to perception, this effect can be described as a lowering of the symmetry detection threshold. This effect is extremely general and symmetry should not be taken to exclusively refer to geometric symmetry.

How symmetries manifest depends on the set and setting. Researchers interested in verifying and exploring the quantitative and subjective properties of this effect will probably have to focus first on a narrow domain; the effect happens in all experiential modalities.

For now, let us focus on the case of visual experience. In this domain, the effect is what PsychonautWiki calls Symmetrical Texture Repetition:


Credit: Chelsea Morgan from PsychonautWiki and r/replications

Symmetry detection can be (and typically is) recursively applied to previously detected symmetry bundles. A given symmetry bundle is a set of n-dimensional symmetry planes (lines, hyperplanes, etc.) for which the qualities of the experience surrounding this bundle obey the symmetry constraints imposed by these planes. The planes can create mirror, rotational or oblique symmetry. Each symmetry bundle is capable of establishing a merging relationship with another symmetry bundle. These relationships are fleeting, but they influence the evolution of the relative position of each plane of symmetry. When x symmetry planes are in a merging relationship, one’s mind tries to re-arrange them (often using drifting) to create a symmetrical arrangement of these x symmetry planes. To do so, the mind detects one (or several) more symmetry planes, along which the previously-existing symmetry planes are made to conform, to organize in a symmetrical way (mirror, rotational, translational or otherwise). There is an irresistible subjective pull towards those higher levels of symmetry. The direction of highest symmetry and meta-symmetry feels blissful, interesting, mind-expanding, and awe-producing.

If one meditates in a sensorially-minimized room during a psychedelic experience while being aware that one’s symmetry detection threshold has been lowered by the substance, one can recursively re-apply this effect to produce all kinds of complex mathematical structures in one’s mind.

In the future, perhaps at a Super-Shulgin Academy, people will explore and compare the various states of consciousness that exhibit peak symmetry. These states would be the result of iteratively applying symmetry detection, amplification and re-arrangement. We would see fractals, tessellations, graphs and higher dimensional projections. Which one of these experiences contains the highest degree of inter-connectivity? And if psychedelic symmetry is somehow related to conscious bliss, which experience of symmetry is human peak bliss?

The pictures above all illustrate possible peak symmetry states one can achieve by combining psychedelics and meditation. The pictures illustrate only the core structure of symmetries that are present in these states of consciousness. What is being reflected is the very raw “feels” of each patch of your experiential field. Thus these pictures really miss the actual raw feelings of the whole experience. They do show, however, a rough outline of symmetrical relationships possible in one of these experiences.

Since control interruption is also co-occurrent with the psychedelic symmetry effect, previously-detected symmetries tend to linger for long periods of time. For this reason, the kinds of symmetries one can detect at a given point in time is a function of the symmetries that are currently being highlighted. And thanks to drifting and pattern recognition enhancement, there is some wiggle room for your mind to re-arrange the location of the symmetries experienced. The four effects together enable, at times, a smooth iterative integration of so many symmetries that one’s consciousness becomes symmetrically interconnected to an unbelievable degree.

What may innocently start as a simple two-sided mirror symmetry can end up producing complex arrangements of self-reflecting mirrors showing glimpses of higher and higher dimensional symmetries. Studying the mathematical properties of the allowed symmetries is a research project that has only just begun. I hope one day dedicated mathematicians describe in full the class of possible high-order symmetries that humans can experience in these states.

Anecdotally, each of the 17 possible wallpaper symmetry groups can be instantiated with this effect. In other words, psychedelic states lower the symmetry detection threshold for all of the mathematically available symmetrical tessellations.


All of the 17 2-dimensional wallpaper groups can be experienced with symmetry planes detected, amplified and re-arranged during a psychedelic experience.

Revising the symmetrical texture repetition of grass shown above, we can now discover that the picture displays the wallpaper symmetry found in the lower left circle above:


In very high doses, the symmetry completion is so strong that at any point one risks confusing left and right, and thus losing grasp of one’s orientation in space and time. Depersonalization is, at times, the result of the information that is lost when there is intense symmetry completion going on. One’s self-models become symmetrical too quickly, and one finds it hard to articulate a grounded point of view.

The Micro-Structure of Consciousness

At Qualia Computing we explore models of consciousness that acknowledge the micro-structure of consciousness. Experiences are not just higher-order mental operations applied to propositional content. Rather, an instant of experience contains numerous low-level textural properties. This is true for every sensory modality, and I would argue, even for the what-its-likeness of thought itself. Even just thinking about a mathematical idea (ex. “the intersection of two arbitrary sets”) is done by interacting with a background of raw feels, and these raw feels determine our attitudes and interactions with the ideas we are trying to abstract (some people, for example, experience emotional distress when trying out mathematical problems, and this is not because certain mathematical spaces are inherently unpleasant or anxiety-inducing).

In the case of vision, the micro-structure of consciousness is capable of supporting at least the following low-level features: color, color gradients, points, edges, oriented movement, and acceleration. A full conversation about the range of visual features that we are capable of experiencing is a discussion for another time. But for the time being, it will suffice to point out that (static) models of peripheral vision only need 5 summary statistics. With only five summary stats you can create textures that a human will find impossible to distinguish in peripheral vision.

These so-called mongrels are textural metamers (equivalence classes of subjectively indistinguishable input patterns). The state-space of perceivable visual textures is the space of possible mongrels, and that is an example of the sort of micro-structure we are looking for. Unlike the cozy high-definition space inscribed in the fovea, most of the information found in our sensory modalities comes in the form of textures that are mappable to state-spaces of summary statistics.


Psychedelic symmetry detection and amplification operates on the inner structure of mongrels. The fact that the mongrels are the objects becoming symmetric is something that can elude introspection until someone points it out. It happens right in front of any tripper’s eyes and yet people don’t seem to report it very often (if at all). This may be a result of the fact that the fine-grained structure of consciousness is rarely a topic of conversation, and that we usually describe what we see in the fovea (unless we have no other option). Our words usually refer to whole percepts or, at best, the simplest raw values of experience (such as the hue of colors or the presence of edges). And yet, the structure of our mongrels is quite obvious once symmetry propagation has conformed a large patch of your experience to have a tessellated identical mongrel repeating across it.


How Are these Components Related to Each Other?

The Kaleidoscopic technique to induce qualia annealing relies on a combination of drifting and symmetry detection in order to resolve implicit inconsistencies within one’s own memory gestalts. As we live and grow our experienced evidence base, we accumulate memories and impressions of many worldviews. Each worldview is, in a way, a response to all of the previous ones (or at least the memorable ones) and the current situation and the problems one is facing. Thanks to the four effects here described, a person can utilize a psychedelic state to increase the probability of the systematic co-occurrence of (usually) mutually-exclusive gestalts (worldviews) and thus enable their mutual awareness. And with mutual awareness, the symmetry detection and amplification effect creates (somehow forcefully) a unified phenomenal object that incorporates the inconsistent views into an unbiased (or less biased) point of view. One can achieve a higher order of memetic and affective integration.

Psychedelics as Introspectoscopes**

Given the symmetry detection and amplification property of psychedelics, one can reasonably argue that psychedelic states may be able to reveal the properties of the micro-structure of consciousness. Timothy Leary, among others, described LSD as a sort of microscope for one’s psyche. The very word psychedelic means mind-manifest (the manifestation of one’s mind). Given the four components of these experiences, the fact that psychedelics work as some sort of microscope should not be surprising. Symmetry detection and control interruption multiply the amount of raw experience, while pattern recognition shows you what you are expecting (your priors become evident) and drifting makes the fleeting synesthetic effects malleable and easier to move around. People generally agree that psychedelics can show you subtle aspects of your own mind with stark clarity. But can they reveal the intrinsic properties of the nature of qualia at the most fundamental level?

The way to achieve this may be to create a fractal structure of symmetries in such a way that any tiny part of one’s experience can get reflected throughout the entirety of the phenomenal structure. One can then use eidetic hallucinations (or further symmetry detection) to focus and stabilize the fractal structure. Thus one would multiply the surface area of all of one’s attention into countless replicas of the micro-structure of a given part of one’s experience. A fractal kaleidoscopic mirror amplifier chamber is exactly what I imagine when I think about how to analyze the fine-grained structure of consciousness. And it so happens that meditation plus psychedelics can allow you to (fleetingly) build just that.


Psychedelic Introspectoscope (fractal kaleidoscope of generalized symmetries) to amplify arbitrary qualia values (such as particular emotions, phenomenal colors, synesthetic inter-junctions, etc.)

Any subtle qualia space can be multiplied countless times in such a way that all of one’s experience becomes a coherent interlocking structure that can be perceived all at once. If one wants to study, for example, the possible interactions between two hues of color, one can amplify the boundary between two regions that make the desired contrast of hues and make the entire fractal structure amplify this boundary hundreds of times.

Arguably, if one discovers that certain qualia values cannot be mixed in the introspectoscope (such as blue and yellow), one may still not know if these are fundamental constraints, or if they are the result of our connectome structure. If, on the other hand, two qualia values can mix in the introspectoscope, then we would know that they are not fundamentally mutually exclusive. Thus we would find out relational properties of the very state-space of qualia.

Reducing All Effects

Can we derive all psychedelic effects using the four components discussed above? While this is not yet possible, I trust that further work will show how most of the weird (and weirder) effects of psychedelics may be reduced to relatively simple (but not always atomistic) algorithms applied to the micro-structure of consciousness. I anticipate that we will discover that high doses actually produce entirely new effects (for example, what happens on 400 micrograms of LSD often include qualitative jumps from what happens at 150 micrograms). To note, ontological qualia and other subtle aspects of consciousness may resist reduction for still many more decades to come.

*Programming and Meta programming in the Human Biocomputer

**An Introspectoscope is a hypothetical apparatus that enables a person to study the deep structure of his or her own consciousness. The concept comes from a paper in the making by Andrew Y. Lee. Obviously this comes with significant challenges. Some challenges come from the fact that we are trying to analyze something very small, and other challenges come from the fact we are trying to analyze qualia. Additionally, there are unique challenges that come from analyzing microscopic qualia qua microscopic qualia. I suggest that we use methods that amplify the micro-structure by taking advantage of fractal states: recursive and scale-free symmetry planes can amplify anything minute to a prominent place in the entire consciousness. Be careful not to amplify pain!

How to secretly communicate with people on LSD


About 18 months ago I had a really cool idea: What if we could communicate with people who are high on LSD in such a way that sober people can’t understand?* I call this idea psychedelic cryptography (PsyCrypto for short).

The GIFs above do just that: The left one is the “original” and it shows how you perceive it while sober. The GIF on the right shows what it’s like to see the GIF on the left after taking 100 micrograms of LSD. Notice anything different?

The first thing to note is that it is easier to see what letter is hidden here (C). On a closer inspection, you can also notice another amazing fact: It turns out that there are gaps between the vertical columns! This feature pops-up with clarity and is self-evident on the right GIF, and yet one needs to carefully observe the left GIF to notice that this is happening. That piece of information is not obvious when you are sober. Hence, while a sober person may infer what the hidden letter is, only a person on a psychedelic will see right away that there are gaps between the columns. Can you think of how to use this as a communication tool?

The approach shown above is only one of a plethora of ways of communicating with people on psychedelics. Here I will mention just a couple low-hanging fruits, give a few ideas for how to extend psychophysical research to build animations in a principled way, and discuss an awesome speculative application of this research.

Hopefully this article will spark interest and motivate both the psychedelic replication and the psychophysics community to come up with more innovative communication methods.

Do psychedelics enhance performance?

Drug “education” emphasizes the functional, perceptual, cognitive and affective impairments caused by the acute and chronic use of psychedelic substances. Psychedelics impair reaction time, linear thought, verbal expression, and a large range of everyday activities. This much is clear. It is undeniable that not all tasks are suitable for psychedelic experiences: Filing taxes, giving lectures to large audiences, and passing the polygraph test may all be rather poor choices for psychedelic activities.

But impairment is not the whole story. It is obvious to anyone who has researched the matter that psychedelics have some peculiar mind-enhancing properties. Any decent scientific account of psychedelic states has to provide information about the ways in which this particular state of consciousness confers genuine advantages.

And a great scientific account will explain why these particular trade-offs exist, and how we can best use them to (1) understand the mind, (2) achieve our human potential, and (3) address mental illness in a meaningful way.

Harman & Fadiman found a very large performance enhancement in the Witkins Embedded Figures test upon the administration of 100µg of LSD or 200mg of Mescaline. That is one of the most remarkable results of their study, which of course is not to diminish the relevance of their results concerning the rate of outstanding scientific discoveries. Unfortunately, the absence of drug-free controls in that study makes it less useful for convincing skeptics. When the study is replicated, it would be ideal to make it double-blind and not only include drug-free placebo controls, but also use an active performance-enhancing placebo, such as amphetamine.

Likewise, it is now clear that the self-insight concerning difficult emotional subjects can be radically amplified during therapeutic psychedelic sessions.  How and why this happens is still a rather difficult mystery.

Finally, we are currently experiencing a memetic explosion with regards to the use of micro-doses. Although we don’t yet have formal double-blind placebo-controlled research on the benefits of micro-dosing LSD, the wealth of anecdotal evidence is too large to ignore. For LSD, a micro-dose is defined as a dose in the 10-20 microgram range. The awesome Gwern is, to my knowledge, one of the few biohackers to have run a placebo-controlled experiment on himself. Although he found no positive effects, I suspect that is largely due to the sort of activities that he cares about. A more noticeable enhancement would be observed on artists, writers and possibly mathematicians. It is genuinely exciting that there is a new wave of attention to this particular application of psychedelics: General, all-purpose life-enhancement.

A Fantastic Speculative Application

If psychedelic states of consciousness provide some sort of information-processing advantage over sober states, this advantage may be possible to exploit for secret communication. Conversely, if there is any information-delivery method that only people on psychedelics can understand, it follows that psychedelic states have distinct information-processing advantages over sober states. From a purely PR point of view, obtaining a portfolio of methods to secretly transmit information to high-people will do a lot of beneficial work in showing the potential benefits of psychedelics. This is partly what motivates my research.

Even more awesome is the idea that this technology can lead to the creation of a video-game that only people on psychedelics can understand and play. For a sober person the game would look like an incomprehensible bundle of dots, edges, colors, sounds, etc. But a person sufficiently zonked would perceive crystal-clear images and easy-to-infer objectives. Only a sufficient amount of LSD would allow you to score a single point in this game.

Low Hanging Fruit

The simplest method is to take advantage of the longer-lasting after-images experienced under the influence. This happens to be one of the most robust effects that psychedelics have, and there seems to be a very clear dose-dependent curve in the intensity of these lingering phosphenes. Neurologically, this is explained by the Control Interrupt Model of Psychedelic Action, which can be summarized as follows: Our cortex’s main role is to provide inhibitory control on thalamic activity. The serotonergic activity of psychedelics blocks this control signal, and thus prevents the swift extinction of qualia once the triggering stimuli (whether internal or external) is removed.**

The basic idea for using tracers to communicate information is to provide, little-by-little, pieces of information that can be assembled into a coherent whole only if you use lingering after-images as building blocks.

Psychophysics for Psychedelic Research: Afterimages/Tracers

In order to find the right parameters to make awesome visualizations that can only be interpreted during psychedelic experiences, we will need to do a lot of trial-and-error, and ideally, build quality psychophysical tools. The following are some of the most important questions that we need to answer before we can go wild and build the psychedelic video-game:

  1. What is the dose-dependent decay function of tracers’ brightness?
  2. What is the additive function? Do similar colors average out? Do opposite colors cancel out?
  3. What is the range of features that remain in one’s experiential field? Is this dose-dependent?
  4. Do lingering features interact with one another? Do they achieve after-the-fact local phenomenal binding?
  5. What is the role of synesthesia in tracers?

To elaborate a little: The first question is about the rate of decay of phosphenes as a function of the dose and the time since the presentation of the stimuli. The GIF at the top of this page assumes an exponential gamma-corrected decay function.

The second question goes a little deeper, and it inquires about the way in which successive after-images of simple features (such as color and brightness) interact. If you first show a red square followed by a yellow one, do you then experience two overlapping but unblended colors? Or do you experience the average of the two (a hue of orange)? (If you know the answer from first-hand experience, please comment below!)

According to abundant anecdotal evidence (erowid, PsychonautWiki, r/psychonaut, etc.) the kind of perceptual objects that linger in one’s experiential field is dose-dependent. On small doses only colors and edges linger, while on higher doses you may experience emotions, faces, abstract concepts and even ontological qualia for many more seconds than normal. But what is the precise equation that describes this?

The fourth question is getting into more serious and difficult-to-research territory. Namely, we would want to know how different features interact with one another once they are lingering in one’s experiential field. If you first look at the blue sky and then look at a white cube, do you perceive a blue cube? More stunningly: If you think about the concept of recursion and then look at a tree, do you see recursion in the tree? (anecdotally, this definitely happens). The amazing thing about this particular question is that it may get at the very reason why consciousness was recruited by natural selection for information-processing purposes: There are some qualia that can be locally bound and some that can’t. This determines the range of constraints with which our mind implements constraint satisfaction solvers. But that’s a story for another post.

Finally, studying synesthesia during psychedelic experiences will almost certainly require the combination of neuro-imaging (such as fMRI) and quality psychophysics. I will explore this question further at a later time.

Answering the Questions

In order to answer most of the above questions, we can use the following paradigm: In order to test a theory you will want to (1) create interesting animations that produce particular effects, (2) create simulations of how these animations should look like under psychedelic vision, and (3) ask participants to rate the degree of similarity between the actual and predicted experiences.

For example, the GIFs below illustrate how an image might be seen if after-images are additive in nature. In other words, if you do experience orange when you flash red and yellow in quick succession, we can predict that the image on the left would be seen as the image on the right while on LSD. Is this so? I don’t know! Let me know if you happen to try it out.


Answering these questions using this and other paradigms will be very valuable to neuroscience.***

Textures (Once Again)

In Psychophysics for Psychedelic Research: Textures we discussed how we can use psychophysical tools and computational models in order to measure deficits and enhancements in our visual pattern recognition ability while under the influence of LSD. This is done by measuring the size of the Just Noticeable Differences (JND) for each of the summary statistics our visual system can recognize in peripheral vision. I have yet to collect real data from people under the influence, but thankfully the paradigm is already fleshed out. (Dear psychophysical researcher reading this blog, please feel free to use this approach!). Presumably both textures and after-images can be used to encode information that only high people can read.

A proof of concept for how to do this would be to encode information in binary code: Take a set of summary statistics that high people are good at distinguishing (and sober people confuse). Then show pairs of textures, one on the left and one on the right, so that the texture on the right has either the same or different summary statistics as the one on the left. If the textures are different then that encodes a 0. And if they are the same, that encodes a 1. Make sure that this particular summary statistic difference is only noticeable by people on psychedelics and you will have a state-dependent visual binary encryption!

Since you can communicate anything using a binary sequence, you can use this to provide any information you may want. But will your zonked friends be able to string together 1024 1s and 0s in order to decode a verbal message? Unlikely.

As the sole way of communicating information, textures are an unlikely candidate. But they may fit well as a component of a complex array of stimuli. If we can answer questions (3) and (4) we may be able to flash textures in sequence in such a way that their summary statistics are combined. While a pair of textures may not provide a lot of information, a sequence of them may overlap in such a way that high-level features begin to appear.

Hence, maybe we can build a sequence of textures that will make a person on LSD experience a particular face, or a dog. The sober person will remain clueless, though, since the consecutive textures fail to become integrated into a coherent percept.

Using Text

According to Shulgin there was a study conducted in the 60s that showed that people on psilocybin can read a text with fewer letters. What does this mean? Take a random text like a children’s story. Then remove X% of letters from it at random (substituting them by an underscore to show that a letter is missing).

Every person has a comprehension threshold: A 55-percenter would only be able to read texts that have 55% or more of their letters remaining. If that person takes psilocybin, then the comprehension threshold may drop to, say, 44%. This test should be particularly easy to replicate since it does not require any sort of image processing. Would you be interested in building an online test that determines your comprehension threshold? If you do, make sure to ask “are you on a psychedelic currently?” and collect the data!

Perhaps this generalizes to other areas of verbal comprehension. For instance, can you understand spoken words with more syllables taken out? What about sign language?

Inspired Work

These are just a few promising approaches. I am confident that by opening this idea up to the broader academic and psychedelic community a lot more ideas will blossom. If you were inspired by this article to build your own psychophysical toolkit, make sure to let me know in the comments below. And remember: I’m always looking for collaborators. 🙂

* LSD here is a shorthand for psychedelics in general.

** Control Interrupt Model of Psychedelic Action: In his awesome book called Psychedelic Information Theory, James Kent argues that the visual and cognitive components of psychedelic experiences can be explained as the effect of subtle disruptions to the inhibitory control cycle of perception. He calls this theory the Control Interrupt Model of Psychedelic Action. The basic idea is that in order for our experience of the world to be linear and stable there must be mechanisms in place that regulate the overall loop of consciousness. In other words, when we open our eyes, the image in out visual field does not become arbitrarily brighter over time. Nor is it the case that our visual field gets as bright as it can if you give it enough time. Rather, we have in place a negative feedback mechanism involving lateral inhibition and inhibitory projections from the cortex to the thalamus that regulates the brightness of our experience.

This inhibitory control mechanism occurs a discrete number of times per second. Therefore “control interruption” caused by psychedelics, in this model, is conceived as a periodical failure of inhibitory control that allows aspects of one’s experience to be sustained for longer than usual. The frequency of control interruption is specific to the psychedelic used. As the article conjures, salvia and nitrous oxide produce control interruption at a frequency of 8-11 and 12-15 Hz, respectively. On the other hand, DMT disrupts control at a much higher frequency (24-30+ Hz). This control interrupt creates “a standing hallucinogenic interference pattern in the consciousness of the subject”.

*** As argued by Julien Dubois  and Rufin VanRullen in “Visual Trails: Do the Doors of Perception Open Periodically?” tracers may be very significant when it comes to reverse-engineering the human visual system. How many frames per second do we experience? How long do the images last in the visual field? Does this effect generalize to high-level features, or is it specific to colors and edges? Thus, building psychedelic communication tools would be of great value to neuroscience.

A workable solution to the problem of other minds

Deciding whether other entities are also conscious is not an insoluble philosophical problem. It is tricky. A good analogy might be a wire puzzle. At a first glance, the piece you have to free looks completely locked. And yet a solution does exist, it just requires to represent a sufficiently large number of facts and features that our working memory is not enough.


Usually showing the solution once will not fully satisfy one’s curiosity. It takes some time to develop a personally satisfying account. And to do so, we need to unpack how the various components interact with one another. After a while the reason why the free piece is not locked becomes intuitive, and at the same time you may also encounter mathematical arguments and principles to complement your understanding.

At first, though, the free piece looks and feels locked.

I think the problem of other minds is perceived similarly to a wire puzzle. At first it looks and feels insoluble. After a while, though, many suspect that the problem can be solved. This essay proposes a protocol that may point in the right direction. It could have some flaws as it is currently formulated, so I’m open to refinements of any kind. But I believe that it represents a drastic improvement over previous protocols, and it gets close to being a fully functioning proof of concept.

Starting from the basics: An approach that is widely discussed is the application of a Turing test. But a Turing test has several serious flaws when used as a test of consciousness. First, many conscious entities can’t pass a Turing test. So we know that it could have a very poor recall (missing most conscious entities). This problem is also present in every protocol I’m aware of. The major problem with it is that when an entity passes a Turing test, this can be counted as probabilistic evidence in favor of a large number of hypothesis, and not only to the desired conclusion that “this entity is conscious.” In principle highly persuasive chatbots could hack your entity recognition module by presenting hyperstimuli created by analyzing your biases for styles of conversation.

Your brain sees faces everywhere (cartoons, 2D computer screens, even clouds). It also sees entities where there are none. It might be much more simple to *trick* your judgement than actually create a sentient intelligence. Could the entity given the Turing test be an elaborate chatobot with no phenomenal binding? It seems likely that could take place.

Thus passing a Turing test is also not a guarantee that an entity is conscious. The method would have low recall and probably low accuracy too.

The second approach would be to simply *connect* your brain to the other entity’s brain (that is, of course, if you are not talking about a disembodied entity). We already have something like the Corpus Callosum, which seems to be capable of providing a bridge that solves the phenomenal binding problem between the hemispheres of a single person. In principle we could create a biologically similar, microfunctionally equivalent neural bridge between two persons.

Assuming physicalism, it seems very likely that there is a way for this to be done. Here, rather than merely observing the other person’s conscious experience, the point of connecting would be to become one entity. Strong, extremely compelling personal identity problems aside (Who are you really? Can you expect to ‘survive’ after the union? If you are the merged entity, does that mean you were always the same consciousness as the one with whom you merged?, etc. More on this on later posts), this possibility opens up the opportunity to actually corroborate that another entity is indeed conscious.

Indeed separate hemispheres can have very different opinions about the nature of reality. Assuming physicalism, why would it be the case that you can’t actually revert (or instantiate for the first time) the union between brains?

The previous idea has been proposed before. I think it is a significant improvement over the use of a Turing test, since you are directly addressing the main phenomenon in question (rather than its ripples). That said, the method has problems, and epistemic holes.  In brief, a big unknown is the effect that interfacing with another conscious experience has on both conscious experiences. For example, some people have (like Eliezer Yudkowsky and Brian Tomasik) argued that your interaction with the other brain could functionally expand your own mind. As it were, the interaction with the other brain could be interpreted as expanding your own mind by obtaining a large hardware upgrade. Thus it could be that the whole experience of being connected and becoming one with another entity is a fantasy of your recently-expanded mind. It can give you the impression that the other brain was already conscious before you were connected to it. So you can’t rule out that it was a zombie before and after the connection was over.

But there is a way out. And this is the stimulating part of the essay. Because I’m about to untangle the wires.

The great idea behind this solution is: Phenomenal puzzles. This one phenomenal puzzle linked here is about figuring out the appropriate geometry of color (arranging the state-space in an Euclidean manifold so that the degrees of subjective differences between colors are proportional to their distances). Doing this requires the ability of comparing the various parts of an experience to each other and being able to remember the comparison. In turn this can be iterated and generate a map of subjective differences. This is an instance of what I call qualia computing, where you need to be in touch with the subjective quality of your experience and to be capable of comparing sensations.

In brief, you want to give the other entity a puzzle that can only be solved by a conscious entity via manipulating and comparing qualia. The medium used to deliver the puzzle will be a first-person merging of brains: To share the puzzle you first connect with the entity you want to test.

By doing this, by sharing the puzzle when you are connected to the other entity, you will be able to know its inner referents in terms of qualia. While connected, you can point to a yellow patch and say “this is yellow.” Possibly, both halfs will have their own system of private referents (a natural consequence of having slightly different sense organs which make variable mappings between physical stimuli and qualia). But as a whole the merged entity will be able to compare notes with itself about the mapping of stimuli to qualia in both halfs. The entity could look at the same object from the point of view of its two heads at the same time and form an unified visual field, which incorporates the feed from the two former “personal-sized” visual fields (similarly to how you incorporate sensory stimuli from two eyes. Now you’ll see with four). The color appearance of the object could have a slightly different quality when the two visual fields are compared. That’s the fascinating thing about phenomenal binding. The differences in mappings between stimuli and qualia of the two former entities can be compared, which means that this difference can be analyzed and reasoned about and added to both repertoires of hippocampal snapshots of the current experience.

Then, when you disconnect from the other and there are two streams of consciousness going on again, you will both know what that “yellow” referred to. This overcomes the age-old problem of communicating private referents, and mutually agreeing on name for private referents. This way, the pieces of the (phenomenal) puzzle will be the same in both minds.

For the test to work, the specific question needs to stay secret until it is revealed briefly before merging.

Imagine that you have a set of standardized phenomenal puzzles. Psychologists and people who have done the test before tend to agree that the puzzles in the set do require you to explore a minimum number of states of consciousness. The tests have precise conceptual answers. These answers are extremely difficult to deliver by accident or luck.

The puzzles may require you to use external tools like an image editor or a computer. This is because computers can enable you to program combinations of sensory input in precise ways. This expands the phenomenal gamut you can reach. In turn one can calibrate sensory input to have nice properties (ex. use gamma correction).  The puzzles will also be selected based on the time sentient beings typically take to solve them.

When you want to perform the test, you meet with the entity right after you finish reading the phenomenal puzzle. The puzzle is calibrated to not be solvable in the time it will take you to connect to the other entity.

When you connect your brain to the other entity and become one conscious narrative, the entire entity reads the puzzle to itself. In other words, you state out loud the phenomenal puzzle by clearly pointing to the referents of the puzzle within your own “shared” experience. Then you disconnect the two brains.

In the time that the other entity is trying to solve the puzzle you distract yourself. This way you can prevent yourself from solving the puzzle. Ideally you might want to bring your state of consciousness to a very low activity. The other entity will have all of its stimuli controlled to guarantee there is no incoming information. All the “qualia processing” is going on through approved channels. When the entity claims to have solved the puzzle, at that point you connect your brain back to it.

Does the merged entity know anything about the solution to the puzzle? You search for a memory thread that shows the process of solving the puzzle and the eventual answer. Thanks to the calibration of this puzzle (it has also been given to “merged” entities before) we know you would need more time to solve it. Now you may find yourself in a position where you realize that if the other entity was a zombie, you would have somehow solved a phenomenal puzzle without using experience at all. If so, where did that information come from?

With the memory thread you can remember how the other entity arrived at the conclusion. All of the hard work can be attributed to the other entity now. You witness this confirmation as the merged entity, and then you disconnect. You will still hold redundant memories of the period of merging (both brains do, like the hemispheres in split-brain patients). Do you know the answer to the puzzle? You can now check your memory for it and see that you can reconstruct the answer very quickly. The whole process may even take less time than it would take you to solve the puzzle.

If you know the answer to the puzzle you can infer that the other entity is capable of manipulating qualia in the same way that you can. You would now have information that your mind/brain could only obtain by exploring a large region of the state-space of consciousness… which takes time. The answer to the puzzle is a verifiable fact about the structure of your conscious experience. It gives you information about your own qualia gamut (think CIELAB). In summary, the other entity figured out a fact about your own conscious experience, and explained it to you using your own private referents.

You can then conclude that if the entity solved the phenomenal puzzle for you, it must be capable of manipulating its qualia in a semantically consistent way to how you do it. A positive result reveals that the entity utilizes conscious algorithms. Perhaps even stronger: It also shares the generalizable computational power of a sapient mind.

Unfortunately just as for the Turing test, not passing this test is not a guarantee that the other entity lacks consciousness. What the test guarantees is a high precision: Near every entity that passes the test is conscious. And that is a milestone, I think.

Do you agree that the problem of other minds is like a wire puzzle?

Now go ahead and brainstorm more phenomenal puzzles!

Manifolds of Consciousness: The emerging geometries of iterated local binding

The qualia manifolds

Ever noticed implicit geometries in the structure of the qualia you deal with on a daily basis?

So here is one observation about our experience. Visual experience has two major dimensions and one minor one (depth). This sensory modality is experienced as either 2 or 3 dimensional (and ambiguous points in between are also instantiated at times). Now, it also has a specific kind of topological features. It seems that the edges of the visual field are the edges of a patch in Euclidean space. The edges are not connected to each other. At first, it might take you by surprise to consider hypothetical visual fields with edges that are actually connected. Maybe you could make it a torus, by connecting edges left and right as well as those at the top and the bottom of the visual field. It’ll make a manifold of experience. You may also twist it before connecting it, making a Klein bottle or a projective plane.


Real Projective Plane. Imagine your visual field connected to itself in this way by twisting and joining the edges. 

A common reaction to this idea is “it may be impossible to do that, maybe the geometry of our visual field is the only possible one.” Without actually going ahead and interfering with your mind and brain directly it is unlikely I’ll be able to show conclusively it is possible. But there is a strong intuition pump available to help you conceive of the possibility.

So, touch your arm. Your writs more specifically. Using a finger make a circle around the wrist. You end up where you started, and yet you only advanced in one direction.

Phenomenal puzzles – CIELAB

Answer sheet to phenomenal puzzle #1:

Phenomenological studies reveal that we have three major qualia-poles that compose all experienced colors. Luminance is the first: How subjectively bright is it? The other two: We obtain red and green on two opposite sides, and blue and yellow on the normal of that pole.



The qualia that you are now experiencing on the left of your sensorium must match the schema to your right. Allow some room for normal human drawing errors. Is the chart similar enough to the subject’s solution to warrant a positive result?

Materials: Tester (t), neural bridge (nb), and entity (e).

Protocol: t and e must read the protocol. Let t read the promt of the phenomenal puzzle. Connect t’s brain to e’s brain with the nb at time t = 0. Adjust the connection setting to 1st person merging (fully unified sense of self). Phenomenal binding between brains is achieved. In that state, the equivalence between qualias in, say, vision, can be established. The united mind determines the relationship between visual qualias of both sub units (like a person would compare the feeling in both her hands). Then from the memory of t the entire being retells the puzzle using the available qualia, so that he visualizes what has to be solved in both of its subunits. Then both brains are disconnected.

During the phase that follows after the first disconnection e attempts to solve the phenomenal puzzle on its own. All of the sensory stimuli to e are carefully controlled to prevent any form of leakage of the solution. e is allowed to use visual aids such as computer programs that help him manipulate his experience with great freedom.

At the same time, one needs to carefully control the mental state of t. The particular sensory input t receives is less important than guaranteeing that t does not make the sort of cognitive moves that would lead to an answer to the puzzle. For instance, distractions are great ways of doing this.

If the puzzle has been ‘standardized’ to be solved within a given range of time (its ecological difficulty has been assessed widely) one waits that amount and then reconnect t’s and e’s brain.

In that second period of union, the united entity assesses e’s solution to the phenomenal puzzle. If it has been solved, then t will be able to conclude that e is conscious even when they are disconnected. For e to have that certainty the roles will have to be reversed.

The puzzle itself

What are the axis of phenomenal color? Draw a map of color that separates it into phenomenally continuous colors at the same distance in terms of subjective difference.
