24 Predictions for the Year 3000 by David Pearce

In response to the Quora question Looking 1000 years into the future and assuming the human race is doing well, what will society be like?, David Pearce wrote:


The history of futurology to date makes sobering reading. Prophecies tend to reveal more about the emotional and intellectual limitations of the author than the future. […]
But here goes…

Year 3000

1) Superhuman bliss.

Mastery of our reward circuitry promises a future of superhuman bliss – gradients of genetically engineered well-being orders of magnitude richer than today’s “peak experiences”.

2) Eternal youth.

More strictly, indefinitely extended youth and effectively unlimited lifespans. Transhumans, humans and their nonhuman animal companions don’t grow old and perish. Automated off-world backups allow restoration and “respawning” in case of catastrophic accidents. “Aging” exists only in the medical archives.

3) Full-spectrum superintelligences.

A flourishing ecology of sentient nonbiological quantum computers, hyperintelligent digital zombies and full-spectrum transhuman “cyborgs” has radiated across the Solar System. Neurochipping makes superintelligence all-pervasive. The universe seems inherently friendly: ubiquitous AI underpins the illusion that reality conspires to help us.

4) Immersive VR.

“Magic” rules. “Augmented reality” of earlier centuries has been largely superseded by hyperreal virtual worlds with laws, dimensions, avatars and narrative structures wildly different from ancestral consensus reality. Selection pressure in the basement makes complete escape into virtual paradises infeasible. For the most part, infrastructure maintenance in basement reality has been delegated to zombie AI.

5) Transhuman psychedelia / novel state spaces of consciousness.

Analogues of cognition, volition and emotion as conceived by humans have been selectively retained, though with a richer phenomenology than our thin logico-linguistic thought. Other fundamental categories of mind have been discovered via genetic tinkering and pharmacological experiment. Such novel faculties are intelligently harnessed in the transhuman CNS. However, the ordinary waking consciousness of Darwinian life has been replaced by state-spaces of mind physiologically inconceivable to Homo sapiens. Gene-editing tools have opened up modes of consciousness that make the weirdest human DMT trip akin to watching paint dry. These disparate states-spaces of consciousness do share one property: they are generically blissful. “Bad trips” as undergone by human psychonauts are physically impossible because in the year 3000 the molecular signature of experience below “hedonic zero” is missing.

6) Supersentience / ultra-high intensity experience.

The intensity of everyday experience surpasses today’s human imagination. Size doesn’t matter to digital data-processing, but bigger brains with reprogrammed, net-enabled neurons and richer synaptic connectivity can exceed the maximum sentience of small, simple, solipsistic mind-brains shackled by the constraints of the human birth-canal. The theoretical upper limits to phenomenally bound mega-minds, and the ultimate intensity of experience, remain unclear. Intuitively, humans have a dimmer-switch model of consciousness – with e.g. ants and worms subsisting with minimal consciousness and humans at the pinnacle of the Great Chain of Being. Yet Darwinian humans may resemble sleepwalkers compared to our fourth-millennium successors. Today we say we’re “awake”, but mankind doesn’t understand what “posthuman intensity of experience” really means.

7) Reversible mind-melding.

Early in the twenty-first century, perhaps the only people who know what it’s like even partially to share a mind are the conjoined Hogan sisters. Tatiana and Krista Hogan share a thalamic bridge. Even mirror-touch synaesthetes can’t literally experience the pains and pleasures of other sentient beings. But in the year 3000, cross-species mind-melding technologies – for instance, sophisticated analogues of reversible thalamic bridges – and digital analogs of telepathy have led to a revolution in both ethics and decision-theoretic rationality.

8) The Anti-Speciesist Revolution / worldwide veganism/invitrotarianism.

Factory-farms, slaughterhouses and other Darwinian crimes against sentience have passed into the dustbin of history. Omnipresent AI cares for the vulnerable via “high-tech Jainism”. The Anti-Speciesist Revolution has made arbitrary prejudice against other sentient beings on grounds of species membership as perversely unthinkable as discrimination on grounds of ethnic group. Sentience is valued more than sapience, the prerogative of classical digital zombies (“robots”).

9) Programmable biospheres.

Sentient beings help rather than harm each other. The successors of today’s primitive CRISPR genome-editing and synthetic gene drive technologies have reworked the global ecosystem. Darwinian life was nasty, brutish and short. Extreme violence and useless suffering were endemic. In the year 3000, fertility regulation via cross-species immunocontraception has replaced predation, starvation and disease to regulate ecologically sustainable population sizes in utopian “wildlife parks”. The free-living descendants of “charismatic mega-fauna” graze happily with neo-dinosaurs, self-replicating nanobots, and newly minted exotica in surreal garden of edens. Every cubic metre of the biosphere is accessible to benign supervision – “nanny AI” for humble minds who haven’t been neurochipped for superintelligence. Other idyllic biospheres in the Solar System have been programmed from scratch.

10) The formalism of the TOE is known.
(details omitteddoes Quora support LaTeX?)

Dirac recognised the superposition principle as the fundamental principle of quantum mechanics. Wavefunction monists believe the superposition principle holds the key to reality itself. However – barring the epoch-making discovery of a cosmic Rosetta stone – the implications of some of the more interesting solutions of the master equation for subjective experience are still unknown.

11) The Hard Problem of consciousness is solved.

The Hard Problem of consciousness was long reckoned insoluble. The Standard Model in physics from which (almost) all else springs was a bit of a mess but stunningly empirically successful at sub-Planckian energy regimes. How could physicalism and the ontological unity of science be reconciled with the existence, classically impossible binding, causal-functional efficacy and diverse palette of phenomenal experience? Mankind’s best theory of the world was inconsistent with one’s own existence, a significant shortcoming. However, all classical- and quantum-mind conjectures with predictive power had been empirically falsified by 3000 – with one exception.

12) The Meaning of Life resolved.

Everyday life is charged with a profound sense of meaning and significance. Everyone feels valuable and valued. Contrast the way twenty-first century depressives typically found life empty, absurd or meaningless; and how even “healthy” normals were sometimes racked by existential angst. Or conversely, compare how people with bipolar disorder experienced megalomania and messianic delusions when uncontrollably manic. Hyperthymic civilization in the year 3000 records no such pathologies of mind or deficits in meaning. Genetically preprogrammed gradients of invincible bliss ensure that all sentient beings find life self-intimatingly valuable. Transhumans love themselves, love life, and love each other.

13) Beautiful new emotions.

Nasty human emotions have been retired – with or without the recruitment of functional analogs to play their former computational role. Novel emotions have been biologically synthesised and their “raw feels” encephalised and integrated into the CNS. All emotion is beautiful. The pleasure axis has replaced the pleasure-pain axis as the engine of civilised life.

14) Effectively unlimited material abundance / molecular nanotechnology.

Status goods long persisted in basement reality, as did relics of the cash nexus on the blockchain. Yet in a world where both computational resources and the substrates of pure bliss aren’t rationed, such ugly evolutionary hangovers first withered, then died.
http://metamodern.com/about-the-author/
Blockchain – Wikipedia

15) Posthuman aesthetics / superhuman beauty.

The molecular signatures of aesthetic experience have been identified, purified and overexpressed. Life is saturated with superhuman beauty. What passed for “Great Art” in the Darwinian era is no more impressive than year 2000 humans might judge, say, a child’s painting by numbers or Paleolithic daubings and early caveporn. Nonetheless, critical discernment is retained. Transhumans are blissful but not “blissed out” – or not all of them at any rate.
Art – Wikipedia
http://www.sciencemag.org/news/2009/05/earliest-pornography

16) Gender transformation.

Like gills or a tail, “gender” in the human sense is a thing of the past. We might call some transhuman minds hyper-masculine (the “ultrahigh AQ” hyper-systematisers), others hyperfeminine (“ultralow AQ” hyper-empathisers), but transhuman cognitive styles transcend such crude dichotomies, and can be shifted almost at will via embedded AI. Many transhumans are asexual, others pan-sexual, a few hypersexual, others just sexually inquisitive. “The degree and kind of a man’s sexuality reach up into the ultimate pinnacle of his spirit”, said Nietzsche – which leads to (17).

https://www.wired.com/2001/12/aqtest/

17) Physical superhealth.

In 3000, everyone feels physically and psychologically “better than well”. Darwinian pathologies of the flesh such as fatigue, the “leaden paralysis” of chronic depressives, and bodily malaise of any kind are inconceivable. The (comparatively) benign “low pain” alleles of the SCN9A gene that replaced their nastier ancestral cousins have been superseded by AI-based nociception with optional manual overrides. Multi-sensory bodily “superpowers” are the norm. Everyone loves their body-images in virtual and basement reality alike. Morphological freedom is effectively unbounded. Awesome robolovers, nights of superhuman sensual passion, 48-hour whole-body orgasms, and sexual practices that might raise eyebrows among prudish Darwinians have multiplied. Yet life isn’t a perpetual orgy. Academic subcultures pursue analogues of Mill’s “higher pleasures”. Paradise engineering has become a rigorous discipline. That said, a lot of transhumans are hedonists who essentially want to have superhuman fun. And why not?

http://www.bbc.com/future/story/20140321-orgasms-at-the-push-of-a-button

18) World government.

Routine policy decisions in basement reality have been offloaded to ultra-intelligent zombie AI. The quasi-psychopathic relationships of Darwinian life – not least the zero-sum primate status-games of the African savannah – are ancient history. Some conflict-resolution procedures previously off-loaded to AI have been superseded by diplomatic “mind-melds”. In the words of Henry Wadsworth Longfellow, “If we could read the secret history of our enemies, we should find in each man’s life sorrow and suffering enough to disarm all hostility.” Our descendants have windows into each other’s souls, so to speak.

19) Historical amnesia.

The world’s last experience below “hedonic zero” marked a major evolutionary transition in the evolutionary development of life. In 3000, the nature of sub-zero states below Sidgwick’s “natural watershed” isn’t understood except by analogy: some kind of phase transition in consciousness below life’s lowest hedonic floor – a hedonic floor that is being genetically ratcheted upwards as life becomes ever more wonderful. Transhumans are hyper-empathetic. They get off on each other’s joys. Yet paradoxically, transhuman mental superhealth depends on biological immunity to true comprehension of the nasty stuff elsewhere in the universal wavefunction that even mature superintelligence is impotent to change. Maybe the nature of e.g. Darwinian life, and the minds of malaise-ridden primitives in inaccessible Everett branches, doesn’t seem any more interesting than we find books on the Dark Ages. Negative utilitarianism, if it were conceivable, might be viewed as a depressive psychosis. “Life is suffering”, said Gautama Buddha, but fourth millennials feel in the roots of their being that Life is bliss.
Invincible ignorance? Perhaps.
Negative Utilitarianism – Wikipedia

20) Super-spirituality.

A tough one to predict. But neuroscience can soon identify the molecular signatures of spiritual experience, refine them, and massively amplify their molecular substrates. Perhaps some fourth millennials enjoy lifelong spiritual ecstasies beyond the mystical epiphanies of temporal-lobe epileptics. Secular rationalists don’t know what we’re missing.

21) The Reproductive Revolution.
Reproduction is uncommon in a post-aging society. Most transhumans originate as extra-uterine “designer babies”. The reckless genetic experimentation of sexual reproduction had long seemed irresponsible. Old habits still died hard. By year 3000, the genetic crapshoot of Darwinian life has finally been replaced by precision-engineered sentience. Early critics of “eugenics” and a “Brave New World” have discovered by experience that a “triple S” civilisation of superhappiness, superlongevity and superintelligence isn’t as bad as they supposed.
https://www.reproductive-revolution.com/
https://www.huxley.net/

22) Globish (“English Plus”).

Automated real-time translation has been superseded by a common tongue – Globish – spoken, written or “telepathically” communicated. Partial translation manuals for mutually alien state-spaces of consciousness exist, but – as twentieth century Kuhnians would have put it – such state-spaces tend to be incommensurable and their concepts state-specific. Compare how poorly lucid dreamers can communicate with “awake” humans. Many Darwinian terms and concepts are effectively obsolete. In their place, active transhumanist vocabularies of millions of words are common. “Basic Globish” is used for communication with humble minds, i.e. human and nonhuman animals who haven’t been fully uplifted.
Incommensurability – SEoP
Uplift (science_fiction) – Wikipedia

23) Plans for Galactic colonization.

Terraforming and 3D-bioprinting of post-Darwinian life on nearby solar systems is proceeding apace. Vacant ecological niches tend to get filled. In earlier centuries, a synthesis of cryonics, crude reward pathway enhancements and immersive VR software, combined with revolutionary breakthroughs in rocket propulsion, led to the launch of primitive manned starships. Several are still starbound. Some transhuman utilitarian ethicists and policy-makers favour creating a utilitronium shockwave beyond the pale of civilisation to convert matter and energy into pure pleasure. Year 3000 bioconservatives focus on promoting life animated by gradients of superintelligent bliss. Yet no one objects to pure “hedonium” replacing unprogrammed matter.
Interstellar Travel – Wikipedia
Utilitarianism – Wikipedia

24) The momentous “unknown unknown”.

If you read a text and the author’s last words are “and then I woke up”, everything you’ve read must be interpreted in a new light – semantic holism with a vengeance. By the year 3000, some earth-shattering revelation may have changed everything – some fundamental background assumption of earlier centuries has been overturned that might not have been explicitly represented in our conceptual scheme. If it exists, then I’ve no inkling what this “unknown unknown” might be, unless it lies hidden in the untapped subjective properties of matter and energy. Christian readers might interject “The Second Coming”. Learning the Simulation Hypothesis were true would be a secular example of such a revelation. Some believers in an AI “Intelligence Explosion” speak delphically of “The Singularity”. Whatever – Shakespeare made the point more poetically, “There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy”.

As it stands, yes, (24) is almost vacuous. Yet compare how the philosophers of classical antiquity who came closest to recognising their predicament weren’t intellectual titans like Plato or Aristotle, but instead the radical sceptics. The sceptics guessed they were ignorant in ways that transcended the capacity of their conceptual scheme to articulate. By the lights of the fourth millennium, what I’m writing, and what you’re reading, may be stultified by something that humans don’t know and can’t express.

**********************************************************************

OK, twenty-four predictions! Successful prophets tend to locate salvation or doom within the credible lifetime of their intended audience. The questioner asks about life in the year 3000 rather than, say, a Kurzweilian 2045. In my view, everyone reading this text will grow old and die before the predictions of this answer are realised or confounded – with one possible complication.

Opt-out cryonics and opt-in cryothanasia are feasible long before the conquest of aging. Visiting grandpa in the cryonics facility can turn death into an event in life. I’m not convinced that posthuman superintelligence will reckon that Darwinian malware should be revived in any shape or form. Yet if you want to wake up one morning in posthuman paradise – and I do see the appeal – then options exist:

Why I think the Foundational Research Institute should rethink its approach

by Mike Johnson

The following is my considered evaluation of the Foundational Research Institute, circa July 2017. I discuss its goal, where I foresee things going wrong with how it defines suffering, and what it could do to avoid these problems.

TL;DR version: functionalism (“consciousness is the sum-total of the functional properties of our brains”) sounds a lot better than it actually turns out to be in practice. In particular, functionalism makes it impossible to define ethics & suffering in a way that can mediate disagreements.

I. What is the Foundational Research Institute?

The Foundational Research Institute (FRI) is a Berlin-based group that “conducts research on how to best reduce the suffering of sentient beings in the near and far future.” Executive Director Max Daniel introduced them at EA Global Boston as “the only EA organization which at an organizational level has the mission of focusing on reducing s-risk.” S-risks are, according to Daniel, “risks where an adverse outcome would bring about suffering on an astronomical scale, vastly exceeding all suffering that has existed on Earth so far.”

Essentially, FRI wants to become the research arm of suffering-focused ethics, and help prevent artificial general intelligence (AGI) failure-modes which might produce suffering on a cosmic scale.

What I like about FRI:

While I have serious qualms about FRI’s research framework, I think the people behind FRI deserve a lot of credit- they seem to be serious people, working hard to build something good. In particular, I want to give them a shoutout for three things:

  • First, FRI takes suffering seriously, and I think that’s important. When times are good, we tend to forget how tongue-chewingly horrific suffering can be. S-risks seem particularly horrifying.
  • Second, FRI isn’t afraid of being weird. FRI has been working on s-risk research for a few years now, and if people are starting to come around to the idea that s-risks are worth thinking about, much of the credit goes to FRI.
  • Third, I have great personal respect for Brian Tomasik, one of FRI’s co-founders. I’ve found him highly thoughtful, generous in debates, and unfailingly principled. In particular, he’s always willing to bite the bullet and work ideas out to their logical end, even if it involves repugnant conclusions.

What is FRI’s research framework?

FRI believes in analytic functionalism, or what David Chalmers calls “Type-A materialism”. Essentially, what this means is there’s no ’theoretical essence’ to consciousness; rather, consciousness is the sum-total of the functional properties of our brains. Since ‘functional properties’ are rather vague, this means consciousness itself is rather vague, in the same way words like “life,” “justice,” and “virtue” are messy and vague.

Brian suggests that this vagueness means there’s an inherently subjective, perhaps arbitrary element to how we define consciousness:

Analytic functionalism looks for functional processes in the brain that roughly capture what we mean by words like “awareness”, “happy”, etc., in a similar way as a biologist may look for precise properties of replicators that roughly capture what we mean by “life”. Just as there can be room for fuzziness about where exactly to draw the boundaries around “life”, different analytic functionalists may have different opinions about where to define the boundaries of “consciousness” and other mental states. This is why consciousness is “up to us to define”. There’s no hard problem of consciousness for the same reason there’s no hard problem of life: consciousness is just a high-level word that we use to refer to lots of detailed processes, and it doesn’t mean anything in addition to those processes.

Finally, Brian argues that the phenomenology of consciousness is identical with the phenomenology of computation:

I know that I’m conscious. I also know, from neuroscience combined with Occam’s razor, that my consciousness consists only of material operations in my brain — probably mostly patterns of neuronal firing that help process inputs, compute intermediate ideas, and produce behavioral outputs. Thus, I can see that consciousness is just the first-person view of certain kinds of computations — as Eliezer Yudkowsky puts it, “How An Algorithm Feels From Inside“. Consciousness is not something separate from or epiphenomenal to these computations. It is these computations, just from their own perspective of trying to think about themselves.

 

In other words, consciousness is what minds compute. Consciousness is the collection of input operations, intermediate processing, and output behaviors that an entity performs.

And if consciousness is all these things, so too is suffering. Which means suffering is computational, yet also inherently fuzzy, and at least a bit arbitrary; a leaky high-level reification impossible to speak about accurately, since there’s no formal, objective “ground truth”.

II. Why do I worry about FRI’s research framework?

In short, I think FRI has a worthy goal and good people, but its metaphysics actively prevent making progress toward that goal. The following describes why I think that, drawing heavily on Brian’s writings (of FRI’s researchers, Brian seems the most focused on metaphysics):

Note: FRI is not the only EA organization which holds functionalist views on consciousness; much of the following critique would also apply to e.g. MIRI, FHI, and OpenPhil. I focus on FRI because (1) Brian’s writings on consciousness & functionalism have been hugely influential in the community, and are clear enough *to* criticize; (2) the fact that FRI is particularly clear about what it cares about- suffering- allows a particularly clear critique about what problems it will run into with functionalism; (3) I believe FRI is at the forefront of an important cause area which has not crystallized yet, and I think it’s critically important to get these objections bouncing around this subcommunity.

Objection 1: Motte-and-bailey

Brian: “Consciousness is not a thing which exists ‘out there’ or even a separate property of matter; it’s a definitional category into which we classify minds. ‘Is this digital mind really conscious?’ is analogous to ‘Is a rock that people use to eat on really a table?’ [However,] That consciousness is a cluster in thingspace rather than a concrete property of the world does not make reducing suffering less important.”

The FRI model seems to imply that suffering is ineffable enough such that we can’t have an objective definition, yet sufficiently effable that we can coherently talk and care about it. This attempt to have it both ways seems contradictory, or at least in deep tension.

Indeed, I’d argue that the degree to which you can care about something is proportional to the degree to which you can define it objectively. E.g., If I say that “gnireffus” is literally the most terrible thing in the cosmos, that we should spread gnireffus-focused ethics, and that minimizing g-risks (far-future scenarios which involve large amounts of gnireffus) is a moral imperative, but also that what is and what and isn’t gnireffus is rather subjective with no privileged definition, and it’s impossible to objectively tell if a physical system exhibits gnireffus, you might raise any number of objections. This is not an exact metaphor for FRI’s position, but I worry that FRI’s work leans on the intuition that suffering is real and we can speak coherently about it, to a degree greater than its metaphysics formally allow.

Max Daniel (personal communication) suggests that we’re comfortable with a degree of ineffability in other contexts; “Brian claims that the concept of suffering shares the allegedly problematic properties with the concept of a table. But it seems a stretch to say that the alleged tension is problematic when talking about tables. So why would it be problematic when talking about suffering?” However, if we take the anti-realist view that suffering is ‘merely’ a node in the network of language, we have to live with the consequences of this: that ‘suffering’ will lose meaning as we take it away from the network in which it’s embedded (Wittgenstein). But FRI wants to do exactly this, to speak about suffering in the context of AGIs, simulated brains, even video game characters.

We can be anti-realists about suffering (suffering-is-a-node-in-the-network-of-language), or we can argue that we can talk coherently about suffering in novel contexts (AGIs, mind crime, aliens, and so on), but it seems inherently troublesome to claim we can do both at the same time.

Objection 2: Intuition duels

Two people can agree on FRI’s position that there is no objective fact of the matter about what suffering is (no privileged definition), but this also means they have no way of coming to any consensus on the object-level question of whether something can suffer. This isn’t just an academic point: Brian has written extensively about how he believes non-human animals can and do suffer extensively, whereas Yudkowsky (who holds computationalist views, like Brian) has written about how he’s confident that animals are not conscious and cannot suffer, due to their lack of higher-order reasoning.

And if functionalism is having trouble adjudicating the easy cases of suffering–whether monkeys can suffer, or whether dogs can— it doesn’t have a sliver of a chance at dealing with the upcoming hard cases of suffering: whether a given AGI is suffering, or engaging in mind crime; whether a whole-brain emulation (WBE) or synthetic organism or emergent intelligence that doesn’t have the capacity to tell us how it feels (or that we don’t have the capacity to understand) is suffering; if any aliens that we meet in the future can suffer; whether changing the internal architecture of our qualia reports means we’re also changing our qualia; and so on.

In short, FRI’s theory of consciousness isn’t actually a theory of consciousness at all, since it doesn’t do the thing we need a theory of consciousness to do: adjudicate disagreements in a principled way. Instead, it gives up any claim on the sorts of objective facts which could in principle adjudicate disagreements.

This is a source of friction in EA today, but it’s mitigated by the sense that

(1) The EA pie is growing, so it’s better to ignore disagreements than pick fights;

(2) Disagreements over the definition of suffering don’t really matter yet, since we haven’t gotten into the business of making morally-relevant synthetic beings (that we know of) that might be unable to vocalize their suffering.

If the perception of one or both of these conditions change, the lack of some disagreement-adjudicating theory of suffering will matter quite a lot.

Objection 3: Convergence requires common truth

Mike: “[W]hat makes one definition of consciousness better than another? How should we evaluate them?”

Brian: “Consilience among our feelings of empathy, principles of non-discrimination, understandings of cognitive science, etc. It’s similar to the question of what makes one definition of justice or virtue better than another.”

Brian is hoping that affective neuroscience will slowly converge to accurate views on suffering as more and better data about sentience and pain accumulates. But convergence to truth implies something (objective) driving the convergence- in this way, Brian’s framework still seems to require an objective truth of the matter, even though he disclaims most of the benefits of assuming this.

Objection 4: Assuming that consciousness is a reification produces more confusion, not less

Brian: “Consciousness is not a reified thing; it’s not a physical property of the universe that just exists intrinsically. Rather, instances of consciousness are algorithms that are implemented in specific steps. … Consciousness involves specific things that brains do.”

Brian argues that we treat conscious/phenomenology as more ‘real’ than it is. Traditionally, whenever we’ve discovered something is a leaky reification and shouldn’t be treated as ‘too real’, we’ve been able to break it down into more coherent constituent pieces we can treat as real. Life, for instance, wasn’t due to élan vital but a bundle of self-organizing properties & dynamics which generally co-occur. But carrying out this “de-reification” process on consciousness– enumerating its coherent constituent pieces– has proven difficult, especially if we want to preserve some way to speak cogently about suffering.

Speaking for myself, the more I stared into the depths of functionalism, the less certain everything about moral value became– and arguably, I see the same trajectory in Brian’s work and Luke Muehlhauser’s report. Their model uncertainty has seemingly become larger as they’ve looked into techniques for how to “de-reify” consciousness while preserving some flavor of moral value, not smaller. Brian and Luke seem to interpret this as evidence that moral value is intractably complicated, but this is also consistent with consciousness not being a reification, and instead being a real thing. Trying to “de-reify” something that’s not a reification will produce deep confusion, just as surely trying to treat a reification as ‘more real’ than it actually is will.

Edsger W. Dijkstra famously noted that “The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise.” And so if our ways of talking about moral value fail to ‘carve reality at the joints’- then by all means let’s build better ones, rather than giving up on precision.

Objection 5: The Hard Problem of Consciousness is a red herring

Brian spends a lot of time discussing Chalmers’ “Hard Problem of Consciousness”, i.e. the question of why we’re subjectively conscious, and seems to base at least part of his conclusion on not finding this question compelling— he suggests “There’s no hard problem of consciousness for the same reason there’s no hard problem of life: consciousness is just a high-level word that we use to refer to lots of detailed processes, and it doesn’t mean anything in addition to those processes.” I.e., no ‘why’ is necessary; when we take consciousness and subtract out the details of the brain, we’re left with an empty set.

But I think the “Hard Problem” isn’t helpful as a contrastive centerpiece, since it’s unclear what the problem is, and whether it’s analytic or empirical, a statement about cognition or about physics. At the Qualia Research Institute (QRI), we don’t talk much about the Hard Problem; instead, we talk about Qualia Formalism, or the idea that any phenomenological state can be crisply and precisely represented by some mathematical object. I suspect this would be a better foil for Brian’s work than the Hard Problem.

Objection 6: Mapping to reality

Brian argues that consciousness should be defined at the functional/computational level: given a Turing machine, or neural network, the right ‘code’ will produce consciousness. But the problem is that this doesn’t lead to a theory which can ‘compile’ to physics. Consider the following:

Imagine you have a bag of popcorn. Now shake it. There will exist a certain ad-hoc interpretation of bag-of-popcorn-as-computational-system where you just simulated someone getting tortured, and other interpretations that don’t imply that. Did you torture anyone? If you’re a computationalist, no clear answer exists- you both did, and did not, torture someone. This sounds like a ridiculous edge-case that would never come up in real life, but in reality it comes up all the time, since there is no principled way to *objectively derive* what computation(s) any physical system is performing.

I don’t think this is an outlandish view of functionalism; Brian suggests much the same in How to Interpret a Physical System as a Mind“Physicalist views that directly map from physics to moral value are relatively simple to understand. Functionalism is more complex, because it maps from physics to computations to moral value. Moreover, while physics is real and objective, computations are fictional and ‘observer-relative’ (to use John Searle’s terminology). There’s no objective meaning to ‘the computation that this physical system is implementing’ (unless you’re referring to the specific equations of physics that the system is playing out).”

Gordon McCabe (McCabe 2004) provides a more formal argument to this effect— that precisely mapping between physical processes and (Turing-level) computational processes is inherently impossible— in the context of simulations. First, McCabe notes that:

[T]here is a one-[to-]many correspondence between the logical states [of a computer] and the exact electronic states of computer memory. Although there are bijective mappings between numbers and the logical states of computer memory, there are no bijective mappings between numbers and the exact electronic states of memory.

This lack of an exact bijective mapping means that subjective interpretation necessarily creeps in, and so a computational simulation of a physical system can’t be ‘about’ that system in any rigorous way:

In a computer simulation, the values of the physical quantities possessed by the simulated system are represented by the combined states of multiple bits in computer memory. However, the combined states of multiple bits in computer memory only represent numbers because they are deemed to do so under a numeric interpretation. There are many different interpretations of the combined states of multiple bits in computer memory. If the numbers represented by a digital computer are interpretation-dependent, they cannot be objective physical properties. Hence, there can be no objective relationship between the changing pattern of multiple bit-states in computer memory, and the changing pattern of quantity-values of a simulated physical system.

McCabe concludes that, metaphysically speaking,

A digital computer simulation of a physical system cannot exist as, (does not possess the properties and relationships of), anything else other than a physical process occurring upon the components of a computer. In the contemporary case of an electronic digital computer, a simulation cannot exist as anything else other than an electronic physical process occurring upon the components and circuitry of a computer.

Where does this leave ethics? In Flavors of Computation Are Flavors of Consciousness, Brian notes that “In some sense all I’ve proposed here is to think of different flavors of computation as being various flavors of consciousness. But this still leaves the question: Which flavors of computation matter most? Clearly whatever computations happen when a person is in pain are vastly more important than what’s happening in a brain on a lazy afternoon. How can we capture that difference?”

But if Brian grants the former point- that “There’s no objective meaning to ‘the computation that this physical system is implementing’”– then this latter task of figuring out “which flavors of computation matter most” is provably impossible. There will always be multiple computational (and thus ethical) interpretations of a physical system, with no way to figure out what’s “really” happening. No way to figure out if something is suffering or not. No consilience; not now, not ever.

Note: despite apparently granting the point above, Brian also remarks that:

I should add a note on terminology: All computations occur within physics, so any computation is a physical process. Conversely, any physical process proceeds from input conditions to output conditions in a regular manner and so is a computation. Hence, the set of computations equals the set of physical processes, and where I say “computations” in this piece, one could just as well substitute “physical processes” instead.

This seems to be (1) incorrect, for the reasons I give above, or (2) taking substantial poetic license with these terms, or (3) referring to hypercomputation (which might be able to salvage the metaphor, but would invalidate many of FRI’s conclusions dealing with the computability of suffering on conventional hardware).

This objection may seem esoteric or pedantic, but I think it’s important, and that it ripples through FRI’s theoretical framework with disastrous effects.

 

Objection 7: FRI doesn’t fully bite the bullet on computationalism

Brian suggests that “flavors of computation are flavors of consciousness” and that some computations ‘code’ for suffering. But if we do in fact bite the bullet on this metaphor and place suffering within the realm of computational theory, we need to think in “near mode” and accept all the paradoxes that brings. Scott Aaronson, a noted expert on quantum computing, raises the following objections to functionalism:

I’m guessing that many people in this room side with Dennett, and (not coincidentally, I’d say) also with Everett. I certainly have sympathies in that direction too. In fact, I spent seven or eight years of my life as a Dennett/Everett hardcore believer. But, while I don’t want to talk anyone out of the Dennett/Everett view, I’d like to take you on a tour of what I see as some of the extremely interesting questions that that view leaves unanswered. I’m not talking about “deep questions of meaning,” but about something much more straightforward: what exactly does a computational process have to do to qualify as “conscious”?

 

 

There’s this old chestnut, what if each person on earth simulated one neuron of your brain, by passing pieces of paper around. It took them several years just to simulate a single second of your thought processes. Would that bring your subjectivity into being? Would you accept it as a replacement for your current body? If so, then what if your brain were simulated, not neuron-by-neuron, but by a gigantic lookup table? That is, what if there were a huge database, much larger than the observable universe (but let’s not worry about that), that hardwired what your brain’s response was to every sequence of stimuli that your sense-organs could possibly receive. Would that bring about your consciousness? Let’s keep pushing: if it would, would it make a difference if anyone actually consulted the lookup table? Why can’t it bring about your consciousness just by sitting there doing nothing?

To these standard thought experiments, we can add more. Let’s suppose that, purely for error-correction purposes, the computer that’s simulating your brain runs the code three times, and takes the majority vote of the outcomes. Would that bring three “copies” of your consciousness into being? Does it make a difference if the three copies are widely separated in space or time—say, on different planets, or in different centuries? Is it possible that the massive redundancy taking place in your brain right now is bringing multiple copies of you into being?

 

 

Maybe my favorite thought experiment along these lines was invented by my former student Andy Drucker.  In the past five years, there’s been a revolution in theoretical cryptography, around something called Fully Homomorphic Encryption (FHE), which was first discovered by Craig Gentry.  What FHE lets you do is to perform arbitrary computations on encrypted data, without ever decrypting the data at any point.  So, to someone with the decryption key, you could be proving theorems, simulating planetary motions, etc.  But to someone without the key, it looks for all the world like you’re just shuffling random strings and producing other random strings as output.

 

You can probably see where this is going.  What if we homomorphically encrypted a simulation of your brain?  And what if we hid the only copy of the decryption key, let’s say in another galaxy?  Would this computation—which looks to anyone in our galaxy like a reshuffling of gobbledygook—be silently producing your consciousness?

 

When we consider the possibility of a conscious quantum computer, in some sense we inherit all the previous puzzles about conscious classical computers, but then also add a few new ones.  So, let’s say I run a quantum subroutine that simulates your brain, by applying some unitary transformation U.  But then, of course, I want to “uncompute” to get rid of garbage (and thereby enable interference between different branches), so I apply U-1.  Question: when I apply U-1, does your simulated brain experience the same thoughts and feelings a second time?  Is the second experience “the same as” the first, or does it differ somehow, by virtue of being reversed in time? Or, since U-1U is just a convoluted implementation of the identity function, are there no experiences at all here?

 

Here’s a better one: many of you have heard of the Vaidman bomb.  This is a famous thought experiment in quantum mechanics where there’s a package, and we’d like to “query” it to find out whether it contains a bomb—but if we query it and there is a bomb, it will explode, killing everyone in the room.  What’s the solution?  Well, suppose we could go into a superposition of querying the bomb and not querying it, with only ε amplitude on querying the bomb, and √(1-ε2) amplitude on not querying it.  And suppose we repeat this over and over—each time, moving ε amplitude onto the “query the bomb” state if there’s no bomb there, but moving ε2 probability onto the “query the bomb” state if there is a bomb (since the explosion decoheres the superposition).  Then after 1/ε repetitions, we’ll have order 1 probability of being in the “query the bomb” state if there’s no bomb.  By contrast, if there is a bomb, then the total probability we’ve ever entered that state is (1/ε)×ε2 = ε.  So, either way, we learn whether there’s a bomb, and the probability that we set the bomb off can be made arbitrarily small.  (Incidentally, this is extremely closely related to how Grover’s algorithm works.)

 

OK, now how about the Vaidman brain?  We’ve got a quantum subroutine simulating your brain, and we want to ask it a yes-or-no question.  We do so by querying that subroutine with ε amplitude 1/ε times, in such a way that if your answer is “yes,” then we’ve only ever activated the subroutine with total probability ε.  Yet you still manage to communicate your “yes” answer to the outside world.  So, should we say that you were conscious only in the ε fraction of the wavefunction where the simulation happened, or that the entire system was conscious?  (The answer could matter a lot for anthropic purposes.)

To sum up: Brian’s notion that consciousness is the same as computation raises more issues than it solves; in particular, the possibility that if suffering is computable, it may also be uncomputable/reversible, would suggest s-risks aren’t as serious as FRI treats them.

Objection 8: Dangerous combination

Three themes which seem to permeate FRI’s research are:

(1) Suffering is the thing that is bad.

(2) It’s critically important to eliminate badness from the universe.

(3) Suffering is impossible to define objectively, and so we each must define what suffering means for ourselves.

Taken individually, each of these seems reasonable. Pick two, and you’re still okay. Pick all three, though, and you get A Fully General Justification For Anything, based on what is ultimately a subjective/aesthetic call.

Much can be said in FRI’s defense here, and it’s unfair to single them out as risky: in my experience they’ve always brought a very thoughtful, measured, cooperative approach to the table. I would just note that ideas are powerful, and I think theme (3) is especially pernicious if incorrect.

III. QRI’s alternative

Analytic functionalism is essentially a negative hypothesis about consciousness: it’s the argument that there’s no order to be found, no rigor to be had. It obscures this with talk of “function”, which is a red herring it not only doesn’t define, but admits is undefinable. It doesn’t make any positive assertion. Functionalism is skepticism- nothing more, nothing less.

But is it right?

Ultimately, I think these a priori arguments are much like people in the middle ages arguing whether one could ever formalize a Proper System of Alchemy. Such arguments may in many cases hold water, but it’s often difficult to tell good arguments apart from arguments where we’re just cleverly fooling ourselves. In retrospect, the best way to *prove* systematized alchemy was possible was to just go out and *do* it, and invent Chemistry. That’s how I see what we’re doing at QRI with Qualia Formalism: we’re assuming it’s possible to build stuff, and we’re working on building the object-level stuff.

What we’ve built with QRI’s framework

Note: this is a brief, surface-level tour of our research; it will probably be confusing for readers who haven’t dug into our stuff before. Consider this a down-payment on a more substantial introduction.

My most notable work is Principia Qualia, in which I lay out my meta-framework for consciousness (a flavor of dual-aspect monism, with a focus on Qualia Formalism) and put forth the Symmetry Theory of Valence (STV). Essentially, the STV is an argument that much of the apparent complexity of emotional valence is evolutionarily contingent, and if we consider a mathematical object isomorphic to a phenomenological experience, the mathematical property which corresponds to how pleasant it is to be that experience is the object’s symmetry. This implies a bunch of testable predictions and reinterpretations of things like what ‘pleasure centers’ do (Section XI; Section XII). Building on this, I offer the Symmetry Theory of Homeostatic Regulation, which suggests understanding the structure of qualia will translate into knowledge about the structure of human intelligence, and I briefly touch on the idea of Neuroacoustics.

Likewise, my colleague Andrés Gómez Emilsson has written about the likely mathematics of phenomenology, including The Hyperbolic Geometry of DMT Experiences, Tyranny of the Intentional Object, and Algorithmic Reduction of Psychedelic States. If I had to suggest one thing to read in all of these links, though, it would be the transcript of his recent talk on Quantifying Bliss, which lays out the world’s first method to objectively measure valence from first principles (via fMRI) using Selen Atasoy’s Connectome Harmonics framework, the Symmetry Theory of Valence, and Andrés’s CDNS model of experience.

These are risky predictions and we don’t yet know if they’re right, but we’re confident that if there is some elegant structure intrinsic to consciousness, as there is in many other parts of the natural world, these are the right kind of risks to take.

I mention all this because I think analytic functionalism- which is to say radical skepticism/eliminativism, the metaphysics of last resort- only looks as good as it does because nobody’s been building out any alternatives.

IV. Closing thoughts

FRI is pursuing a certain research agenda, and QRI is pursuing another, and there’s lots of value in independent explorations of the nature of suffering. I’m glad FRI exists, everybody I’ve interacted with at FRI has been great, I’m happy they’re focusing on s-risks, and I look forward to seeing what they produce in the future.

On the other hand, I worry that nobody’s pushing back on FRI’s metaphysics, which seem to unavoidably lead to the intractable problems I describe above. FRI seems to believe these problems are part of the territory, unavoidable messes that we just have to make philosophical peace with. But I think that functionalism is a bad map, that the metaphysical messes it leads to are much worse than most people realize (fatal to FRI’s mission), and there are other options that avoid these problems (which, to be fair, is not to say they have no problems).

Ultimately, FRI doesn’t owe me a defense of their position. But if they’re open to suggestions on what it would take to convince a skeptic like me that their brand of functionalism is viable, or at least rescuable, I’d offer the following:

Re: Objection 1 (motte-and-bailey), I suggest FRI should be as clear and complete as possible in their basic definition of suffering. In which particular ways is it ineffable/fuzzy, and in which particular ways is it precise? What can we definitely say about suffering, and what can we definitely never determine? Preregistering ontological commitments and methodological possibilities would help guard against FRI’s definition of suffering changing based on context.

Re: Objection 2 (intuition duels), FRI may want to internally “war game” various future scenarios involving AGI, WBE, etc, with one side arguing that a given synthetic (or even extraterrestrial) organism is suffering, and the other side arguing that it isn’t. I’d expect this would help diagnose what sorts of disagreements future theories of suffering will need to adjudicate, and perhaps illuminate implicit ethical intuitions. Sharing the results of these simulated disagreements would also be helpful in making FRI’s reasoning less opaque to outsiders, although making everything transparent could lead to certain strategic disadvantages.

Re: Objection 3 (convergence requires common truth), I’d like FRI to explore exactly what might drive consilience/convergence in theories of suffering, and what precisely makes one theory of suffering better than another, and ideally to evaluate a range of example theories of suffering under these criteria.

Re: Objection 4 (assuming that consciousness is a reification produces more confusion, not less), I would love to see a historical treatment of reification: lists of reifications which were later dissolved (e.g., élan vital), vs scattered phenomena that were later unified (e.g., electromagnetism). What patterns do the former have, vs the latter, and why might consciousness fit one of these buckets better than the other?

Re: Objection 5 (the Hard Problem of Consciousness is a red herring), I’d like to see a more detailed treatment of what kinds of problem people have interpreted the Hard Problem as, and also more analysis on the prospects of Qualia Formalism (which I think is the maximally-empirical, maximally-charitable interpretation of the Hard Problem). It would be helpful for us, in particular, if FRI preregistered their expectations about QRI’s predictions, and their view of the relative evidence strength of each of our predictions.

Re: Objection 6 (mapping to reality), this is perhaps the heart of most of our disagreement. From Brian’s quotes, he seems split on this issue; I’d like clarification about whether he believes we can ever precisely/objectively map specific computations to specific physical systems, and vice-versa. And if so— how? If not, this seems to propagate through FRI’s ethical framework in a disastrous way, since anyone can argue that any physical system does, or does not, ‘code’ for massive suffering, and there’s no principled way to derive any ‘ground truth’ or even pick between interpretations in a principled way (e.g. my popcorn example). If this isn’t the case— why not?

Brian has suggested that “certain high-level interpretations of physical systems are more ‘natural’ and useful than others” (personal communication); I agree, and would encourage FRI to explore systematizing this.

It would be non-trivial to port FRI’s theories and computational intuitions to the framework of “hypercomputation”– i.e., the understanding that there’s a formal hierarchy of computational systems, and that Turing machines are only one level of many– but it may have benefits too. Namely, it might be the only way they could avoid Objection 6 (which I think is a fatal objection) while still allowing them to speak about computation & consciousness in the same breath. I think FRI should look at this and see if it makes sense to them.

Re: Objection 7 (FRI doesn’t fully bite the bullet on computationalism), I’d like to see responses to Aaronson’s aforementioned thought experiments.

Re: Objection 8 (dangerous combination), I’d like to see a clarification about why my interpretation is unreasonable (as it very well may be!).

 


In conclusion- I think FRI has a critically important goal- reduction of suffering & s-risk. However, I also think FRI has painted itself into a corner by explicitly disallowing a clear, disagreement-mediating definition for what these things are. I look forward to further work in this field.

Principia Qualia: Part II – Valence

Extract from Principia Qualia (2016) by my colleague Michael E. Johnson (from Qualia Research Institute). This is intended to summarize the core ideas of chapter 2, which proposes a precise, testable, simple, and so far science-compatible theory of the fundamental nature of valence (also called hedonic tone or the pleasure-pain axis; what makes experiences feel good or bad).

 

VII. Three principles for a mathematical derivation of valence

We’ve covered a lot of ground with the above literature reviews, and synthesizing a new framework for understanding consciousness research. But we haven’t yet fulfilled the promise about valence made in Section II- to offer a rigorous, crisp, and relatively simple hypothesis about valence. This is the goal of Part II.

Drawing from the framework in Section VI, I offer three principles to frame this problem: ​

1. Qualia Formalism: for any given conscious experience, there exists- in principle- a mathematical object isomorphic to its phenomenology. This is a formal way of saying that consciousness is in principle quantifiable- much as electromagnetism, or the square root of nine is quantifiable. I.e. IIT’s goal, to generate such a mathematical object, is a valid one.

2. Qualia Structuralism: this mathematical object has a rich set of formal structures. Based on the regularities & invariances in phenomenology, it seems safe to say that qualia has a non-trivial amount of structure. It likely exhibits connectedness (i.e., it’s a unified whole, not the union of multiple disjoint sets), and compactness, and so we can speak of qualia as having a topology.

More speculatively, based on the following:

(a) IIT’s output format is data in a vector space,

(b) Modern physics models reality as a wave function within Hilbert Space, which has substantial structure,

(c) Components of phenomenology such as color behave as vectors (Feynman 1965), and

(d) Spatial awareness is explicitly geometric,

…I propose that Qualia space also likely satisfies the requirements of being a metric space, and we can speak of qualia as having a geometry.

Mathematical structures are important, since the more formal structures a mathematical object has, the more elegantly we can speak about patterns within it, and the closer our words can get to “carving reality at the joints”. ​

3. Valence Realism: valence is a crisp phenomenon of conscious states upon which we can apply a measure.

–> I.e. some experiences do feel holistically better than others, and (in principle) we can associate a value to this. Furthermore, to combine (2) and (3), this pleasantness could be encoded into the mathematical object isomorphic to the experience in an efficient way (we should look for a concise equation, not an infinitely-large lookup table for valence). […]

valence_structuralism

I believe my three principles are all necessary for a satisfying solution to valence (and the first two are necessary for any satisfying solution to consciousness):

Considering the inverses:

If Qualia Formalism is false, then consciousness is not quantifiable, and there exists no formal knowledge about consciousness to discover. But if the history of science is any guide, we don’t live in a universe where phenomena are intrinsically unquantifiable- rather, we just haven’t been able to crisply quantify consciousness yet.

If Qualia Structuralism is false and Qualia space has no meaningful structure to discover and generalize from, then most sorts of knowledge about qualia (such as which experiences feel better than others) will likely be forever beyond our empirical grasp. I.e., if Qualia space lacks structure, there will exist no elegant heuristics or principles for interpreting what a mathematical object isomorphic to a conscious experience means. But this doesn’t seem to match the story from affective neuroscience, nor from our everyday experience: we have plenty of evidence for patterns, regularities, and invariances in phenomenological experiences. Moreover, our informal, intuitive models for predicting our future qualia are generally very good. This implies our brains have figured out some simple rules-of-thumb for how qualia is structured, and so qualia does have substantial mathematical structure, even if our formal models lag behind.

If Valence Realism is false, then we really can’t say very much about ethics, normativity, or valence with any confidence, ever. But this seems to violate the revealed preferences of the vast majority of people: we sure behave as if some experiences are objectively superior to others, at arbitrarily-fine levels of distinction. It may be very difficult to put an objective valence on a given experience, but in practice we don’t behave as if this valence doesn’t exist.

[…]

VIII. Distinctions in qualia: charting the explanation space for valence

Sections II-III made the claim that we need a bottom-up quantitative theory like IIT in order to successfully reverse-engineer valence, Section VI suggested some core problems & issues theories like IIT will need to address, and Section VII proposed three principles for interpreting IIT-style output:

  1. We should think of qualia as having a mathematical representation,
  2. This mathematical representation has a topology and probably a geometry, and perhaps more structure, and
  3. Valence is real; some things do feel better than others, and we should try to explain why in terms of qualia’s mathematical representation.

But what does this get us? Specifically, how does assuming these three things get us any closer to solving valence if we don’t have an actual, validated dataset (“data structure isomorphic to the phenomenology”) from *any* system, much less a real brain?

It actually helps a surprising amount, since an isomorphism between a structured (e.g., topological, geometric) space and qualia implies that any clean or useful distinction we can make in one realm automatically applies in the other realm as well. And if we can explore what kinds of distinctions in qualia we can make, we can start to chart the explanation space for valence (what ‘kind’ of answer it will be).

I propose the following four distinctions which depend on only a very small amount of mathematical structure inherent in qualia space, which should apply equally to qualia and to qualia’s mathematical representation:

  1. Global vs local
  2. Simple vs complex
  3. Atomic vs composite
  4. Intuitively important vs intuitively trivial

[…]

Takeaways: this section has suggested that we can get surprising mileage out of the hypothesis that there will exist a geometric data structure isomorphic to the phenomenology of a system, since if we can make a distinction in one domain (math or qualia), it will carry over into the other domain ‘for free’. Given this, I put forth the hypothesis that valence may plausibly be a simple, global, atomic, and intuitively important property of both qualia and its mathematical representation.

IX. Summary of heuristics for reverse-engineering the pattern for valence

Reverse-engineering the precise mathematical property that corresponds to valence may seem like finding a needle in a haystack, but I propose that it may be easier than it appears. Broadly speaking, I see six heuristics for zeroing in on valence:

A. Structural distinctions in Qualia space (Section VIII);

B. Empirical hints from affective neuroscience (Section I);

C. A priori hints from phenomenology;

D. Empirical hints from neurocomputational syntax;

E. The Non-adaptedness Principle;

F. Common patterns across physical formalisms (lessons from physics). None of these heuristics determine the answer, but in aggregate they dramatically reduce the search space.

IX.A: Structural distinctions in Qualia space (Section VIII):

In the previous section, we noted that the following distinctions about qualia can be made: Global vs local; Simple vs complex; Atomic vs composite; Intuitively important vs intuitively trivial. Valence plausibly corresponds to a global, simple, atomic, and intuitively important mathematical property.

[…]

Music is surprisingly pleasurable; auditory dissonance is surprisingly unpleasant. Clearly, music has many adaptive signaling & social bonding aspects (Storr 1992; Mcdermott and Hauser 2005)- yet if we subtract everything that could be considered signaling or social bonding (e.g., lyrics, performative aspects, social bonding & enjoyment), we’re still left with something very emotionally powerful. However, this pleasantness can vanish abruptly- and even reverse– if dissonance is added.

Much more could be said here, but a few of the more interesting data points are:

  1. Pleasurable music tends to involve elegant structure when represented geometrically (Tymoczko 2006);
  2. Non-human animals don’t seem to find human music pleasant (with some exceptions), but with knowledge of what pitch range and tempo their auditory systems are optimized to pay attention to, we’ve been able to adapt human music to get animals to prefer it over silence (Snowdon and Teie 2010).
  3. Results suggest that consonance is a primary factor in which sounds are pleasant vs unpleasant in 2- and 4-month-old infants (Trainor, Tsang, and Cheung 2002).
  4. Hearing two of our favorite songs at once doesn’t feel better than just one; instead, it feels significantly worse.

More generally, it feels like music is a particularly interesting case study by which to pick apart the information-theoretic aspects of valence, and it seems plausible that evolution may have piggybacked on some fundamental law of qualia to produce the human preference for music. This should be most obscured with genres of music which focus on lyrics, social proof & social cohesion (e.g., pop music), and performative aspects, and clearest with genres of music which avoid these things (e.g., certain genres of classical music).

[…]

X. A simple hypothesis about valence

To recap, the general heuristic from Section VIII was that valence may plausibly correspond to a simple, atomic, global, and intuitively important geometric property of a data structure isomorphic to phenomenology. The specific heuristics from Section IX surveyed hints from a priori phenomenology, hints from what we know of the brain’s computational syntax, introduced the Non-adaptedness Principle, and noted the unreasonable effectiveness of beautiful mathematics in physics to suggest that the specific geometric property corresponding to pleasure should be something that involves some sort of mathematically-interesting patterning, regularity, efficiency, elegance, and/or harmony.

We don’t have enough information to formally deduce which mathematical property these constraints indicate, yet in aggregate these constraints hugely reduce the search space, and also substantially point toward the following:

Given a mathematical object isomorphic to the qualia of a system, the mathematical property which corresponds to how pleasant it is to be that system is that object’s symmetry.

[…]

XI. Testing this hypothesis today

In a perfect world, we could plug many peoples’ real-world IIT-style datasets into a symmetry detection algorithm and see if this “Symmetry in the Topology of Phenomenology” (SiToP) theory of valence successfully predicted their self-reported valences.

Unfortunately, we’re a long way from having the theory and data to do that.

But if we make two fairly modest assumptions, I think we should be able to perform some reasonable, simple, and elegant tests on this hypothesis now. The two assumptions are:

  1. We can probably assume that symmetry/pleasure is a more-or-less fractal property: i.e., it’ll be evident on basically all locations and scales of our data structure, and so it should be obvious even with imperfect measurements. Likewise, symmetry in one part of the brain will imply symmetry elsewhere, so we may only need to measure it in a small section that need not be directly contributing to consciousness.
  2. We can probably assume that symmetry in connectome-level brain networks/activity will roughly imply symmetry in the mathematical-object-isomorphic-to-phenomenology (the symmetry that ‘matters’ for valence), and vice-versa. I.e., we need not worry too much about the exact ‘flavor’ of symmetry we’re measuring.

So- given these assumptions, I see three ways to test our hypothesis:

1. More pleasurable brain states should be more compressible (all else being equal).

Symmetry implies compressibility, and so if we can measure the compressibility of a brain state in some sort of broad-stroke fashion while controlling for degree of consciousness, this should be a fairly good proxy for how pleasant that brain state is.

2. Highly consonant/harmonious/symmetric patterns injected directly into the brain should feel dramatically better than similar but dissonant patterns.

Consonance in audio signals generally produces positive valence; dissonance (e.g., nails-on-a-chalkboard) reliably produces negative valence. This obviously follows from our hypothesis, but it’s also obviously true, so we can’t use it as a novel prediction. But if we take the general idea and apply it to unusual ways of ‘injecting’ a signal into the brain, we should be able to make predictions that are (1) novel, and (2) practically useful.

TMS is generally used to disrupt brain functions by oscillating a strong magnetic field over a specific region to make those neurons fire chaotically. But if we used it on a lower-powered, rhythmic setting to ‘inject’ a symmetric/consonant pattern directly into parts of the brain involved directly with consciousness, the result should produce good feeling- or at least, much better valence than a similar dissonant pattern.

Our specific prediction: direct, low-power, rhythmic stimulation (via TMS) of the thalamus at harmonic frequencies (e.g., @1hz+2hz+4hz+6hz+8hz+12hz+16hz+24hz+36hz+48hz+72hz+96hz+148hz) should feel significantly more pleasant than similar stimulation at dissonant frequencies (e.g., @1.01hz+2.01hz+3.98hz+6.02hz+7.99hz+12.03hz+16.01hz+24.02hz+35.97hz+48.05hz+72.04hz+95.94hz+ 147.93hz).

3. More consonant vagus nerve stimulation (VNS) should feel better than dissonant VNS.

The above harmonics-based TMS method would be a ‘pure’ test of the ‘Symmetry in the Topology of Phenomenology’ (SiToP) hypothesis. It may rely on developing custom hardware and is also well outside of my research budget.

However, a promising alternative method to test this is with consumer-grade vagus nerve stimulation (VNS) technology. Nervana Systems has an in-ear device which stimulates the Vagus nerve with rhythmic electrical pulses as it winds its way past the left ear canal. The stimulation is synchronized with either user-supplied music or ambient sound. This synchronization is done, according to the company, in order to mask any discomfort associated with the electrical stimulation. The company says their system works by “electronically signal[ing] the Vagus nerve which in turn stimulates the release of neurotransmitters in the brain that enhance mood.”

This explanation isn’t very satisfying, since it merely punts the question of why these neurotransmitters enhance mood, but their approach seems to work– and based on the symmetry/harmony hypothesis we can say at least something about why: effectively, they’ve somewhat accidentally built a synchronized bimodal approach (coordinated combination of music+VNS) for inducing harmony/symmetry in the brain. This is certainly not the only component of how this VNS system functions, since the parasympathetic nervous system is both complex and powerful by itself, but it could be an important component.

Based on our assumptions about what valence is, we can make a hierarchy of predictions:

  1. Harmonious music + synchronized VNS should feel the best;
  2. Harmonious music + placebo VNS (unsynchronized, simple pattern of stimulation) should feel less pleasant than (1);
  3. Harmonious music + non-synchronized VNS (stimulation that is synchronized to a different kind of music) should feel less pleasant than (1);
  4. Harmonious music + dissonant VNS (stimulation with a pattern which scores low on consonance measures such as (Chon 2008) should feel worse than (2) and (3));
  5. Dissonant auditory noise + non-synchronized, dissonant VNS should feel pretty awful.

We can also predict that if a bimodal approach for inducing harmony/symmetry in the brain is better than a single modality, a trimodal or quadrimodal approach may be even more effective. E.g., we should consider testing the addition of synchronized rhythmic tactile stimulation and symmetry-centric music visualizations. A key question here is whether adding stimulation modalities would lead to diminishing or synergistic/accelerating returns.

Raising the Table Stakes for Successful Theories of Consciousness

What should we expect out of a theory of consciousness?

For a scientific theory of consciousness to have even the slightest chance at being correct it must be able to address- at the very least– the following four questions*:

  1. Why consciousness exists at all (i.e. “the hard problem“; why we are not p-zombies)
  2. How it is possible to experience multiple pieces of information at once in a unitary moment of experience (i.e. the phenomenal binding problem; the boundary problem)
  3. How consciousness exerts the causal power necessary to be recruited by natural selection and allow us to discuss its existence (i.e. the problem of causal impotence vs. causal overdetermination)
  4. How and why consciousness has its countless textures (e.g. phenomenal color, smell, emotions, etc.) and the interdependencies of their different values (i.e. the palette problem)

In addition the theory must be able to generate experimentally testable predictions. In Popper’s sense the theory must make “risky” predictions. In a Bayesian sense the theory must be able to generate predictions that have a much higher likelihood given that the theory is correct versus not so that the a posteriori probabilities of the different hypotheses are substantially different from their priors once the experiment is actually carried out.

As discussed in a previous article most contemporary philosophies of mind are unable to address one or more of these four problems (or simply fail to make any interesting predictions). David Pearce’s non-materialist physicalist idealism (not the schizophrenic word-salad that may seem at first) is one of the few theories that promises to meet this criteria and makes empirical predictions. This theory addresses the above questions in the following way:

(1) Why does consciousness exist?

Consciousness exists because reality is made of qualia. In particular, one might say that physics is implicitly the science that studies the flux of qualia. This would imply that in fact all that exists is a set of experiences whose interrelationships are encoded in the Universal Wavefunction of Quantum Field Theory. Thus we are collapsing two questions (“why does consciousness arise in our universe?” and “why does the universe exist?”) into a single question (“why does anything exist?”). More so, the question “why does anything exist?” may ultimately be solved with Zero Ontology. In other words, all that exists is implied by the universe having literally no information whatsoever. All (apparent) information is local; universally we live in an information-less quantum Library of Babel.

(2) Why and how is consciousness unitary?

Due to the expansion of the universe the universal wavefunction has topological bifurcations that effectively create locally connected networks of quantum entanglement that are unconnected to the rest of reality. These networks meet the criteria of being ontologically unitary while having the potential to hold multiple pieces of information at once. In other words, Pearce’s theory of consciousness postulates that the world is made of a large number of experiences, though the vast majority of them are incredibly tiny and short-lived. The overwhelming bulk of reality is made of decohered micro-experiences which are responsible for most of the phenomena we see in the macroscopic world ranging from solidity to Newton’s laws of motion.

A few of these networks of entanglement are us: you, right now, as a unitary “thin subject” of experience, according to this theory, are one of these networks (cf. Mereological Nihilism). Counter-intuitively, while a mountain is in some sense much bigger than yourself, at a deeper level you are bigger than the biggest object you will find in a mountain. Taking seriously the phenomenal binding problem we have to conclude that a mountain is for the most part just made of fields of decohered qualia, and thus, unlike a given biologically-generated experience, it is not “a unitary subject of experience”. In order to grasp this point it is necessary to contemplate a very extreme generalization of Empty Individualism: not only is it that every moment of a person’s experience is a different subject of experience, but the principle applies to every single network of entanglement in the entire multiverse. Only a tiny minority of these have anything to do with minds representing worlds. And even those that participate in the creation of a unitary experience exist within an ecosystem that gives rise to an evolutionary process in which quintillions of slightly different entanglement networks compete in order to survive in the extreme environments provided by nervous systems. Your particular experience is an entanglement network that evolved in order to survive in the specific brain state that is present right now. In other words, macroscopic experiences are the result of harnessing the computational power of Quantum Darwinism by applying it to a very particular configuration of the CNS. Brain states themselves encode Constraint Satisfaction Problems with the networks of electric gradients across firing neurons in sub-millisecond scales instantiating constraints whose solutions are found with sub-femtosecond quantum darwinism.

(3) How can consciousness be causally efficacious?

Consciousness exerts its causal power by virtue of being the only thing that exists. If anything is causal at all, it must, in the final analysis, be consciousness. No matter one’s ultimate theory of causality, assuming that physics describes the flux of qualia, then what instantiates such causality has to be this very flux.

Even under Eternalism/block view of the universe/Post-Everettian QM you can still meaningfully reconstruct causality in terms of the empirical rules for statistical independence across certain dimensions of fundamental reality. The dimensions that have time-like patterns of statistical independence will subjectively be perceived as being the arrows of time in the multiverse (cf. Timeless Causality).

Now an important caveat with this view of the relationship between qualia and causality is that it seems as if at least a weak version of epiphenomenalism must be true. The inverted spectrum thought experiment (ironically usually used in favor of the existence of qualia) can be used to question the causal power of qualia. This brings us to the fourth point:

(4) How do we explain the countless textures of consciousness?

How and why does consciousness have its countless textures and what determines its interrelationships? Pearce anticipates that someday we will have a Rosetta Stone for translating patterns of entanglement in quantum fields to corresponding varieties of qualia (e.g. colors, smells, sounds, etc.). Now, admittedly it seems far fetched that the different quantum fields and their interplay will turn out to be the source of the different qualia varieties. But is there something that in principle precludes this ontological correspondence? Yes, there are tremendous philosophical challenges here, the most salient of which might be the “being/form boundary”. This is the puzzle concerning why states of being (i.e. networks of entangled qualia) would act a certain way by virtue of their phenomenal character in and of itself (assuming its phenomenal character is what gives them reality to begin with). Indeed, what could possibly attach at a fundamental level the behavior of a given being and its intrinsic subjective texture? A compromise between full-fledged epiphenomenalism and qualia-based causality is to postulate a universal principle concerning the preference for full-spectrum states over highly differentiated ones. Consider for example how negative and positive electric charge “seek to cancel each other out”. Likewise, the Quantum Chromodynamics of quarks inside protons and neutrons works under a similar but generalized principle: color charges seek to cancel/complement each other out and become “white” or “colorless”. This principle would suggest that the causal power of specific qualia values comes from the gradient ascent towards more full-spectrum-like states rather than from the specific qualia values on their own.  If this were to be true, one may legitimately wonder whether hedonium and full-spectrum states are perhaps one and the same thing (cf. Valence structuralism). In some way this account of the “being/form boundary” is similar to process philosophy,  but unlike process philosophy, here we are also taking mereological nihilism and wavefuction monism seriously.

However far-fetched it may be to postulate intrinsic causal properties for qualia values, if the ontological unity of science is to survive, there might be no other option. As we’ve seen, simple “patterns of computation” or “information processing” cannot be the source of qualia, since nothing that isn’t a quantum coherent wavefunction actually has independent existence. Unitary minds cannot supervene on decohered quantum fields. Thus the various kinds of qualia have to be searched for in networks of quantum entanglement; within a physicalist paradigm there is nowhere else for them to be.

Alternative Theories

I am very open to the possibility that other theories of consciousness are able to address these four questions. I have yet to see any evidence of this, though. But, please, change my mind if you can! Does your theory of consciousness rise to the challenge?


* This particular set of criteria was proposed by David Pearce (cf. Qualia Computing in Tucson). I would agree with him that these are crucial questions; indeed they make up the bare minimum that such a theory must satisfy. That said, we can formulate more comprehensive sets of problems to solve. An alternative framework that takes this a little further can be found in Michael Johnson’s book Principia Qualia (Eight Problems for a New Science of Consciousness).

Qualia Computing Attending the 2017 Psychedelic Science Conference

From the 19th to the 24th of April I will be hanging out at Psychedelic Science 2017 (if you are interested in attending but have not bought the tickets: remember you can register until the 14th of February).

12020058_10206806127125111_5414514709501746096_nIn case you enjoy Qualia Computing and you are planning on going, now you can meet the human who is mostly responsible for these articles. I am looking forward to meeting a lot of awesome researchers. If you see me and enjoy what I do, don’t be afraid to say hi.

Why Care About Psychedelics?

Although the study of psychedelics and their effects is not a terminal value here in Qualia Computing, they are instrumental in achieving the main goals. The core philosophy of Qualia Computing is to (1) map out the state-space of possible experiences, (2) identify the computational properties of consciousness, and (3) reverse-engineer valence so as to find the way to stay positive without going insane.

Psychedelic experiences happen to be very informative and useful in making progress towards these three goals. The quality and magnitude of the consciousness alteration that they induce lends itself to exploring these questions. First, the state-space of humanly accessible experiences is greatly amplified once you add psychedelics into the mix. Second, the nature of these experiences is all but computationally dull (cf. alcohol and opioids). On the contrary, psychedelic experiences involve non-ordinary forms of qualia computing: the textures of consciousness interact in non-trivial ways, and it stands to reason that some combinations of these textures will be recruited in the future for more than aesthetic purposes. They will be used for computational purposes, too. And third, psychedelic states greatly amplify the range of valence (i.e. the maximum intensity of both pain and pleasure). They unlock the possibility of experiencing peak bliss as well as intense suffering. This strongly suggests that whatever underpins valence at the fundamental level, psychedelics are able to amplify it to a fantastic (and terrifying) extent. Thus, serious valence research will undoubtedly benefit from psychedelic science.

It is for this reason that psychedelics have been a major topic explored here since the beginning of this project. Here is a list of articles that directly deal with the subject:

List of Qualia Computing Psychedelic Articles

1) Psychophysics For Psychedelic Research: Textures

How do you make a psychophysical experiment that tells you something foundational about the information-processing properties of psychedelic perception? I proposed to use an experimental approach invented by Benjamin J. Balas based on the anatomically-inspired texture analysis and synthesis techniques developed by Eero Simoncelli. In brief, one seeks to determine which summary statistics are sufficient to create perceptual (textural) metamers. In turn, in the context of psychedelic research, this can help us determine which statistical properties are best discriminated while sober and which differences are amplified while on psychedelics.

2) State-Space of Drug Effects

I distributed a survey in which I asked people to rate drug experiences along 60 different dimensions. I then conducted factor analysis on these responses. This way I empirically derived six major latent traits that account more than half of the variance across all drug experiences. Three of these factors are tightly related to valence, which suggests that hedonic-recalibration might benefit from a multi-faceted approach.

3) How to Secretly Communicate with People on LSD

I suggest that control interruption (i.e. the failure of feedback inhibition during psychedelic states) can be employed to transmit information in a secure way to people who are in other states of consciousness. A possible application of this technology might be: You and your friends at Burning Man want to send a secret message to every psychedelic user on a particular camp in such a way that no infiltrated cop is able to decode it. To do so you could instantiate the techniques outlined in this article on a large LED display.

4) The Hyperbolic Geometry of DMT Experiences: Symmetries, Sheets, and Saddled Scenes

This article discusses the phenomenology of DMT states from the point of view of differential geometry. In particular, an argument is provided in favor of the view that high grade psychedelia usually involves a sort of geometric hyperbolization of phenomenal space.

5) LSD and Quantum Measurements: Can you see Schrödinger’s cat both dead and alive on acid?

We provide an empirical method to test the (extremely) wild hypothesis that it is possible to experience “multiple branches of the multiverse at once” on high doses of psychedelics. The point is not to promote a particular interpretation of such experiences. Rather, the points is that we can actually generate predictions from such interpretations and then go ahead and test them.

6) Algorithmic Reduction of Psychedelic States

People report a zoo of psychedelic effects. However, as in most things in life, there may be a relatively small number of basic effects that, when combined, can account for the wide variety of phenomena we actually observe. Algorithmic reductions are proposed as a conceptual framework for analyzing psychedelic experiences. Four candidate main effects are proposed.

7) Peaceful Qualia: The Manhattan Project of Consciousness

Imagine that there was a world-wide effort to identify the varieties of qualia that promote joy and prosocial behavior at the same time. Could these be used to guarantee world peace? By giving people free access to the most valuable and prosocial states of consciousness one may end up averting large-scale conflict in a sustainable way. This articles explores how this investigation might be carried out and proposes organizational principles for such a large-scale research project.

8) Getting closer to digital LSD

Why are the Google Deep Dream pictures so trippy? This is not just a coincidence. People call them trippy for a reason.

9) Generalized Wada-Test

In a Wada-test a surgeon puts half of your brain to sleep and evaluates the cognitive skills of your awake half. Then the process is repeated in mirror image. Can we generalize this procedure? Imagine that instead of just putting a hemisphere to sleep we gave it psychedelics. What would it feel like to be tripping, but only with your right hemisphere? Even more generally: envision a scheme in which one alternates a large number of paired states of consciousness and study their mixtures empirically. This way it may be possible to construct a network of “opinions that states of consciousness have about each other”. Could this help us figure out whether there is a universal scale for subjective value (i.e. valence)?

10) Psychedelic Perception of Visual Textures

In this article I discuss some problems with verbal accounts of psychedelic visuals, and I invite readers to look at some textures (provided in the article) and try to describe them while high on LSD, 2C-B, DMT, etc. You can read some of the hilarious comments already left in there.

11) The Super-Shulgin Academy: A Singularity I Can Believe In

Hard to summarize.

 

The Binding Problem

[Our] subjective conscious experience exhibits a unitary and integrated nature that seems fundamentally at odds with the fragmented architecture identified neurophysiologically, an issue which has come to be known as the binding problem. For the objects of perception appear to us not as an assembly of independent features, as might be suggested by a feature based representation, but as an integrated whole, with every component feature appearing in experience in the proper spatial relation to every other feature. This binding occurs across the visual modalities of color, motion, form, and stereoscopic depth, and a similar integration also occurs across the perceptual modalities of vision, hearing, and touch. The question is what kind of neurophysiological explanation could possibly offer a satisfactory account of the phenomenon of binding in perception?
One solution is to propose explicit binding connections, i.e. neurons connected across visual or sensory modalities, whose state of activation encodes the fact that the areas that they connect are currently bound in subjective experience. However this solution merely compounds the problem, for it represents two distinct entities as bound together by adding a third distinct entity. It is a declarative solution, i.e. the binding between elements is supposedly achieved by attaching a label to them that declares that those elements are now bound, instead of actually binding them in some meaningful way.
Von der Malsburg proposes that perceptual binding between cortical neurons is signalled by way of synchronous spiking, the temporal correlation hypothesis (von der Malsburg & Schneider 1986). This concept has found considerable neurophysiological support (Eckhorn et al. 1988, Engel et al. 1990, 1991a, 1991b, Gray et al. 1989, 1990, 1992, Gray & Singer 1989, Stryker 1989). However although these findings are suggestive of some significant computational function in the brain, the temporal correlation hypothesis as proposed, is little different from the binding label solution, the only difference being that the label is defined by a new channel of communication, i.e. by way of synchrony. In information theoretic terms, this is no different than saying that connected neurons posses two separate channels of communication, one to transmit feature detection, and the other to transmit binding information. The fact that one of these channels uses a synchrony code instead of a rate code sheds no light on the essence of the binding problem. Furthermore, as Shadlen & Movshon (1999) observe, the temporal binding hypothesis is not a theory about how binding is computed, but only how binding is signaled, a solution that leaves the most difficult aspect of the problem unresolved.
I propose that the only meaningful solution to the binding problem must involve a real binding, as implied by the metaphorical name. A glue that is supposed to bind two objects together would be most unsatisfactory if it merely labeled the objects as bound. The significant function of glue is to ensure that a force applied to one of the bound objects will automatically act on the other one also, to ensure that the bound objects move together through the world even when one, or both of them are being acted on by forces. In the context of visual perception, this suggests that the perceptual information represented in cortical maps must be coupled to each other with bi-directional functional connections in such a way that perceptual relations detected in one map due to one visual modality will have an immediate effect on the other maps that encode other visual modalities. The one-directional axonal transmission inherent in the concept of the neuron doctrine appears inconsistent with the immediate bi-directional relation required for perceptual binding. Even the feedback pathways between cortical areas are problematic for this function due to the time delay inherent in the concept of spike train integration across the chemical synapse, which would seem to limit the reciprocal coupling between cortical areas to those within a small number of synaptic connections. The time delays across the chemical synapse would seem to preclude the kind of integration apparent in the binding of perception and consciousness across all sensory modalities, which suggests that the entire cortex is functionally coupled to act as a single integrated unit.

The Hyperbolic Geometry of DMT Experiences: Symmetries, Sheets, and Saddled Scenes

The Geometry of DMT States

This is an essay on the phenomenology of DMT. The analysis here presented predominantly uses algorithmic, geometric and information-theoretic frameworks, which distinguishes it from purely phenomenological, symbolic, neuroscientific or spiritual accounts. We do not claim to know what ultimately implements the effects here described (i.e. in light of the substrate problem of consciousness), but the analysis does not need to go there in order to have explanatory power. We posit that one can account for a wide array of (apparently diverse) phenomena present on DMT-induced states of consciousness by describing the overall changes in the geometry of one’s spationtemporal representations (what we will call “world-sheets” i.e. 3D + time surfaces; 3D1T for short). The concrete hypothesis is that the network of subjective measurements of distances we experience on DMT (coming from the relationships between the phenomenal objects one experiences in that state) has an overall geometry that can accurately be described as hyperbolic (or hyperbolic-like). In other words, our inner 3D1T world grows larger than is possible to fit in an experiential field with 3D Euclidean phenomenal space (i.e. an experience of dimension R2.5 representing an R3 scene). This results in phenomenal spaces, surfaces, and objects acquiring a mean negative curvature. Of note is that even though DMT produces this effect in the most consistent and intense way, the effect is also present in states of consciousness induced by tryptamines and to a lesser extent in those induced by all other psychedelics.

Conceptual Framework: Algorithmic Reduction

We will use the reduction framework originally proposed in the article Algorithmic Reductions of Psychedelic States. This means that we will be examining how algorithms and processes (as experienced by a subject of experience) can explain the dynamics of people’s phenomenology in DMT states. We do not claim “the substrate of consciousness” is becoming hyperbolic in any literal sense (though we do not discard that possibility). Rather, we interpret the hyperbolic curvature that experience acquires while on DMT as an emergent effect of a series of more general mechanism of action that can work together to change the geometry of a mind. These same mechanisms of action govern the dynamics of other psychedelic experiences; it is the proportion and intensity of the various “basic” effects that lead to the different outcomes observed. In other words, the hyperbolization of phenomenal space may not be a fundamental effect of DMT, but rather, it may be an emergent effect of more simple effects combined (not unlike how our seemingly smooth macroscopic space-time emerges from the jittery yet fundamental interactions that happen in a microscopic high-dimensional quantum foam).

In particular, we will discuss three candidate models for a more fundamental algorithmic reduction: (1) the synergistic effect of control interruption and symmetry detection resulting in a change of the metric of phenomenal space (analogously to how one can measure the geometry of hyperbolic graph embeddings), (2) the mind as a dynamic system with energy sources, sinks and invariants, in which curvature stores potential energy, and (3) a change in the underlying curvature of the micro-structure of consciousness. These models are not mutually-exclusive, and they may turn out to be compatible. More on this later.

What is Hyperbolic Geometry?

Perhaps the clearest way to describe hyperbolic space is to show examples of it:

The picture to the left shows a representation of a “saddle” surface. In geometry, saddle surfaces are 2-dimensional hyperbolic spaces (also called “hyperbolic planes” or H2). For a surface to have “constant curvature” it must look the same at every point. In other words, for a saddle to be a geometric saddle, every point in it must be a “saddle point” (i.e. a point with negative curvature). As you can see, saddles have the property that the angles of a triangle found in them add up to less than 180 degrees (compare that to surfaces with positive curvature such as the 2-sphere, in which the angles of a triangle add up to more than 180 degrees). Generalizing this to higher dimensions, the middle image above shows a cube in H3 (i.e. a hyperbolic space of three dimensions). This cube, since it is in hyperbolic space, has thin edges and pointy corners. More generally, the corners of a polyhedra (and polytopes) will be more pointy in Hn than they are in Rn. This is why you can see in the right image a dodecahedron with right-angled corners, which in this case can tile H3 (cf. Not Knot). Such a thing- people of the past might say- is an insult to the imagination. Times are changing, though, and hyperbolic geometry is now an acceptable subject of conversation.

An important property of hyperbolic spaces is the way in which the area of a circle (or the n-dimensional volume of a hypersphere) increases as a function of its radius. In 2D Euclidean space the area grows quadratically with the radius. But on H2, the area grows exponentially as a function of the radius! As you may imagine, it is easy to get lost in hyperbolic space. A few steps take you to an entirely different scene. More so, your influence over the environment is greatly diminished as a function of distance. For example, the habitable region of solar systems in hyperbolic spaces (i.e.the Goldilocks zone) is extremelly thin. In order to avoid getting burned or freezing to death you would have to place your planet within a very narrow distance range from the center star. Most of what you do in hyperbolic space either stays as local news or is quickly dissipated in an ever-expanding environment.

We Can Only Remember What We Can Reconstruct

We cannot experience H2 or H3 manifolds under normal circumstances, but we can at least represent some aspects of them through partial embeddings (i.e. instantiations as subsets of other spaces preserving properties) and projections into more familiar geometries. It is important to note that such representations will necessarily be flawed. As it turns out, it is notoriously hard to truly embed H2 in Euclidean 3D space, since doing so will necessarily distort some properties of the original H2 space (such as distance, angle, area, local curvature, etc.). As we will discuss further below, this difficulty turns out to be crucial for understanding why DMT experiences are so hard to remember. In order to remember the experience you need to create a faithful and memorable 3D Euclidean embedding of it. Thus, if one happens to experience a hyperbolic object and wants to remember as much of it as possible, one will have to think strategically about how to fold, crunch and deform such object so that it can be fit in compact Euclidean representations.

What about DMT suggests hyperbolic geometry?

Why should we believe that phenomenal space on DMT (and to a lesser extent on other psychedelics) becomes hyperbolic-like?  We will argue that the features people use to describe their trips as well as concrete mathematical observations of such features point directly to hyperbolic geometry. Here is a list of such features (arranged from least to most suggestive… you know, for dramatic effect):

  1. Perception of far-out travel (as we said, small movements in hyperbolic space lead to huge changes in the scene).
  2. Feelings of becoming big (you can fit a lot more inside a circle of radius r in hyperbolic space).
  3. The space experienced is often depicted as “more real and more dense than normal”.
  4. The use of terms like “mind-expanding” and “warping” to describe the effects of the drug are very common.
  5. People describing it as “a different kind of space” and frequently using the word “hyperspace” to talk about it.
  6. Difficulty integrating/remembering the objects and scenes experienced (e.g. “they were too alien to recall”).
  7. Constant movement/acceleration and change of perspectives which are often described as “unfolding scenes and expanding patterns” (cf. the chrysanthemum, jitterbox).
  8. Continuous change of the scene’s context through escape routes: A door that leads to a labyrinth that leads to branching underground tunnels that lead to mirror rooms that lead to endless windows, and the one you take leading you to a temple with thirty seven gates which lead you to a kale salad world etc. (example).
  9. Crowding of scene beyond the limits of Euclidean space (users frequently wondering “How was I able to fit so much in my mind? I don’t see any space for my experience to fit in here!”)
  10. Reported similarity with fractals.
  11. Omnipresence of saddles making up the structural constraints of the hallucinated scenes. For example, one often hears about experiencing scenes saturated with: joints, twists, bifurcations, curved alleys, knots, and double helixes.
  12. Looking at self-similar objects (such as cauliflowers) can get you lost in what seems like endless space. (Note: beware of the potential side effects of looking at a cauliflower on DMT*).
  13. PSIS-like experiences where people seem to experience multiple alternative outcomes from each event at the same time (this may be the result of “hyperbolic branching” through time rather than space).
  14. Psychedelic replication pictures usually include features that can be interpreted as hyperbolic objects embedded in Euclidean 3D.
  15. People describe “incredibly advanced mechanisms” and “impossible objects” that cannot be represented in our usual reality (e.g. Terence Mckenna’s self-dribbling basketballs).
  16. At least one mathematician has stated that what one experiences on DMT cannot be translated into Euclidian geometry (unlike what one experiences on LSD).
  17. We received a series of systematic DMT trip-reports by a math enthusiast and experienced psychonaut who claims that the surfaces experienced on DMT are typically composed of hyperbolic tilings (which imply a negative curvature; cf. wallpaper groups).

This article goes beyond claiming a mere connection between DMT and hyperbolic geometry. We will be more specific by addressing the aspects of the experience that can be interpreted geometrically. To do so, let us now turn to a phenomenological description of the way DMT experiences usually unfold:

The Phenomenology of DMT experiences: The 6 Levels

In order to proceed we will give an account of a typical vaporized DMT experience. You can think of the following six sections as stages or levels of a DMT journey. Let me explain. The highest level you get to depends on the dose consumed, and in high doses one experiences all of the levels, one at a time, and in quick succession (i.e. on high doses these levels are perceived as the stages of the experience). If one takes just enough DMT to cross over to the highest level one reaches during the journey for only a brief moment, then that level will probably be described as “the peak of the experience”. If, on the other hand, one takes a dose that squarely falls within the milligram range for producing a given level, it will be felt as more of a “plateau”. Each level is sufficiently distinct from the others that people will rarely miss the transitions between them.

The six levels of a DMT experience are: Threshold, Chrysanthemum, Magic Eye, Waiting Room, Breakthrough, and Amnesia. Let us dive in!

(Note: The following description assumes that the self-experimenter is in good physical and mental health at the time of consuming the DMT. It is well known that negative states of consciousness can lead to incomprehensible hellscapes when “boosted” by DMT (please avoid DMT at all costs while you are drunk, depressed, angry, suicidal, irritable, etc.). The full geometry is best appreciated on a mentally and emotionally balanced set and settings.)

(1) Threshold

The very first alert of something unusual happening may take between 3 to 30 seconds after inhaling the DMT, depending on the dose consumed. Rather than a clear sensorial or cognitive change, the very first hint is a change in the apparent ambiance of one’s setting. You know how at times when you enter a temple, an art museum, a crowd of people, or even just a well decorated restaurant you can abstract an undefinable yet clearly present “vibe of the place”? There’s nothing overt or specific about it. The ambiance of a place is more of an overall gestalt than a localized feeling. An ambiance somehow encodes information about the social, ideological and aesthetic quality of the place or community you just crashed into, and it tells you at a glance which moods are socially acceptable and which ones are discouraged. The specific DMT vibe you feel on a given session can be one of a million different flavors. That said, whether you feel like you entered a circus or joined a religious ceremony, the very first hint of a DMT experience is nonetheless always (or almost always) accompanied with an overall feeling of significance. The feeling that something important is about to happen or is happening is made manifest by the vibe of the state. This vibe is usually present for at least the first 150 seconds or so of the journey. Interestingly, the change in ambiance is shorter-lived than the trip itself; it seems to go away before the visuals vanish quickly declining once the the peak is over.

Within seconds after the change in ambiance, one feels a sudden sharpening of all the senses. Some people describe this as “upgrading one’s experience to an HD version of it”. The level of detail in one’s experience is increased, yet the overall semantic content is still fairly intact. People say things like: “Reality around me seems more crisp” and “it’s like I’m really grasping my surroundings, you know? fully in tune with the smallest textures of the things around me.” Terence Mckenna described this state as follows: “The air appears to suddenly have been sucked out of the room because all the colors brighten visibly, as though some intervening medium has been removed.”

SONY DSC

On a schedule of repeated small doses (below 4 mg; preferably i.m.) one can stabilize this sharpening of the senses for arbitrarily long periods of time. I am a firm believer that this state (quite apart from the alien experiences on higher doses) can already be recruited for a variety of computational and aesthetic tasks that humans do in this day and age. In particular, the state itself seems to enable grasping complex ideas with many parameters without distorting them, which may be useful for learning mathematics at an accelerated pace. Likewise, the sate increases one’s awareness of one’s surroundings (possibly at the expense of consuming many calories). I find it hard to imagine that artists will not be able to use this state for anything valuable.

(2) The Chrysanthemum

If one ups the dose a little bit and lands somewhere in the range between 4 to 8 mg, one is likely to experience what Terrence McKenna called “the Chrysanthemum”. This usually manifests as a surface saturated with a sort of textured fabric composed of intricate symmetrical relationships, bright colors, shifting edges and shimmering pulsing superposition patterns of harmonic linear waves of many different frequencies.

Depending on the dose consumed one may experience either one or several semi-parallel channels. Whereas a threshold dose usually presents you with a single strong vibe (or ambiance), the Chrysanthemum level often has several competing vibes each bidding for your attention. Here are some examples of what the visual component of this state of consciousness may look like.

The visual component of the Chrysanthemum is often described as “the best screen saver ever“, and if you happen to experience it in a good mood you will almost certainly agree with that description, as it is usually extremelly harmonious, symmetric and beautiful in uncountable ways. No external input can possibly replicate the information density and intricate symmetry of this state; such state has to be endogenously generated as a a sort of harmonic attractor of your brain dynamics.

You can find many replications of Chrysanthemum-level DMT experiences on the internet, and I encourage you to examine their implicit symmetries (this replication is one of my all-times favorite).

In Algorithmic Reduction of Psychedelic States we posited that any one of the 17 wallpaper symmetry groups can be instantiated as the symmetries that govern psychedelic visuals. Unfortunately, unlike the generally slow evolution of usual psychedelic visuals, DMT’s vibrational frequency forces such visuals to evolve at a speed that makes it difficult for most people to spot the implicit symmetry elements that give rise to the overall mathematical structure underneath one’s experience. For this reason it has been difficult to verify that all 17 wallpaper groups are possible in DMT states. Fortunately we were recently able to confirm that this is in fact the case thanks to someone who trained himself to do just this. I.e. detecting symmetry elements in patterns at an outstanding speed.

An anonymous psychonaut (whom we will call researcher A) sent a series of trip report to Qualia Computing detailing the mathematical properties of psychedelic visuals under various substances and dose regimens. A is an experienced psychonaut and a math enthusiast who recently trained himself to recognize (and name) the mathematical properties of symmetrical patterns (such as in works of art or biological organisms). In particular, he has become fluent at naming the symmetries exhibited by psychedelic visuals. In the context of 2D visuals on surfaces, A confirms that the symmetrical textures that arise in psychedelic states can exhibit any one of the 17 wallpaper symmetry groups. Likewise, he has been able to confirm that every possible spherical symmetry group can also be instantiated in one’s mind on these states.

The images below show some examples of the visuals that A has experienced on 2C-B, LSD, 4-HO-MET and DMT (sources: top left, top middle, the rest were made with this service):

The Chrysanthemum level interacts with sensory input in an interesting way: the texture of anything one looks at quickly becomes saturated with nested 2-dimensional symmetry groups. If you took enough DMT to take you to this level and you keep your eyes open and look at a patterned surface (i.e. statistical texture), it will symmetrify beyond recognition. A explains that at this level DMT visuals share some qualities with those of, say, LSD, mescaline, and psilocin. Like other psychedelics, DMT’s Chrysanthemum level can instantiate any 2-dimensional symmetry, yet there are important differences from other psychedelics at this dose range. These include the consistent change in ambiance (already present in threshold doses), the complexity and consistency of the symmetrical relationships (much more dense and whole-experience-consistent than is usually possible with other psychedelics), and the speed (with a control-interruption frequency reaching up to 30 hertz, compared to 10-20 hertz for most psychedelics). Thus, people tend to point out that DMT visuals (at this level) are “faster, smaller, more detailed and more globally consistent” than on comparable levels of alteration from similar agents.

Now, if you take a dose that is a little higher (in the ballpark of 8 to 12 mg), the Chrysanthemum will start doing something new and interesting…

(3) The Magic Eye Level

A great way to understand the Magic Eye level of DMT effects is to think of the Chrysanthemum as the texture of an autostereogram (colloquially described as “Magic Eye” pictures). Our visual experience can be easily decomposed into two points-of-view (corresponding to the feed coming from each eye) that share information in order to solve the depth-map problem in vision. This is to map each visual qualia to a space with relative distances so (a) the input is explained and (b) you get recognizable every-day objects represented as implicit shapes beneath the depth-map. You can think of this process as a sort of hand-shake between bottom-up perception and top-down modeling.

In everyday conditions one solves the depth-map problem within a second of opening one’s eyes (minus minor details that are added as one looks around). But on DMT, the “low-level perceptions” looks like a breathing Chrysanthemum, which means that the top-down modeling has that “constantly shifting” stuff to play with. What to make of it? Anything you can think of.

There are three major components of variance on the DMT Magic Eye level:

  1. Texture (dependent on the Chrysanthemum’s evolution)
  2. World-sheet (non-occluduing 3D1T depth maps)
  3. Extremelly lowered information copying threshold.

The image on the left is a lobster, the one on the center is a cone and the one to the right contains furniture (a lamp, a chair and a table). Notice that what you see is a sort of depth-map which encodes shapes. We will call this depth-map together with the appearance of movement and acceleration represented in it, a world-sheet.

World-Sheets

The world-sheet encodes the “semantic content” of the scene and is capable of representing arbitrary situations (including information about what you are seeing, where you are, what the entities there are doing, what is happening, etc.).

It is common to experience scenes from usually mundane-looking places like ice-cream stores, play pens, household situations, furniture rooms, apparel, etc.. Likewise, one frequently sees entities in these places, but they rarely seem to mind you because their world is fairly self-contained. As if seeing through a window. People often report that the worlds they saw on a DMT trip were all “made of the same thing”. This can be interpreted as the texture becoming the surfaces of the world-sheet, so that the surfaces of the tables, chairs, ice-cream cones, the bodies of the people, and so on are all patterned with the same texture (just as in actual autostereograms). This texture is indeed the Chrysanthemum completely contorted to accommodate all the curvature of the scene.

Magic Eye level scenes often include 3D geometrical shapes like spheres, cones, cylinders, cubes, etc. The complexity of the scene is roughly dose-dependent. As one ups the highness (but still remaining within the Magic Eye level) complex translucid qualia crystals in three dimensions start to become a possibility.

Whatever phenomenal objects you experience on this level that lives for more than a millisecond needs to have effective strategies for surviving in an ecosystem of other objects adapted to that level. Given the extremelly lowered information copying threshold, whatever is good at making copies of itself will begin to tesselate, mutate and evolve, stealing as much of your attention as possible in the way. Cyclic transitions occupy one’s attention: objects quickly become scenes which quickly become gestalts from which a new texture evolves in which new objects are detected and so on ad infinitum.

katoite-hydrogarnet

A reports that at this dose range one can experience at least some of the 230 space groups as objects represented in the world-sheet. For example, A reports having stabilized a structure with a Pm-3m symmetry structure, not unlike the structure of ZIF-71-RHO. Visualizing such complex 3D symmetries, however, does seem to require previous training and high levels of mental concentration (i.e. in order to ensure that all the symmetry elements are indeed what they are supposed to be).

There is so much qualia laying around, though, at times not even your normal space can contain it all. Any regular or semi regular symmetrical structure you construct by focusing on it is prone to overflow if you focus too much on it. What does this mean? If you focus too much on, for example, the number 6, your mind might represent the various ways in which you can arrange six balls in a perfectly symmetrical way. Worlds made of hexagons and octahedrons interlocked in complex but symmetrical ways may begin to tesselate your experiential field. With every second you find more and more ways of representing the number six in interesting, satisfying, metaphorically-sound synesthetic ways (cf. Thinking in Numbers). Now, what happens if you try to represent the number seven in a symmetric way on the plane? Well, the problem is that you will have too many heptagons to fit in Euclidean space (cf. Too Many Triangles). Thus the resulting symmetrical patterns will seem to overflow the plane (which is often felt as a folding and fluid re-arrangement, and when there is no space left in a region it either expands space or it is felt as some sort of synesthetic tension or stress, like a sense of crackling under a lot of pressure).

In particular, A claims that in the lower ranges of the DMT Magic Eye level the texture of the Chrysanthemum tends to exhibit heptagonal and triheptagonal tilings (as shown in the picture above). A explains that at the critical point between the Chrysanthemum and the Magic Eye levels the intensity of the rate of symmetry detection of the Chrysanthemum cannot be contained to a 2D surface. Thus, the surface begins to fold, often in semi-symmetric ways. Every time one “recognizes” an object on this “folding Chrysanthemum” the extra curvature is passed on to this object. As the dose increases, one interprets more and more of this extra curvature and ends up shaping a complex and highly dynamic spatiotemporal depth map with hyperbolic folds. In the upper ranges of the Magic Eye level the world-sheet is so curved that the scenes one visualize are intricate and expansive, feeling at times like one is able to peer through one’s horizon in all directions and see oneself and one’s world from a distance. At some critical point one may feel like the space around one is folding into a huge dome where the walls are made of whatever texture + world-sheet combination happened to win the Darwinian selection pressures applied to the qualia patterns on the Magic Eye level. This concentrated hyperbolic synesthetic texture is what becomes the walls of the Waiting Room…

(4) Waiting Room

In the range of 12-25mg of DMT a likely final destination is the so-called Waiting Room. This experience is distinguished from the Magic Eye level in several ways: first, the world-sheet at this level breaks into several quasi-independent components, each evolving semi-autonomously. Second, one goes from “partial immersion” into “full immersion”. The transition between Magic Eye and Waiting Room often looks like “finding a very complex element in the scene and using it as a window into another dimension”. The total 2D surface curvature present (by adding up the curvature of all elements in the scene) is substantially higher than that of the Magic Eye level, and one can start to see actual 3D hyperbolic space. Perhaps a way of describing this transition is as follows: The curvature of the world-sheet gets to be so extreme that in order to accommodate it one’s entire multi-modal experiential field becomes involved, and a feeling of total and complete synchronization of all senses into a unified synesthetic experience is inescapable (often described as the “mmmMMMMMMM+++++!!!” whole-body tone people report). Thus the feeling of entering into an entirely new dimension. This explains what people mean when they say: “I experienced such an intense pressure that my soul could not be contained in my tiny body, and the intense pressure launched me into a bigger world”.

The images above, taken together, are meant as an impressionistic replication of what a Waiting Room experience may feel like. On the left you see the textured world-sheet curved in several ways resulting in an enclosed room with shimmering walls and an entity looking at a futuristic-looking contraption. The images on the right are meant to illustrate the ways in which the texture of the world-sheet evolves: you will find that the micro-structure of such texture is constantly unfolding in new symmetrical ways (bottom right), and propagating such changes throughout the entire surface at a striking speed (top right).

DMT Waiting Rooms contain entities that at times do interact directly with you. Their reality is perceived as a much more intense and intimate version of what human interaction normally is, but they do not give the impression of being telepathic. That said, their power is felt as if they could radiate it. One could say that this level of DMT places you in such an intimate, vulnerable and open state that interpreting the entities in a second-person social mode is almost inevitable. It is like interacting with someone you really know (or perhaps someone you really really want to know… or really really don’t want to know), except that the whole world is made of those feelings and some entities inhabit that world.

Serious hard-core psychonauts tend to describe the Wating Room as a temporary stopgap. Indeed more poetry could ever be written about the Waiting Room states of consciousness than about most human activities, for its state-space is larger, more diverse and more hedonically loaded. But even so, it is important to realize that there are even weirder states. Serious psychonauts exploring the upper ranges of humanly-accessible high energy consciousness research may see Waiting Rooms as a stepping stones to the real deal…

(5) Breakthrough

If one manages to ingest around 20-30mg of DMT there is a decent chance that one will achieve a DMT breakthrough experience (some sources place the dosage as high as 40mg). There is no agreed-upon definition for a “DMT breakthrough”, but most experienced users confirm that there is a qualitative change in the structure and feel of one’s experience on such high doses. Based on A’s observations we postulate that DMT breakthroughs are the result of a world-sheet with a curvature so extreme that topological bifurcations start to happen uncontrollably. In other words, the very topology of one’s world-sheet is forced to change in order to accommodate all of the intense curvature.

The geometry of space you experience may suddenly go from a simply-connected space into something else. What does this mean? Suddenly one may feel like space itself is twisting and reconnecting to itself in complex (and often confusing) ways. One may find that given any two points on this “alien world” there may be loops between them. This has drastic effects on one’s every representation (including, of course, the self-other divide). The particular feeling that comes with this may explain the presence of PSIS-like experiences induced by DMT and high dose LSD (cf. LSD and Quantum Measurements). Since the topological bifurcations are happening on a 3D1T world-sheet, this may look like “multiple things happening at once” or “objects taking multiple non-overlapping paths at once in order to get from one place into another”. The entities at this level feel transpersonal: due to the extreme curvature it is hard to distinguish between the information you ascribe to your self-model and the information you ascribe to others. Thus one is all over the place, in a literal topological sense.

While on the Waiting Room one can stabilize the context where the experience seems to be taking place, on a DMT breakthrough state one invariably “moves across vast regions, galaxies, universes, realities, etc.” in a constant uncontrollable way. Why is this? This may be related to whether one can contain the curvature of the objects one attends to. If the curvature is uncontrollable, it will “pass on to the walls” and result in constant “context switches”. In fact, such a large fraction of 3D space is perceived as hyperbolic in one way or another, that one seems to have access to vast regions of reality at the same time. Thus a sense of radical openness is often experienced.

(6) Amnesia Level

Unlike 5-MeO-DMT, “normal DMT” experiences are not typically so mind-warping that they dissolve one’s self-model completely. On the contrary, many people report DMT as having “surprisingly little effect on one’s sense of self except at very high doses” relative to the overall intensity of the alteration. Thus, DMT usually does not produce amnesia due to ego death directly. Rather, the amnesic properties of DMT at high doses can be blamed on the difficulty of instantiating the necessary geometry to make sense of what was experienced. In the case of doses above “breakthrough experiences” there is a chance that the user will not be able to recall anything about the most intense periods of the journey. Unfortunately, we are not likely to learn much from these states (that is, until we live in a community of people who can access other phenomenal geometries in a controlled fashion).

Recalling the Immemorial

We postulate that the difficulty people have remembering the phenomenal quality of a DMT experience is in part the result of not being able to access the geometry required to accurately relive their hallucinations. The few and far apart elements of the experience that people do somehow manage to remember, we posit, are those that happen to be (relatively) easy to embed in 3D Euclidean space. Thus, we predict that what people do manage to “bring back” from hyperspace will be biased towards those things that can be represented in R3.

This explains why people remember experiencing intensely saddled scenes (e.g. fractals, tunnels, kale worlds, recursive processes, and so on). Unfortunately most information-rich and interesting (irreducible, prime) phenomenal objects one experiences on DMT are by their very nature impossible to embed in our normal experiential geometry. This problem reveals an intrinsic limitation that comes from living in a community of intelligences (i.e. contemporary humans) who are constrained in the range of state-spaces of consciousness that they can access. This realization calls for a new epistemological paradigm, one that incorporate state-specific representations into a globally accessible database of states of consciousness, together with the network that emerges from their mutual (in)intelligibility.

DMT Objects

The increased curvature of one’s world-sheet can manifest in endless ways. In some important ways, the state-space of possible scenes that you can experience on DMT is much bigger than what you can experience on normal states of consciousness. Strictly speaking, you can represent more scenes on DMT states than in most other states because the overall amount qualia available is much larger. Of course the very dynamics of these experiences constrains what can be experienced, so there are still many things inaccessible on DMT. For instance, it may be impossible to experience a perfectly uniform blue screen (since the Chrysanthemum texture is saturated with edges, surfaces and symmetrical patterns). Likewise, scenes that are too irregular may be impossible to stabilize given the omnipresent symmetry enhancement found in the state.

What are the nature of the objects and entities one experiences on DMT? Magic Eye level experiences tend to include objects that are usually found in our everyday life. It is at the DMT waiting room level and above that the “truly impossible objects” begin to emerge. In particular, all of these objects are often curved in extreme ways. They condense within them complex networks of interlocking structures sustaining an overall superlative curvature. Here are some example objects that one can experience on Waiting Room and Breakthrough level experiences:

Notice that all of these images have many saddles everywhere. Ultimately, the range of objects one can experience on such states includes many other features that are impossible to represent in R3. The objects that people do manage to bring back and recall later on, are precisely those that can be embedded in R3. Thus you often see extremelly contorted wrapped-up objects. The most interesting ones (such as quasi-regular H3 tilings or irreducible objects) are next-to-impossible to bring back in any meaningful way, for now at least.

DMT Space Expansion

The expansion of space responsible for the increased curvature happens anywhere you direct your attention (including the objects you see). Here you can see what it may look like to stare at a DMT object: This is called the “jitterbox” mechanism.

DMT entities

DMT entities come in many forms, and their overall quality is extremelly dose-dependent. Rather than describing any specific manifestation we will instead briefly characterize the rough properties of the entities experienced based on the level reached.

  1. Threshold: Usually the ambiance change has a social feel to is. More similar to entering a room of people of an alien culture, than entering an empty cave or a warm pool on your own. In this sense the very beginning of a DMT experience may already frame the experience in social terms and facilitate the expectation of meeting entities.
  2. Chrysanthemum: One can feel perhaps the subtle presence of entities, but they are often interpreted as “feeling connected” to one’s friends, relatives and acquaintances. The feeling does not manifest in any clear spatial way, though. Other than that, this state is apersonal in the sense that one does not see any entity directly.
  3. Magic Eye: Here the entities can be roughly described as having an impersonal relationship with you. They are just there, hanging out on their own, often engrossed with whatever activities your world-sheet is capable of representing for them.
  4. Waiting Room: At this level entities start becoming able to interact with you. They feel like autonomous beings wrapped in mystery. Their intentions, what they know, and their emotional states can be guessed from their behavior, but they are not immediatly obvious.
  5. Breakthrough: At this level the entities one meets seem to have what we might call a transpersonal relationship with you. They share their own internal states (emotions, knowledge, wishes, etc) with you. It feels like they can communicate telepathically and “see through” you. One cannot hide one’s “private” mental contents from them at this level.
  6. Amnesia: One cannot remember, of course, exactly what happens here. But if trip reports are any indication, this level is reminiscent of highly “mystical” states in which one’s implicit beliefs about Personal Identity are obliterated and replaced by the feeling of becoming an all-encompassing entity. “Union with God” and “Samadhi” are terms that describe the subjective feeling of self in this state. In other words, at this level it is impossible to distinguish between oneself and other entities, for all is represented as one. (Beware of never trying to go here if you feel bad at the time since negative hedonic tone can be amplified just as much as a good feeling such as Samadhi).

Modeling the Hyperbolic Geometry of DMT

How can we explain the drastic geometric changes of phenomenal space on DMT? As mentioned earlier, we will discuss three (non-mutually exclusive) hypothesis. These hypothesis work at the level of an algorithmic reduction, which means that we will go deeper than just describing information processing and phenomenology. We will stop short of addressing the implementation level of abstraction. It is worth pointing out that describing the ways in which DMT experiences are hyperbolic is in itself an algorithmic reduction. What we are about to do is to develop a more granular algorithmic reduction in which we try to explain why hyperbolic geometry emerges on DMT states by postulating underlying processes. Here are the three reductions:

(1) Control Interruption + Symmetry detection = Change in Metric

Recall that on a previous article we algorithmically reduced general psychedelic states. The building blocks of that reduction were:

  1. Control Interruption (which amounts to a “longer half-life for all qualia”)
  2. Drifting (“breathing walls, eyes moving from their normal place, waving sensations”)
  3. Enhanced Pattern Recognition (pareidolia, cf. Getting Closed to Digital LSD)
  4. Lowered Symmetry Detection Threshold (quasi-symmetric patterns tend to “lock into” perfectly symmetrical structures)

Using this framework one can argue that DMT makes space more hyperbolic in the following way: in high amounts the synergistic effect of control interruption together with extremelly lowered symmetry detection thresholds experienced in quick succession makes the subjective distance between the points in the phenomenal objects in the scene evolve a hyperbolic metric. How would this happen? The key thing to realize is that in this model the usual quasi-Euclidean space we experience is an emergent effect of an equilibrium between these two forces. Even in normal circumstances our world-sheet is continuously regenerated; the rate at which symmetrical relationships in the scene are detected is balanced by the rate at which these subjective measurements are forgotten. This usually results in an emergent Euclidean geometry. On DMT the rate of symmetry detection increases while the rate of “forgetting” (inhibiting control) decreases. Attention points out more relationships in quick succession and this creates a network of measured subjective distances that cannot be embedded in Euclidean 3D space. Thus there is an overflow of symmetries. We are currently working on a precise mathematical model of this process in order to reconstruct a hyperbolic metric out of these two parameters. In this model, control interruption is interpreted as a change in the decay for subjective measurements of distance in one’s mind, whereas the lowered symmetry detection threshold is interpreted as a change in the probability of measuring the distance between any two given points as a function of the network of distances already measured.

The curvature increase is most salient where there is already a lot of measurements made, since highly-measured regions focus attention and attention drives symmetry detection. Thus, focusing on any surface will make the surface itself hyperbolic (rather than the 3D space, since measurements are mostly concentrated on the surface). On the other hand, if the curvature is too high to keep on a 2D surface, it will “jump” to 3D or even 3D1T (i.e. branching out the temporal component of one’s experience). The result is that the total curvature of one’s 3D1T world-sheet increases on DMT in a dose-dependent way.

Different doses lead to different states of curvature homeostasis. Each part of the worldsheet has constantly-morphing shapes and sudden curvature changes, but the total curvature is nonetheless more or less preserved on a given dose. It is not easy to get rid of excess curvature. Rather, whenever one tries to reduce the curvature in one part of the scene one is simply pushing it elsewhere. Even when one manages to push most of the curvature out of a given modality (e.g. vision) it is likely to quickly return in another modality (e.g. kinesthetic or auditory landscape) since attention never ceases on a DMT trip. Such apparent dose-dependent global curving of the world-sheet (and its jump from one modality into another) constrains the shape of the objects one can represent on the state (thus leading to alien-looking highly-curved objects similar to the ones shown above).

(2) Dynamic System Account: Energy Sources, Sinks and Invariants

Energy Invariants

Let us define a notion of energy in consciousness so that we can formalize the way experiences warps and transforms on DMT. Assume that one needs “energy” in order to instantiate a given experience (really, this is just an implicit invariant and we could use a different name). Each feature of a given experience needs a certain amount of energy, which roughly corresponds to a weighted sum of the intensity and the information content of an experience. For instance, the brightness of a point of colored light in one’s visual field is energy-dependent. Likewise, the information content in a texture, the number of represented symmetrical relationships, the speed by which an object moves (plus its acceleration), and even the curvature of one’s geometry. All of these features require energy to be instantiated.

Under normal circumstances the brain has many clever and (evolutionarily) appropriate ways of modulating the amount of energy present in different modules of one’s mind. That is, we have many programs that work as energy switches for different mental activities depending on the context. When we think, we have allocated a certain amount of energy to finding a shape/thought-form that satisfies a number of constraints. When it shape-shifting that energy in various ways and finding a solution, we either allocate more energy to it or perhaps give up. However, on DMT the energy cannot be switched off, and it can only pass from one modality into another. In other words, whereas in normal circumstances one uses strategically one’s ability to give energy limits to different tasks, on DMT one simply has constant high energy globally no matter what.

More formally, this model of DMT action says that DMT modifies the structure of one’s mind so that (1) energy freely passes from one form into another, and (2) energy floods the entire system. Let’s talk about energy sources and sinks.

Energy Sources and Sinks

In this algorithmic reduction DMT increases the amount of consciousness in one’s mind by virtue of impairing our normal energy sinks while increasing the throughput of its energy sources. This may frequently manifests as phenomenal spaces becoming hyperbolic in the mathematical-geometric sense of increasing its negative curvature as such curvature is one manifestation of higher levels of energy. Energy sinks are still present and they struggle to capture as much of the energy as possible. In particular, one energy sink is “recognition” of objects on the world-sheet.

This model postulates that attention functions as an energy source, whereas pattern recognition functions as an energy sink.

The Hamiltonian of a World-sheet

The total energy in one’s consciousness increases on DMT, and there is a constant flow between different ways for this energy to take form. That said, one can analyze piecewise the various components of one’s experience, specially if the network of energy exchange clusters well. In particular, we can postulate that world-sheets are fairly self-contained. Relative to other parts of the environment the mind is simulating, the world-sheet itself has a very high within-cluster energy exchange and a relatively low cross-cluster energy exchange. One’s world-sheet is very fluid, and little deformations propagate almost linearly throughout it. In a given dose plateau, if you add up the acceleration, the velocity, the curvature, and so on of every point in the world-sheet you will come up with a number that remains fairly constant over time. Thus studying the Hamiltonian of a world-sheet (i.e. the state-space given by a constant level of energy) can be very informative in describing both the information content and the experiential intensity of DMT experiences.

You can deform a surface without changing its local curvature. (Source: Gauss’ “Remarkable Theorem” [seriously not my quotes]). Thus on a DMT trip plateau there is still a lot of room for transformations of the world-sheet into different shapes with similar curvature.

Under normal circumstances the curvature of one’s world-sheet is, as far as I can tell, arousal-dependent. Have you noticed how when you feel tired you are more likely to defocus your visual experience? You are tired late at night and you are trying to watch a movie, but bringing the scene in focus is too much of an effort so you defocus for a little bit (still listening to the dialogue). What did you do that for? In the framework here proposed, you did that to diminish the energy it takes you to sustain a curved world-sheet with a lot of information. Doing so may be aesthetically pleasing and rewarding when fully awake or excited, but when tired the returns on doing the focusing are not great given how much effort it needs and the fact that the dialogue is more essential for the plot anyway.

It takes effort and wakefulness to focus on a complex scene with many intricate details. (Reading and trying to comprehend this essay may itself require significant conscious energy expenditure). For this reason we might say that DMT is an exceedingly effective arouser of consciousness.

Bayesian Energy Sinks

One essential property of our minds is that our level of mental arousal decreases when we interpret our experience as “expected”. People who can enjoy their own minds do so, in part, by finding unexpected ways of understanding expected things. In the presence of new information that one cannot easily integrate, however, one’s level of energy is adjusted upwards so that we try out a variety of different models quickly and try to sort out a model that does make the new information expected (though perhaps integrating new assumptions or adding content in other ways). When we cannot manage to generate a mental model that works out a likely model of what we are experiencing we tend to remain in an over-active state.

This general principle applies to the world-sheet. One of the predominant ways in which a world-sheet reduces its energy (locally) is by morphing into something you can recognize or interpret. Thus the world-sheet in some way keeps on producing objects, at first familiar, but in higher energies the whole process can seem desperate or hopeless: one can only recognize things with a stretch of the imagination. Since humans in general lack much experience with hyperbolic geometry, we usually don’t manage to imagine objects that are symmetric on their own native geometry. But when we do, and we fill them up with resonant light-mind-energy, then BAM! New harmonics of consciousness! New varieties of bliss! Music of the angels! OMG! Laughter till infinity and more- shared across the galaxy- in a hyperbolic transpersonal delight! It’s like LSD and N2O! Wow!

Forgive me, it is my first day. Let’s carry on. As one does not know any object that the world-sheet can reasonably be able to generate in high doses, and the world-sheet has so much energy on its own, energy can seem to spiral out of control. This explains in part the non-linear relationship between experienced intensity and DMT dose.

Like all aspects of one’s consciousness, the negative curvature of phenomenal space tends to decay over time (possibly through inhibition by the cortex). In this case, the feeling is one of “smoothing out the curves” and embedding the phenomenal objects in 3D euclidean space. However, this is opposed by the effect that attention and (degrees of) awareness have on our phenomenal sheet, which is to increase its negative curvature. On DMT, anything that attention focuses on will begin branching, copying itself and multiplying, a process that quickly saturates the scene to the point of filling more spatial relationships than would fit in Euclidean 3D. The rate at which this happens is dose-dependent. The higher the dose, the less inhibiting control there is and the more intense the “folding” property of attention will be. Thus, for different dosages one reaches different homeostatic levels of overall curvature in one’s phenomenal space. Since attention does not stop at any point during a DMT trip (it keeps being bright and intense all throughout) there isn’t really any rest period to sit back and see the curvature get smoothed out on its own. Everything one thinks about, perceives or imagines branches out and bifurcate at a high speed.

Every moment during the experience is very hard to “grasp” because the way one normally does that in usual circumstances is by focusing attention on it and shaping one’s world-sheet to account for the input. But here that very attention makes the world-sheet wobble, warp and expand beyond recognition. Thus one might say that during a solid DMT experience one never sees the same thing twice, as the experience continues to evolve. That is, of course, as long as you do not stumble upon (or deliberatively create) stable phenomenal objects whose structure can survive the warping effect of attention.

(3) Hyperbolic Micro-structure of Consciousness

Subjectively, A says, negative curvature is associated with more energy. Perhaps this curvature happens at a very low level? An example to light up the imagination is using heat to fold a sheet of metal (thanks to thermal expansion). Whatever your attention focuses on seems to get heated up (in some sense) and expand as a result. The folding patterns themselves seem to store potential energy. Left on their own, this extra energy stored as negative curvature usually dissipates, but on DMT this process is lowered (while the effect of increasing the energy is heightened). Could this be the result of some very very fine-level micro-experiential change that gradually propagates upwards? With the help of our normal mental processes the change in the micro-structure may propagate all the way into seemingly hyperbolic 2D and 3D surfaces.

Perhaps the most important difference between DMT in high doses and other psychedelics is that the micro-structure of consciousness drifts in such a way that tiny Droste effects bubble up into large Möbius transforms.

As noted already, these three algorithmic reductions are not incompatible. We just present them here due to their apparent explanatory power. A lot more theoretical work will be needed to make them quantitative and precise, but we are optimistic. The aim is now to develop an experimental framework to distinguish between the predictions that each candidate algorithmic reduction makes (including many not presented here). This is a work in progress.

Generalizing hyperbolization to non-spatial experiential fields

In the case of experiential fields such as body feelings, smells and concepts, the “hyperbolization” takes different forms depending on the algorithmic reduction you use. I prefer the very general interpretation that one experiences hyperbolic information geometry rather than just hyperbolic space. In other words, when we talk about body feelings and so on, on a psychedelic one organizes such information in a hyperbolic relational graph, which also exhibits a negative curvature relative to its normal geometry. Arguing in favor of this interpretation would take another article, so we will leave that for another time.

Getting a handle on the DMT state

Gluing a 1-handle is easy on a 2-sphere. Tongue in cheek, sticking a little doughnut on a big ball allows you to grab the sphere and control it in some way. But how do you get a handle on hyperbolic space? The answer is to build hyperbolic manifolds at the core of one’s being, by imagining knots very intensely. The higher one is, the more complex the knot one can imagine in detail. Having practiced visualizations of this sort while sober certainly helps. If you imagine the knot with enough detail, you can then stress the environment surrounding it to represent a warped hyperbolic space. This way you give life to the complement of the knot (which is almost always hyperbolic!). We postulate that it is possible to study in detail the relationship between the knots imagined, and the properties of the experiential worlds that result from their inversion (i.e. thinking about the geometry of the space surrounding the knot rather than the knot itself). A reports that different hyperbolic spaces generated this way (i.e. imagining knots on tryptamines) have different levels of energy, and have unique resonant properties. Different kinds of music feel better in different kinds of hyperbolic manifolds. It takes more energy to “light up” a hyperbolic space like that, mostly due to its openness. This is why using small doses of 2C-B can be helpful to create a positive backbone to the experience (providing the necessary warmth to light up the hyperbolic space). Admittedly MDMA tends to work best, but its use is unadvisable for reasons we will not get into (related to the hedonic treadmill). A healthy combination that both enables the visualization of the hyperbolic spaces in a vivid way and also lights them up with positive hedonic tone healthily and reliably has yet to be found.

Relatedly… Get a handle on your DMT trip by creating a stabilizing 4D hyperbolic manifold in four easy steps:

Unifying Your Space

God, the divine, open individualism, the number one, an abstract notion of self, or the thought of existence itself are all thoughts that work as great “unifiers” of large areas of phenomenal space. Indeed these concepts can allow a person to connect the edges of the hyperbolic space and create a pocket of one’s experience that does not seem to have a boundary yet is extremelly open. This may be a reason why such ideas are very common in high levels of psychedelia. In a sense, depending on the mind, they have at times the highest recruiting power for your multi-threaded attention.

Applications to Qualia Computing and Closing Thoughts

Beyond mere designer synesthesia, the future of consciousness research contains the possibility of exploring alternative geometries for the layout of our experiences. One’s overall level of energy, its manifestation, the allowed invariants, the logic gates, the differences in resonance, the granularity of the patterns, and so on, are all parameters that we will get to change in our minds to see what happens (in controlled and healthy ways, of course). The exploration of the state-space of consciousness is sure to lead to a combinatorial explosion. Even with good post-theoretical quantitative algorithmic reductions, it is likely that qualia computing scientists will still find an unfathomable number of distinct “prime” permutations. For some applications it may be more useful to use special kinds of hyperbolic spaces (like the compliment of certain class of knot), but for others it may suffice to be a little sphere. Who knows. In the end, if a valence economy ends up dominating the world, then the value of hyperbolic phenomenal spaces will be proportional to the level of wellbeing and bliss that can be felt in them. Which space in which resonant mode generates the highest level of bliss? This is an empirical question with far-reaching economic implications.

Mathematics post-hyperbolic consciousness

I predict that some time in the next century or so many of the breakthroughs in mathematics will take place in consciousness research centers. The ability to utilize arbitrary combinations of qualia with programable geometry and information content (in addition to our whole range of pre-existing cognitive skills) will allow people to have new semantic primitives related to mathematical structures and qualia systems currently unfathomable to us. In the end, studying the mathematics of consciousness and valence is perhaps the ultimate effective altruist endeavor in a world filled with suffering, since reverse-engineering valence would simplify paradise engineering… But even in a post-scarcity world, consciousness research will also probably be the ultimate past time given the endless new discoveries awaiting to be found in the state-space of consciousness.


*On the unexpected side effects of staring at a cauliflower on DMT: You can get lost in the hyperbolic reality of the (apparent) life force that spirals in a scale-free fractal fashion throughout the plant. The spirals may feel like magnetic vortexes that take advantage of your state to attract your attention. The cauliflower may pull you into its own world of interconnected fractals, and as soon as you start to trust it, it begins trying to recruit you for the cauliflower cause. The cauliflower may scare you into not eating it, and make you feel guilty about frying it. You may freak out a little, but when you come down you convince yourself that it was all just a hallucination. That said, you secretly worry it was for real. You may never choose to abstain from eating cauliflowers, but you will probably drop the knife when cooking it. You will break it apart with your own hands in the way you think minimizes its pain. You sometimes wonder whether it experiences agony as it is slowly cooked in the pan, and you drink alcohol to forget. Damn, don’t stare at a cauliflower while high on DMT if you ever intend to eat one again.

P.S. Note on Originality: The only mention I have been able to find that explicitly connects hyperbolic geometry in a literal sense with DMT (rather than just metaphorical talk of “hyperspace”) is a 2014 post in the Psychonaut subredit. To my knowledge, no one has yet elaborated to any substantial degree on this interesting connection. That said, I’m convinced that during the days that follow a strong trip, psychedelic self-experimenters may frequently wonder about the geometry of the places they explored. Yet they usually lack any conceptual framework to justify their intuitions or even verbalize them, so they quickly forget about them.

P.S.S. Example Self-Dribbling Basketball:

tumblr_mzwuhkg05b1svg5dto1_400

Self-dribbling basketball

To the right you can see what a “self-dribbling basketball” looks like. The more you try to “grasp” what it is, the more curved it gets. That’s because you are adding energy with you attention and you do not have enough recognition ability in this space to lower its energy and reduce the curvature to stabilize it. The curvature is so extreme at times that it produces constant “context switches”. This is the result of excess curvature being pushed towards the edge of your experience and turning into walls and corridors.

P.S.S.S.: Example on world-sheet bending:

Below you can find two gifs that illustrate the behavior of a world-sheet on a 5mg vs. 20mg dose. The speed at which you are adding curvature to it increases so much that the shapes and objects keep shifting to accommodate it all.

Panpsychism and Compositionality: A solution to the hard problem

By Anand Rangarajan

 

We begin with the assumption that all emergentist approaches are inadequate to solve the hard problem of experience. Consequently, it’s hard to escape the conclusion that consciousness is fundamental and that some form of panpsychism is true. Unfortunately, panpsychism faces the combination problem – why should proto-experiences combine to form full fledged experiences? Since the combination problem has resisted many attempts, we argue for compositionality as the missing ingredient needed to explain mid level experiences such as ours. Since this is controversial, we carefully present the full argument below. To begin, we assume, following Frege, that experience cannot exist without being accompanied by a subject of experience (SoE). An SoE provides the structural and spatio-temporally bounded “container” for experience and following Strawson is conceived as a thin subject. Thin subjects exhibit a phenomenal unity with different types of phenomenal content (sensations, thoughts etc.) occurring during their temporal existence. Next, following Stoljar, we invoke our ignorance of the true physical as the reason for the explanatory gap between present day physical processes (events, properties) and experience. We are therefore permitted to conceive of thin subjects as physical compositions. Compositionality has been an intensely studied area in the past twenty years. While there is no clear consensus here, we argue, following Koslicki, that a case can be made for a restricted compositionality principle and that thin subjects are physical compositions of a certain natural kind. In this view, SoEs are natural kind objects with a yet to be specified compositionality relation connecting them to the physical world. The specifics of this relation will be detailed by a new physics and at this juncture, all we can provide are guiding metaphors. We suggest that the relation binding an SoE to the physical is akin to the relation between a particle and field. In present day physics, a particle is conceived as a coherent excitation of a field and is spatially and temporally bounded (with the photon being the sole exception). Under the right set of circumstances, a particle coalesces out of a field and dissipates. We suggest that an SoE can be conceived as akin to a particle coalescing out of physical fields, persisting for a brief period of time and then dissipating – in a manner similar to the phenomenology of a thin subject. Experiences are physical properties of SoEs with the constraint (specified by a similarity metric) that SoEs belonging to the same natural kind will have similar experiences. The counter-intuitive aspect of this proposal is the unexpected “complexity” exhibited by SoE particles but we have been prepared for this by the complex behavior of elementary particles in over ninety years of experimental physics. Consequently, while it is odd at first glance to conceive of subjects of experience as particles, the spatial and temporal unity exhibited by particles as opposed to fields and the expectation that SoEs are new kinds of particles, paves the way for cementing this notion. Panpsychism and compositionality are therefore new bedfellows aiding us in resolving the hard problem.

Is it for real?

A sizable percentage of people who try a high dose of DMT end up convinced that the spaces they visit during the trip exist in some objective sense; they either suspect, intuit or conclude that their psychonautic experience reflects something more than simply the contents of their minds. Most scientists would argue that those experiences are just the result of exotic brain states; the worlds one travels to are bizarre (often useless) simulations made by our brain in a chaotic state. This latter explanation space forgoes alternate realities for the sake of simplicity, whereas the former envisions psychedelics as a multiverse portal technology of some sort.

Some exotic states, such as DMT breakthrough experiences, do typically create feelings of glimpsing foundational information about the depth and structure of the universe. Entity contact is frequent, and these seemingly autonomous DMT entities are often reported to have the ability to communicate with you. Achieving a verifiable contact with entities from another dimension would revolutionize our conception of the universe. Nothing would be quite as revolutionary, really. But how to do so? One could test the external reality of these entities by asking them to provide information that cannot be obtained unless they themselves held an objective existence. In this spirit, some have proposed to ask these entities complex mathematical questions that would be impossible for a human to solve within the time provided by the trip. This particular test is really cool, but it has the flaw that DMT experiences may themselves trigger computationally-useful synesthesia of the sort that Daniel Tammet experiences. Thus even if DMT entities appeared to solve extraordinary mathematical problems, it would still stand to reason that it is oneself who did it and that one is merely projecting the results into the entities. The mathematical ability would be the result of being lucky in the kind of synesthesia DMT triggered in you.

A common overarching description of the effects of psychedelics is that they “raise the frequency of one’s consciousness.” Now, this is a description we should take seriously whether or not we believe that psychedelics are inter-dimensional portals. After all, promising models of psychedelic action involve fast-paced control interruption, where each psychedelic would have its characteristic control interrupt frequency. And within a quantum paradigm, Stuart Hameroff has argued that psychedelic compounds work by bringing up the quantum resonance frequency of the water inside our neurons’ microtubules (perhaps going from megahertz to gigahertz), which he claims increases the non-locality of our consciousness.

In the context of psychedelics as inter-dimensional portals, this increase in the main frequency of one’s consciousness may be the key that allows us to interact with other realities. Users describe a sort of tuning of one’s consciousness, as if the interface between one’s self and the universe underwent some sudden re-adjustment in an upward direction. In the same vein, psychedelicists (e.g. Rick Strassman) frequently describe the brain as a two-way radio, and then go on to claim that psychedelics expand the range of channels we can be attuned to.

One could postulate that the interface between oneself and the universe that psychonauts describe has a real existence of its own. It would provide the bridge between us as (quantum) monads and the universe around us; and the particular structure of this interface would determine the selection pressures responsible for the part of the multiverse that we interact with. By modifying the spectral properties of this interface (e.g. by drastically raising the main frequency of its vibration) with, e.g. DMT, one effectively “relocates” (cf. alien travel) to other areas of reality. Assuming this interface exists and that it works by tuning into particular realities, what sorts of questions can we ask about its properties? What experiments could we conduct to verify its existence? And what applications might it have?

The Psychedelic State of Input Superposition

Once in a while I learn about a psychedelic effect that captures my attention precisely because it points to simple experiments that could distinguish between the two rough explanation spaces discussed above (i.e. “it’s all in your head” vs. “real inter-dimensional travel”). This article will discuss a very odd phenomenon whose interpretations do indeed have different empirical predictions. We are talking about the experience of sensing what appears to be a superposition of inputs from multiple adjacent realities. We will call this effect the Psychedelic State of Input Superposition (PSIS for short).

There is no known way to induce PSIS on purpose. Unlike the reliable DMT hyper-dimensional journeys to distant dimensions, PSIS is a rare closer-to-home effect and it manifests only on high doses of LSD (and maybe other psychedelics). Rather than feeling like one is tuning into another dimension in the higher frequency spectrum, it feels as if one just accidentally altered (perhaps even broke) the interface between the self and the universe in a way that multiplies the number of realities you are interacting with. After the event, the interface seems to tune into multiple similar universes at once; one sees multiple possibilities unfold simultaneously. After a while, one somehow “collapses” into only one of these realities, and while coming down, one is thankful to have settled somewhere specific rather than remaining in that weird in-between. Let’s take a look at a couple of trip reports that feature this effect:

[Trip report of taking a high dose of LSD on an airplane]: So I had what you call “sonder”, a moment of clarity where I realized that I wasn’t the center of the universe, that everyone is just as important as me, everyone has loved ones, stories of lost love etc, they’re the main character in their own movies.

 

That’s when shit went quantum. All these stories begun sinking in to me. It was as if I was beginning to experience their stories simultaneously. And not just their stories, I began seeing the story of everyone I had ever met in my entire life flash before my eyes. And in this quantum experience, there was a voice that said something about Karma. The voice told me that the plane will crash and that I will be reborn again until the quota of my Karma is at -+0. So, for every ill deed I have done, I would have an ill deed committed to me. For every cheap T-shirt I purchased in my previous life, I would live the life of the poor Asian sweatshop worker sewing that T-shirt. For every hooker I fucked, I would live the life of a fucked hooker.

 

And it was as if thousands of versions of me was experiencing this moment. It is hard to explain, but in every situation where something could happen, both things happened and I experienced both timelines simultaneously. As I opened my eyes, I noticed how smoke was coming out of the top cabins in the plane. Luggage was falling out. I experienced the airplane crashing a thousand times, and I died and accepted death a thousand times, apologizing to the Karma God for my sins. There was a flash of the brightest white light imagineable and the thousand realities in which I died began fading off. Remaining was only one reality in which the crash didn’t happen. Where I was still sitting in the plane. I could still see the smoke coming out of the plane and as a air stewardess came walking by I asked her if everything was alright. She said “Yes, is everything alright with YOU?”.

Further down on the same thread, written by someone else:

[A couple hours after taking two strong hits of LSD]: Fast-forward to when I’m peaking hours later and I find myself removed from the timeline I’m in and am watching alternate timelines branch off every time someone does something specific. I see all of these parallel universes being created in real time, people’s actions or interactions marking a split where both realities exist. Dozens of timelines, at least, all happening at once. It was fucking wild to witness.

 

Then I realize that I don’t remember which timeline I originally came out of and I start to worry a bit. I start focusing, trying to remember where I stepped out of my particular universe, but I couldn’t figure it out. So, with the knowledge that I was probably wrong, I just picked one to go back into and stuck with it. It’s not like I would know what changed anyway, and I wasn’t going to just hang out here in the whatever-this-place-is outside of all of them.

 

Today I still sometimes feel like I left a life behind and jumped into a new timeline. I like it, I feel like I left a lot of baggage behind and there are a lot of regrets and insecurities I had before that trip that I don’t have anymore. It was in a different life, a different reality, so in this case the answer I found was that it’s okay to start over when you’re not happy with where you are in life.

 

— GatorAutomator

Let us summarize: Person X takes a lot of LSD. At some point during the trip (usually after feeling that “this trip is way too intense for me now”) X starts experiencing sensory input from what appear to be different branches of the multiverse. For example, imagine that person X can see a friend Y sitting on a couch in the corner. Suppose that Y is indecisive, and that as a result he makes different choices in different branches of the multiverse. If Y is deciding whether to stand up or not, X will suddenly see a shadowy figure of Y standing up while another shadowy figure of Y remains sitting. Let’s call them Y-sitting and Y-standing. If Y-standing then turns indecisive about whether to drink some water or go to the bathroom, X may see one shadowy figure of Y-standing getting water and a shadowy figure of Y-standing walking towards the bathroom, all the while Y-sitting is still on the couch. And so it goes. The number of times per second that Y splits and the duration of the perceived superposition of these splits may be a function of X’s state of consciousness, the substance and dose consumed, and the degree of indecision present in Y’s mind.

The two quotes provided are examples of this effect, and one can find a number of additional reports online with stark similarities. There are two issues at hand here. First, what is going on? And second, can we test it? We will discuss three hypotheses to explain what goes on during PSIS, propose an experiment to test the third one (the Quantum Hypothesis), and provide the results of such an experiment.

Hard-nosed scientists may want to skip to the “Experiment” section, since the following contains a fair amount of speculation (you have been warned).

Three Hypothesis for PSIS: Cognitive, Spiritual, Quantum

In order to arrive at an accurate model of the world, one needs to take into account both the prior probability of the hypothesis and the likelihoods that they predict that one would obtain the available evidence. Even if one prior of yours is extremely strong (e.g. a strong belief in materialism), it is still rational to update one’s probability estimates of alternative hypotheses when new relevant evidence is provided. The difficulty often comes from finding experiments where the various hypotheses generate very different likelihoods for one’s observations.  As we will see, the quantum hypothesis has this characteristic: it is the only one that would actually predict a positive result for the experiment.

The Cognitive Hypothesis

The first (and perhaps least surreal) hypothesis is that PSIS is “only in one’s mind”. When person X sees person Y both standing up and staying put, what may be happening is that X is receiving photons only from Y-standing and that Y-sitting is just a hallucination that X’s inner simulation of her environment failed to erase.

Psychedelics intensify one’s experience, and this is thought to be the result of control interruption. This means that inhibition of mental content by cortical feedback is attenuated. In the psychedelic state, sensory impressions, automatic reactions, feelings, thoughts and all other mental contents are more intense and longer-lived. This includes the predictions that you make about how your environment will evolve. Not only is one’s sensory input perceived as more intense, one’s imagined hypotheticals are also perceived more intensely.

Under normal circumstances, cortical inhibition makes our failed predictions quickly disappear. Psychedelic states of consciousness may be poor at inhibiting these predictions. In this account, X may be experiencing her brain’s past predictions of what Y could have done overlaid on top of the current input that she is receiving from her physical environment. In a sense, she may be experiencing all of the possible “next steps” that she simply intuited. While these simulations typically remain below the threshold of awareness (or just above it), on a psychedelic state they may reinforce themselves in unpredictable ways. X’s mind never traveled anywhere and there is nothing really weird going on. X is just experiencing the aftermath of a specific failure of information processing concerning the inhibition of past predictions.

Alternatively, very intense emotions such as those experienced on intense ego-killing psychedelic experiences may distort one’s perception so much that one begins to suspect that one is perhaps dead or in another dimension. We can posit that the belief that one is not properly connected to one’s brain (or that one is dying) can trigger even stronger emotions and unleash a cascade of further distortions. This positive feedback loop may create episodes of intense confusion and overlapping pieces of information, which later might be interpreted as “seeing splitting universes”.

The Spiritual Hypothesis

Many spiritual traditions postulate the existence of alternate dimensions, additional layers of reality, and hidden spirit pathways that connect all of reality. These traditions often provide rough maps of these realities and may claim that some people are able to travel to such far-out regions with mental training and consciousness technologies. For illustration, let’s consider Buddhist cosmology, which describes 31 planes of existence. Interestingly, one of the core ideas of this cosmology is that the major characteristic that distinguishes the planes of existence is the states of consciousness typical of their inhabitants. These states of consciousness are correlated with moral conditions such as the ethical quality of their past deeds (karma), their relationship with desire (e.g. whether it is compulsive, sustainable or indifferent) and their existential beliefs. In turn, a feature of this cosmology is that it allows inter-dimensional travel by changing one’s state of consciousness. The part of the universe one interacts with is a function of one’s karma, affinities and beliefs. So by changing these variables with meditation (or psychedelic medicine) one can also change which world we exist in.

An example of a very interesting location worth trying to travel to is the mythical city of Shambhala, the location of the Kalachakra Tantra. This city has allegedly turned into a pure land thanks to the fact that its king converted to Buddhism after meeting the Buddha. Pure lands are abodes populated by enlightened and quasi-enlightened beings whose purpose is to provide an optimal teaching environment for Buddhism. One can go to Shambhala by either reincarnating there (with good karma and the help of some pointers and directions at the time of death) or by traveling there directly during meditation. In order to do the latter, one needs to kindle one’s subtle energies so that they converge on one’s heart, while one is embracing the Bodhisattva ethic (focusing on reducing others’ suffering as a moral imperative). Shambhala may not be in a physical location accessible to humans. Rather, Buddhist accounts would seem to depict it as a collective reality built by people which manifests on another plane of existence (specifically somewhere between the 23rd and 27th layer). In order to create a place like that one needs to bring together many individuals in a state of consciousness that exhibits bliss, enlightenment and benevolence. A pure land has no reality of its own; its existence is the result of the states of consciousness of its inhabitants. Thus, the very reason why Shambhala can even exist as a place somewhere outside of us is because it is already a potential place that exists within us.

Similar accounts of a wider cosmological reality can be found elsewhere (such as Hinduism, Zoroastrianism, Theosophy, etc.). These accounts may be consistent with the sort of experiences having to do with astral travel and entity contact that people have while on DMT and other psychedelics in high doses. However, it seems a lot harder to explain PSIS with an ontology of this sort. While reality is indeed portrayed as immensely vaster than what science has shown so far, we do not really encounter claims of parallel realities that are identical to ours except that your friend decided to go to the bathroom rather than drink some water just now. In other words, while many spiritual ontologies are capable of accommodating DMT hyper-dimensional travel, I am not aware of any spiritual worldview that also claims that whenever two things can happen, they both do in alternate realities (or, more specifically, that this leads to reality splitting).

The only spiritual-sounding interpretation of PSIS I can think of is the idea that these experiences are the result of high-level entities such as guardians, angels or trickster djinns who used your LSD state to teach you a lesson in an unconventional way. The first quote (the one written by Reddit user I_DID_LSD_ON_A_PLANE) seems to point in this direction, where the so-called Karma God is apparently inducing a PSIS experience and using it to illustrate the idea that we are all one (i.e. Open Individualism). Furthermore, the experience viscerally portrays the way that this knowledge should impact our feelings of self-importance (by creating a profound feeling of sonder). This way, the tripper may develop a lasting need to work towards peace, wisdom and enlightenment for the benefit of all sentient beings.

Life as a learning experience is a common trope among spiritual worldviews. It is likely that the spiritual interpretations that emerge in a state of psychedelic depersonalization and derealization will depend on one’s pre-existing ideas of what is possible. The atonement of one’s sins, becoming aware of one’s karma, feeling our past lives, realizing emptiness, hearing a dire mystical warning, etc. are all ideas that already exist in human culture. In an attempt to make sense- any sense- of the kind of qualia experienced in high doses of psychedelics, our minds may be forced to instantiate grandiose delusions drawn from one’s reservoir of far-out ideas.

On a super intense psychedelic experience in which one’s self-models fail dramatically and one experiences fear of ego dissolution, interpreting what is happening as the result of the Karma God judging you and then giving you another chance at life can viscerally seem to make a lot of sense at the time.

The Quantum Hypothesis

For the sake of transparency I must say that we currently do not have a derivation of PSIS from first principles. In other words, we have not yet found a way to use the postulates of quantum mechanics to account for PSIS (that is, assuming that the cognitive and spiritual hypothesis are not the case). That said, there are indeed some things to be said here: While a theory is missing, we can at least talk about what a quantum mechanical account of PSIS would have to look like. I.e. we can at least make sense of some of the features that the theory would need to have to predict that people on LSD would be able to see the superposition of macroscopic branches of the multiverse.

Why would being on acid allow you to receive input from macroscopic environments that have already decohered? How could taking LSD possibly prevent the so-called collapse of the wavefunction? You might think: “well, why even think about it? It’s simply impossible because the collapse of the wavefunction is an axiom of quantum mechanics and we know it is true because some of the predictions made by quantum mechanics (such as QED) are in agreement with experimental data up to the 12th decimal point.” Before jumping to this conclusion, though, let us remember that there are several formulations of quantum mechanics. Both the Born rule (which determines the probability of seeing different outcomes from a given quantum measurement) and the collapse of the wavefunction (i.e. that any quantum state other than the one that was measured disappears) are indeed axiomatic for some formulations. But other formulations actually derive these features and don’t consider them fundamental. Here is Sean Carroll explaining the usual postulates that are used to teach quantum mechanics to undergraduate audiences:

The status of the Born Rule depends greatly on one’s preferred formulation of quantum mechanics. When we teach quantum mechanics to undergraduate physics majors, we generally give them a list of postulates that goes something like this:

  1. Quantum states are represented by wave functions, which are vectors in a mathematical space called Hilbert space.
  2. Wave functions evolve in time according to the Schrödinger equation.
  3. The act of measuring a quantum system returns a number, known as the eigenvalue of the quantity being measured.
  4. The probability of getting any particular eigenvalue is equal to the square of the amplitude for that eigenvalue.
  5. After the measurement is performed, the wave function “collapses” to a new state in which the wave function is localized precisely on the observed eigenvalue (as opposed to being in a superposition of many different possibilities).

In contrast, here is what you need to specify for the Everett (Multiple Worlds) formulation of quantum mechanics:

  1. Quantum states are represented by wave functions, which are vectors in a mathematical space called Hilbert space.
  2. Wave functions evolve in time according to the Schrödinger equation.

And that’s it. As you can see this formulation does not employ any collapse of the wavefunction, and neither does it consider the Born rule as a fundamental law. Instead, the wavefunction is thought to merely seem to collapse upon measurement (which is achieved by nearly diagonalizing its components along the basis of the measurement; strictly speaking, neighboring branches never truly stop interacting, but the relevance of their interaction approaches zero very quickly). Here the Born rule is derived from first principles rather than conceived as an axiom. How exactly one can derive the Born rule is a matter of controversy, however. Currently, two very promising theoretical approaches to do so are Quantum Darwinism and the so-called Epistemic Separability Principle (ESP for short, a technical physics term not to be confused with Extra Sensory Perception). Although these approaches to deriving the Born rule are considered serious contenders for a final explanation (and they are not mutually exclusive), they have been criticized for being somewhat circular. The physics community is far from having a consensus on whether these approaches truly succeed.

Is there any alternative to either axiomatizing or deriving the apparent collapse and the Born rule? Yes, there is an alternative: we can think of them as regularities contingent upon certain conditions that are always (or almost always) met in our sphere of experience, but that are not a universal fact about quantum mechanics. Macroscopic decoherence and Born rule probability assignments work very well in our everyday lives, but they may not hold universally. In particular -and this is a natural idea to have under any view that links consciousness and quantum mechanics- one could postulate that one’s state of consciousness influences the mind-body interaction in such a way that information from one’s quantum environment seeps into one’s mind in a different way.

Don’t get me wrong; I am aware that the Born rule has been experimentally verified with extreme precision. I only ask that you bear in mind that many scientific breakthroughs share a simple form: they question the constancy of certain physical properties. For example, Einstein’s theory of special relativity worked out the implications of the fact that the speed of light is observer-independent. In turn this makes the passage of time of external systems observer-dependent. Scientists had a hard time believing Einstein when he arrived at the conclusion that accelerating our frame of reference to extremely high velocities could dilate time. What was thought to be a constant (the passage of time throughout the universe) turned out to be an artifact of the fact that we rarely travel fast enough to notice any deviation from Newton’s laws of motion. In other words, our previous understanding was flawed because it assumed that certain observations did not break down in extreme conditions. Likewise, maybe we have been accidentally ignoring a whole set of physically relevant extreme conditions: altered states of consciousness. The apparent wavefunction collapse and the Born rule may be perfectly constant in our everyday frame of reference, and yet variable across the state-space of possible conscious experiences. If this were the case, we’d finally understand why it seems so hard to derive the Born rule from first principles: it’s impossible.

Succinctly, the Quantum Hypothesis is that psychedelic experiences modify the way one’s mind interacts with its quantum environment in such a way that the world does not appear to decohere any longer from one’s point of view. Our ignorance about the non-universality of the apparent collapse of the wavefunction is just a side effect of the fact that physicists do not usually perform experiments during intense life-changing entheogenic mind journeys. But for science, today we will.

Deriving PSIS with Quantum Mechanics

Here we present a rough (incomplete) sketch of what a possible derivation of PSIS from quantum mechanics might look like. To do so we need three background assumptions: First, conscious experiences must be macroscopic quantum coherent objects (i.e. ontologically unitary subsets of the universal wavefunction, akin to super-fluid helium or Bose–Einstein condensates, except at room temperature). Second, people’s decision-making process must somehow amplify low-level quantum randomness into macroscopic history bifurcations. And third, the properties of our quantum environment* are in part the result of the quantum state of our mind, which psychedelics can help modify. This third assumption brings into play the idea that if our mind is more coherent (e.g. is in a super-symmetrical state) it will select for wavefunctions in its environment that themselves are more coherent. In turn, the apparent lifespan of superpositions may be elongated long enough so that the quantum environment of one’s mind receives records from both Y-sitting and Y-standing as they are overlapping. Now, how credible are these three assumptions?

That events of experience are macroscopic quantum coherent objects is an explanation space usually perceived as pseudo-scientific, though a sizable number of extremely bright scientists and philosophers do entertain the idea very seriously. Contrary to popular belief, there are legitimate reasons to connect quantum computing and consciousness. The reasons for making this connection include the possibility of explaining the causal efficacy of consciousness, finding an answer to the palette problem with quantum fields and solving the phenomenal binding problem with quantum coherence and panpsychism.

The second assumption claims that people around you work as quantum Random Number Generators. That human decision-making amplifies low-level quantum randomness is thought to be likely by at least some scientists, though the time-scale on which this happens is still up for debate. The brain’s decision-making is chaotic, and over the span of seconds it may amplify quantum fluctuations into macroscopic differences. Thus, people around you making decisions may result in splitting universes (e.g. “[I] am watching alternate timelines branch off every time someone does something specific.” – GatorAutomator’s quote above). Presumably, this assumption would also imply that during PSIS not only people but also physics experiments would lead to apparent macroscopic superposition.

With regards to the third assumption: widespread microscopic decoherence is not, apparently, a necessary consequence of the postulates of quantum mechanics. Rather, it is a very specific outcome of (a) our universe’s Hamiltonian and (b) the starting conditions of our universe, i.e. Pre-Inflation/Eternal Inflation/Big Bang. (A Ney & D Albert, 2013). In principle, psychedelics may influence the part of the Hamiltonian that matters for the evolution of our mind’s wavefunction and its local interactions. In turn, this may modify the decoherence patterns of our consciousness with its local environment and- perhaps- ultimately the surrounding macroscopic world. Of course we do not know if this is possible, and I would have to agree that it is extremely far-fetched.

The overall picture that would emerge from these three assumptions would take the following form: both the mental content and raw phenomenal character of our states of consciousness are the result of the quantum micro-structure of our brains. By modifying this micro-structure, one is not only altering the selection pressures that give rise to fully formed experiences (i.e. quantum darwinism applied to the compositionality of quantum fields) but also altering the selection pressures that determine which parts of the universal wave-function we are entangled with (i.e. quantum darwinism applied to the interactions between coherent objects). Thus psychedelics may not only influence how our experience is shaped within, but also how it interacts with the quantum environment that surrounds it. Some mild psychedelic states (e.g. MDMA) may influence mostly the inner degrees of freedom of one’s mind, while other more intense states (e.g. DMT) may be the result of severe changes to the entanglement selection pressures and thus result in the apparent disconnection between one’s mind and one’s local environment. Here PSIS would be the result of decreasing the rate at which our mind decoheres (possibly by increasing the degree to which our mind is in a state of quantum confinement). In turn, by boosting one’s own inner degree of quantum superposition one may also broaden the degree of superposition acceptable at the interface with one’s quantum environment. One could now readily take in packets of information that have a wider degree of superposition. In the right circumstances, this may result in one’s mind experiencing information seemingly coming from alternate branches of the multiverse. In other words, the trick to PSIS both in the Quantum and the Spiritual Hypothesis is the same (though for different reasons): travel to other dimensions by being the change that you wish to see in the world. You need to increase your own degree of quantum coherence so that you become able of interacting with a more coherent quantum environment.

If this were the case it would call for a conceptual revolution. We would stop thinking of “our universe” as the “place we inhabit” and instead think of it as “the quantum environment our consciousness can interface with”. Perhaps life as we know it exists in a quantum niche that can give rise to embodied biological beings, but the universal wavefunction also contains alien state-spaces in which the patterns of entanglement work in different ways and lead to different evolutionary histories. Our minds evolved to interact with the particular environment that leads to the sustenance of our everyday macroscopic world. Our consciousness is shaped to fit in here, and it has a symbiotic relationship with the body that hosts it.

Now, how do we go about testing the quantum hypothesis? Following previous work on psychophysics for psychedelic research, the main idea will be to show that people on psychedelics can achieve something that sober individuals can’t. In this case, the task is designed to be impossible if one is only receiving input from one world (as predicted by the cognitive hypothesis). Only if PSIS is the result of simultaneously experiencing input from the several nearby branches that correspond to different outcomes of quantum events can the task be successfully performed.

The Experiment

Setup

The task in question involves three white little squares on a black background. At each time step (~16 milliseconds) the squares move one pixel down, and some number of pixels horizontally. While the downward movement is constant, the change in the horizontal direction is chosen randomly. The horizontal movement of one of the squares is being randomized on the fly with a Quantum Random Number Generator (qRNG**). We call this the quantum square. The horizontal movement of the other two squares follows a path that was determined at the beginning of each trial by a Classical Random Number Generator (cRNG***). We will refer to these two squares as the classical squares. The task for the participant is to identify which of the squares is the “odd one out” (i.e. the quantum square). Here is an infographic that explains the experimental setup:

infografic_of_experiment.png

In order to make the horizontal movement seem very chaotic and, at times even dramatic, it is randomized by choosing a horizontal change of either -4, -1, 1 or 4 pixels. By using a jump of 4 pixels (rather than e.g. 2) the squares sometimes seem to advance very quickly in one direction. The rationale for doing this was to make the predicted effect (assuming the Quantum Hypothesis) more noticeable – we want low probability paths that are extremely different than the typical path and in turn make it easy to distinguish between single paths and the superposition of many of the possible paths at once.

Critically, the starting position of the quantum square (whether left, center or right) for each of the trials during an experiment is obtained with a cRNG at the very beginning of the experiment. Why not use a qRNG? If we randomized the position of the quantum square using a qRNG we might be sabotaging ourselves: participants might see a superposition of classical and quantum squares on each of the three positions and thus not see any square behave differently than the other two. Thus, for the experiment to work (under the assumption that PSIS is explained by the Quantum Hypothesis) the only aspect that should be randomized using a qRNG is the horizontal displacement of the quantum square.

Since the numbers coming from the qRNG need to be requested over the internet, it is also crucial that we try to obtain fresh quantum random numbers as frequently as possible without messing up the flow of the experiment. Thus, a request for new quantum random numbers is made as often as possible (usually every 1 to 2 seconds). Since internet connections, server response time and network reliability varies from moment to moment, it is inevitable that once in a while we will have to stop the downward movement of all three squares as we wait for the next batch of random numbers. In principle this should have no negative effect at all in the ability to choose the odd-one-out. This problem merely interrupts the flow of the experiment, but it should not invalidate the results. We kept track of the number of trials that were interrupted for this reason (which you will find recorded in the “Network” column of the table of results down below).

Participants were instructed to:

  1. Clone the Github code for the experiment, and to open it up in a Chrome browser.
  2. Make sure that they have a reliable high-speed internet connection.
  3. Record the pertinent facts (time of experiment, substance, dose and time of intake).
  4. Use a sensorially-minimized room for the experiment (such as a closed bathroom), turn off the lights, ask anyone who is in the house to be quiet and mind their own business, and wear earplugs.
  5. Meditate for a couple of minutes before conducting the experiment and to try to induce PSIS voluntarily.
  6. Choose the odd-one-out (i.e. the quantum square) on each trial, for a total of at least 30 trials.

Under this setup, what should the participants expect to see if the Quantum Hypothesis is correct?

Predicted Psychedelic Perception

The pictures above illustrate how the experiment looks like to three different observers. On the left we see what a sober participant would see at a given time during a trial. The squares are moving downwards but since we are taking a snapshot in time they seem to be static. The image on the center shows what we would expect out of a generic psychedelic experience. In brief, the typical control interrupt action of psychedelics (i.e. tracers) effectively allows you to see more clearly the path that the squares have traced over time, but it would not allow you to notice any difference between the classic and quantum squares. The image on the right shows what we would expect to see if the Quantum Hypothesis is correct and PSIS is actually about perceiving nearby branches of the Everett multiverse. Notice how the center square is visibly different than the other two: it consists of the superposition of many alternative paths the square took in slightly different branches.

Implications of a Positive Result: Quantum Mind, Everett Rescue Missions and Psychedelic Cryptography

It is worth noting that if one can indeed reliably distinguish between the quantum and the classical squares, then this would have far-reaching implications. It would indeed confirm that our minds are macroscopic quantum coherent objects and that psychedelics influence their pattern of interactions with their surrounding quantum environment. It would also provide strong evidence in favor of the Everett interpretation of quantum mechanics (in which all possibilities are realized). More so, we would not only have a new perspective on the fundamental nature of the universe and the mind, but the discovery would just as well suggest some concrete applications. Looking far ahead, a positive outcome is that this knowledge would encourage research on the possible ways to achieve inter-dimensional travel, and in turn instantiate pan-Everettian rescue missions to reduce suffering elsewhere in the multiverse. The despair of confirming that the quantum multiverse is real might be evened out by the hope of finally being able to help sentient beings trapped in Darwinian environments in other branches of the universal wavefunction. Looking much closer to home, a positive result would lead to a breakthrough in psychedelic cryptography (PsyCrypto for short), where spies high on LSD would obtain the ability to read information that is secretly encoded in public light displays. More so, this particular kind of PsyCrypto would be impervious to discovery after the fact. Even if given an arbitrary amount of time and resources to analyze a video recording of the event, it would not be possible to determine which of the squares was being guided by quantum randomness. Unlike other PsyCrypto techniques, this one cannot be decoded by applying psychedelic replication software to video recordings of the transmission.

Results

Three persons participated in the experiments: S (self), A, and B. [A and B are anonymous volunteers; for more information read the legal disclaimer at the end of this article]. Participant S (me) tried the experiment both sober and after drinking 2 beers. Participant A tried the experiment sober, on LSD, 2C-B and a combination of the two. And participant B tried the experiment both sober and on DMT. The total number of trials recorded for each of the conditions is: 90 for the sober state, 275 for 2C-B, 60 for DMT, 120 for LSD and 130 for the LSD/2C-B combo. The overall summary of the results is: chance level performance outcomes for all conditions. You can find the breakdown of results for all experiments in the table shown below, and you can download the raw csv file from the Github repository.

Columns from left to right: Date, State (of consciousness), Dose(s), T (time), #Trials (number of trials), Correct (number of trials in which the participant made the correct choice), Percent correct (100*Correct/Trials), Participants (S=Self, A/B=anonymous volunteers), Requests / Second (server requests per second), Network (this tracks the number of times that a trial was temporarily paused while the browser was waiting for the next batch of quantum random numbers), Notes (by default the squares left a dim trail behind them and this was removed in two trials; by default the squares were 10×10 pixels in size, but a smaller size was used in some trials).

I thought about visualizing the results in a cool graph at first, but after I received them I realized that it would be pointless. Not a single experiment reached a statistically significant deviation from chance level; who is interested in seeing a bunch of bars representing chance-level outcomes? Null results are always boring to visualize.****

In addition to the overall performance in the task, I also wanted to hear the following qualitative assessment from the participants: did they notice any difference between the three squares? Was there any feeling that one of them was behaving differently than the other two? This is what they responded when I asked them: “I could never see any difference between the squares, so it felt like I was making random choices” (from A) and “DMT made the screen look like a hyper-dimensional tunnel and I felt like strange entities were watching over me as I was doing the experiment, and even though the color of the squares would fluctuate randomly, I never noticed a single square behaving differently than the other two. All three seemed unique. I did feel that the squares were being controlled by some entity, as if with an agency of their own, but I figured that was made up by my mind.” When I asked them if they noticed anything similar to the image labeled Psychedelic view as predicted by the Quantum Hypothesis (as shown above) they both said “no”.

Discussion

It is noteworthy that neither participant reported an experience of PSIS during the experiments. Even without an explicit and noticeable input superposition, PSIS may turn out to be a continuum rather than a discrete either-or phenomenon. If so, we might still expect to see some deviations from chance. This may be analogous to how in blindsight people report not being able to see anything and yet perform better than chance in visual recognition tasks. That said, the effect size of blindsight and other psychological effects in which information is processed unbeknownst to the participant tend to be very small. Thus, in order to confirm that quantum PSIS is happening below the threshold of awareness we may require a much larger number of samples (though still a lot smaller than what we would need if we were aiming to use the experiment to conduct Psi research with or without psychedelics, again, due to the extremely small effect sizes).

Why did the experiment fail? The first possibility is that it could be that the Quantum Hypothesis is simply wrong (and possibly because it requires false assumptions to work). Second, perhaps we were simply unlucky that PSIS was not triggered during the experiments; perhaps the set, setting, and dosages used simply failed to produce the desired effect (even if the state does indeed exist out there). And third, the experiment itself may be wrong: the second-long delays between the server requests and the qRNG may be too large to produce the effect. In the current implementation (and taking into account network delays), the average delay between the moment the quantum measurement was conducted and the moment it appeared on the computer screen as horizontal movement was .9 seconds (usually in the range of .4 to 1.4 seconds, given an average of 1/2 second lag due to the number buffering and 400 milliseconds in network time). This problem would be easily sidestepped if we used an on-site qRNG obtained from hardware directly connected to the computer (as is common in psi research). To minimize the delay even further, the outcomes of the quantum measurements could be delivered directly to your brain via neuroimplants.

Conclusion

If psychedelic experiences do make you interact with other realities, I would like to know about it with a high degree of certainty. The present study was admittedly a very long shot. But to my judgement, it was totally worth it. As Bayesians, we reasoned that since the Quantum Hypothesis can lead to a positive result for the experiment but the Cognitive Hypothesis can’t, then a positive result should make us update our probabilities of the Quantum Hypothesis a great deal. A negative result should make us update our probabilities in the opposite direction. That said, the probability should still not go to zero since the negative result could still be accounted for by the fact that participants failed to experience PSIS, and/or that the delay between the quantum measurement and the moment it influences the movement of the square in the screen is too large. Future studies should try to minimize these two possible sources of failure. First, by researching methods to reliably induce PSIS. And second, by minimizing the delay between branching and sensory input.

In the meantime, we can at least tentatively conclude that something along the lines of the Cognitive Hypothesis is the most likely case. In this light, PSIS turns out to be the result of a failure to inhibit predictions. Despite losing their status as suspected inter-dimensional portal technology, psychedelics still remain a crucial tool for qualia research. They can help us map out the state-space of possible experiences, allow us to identify the computational properties of consciousness, and maybe even allow us to reverse engineer the fundamental nature of valence.


[Legal Disclaimer]: Both participants A and B contacted me some time ago, soon after the Qualia Computing article How to Secretly Communicate with People on LSD made it to the front page of Hacker News and was linked by SlateStarCodex. They are both experienced users of psychedelics who take them about once a month. They expressed their interest in performing the psychophysics experiments I designed, and to do so while under the influence of psychedelic drugs. I do not know these individuals personally (nor do I know their real names, locations or even their genders). I have never encouraged these individuals to take psychedelic substances and I never gave them any compensation for their participation in the experiment. They told me that they take psychedelics regularly no matter what, and that my experiments would not be the primary reason for taking them. I never asked them to take any particular substance, either. They just said “I will take substance X on day Y, can I have some experiment for that?” I have no way of knowing (1) if the substances they claim they take are actually what they think they are, (2) whether the dosages are accurately measured, and (3) whether the data they provided is accurate and isn’t manipulated. That said, they did explain that they have tested their materials with chemical reagents, and are experienced enough to tell the difference between similar substances. Since there is no way to verify these claims without compromising their anonymity, please take the data with a grain of salt.

* In this case, the immediate environment would actually refer to the quantum degrees of freedom surrounding our consciousness within our brain, not the macroscopic exterior vicinity such as the chair we are sitting on or the friends we are hanging out with. In this picture, our interaction with that vicinity is actually mediated by many layers of indirection.

** The experiment used the Australian National University Quantum Random Numbers Server. By calling their API every 1 to 2 seconds we obtain truly random numbers that feed the x-displacement of the quantum square. This is an inexpensive and readily-available way to magnify decoherence events into macroscopic splitting histories in the comfort of your own home.

*** In this case, Javascript’s Math.random() function. Unfortunately the RGN algorithm varies from browser to browser. It may be worthwhile to go for a browser-independent implementation in the future to guarantee a uniform high quality source of classical randomness.

**** As calculated with a single tailed binomial test with null probability equal to 1/3. The threshold of statistical significance at the p < 0.05 level is found at 15/30 and for p < 0.001 we need at least 19/30 correct responses. The best score that any participant managed to obtain was 14/30.

A Single 3N-Dimensional Universe: Splitting vs. Decoherence

A common way of viewing Everettian quantum mechanics is to say that in an act of measurement, the universe splits into two. There is a world in which the electron has x-spin up, the pointer points to “x-spin up,” and we believe the electron has x-spin up. There is another world in which the electron has x-spin down, the pointer points to “x-spin down,” and we believe the electron has x-spin down. This is why Everettian quantum mechanics is often called “the many worlds interpretation.” Because the contrary pointer readings exist in different universes, no one notices that both are read. This way of interpreting Everettian quantum mechanics raises many metaphysical difficulties. Does the pointer itself split in two? Or are there two numerically distinct pointers? If the whole universe splits into two, doesn’t this wildly violate conservation laws? There is now twice as much energy and momentum in the universe than there was just before the measurement. How plausible is it to say that the entire universe splits?

 

Although this “splitting universes” reading of Everett is popular (Deutsch 1985 speaks this way in describing Everett’s view, a reading originally due to Bryce Dewitt), fortunately, a less puzzling interpretation has been developed. This idea is to read Everett’s theory as he originally intended. Fundamentally, there is no splitting, only the evolution of the wave function according to the Shrödinger dynamics. To make this consistent with experience, it must be the case that there are in the quantum state branches corresponding to what we observe. However, as, for example, David Wallace has argued (2003, 2010), we need not view these branches -indeed, the branching process itself- as fundamental. Rather, these many branches or many worlds are patterns in the one universal quantum state that emerge as the result of its evolution. Wallace, building on work by Simon Saunders (1993), argues that there is a kind of dynamical process; the technical name for this process is “decoherence,” that can ground the emergence of quasi-classical branches within the quantum state. Decoherence is a process that involves an interaction between two systems (one of which may be regarded as a system and the other its environment) in which distinct components of the quantum state come to evolve independently of one another. That this occurs is the result of the wave function’s Hamiltonian, the kind of system it is. A wave function that (due to the kind of state it started out in and the Shrödinger dynamics) exhibits decoherence will enter into states capable of representation as a sum of noninteracting terms in particular basis (e.g., a position basis). When this happens, the system’s dynamics will appear classical from the perspective of the individual branches.

 

[…]

 

Note the facts about the quantum state decohering are not built into the fundamental laws. Rather, this is an accidental fact depending on the kind of state our universe started out in. The existence of these quasi-classical states is not a fundamental fact either, but something that emerges from the complex behavior of the fundamental state. The sense in which there are many worlds in this way of understanding Everettian quantum mechanics is therefore not the same as it is on the more naive approach already described. Fundamentally there is just one universe evolving according to the Schrödinger equation (or whatever is its relativistically appropriate analog). However, because of the special way this one world evolves, and in particular because parts of this world do not interfere with each other and can each on their own ground the existence of quasi-classical macro-objects that look like individual universes, it is correct in this sense to say (nonfundamentally) there are many worlds.

 

[…]

 

As metaphysicians, we are interested in the question of what the world is fundamentally like according to quantum mechanics. Some have argued that the answer these accounts give us (setting aside Bohmian mechanics for the moment) is that fundamentally all one needs to believe in is the wave function. What is the wave function? It is something that as we have already stated may be described as a field on configuration space, a space where each point can be taken to correspond to a configuration of particles, a space that has 3N dimensions where N is the number of particles. So, fundamentally, according to these versions of quantum mechanics (orthodox quantum mechanics, Everettian quantum mechanics, spontaneous collapse theories), all there is fundamentally is a wave function, a field in a high-dimensional configuration space. The view that the wave function is a fundamental object and a real, physical field on configuration space is today referred to as “wave function realism.” The view that such a wave function is everything there is fundamentally is wave function monism.

 

To understand wave function monism, it will be helpful to see how it represents the space on which the wave function is spread. We call this space “configuration space,” as is the norm. However, note that on the view just described, this is not an apt name because what is supposed to be fundamental on this view is the wave function, not particles. So, although the points in this space might correspond in a sense to particle configurations, what this space is fundamentally is not a space of particle configurations. Likewise, although we’ve represented the number of dimensions configuration space has as depending on the number N of particles in a system, this space’s dimensionality should not really be construed as dependent on the number of particles in a system. Nevertheless, the wave function monist need not be an eliminativist about particles. As we have seen, for example, in the Everettian approach, wave function monists can allow that there are particles, derivative entities that emerge out of the decoherent behavior of the wave function over time. Wave function monists favoring other solutions to the measurement problem can also allow that there are particles in this derivative sense. But the reason the configuration space on which the wave function is spread has the number of dimensions it does is not, in the final analysis, that there are particles. This is rather a brute fact about the wave function, and this in turn is what grounds the number of particles there are.
