Depatterning factor hypothesis

The Depatterning factor hypothesis proposes that psychedelic effects might sometimes loosen established patterns of perception and behavior, creating room for responses that could help a group adapt when its environment changes. Giorgio Samorini develops the idea as an evolutionary possibility, not a demonstrated mechanism: most departures from familiar behavior would fail, but a few might prove useful. The concept links animal behavior, human ecological crisis, and the social question of how powerful altered states should be contained and directed.

The evolutionary hypothesis

Samorini’s starting point is a problem of adaptation. During periods of rapid environmental change or crisis, a group’s customary responses may cease to be effective. In his account, psychedelic-induced departures from those responses could prompt some individuals to experiment with unfamiliar behavior. Most such innovations would be disadvantageous and disappear through natural selection; a small number might help the individual, the group, or even the species adjust to changed conditions.

The hypothesis takes its name from this proposed function: a depatterning factor introduces variation into behavior, much as genetic mutation introduces variation into a population. The analogy does not make the two processes identical, and the book offers no evidence that psychedelic experiences reliably produce adaptive innovations. Rather, it gives a possible evolutionary interpretation to the chance that some altered states may loosen established responses at moments when novelty matters.

The argument is deliberately tentative. The account of Samorini’s idea is described as speculative, and its force lies in opening a question rather than settling it: could an experience that disrupts ordinary perception occasionally help an organism respond to conditions for which inherited or learned patterns are inadequate? The potential value is inseparable from the risk. Departing from familiar behavior can generate possibilities, but most possibilities will not be useful.

Animals, risk, and behavioral variation

The animal examples make the hypothesis more concrete while also exposing its uncertainty. Michael Beug reports accounts of horses apparently tripping in paddocks and dogs that seek out psilocybin mushrooms and appear to hallucinate. Several nonhuman primate species are also known to eat psychedelic mushrooms. These observations suggest that consumption is not unique to humans, but they do not establish what the animals experience or whether the behavior benefits them.

At small doses, psychedelic mushrooms might increase sensory acuity or focus and thereby offer some fitness advantage. A 2015 review in the Journal of Ethnopharmacology reported that some tribes feed psychoactive plants to dogs to improve their hunting ability. At higher doses, however, intoxication would seem likely to put an animal at a survival disadvantage; the book acknowledges that many animals may suffer that cost. The depatterning hypothesis concerns the possibility that, for a few individuals, the consequences could extend beyond immediate impairment if altered behavior produced a useful response for the group.

The same evolutionary speculation reaches from animals to human beings. The book raises the possibility that Homo sapiens may face a crisis calling for mental and behavioral change, and wonders whether psychedelic molecules could contribute to such a shift. This is posed as an open question, not as proof that nature has supplied psychedelics for a human purpose. The hypothesis’s appeal depends on keeping its two sides in view: disruption can be destructive, yet an occasional break with convention might make adaptation possible.

Paul Stamets and the ecological interpretation

Paul Stamets embraces a broader, more purposeful version of the idea. During a conversation around a fire, he describes psilocybin as a chemical messenger from Earth and imagines human beings, because of their consciousness and language, as capable of hearing a call to protect the environment. He argues that plants and mushrooms have intelligence and communicate with humans biochemically, seeking support for ecological care. The book presents this as Stamets’s interpretation, not as an established scientific account of fungal intention.

Stamets also describes mushrooms as having changed his sense of personal identity. Rather than feeling confined to an individual human life, he understands himself as part of a continuing flow of molecules through nature. The narrator compares this expansive sense of belonging to the unitive consciousness reported by volunteers at Johns Hopkins: in Stamets’s case, the perceived whole is the web of nature. This experience supplies a personal and ecological dimension to depatterning. A loosening of the bounded self, in this account, may alter how a person understands their relation to the living world.

For Stamets, the ecological urgency is practical as well as spiritual. He believes psilocybin has given him insights that might help him steer and accelerate fungal evolution, so that fungi could contribute solutions before ordinary evolutionary change arrives too late. The narrator does not simply accept the scale of this claim. Stamets’s talk can seem to approach the edge of implausibility, but a tour of Fungi Perfecti provides a material counterpoint: the company’s grow rooms, research facilities, clean rooms, laminar flow chambers, tissue-culture work, and framed patents show that he is not only a speculative talker but also a working mycologist and entrepreneur. That contrast lends the ecological vision practical context without verifying its larger claims.

Disruption, guidance, and social use

The hypothesis also resonates with the book’s account of competing frameworks for psychedelic use. Psychotomimetic models treated the drugs through their resemblance to psychosis; psycholytic practice incorporated them into psychoanalysis; psychedelic therapy instead proposed a single high-dose session intended to produce a conversion-like experience. That model challenged established psychiatric routines and blurred distinctions between therapist and patient, sickness and health, and scientific practice and spirituality. The shift from one framework to another shows that psychedelic disruption was never only a question of brain effects: it also unsettled professional roles and institutions.

The book describes these frameworks as different kinds of containers for powerful substances, each combining protocols with an explanatory model. In contrast, an unguided do-it-yourself approach leaves the experience without a comparable medical, religious, or scientific structure. The author argues that other societies’ long experience with psychedelics might have taught Americans the importance of rituals, rules, and a guide, but that these traditions were often discounted. The Depatterning factor hypothesis therefore does not imply that disruption should be sought without limits. If altered states can loosen established responses, the conditions under which they are entered—and the support around them—matter.

That question persists as psychedelic therapy returns to clinical research. The Johns Hopkins and New York University cancer trials reported clinically significant reductions in anxiety and depression for about 80 percent of participants, lasting at least six months; stronger reported mystical experiences correlated with greater symptom relief. The studies did not explain why the experiences were associated with improvement, and their results do not test Samorini’s evolutionary hypothesis. They do, however, underscore the wider book’s concern with how altered states may matter beyond their immediate pharmacology. The possible value of disruption remains dependent on interpretation, context, and what follows the experience.
