A Single Belief-Changing Psychedelic Experience Is Associated With Increased Attribution of Consciousness to Living and Non-living Entities

In a retrospective survey of 1,606 respondents who reported a belief-changing psychedelic experience, participants reported large increases in attributing consciousness to a broad range of living and non‑living entities (e.g. non-human primates, plants, fungi, inanimate objects), with greater increases linked to higher ratings of mystical experience and persisting for years. Beliefs in free will and superstitions did not change, and the authors recommend prospective controlled studies to rule out expectancy effects.

Abstract

Introduction

Although the topic of consciousness is both mysterious and controversial, psychedelic drugs are popularly believed to provide unique insights into the nature of consciousness despite a lack of empirical evidence.

Methods

This study addresses the question of whether psychedelics change the attribution of consciousness to a range of living and non-living entities. A survey was conducted in 1,606 respondents who endorsed a belief changing psychedelic experience.

Results

Participants rated their attributions of consciousness to a range of living and non-living entities before and after their psychedelic experience. Superstitious beliefs and belief in freewill were also assessed. From before the experience to after, there were large increases in attribution of consciousness to various entities including non-human primates (63–83%), quadrupeds (59–79%), insects (33–57%), fungi (21–56%), plants (26–61%), inanimate natural objects (8–26%), and inanimate manmade objects (3–15%). Higher ratings of mystical experience were associated with greater increases in the attribution of consciousness. Moreover, the increased attributions of consciousness did not decrease in those who completed the survey years after the psychedelic experience. In contrast to attributions of consciousness, beliefs in freewill and superstitions did not change. Notably, all findings were similar when restricted to individuals reporting on their first psychedelic experience.

Discussion

This study demonstrates that, among people who reported belief-changing psychedelic experiences, attribution of consciousness to various entities increases. Future prospective psychedelic drug administration studies that control for expectancies are needed.

Research Summary of 'A Single Belief-Changing Psychedelic Experience Is Associated With Increased Attribution of Consciousness to Living and Non-living Entities'

Introduction

The paper addresses whether a single psychedelic experience can alter how people attribute conscious awareness to other living and non-living entities. The authors situate the question within long-standing debates about the nature of consciousness and the problem of other minds, note that psychedelics produce striking changes in phenomenological experience, and cite prior work showing that psychedelic experiences can change metaphysical beliefs (for example, increased agreement with panpsychism). The introduction identifies a gap in empirical data directly linking psychedelic experiences to changes in mind‑attribution and motivates an investigation using retrospective self-report of belief change following a single psychedelic episode. This study therefore set out to measure changes in participants' beliefs about the capacity for conscious experience across a range of entities (from self and other humans through animals, plants, fungi, and inanimate objects, to the universe) before and after a psychedelic experience that the respondent judged to have produced the greatest belief change. Josipovic and colleagues aimed to test whether such attribution increases occur, whether they are related to the intensity of mystical-type experiences, and whether changes persist over time.
