Psilocybin may reduce how strongly a patient’s own viewpoint interferes with considering someone else’s, according to a new pilot randomized study. But whether that makes patients “less egocentric” depends on distinguishing a measurable cognitive bias from a broader personality trait.
Researchers studied adults with severe alcohol use disorder and persistent depressive symptoms after detoxification. Three weeks after treatment, participants receiving higher-dose psilocybin showed reduced self-perspective interference on a computerized task. The September 2026 preprint has not undergone peer review.
Egocentric Bias Is A Cognitive Process
In everyday language, egocentricity often suggests selfishness or disregard for others. In this study, it described something narrower: difficulty setting aside what you see when determining what another person can see.
Someone can care deeply about others and still experience this interference. Reducing it does not automatically establish greater empathy, generosity, or emotional understanding.
The question is therefore whether psilocybin helps patients become less constrained by their own perspective. That possibility could matter in alcohol recovery, where social difficulties can complicate relationships and support.
Why Perspective Matters In Alcohol Recovery
Detoxification addresses withdrawal, while subsequent treatment supports relapse prevention and psychological recovery. However, difficulties processing other people’s perspectives may remain after alcohol cessation.
Earlier research has also raised interest in psilocybin-assisted treatment for alcohol use disorder. A 2022 randomized trial involving 93 participants found fewer heavy drinking days with psilocybin plus psychotherapy than with active placebo plus psychotherapy over 32 weeks. That finding supports investigating treatment mechanisms, but does not establish that reduced egocentric bias explains improved drinking outcomes. jamanetwork.com
Testing Psilocybin And Egocentric Bias
The new analysis came from the Psilocybin Alcohol Depression trial at CHU Nîmes in France. Thirty adults with severe alcohol use disorder and clinically significant depressive symptoms were enrolled after detoxification.
Participants received either 25 milligrams or a low-dose comparator of 1 milligram of psilocybin. Both groups participated in a structured therapeutic framework involving preparation, supervised dosing, and integration.
Twenty-five completed perspective-taking assessments before treatment and three weeks afterward. Excluding one participant whose performance was at chance level left 24 for analysis: 18 in the higher-dose group and six in the lower-dose group.
Testing after three weeks allowed researchers to examine changes beyond the immediate psychedelic experience.
When Your View Conflicts With Someone Else’s
The computerized task displayed an avatar in a room containing objects. Participants judged either how many objects they could see or how many the avatar could see.
Sometimes, those viewpoints matched. Sometimes, they differed.
Researchers measured the extra response time required when participants’ own view conflicted with the avatar’s. This captured egocentric interference. They also measured the reverse effect: interference from the avatar’s viewpoint when judging their own.
Separating these effects helped identify whether treatment changed the dominance of self-perspective specifically.
A Selective Reduction In Self-Perspective Interference
The higher-dose group showed a greater reduction in reaction-time egocentric bias than the lower-dose group. A second measure of self-perspective dominance also improved more with the higher dose.
However, accuracy did not show significant treatment effects. Interference from the avatar’s perspective when judging one’s own view also remained unchanged.
The results suggest that participants became less slowed by their own perspective when evaluating another viewpoint. They do not demonstrate a general improvement in social cognition or increased sensitivity to others.
How Psilocybin Might Loosen A Dominant Viewpoint
The authors interpret the findings through theories proposing that psychedelics reduce the influence of established self-related assumptions.
If one’s own perspective carries less automatic weight, alternative information may become easier to process. Psychotherapy could potentially help sustain that flexibility after dosing.
This remains a proposed explanation. The study did not measure brain activity or demonstrate how the cognitive change occurred. It also cannot isolate the contribution of psilocybin from its interaction with psychological support.
A Qualified Answer With A Clear Next Step
Does psilocybin make patients less egocentric? This study suggests it may reduce one specific form of egocentric interference in a narrowly defined patient group.
It does not show that patients became less selfish or that their relationships improved. Small, uneven groups and limited follow-up also leave the reliability and durability of the effect uncertain.
Larger studies should test whether reduced self-perspective interference translates into better everyday interactions or sustained recovery. Until then, the finding offers a candidate mechanism rather than a demonstrated personality change.
