Researchers are studying the effects of hallucinogen psilocybin, the active ingredient found in “magic mushrooms” in people. They have observed that a single dose of the drug resulted in a positive personality change in nearly 60 percent of patients 51 participants. These changes were observed in some cases to be measurably and permanently increase “openness” personality traits.
The Johns Hopkins University School of Medicine professor and study leader, Roland R. Griffiths, defined these personality changes to be increase “openness,” which includes traits related to imagination, aesthetics, feelings, abstract ideas and general broad-mindedness. Personality alterations were measured on a widely used and scientifically validated personality inventory. The participants who received the “magic mushroom” derivative were observed to have larger changes typically than healthy adults over decades of life experiences.
The results are interesting because usually adults over the age of 30 years old do not undergo personality changes. Personality is considered a stable characteristic of the psychology of people, relatively immutable and stable. But in this case, some adults did experience personality changes, suggesting that psilocybin changes one or more domains of personality.
It is important to mention that the study was conducted under controlled environments. Some study participants reported strong fear or anxiety during their daylong psilocybin sessions. In a less-supervised setting, these fears and anxiety responses could lead to harmful behavior. Thus mimicking this study in a private setting could be dangerous.
