Big Five personality and the psychedelic experience: An initial report

Journal of Psychedelic Studies November 24, 2025 Petri J. Kajonius, David Sjöström, Emma Claesdotter-Knutsson 3 citations

Most people who have had a psychedelic experience rank it among the most meaningful events in their lives, and personality traits shape how the experience unfolds. In a survey of 400 experienced users, those higher in openness reported more mystical and positive aspects, while those higher in neuroticism reported more challenging and negative aspects. The findings suggest that individual differences in personality influence both the quality and lasting impact of psychedelic experiences, and future research should measure and control for these traits.
