Endorsement of metaphysical idealism mediates a link between past use of psychedelics and wellbeing

A cross-sectional internet survey of 701 people who had used classical psychedelics probed their metaphysical beliefs with a new 42-item questionnaire. Factor analysis revealed two main belief clusters: Idealism and Materialism. Idealism was linked to psychological insight from a past psychedelic experience and to average psychedelic use, and it predicted wellbeing. Mediation analyses showed an indirect path from past psychedelic use through Idealism to wellbeing, but not through non-physicalist beliefs generally or through Materialism. The findings suggest that Idealism specifically, rather than non-physicalist beliefs broadly, may mediate the association between psychedelic use and wellbeing, though causality remains unestablished.
