Meaning, Identity, and Belief

Psychedelic experiences frequently produce lasting shifts in self-concept, metaphysical beliefs, and sense of meaning, a phenomenon documented in surveys by Johns Hopkins, Imperial College London, and others. Common changes include increased openness (a Big Five trait), reduced fear of death, shifts from materialist to non-materialist worldviews, and revised personal narratives. This pillar examines how these shifts happen, when they persist, and the philosophical questions they raise.
