An Integrated theory of false insights and beliefs under psychedelics

HT McGovern, HJ Grimmer, MK Doss… - Communications …, 2024 - nature.com
Psychedelics are recognised for their potential to re-orient beliefs. We propose a model of
how psychedelics can, in some cases, lead to false insights and thus false beliefs. We first …
