Effects of psychedelic use on authoritarian attitudes revisited

Background: Previous research suggests that psychedelics may, under certain conditions, decrease authoritarian attitudes, but larger and more rigorously designed studies are needed to confirm these findings. Aims: We aimed to examine the effects of psychedelic use on authoritarian attitudes. Methods: Using data from three separate studies with different designs and populations, we investigated the relationship between psychedelic use and authoritarian attitudes. Study 1 was a naturalistic observational study with participants who planned to use psychedelics at their own initiative, Study 2 was a single-arm study with healthy volunteers who received psilocybin, and Study 3 was a randomized, controlled trial with patients diagnosed with depression who received psilocybin or escitalopram. Results: Across the three studies, results showed no significant changes in authoritarian attitudes after psychedelic use. Conclusions: Contrary to previous research, the latest evidence is not compelling that psychedelic use influences authoritarian attitudes in a reliable direction. Future research should recruit larger and more diverse samples, collect additional context-related data, and also investigate political outcomes other than authoritarian attitudes.
