Effects of psychedelic use on authoritarian attitudes revisited.

Across three studies—a naturalistic observation, a single-arm psilocybin trial with healthy volunteers, and a randomized controlled trial comparing psilocybin to escitalopram in depressed patients—psychedelic use did not produce significant changes in authoritarian attitudes. Contrary to earlier suggestions, the evidence does not reliably show that psychedelics decrease authoritarian attitudes. Future work should use larger, more diverse samples and examine other political outcomes.

Abstract

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. We aimed to examine the effects of psychedelic use on authoritarian attitudes. 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. Across the three studies, results showed no significant changes in authoritarian attitudes after psychedelic use. 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.
