On days when people take a very small, non-hallucinogenic dose of a psychedelic (microdose), and on the following day, they report feeling more authentic—more true to themselves in the moment. Over one month, 18 microdosers in the Netherlands provided 192 daily self-reports. On microdosing days, both the number of activities people engaged in and their satisfaction with those activities increased; on the next day, only the number of activities remained higher. Greater activity number and satisfaction were each linked to higher state authenticity. The authors suggest that authentic feeling and behavior may help explain the improved health and well-being previously linked to microdosing.

Microdosing—taking repeated sub-threshold doses of serotonergic hallucinogens—was expected to increase emotional diversity (emodiversity), but the opposite occurred. Over 28 days, 18 experienced microdosers reported their emotions five times daily via experience-sampling. On microdosing days, positive and overall emodiversity were significantly lower, with participants feeling more awe, shame, and less joy. Cumulative microdosing showed no effect on any emodiversity measure. The findings suggest microdosing may heighten the centrality of specific emotions, thereby reducing emotional balance.

Microdosing psychedelics—taking amounts too small to alter perception—is often reported to boost cognitive performance, but a remote testing study of 17 participants using a neurocognitive battery found no significant improvement or decline in processing speed, sustained attention, inhibitory control, set shifting, working memory, visual memory, or verbal memory on microdosing days or the day after. The results suggest that any perceived enhancement may stem from psychological rather than neurocognitive effects. Remote cognitive testing could facilitate larger, cross-cultural studies by easing participant burden.
