The researchers conducted a systematic review and meta-analysis of the existing literature on the effects of psychedelics on cognition in healthy people. They identified 11 studies that met their criteria, which included studies that used a variety of psychedelics, including psilocybin, LSD, and ayahuasca.
The researchers found that psychedelics had a significant effect on cognitive performance, with an overall effect size of 0.41. This effect size is considered to be moderate but suggests that psychedelics could improve cognitive performance in healthy people.
The researchers also found that the effects of psychedelics on cognition were more pronounced in studies that used higher doses of psychedelics.
The study’s authors note that their findings should be interpreted with caution, as the studies included in the review were limited in scope and the effects of psychedelics on cognition in healthy people are still not fully understood.
They conclude that further research is needed to better understand the effects of psychedelics on cognition in healthy people.
