This paper pooled results from 19 randomized trials with 1,173 adults to see if meditation and yoga change PTSD symptoms. Overall, these mind–body practices were linked to a small-to-medium reduction in PTSD symptoms (effect size = −0.39). The authors found no big differences by type of practice, who was studied,…
In a natural, open-label study at a microdosing event, researchers tested people before and while they expected the effects of a psychedelic truffle microdose. They found better performance on a task that measures convergent thinking and on a task that measures divergent thinking. A short test of fluid intelligence did…

Overall, exposure to upward comparisons produced a small but statistically significant negative effect on self-evaluations and emotions (g = −0.24, p…

After the psilocybin session, measures…

This was a 6-week, double-blind, placebo-controlled trial that tested low-dose LSD (20 μg) given twice weekly in 53 adults with moderate to severe ADHD. Both the LSD group and the placebo group showed similar symptom reductions by week 6 (LSD mean change on the ADHD rating scale −7.1 points; placebo…

They ran three studies with a total of 1,365 English-speaking people from varied gender, sexual, and cultural backgrounds. After initial exploratory analyses, a confirmatory factor analysis supported a final 12-item scale with three…
