This commentary critically examines the interpretation and analytic choices in Goodwin and colleagues’ recent analysis of therapeutic alliance in psilocybin treatment for treatment-resistant depression. While the authors conclude that alliance did not meaningfully contribute to treatment efficacy, we argue that this interpretation is not supported by the reported results, which are, in...

Despite their acutely inebriating and sometimes unpleasant effects, some people report positive changes in life satisfaction, well-being, or mental health after taking psychedelic drugs. One explanation may be the ability of psychedelics to trigger mystical-type experiences.
