> Meanwhile, those who consumed the drugs but thought they were taking a placebo experienced no significant increase in wellbeing. It's wild that there was a part of this study in which people were told that they weren't taking a psychadelic, but they were taking a psychadelic.
> This study used a ‘self-blinding’ citizen science initiative, where participants were given online instructions on how to incorporate placebo control into their microdosing routine without clinical supervision. The study was completed by 191 participants, making it the largest placebo-controlled trial on psychedelics to-date.
So everyone in the study presumably was interested in microdosing and, given that they would have sourced the drugs themselves, knew what they could have been taking.
Unless I’m misunderstanding. Either way, the methodology here seems really suspect to me.
