>in the case of Krebs and Johansen (2013, 2015), it is ~13% reporting lifetime psychedelic use, while in the ACS readers survey it is ~100%.
Just to be clear to casual readers, this wasn’t the whole ACX Readers Survey, I just only looked at the subset that filled out my psychedelic survey and seemed to have actually done psychedelics (i.e. the conclusion “all ACX readers do psychedelics” would be very incorrect). I don’t know what fraction of ACX readers have done psychedelics.
I have those for the people that put them in, but didn’t use them. If someone else was keen to do specifical analyses and explained why they’d be interesting, I’d definitely consider asking Scott for permission to share the data or trying to do the analysis myself.
