> Er, the context of this subthread is about people who already do experiment on themselves. People in the "nootropics community." There are a lot of them

They are not "experimenting" on themselves, they are simply engaging in a chemically-mediated attempt at wish fulfillment. There are few, if any, actual experimentation protocols being used and whenever I check out the scene to see if it is any better Instill find a random collection of anecdotes and poorly gathered "data points." I see no baseline data, no blinding or controls, the worst sorts of confirmation bias in data gathering and assessment, and people entering these "experiments" with a random selection of pre-exisiting conditions for which they are attempting self-medication. This is just an exercise in generating noise, not data.
