          Your microdose was too small. I don't know what the correct dose is for you but there's a wide range between imperceptible and hallucinogenic that gives noticeable effects on mood. You should have experimented to find the correct dose before doing the experiment.

          And yet, lack of sequential dose-finding experimental design somehow doesn't stop almost all microdosers from immediately reporting wide-ranging benefits from unmeasured & variable doses nor are there any priors for knife-edge dose-response curves like suggested.

          So based on nothing you decide it's all bunk because your own experiment was bunk. I'm all for reporting negative results and I like the way you did your experiment but now you're just pulling conclusions out of your ass. You're no better than them.

          And what should we call pulling out post hoc excuses to save the appearances like 'oh you just didn't use the right dose'?

          Save appearance? I'm just calling you out on your hypocrisy. You identified a dosage (guesstimated to around 8 ug or so) that had no measurable effect on you. You identified another dosage (150 ug or so) that had a strong effect on you.

          Which are supposed to be about different things. Having no effect is exactly what the standard model 'LSD just makes you hallucinate' predicts. It's *not* what microdosers predict, who claim entirely different regime of effects in the sub-perceptual area.

          I had never read the modus tollens/ponen piece before. It was really interesting

          I don't think I linked anything about that... Are you referring to http://www.gwern.net/Prediction-markets#modus-tollens-vs-modus-ponens … or something else?

          No, you didn’t. It was linked to in the article about mathematical mistakes.

          loved reading through the LSD u-dosing post, solid work! I'd love to replicate but I know I'd be hard-pressed to follow through and execute it, so glad I can leech some info from you ^^
