Of course, one of the issues with estimating the effects of pickup knowledge is that none of this is placebo tested. Since PU itself teaches that self-confidence is crucial having a method for meeting women that you believe works should by itself produce positive results- especially for people who were previously too anxious to walk up to a stranger and say hello.

Also, those correlates your reporting are pretty general and 101-level. I'd be a little more suspicious of the efficacy of the more 'advanced' routines and techniques in the PUA literature.

(Though as usual I pretty much agree with you)
