It's so easy to call something out as bullshit by cherry picking the bad bits. Just because there's BS out there simply aimed at exploiting guys desperate to solve their problems doesn't mean that all the information out there is nonsense. In fact a lot of things in pua are inspired by or pulled from more legitimate fields such as social psychology, linguistics, game theory, simple health and fitness, interpersonal attraction research and so on. Much of this information is then rehashed and given "lingo" to fit the pua brand and industry image that appeals to the underground society image in order to sell it better.

Yes there's BS but plenty is good too... Although sold at ridiculously exploitative prices..
