I also want to say that even if PUA techniques are instrumentally successful at attracting women (I don't know if this is the case), it isn't necessarily because that the PUA worldview is epistemically correct. I'm sure anyone who sets out with the explicit goal of attracting women will be more successful at the task than they were prior to setting up that goal.

I once attended a PUA seminar, motivated by pure curiosity and interest in psychology, and there was a lot of emphasis on reading women. The basic approach could be summed up as: 1. Make yourself feel confident 2. Approach a woman, using assorted techniques 3. Determine whether she's interested 4. If she isn't, leave her alone (there was a lot of emphasis on this point) and move on to someone else as quickly as possible 5. Repeat until one bites

The techniques don't need to work on the average woman to be successful. The gauge her interest and move on quickly parts filter for those who respond well to them (I would guess also for undesirable personality traits).
