Regarding PUA and evolutionary psychology: I don't see how a self-selected population that's under the influence of alcohol, and has been living with all kinds of weird modern norms and technology, has all that much in common with the EEA.

Good point that I hadn't thought of. And also, most mating in the EEA would be with people that you'd had and expect to have extended interactions with-- this is probably very different from trying to pick up strangers.
