It's not even clear that those psychological factors are universal across human history, since we only really know much about a few thousand years of it.

Unfortunately you are mistaken about that. The PD is a fundamental feature of evolution. It is ubiquitous in biology. See:
But also, those articles aren't about facts, they're about books. Books that make an argument, maybe even a compelling one, but still just an argument. There's plenty of stuff in both those wikipedia articles about the rough edges around the ideas they present. In so far as they "prove" anything they only prove that these things are descriptive of the reality we perceive -- it takes a lot more to prove universality than mere observations of the nearby world.
I linked to the articles out of convenience. I could just as easily have linked to the Amazon listings for the books.

Maybe you should actually read them before you start pontificating about what they do and do not prove.
