The Utter Phoniness of Evolutionary Psychology

It's taken a long time, but at last—thank you for contributing, Meghan!—evolutionary psychology is being revealed as the psuedoscience it usually is, at least by the time it reaches the newspaper columns and the conversations around the water cooler. My main objection has always been the way its lay adherents solemnly discuss research that confirms the existence of some utterly banal aspect of human behavior, usually sexual, and then go on to explain why our ape ancestors found it so useful. Usually, this involves self-satisfied explanations of the primal male "need" for multiple sexual partners—men "need" to spread their DNA around, you see—as opposed to the primal female "need" for a man to protect her children. But why, then, did the human race evolve the concept of monogamy? And who are these women with whom the naturally adulterous men are supposed to sleep? I know that evolutionary psychology has come up with various explanations for these phenomena, but really, one could argue the whole thing the other way around, too. It's like Marxism or Freudianism: a set of all-encompassing principles that can explain anything. And it, too, will pass.
