I occasionally read sociobiological or evolutionary psychological scholarship. I find it regularly thought-provoking, and also regularly a little too quick to draw grand conclusions from samples, but I had no idea that there was [so much contention around the fields]. Horgan’s recent piece for _Scientific American_ captures some of the contention, but the contention actually plays out in the comments. Fascinating! I read Chagnon long ago, while in graduate school. Reading that Pinker’s work, and others’, owes a debt to Chagnon put a couple of pieces of my own intellectual history together for me.
