Thank you, Yuval; I'll make an effort to read the book soon.

I'm curious as to how Pinker discusses the biological parameters in criminology, and would be happy if you could elaborate a bit about that.

Discussing "criminality" as a deterministic quality has been around for quite a while, emerging in the late 1800s in the work of Lombroso and Ferri; the idea that criminal types are "atavistic", underdeveloped humans, was advanced using craneal measurements of prisoners. Naturally, there was much to question about that "biology" (to give one example, Lombroso's relation to tattoos as biological features), but that raises the question of whether one can identify a tendency toward criminality in general, or merely limit such predictions to certain TRAITS that might relate to certain KINDS of behavior we have defined as criminal, such as predicting propensity toward violence from the presence of a third X chromosome.

Anyway, if you feel like it, I'd love to get more info.
