Smart men don't cheat

You know how you thought Jude Law was really stupid to cheat on Sienna Miller? Turns out, he really was - new research suggests men who are unfaithful are less intelligent than their loyal counterparts. Dr Satoshi Kanazawa, a researcher at the London School of Economics and Political Sciences, claims that the more intelligent a man is, the less likely it is he'll be unfaithful. His premise is that as men evolve, they become smarter and less selfish.
