People who say their cheating spouses are stupid may be close to the mark.
Scientists have concluded that men and women who sleep around are likely to have lower IQ's.
The smarter a human is, the less likely he is to cheat on his partner, according to Dr Satoshi Kanazawa, an evolutionary pyschologist from London.
His theory is that through evolutionary history, humans have always being midly polygamous.
Today, however, entering a sexually exclusive relationship is an "evolutionary novel" development and according to his theory, intelligent people are more likely to adopt new practices, to become "more evolved"
He says humans who cannot adapt and end up succumbing to temptation and cheating are likely to be more stupid.
So there.
