"Deceitful and despicable is one description that wronged wives could apply to their cheating husbands. Plain stupid is another. For scientists have concluded that men who sleep around are likely to have lower IQs.
Dr Satoshi Kanazawa, an evolutionary psychologist from the London School of Economics and Political Science, said the smarter a man is, the less likely he is to cheat on his partner.
His theory is based on the assertion that through evolutionary history, men have always been 'mildly polygamous'.
That has changed today, however, and Dr Kanazawa explained that entering a sexually exclusive relationship is an 'evolutionarily novel' development for them.
According to his theory, intelligent people are more likely to adopt what in evolutionary terms are new practices - to become 'more evolved'.
Therefore, in the case of fidelity, men who cannot adapt and end up succumbing to temptation and cheating are likely to be more stupid.
'The theory predicts that more intelligent men are more likely to value sexual exclusivity than less intelligent men'."
