[Bad boys, it seems, really do get all the girls. Women might claim they want caring, thoughtful types but scientists have discovered what they really want – self-obsessed, lying psychopaths.
A study has found that men with the "dark triad" of traits – narcissism, thrill- seeking and deceitfulness – are likely to have a larger number of sexual affairs.
Peter Jonason, of New Mexico University in Las Cruces, believes that these traits may have an innate, genetic component that explains why some men seem unable to stop themselves behaving badly.
The dark triad of traits are the self-obsession of narcissism, the impulsive, thrill-seeking and callous behaviour of psychopaths and the deceitful and exploitative nature of Machiavellianism. "We have some evidence these traits may represent a successful evolutionary strategy," Dr Jonason told New Scientist magazine.]
