The Discerning Texan

NICE guys knew it, now two studies have confirmed it: bad boys get the most girls. The finding may help explain why a nasty suite of antisocial personality traits known as the "dark triad" persists in the human population, despite their potentially grave cultural costs.
The traits are the self-obsession of narcissism; the impulsive, thrill-seeking and callous behaviour of psychopaths; and the deceitful and exploitative nature of Machiavellianism. At their extreme, these traits would be highly detrimental for life in traditional human societies. People with these personalities risk being shunned by others and shut out of relationships, leaving them without a mate, hungry and vulnerable to predators.
But being just slightly evil could have an upside: a prolific sex life, says Peter Jonason at New Mexico State University in Las Cruces. "We have some evidence that the three traits are really the same thing and may represent a successful evolutionary strategy."
