According to New Scientist, two US researches US have found that men with antisocial personality traits are more likely to have a prolific sex life.
One of the studies, a survey of 35,000 people in 57 countries, found a clear link between the so-called 'dark triad traits' and the reproductive success of males.
"It is universal across cultures for high dark triad scorers to be more active in short-term mating,'' News.com.au quoted David Schmitt, of Bradley University in the US, as saying.
"They are more likely to try and poach other people's partners for a brief affair," he added.
The second study found that males who scored higher in the dark triad personality traits had a greater number of partners and a desire for short relationships.
