The study found that those who scored higher on the dark triad personality traits tended to have more partners and more desire for short-term relationships, Jonason reported at the Human Behavior and Evolution Society meeting in Kyoto, Japan, earlier this month. But the correlation only held in males....
This observation seems to hold across cultures. David Schmitt of Bradley University in Peoria, Illinois, presented preliminary results at the same meeting from a survey of more than 35,000 people in 57 countries. He found a similar link between the dark triad and reproductive success in men. "It is universal across cultures for high dark triad scorers to be more active in short-term mating," Schmitt says. "They are more likely to try and poach other people's partners for a brief affair."
Now, I do have to give my own little counter theory to this as well: I think that in a lot of cases, when studying things of this nature, you're going to get a lot more of the people with 'dark triad personality traits' that will both more easily admit to having sex where some may not and will often times exaggerate the numbers for the sake of ego.
However, given the broadness of the study and the number of people they used for a test pool, does my counter theory still hold up? What do you think the reality is of the situation, based on your own experiences in life?
