Relatively self explanatory. Bad boys get more girls
Jonason and his colleagues subjected 200 college students to personality tests designed to rank them for each of the dark triad traits. They also asked about their attitudes to sexual relationships and about their sex lives, including how many partners they'd had and whether they were seeking brief affairs.
“High 'dark triad' scorers are more likely to try to poach other people's partners for a brief affair”
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.
Human nature sucks. Go robots! I suppose this is the epitome of the question: why do bad things happen to good people?
Because being good wouldn't be a virtue if it was rewarded. At the same time, religion requires us to rationalize injustice in the world by assuming that people get their just desserts in the afterlife or their next life. What bs.
