Evolution steered humans toward pair bonding to ensure the survival of genes. But humans tend to get restless.
- Monogamy is natural, but adultery is, too, says biological anthropologist Helen Fisher.
- Even though humans are animals that form pair bonds, some humans have a predisposition for restlessness. This might come from the evolutionary development of a dual human reproductive strategy.
- This drive to fall in love and form a pair bond evolved for an ecological reason: to rear our children as a team.
Can our bodies tell the difference between recorded violence and real life danger?
- "The internet is an exciting and a dangerous place," says journalist and documentarian Sebastian Junger.
- He argues that because of thousands of years of evolution, our bodies react to seeing decapitations on screens as if they were happening in front of or to us.
- According to Junger, the internet is too new for us to really understand the long-term effects it will have on our lives.
Attractive women are especially likely to dress modestly, but only in certain scenarios.
- Psychologists have long studied male intrasexual aggression, but women's is relatively understudied.
- Past research shows that women tend to be more aggressive toward women who are attractive or who display signs of sexual permissiveness.
- The results of a new study suggest that women make strategic decisions on what to wear in order to minimize aggression from other women.
A growing body of research suggests that the "clinical pessimism" over treating psychopathy is unwarranted.
- Psychopathic individuals generally show impairments in several brain regions, a finding that's helped to promote the view that psychopathy is virtually untreatable.
- Still, there's been no concrete evidence to support this view.
- New treatments show some promising signs that psychopathy is treatable, even if it's not curable.
People who score high in "dark triad" personality traits are able to empathize. They'd just rather not.
- People who score high in the personality traits narcissism, Machiavellianism and psychopathy can empathize, but generally lack the disposition to do so, according to a recent study.
- These traits are part of the "dark triad" of personality, which has been used to study malevolent personality traits since 2002.
- The results suggest it might be possible to encourage psychopaths to empathize more, but no evidence shows this is effective over the long term.
