Men who post lots of selfies reveal more than they know

Everywhere you look these days, people are striking poses, snapping selfies on their smartphones and posting them on social media. But a new study suggests that for men, those self-portraits could be a sign of a personality disorder.

In a study conducted by Ohio State University communications professor Jesse Fox, the men who posted the most selfies to the web also showed the highest measures of psychopathy and narcissism.

Researchers studied 800 male participants between the ages of 18 and 40 who completed a survey about their social media behavior and standard questionnaires that measure anti-social behaviors and self-objectification.

Fox told Ohio State's press office it's not surprising that men who post a lot of selfies are narcissistic -- but this is the first time the association has been measured.

"The more interesting finding is that they also score higher on this other anti-social personality trait, psychopathy, and are more prone to self-objectification," Fox said.

The men's results were still within the normal range of behavior, but higher than average.
