Excessive selfies by men could be a red flag for anti-social behavior, according to a study.
It is the first study of its kind published in the journal Personality and Individual Differences.
Researchers focused on men who posted more online photos of themselves than average. Those men displayed traits of narcissism and psychopathy, the study said.
This does not mean men who post a lot of selfies are necessarily narcissists or psychopaths, just that those men have higher than average levels of such anti-social traits.
