How narcissistic are you? Well, there might be an easy way to tell: How many selfies do you post? A new pair of studies stands to further solidify selfies as the de facto emblem of narcissism among the Millennial generation.
According to a study of 800 men published in the April 2015 edition of the peer-reviewed journal Personality and Individual Differences, and a not-yet-published but similar study of 400 women, people who post selfies are more likely to exhibit "the dark triad" of personality traits, reports Market Watch.
This dark triad consists of narcissism (extreme self-centeredness), Machiavellianism (manipulation of others) and psychopathy (acting impulsively with no regard for other people's feelings).
Previous research has led to similar findings. One study of 400 men and women that was published last year in the peer-reviewed academic journal Social Networking found that the more people changed their profile picture, the more likely they were to exhibit self-reported narcissistic personality traits. Also, "posting frequent status updates and sharing links with a greater frequency were specifically linked with more narcissistic tendencies in women."
However, experts point out that the research does not suggest that posting selfies makes a person more narcissistic, but rather that selfies are merely a (highly public, sometimes annoying [but they're so prevalent now that are they really annoying?]) vehicle for the already self-absorbed to blast their filtered faces out to the world. And that posting selfies occasionally doesn't make you a narcissist in the harshest sense of the term. After all, there is good narcissism (the measured kind that helps you get ahead at work) and the bad kind (which is so extreme it can harm relationships with others). But everyone tends to have a little narcissism inside of them.
So if you ever wondered which of your friends were the most narcissistic, see how many selfies they post. Although you probably don't need to look at your friends' Instagram feed to determine if they're manipulative, self-absorbed assholes. That's what Friday nights are for.
