A recent study showed that social networks raise the level of the so called narcissism of the American youth. It also showed that American youth uses Instagram more than Facebook.

Though Facebook is still the most popular social network site, more than half of its American users are aged 65 and older. What does this shift in social media preference say about the psychology of its users?

Around 70 percent of the American people check their Facebook site daily, Medicaldaily.com reports, citing The Week. However, 53 percent of young Americans are now choosing to share their photos over Instagram.

A separate study found that although age does seem to be involved with the decision to use Facebook or Instagram, activity level was more closely dictated by the user's level of narcissism. Researchers asked social media users to complete a Narcissistic Personality Inventory as well as record how often they tweeted and/or updated their Facebook status during the routine day. The results showed that narcissism was the “primary driver” for these social media updates. Interestingly, this narcissistic motivation was more closely observed in Twitter users than Facebook users.

However, specialists say, narcissism is not a bad thing. Created by social media, it has caused young people to become more self-aware, and in time more likely to go after something they desire.

It should be noted that other social media networks, like LinkedIn or Pinterest, aren't doing too badly.
