Facebook's 'dark side': study finds link to socially aggressive narcissism | Technology | guardian.co.uk: Researchers have established a direct link between the number of friends you have on Facebook and the degree to which you are a "socially disruptive" narcissist, confirming the conclusions of many social media sceptics.
People who score highly on the Narcissistic Personality Inventory questionnaire had more friends on Facebook, tagged themselves more often and updated their newsfeeds more regularly.
The research comes amid increasing evidence that young people are becoming increasingly narcissistic, and obsessed with self-image and shallow friendships.
