Facebook profiles can tell you more than just peoples' birthdays and what movies they like - they can reveal the self-adoring, a new study suggests. Researchers at the University of Georgia gave personality questionnaires to nearly 130 Facebook users and analyzed the content of their online profiles. They also had untrained observers look at the profiles and rate how narcissistic, or excessively egotistical, the owners of the profiles were. Facebook users were also more likely to have glamorous, self-promoting pictures for their main profile photo, while others tended to use snapshots, the study found. The untrained observers also noted the differences in photos and amount of social interaction. "We found that people who are narcissistic use Facebook in a self-promoting way that can be identified by others," Buffardi said.
