A new University of Georgia study suggests that online social networking sites such as Facebook might be useful tools for detecting whether someone is a narcissist.
"We found that people who are narcissistic use Facebook in a self-promoting way that can be identified by others," said lead author Laura Buffardi, a doctoral student in psychology who co-authored the study with associate professor W. Keith Campbell.
The researchers found that the number of Facebook friends and wallposts that individuals have on their profile pages correlates with narcissism. Buffardi said this is consistent with how narcissists behave in the real-world, with numerous yet shallow relationships. Narcissists are also more likely to choose glamorous, self-promoting pictures for their main profile photos, she said, while others are more likely to use snapshots.
