Geeks who attend Comic Con, dress up as superheroes or play a lot of video games are likely to have an “elevated grandiose” level of narcissism, a University of Georgia study shows.

The school’s shrinks examined the personalities of people obsessed with geek culture and created a “Geek Culture Engagement Scale” and a “Geek Identity Scale” to measure the results.

People who scored high on both scales were far more likely to be narcissists, they found.

Subjects were scored on a scale of one to five, depending on how often they played Dungeons and Dragons, participated in role playing games, dressed up in fantasy costumes — and how much they liked things like robotics, video games and movies like “Star Wars.”

“Geek culture is a subculture of enthusiasts that is traditionally associated with obscure media like Japanese animation, science fictions and video games,” wrote researcher Jessica McCain.

“However, geek culture is becoming increasingly mainstream. In the past year alone, New York Comic Con, one of the premier geek conventions in the United States, attracted over 130,000 attendees,” she wrote.
