Celebrities have more narcissistic personality traits than the general population, and people with narcissistic tendencies seem to be attracted to the entertainment industry rather than the industry creating narcissists, according to a groundbreaking study conducted by researchers Drew Pinsky of the Keck School of Medicine of USC and S. Mark Young of the USC Marshall School of Business and the USC Annenberg School for Communication. The study, which will be published in the Journal of Research in Personality (Elsevier), is the first systematic, empirical scholarly study of celebrity personality and was based on a standardized test of narcissistic personality traits administered to 200 celebrities.
