In a 2006 study, Mark Young and Drew Pinsky administered the Narcissistic Personality Inventory (NPI) to 200 celebrities. They found that celebrities scored significantly higher on the NPI than both the general population and a comparison group of MBA students. They also found that female celebrities scored significantly higher than male celebrities, which is the opposite pattern found in the general population. Further, reality television celebrities produced the highest NPI scores, followed by comedians, actors, and musicians. Interestingly, they found no correlation between NPI scores and years of experience in the entertainment industry. This suggests that the celebrities’ narcissistic tendencies may have predated their entrance into the industry.
