This just in: Celebrities are more narcissistic than average. (LAT subscription required.) I know, seems kind of obvious.
Still, one interesting tidbit in the article is that musicians were found to be the least narcissistic group.
I actually would have predicted this, since we musician types spend an inordinate amount of time alone in a room engaging in strange, interminable, highly repetitive rituals involving scales and metronomes.
Naturally, this humble activity makes us extraordinary people, and thus vastly superior to other celebrities.
