I thought y'all might enjoy THIS little piece of research, courtesy of The Week magazine 9-29-06. The highlight is mine.

"It's hardly a surprise, but a study now offers definitive proof that celebrities are the ultimate narcissists. Dr. Drew Pinsky, a physician and host of the long-running radio show Loveline, collected personality data from 200 of the celebrity guests who visited his studio, then tested them for narcissistic traits - such as the (unsupported) belief they are smarter, more talented, or more worthy than other people. Pinsky found that male celebrities were significantly more narcissistic than average people, and female celebrities were even worse. Musicians were the least self-obsessed because their rise to fame had the most to do with actual talent, whereas reality-show stars - the least talented people in the limelight - scored highest. "Female reality-show contestants are off the chart," Pinsky tells the Los Angeles Times. It's important not to confuse narcissism with egotism, or genuine self-love, Pinsky says. Narcissists actually have low self-esteem...and compensate by seeking fame."

It'd be interesting to see musicians broken down by instrument.

That's what I was thinking. I'd guess singers would be up there with Omarosa from The Apprentice, guitar players maybe at Alec Baldwin level, drummers at normal human level, and bass players would be hard to pin down since their egos often depend on their blood-alcohol level.
