Hmm...I myself have wondered the same thing. Either there is a very high number of narcissists out there, or NPD is an inaccurate label used for other abusive behavior. NPD is VERY popular in the media and even on PsychCentral. Lol, go to the homepage and you're bound to find many articles on it.

At the same time, I dated someone who I thought was NPD. He was very into himself, didnt care about me or my feelings, was VERY manipulative, lied a lot, and was very abusive. he could very well just be a terrible person though. I think people feel better diagnosing assholes with something. But I don't know the statistics of NPD and how common it really is.

Ps: I don't understand your thread title.....
