Do narcissists have insight into the negative aspects of their personality and reputation? Using both clinical and subclinical measures of narcissism, the authors examined others' perceptions, self-perceptions, and meta-perceptions of narcissists across a wide range of traits for a new acquaintance and close other (Study 1), longitudinally with a group of new acquaintances (Study 2), and among coworkers (Study 3). Results bring 3 surprising conclusions about narcissists: (a) they understand that others see them less positively than they see themselves (i.e., their meta-perceptions are less biased than are their self-perceptions), (b) they have some insight into the fact that they make positive first impressions that deteriorate over time, and (c) they have insight into their narcissistic personality (e.g., they describe themselves as arrogant). These findings shed light on some of the psychological mechanisms underlying narcissism. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
