What makes narcissists unhappy? : subjectively assessed intelligence moderates the relationship between narcissism and psychological well-being

We investigated the relations between narcissism, self-assessed intelligence and subjective well-being. In three studies, we aimed to replicate previous findings concerning the relationship between narcissism and both objectively and subjectively assessed intelligence (Study 1), as well as to examine whether the latter influenced narcissists’ satisfaction with life (Study 2) and their mood (Study 3). The results confirmed the positive link between narcissism and self-assessed intelligence. Moreover, we demonstrated that this relationship was independent of actual abilities. In line with existing literature, we also found evidence that satisfying ego needs in this domain was a necessary precondition for narcissists’ well-being. Specifically, the results of Study 2 indicated that narcissists who evaluated their intelligence as low were not satisfied with their life. Similar results were found in Study 3: narcissists evaluating their intelligence as low experienced higher tension and lower hedonic tone
