Abstract

 

Although it is well-established that people tend to view themselves through rose-colored glasses, efforts to identify robust individual differences in this tendency have generally left researchers empty-handed. Narcissistic individuals have long been observed to overestimate their attributes and accomplishments, however, suggesting that narcissistic traits might be one risk factor for engaging in self-enhancing and overconfident behaviors. The goal of the present study was to investigate the link between personality and self-enhancement broadly construed. Atlanta community members (N = 138; Mage = 25 years; 62% female; 30% African American, 26% Caucasian; 19% Asian) reported on their own personality and completed a series of laboratory tasks evaluating their tendencies toward self-enhancement and overconfidence. Although many participants tended towards self-enhancement, there were substantial individual differences in this tendency. Certain features of narcissism, namely those associated with leadership and authority, were consistently positively associated with the broad swath of self-enhancement and overconfidence indicators. Other traits, such as extraversion, antagonism, disinhibition, and self-esteem were also related to self-enhancement, although less consistently. In contrast, neuroticism and internalizing symptomology were negatively associated with overconfidence and self-enhancement. Together, the current study has aided in targeting replicable personality traits implicated in self-enhancement and overconfidence, with narcissism being the most salient risk factor for viewing oneself overly positively.
