title: Narcissists of a Feather Flock Together: Narcissism and the Similarity of Friends.
abstract: Who is willing to expose himself or herself to narcissists on a long-term basis? Studies that address the interactions of narcissists focus mainly on their interactions with strangers. Hence, the aim of the present study was to investigate the extent to which two best friends' similarity in narcissism would influence their similarities in other personality profiles. A total of 290 best friends' dyads filled out measurements of the whole Dark Triad as well as the Big Five. For each personality domain, profile similarity and its dependence on the similarity in the Dark Triad were determined. Results showed that the friends' similarity in narcissism significantly predicted similarity in all Big Five domains. For the general Big Five similarity as well as extraversion, the effect of narcissism similarity was stronger for male than female or mixed friends. Similarity in psychopathy and Machiavellianism significantly predicted all domains except for openness and extraversion, respectively.
