“…In their effort to maintain a positive sense of self, people with high levels of narcissism often denigrate others, and as a result experience significant dislike from those around them at longer acquaintance. Their low communal focus and high antagonism (Czarna, Czerniak, & Szmajke, 2014;Czarna, Jonason, Dufner, & Kossowska, 2016;Lamkin, Clifton, Campbell, & Miller, 2014) might be discouraging to freshly won friends. Indeed narcissism predicts initial popularity (Back, Schmukle, & Egloff, 2010;Carlson, Vazire, & Oltmanns, 2011;Dufner et al, 2012;Dufner, Rauthmann, Czarna, & Denissen, 2013;Friedman, Oltmanns, Gleason, & Turkheimer, 2006, Wurst et al, in press), but studies showing longer-term costs of narcissism rather than short-term benefits have been rare, and both longitudinal studies (Leckelt, Küfner, Nestler, & Back, 2015;Paulhus, 1998) and investigations of wider interpersonal contexts are exceptions (Clifton, 2011;Czarna, Dufner, & Clifton, 2014;Küfner, Nestler, & Back, 2013).…”
