That popularity-difference figures prominently in the narcissism literature. But why are agentic narcissists less popular? We propose a novel answer―the tit-for-tat hypothesis. It states that agentic narcissists like other people less than non-narcissists do and that others reciprocate by liking agentic narcissists less in return. We also examine whether the tit-for-tat hypothesis generalizes to communal narcissism. A large round-robin study (N = 474) assessed agentic and communal narcissism (Wave 1) and included two round-robin waves (Waves 2-3). The round-robin waves assessed participants’ liking for all round-robin group members (2,488 informant-reports). The tit-for-tat hypothesis applied to agentic narcissists. It also applied to communal narcissists, albeit in a different way. Compared with non-narcissists, communal narcissists liked other people more and―in return―those others liked communal narcissists more. Our results elaborate on and qualify the thriving literature on narcissists’ popularity.enggrandiose narcissismagentic narcissismcommunal narcissisminterpersonal likingsocial relations model150articleurn:nbn:de:bvb:473-irb-587142
