“‘Cause We Are the Champions of the World”

Abstract. National narcissism is a defensive form of group identity that is contingent on external validation and involves unrealistic belief in the nation’s greatness. Those high in national narcissism are susceptible to ingroup-enhancing narratives. In two pre-registered studies, conducted in Poland ( N = 1,134) and the United Kingdom ( N = 501), we hypothesized and found that national narcissism predicts support for historical policies that emphasize the great achievements and past dominance of one’s own group. Furthermore, we found that the relationship between national narcissism and support for ingroup-enhancing historical policies can be accounted for by the perceived contribution of one’s own country to the world’s history. We discuss implications for research on collective narcissism and historical policies.
