This article proposes a new theoretical framework for the reviewed state-of-the-art research on collective narcissism-the belief that the ingroup's exceptionality is not sufficiently appreciated by others. Collective narcissism is motivated by the investment of an undermined sense of self-esteem into the belief in the ingroup's entitlement to privilege. Collective narcissism lies in the heart of populist rhetoric. The belief in ingroup's exceptionality compensates the undermined sense of self-worth, leaving collective narcissists hypervigilant to signs of threat to the ingroup's position. People endorsing the collective narcissistic belief are prone to biased perceptions of intergroup situations and to conspiratorial thinking. They retaliate to imagined provocations against the ingroup but sometimes overlook real threats. They are prejudiced and hostile. Deficits in emotional regulation, hostile attribution bias, and vindictiveness lie behind the robust link between collective narcissism and intergroup hostility. Interventions that support the regulation of negative emotions, such as experiencing self-transcendent emotions, decrease the link between collective narcissism and intergroup hostility and offer further insights into the nature of collective narcissism.

We examined whether and why collective narcissism (i.e., resentment for insufficient recognition of the in-group’s importance) versus in-group satisfaction (i.e., a belief that the in-group and one’s membership in it are reasons to be proud) have opposite, unique associations with hostility toward Syrian refugees in Poland. Results of two cross-sectional studies (Study 1, N = 1066 and Study 2, N = 419) converge to indicate that collective narcissism predicts hostility toward Syrian refugees via attributing Syrian refugees with hostile intentions toward Poles. In-group satisfaction is associated with rejection of hostile actions toward Syrian refugees because it decreases hostile attribution bias with regards to Syrian refugees. Thus, being a satisfied member of a national group promotes tolerance toward refugees, while collective narcissism is associated with blaming refugees for provoking the in-group’s hostility.

We investigated whether collective narcissism (i.e., believing that the in-group is exceptional but insufficiently recognized by others) and in-group satisfaction (i.e., believing that the in-group is a source of satisfaction) have opposite, unique associations with intergroup aggression via belief in the hedonistic function of revenge (i.e., an expectation of emotional reward from harming others in response to feeling oneself harmed). Results of two studies conducted in Poland (N = 675) found that collective narcissism is positively related to belief in the hedonistic function of revenge, whereas in-group satisfaction is negatively related, and both are related to intergroup aggression. These relationships were found only when the overlap between collective narcissism and in-group satisfaction was partialled out. The results shed a new light on the mechanisms linking in-group positivity to out-group derogation, and highlight the importance of investigating revenge motivations in the intergroup relations.
