Résumé : The identification-prejudice link describes the defensive stance toward immigrants held by strong national identifiers. Recent research refined this relationship by suggesting that defensive national identification (operationalized through national narcissism), but not secure national identification, was associated with prejudice. While previous research found intergroup threat and conspiracy beliefs to mediate the identification-prejudice link, the need to comprehensively and experimentally test the role of these defensive group beliefs remains in the context of the narcissistic identification-prejudice link. Furthermore, following the group-based control model, we proposed that these defensive group beliefs might be more pronounced among national narcissists compensating for a low personal control. In Study 1 (N = 1104, nationally representative sample), national narcissism, but not secure national identification, was related to prejudice against immigrants, and a serial model composed of perceived intergroup threat and conspiracy beliefs mediated this relationship. These relationships held when controlling for conspiracy mentality, supporting the notion that these conspiracy beliefs were motivated at the intergroup level. In Study 2 (N = 474, pre-registered), we experimentally induced intergroup threat and exposure to conspiracy theories about immigrants. Induced threat increased conspiracy beliefs, and both increased prejudice, corroborating their causal relationship. In Study 3 (N = 350, pre-registered), we induced low personal control and made national narcissism salient to test the group-based control hypothesis. The relationship between measured (but not manipulated) national narcissism and conspiracy beliefs was more pronounced under low personal control. We discuss the role of defensive group beliefs on group-based control and prejudice against immigrants.
