According to social identity theory, low self-esteem motivates group members to derogate out-groups, thus achieving positive in-group distinctiveness and boosting self-esteem. According to the Frankfurt School and status politics theorists, low self-esteem motivates collective narcissism (i.e., resentment for insufficient external recognition of the in-group's importance), which predicts out-group derogation. Empirical support for these propositions has been weak. We revisit them addressing whether (a) low self-esteem predicts out-group derogation via collective narcissism and (b) this indirect relationship is only observed after partialing out the positive overlap between collective narcissism and in-group satisfaction (i.e., belief that the in-group is of high value and a reason to be proud). Results based on cross-sectional (Study 1, N = 427) and longitudinal (Study 2, N = 853) designs indicated that self-esteem is uniquely, negatively linked to collective narcissism and uniquely, positively linked to in-group satisfaction. Results based on cross-sectional (Study 3, N = 506; Study 4, N = 1,059; Study 5, N = 471), longitudinal (Study 6, N = 410), and experimental (Study 7, N = 253) designs corroborated these inferences. Further, they revealed that the positive overlap between collective narcissism and in-group satisfaction obscures the link between self-esteem and out-group derogation.

低自尊心会通过集体自恋来预测群体外贬损，但是这种关系却被群体内的满意度所掩盖。

根据社会认同理论，低自尊感会促使群体成员贬低群体外的群体，从而实现积极的群体内独特性并增强自尊心。根据法兰克福学派和地位政治理论家的说法，自卑感会激发集体自恋（即对外部对群体内重要性的认识不足而产生的不满情绪），这预示着群体外贬损。对这些主张的经验支持很弱。我们重新审视他们的问题，即（a）低自尊心是否会通过集体自恋来预测群体贬损，以及（b）这种间接关系只有在消除了集体自恋和群体内满意度之间的积极重叠之后才能观察到（即，相信团队合作具有很高的价值，是值得骄傲的理由）。基于横截面的结果（研究1，N = 427）和纵向（研究2，N = 853）设计表明，自尊与集体自恋具有独特的负相关关系，与团体内的满意度具有独特的正相关关系。结果基于横截面（研究3，N = 506;研究4，N = 1,059;研究5，N = 471），纵向（研究6，N = 410）和实验（研究7，N = 253）设计证实了这些推论。此外，他们发现，集体自恋与群体内满意度之间的积极重叠掩盖了自尊与群体外贬损之间的联系。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。N = 506; 研究4，N = 1,059；研究5，N = 471），纵向（研究6，N = 410）和实验设计（研究7，N = 253）证实了这些推论。此外，他们发现，集体自恋与群体内满意度之间的积极重叠掩盖了自尊与群体外贬损之间的联系。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。N = 506; 研究4，N = 1,059；研究5，N = 471），纵向（研究6，N = 410）和实验设计（研究7，N = 253）证实了这些推论。此外，他们发现，集体自恋与群体内满意度之间的积极重叠掩盖了自尊与群体外贬损之间的联系。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
