To elucidate how ingroup identification is implicated in attitudes towards gender equality, it is important to consider that (1) people simultaneously identify with more (a nation) vs. less abstract groups (gender), and (2) gender collective narcissism is the specific aspect of ingroup identification likely to inspire opposite attitudes towards gender equality among men (negative) and women (positive), but (3) national narcissism is likely to align with men’s interests and inspire negative attitudes towards gender equality among men and women. In Study 1, we demonstrate that gender collective narcissism is the same variable among men and women. In Study 2, we show that among women (but not among men) in Poland, gender collective narcissism predicts intentions to engage in normative and non-normative collective action for gender equality. In Study 3, we show that gender collective narcissists among women endorse an egalitarian outlook, whereas gender collective narcissists among men reject it. In contrast, national narcissism predicts refusal to engage in collective action for gender equality and endorsement of an anti-egalitarian outlook among women and among men. Thus, national narcissism and gender collective narcissism among men impair pursuit of gender equality. Gender collective narcissism among women facilitates engagement in collective action for gender equality. Low gender collective narcissism among men and low national narcissism may also facilitate support for gender equality.

为了阐明内部群体认同如何与性别平等态度相关，重要的是要考虑到（1）人们同时认同更多（国家）和不那么抽象的群体（性别），（2）性别集体自恋是具体的内群体认同的一个方面可能会激发男性（消极）和女性（积极）对性别平等的相反态度，但是（3）民族自恋可能会与男性的利益一致，并激发男性和女性对性别平等的消极态度。在研究 1 中，我们证明性别集体自恋在男性和女性中是相同的变量。在研究 2 中，我们表明，在波兰女性（而非男性）中，性别集体自恋预示着参与规范和非规范集体行动以实现性别平等的意图。在研究3中，我们表明，女性中的性别集体自恋者认可平等主义观点，而男性中的性别集体自恋者则拒绝这种观点。相比之下，民族自恋预示着拒绝参与性别平等的集体行动，并支持女性和男性的反平等主义观点。因此，男性的民族自恋和性别集体自恋损害了对性别平等的追求。妇女的性别集体自恋有助于参与促进性别平等的集体行动。男性中较低的性别集体自恋和较低的民族自恋也可能促进对性别平等的支持。
