What motivates a person to participate in collective action in the interest of others? From the Civil Rights Movement’s fight for ra‐ cial and economic justice, to the Stonewall uprising that demanded an equal place in society for members of the LGBTQ+ community, to the Women’s March that advocated for human rights legislation, recent history is peppered with examples of how people from mar‐ ginalized groups stood together in the face of injustice to effect change. People’s social identities, and the discriminatory experi‐ ences thereof, were a potent catalyst for involvement in collective action. But as we look at historic photos taken on the days of these marches, listen to testimonials of protesters, and read stories about important friendships that contributed to such social movements, it is clear that not all those who participate in collective action are members of the targeted groups such action seeks to correct. Drawing together research from several social psychological perspectives on intergroup relations, the Social Identity Model of Collective Action (SIMCA, van Zomeren et al., 2008) identified crit‐ ical factors that drive participation in collective action. Specifically, people who are members of a group facing individual and structural disadvantages (i.e., group identification) and those who are aware that such disadvantages exist relative to other groups (i.e., per‐ ceived injustice) are more likely to be involved in collective action.1 And, indeed, marginalized group members (e.g., racial/ethnic mi‐ nority individuals) are often at the heart of collective action, as seen in the aforementioned anecdotes and supported by empirical evidence. Yet, marginalized group members cannot, and should not, be expected to combat discrimination alone. People from

学生友谊网络的种族组成预测了对不公正和参与集体行动的看法

是什么促使一个人为了他人的利益而参与集体行动？从民权运动争取种族和经济正义的斗争，到要求LGBTQ +社区成员在社会上享有平等地位的斯通沃尔起义，再到倡导人权立法的妇女游行，最近的历史充斥着以下例子：边缘化群体的人们如何面对不公正而影响变革的立场。人们的社会身份及其歧视性经验是参与集体行动的有力催化剂。但是，当我们看这些游行那天拍摄的历史照片，听取抗议者的推荐书并阅读有关促成这种社会运动的重要友谊的故事时，显然，并非所有参与集体行动的人都是该行动力图纠正的目标群体的成员。集体行动的社会认同模型（SIMCA，van Zomeren等，2008）从几种社会心理学角度对群体间关系进行了研究，确定了促使人们参与集体行动的关键因素。具体而言，属于某个群体的成员面临个人和结构上的不利因素（即，群体认同），并且意识到与其他群体相比存在这种不利因素（即，认为不公正）的人们更有可能参与集体行动.1实际上，边缘化群体成员（例如种族/族裔个体）通常是集体行动的核心，如上述轶事所示，并得到了经验证据的支持。但是，不能也不应期望边缘化群体成员单独与歧视作斗争。来自的人
