Scholarship on peoples’ involvement in social movements shows that social networks predict movement participation. Research in this area has traditionally focused on connections to activists—but other kinds of social relationships, such as intergroup contact, may matter as well. In this study, unique data were collected from both a student sample and a general sample of the population to examine how intergroup contact—namely, social ties with African Americans—affects whites’ participation in the Black Lives Matter (BLM) movement. In both samples, intergroup contact is a significant predictor of participation in BLM, net of other factors. The study's findings suggest that social ties outside of activist networks can matter greatly for movement participation; they also suggest that intergroup contact can affect more than just attitudes—it can spur collective action.

动员我们的纽带：网络、群体间联系和参与 Black Lives Matter 运动

关于人们参与社会运动的学术研究表明，社会网络可以预测运动参与。该领域的研究传统上侧重于与活动家的联系——但其他类型的社会关系，例如群体间的联系，也可能很重要。在这项研究中，从学生样本和一般人口样本中收集了独特的数据，以检查群体间接触（即与非裔美国人的社会关系）如何影响白人参与“黑人的命也是命”（BLM）运动。在这两个样本中，群体间接触是参与 BLM 的重要预测因素，不包括其他因素。该研究的结果表明，激进主义网络之外的社会关系对运动参与非常重要。
