We examined how racial-ethnic identity centrality, or the importance of race/ethnicity in people's self-perceptions, affected peoples’ support for the Democratic and Republican candidates in the 2020 US election. We explored this association by examining the mediating role of trust in important social institutions. In Study 1, we examined these effects by comparing the pattern of relationships among people of color (POC) and white people, using a sample of 177 Amazon Mechanical Turk (MTurk) participants. In Study 2, we expanded our focus on different racial-ethnic groups, by comparing effects for Black, Latinx, Asian American/Pacific Islander (AAPI), and white participants, using a sample of 530 MTurk workers. Although there were a few findings that ran contrary to our expectations, the two studies generally found that trust in institutions that challenge the status quo, such as the media, explained the relationship between identity centrality and support for candidates among POC, especially Black and Latinx participants. We also found that trust in institutions that uphold the status quo, such as police and courts, explained the relationship between racial-ethnic identity centrality and support for candidates among white people.

信任与磨难：2020 年美国总统大选中的种族身份中心性、制度信任和对候选人的支持

我们研究了种族-民族身份的中心性，或种族/民族在人们自我认知中的重要性，如何影响人们在 2020 年美国大选中对民主党和共和党候选人的支持。我们通过研究信任在重要社会机构中的中介作用来探索这种关联。在研究 1 中，我们使用 177 名亚马逊机械土耳其人 (MTurk) 参与者的样本，比较有色人种 (POC) 和白人之间的关系模式来检验这些影响。在研究 2 中，我们通过使用 530 名 MTurk 工人的样本比较黑人、拉丁裔、亚裔美国人/太平洋岛民 (AAPI) 和白人参与者的影响，扩大了对不同种族族裔群体的关注。尽管有一些发现与我们的预期相反，这两项研究普遍发现，对挑战现状的机构（如媒体）的信任解释了身份中心性与 POC 候选人支持之间的关系，尤其是黑人和拉丁裔参与者。我们还发现，对维持现状的机构（例如警察和法院）的信任解释了种族-民族身份中心性与白人候选人支持之间的关系。
