The current research explores how local racial diversity affects Whites' efforts to structure their local communities to avoid incidental intergroup contact. In two experimental studies (N = 509; Studies 1a-b), we consider Whites' choices to structure a fictional, diverse city and find that Whites choose greater racial segregation around more (vs. less) self-relevant landmarks (e.g., their workplace and children's school). Specifically, the more time they expect to spend at a landmark, the more they concentrate other Whites around that landmark, thereby reducing opportunities for incidental intergroup contact. Whites also structure environments to reduce incidental intergroup contact by instituting organizational policies that disproportionately exclude non-Whites: Two large-scale archival studies (Studies 2a-b) using data from every U.S. tennis (N = 15,023) and golf (N = 10,949) facility revealed that facilities in more racially diverse communities maintain more exclusionary barriers (e.g., guest policies, monetary fees, dress codes) that shield the patrons of these historically White institutions from incidental intergroup contact. In a final experiment (N = 307; Study 3), we find that Whites' anticipated intergroup anxiety is one driver of their choices to structure environments to reduce incidental intergroup contact in more (vs. less) racially diverse communities. Our results suggest that despite increasing racial diversity, White Americans structure local environments to fuel a self-perpetuating cycle of segregation.

当前的研究探索了当地种族的多样性如何影响白人为构建当地社区而避免偶然的群体间接触的努力。在两个实验研究（Ñ= 509; 研究1a-b）中，我们考虑了白人的选择，以构建一个虚构的，多样化的城市，并发现白人在更多（相对于更少）与自我相关的地标（例如，他们的工作场所和儿童学校）周围选择了更大的种族隔离。具体而言，他们期望在地标上花费的时间越长，他们将其他白人集中在该地标周围的时间就越多，从而减少了偶然的群体间联系的机会。白人还通过建立不成比例地排除非白人的组织政策来构建环境，以减少偶然的团体间接触：两项大规模档案研究（研究2a-b）使用了来自每支美国网球（N = 15,023）和高尔夫（N= 10,949）设施表明，种族更加多元化的社区中的设施保持更多的排他性障碍（例如，宾客政策，货币费用，着装要求），使这些历史悠久的白人机构的顾客免受偶然的群体间接触。在最后的实验（N = 307；研究3）中，我们发现白人预期的群体间焦虑是他们选择结构环境以减少更多（相对于更少）种族多样化社区中偶然群体间接触的驱动力。我们的结果表明，尽管种族多样性有所增加，但美国白人仍在构建当地环境，以助长种族隔离的自我延续。
