社会环境对个人的社会关系（包括种族间的友谊）产生结构性影响。在本研究中，我们假设，除了群体构成外，总语境大小对种族间友谊有明显的影响。在(i)选择朋友的偏好最大化、（ii）偏好的多维性和（iii）对同种族朋友的偏好的假设下，我们使用微观模拟进行了分析，得出了三个主要发现。首先，语境大小的增加降低了形成跨种族友谊的可能性。其次，规模效应随着偏好维度的增加而增加。第三，规模效应被噪声所稀释，即影响友谊形成的随机成分。对4745名美国高中生的实际友谊数据的分析得出了与主要结论一致的结果，即增加的背景大小促进了种族隔离，阻碍了种族间的友谊。
Social contexts exert structural effects on individuals' social relationships, including interracial friendships. In this study, we posit that, net of group composition, total context size has a distinct effect on interracial friendship. Under the assumptions of (i) maximization of preference in choosing a friend, (ii) multidimensionality of preference, and (iii) preference for same-race friends, we conducted analyses using microsimulation that yielded three main findings. First, increased context size decreases the likelihood of forming an interracial friendship. Second, the size effect increases with the number of preference dimensions. Third, the size effect is diluted by noise, i. e., the random component affecting friendship formation. Analysis of actual friendship data among 4,745 American high school students yielded results consistent with the main conclusion that increased context size promotes racial segregation and discourages interracial friendship.
