AT THE MARGINS: A DISTINCTIVENESS APPROACH TO THE SOCIAL IDENTITY AND SOCIAL NETWORKS OF UNDERREPRESENTED GROUPS.
基于独特性理论，研究显示群体在社交环境中的稀缺性会促进成员以该群体为基础建立共同身份和社交互动。相比多数群体成员，MBA项目中的少数族裔和女性更倾向于在群体内部进行身份和友谊选择，但两者的边缘化机制不同。
Using distinctiveness theory, this research showed that the relative rarity of a group in a social context tended to promote members' use of that group as a basis for shared identity and social interaction. Relative to majority group members, racial minorities and women in a master of business administration cohort were more likely to make identity and friendship choices within-group. The marginalization of racial minorities in the friendship network resulted both from exclusionary pressures and from minority individuals' own preferences for same-race friends. By contrast, the marginalization of women resulted more from exclusionary pressures than from their preferences for woman friends.
