AT THE MARGINS: A DISTINCTIVENESS APPROACH TO THE SOCIAL IDENTITY AND SOCIAL NETWORKS OF UNDERREPRESENTED GROUPS AJAY MEHRA University of Cincinnati MARTIN KILDUFF DANIEL J. BRASS The Pennsylvania State University 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 minor- ity individuals' own preferences for same-race friends. By contrast, the marginaliza- tion of women resulted more from exclusionary pressures than from their preferences for woman friends. People are social beings who seek to establish ranks (Brass, 1985). A recent report, for example, ties of identity and friendship with others.
