Variety, Dissimilarity, and Status Centrality in MBA Networks: Is the Minority or the Majority More Likely to Network Across Diversity?

Abstract

The value of the networks that MBA students develop is often limited by the tendency of people to favor connections with similar others, resulting in self-segregation among identity groups. To identify the origins of network diversity, a key question for theory and practice is whether majority or minority groups are more likely to develop diverse personal networks. We provide a partial answer to this question by integrating network theory with three conceptual dimensions of diversity: variety, dissimilarity, and status. This conceptualization suggests that individuals can display three distinct types of diversity in their networks with different theoretical antecedents and outcomes. Consistent with theoretical predictions, we find systematic differences between the networks of high-status majorities and low-status minorities in a longitudinal study of MBA student networks. Specifically, minorities show more variety, greater dissimilarity, and lower status centrality in their networks compared to majorities. Tie strength and time period affect the findings in predictable ways. These results demonstrate the value of integrating diversity theory with network theory for understanding the development of inclusive networks in business schools. We conclude by discussing potential remedies to enhance the diversity of MBA student networks.
