A metatheoretical framework of diversity in teams

In the last 22 years, research on diversity in teams has been propelled by information processing and social categorization theories, and more recently, by theories of disparity/(in)justice and access to external networks. These theories stress different diversity processes, treating team diversity respectively as variety of information, as separation, as disparity, and as variety of access. We appraise this literature by identifying major problems in the way these four foundational theories are used either alone or in combination, arguing that the related theoretical models are inherently incomplete and static. In an attempt to resolve these problems, we introduce a metatheoretical framework that relates these four foundational theories according to the metadimensions of group boundary and diversity mindset. We also propose a metatheoretical model that identifies interactions among the four diversity processes and specifies diversity response patterns to team success or failure over time. Our metatheoretical approach resolves significant omissions in the literature and penetrates into the dynamic nature of team diversity in more complex, temporally sensitive and synthetic ways.
