“…The popularity of this approach is due to its connection with functional leadership theory, which states that leaders should provide teams with structural components (e.g., task roles) to improve team performance (Hackman, 2002). Assigning members different roles for performing a team task offers a new basis for differentiation, lowering previous subgroup salience and intergroup bias (Bettencourt, Molix, Talley, & Eubanks, 2007). By crosscutting task roles, social categorization becomes more complex, more possibilities for subgroup identification are created, and the distinction between in-subgroup and out-subgroup decreases, and therefore completely homogeneous subgroups, clear subgroup boundaries, and their corresponding biases are less likely to occur (Marcus-Newhall, Miller, Holtz, & Brewer, 1993).…”
