Status characteristics and expectation states theory (SC-EST) describes how general beliefs about capability contribute to disproportionate rates of power, prestige, and resource outcomes between group members. Similarly, endorsements for competition stem from a general belief that it is useful for identifying which people are more capable and therefore more deserving of limited or highly valued resources. This paper investigates the relationship between both contexts simultaneously by considering whether introducing intergroup competition into an otherwise collectively oriented task situation essentially promotes inequality between diverse group members. Using a two-condition experiment, we demonstrate how interaction dynamics change in racially diverse task groups when their task involves intergroup competition compared to no competition. The findings support our predictions that intergroup competition promotes inequality by reproducing and exacerbating macro-level inequalities in micro-level interpersonal interactions. Specifically, white group members were significantly less likely to defer (i.e., accept others’ suggestions) when the group task involved intergroup competition. Overall, these results offer insight into the diverging effects of unequal group processes in group settings and the detrimental effects of competition.
