We review the new and growing body of work on power in teams and use this review to develop an emergent theory of how power impacts team outcomes. Our paper offers three primary contributions. First, our review highlights potentially incorrect assumptions that have arisen around the topic of power in teams and documents the areas and findings that appear more robust concerning the effects of power in teams. Second, we contrast the findings of this review with what is known about the effects of power on individuals, and we highlight the directionally oppositional effects of power that emerge across different levels of analysis. Third, we integrate findings across levels of analysis into an emergent theory which explains why and when the benefits of power for individuals may paradoxically explain the potentially negative effects of power on team outcomes. We elaborate on how individual social comparisons within teams where at least one member has power increase intra-team power sensitivity, which we define as a state in which team members are excessively perceptive of, affected by, and responsive to resources. We theorize that when power-sensitized teams experience resource threats (either stemming from external threats or personal threats within the team), these threats will ignite internal power sensitivities and set into play performance-detracting intra-team power struggles. This conflict account of power in teams integrates and organizes past findings in this area to explain why and when power negatively affects team-level outcomes, and opens the door for future research to better understand why and when power may benefit team outcomes when power’s dark side for teams is removed.
