Title: Power and Prosociality: Reputational Concern drives Prosociality among the Powerless
Abstract: Asymmetries in power permeate social life, relationships, and groups. Scholars have long investigated the role of power in shaping human prosociality but have collated mixed evidence as to when and how power affects cooperation. Synthesizing the evolutionary psychological literature on reputation-based cooperation with the social psychological literature on power, I contend that reputational concerns may play a crucial role in shaping the effect of power on prosociality. Consistent with this perspective, results from correlational and experimental studies (14 studies, total N = 3,121), including a mini meta-analysis, demonstrate that the powerless experience increased reputational concerns and, subsequently, display more cooperation when interacting with high-power others. Conversely, power and reputational concerns did not influence prosociality among the powerful.
Moreover, results indicate that individuals are more cooperative towards higher power in-group members than lower power in-group members. This power-based within-group discrimination was explained by the differing levels of reputational concerns felt by individuals. While previous studies on power predominantly focused on the powerful, this reputational account of power offers a new perspective that may help us better understand the psychology of the powerless.
The Speaker: Dr Hiro Imada (Research Fellow, Kochi University of Technology) conducts research on the role of reputation in social behaviour. More specifically, his research interests include reputation-based cooperation, gossip, power, and intergroup behaviour (e.g., intergroup cooperation and conflict). In his PhD thesis, he investigated how power asymmetries shape within-group and intergroup cooperation via reputational concerns. His work is grounded in social and evolutionary psychological perspectives. He employs interdisciplinary approaches involving economic games and surveys.
