When those who know do share: Group goals facilitate information sharing, but social power does not undermine it

Good team decisions require that team members share information with each other. Yet, members often tend to selfishly withhold important information. Does this tendency depend on their power within the team? Power-holders frequently act more selfishly (than the powerless)—accordingly, they might be tempted to withhold information. We predicted that given a task goal to ‘solve a task’, power-holders would selfishly share less information than the powerless. However, a group goal to ‘solve the task together’ would compensate for this selfishness, heightening particularly power-holders’ information sharing. In parallel, an individual goal to ‘solve the task alone’ may heighten selfishness and lower information sharing (even) among the powerless. We report five experiments (N = 1305), comprising all studies conducted in their original order. Analyses yielded weak to no evidence for these predictions; the findings rather supported the beneficial role of a group goal to ensure information sharing for both the powerful and the powerless.
