Description: This project examined how gossip affects cooperation in situations that vary in strategic motivations (e.g., fear of rejection by one's partner) and its downstream consequences for subsequent cooperation. In a lab experiment involving real-time interactions among 80 triads (N = 240), participants were randomly assigned to act as different roles (i.e., Person A, B, and C) in two games: (1) a dictator game or an ultimatum game involving Person A and Person B; (2) a trust game involving Person C and Person A. We also manipulated whether Person B could gossip about Person A's behavior through sending an evaluation of that behavior to Person C. Overall, we measured Person A's behaviors in the two games, Person B's emotions and evaluations in response to Person A's behavior, and Person C's trust decisions toward Person A in the trust game.
