      Does Observability Amplify Sensitivity to Moral Frames? Evaluating a Reputation-Based Account of Moral Preferences

      By: Valerio Capraro, Jillian J. Jordan and Ben Tappin
      A growing body of work suggests that people are sensitive to moral framing in economic games involving prosociality, suggesting that people hold moral preferences for doing the “right thing”. What gives rise to these preferences? Here, we evaluate the explanatory power... View Details

      False Signaling and Personal Moral Failings: Two Distinct Pathways to Hypocrisy with Unequal Moral Weight

      By: Jillian J. Jordan and Roseanna Sommers
      Moral engagement is a key feature of human nature: we hold moral values, condemn those who violate those values, and attempt to adhere to them ourselves. Yet moral engagement can make us appear hypocritical if we fail to behave morally. When does moral engagement risk... View Details

      Signaling When Nobody Is Watching: A Reputation Heuristics Account of Outrage and Punishment in One-shot Anonymous Interactions

      By: Jillian J. Jordan and David G. Rand
      Moralistic punishment can confer reputation benefits by signaling trustworthiness to observers. However, why do people punish even when nobody is watching? We argue that people often rely on the heuristic that reputation is typically at stake, such that reputation... View Details

      When Do We Punish People Who Don't?

      By: Justin W. Martin, Jillian J. Jordan, David G. Rand and Fiery Cushman
      People often punish norm violations. In what cases is such punishment viewed as normative—a behavior that we “should”or even“must”engage in? We approach this question by asking when people who fail to punish a norm violator are, themselves, punished. (For instance, a... View Details

      Which Accusations Stick?

      By: Jillian J. Jordan
      The social function of witchcraft accusations remains opaque. An empirical study of Chinese villagers shows that the label ‘z hu’ influences who interacts across a social network, but appears not to tag defectors in service of promoting cooperation. An open question... View Details

      Third-Party Punishment as a Costly Signal of High Continuation Probabilities in Repeated Games

      By: Jillian J. Jordan and David G. Rand
      Why do individuals pay costs to punish selfish behavior, even as third-party observers? A large body of research suggests that reputation plays an important role in motivating such third-party punishment (TPP). Here we focus on a recently proposed reputation-based... View Details

      Why Do We Hate Hypocrites? Evidence for a Theory of False Signaling

      By: Jillian J. Jordan, Roseanna Sommers, Paul Bloom and David G. Rand
      Why do people judge hypocrites, who condemn immoral behaviors that they in fact engage in, so negatively? We propose that hypocrites are disliked because their condemnation sends a false signal about their personal conduct, deceptively suggesting that they behave... View Details

      No Unique Effect of Intergroup Competition on Cooperation: Non-competitive Thresholds Are as Effective as Competitions between Groups for Increasing Human Cooperative Behavior

      Explaining cooperation remains a central topic for evolutionary theorists. Many have argued that group selection provides such an explanation: theoretical models show that intergroup competition could have given rise to cooperation that is costly for the individual.... View Details

      The Effects of Endowment Size and Strategy Method on Third Party Punishment

      Numerous experiments have shown that people often engage in third-party punishment (3PP) of selfish behavior. This evidence has been used to argue that people respond to selfishness with anger, and get utility from punishing those who mistreat others. Elements of the... View Details

      Uncalculating Cooperation Is Used to Signal Trustworthiness

      Development of In-Group Favoritism in Children's Third-Party Punishment of Selfishness
