Summary: Punishment and reputation-based mechanisms are crucial in supporting human cooperation and countering offenses. Studies show that decision rules guiding different punishment tactics should consider both the benefits of changing behavior of others and the potential costs of retaliation.

Summary: This study finds that a trust-driven updating rule based on reputation can significantly promote the level of cooperation. Increasing the heterogeneity parameter helps to enhance cooperation. The correlation between node degree and reputation heterogeneity has an impact on cooperation.

Summary: Research shows that gossip is used in daily life to impact and update the reputation of others, enabling partner selection and indirect reciprocity. Gossip senders frequently share information about targets' cooperativeness, and receivers overwhelmingly believe gossip to be true, updating their evaluation of targets based on gossip. These evaluations impact intentions to help or avoid targets in future interactions.

Summary: Indirect reciprocity is an important driver of reputation-based cooperation, but there is mixed evidence on its scope. Some studies suggest that it is bounded by in-group membership, while others suggest it is unbounded. This study proposes a new perspective, the dynamic indirect reciprocity perspective, which integrates these two perspectives. The findings suggest that the cue of reputational consequences determines the perceived realm of indirect reciprocity and influences how individuals condition their cooperation.

Summary: Indirect reciprocity is a driving force behind reputation-based cooperation, but previous studies have conflicting evidence about its scope. Some studies suggest that people only display reputation-based cooperation towards in-group members, while others show that they also cooperate with out-group members, indicating that indirect reciprocity is unbounded. We propose a new perspective, the dynamic indirect reciprocity perspective, which integrates the bounded and unbounded views, and suggest a rigorous preregistered study to test hypotheses derived from this perspective.

Summary: Indirect reciprocity is a key mechanism in understanding cooperation among individuals, where reputations and empathy play important roles. Research suggests that costly reputation spread, interaction observability, and empathy are determinants of cooperation under IR, affecting the level of complexity and information requirements for cooperation.

Summary: Gossip is seen as a way to help with cooperation issues in humans, but ensuring the honesty and credibility of information remains a challenge. This study proposes two mechanisms to support the honesty and credibility of gossip, but experiments show that neither cross-checking nor social bonding were able to maintain cooperation effectively.

Summary: Reputations play a critical role in human social life, allowing people to share and act on information about others. The study combines network approaches with interpersonal perception research to investigate hearsay-based reputations. Results show that hearsay reputations are as positively biased as direct reputations, with strong consensus but modest accuracy, influenced by perceivers' extraversion and affecting perceptions of targets as leaders or friends.

Summary: Avoiding social dilemmas requires partners to sacrifice benefits to help each other in a cooperative system. Super-rational aspiration induced strategy updating in an asymmetric prisoner's dilemma game can effectively promote cooperation among egoistic agents.

Summary: Cooperation problems are common among living organisms and hard to solve. Through third-party communication (gossip), cooperation can be established among individuals. However, to sustain cooperation, gossip should include personal evaluations, perspective taking, and exchange of information about cooperation.

Summary: The study shows that individuals are more willing to cooperate with ingroup members even when they have the same high reputation as outgroup members. However, in the context of low cooperative reputation, the level of cooperation closely mirrors reciprocal expectations. The findings suggest that both reciprocal expectations and social identity contribute to ingroup favoritism, but their relative importance may vary depending on contextual factors. Further experimental research is recommended to explore how reciprocity and social identity interact with other factors, such as partner reputation, in social exchange games.

Summary: Individual reputation evaluation and updating are crucial for game cooperation, and the timescale of reputation updating affects cooperation behavior. A novel adaptive reputation-update rule, incorporating the number of cooperative strategies in historical memory, significantly improves the emergence of cooperation, even surpassing conventional second-order reputation-based PGG. These results contribute to understanding cooperation emergence theoretically and designing a reasonable reputation-updating rule in practice.

Summary: Large-scale non-kin cooperation is a unique element of human success, with reputation and gossip playing a crucial role in promoting cooperation. However, important details of reputation systems are still unclear despite decades of research.
