Abstrakt: The article discusses the concept of indirect reciprocity and its potential to foster large-scale cooperation. The authors present a theoretical model in which agents interact across two stages, choosing actions based on cooperation with their own group or with other groups. The authors conclude that indirect reciprocity alone is insufficient for stabilizing large-scale human cooperation. However, new research suggests that when interactions across group boundaries become possible, indirect reciprocity can promote large-scale cooperation. The article also addresses the questions of whether people actually implement conditional reputation strategies when interacting with out-group members and to what degree belonging to a group restricts interaction frequency with out-group members. The research shows that people do provide aid to both in-group and out-group members and that intergroup cooperation can be mutually reinforced. The article emphasizes that belonging to a group does not prevent interactions with out-group members and that the likelihood of such interactions increases with larger group sizes and growing social mobility. Overall, the findings suggest that indirect reciprocity can foster large-scale cooperation and individuals use it to shift others' behavior from in-group to intergroup cooperation.
