Computer simulations of the relation between individual heuristics and global cooperation in prisont in highly competitive PDG settings, using a competitive type of social comparison for performance evalution, cooperative behavior is maintained in large groups. There remain however several findings which need further study before we better understand the relation between individual heuristics and their global consequences.
