“…Previous studies have confirmed that reciprocity is required for sustained cooperative behavior among both humans and animals [43][44][45][46] . The results of our study are consistent with these findings as we demonstrated that first, experiencing non-reciprocity to cooperative behavior (viz., having a sucker experience in the PDG) strongly decreased the likelihood of repeated cooperation; and second, reciprocity to cooperation (i.e., a reward outcome) enhanced the probability in the subsequent rounds.…”

“…In this respect, it is important to stress that we used an iterated stranger design, which implies that each player only interacts once with each other player in the group without knowing whether they cooperated in the previous rounds playing with others. Contrary to the case of repeatedly interacting with the same player, no strategy based on direct reciprocity (e.g., tit-fortat strategy) 44 can be reasonably applied. Also indirect-reciprocity strategies, where information about previous interactions with other persons can be taken into account during the current interaction, or the behavior in the current interaction may be considered in future interactions (e.g., based on reputation) 47 , are ruled out.…”

The level of moral development may be crucial to understand behavior when people have to choose between prioritizing individual gains or pursuing general social benefits. This study evaluated whether two different psychological constructs, moral reasoning and moral competence, are associated with cooperative behavior in the context of the prisoner's dilemma game, a two-person social dilemma where individuals choose between cooperation or defection. One hundred and eighty-nine Mexican university students completed the Defining Issues Test (DIT-2; measuring moral reasoning) and the Moral Competence Test (MCT) and played an online version of the prisoner’s dilemma game, once against each participant in a group of 6 to 10 players. Our results indicate that cooperative behavior is strongly affected by the outcomes in previous rounds: Except when both participants cooperated, the probability of cooperation with other participants in subsequent rounds decreased. Both the DIT-2 and MCT independently moderated this effect of previous experiences, particularly in the case of sucker-outcomes. Individuals with high scores on both tests were not affected when in previous rounds the other player defected while they cooperated. Our findings suggest that more sophisticated moral reasoning and moral competence promote the maintenance of cooperative behaviors despite facing adverse situations.

“…Without exaggeration, hundreds of research papers were published by scientists with biology, economics, applied mathematics, or statistical physics background, in which they proposed different microscopic models to increase the general willingness of actors to cooperate with their partners [8,9,10,11,12]. In some cases the desired evolutionary outcome is expected, for example when defection is punished or cooperation is awarded by individuals or by a governing institution [13,14,15,16,17,18,19].…”

The self-organizing impact of averaged payoffs on the evolution of cooperation

According to the fundamental principle of evolutionary game theory, the more successful strategy in a population should spread. Hence, during a strategy imitation process a player compares its payoff value to the payoff value held by a competing strategy. But this information is not always accurate. To avoid ambiguity a learner may therefore decide to collect a more reliable statistics by averaging the payoff values of its opponents in the neighborhood, and makes a decision afterwards. This simple alteration of the standard microscopic protocol significantly improves the cooperation level in a population. Furthermore, the positive impact can be strengthened by increasing the role of the environment and the size of the evaluation circle. The mechanism that explains this improvement is based on a self-organizing process which reveals the detrimental consequence of defector aggregation that remains partly hidden during face-to-face comparisons. Notably, the reported phenomenon is not limited to lattice populations but remains valid also for systems described by irregular interaction networks.
