Onymity promotes cooperation in social dilemma experiments
It is proved that reducing anonymity is a valid promoter of cooperation, leading to higher payoffs for cooperators and thus suppressing an incentive—anonymity—that would ultimately favor defection.

While network reciprocity fulfilled its expected role, costly punishment proved to be surprisingly ineffective in promoting cooperation, suggesting that the rational response to punishment assumed in theoretical studies is overly stylized and needs reexamining.

It is shown how the decoy effect can enhance cooperation in a social dilemma, the repeated prisoner’s dilemma, and is pointed to as a means to elicit voluntary prosocial action across a spectrum of collective endeavours.
