Abstract: How cooperation persists and evolves remains an open question. Here, we incorporate neighbors’ wisdom to the calculation of players’ replicate ability via a single parameter α. Through extensive numerical simulations, we find that positive α modifies players’ reproductive ability, where cooperative clusters become more compact and can attract more defectors to follow them. Finally, cooperation evolves with the support of this enhanced network reciprocity. For example, we can still observe full cooperation state even at the extremely bad condition that natural selection strongly favors defection. Our work may provide another insight into the understanding of this open question.
