Figure 2. The “wisdom of groups” promotes the evolution of cooperation irrespective of the properties of the interaction network.

In this figure the prisoner's dilemma game was staged on the honeycomb lattice. Depicted is the fraction of cooperators ρ_C in dependence on the temptation to defect b, as obtained for different values of α (see figure legend). As by the results obtained on the square lattice depicted in Fig. 1, it can be observed that the larger the value of α the higher the value of b where cooperators outperform defectors.
