Query: 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.
