From: Uncertainty about social interactions leads to the evolution of social heuristics

Fig. 2

Uncertainty about the nature of social interactions leads to the evolution of cooperative heuristics. a The fraction of individuals using heuristic strategies and b the average cooperation rate at the end of evolutionary simulations that impose varying levels of uncertainty about social interactions. Grey lines show separate results for 100 different random mutation matrices that determine the probability with which a mutation of each strategy gives rise to each other strategy (every point shows an average over 50 replicate simulations per mutation matrix). The red line and shading provide the estimate of the mean and 95% confidence interval of (a) heuristic decision making and (b) cooperation for the average mutation matrix (modelled as a four-parameter logistic function, see Methods for details)
