Simulations for unconstrained scores, small groups (\(n=8\)). Top left: histograms of scores aggregated over all groups. Blue indicates free riders (that do not follow the norm of cooperating), red indicates norm followers (cooperators). Top right: payoff as a function of the score. Line is the result of a linear regression. Bottom left: average fraction of cooperators as a function of time. Bottom right: average value of the norm internalization attribute as a function of time.
