Figure 2. — The effect of varying how difficult the political game is, as determined by the threshold variance in individual opinions necessary to reach consensus, x_thr on (a) hierarchy, (b) institutional rules and individual preferences, (c) group size and (d) frequency of each strategy in the population. Lower x_thr represents a more difficult political game, in which individuals have a higher stake and so find it more difficult to reach consensus. The boxplots represent measures across 50 000 generations and 10 replicates, and are over patches. Error bars in plot (d) represent the standard deviation.
