Percentages of farms changing disease and action state over the length of the simulation at differing probabilities of bringing-in the disease with the riskier action, and two distributions of payoffs.

In the left column we show results from simulations of idealist farms which compare their payoffs to a set general payoff estimate, and on the right results from simulations of realist farms that compare only to payoffs they have experienced. 95% confidence envelopes are plotted in pale shading around each line.
