Updating of imitation mechanisms often leads to disease-curbing, moderate levels of conformism, but only if memory is long enough. We show heatmaps of the outbreak size (a and b) and the fraction of conformists (c and d) as a function of the infection rate and initial conformism. When the infection rate is low, the outbreak size is independent of the initial conformism, which is evident from the horizontal contour curves for \(\beta \lessapprox 0.5\) in a and b. As the infection rate increases, however, high initial conformism causes severe outbreaks. Short memory fails to improve the situation because the level of conformism changes little compared to initial conformism, which is seen in the almost vertical contour curves in c. Long memory, by contrast, often improves the situation by adjusting initial conformism to disease-curbing, moderate levels between 40 and 60 %, as seen in d. Every point is averaged over the last 50 vaccination cycles
