Fig. 1

Time evolution of a simulation run. We show the outbreak size (a and b) and the fraction of conformists (c and d) for a short \(m=2\) (a and c) and a long \(m=8\) (b and d) memory length. The plots also show two initial fractions of conformists, \(c=0.5\) (blue curves) and \(c=0.9\) (yellow curves). The population seems unable (respectively, able) to eventually reduce the outbreak size irrespective of the memory length when the initial fraction of conformists is high (moderate). Short (long) memory seems insufficient (sufficient) to trigger a substantial interchange of imitation mechanisms among individuals compared to the initial state. Long memory thus helps to eliminate outbreaks when the initial fraction of conformists is moderate (blue curve in panel b). Here, the infection rate is relatively large, \(\beta =2\). The networks are constructed by the Erdős–Rényi model with \(N=64\) nodes and the average degree \(k=2\), which ensures the existence of a giant component (that essentially all nodes belong to). Time is measured in the number of vaccination cycles
