Impact of the initiator’s initial performance. (A) The initiator’s cumulated social influence $S$ decreases with increasing error of the initiator during the training phase. (B) Increasing the connectivity of the initiator enhances the reach of judgment propagation, but this effect is compensated by increasing error of the initiator during the training phase. Both high connectivity and good performances of the initiator are necessary ingredients for creating strong judgment propagation (i.e., high cumulated social influence). Simulation results are computed after a training phase of 50 rounds of interactions and averaged over 1,000 simulations. The model parameters are identical to those used in the main text, namely, ${\tau }_1=15°$, ${\tau }_2=55°$, $\omega =2$, and $d_a=20°$.
