Fig. 8. Evolution of individual positions in two groups across polarization scenarios with a 10% mutation rate: (a) no polarization, (b) intragroup polarization, and (c) intergroup polarization. Purple circles show examples of mutation. Yellow arrows indicate intergroup interactions and purple arrows indicate intragroup interactions. Solid arrows show formal interactions and dashed arrows show informal interactions. (Note: only some meetings are indicated.)
