Computer simulation of the Seceder mechanism of Dittrich et al. and Halpin-Healy et al.48,49,50. Though a similar finding of emergent branches appears for more general dimension choices, for illustrative purposes we generated this output by splitting the simple one-dimensional output into values from 0 to 0.5 to provide one axis (branches and clustering shown in orange) and 0.5 to 1 to provide another (branches and clustering shown in blue) hence the triangular shape for the x axis. The green branch mimics the Boogaloo movement and classifies as ‘elsewhere’ since it is neither on the left or right of the one-dimensional axis. Each colored dot represents the position of an agent in the system at a particular time and with a particular value along the one-dimensional line. The branches emerge as a result of the model’s competition between the pressure to conform and the desire to dissent. The plot shows the aggregation of agents around specific values, so the wider the line, the more agents with similar values in that branch. Since the vertical axis is time in the computer simulation, each branch generates a tall structure with height equal to the time. Since the sizes of these branches of individuals fluctuate as time progresses, these tall structures have non-constant width.
