The effects of exposure (E) as a function of tolerance (T). Average polarization of the population’s ideological positions after 2,000,000 steps, averaged over 20 iterations for each $\left(T,E\right)$ pair. Tolerance is varied over $T=0.05,0.1,\dots ,1.0$, and exposure is varied over $E=0.05,0.1,\dots ,0.5$.
