Components of affective polarization.
(a) Affective component: no relation between disagreement and hostility on the left, strong correlation between disagreement and hostility on the right. (b) Social distance component: individuals are randomly connected in the left graph, whereas there are distinguishable, politically aligned communities in the right graph.

Affective component (hostility distribution).
From top to bottom: network where the node color reflects opinion, from –1 (blue), passing 0 (white), to + 1 (red); scatter plot with disagreement on the x-axis and hostility on the y-axis; values of ,

For each week between February and July 2020, the figure shows: (A) the overall level of affective polarization (), (B) the affective component (
), and (C) the social distance component (
). (B) and (C) provide a decomposition of the overall affective polarization score shown in (A).
