When political polarization is modeled as a game the result is Chicken. The technical basics are not very complicated.

Reiterated Prisoner’s Dilemma (RPD) is socially integrative.

Any society adopting these rule-of-thumb principles consolidates. When everyone norms on this strategy, individual and collective interests are harmonized. Things work.

Chicken is very different. Someone blinks first, so the trust-trust mutual optimum of RPD is subtracted in advance. Rather than the four possible outcomes of a single PD round (A and B do OK, A wins B loses, B wins A loses, A and B both lose) there are just three possible outcomes (A wins B loses, B wins A loses, A and B both lose extremely). In Chicken, it is the avoidance of outcome three, rather than the non-existent chance of PD outcome one, that moderates behavior, and then asymmetrically (someone always blinks first).
