Game of Chicken

The Game of Chicken (known in evolutionary biology as the Hawk-Dove game) models an escalation conflict in which yielding signals weakness but mutual stubbornness leads to disaster. Two drivers race head-on: swerving (Dove) means losing face; driving straight (Hawk) means holding firm. The worst outcome is mutual Hawk.

Unlike the Prisoner’s Dilemma, here mutual defection (both drive straight) is the catastrophic outcome, not merely a poor one. There are two asymmetric pure Nash equilibria: one swerves, the other drives straight — whoever swerves loses, whoever holds wins. Neither player wants to be the one who swerves, yet both want to avoid catastrophe. Victory therefore hinges on commitment: making it credible that you can no longer swerve — for instance by visibly throwing the steering wheel out of the window — forces the other into the Dove role.

For escalation conflicts with a catastrophic worst case: geopolitical crises (the Cuban Missile Crisis), labor disputes and strikes, market-entry deterrence, hostile acquisitions, brinkmanship in negotiations. Whenever both sides apply pressure, neither wants to yield first, and a collision ruins everyone.

The central lever is credible commitment: a commitment device that visibly destroys your own option to retreat and thereby forces the other to swerve — paradoxically, you win by removing your own choice. Defensively the opposite helps: hand the decision to a neutral third party / arbitrator to avoid an accidental catastrophe, or keep communication channels open so escalation can be deliberately de-escalated.

The Cuban Missile Crisis, where the US and USSR went to the brink of nuclear war. Two corporations in a price war that ruins both if neither yields. A union and an employer pushing a strike to mutual harm. A startup signaling to an incumbent that it will enter the market whatever the cost.
