The Game of Chicken and Brinkmanship

A game with two dangerous equilibria explains why parties sometimes deliberately limit their own options to win a standoff.

Some of the highest-stakes confrontations in business, politics, and international relations resemble a peculiar kind of standoff where backing down is embarrassing but refusing to back down could be disastrous for everyone. Game theorists model this with the game of chicken, and the strategies that emerge from it - sometimes deliberately dangerous ones - are known as brinkmanship.

The setup

The game takes its name from a reckless teenage dare: two drivers speed toward each other, and whoever swerves first “loses,” while whoever doesn’t swerve “wins” - unless neither swerves, in which case both crash. Formally, each player chooses between “swerve” (yield) and “stay the course” (don’t yield). The best outcome for you is that you stay the course and the other player swerves; the worst outcome for both of you is that neither swerves. Unlike the prisoner’s dilemma covered earlier in this module, where mutual defection is merely bad, in chicken mutual defection is catastrophic for both sides.

Two equilibria, and neither is obviously “the answer”

The game of chicken has two Nash equilibria, in the sense covered in the earlier Nash equilibrium lesson: one where you stay the course and the other player swerves, and one where the reverse happens. Neither player wants to be the one who swerves, but somebody generally needs to, or both end up worse off than either equilibrium. This creates real uncertainty about which equilibrium the game actually lands on, and that uncertainty is exactly what makes the game tense and, in real situations, dangerous.

A labor strike standoff

Picture a company and a labor union locked in a standoff over a new contract, each threatening to hold firm right up to a costly strike deadline. If either side backs down and makes concessions first, they get a worse deal than they wanted, but at least a deal happens. If neither side backs down, the strike proceeds and both sides lose money they didn't need to lose. Each side is betting the other will blink first - which is precisely the logic of the game of chicken.

Brinkmanship: winning by removing your own options

Brinkmanship is the strategy of deliberately pushing a confrontation toward the edge of disaster in order to convince the other side that you won’t be the one to back down. Counterintuitively, one of the most effective brinkmanship tactics is to visibly remove your own ability to swerve - for instance, publicly committing to a position in a way that would be humiliating or costly to reverse. If the other player believes you genuinely cannot back down, their only remaining rational move is to swerve themselves, which is exactly the outcome the first player wants.

Assuming removing your options is always a weakness

It seems backwards that limiting your own choices could be an advantage - shouldn't having more options always be better? In a standoff like chicken, though, having the option to back down is precisely what makes it rational for the other side to expect you eventually will. A **credible commitment** that genuinely removes that option can shift the other player's expectations and their behavior, even though it looks, on the surface, like you've made yourself weaker.

Why this shows up in real crises

Brinkmanship-style reasoning appears in labor negotiations, corporate takeover battles, and international standoffs, including nuclear deterrence during the Cold War, where the term “brinkmanship” originated. The strategy carries real risk: if both sides believe they’ve successfully committed and neither can back down, the mutual-disaster outcome becomes far more likely, which is exactly why real-world standoffs modeled this way are worth taking seriously rather than treating as clever tactical games.

Key takeaways

The game of chicken models standoffs where mutual refusal to yield produces the worst outcome for both sides.
It has two Nash equilibria, one where each player yields, and no clear way to know which one applies.
Brinkmanship means pushing a confrontation toward disaster to convince the other side to yield first.
Visibly removing your own ability to back down can be a rational, credible-commitment strategy.
This reasoning appears in labor disputes, corporate battles, and international standoffs like nuclear deterrence.
Brinkmanship carries genuine risk: if both sides successfully commit, the disaster outcome becomes more likely.
