The game of chicken

The game of chicken, also known as the hawk-dove game or snowdrift[1] game, is an influential model of conflict for two players in game theory. The principle of the game is that while each player prefers not to yield to the other, the worst possible outcome occurs when both players do not yield.

The name “chicken” has its origins in a game in which two drivers drive towards each other on a collision course: one must swerve, or both may die in the crash, but if one driver swerves and the other does not, the one who swerved will be called a “chicken,” meaning a coward; this terminology is most prevalent in political science and economics. The name “Hawk-Dove” refers to a situation in which there is a competition for a shared resource and the contestants can choose either conciliation or conflict; this terminology is most commonly used in biology and evolutionary game theory. From a game-theoretic point of view, “chicken” and “hawk-dove” are identical; the different names stem from parallel development of the basic principles in different research areas.[2] The game has also been used to describe the mutual assured destruction of nuclear warfare, especially the sort of brinkmanship involved in the Cuban Missile Crisis.[3]
