This is a contribution to the growing experimental literature on how trial-and-error adjustment processes can establish a convention for coordination on an equilibrium in a game. A simple bargaining game introduced by Nash is used for this purpose. Subjects are conditioned in different treatments to use four different bargaining solutions. The stability of the conditioning is then studied as the bargaining game is played over an extended period. The data obtained is unusually sharp. In the long

The results are therefore not supportive of the view that strategic considerations in such situations can be neglected in favor of a study of fairness norms. Indeed, the equilibrium actually achieved in a session turns out to be a very good predictor of what the median subject says is "fair" in the game after play is over. Early mankind soon reached the grand generalization that everything has its price, everything can be paid for. Here we have the oldest and most naive moral canon of justice, of all "fair play", "good will", and "objectivity". Justice at this level is good will operating among men of roughly equal power, their readiness to come to terms with one another, to strike a compromise o., Friedrich Nietzsche, The Generalogy of Morals
