Original Position

The original position is the hypothetical situation of choice that John Rawls constructs behind the veil of ignorance: a point of deliberation in which rational agents are deprived of knowledge about their own social position, natural abilities, and conception of the good, yet retain their capacity for rational choice and a thin theory of the good. Rawls argues that the principles of justice chosen from this position possess a special legitimacy because they are not biased by contingent advantage — the chooser cannot rig the game in their own favor because they do not know which player they are. The original position is not a historical event or a prediction about what people would actually choose; it is a device of representation that tests whether proposed principles are robust against a specified class of positional uncertainty. It has structural analogues in mechanism design (strategyproofness under private types) and in robust optimization (performance across distributional uncertainty), suggesting that the original position is one instance of a broader pattern: the use of information constraints to enforce fairness in system design.
