In economics and game theory, a participant is considered to have superrationality (or renormalized rationality) if they have perfect rationality (and thus maximize their utility) but assume that all other players are superrational too and that a superrational individual will always come up with the same strategy as any other superrational thinker when facing the same problem. Applying this definition, a superrational player playing against a superrational opponent in a prisoner's dilemma will cooperate while a rationally self-interested player would defect.

  • La superrationalité est un type alternatif de prise de décision autre que la solution la plus connue en théorie des jeux. Un joueur superrationnel jouant le dilemme du prisonnier contre un autre joueur superrationnel va coopérer, alors que traditionnellement, un joueur rationnel ne coopère pas. Cette règle de décision n'est pas très répandue dans la communauté de la théorie des jeux. Le concept de la superrationalité a été créé par Douglas Hofstadter dans un article publié dans son livre (en). Il le définit de manière récursive ainsi : « La pensée superrationnelle est par définition récursive ; les joueurs incluent dans leurs calculs le fait qu'ils sont en train de jouer dans un groupe de penseurs superrationnels. » La superrationalité est proche de la notion, due à Emmanuel Kant, d'impératif catégorique (« Agis de telle sorte que le principe de ton action puisse être érigée en loi universelle »).

  • In economics and game theory, a participant is considered to have superrationality (or renormalized rationality) if they have perfect rationality (and thus maximize their utility) but assume that all other players are superrational too and that a superrational individual will always come up with the same strategy as any other superrational thinker when facing the same problem. Applying this definition, a superrational player playing against a superrational opponent in a prisoner's dilemma will cooperate while a rationally self-interested player would defect. This decision rule is not a mainstream model within the game theory and was suggested by Douglas Hofstadter in his article, series, and book Metamagical Themas as an alternative type of rational decision making different from the widely accepted game-theoretic one. Superrationality is a form of Immanuel Kant's categorical imperative, and is closely related to the concept of Kantian equilibrium proposed by the economist and analytic Marxist John Roemer. Hofstadter provided this definition: "Superrational thinkers, by recursive definition, include in their calculations the fact that they are in a group of superrational thinkers." This is equivalent to reasoning as if everyone in the group obeys Kant's categorical imperative: "one should take those actions and only those actions that one would advocate all others take as well." Unlike the supposed "reciprocating human", the superrational thinker will not always play the equilibrium that maximizes the total social utility and is thus not a philanthropist. (en)
