There are two related dimensions to the evolution–rationality connection. The first is the evolution of rationality itself, thought of as an actual phenotypic attribute of some organisms; the second is the use of rationality-inspired concepts to describe evolved organisms, as in agential thinking. Rationality may be understood either as consistency of choice or as having good reasons for beliefs/actions; these notions have distinct domains of application. The adaptive significance of rationality over arationality is clear; what is less clear is whether evolution would always favour rationality over irrationality. In a simple model, an evolutionary basis for the norms of Bayesian rationality emerges; however, the model relies on restrictive assumptions. The possibility of an evolutionary naturalization of traditional rationality norms, though philosophically coherent, appears empirically unlikely.

Cette note examine la partie conceptuelle d’un article de Sen, «Internal Consistency of Choice». Elle isole deux thèses parmi celles que Sen défend. Une première, négative, est qu’aucune condition formelle de cohérence du choix n’est normativement valable sans exception. Une seconde, positive, est qu’une condition formelle de cohérence du choix n’est normativement valable que sous des suppositions faisant intervenir la préférence. Nous procédons à une analyse détaillée des choix énigmatiques dont Sen prend argument et affirmons que cet examen mène à remettre en cause la thèse négative, mais d’une manière subtile qui confirme — même renforce — la thèse positive.
