The Bounded Rationality Theory, the Rational Choice Theory or the Methodological Individualism
AbstractThe bounded rationality theory (BRT) has been perceived by social scientists as a more flexible version of the rational choice theory (RCT), also called expected utility theory. The former has the avantage of taking into consideration the fact that information is generally costly. It corrects the RCT on an important point. For the social sciences, the RCT is very useful, but far from representing a general theory which could explain the various kinds of behaviour the social sciences are confronted to, even in its more flexible BRT version. The article makes the postulates underlying the RCT and the BRT explicit and shows that, when some of the postulates are eliminated, a genuinely general model is obtained: the model which is actually used in convincing sociological analyses. La ThÃ©orie de la rationalitÃ© limitÃ©e (TRL) a Ã©tÃ© perÃ§ue par les sciences sociales comme une version assouplie de la thÃ©orie du choix rationnel (TCR), aussi appelÃ©e ModÃ¨le de lâ€™utilitÃ© espÃ©rÃ©e. La TRL a lâ€™avantage de tenir compte notamment du fait que lâ€™information est gÃ©nÃ©ralement coÃ»teuse, corrigeant ainsi lâ€™irrÃ©alisme de la TCR sur un point essentiel. Du point de vue des sciences sociales, la TCR est fort utile, mais elle est loin de proposer une thÃ©orie gÃ©nÃ©rale de la rationalitÃ© permettant de rendre compte des divers types de comportement dont les sciences sociales ont Ã connaÃ®tre, mÃªme dans sa version assouplie de la TRL. On identifie ici les postulats de la TCR et de la TRL et lâ€™on montre quâ€™en abandonnant certains de ces postulats, lâ€™on dÃ©finit un modÃ¨le, le MRG (modÃ¨le rationnel gÃ©nÃ©ral) qui, lui, peut prÃ©tendre Ã la gÃ©nÃ©ralitÃ©. Câ€™est celui qui est utilisÃ© naturellement par les analyses sociologiques qui ses sont imposÃ©es.
