Abstract

It is sometimes claimed that evolutionary game theory provides a basis fordoing without rationality. The author defends the thesis that on any plausibleconstrual of the assumptions underlying evolutionary game theory, it cannotprovide a plausible basis for deviations from rationality. But on any plausibleconstrual of rationality, evolutionary game theory cannot provide an alternativethat coincides with the outcomes dictated by considerations of rationality,either. Key Words: evolutionary game theory • game theory • rationality • Skyrms.
