Evolutionary Games without Rationality?

Abstract

It is sometimes claimed that evolutionary game theory provides a basis for doing without rationality. The author defends the thesis that on any plausible construal of the assumptions underlying evolutionary game theory, it cannot provide a plausible basis for deviations from rationality. But on any plausible construal of rationality, evolutionary game theory cannot provide an alternative that coincides with the outcomes dictated by considerations of rationality, either.
