I critically discuss a recent innovation in the debate surrounding the plausibility of rational choice theory (RCT): the appeal to evolutionary theory. Specifically, I assess Gigerenzer and colleagues’ claim that considerations based on natural selection show that, instead of making decisions in a RCT-like way, we rely on ‘simple heuristics’. As I try to make clearer here, though, Gigerenzer and colleagues’ arguments are unconvincing: we lack the needed information about our past to determine whether the premises on which they are built are true—and, hence, we cannot tell whether they, in fact, speak against RCT.
I would like to thank Elliott Sober, Dan Hausman, Larry Shapiro, Katie Steele, and Gerd Gigerenzer for helpful comments on previous versions of this article.
