Read moreThe ecological approach to rationality, exemplified in theories such as Gerd Gigerenzer’s Fast and Frugal Heuristics, posits that different decision-making procedures are rational in various decision environments. In this regard, the ecological approach sharply contrasts with standard normative theories like Expected Utility Theory, which is often viewed merely as an analysis of bounded rationality. In this article, I aim to provide philosophical foundations for the ecological approach as a framework for normative rationality. I draw on John Norton’s Material Theory of Induction to argue that the appropriate method for addressing uncertain evidence is domain-dependent and sensitive to the environment, as the ecological approach suggests. Furthermore, I argue that, motivated by insights from material theory, we should re-examine the claim that consistency requirements are universal standards of rationality in three ways: first, the plausibility of consistency axioms depends on the decision environment; second, the application of standard theories is contingent upon the structural conditions of that environment; and third, arguments for axioms, such as money-pump arguments, are plausible only in specific domains. Finally, I argue that the ecological approach can provide a substantive account of rationality norms and that its performance-related criteria for these norms should facilitate the evaluation and modification of agents’ decision-making. These arguments underscore the advantages of the ecological approach over standard theories while situating it within the broader philosophical framework of induction.
