Rationality, logic, and fast and frugal heuristics Academic Article uri icon


  • Gigerenzer and his co-workers make some bold and striking claims about the relation between the fast and frugal heuristics discussed in their book and the traditional norms of rationality provided by deductive logic and probability theory. We are told, for example, that fast and frugal heuristics such as Take the Best replace the multiple coherence criteria stemming from the laws of logic and probability with multiple correspondence criteria relating to real-world decision performance. This commentary explores just how we should interpret this proposed replacement of logic and probability theory by fast and frugal heuristics.
