# Representation facilitates reasoning: what natural frequencies are and what they are not

@article{Hoffrage2002RepresentationFR, title={Representation facilitates reasoning: what natural frequencies are and what they are not}, author={U. Hoffrage and G. Gigerenzer and S. Krauss and L. Martignon}, journal={Cognition}, year={2002}, volume={84}, pages={343-352} }

A good representation can be crucial for finding the solution to a problem. Gigerenzer and Hoffrage (Psychol. Rev. 102 (1995) 684; Psychol. Rev. 106 (1999) 425) have shown that representations in terms of natural frequencies, rather than conditional probabilities, facilitate the computation of a cause's probability (or frequency) given an effect--a problem that is usually referred to as Bayesian reasoning. They also have shown that normalized frequencies--which are not natural frequencies--do… Expand
