In the nonconventional economic literature decision processes are mainly analyzed on the basis of cognitive aspects (such as the existence of limited rationality) and institutional aspects (such as rules of thumb, institutions and conventions). The fuzzy logic, in turn, offers a form of treating the decision process when agents only have imprecise and subjective information in a context of complexity and uncertainty. This paper discusses the points of convergence and complementarities between the fuzzy logic and the theory of behavior based on limited rationality and rule-guided economic behavior.
