Toward an Evolutionary Theory of Rationality

Abstract

Since the dawn of time, humankind's singular ability to make decisions has allowed human beings to face innumerable environmental challenges and complex evolutionary dynamics. Environmental pressures are not so urgent anymore, comparing to our ancestors. Nonetheless, the number of decisions that contemporary humans are called to make is very high. During the last three centuries, the change from normative to descriptive theories, from formal to natural logic, from substantive to limited rationality has allowed us to explain how many of the decisional strategies are coherent with the functioning of the cognitive economy of our species, even if they are limited and fallible.
