Naturalistic Decision Making and Intelligence of unconscious

During the last three centuries, the change from formal to natural logic 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. The dif culty in deciding and facing up to uncer- tainty is not only linked to the inadequacy of the architecture of our minds but also to an ‘external’ model of uncertainty which does not correspond to the way in which our mind naturally functions. New conceptual paradigms and new programmes for experimental research are called for in order to rede ne the role of internal and external restrictions on human action (re- sources and available information, limitations on calculation ability, on the capacity of memory, cognitive styles, representations and perceptions of risk, unconscious inferences and so on).
