We are concerned about analyzing in this process, the qualification of rational or irrational according to different currents of thought, within the framework of the Decision Theory. We will tackle a bit of history and characterization of the problematic of rationality that has been in force throughout the history of mankind. Beginning with the strong rationality: Mario Bunge (Argentine philosopher, analyzing the contributions of Herbert Simon and Daniel Kahneman Nobel Prizes), until reaching the Minimum Instrumental Rationality Theory (Elster, Pavesi.)We will also distinguish moral and ethical concepts, badly linked to rationality.We will present as final reflections the precepts of the Decision Theory and some criticisms of the Minimum Instrumental Rationality Theory, based on what has been researched and with the varied contribution of the selected authors, giving special importance to the weak aspects observed in said theory. Classification-JEL: M16. Keywords: Rationality, Subjectivity, Decision.
