Raţionalitatea în economie: de la homo oeconomicus la homo irationalis

The aim of the present paper is an attempt to build a scaffolding with the help of which, the concept of “rationality” will be explored from the philosophic and also economic point of view, with the purpose of highlighting that Econometrics and other purely quantitative scientific demonstrations are subject to serious errors. The starting issue is given by the usage of the "rationality" concept in the economic science, the way that it can change the result of the human action and also the risk of treating the rational as being irrational by only taking into account the results of a sole action.
