Empirical research on Rational Choice Theory has brought up two focus of the economics laws problem. On one hand, we find the authors who state that the neoclassical economics laws are explanatory and predictive on specific cases: in transparent contexts in which the standard rationality operates successfully. On the other hand, we find the authors who state that the descriptive theories of the rational choice opens up a research path in which fundamental principles of the neoclassical building could be questioned. (...) Both view points have generated an important standard Rational Choice Theory revision what has produced the so called descriptive view point . It implies understanding that most of the choices take place under risky or uncertainty conditions and, that, these choices are far more complex than the normative Rational Choice Theory supposes. This article's main goal is to expand the descriptive point of view in rational choice, theorizing how some factors, coming from the social and cultural environment, operate within the rational choice. Into space of this research essay we find the debatable question of whether these sort of proposals expands the explanation of the deviation of the rational choice normative theory, and that, of the disturbing causes of the microeconomics laws, or they call into question fundamental principles of these laws and therefore they are opening the possibility to focus some economics issues in a new different manner.
