Answer: c. Moved away from a strictly rational reasoning model for rational thought.
Recently, the rational choice theory has been criticized for leaving out some important factors that might influence the choices people make. Institutions and uncertainty can lead people to make a choice they would not have made under unconstrained circumstances solely dependent on reason. Therefore, new concepts have arisen, such as the "bounded rationality" idea. This is an attempt to recognize the limits that rationality has in real life.
Some works that have dealt with this problematic are: Pathologies of Rational Choice Theory (Green and Shapiro, 1994) and Neuropolitics (William E. Connolly, 2002).
