Rational Choice Theory or Pretense? The Claims, Equivalences, and Analogies of the “Economic Approach to Human Behavior”

The article argues and demonstrates that classical–neoclassical economics generally does not pretend or claim that its principles apply to domains beyond the economy, specifically wealth, and does not equate the economic and the noneconomic, and the rational and the nonrational. By contrast, the “economic approach to human behavior” or “rational choice theory” precisely does this to legitimize itself by invoking classical–neoclassical economics as supreme authority and its representatives as venerable precursors. The article reveals the economic approach to human behavior as a set of grand theoretical and methodological claims, equivalences, and analogies from the standpoint of conventional economics itself, as well as sociology and other social sciences. It identifies and examines certain indicative instances of such tendencies. The article aims to contribute to understanding better the relations—or rather lack thereof—between conventional economics and contemporary economic and sociological rational choice theory. The economic approach to human behavior is not new, even outside the market sector. The rational choice model provides the most promising basis presently available for a unified approach to the analysis of the social world by scholars from different social sciences. — Gary Becker With respect to those parts of human conduct of which wealth is not even the principal object, to these political economy does not pretend that its conclusions are applicable. — John S. Mill But economy does not treat of all human motives. There are motives nearly always present with us, arising from conscience, compassion, or from some moral or religious source, which economy cannot and does not pretend to treat. These will remain to us as outstanding and disturbing forces; they must be treated, if at all, by other appropriate branches of knowledge. — William Jevons A science, therefore, based on the hypothesis (of universal rationality) would yield a general form of the social phenomenon having little or no contact with reality … — Vilfredo Pareto
