This paper returns to a perennial controversy I examined in a previous paper in the Journal of Business Ethics (Vol. 2, 1983). Is economic theory an ethically neutral discipline or do its statements presuppose a commitment to moral values? Once again this issue is addressed via a case study of the neo-classical theory of rational choice. In the present paper I focus on behaviourist forms of operationalist attempts to short-circuit any argument that would seek to infer moral presuppositions from the (...) use of evaluative discourse. In particular, I examine strategies that have sought to excise from economic theory the mentalistic vocabulary required to describe valuations per se. And I argue that such tactics are deficient since they i) impoverish the explanatory power of economic theory, (ii) fail to recover the normative usefulness of the theory of choice, and (iii) camouflage the continued presupposition of moral commitments within neo-classical theory.

The question of reductionism is an obstacle to unification. Many behavioral scientists who study the more complex or higher mental functions avoid regarding them as selected by motivation. Game-theoretic models in which complex processes grow from the strategic interaction of elementary reward-seeking processes can overcome the mechanical feel of earlier reward-based models. Three examples are briefly described. (Published Online April 27 2007).

The various behavioral disciplines model human behavior in distinct and incompatible ways. Yet, recent theoretical and empirical developments have created the conditions for rendering coherent the areas of overlap of the various behavioral disciplines. The analytical tools deployed in this task incorporate core principles from several behavioral disciplines. The proposed framework recognizes evolutionary theory, covering both genetic and cultural evolution, as the integrating principle of behavioral science. Moreover, if decision theory and game theory are broadened to encompass other-regarding preferences, they (...) become capable of modeling all aspects of decision making, including those normally considered “psychological,” “sociological,” or “anthropological.” The mind as a decision-making organ then becomes the organizing principle of psychology.
