Unification, universalism, and rational choice theory

Green and Shapiro's critique of rational choice theory underestimates the value of unification and the necessity of universalism in science. The central place of intentionality in social life makes both unification and universalism feasible norms in social science. However, “universalism” in social science may be partial, in that the independence hypothesis—that the causal mechanism governing action is context independent—may hold only locally in certain classes of choice domains.
