Rational choice explanations in political science

In this chapter, it is described and assessed how political scientists use rational choice theories to offer causal explanations. We observe that the ways in which rational choice theories are considered to be successful in political science differs, depending on the explanandum in question. Political scientists use empirical variants of rational choice theories to explain the political behavior of individual agents and analytical variants to explain the behavior of collective actors. Both variants are used for distinct explananda, which ask for different modes of explanation that raise in turn different explanatory demands toward rational choice theories. We argue that when political scientists discuss the explanatory usefulness of rational choice theories, they should assess them in light of the demands they are supposed to meet. This would enable a more nuanced and problem-oriented appraisal of rational choice theories in political science.
