ABSTRACTChristopher Achen and Larry Bartels argue, in Democracy for Realists, that voters tend to be not only politically ignorant but irrationally attached to group identities. That they use group identities is not in dispute, but the irrationality of doing so is questionable. The instability and malleability of group identities suggests that they are more than primal, illogical attachments. While Achen and Bartels assume that they must be affective, they may in fact be rational. They may, for example, serve as heuristics (...) for individual interests. (shrink)

Don Green and Ian Shapiro's Pathologies of Rational Choice Theory, despite the impressive amount of work that has gone into it, is undercut by a number of serious misunderstandings of the use of the rational choice approach by students of American politics. Furthermore, Green and Shapiro adopt an extremely pinched notion of an empirical contribution and an outmoded and idealized view of the scientific method. If their standards were adopted, it would be difficult to allow that anyone in political science (...) has made an empirical contribution, or that political science is a scientific enterprise.
