This article argues that the problems identified in the literature on public choice should critically affect our research on public opinion and our understanding of the impact of public opinion on foreign policy. While a robust literature has emerged around social choice issues in political science, there has been remarkably little appreciation for these problems in the literature on public opinion in general and on public opinion and foreign policy in particular. The potential importance of social choice problems for understanding the nature and role of public opinion in foreign policy making is demonstrated through an examination of American public attitudes about military intervention abroad. In particular, drawing on several common descriptions of the underlying dimensionality of public attitudes on major foreign policy issues, it is shown that there may be important intransitivities in the ordering of public preferences at the aggregate level on policy choices such as those considered by American decision makers in the period leading up to the Gulf War. Without new approaches to public-opinion polling that take these problems into consideration, it will be difficult to make credible claims about the role of public opinion in theforeignpolicy process.
