Public Opinion and Policy Representation: On Conceptualization, Measurement, and Interpretation

The congruence between public preferences and public policy is of special importance in representative democracies. We want to know whether the public is getting the policies it wants and, if not, whose preferences are being represented. To directly evaluate congruence, scholars need to measure what the public wants in a particular policy area and then correctly match it to policy in that area. This is difficult to do. Not surprisingly, while much scholarship examines the congruence of positions, little research examines actual policy congruence. Even the work that there is on the subject offers limited information. In this paper, I assess what we can infer about congruence from the different scholarly traditions in the study of representation. I also consider prospects for research on the match between public preference inputs and public policy outputs, particularly when we cannot assess it directly.
