Representation theory obliges representatives to be responsive toward citizens’ wishes and demands between elections. Responsiveness is crucial because it provides citizens with a mechanism to control representatives beyond Election Day (Dahl, 1971; Mansbridge, 2003; Pitkin, 1967; Powell, 2004). This article addresses the subjective side of responsiveness processes: the extent to which citizens believe that representatives are indeed sensitive to their wishes and demands. Focusing on both conceptualization and measurement, we examine how survey researchers study responsiveness beliefs. Are current practices adequate, or is there room for improvement?
