Conventional wisdom suggests that judicial legitimacy should be relatively unaffected by satisfaction with the ideological direction of judicial policy making. Recent studies challenge this assertion. The key to resolving this conundrum is estimating individual-level satisfaction with the ideological direction of judicial policy making reliably and validly. We examine the accuracy of several common measures of the concept. We find that 40% of the respondents repudiate their own scores on these measures. With this much systematic measurement error in such an important independent variable, the question of whether the Supreme Court’s institutional legitimacy is conditional on ideological agreement with its decisions must be reexamined.
We greatly appreciate the support of Steve Smith and the Weidenbaum Center for this research. This project was made possible by a grant from TESS: Time-Sharing Experiments for the Social Sciences (NSF grant 0818839), Jeremy Freese and James Druckman principal investigators, to whom we are much indebted. We also acknowledge the assistance of Patrick Tucker in preparing the data we use for analysis, and we appreciate the comments of Pamela Corley, Chris Fariss, Charles Crabtree, Deborah Beim, Markus Neumann, Jeffrey Ziegler, and Miguel Maria Pereira on an earlier version of portions of this analysis.
