Replication Data for: Measuring Subjective Ideological Disagreement With the U.S. Supreme Court

Conventional wisdom suggests that judicial legitimacy should be relatively unaffected by satisfaction with the ideological direction of judicial policymaking. Recent studies challenge this assertion. Key to resolving this conundrum is estimating individual-level satisfaction with the ideological direction of judicial policymaking 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 re-examined.
