Do Policy Messengers Matter? Majority Opinion Writers as Policy Cues in Public Agreement with Supreme Court Decisions.

Does the identity of a majority opinion writer affect the level of agreement a Supreme Court decision receives from the public? Using a survey experiment, we manipulate majority opinion authors to investigate whether individuals are willing to agree with Supreme Court opinions authored by ideologically similar justices even though the decisions cut against their self-identified ideological policy preferences. Our study provides insight into the extent to which policy cues—represented by a political institution’s policy messenger—affect agreement with a given policy. We find that a messenger effect indeed augments the level of agreement a given Supreme Court case receives. [ABSTRACT FROM PUBLISHER]
