Justice Speaks, but Who’s Listening? Mass Public Awareness of US Supreme Court Cases

We seek to measure the impact of decisions issued by the US Supreme Court on public awareness of its cases. We use a quasi-experimental design with the Court decisions as the stimulus of hypothesized public awareness change. We find that public awareness of cases varies according to individual differences: more educated, knowledgeable, and informationally motivated citizens are more likely to report awareness. Further, decision announcements increase awareness more generally, especially in cases of moderate salience. In contrast, for a very high salience case, awareness is high before and after the decision is announced, while, for a case fabricated by the investigators, “awareness” is not affected by the Court’s activities. The results suggest that while the public may eventually respond to the behavior of national institutions, this response is likely first filtered through an elite subset of the population.
