Covering the Court: The Impact of a Modern Era of Journalism 公开

Abstract

Public support is crucial to the institutional legitimacy of the U.S. Supreme Court. However, in recent years, public support for the Court has gone through periods of instability or decline. This dissertation presents a theory of how changes in the American media environment lead to changes in beliefs about the legitimacy of the Court among the American public. By presenting the Court as politicized, modern media undermine the Supreme Court's image as a neutral, unbiased arbiter of important societal disputes. Through elite interviewing and text analysis of an original dataset of over 100,000 news stories about the Supreme Court, I demonstrate that there are differences in the way that legacy and modern news sources produce news, leading to systematic variation in the information that the audiences of different news outlets receive about the Court. Thus, the types of coverage noted by both existing observational and experimental studies as detrimental to public support for the Court does exist, and it is growing more prevalent over time. These findings have important implications for the continuing authority of the Supreme Court and ultimately the rule of law in American society.
