A new report from Harvard Kennedy School’s Shorenstein Center on Media, Politics and Public Policy analyzes news coverage during the 2016 general election, and concludes that both Hillary Clinton and Donald Trump received coverage that was overwhelmingly negative in tone and extremely light on policy.

The negativity was not unique to the 2016 election cycle but instead part of a pattern in place since the 1980s and one that is not limited to election coverage. “A healthy dose of negativity is unquestionably a good thing,” writes Thomas Patterson, Bradlee Professor of Government and the Press, and the study’s author. “Yet an incessant stream of criticism has a corrosive effect. It needlessly erodes trust in political leaders and institutions and undermines confidence in government and policy,” resulting in a media environment full of false equivalencies that can mislead voters about the choices they face.

This is the final report of a multi-part research series analyzing news coverage of candidates and issues during the 2016 presidential election. The study tracks news coverage from the second week of August 2016 to the day before Election Day.
