Title How Does Exposure to Online Partisan Media Affect Political Attitudes and Behavior?
Post date 11/14/2018
C1 Background and Explanation of Rationale Despite widespread concern about the effects of partisan media on important political outcomes, research in this area continues to be plagued by methodological and conceptual difficulties. We design and implement an online field experiment in the United States to study the effects of long-term exposure to partisan media in a real-world setting.
C2 What are the hypotheses to be tested? Numerous hypotheses are outlined in our PAP. These are primarily about direct effects and heterogeneous effects (by party and prior media consumption) on issue attitudes, agenda setting, downstream news consumption and social media behavior, and misperceptions.
C3 How will these hypotheses be tested? * We combine an encouragement design, embedded in a representative online panel survey, with logging of respondents’ web+mobile visit data and social media activity (public Twitter posts). Subjects in two treatment conditions are encouraged to change their browser homepage, follow the associated Facebook page, and sign up for email newsletters from one of two major media outlets (one treatment is a liberal site, one conservative). We collect outcomes in at least two follow-up survey waves and in linked behavioral data.
