Citizens, Knowledge, and the Information Environment

Political knowledge influences a wide array of political behaviors, from the most elemental activities (e.g., information processing, opinion formation) to what some might consider the most fundamental (e.g., support for democratic values, participation). Yet, we know little about how people become informed. My research explores an important but understudied influence on knowledge: the information people are exposed to in the mass media. Using a series of surveys that are unique to the Roper Center, my collaborators and I examine political knowledge across dozens of topics over a period of nearly 25 years. These questions share an important characteristic: they query respondents about recent political developments. Knowing the correct answer to these “surveillance issues” depends almost exclusively on recent exposure to information in the media rather than learning that might have occurred years ago (e.g., in a high school civics class).

We estimate the nature of media influence by combining more than 50 Roper surveys with media content analysis data. Drawing upon a variety of approaches (e.g.,  within-subject comparisons, multi-level models), this research will provide new insight into the characteristics of media coverage—e.g., the number of stories, the use of expert sources, the prevalence of contextual coverage—that influence how people learn about politics. As such, it extends past studies, which have tended to focus on largely static, individual-level predictors of knowledge such as a person’s race, gender, or level of education.
