Introduction

Political knowledge is one of the primary variables in political communication research. In the United States, as well as other democratic nations, the study of political knowledge is rooted in democratic theory, which suggests that citizens should be informed if they are to participate in a democratic society. Political knowledge is also sometimes referred to as political sophistication or political expertise, but knowledge is generally defined as holding correct information—whether that is civic, issue, or candidate information, or the structural relationships among cognitions. Scholars often examine political knowledge as a dependent variable—for example, by examining media effects on political knowledge—but knowledge can also be examined as a predictor, moderator, or mediator in a variety of communication relationships. In this sense, political knowledge may lead to political discussion, or it may moderate the relationship between media use and political participation. However, just as general knowledge cannot be directly measured—rather, it is assessed via test scores or grades—political knowledge is directly immeasurable. In other words, the content of political knowledge, generally, cannot be fully captured in a series of test questions. For that reason, scholars often conceptualize political knowledge in varying ways. However, scholars have come to agree on some measures of political knowledge as good representations of the information citizens must have to participate fully in a democracy society.

Data Sources

A number of organizations regularly test political knowledge among Americans. The following sources measure several variations of political knowledge (see Conceptualizations) as well as variables commonly found in studies of media effects and political communication, such as media use and political participation. For data over several decades with the same measurement, scholars often turn to the American National Election Studies. For more detailed and variable measurements of knowledge, the National Annenberg Election Survey and Pew Research Center offer a variety of publicly available datasets.
