Replication Data for: Calibrating Confidence: Civic Education and the Relationship Between Objective Political Knowledge and Political Knowledge Confidence

The concept of political knowledge is foundational to American politics, but we know little about the extent to which its two dimensions – objective knowledge and knowledge confidence – covary over time as citizens learn about the American political system. We employ a two-wave survey to study whether individuals gain both objective knowledge and knowledge confidence such that they calibrate over time when exposed to civic education coursework. We find students gain both objective knowledge and knowledge confidence over the semester and that, on average, the gap between them shrinks after taking Introduction to American Government. However, we also see evidence that a student’s initial levels of knowledge shape growth in these two concepts and whether they become more closely aligned over the semester. The results shed light on the relationship between what individuals know about politics and what they think they know and the role of civic education in shaping an active and informed electorate.
