Epistemic confidence conditions the effectiveness of corrective cues against political misperceptions

Does epistemic confidence affect Americans’ willingness to defend misperceptions in the face of correction? Individuals with excessive confidence in their political knowledge are expected to resist the effects of corrective cues against political misperceptions. In this study, I assess the effects of confidence on skepticism towards five common political misperceptions in observational and experimental settings. In Study 1, I observationally assess the effects of epistemic confidence on resistance to corrective cues. In Study 2, I temper excessive confidence among a random subset of respondents using a specialized experimental treatment, before exposing them to a corrective cue. Together, the results show that corrections can reduce support for misperceptions among those with modest confidence. However, in the presence of excessive epistemic confidence, these treatments are ineffective. The present findings suggest that epistemic confidence complicates the work of fact-checkers and science communicators in modern democratic politics.
