Contributions
- Empirical evidence that corrections often fail to reduce political misperceptions, contrary to conventional assumptions
- Introduction and documentation of the "backfire effect" — the phenomenon that corrections can strengthen false beliefs among ideologically committed subjects
- Demonstration that correction effectiveness varies substantially by recipient ideology
- Realistic experimental design using mock news articles with embedded corrections, not abstract policy questions
Method
The authors conducted four experiments in which college-educated participants read mock news articles containing either a misleading political claim or a correction to that claim. The experiments tested three hypotheses:
- Ideological Interaction: The effect of corrections on misperceptions will be moderated by ideology
- Resistance to Corrections: Corrections will fail to reduce misperceptions among ideological subgroups likely to hold those misperceptions
- Correction Backfire: In some cases, corrections will increase misperceptions for ideologically committed subjects
Experiments focused on contemporary U.S. political controversies: Iraqi weapons of mass destruction (Study 1), stem cell research policy (Study 2), and tax policy effects on revenue (Studies 2–3). Participants were randomly assigned to read articles with or without corrections, and ideology was measured using self-placement on a seven-point scale. The dependent variable was a five-point Likert-scale measure of agreement with the misperception.
Results
- Overall correction effect: Corrections failed to reduce misperceptions across multiple political issues and showed no significant main effect
- Ideological moderation: The interaction between correction and ideology was statistically significant, indicating that correction effectiveness depends heavily on the recipient's political worldview
- Backfire among conservatives: On the Iraqi WMD question, corrections actually increased agreement with the misperception among conservative subjects
- Ideological asymmetry: Results differed by issue, with some backfire effects appearing only for conservatives and others for liberals, suggesting the effect is not uniformly partisan
- Knowledge as moderator: Political knowledge did not meaningfully reduce backfire effects
The findings suggest that motivated reasoning and defensive processing — whereby individuals resist information that contradicts their worldview — play a significant role in sustaining political misperceptions despite corrective information.
Notes
This paper is widely recognized as a cornerstone of misinformation research and introduced the "backfire effect" to mainstream academic attention, though subsequent work has debated the robustness and generalizability of the backfire finding. The paper's realistic design using actual news articles rather than abstract claims was methodologically novel for its time and set a standard for studying corrections in context. The ideological moderation finding — that corrections work differently across the political spectrum — remains empirically robust and theoretically important, even as the specific "backfire" phenomenon has been questioned in later replications and meta-analyses.
