How to unring the bell: A meta-analytic approach to correction of misinformation
Abstract
The study reports on a meta-analysis of attempts to correct misinformation (k = 65). Results indicate that corrective messages have a moderate influence on belief in misinformation (r = .35); however, it is more difficult to correct for misinformation in the context of politics (r = .15) and marketing (r = .18) than health (r = .27). Correction of real-world misinformation is more challenging (r = .14), as opposed to constructed misinformation (r = .48). Rebuttals (r = .38) are more effective than forewarnings (r = .16), and appeals to coherence (r = .55) outperform fact-checking (r = .25), and appeals to credibility (r = .14).

“Further, the literature on source credibility suggests that messages delivered by a credible source are deemed more trustworthy compared to messages linked to low-credibility sources (Pornpitakpan, 2004); hence, corrective messages that leverage on source credibility are more likely to be effective.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
