A Meta-Analytic Examination of the Continued Influence of Misinformation in the Face of Correction: How Powerful Is It, Why Does It Happen, and How to Stop It?
A meta-analysis was conducted to examine the extent of continued influence of misinformation in the face of correction and the theoretical explanations of this phenomenon. Aggregation of results from 32 studies ( N = 6,527) revealed that, on average, correction does not entirely eliminate the effect of misinformation ( r = –.05, p = .045). Corrective messages were found to be more successful when they are coherent, consistent with the audience’s worldview, and delivered by the source of the misinformation itself. Corrections are less effective if the misinformation was attributed to a credible source, the misinformation has been repeated multiple times prior to correction, or when there was a time lag between the delivery of the misinformation and the correction. These findings are consistent with predictions based on theories of mental models and offer concrete recommendations for practitioners.

We just published a meta-analysis, where one finding is that "number of sickdays" is a bounded, not seldom zero/one-inflated variable, which is unsuitable for meta-analysis based on mean/SD. Today, I came across a meta-analysis including sickday stats like mean=9 and SD=27. doi.org/10.1186/s40359-026-05648-2

She identified a few and we contacted the authors to request their effect sizes and other variables for the studies in their papers.

The paper was retracted yesterday—here a little summary of the process.🧵
@bmj.com Please look at PubPeer comments on an article you published last week. pubpeer.com/publications/C08779C45DB6E407… I think your research integrity dept shld act swiftly on this one, given clinical significance. I'm aware of even more evidence of problems so let me know if this is not sufficient.
