Debunking Study Suggests Ways to Counter Misinformation and Correct ‘Fake News’

News release: “It’s no use simply telling people they have their facts wrong. To be more effective at correcting misinformation in news accounts and intentionally misleading “fake news,” you need to provide a detailed counter-message with new information – and get your audience to help develop a new narrative. Those are some takeaways from an extensive new meta-analysis [fee req’d] of laboratory debunking studies published in the journal Psychological Science. The analysis, the first conducted with this collection of debunking data, finds that a detailed counter-message is better at persuading people to change their minds than merely labeling misinformation as wrong. But even after a detailed debunking, misinformation still can be hard to eliminate, the study finds. “The effect of misinformation is very strong,” said co-author Dolores Albarracín, professor of psychology at the University of Illinois at Urbana-Champaign. “When you present it, people buy it. But we also asked whether we are able to correct for misinformation. Generally, some degree of correction is possible but it’s very difficult to completely correct…” “Debunking: A Meta-Analysis of the Psychological Efficacy of Messages Countering Misinformation” was conducted by researchers at the Social Action Lab at the University of Illinois at Urbana-Champaign and at the Annenberg Public Policy Center of the University of Pennsylvania. The teams sought “to understand the factors underlying effective messages to counter attitudes and beliefs based on misinformation.” To do that, they examined 20 experiments in eight research reports involving 6,878 participants and 52 independent samples. The analyzed studies, published from 1994 to 2015, focused on false social and political news accounts, including misinformation in reports of robberies; investigations of a warehouse fire and traffic accident; the supposed existence of “death panels” in the 2010 Affordable Care Act; positions of political candidates on Medicaid; and a report on whether a candidate had received donations from a convicted felon. The researchers coded and analyzed the results of the experiments across the different studies and measured the effect of presenting misinformation, the effect of debunking, and the persistence of misinformation.”
