Combatting Climate Disinformation: Comparing the Effectiveness of Correction Placement and Type

In this study, we investigated whether corrections can combat climate disinformation. Using a preregistered quota-based online experiment in Germany (N = 1401), we tested how the effectiveness of disinformation correction in reducing climate misperceptions was influenced by correction placement (prebunking or debunking) and correction type (focused on facts, logic, or the combination of both). We investigated how populist radical-right (PRR) attitudes moderate the effect of disinformation correction and whether correction alleviates the negative effects of disinformation on efficacy beliefs to mitigate climate change (EBMCC) through reduced misperceptions. All debunking conditions and the logic-focused prebunking condition significantly reduced climate misperceptions. Prebunking was only effective under the logic-focused correction condition. We found no moderating effect of PRR attitudes on climate misperceptions, suggesting that corrections similarly benefitted all participants. In addition, a significant indirect effect of corrections was observed on EBMCC via climate misperceptions.
