Correcting campaign misinformation: Experimental evidence from a two-wave panel study

In this study, we used a two-wave panel and a real-world intervention during the 2017 UK general election to investigate whether fact-checking can reduce beliefs in an incorrect campaign claim, source effects, the duration of source effects, and how predispositions including political orientations and prior exposure condition them. We find correction effects in the short term only, but across different political divisions and various prior exposure levels. We discuss the significance of independent fact-checking sources and the UK partisan press in facilitating effects.
