Correcting misinformation about the Russia-Ukraine War reduces false beliefs but does not change views about the War

We report results from simultaneous experiments conducted in late 2022 in Belarus, Estonia, Kazakhstan, Russia and Ukraine. The experiments focus on fact-checking misinformation supportive of Russia in the Russia-Ukraine War. Meta-analysis makes clear that fact-checking misinformation reduces belief in pro-Kremlin false claims. Effects of fact-checks are not uniform across countries; our meta-analytic estimate is reliant on belief accuracy increases observed in Russia and Ukraine. While fact-checks improve belief accuracy, they do not change respondents’ attitudes about which side to support in the War. War does not render individuals hopelessly vulnerable to misinformation—but fact-checking misinformation is unlikely to change their views toward the conflict.
