Debunking and exposing misinformation among fringe communities: Testing source exposure and debunking anti-Ukrainian misinformation among German fringe communities

Abstract

Through an online field experiment, we test traditional and novel counter-misinformation strategies among fringe communities. Though generally effective, traditional strategies have not been tested in fringe communities, and do not address the online infrastructure of misinformation sources supporting such consumption. Instead, we propose to activate source criticism by exposing sources’ unreliability. Based on a snowball sampling of German fringe communities on Facebook, we test if debunking and source exposure reduce groups’ consumption levels of two popular misinformation sources. Results support a proactively engaging counter-misinformation approach to reduce consumption of misinformation sources.
