The "Truth Decay Cascade": How Repeated Debunking Inadvertently Reinforces Misinformation

While Garimella et al. (2024) note that misinformation "frequently recirculates despite prior debunking," no study has examined whether the process of debunking itself contributes to this persistence. Drawing on the "illusory truth effect" (repeated exposure increases perceived truth), this research would track how repeated fact-checks of identical claims (e.g., election fraud narratives) alter belief accuracy across partisan groups. Unlike Wack et al. (2024), who focus on fact-checking speed, this idea examines frequency as a novel variable. Using longitudinal experiments, we’d test if exposure to multiple fact-checks of the same claim paradoxically increases perceived plausibility—especially when fact-checks use complex language (per Bachmann & Valenzuela’s 2023 findings on reduced media trust). This challenges the normative assumption that "more fact-checking = less misinformation" and could redesign debunking protocols to minimize repetition.
