With time comes trust? The development of misinformation perceptions related to COVID-19 over a six-month period: Evidence from a five-wave panel survey study in the Netherlands

Abstract Misinformation perceptions related to global crises such as COVID-19 can have negative ramifications for democracy. Beliefs related to the prevalence of falsehoods may increase news avoidance or even vaccine hesitancy – a problematic context for successful interventions and policymaking. To explore how misinformation beliefs developed over a six-month pandemic period and how they corresponded to (digital) media preferences and selective exposure to the news, we rely on a five-wave panel survey conducted in the Netherlands (N =1,742). Our main findings show that misinformation perceptions got more pronounced as the pandemic evolved. Social media use related to more pronounced misinformation beliefs within waves, whereas mainstream news use corresponded to less pronounced misinformation beliefs. An important implication for journalists and policymakers is to lower the over-time accumulation of misinformation perceptions, for example, by increasing transparency and acknowledging “honest mistakes.”
