Replication Data for: Inoculation Reduces Misinformation: Experimental Evidence from Multidimensional Interventions in Brazil

Misinformation is widely seen as a threat to democracy that should be promptly addressed by scholars, journalists, and policy-makers. However, some of the debated solutions are either controversial (internet platform regulation) or may be difficult and costly to implement in many settings (fact-checking corrections). This study investigates the effectiveness of preemptive interventions, a type of solution that has received considerably less attention in this debate. Studies show that interventions through awareness and media literacy campaigns can inoculate citizens against mis- information, but these interventions are restricted to a few contexts and settings. Our paper uses two field experiments, one of which conducted in partnership with Brazil’s main newspaper, to investigate the effectiveness of a multidimensional in- tervention against misinformation in São Paulo. The findings show that preemptive interventions can indeed reduce rumor acceptance and provide insights into the strategies to combat misinformation in democracies.
