Latino-targeted misinformation and the power of factual corrections

Do individual, interpersonal, or institutional factors condition the effects of misinformation on beliefs? Can interventions such as fact checks stem the tide of the "infodemic" within marginalized communities? We explore the sudden flood of misinformation and disinformation targeting Latinos during the 2020 election and global COVID-19 pandemic to answer these questions. In a preregistered experiment, we find that exposure to misinformation can decrease factual accuracy, and neither trust in nor consumption of media, including ethnic media, serves as a buffer against these misinformation effects. However, fact checks eliminate the effects of misinformation on false beliefs without "backfiring" and reducing accuracy. Fact checks improve factual accuracy among subgroups varying in levels of political knowledge, trust, and acculturation. These findings provide crucial support for recent investments into fact checking by Latino-oriented media outlets and address gaps within the literature over whether such interventions are also effective within marginalized groups.
