As evidenced during the Covid-19 crisis, medical misinformation and false beliefs in alternative treatments may have dramatic consequences, especially among populations with low levels of digital literacy and education. This paper examines whether a sustained, classroom-based media and information literacy intervention can help school children in Bihar, India, to become more discerning consumers of public health information. Collaborating with a branch of Bihar's state government, we developed and fielded a multi-session media literacy RCT across 583 villages, targeting over 12,000 students. Unlike previous anti-misinformation interventions, this project focuses on rural populations, long-term engagement, and adolescents aged 13 to 18. Results from intent-to-treat estimates demonstrate that our intervention had significant impacts on a number of counts: treated students showed heightened ability to discern between true and false information. Notably the intervention also changed health preferences, diminishing reliance on alternative medical approaches and decreasing dependence on untrustworthy sources of news. We are able to detect effects up to 2 months post intervention, speaking to the strength of the treatment in changing attitudes long-term. These findings hold significant implications for assessing the efficacy of media literacy measures in light of previous studies that often yield null or mixed results. Our intervention demonstrates continued effectiveness among a particularly challenging sample and difficult context.
