Boosting Media Literacy Using Lateral Reading and Online Search Interventions
Abstract
Empowering people to navigate online information competently is essential to complement systemic content moderation and platform regulation. A nationally representative randomized controlled study among adults in Germany ( N = 2,666) compared two media-literacy interventions: a source-focused lateral-reading strategy to help participants distinguish trustworthy from untrustworthy news outlets, and a claim-focused search strategy to help them assess the credibility of specific claims. Both interventions showed small improvements in discernment, but not all effects were statistically distinguishable from zero. At a 2-week follow-up, discernment improved in all groups, and differences between the intervention and control groups were no longer statistically distinguishable. We found no evidence of backfire effects. An exploratory analysis of discernment pretreatment indicated the lowest performance for supporters of populist radical-right parties. Behavioral measures suggested increases in information search in both intervention groups. On average, lateral reading reduced trust in untrustworthy sources, and online search increased trust in trustworthy sources.
