Meta-Analysis Shows Media Literacy Interventions Improve Resilience to Misinformation

The widespread dissemination of misinformation has become a global concern.

A recommended solution is to improve people’s ability to discern true from false information through appropriate media literacy education programs. This meta-analysis quantitatively synthesized the results of 49 experimental studies(N = 81,155) that examined the efficacy of media literacy interventions in mitigating misinformation. This study finds that media literacy interventions generally improve resilience to misinformation (d = 0.60). Specifically, the interventions reduce belief in misinformation (d = 0.27), improve misinformation discernment (d = 0.76), and decrease misinformation sharing (d = 1.04). Moreover, media literacy interventions have stronger effects (1) when multiple sessions rather than a single session are implemented, (2) in high (vs. low) uncertainty avoidance cultures, and (3) among college students than among adults recruited from online crowdsourcing platforms (e.g., Amazon Mechanical Turk).
