Misinformation interventions¶
Interventions to reduce the creation, spread, and impact of misinformation. Approaches range from reactive (fact-checking, debunking, content moderation) to proactive (media literacy, psychological inoculation, pre-bunking). The effectiveness of interventions depends on timing (before vs. after exposure), mechanism (cognitive vs. emotional), and target population.
Categories of intervention¶
Reactive (post-exposure): - Fact-checking and corrections - Removal or labeling of false content - Debunking and explanation of how misinformation was made - Media literacy education
Proactive (pre-exposure): - Psychological inoculation against manipulation techniques - Pre-bunking through warnings about common tactics - Media literacy training in schools - Literacy campaigns
Systemic/platform-level: - Content moderation and removal policies - Amplification controls (reducing algorithmic boost) - Friction (friction delays, labeling) - Lateral reading tools
Effectiveness evidence¶
Most interventions show modest to moderate effects. Fact-checking reduces but does not eliminate the influence of misinformation. Pre-bunking and psychological inoculation are increasingly supported by empirical evidence as more scalable and effective than post-hoc debunking.

- Van der Linden (2026) — Bad News: Building Resilience to Misinformation Through Inoculation (video lecture) — detailed comparison of reactive fact-checking versus proactive psychological inoculation. Presents the Bad News game as a gamified intervention teaching six core manipulation techniques, with evidence of effectiveness across demographics and persistence over time. Covers large-scale deployments on YouTube and social media.
