VoxEU – Fighting misinformation with truth: Why mainstream news matters on social media
How can misinformation on social media be countered in the age of AI-generated content? This column uses an experiment conducted during the 2024 US presidential campaign involving 10,000 users of X to demonstrate that nudging users to think before sharing content can outperform fact-checking interventions in reducing misinformation. The experiment also reveals that users often struggle to distinguish true from false news, and that interventions are substantially more effective when users are exposed to ‘uncontroversial’ true news that they can reliably distinguish from false content. These findings suggest that fighting misinformation is not only about slowing the spread of falsehoods but also about ensuring the supply and visibility of credible information.

VoxEU – Evaluating anti-misinformation policies on social media
The prevalence of false political news on platforms like Facebook and Twitter highlights the potential for social media to spread misinformation. This column uses an experiment during the 2022 US mid-term election campaign to assess the impact of various policies on the circulation of accurate and false news on X (formerly Twitter). Warning users about the prevalence of false news before they retweet a message is most effective at reducing the sharing of false news and increasing the sharing of true news, without diminishing overall user engagement. The authors also find that rapid algorithmic fact-checking, despite being error-prone, is more effective than accurate but expensive and slower professional fact-checking.
