Social media can magnify health misinformation, especially about vaccination.1 Platform countermeasures have included censoring, shadowbanning (limiting distribution without disclosure), and adding warning labels to problematic content. Yet, evaluating these countermeasures is challenging due to restrictive public disclosures about their inner workings.2
In late 2022, X (formerly Twitter) introduced Community Notes, a crowdsourced misinformation countermeasure. Anonymous volunteer contributors independently identify posts containing misinformation and propose corrections called “notes.” Notes labeled as helpful by contributors who disagreed on past notes (to rely on a diversity of perspectives) are shown alongside the original post.3 Because Community Notes is open source, we were able to evaluate the topics, accuracy, and credibility of notes addressing COVID-19 vaccination.
