NSF Convergence Accelerator Track F: Claiming that “skepticism regarding the integrity of U.S. elections and hesitancy related to COVID-19 vaccines are two consequences of a decline in confidence in basic political processes and core medical institutions” and that “social media serve as a major source of delegitimizing information about elections and vaccines, with networks of users actively sowing doubts about election integrity and vaccine efficacy, fueling the spread of misinformation,” this project aimed to “support and empower efforts by journalists, developers, and citizens to fact-check such misinformation” by developing tools to “enable testing of fact-checking stories on topics like elections and vaccines as they move across social media platforms like Twitter, Reddit, and Facebook, and deliver feedback on how well the corrections worked in real time and with full performance transparency.”

This was work to “develop an interactive system that enables fact-checkers to perform rapid-cycle testing of fact-checking messages and monitor their real-time performance among online communities at-risk of misinformation exposure.” It committed to sharing “all of the underlying code, surveys, and data” with the social science and computer science communities, and “all evidence-based messages of immediate utility to public health professionals and electoral administrators will be made publicly accessible.”
