Note: YouGov showed U.S. adult citizens a randomized set of 20 headlines — 10 of which were real and 10 of which were fake headlines — and asked people to say whether they believed each headline was real or fake. This survey design comes from the Misinformation Susceptibility Test (https://doi.org/10.3758/s13428-023-02124-2). Confidence in ability to spot fake news is based on responses to the question, "How confident are you that you can tell real news from fake news?"
