Confidence in a specific judgment may help people identify misinformation. A new study found that decision-specific confidence was linked to greater accuracy when evaluating news headlines. In Science X / Phys.org: https://ow.ly/EXGW50ZmInm In PNAS Nexus: https://ow.ly/FFSC50ZmImS

Shown in the top graph is the average perceived accuracy rating of true and false headlines as a function of the participant's confidence in that specific accuracy judgment, relative to the user's average confidence across headlines; and, on the bottom, the participant's confidence in their general abilities. Error bars indicate 95% confidence intervals clustered on subject and headline.
