Political radicals don’t evaluate their own errors–about anything (2018)

A new study pins the blame on a faulty metacognition, the process by which people recognize when their ideas might not be correct and update their beliefs accordingly. To spot the radicals, all participants were given a set of questions about their beliefs on a variety of topics, designed to get at things like their dogmatism, intolerance, and authoritarian tendencies. And, informatively, people with radical beliefs were less likely to update their confidence in response to the additional information, a feature that the authors consider a defect specific to metacognition.
