Extremists are more confident

Abstract Metacognitive mental states are about states. For example, I may be uncertain whether my belief is correct. In social discourse, an interlocutor’s metacognitive certainty constitute evidence the reliability of their testimony. if a speaker certain that correct, then we take this as in favour or its content. This paper argues that, genuine evidence, it disproportionate for extreme beliefs. support argument, report findings from five studies with different participant samples, designs, and measures. These show more agent’s (positive negative), they it, vice versa. relationship might contribute to moralism, virtue signalling, polarisation, which turn epistemically morally problematic. Therefore, caution against taking evidence.
