Knowledge Overconfidence and Anti-Consensus Views
Caveat: I am not a psychiatrist nor am I the physician treating the individuals discussed here. I am not trying to make diagnoses from online behavior or activity. I am only noting here that these specific behaviors align with specific enumerated traits as listed in the DSM-V. I cannot make a statement about these people individually.
People who think of themselves as brilliant heterodox thinkers are overcompensating for a significant mismatch between their objective and subjective knowledge.
That is to say, people who hold anti-consensus views have both an inadequate fund of knowledge on these particular topics and an unearned inflated view of their own expertise. In fact, the larger the gap between their actual fund of objective knowledge and their subjective assessment of their knowledge, the more strongly they hold anti-consensus views — the most extreme opponents are most likely to believe that their actual knowledge ranks among the highest, yet actually ranks among the lowest.
The authors of this 2022 article in Science Advances found that “increasing opposition to the consensus is associated with higher levels of knowledge confidence for several scientific issues but lower levels of actual knowledge.”
