Science says those who think they are experts are more likely to be closed-minded

Olivia Goldhill:

Those who count themselves as experts might want to re-evaluate their level of self-confidence, as a new study warns that there’s a downside to feeling knowledgeable.

Researchers led by Professor Victor Ottati from Loyola University of Chicago conducted six experiments on 272 participants in a study due to be published in the Journal of Experimental Social Psychology, and found that those who perceive themselves as experts tend to exhibit more closed-minded behavior.

Ottari and his colleagues hypothesize that social norms allow those who claim expertise to adopt a more closed-minded position.
“Because experts have already given extensive thought to issues within a domain, they have ‘earned’ the privilege of harboring more dogmatic opinions and beliefs,” write the authors.
