More “balanced” thinkers (who were prone to frame arguments in “on the one hand” and “on the other” terms) were less overconfident (r = .37) and less in the limelight (r = .28). Of course, causality surely flows in both directions. On one hand, overconfident experts may be more quotable and attract more media attention. On the other, overconfident experts may also be more likely to seek out the attention.
