Why Confidence Can Be Dangerous

Two people give you advice. One admits uncertainty. The other speaks with total conviction. Most people instinctively trust the confident one — even though confidence tells you nothing about who's actually right. This video breaks down the real psychology of why confidence can be dangerous. We cover the actual Dunning-Kruger research (not the oversimplified meme version), including the lesser-known finding that highly skilled people tend to underestimate themselves, Cameron Anderson's research showing confidence gets mistaken for competence in group settings, and Daniel Kahneman's "illusion of validity." We also look at where this becomes genuinely consequential — in investing, leadership selection, and group decision-making — and what research says actually helps you tell justified confidence from unjustified certainty.
