Why People Are So Confident When They’re Wrong

This Veritasium video dives into overconfidence, unpacking the Dunning-Kruger effect and showing how our brains take shortcuts that make us feel smarter than we are. You’ll see the “real” overconfidence graph, learn why a little hubris can sometimes be a good thing, and how clear feedback helps keep our ego in check.

Through wild case studies—like Nick Leeson’s rogue trades and the collapse of one of England’s oldest banks—we get a front-row seat to the dangers of unchecked certainty. And don’t worry, you’ll walk away with tips (and even a tabletop game) to recalibrate your confidence, invite honest criticism, and make better calls next time.
