Why People Are So Confident When They’re Wrong

We all love feeling sure of ourselves, but this video peels back the layers of overconfidence—aka the Dunning-Kruger effect—to show how our brain’s shortcuts trick us into thinking we know more than we do. Along the way, you’ll meet cautionary tales like Nick Leeson’s rogue trading fiasco and the collapse of one of England’s oldest banks, plus discover situations where a little swagger actually pays off.

More importantly, you’ll learn why honest feedback is your secret weapon, see what the real Dunning-Kruger graph looks like, and pick up practical tips for dialing down that misplaced certainty. And if you’re keen to practice staying humble, there’s even a new tabletop game on Kickstarter designed to keep overconfidence in check.
