Why People Are So Confident When They’re Wrong

Veritasium explores the quirks of overconfidence—why we so often think we know more than we do. You’ll see how the Dunning-Kruger effect really works, discover brain shortcuts that trick us into certainty, and hear wild examples like Nick Leeson’s trading fiasco and the collapse of one of England’s oldest banks.

It’s not all bad news—overconfidence can fuel ambition, and with the right feedback loops (and even a new tabletop game on Kickstarter!), you can learn to spot your blind spots and make smarter decisions. Special thanks to Professors Moore and Fischhoff for the research that keeps our egos in check.
