Overconfidence isn’t just ego—it’s a cognitive trick that makes us think we know way more than we do. Veritasium dives into the real Dunning-Kruger curve, reveals how our brains take lazy shortcuts that boost our certainty, and shares jaw-dropping tales—from rogue trader Nick Leeson to the crash of one of England’s oldest banks—to show how dangerous it can get.
But fear not, you can train your reality check. By casually asking “How confident are you?” and seeking honest feedback, you can dial down your blind spots. There’s even a new tabletop game on Kickstarter designed to help you curb your overconfidence while having fun. Play smarter, not harder.
