Why We’re So Sure—and So Wrong
In this Veritasium dive, Derek Muller unpacks our most dangerous cognitive bias: overconfidence. He breaks down the real Dunning-Kruger curve, reveals how our brains take mental shortcuts, and shares cautionary tales—like the rogue trader Nick Leeson and the collapse of a centuries-old English bank—to show why we so often mistake certainty for truth.
But it’s not all doom and gloom. Derek highlights how a dash of confidence can actually boost performance and offers solid feedback-based strategies to recalibrate your self-assessment. Plus, he introduces a fun tabletop game to test your certainty in real time—because sometimes the best way to learn you’re wrong is to play for it.
