This Veritasium episode dives into the perils of overconfidence by asking the deceptively simple question: “How sure are you that you’re right?” It unpacks why we all overestimate our abilities, shows the real Dunning-Kruger curve (spoiler: it’s not what you think), and explains how mental shortcuts leave us blind to our own ignorance.
Along the way, we meet cautionary tales like rogue trader Nick Leeson and the collapse of one of England’s oldest banks—both wrecked by unchecked certainty. The video wraps up with practical advice on seeking honest feedback, embracing uncertainty, and recalibrating your confidence so you can make smarter decisions.
