Why People Are So Confident When They’re Wrong
Overconfidence is one of the most dangerous cognitive biases because our brains love shortcuts, tricking us into believing we know more than we do. In this video Derek Muller and his team dive into the real Dunning-Kruger graph, show how mental heuristics inflate our certainty, and even explain why a little bit of overconfidence can sometimes be useful.
They back it up with wild case studies—from rogue trader Nick Leeson to the collapse of one of England’s oldest banks—and stress the lifesaving power of honest feedback. Finally, you’ll get practical tips (and even a Kickstarter tabletop game) designed to help you spot and correct your own overconfidence before it leads you astray.
