The Most Dangerous Cognitive Bias

Derek Muller and Gabe Strong dive into why overconfidence is our brain’s sneakiest trap—from the classic Dunning-Kruger graph and mental shortcuts to real-world fiascos like Nick Leeson’s rogue trades and the collapse of one of England’s oldest banks. They show that while a dash of confidence can fuel ambition, unchecked swagger often leads to blind spots and big mistakes.

Teaming up with Professors Moore and Fischhoff, the video unpacks how feedback, reflection, and even a new tabletop game (now on Kickstarter) can help us curb that overconfidence. Plus, Derek shares bonus goodies like his Snatoms molecular kit, a weekly science newsletter, and full reference links for curious minds.
