Category: Career Growth, Workplace & Company Culture, Culture & Society
Why do smart groups make such dumb decisions? Sam and Sophie open with the Tenerife air disaster, where a legendary pilot's mistake killed 583 people because no one dared to question him.
They walk through Matthew Syed's core argument: cognitive diversity matters more than IQ. The episode covers the Cambridge spies, Moneyball, and a hospital that cut infections just by letting nurses speak up. Syed's framework includes rebel ideas, psychological safety, and recombining insights from different fields.
If you've ever been in a meeting where everyone nodded along to a bad idea, this episode names why that happens and how to fix it. The takeaway: the smartest system isn't the one with the highest IQ, but the one with the greatest diversity of thought.
