There’s a reason we share scary stories-not just to entertain, but to learn. Cautionary Tales with Tim Harford applies that same instinct to the real world, digging into history’s most fascinating blunders and disasters to uncover what they can teach us today. Brought to you by Pushkin Industries, each episode feels like a masterfully told story, where Tim Harford-known for his work at the Financial Times, the BBC, and as author of “The Data Detective”-unpacks a single event. You’ll hear about catastrophic business decisions, scientific hubris, and public policy fiascos, all presented with a blend of narrative flair and sharp analysis. This isn’t just a history podcast; it’s a deep dive into human nature, decision-making, and the unexpected consequences that ripple from a single mistake. Listening feels like having a brilliantly insightful guide explain why things went so terribly, or hilariously, wrong. The stories are gripping on their own, but the real value lies in the lessons they make tangible for our own lives and choices. If you’ve ever wondered how a group of smart people could make a disastrous call, or how a seemingly small error snowballed into legend, this is the podcast for you.
