Futureproof Gold: Chances
Summary
Jonathan McCrea explores the mathematics of coincidence with statistician Michael Salter-Dowsend, who deconstructs listener-submitted stories to reveal their true probabilities. By analyzing cases like a man finding a stranger’s wallet after meeting him on a flight, the episode demonstrates how humans often overestimate the rarity of events due to cognitive biases. The discussion highlights the dangers of misinterpreting odds, referencing the wrongful conviction of Sally Clark, and concludes that while specific sequences are unlikely, coincidences are far more common than intuition suggests.
