We tell our children unsettling fairy tales to teach them valuable lessons, but these Cautionary Tales are for the education of the grown ups – and they are all true. Tim Harford (Financial Times, BBC, author of “The Data Detective”) brings you stories of awful human error, tragic catastrophes, and hilarious fiascos. They'll delight you, scare you, but also make you wiser. New episodes every Friday.

"What a Bloody Mess we're in" - Britain's [REDACTED] Accident

Jul 17th, 2026 7:01 AM

Windscale is supposed to be Britain's big leap into the nuclear age, bringing science fiction to life in 1950s Northern England. But in the race to catch up with America's nuclear program, scientists are tinkering with forces they don't fully understand. When the reactor catches fire, no-one knows how bad it could be, or how to put it out. As the reactor workers scramble to save lives, other eyes on Windscale are much more concerned with containing the political fallout and burying the truth.

Attack of the Night People

Jul 10th, 2026 4:01 AM

If you tuned in to late-night WOR radio in 1950s New York, you'd enter the secret world of Jean Shepherd. Shepherd's nonconformist style, off-beat humor and love of pranks gathered a small but loyal following. These "Night People" loved being in on the joke, while the oblivious "Day People" were often the butt of it. Shepherd's show is long gone, but his spirit lives on in corners of the internet. Today, though, Night People go by a different name. For a list of sources, see the show notes at timharford.com.See omnystudio.com/listener for privacy information.

LIVE: We Are Not Machines - with Sarah O'Connor

Jul 3rd, 2026 4:01 AM

When the Luddites smashed factory frames in a bid to defend their craft and livelihoods, the machines came out on top. Today, AI and automation threaten to wipe out skilled jobs and flood us with inferior products at a fraction of the price: is history going to repeat itself? FT journalist and author of We Are Not Machines Sarah O'Connor joins Tim to discuss her findings from the front lines about the future of work. Which professions are most at risk, and is there anything workers can do about it?

Treacle Tears: The Boston Molasses Disaster

Jun 26th, 2026 4:01 AM

The children of North End, Boston, play in the shadow of an enormous steel tank of molasses. The thick, sticky sugar syrup is being used to make munitions for the First World War. When a worker notices dark molasses seeping from the tank he warns the company that there could be a leak. But the man in charge, Arthur Jell, has more important things to worry about: schedules to meet and profits to make. Besides, it's only sugar. How dangerous could it be?

The Thief, the Jewels, and the Dublin Castle Conspiracy

Jun 19th, 2026 4:01 AM

In the early 1900s, Sir Arthur Vickers keeps the magnificent Irish Crown Jewels safe under lock and key at Dublin Castle. When the jewels disappear, the King rages, the police investigate, and even Sir Arthur Conan Doyle gets involved. No one is ever charged and no jewels are ever recovered. Except, we have a very good idea of who took them, and why the truth has stayed buried.
