Cautionary Tales with Tim Harford

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 other Friday.


How the Radium Girls Fought Back
Cautionary Book Club: Mollie Maggia's dentist planned to remove a painful abscess from her mouth. But to his horror, her jawbone disintegrated at his touch, crumbling and splintering until it resembled ash. Like hundreds of her colleagues, Mollie had been slowly poisoned by her work with glowing radium dust. Eight months after her first toothache, she was dead. In the previous episode, Cautionary Tales told the story of the "Radium Girls". Their employers ignored the horrific side effects of these women's work, resorting to obfuscation and even outright lies to deny their claims that they were getting sick. In this follow-up interview, Tim Harford sits down with Kate Moore, author of The Radium Girls: The Dark Story of America's Shining Women. Tim and Kate discuss how the women banded together and worked out what was happening to them, as well as how they fought back against their powerful bosses and their monumental legacy.See for privacy information.

Glowing Peril: The Magical Glitter That Poisoned a City
In Goiânia, Brazil, a junk dealer acquires an old medical device from two scrap-metal scavengers. The device itself isn't useful, but it comes with precious lead which will fetch him good money. There's something else inside the device, too: a curious, crystal-like substance that glows bright blue in the dark. At first, the dealer is mesmerized by it: he wants to turn it into jewelry for his wife. But, everyone who comes into contact with the magical glitter seems to get sick. His own family succumbs to nausea and vomiting. A doctor suggests food poisoning - but this isn't like any food poisoning they've ever known before. And soon, the whole city is contaminated. No-one saw this horrifying radiation accident coming. Should they have? For a full list of sources, please see the show notes at for privacy information.

George Washington's Beard of Beetles (with The Dollop)
Cautionary Conversation: Just before Christmas 1799, President George Washington was riding around his country estate, Mount Vernon, when it began to snow. When he arrived home, guests were waiting for him. Known for his punctuality, he hurried to entertain them -  still clad in his damp clothes. The next morning, Washington had a sore throat and a chesty cough. His family decided to take a fateful step: they summoned a doctor. Tim Harford is joined by comedians Dave Anthony and Gareth Reynolds, hosts of the hugely popular history podcast The Dollop. They discuss the parade of doctors that tended to the ailing Washington, and the various remedies they prescribed - from lamb's blood to a collar of beetles. Tim, Dave and Gareth also look at what happened when cars first hit the streets in the early twentieth century: why did so many cars "turn turtle"? Who were the first jaywalkers? And which British inventor rode around in a giant white stiletto?See for privacy information.

Laser Versus Parchment: Doomsday for the Disc
William the Conqueror undertook a remarkably modern project. In 1086, he began compiling and storing a detailed record of his realm: of where everyone lived, what they did and where they came from. 900 years later, the BBC began its own Domesday project, sending school children out to conduct a community survey and collect facts about Britain. This was a people’s database, two decades before Wikipedia. But just a few years later, that interactive digital database was totally unreadable, the information lost. We tend to take archives for granted — but preservation doesn't happen by accident; digitisation doesn’t mean that something will last forever. And the erasure of the historical record can have disastrous consequences for humanity... For a full list of sources, please see the show notes at for privacy information.

Oil and Blood: The Osage Murders

DOUBLE BILL: A Monkey For Mayor / A Screw Loose At 17,000 Feet
This week, we've twice the storytelling fun for you: two Cautionary Tales shorts, previously only available to Pushkin+ subscribers. A Monkey for Mayor: It was supposed to be a publicity stunt, but when the man who dressed as Hartlepool United’s monkey mascot stood in a mayoral election... he won. Actual politicians predicted disaster - since thousands of workers and millions of dollars were now in the hands of a complete novice. But H’Angus the Monkey proved to be a more effective leader than anyone had predicted, raising interesting questions about how we select the best people to be our managers and our mayors. And A Screw Loose At 17,000 Feet: Can you tell the difference between an A211-7D bolt and an A211-8C? Well, nor could the tired and stressed engineer fitting a cockpit windshield to Flight 5390. The difference is tiny, but the consequences of muddling them up - which played out at 17,000 ft - were dramatic. Such design flaws are common - and result in far more loose aircraft windows than you would imagine.See for privacy information.

The longest running television series of the 20th century was Gunsmoke, a western set in the notorious Dodge City, Kansas.

A Chorus of Contempt at The Sydney Opera House
1957. Jørn Utzon receives a phone call: he's just won an international competition to design a brand new opera house for the Australian city of Sydney. Utzon is unknown in the field, so this is a triumph. The young architect couldn’t have imagined what a bitter victory it would turn out to be... The Guggenheim in Bilbao; the Burj Khalifa in Dubai; the Shard in London. These days, everyone seems to want an iconic building. But Sydney Opera House was the first, the greatest – and the most painful. It's now fifty years since the Opera House was opened. This is its origin story.

The City That Sold Itself To Wall Street
Cautionary Book Club: When Morgan Stanley offered to lease Chicago's parking meters for the princely sum of $1 billion, the City Council were convinced that they had struck gold. They hastily signed the deal. But they soon learnt that they hadn't just traded away parking revenue - they had traded away the streets themselves... In this hybrid episode of Cautionary Tales, Tim Harford first tells the story of the Chicago parking metres fiasco of 2008. In the second half, Tim is joined by Henry Grabar, author of Paved Paradise, to discuss the lessons we can glean from Chicago's deal with Wall Street, and why parking is such an emotive issue for so many.See for privacy information.

General Ludd's Rage Against the Machines
1812. A band of "Luddites" is laying siege to a textile mill in the North of England, under cover of night. They plan to destroy the machines that are replacing their jobs. But mill owner William Cartwright is prepared: he's fortified his factory with skilled marksmen, fearsome eighteen-inch metal spikes and barrels of sulphuric acid. Today "Luddite" is a term of mockery — a description for someone who's scared of technology. But in 1812, Luddism was no laughing matter for the likes of Cartwright.

What happens next is a landmark event in the history of art and authenticity… Tim Harford is joined by Alice Sherwood, author of Authenticity, to discuss truth and fakery in modern times.

Poles Apart: How A Journalist Divided A City

Cook has a gripping manner and an excellent reputation: his winning tale must be true. Diners boo Gibbs at a restaurant, newspapers publish sly-looking caricatures of him, and he even receives threats of violence. But then, everything changes. We often think of polarisation as a modern problem — but the story of Cook and Gibbs has much to teach us here. For a full list of sources for this episode, please visit for privacy information.

A Fascination with Failure: Death On The Dancefloor (Classic)
Henry Petroski is one of Tim Harford's favourite fellow nerds. His study of engineering failures has profoundly influenced Tim's own writing, including the classic Cautionary Tales episode Death on the Dance Floor. Petroski passed away in June 2023, at the age of 81. This week, in honour of the late great engineer, Tim looks back at the catastrophic Kansas City Hyatt Regency disaster of 1981. The hotel's space-age sky walks -- 60 tonnes of glass, concrete and steel -- crashed down onto the heads of revellers in the atrium below. 114 people died. What was to blame?

The Coup, the Poet and the Secret to Winning Wimbledon
“If you can make one heap of all your winnings and risk it on one turn of pitch-and-toss..." Those words - from Rudyard Kipling's poem "If" - were based on charismatic nineteenth century doctor, Leander Starr Jameson. In Britain, Jameson was worshipped as a plucky hero: a bastion of courage and mental fortitude. Ironically, he was also responsible for the Jameson Raid, a South African coup that was an unmitigated disaster. Kipling's champion might have spearheaded a fiasco - but could the poem "If" hold clues for triumph in another arena?See for privacy information.

The Man Who Played With Hurricanes
Today, the idea of controlling the weather is controversial. Scientists who research geoengineering have even received death threats. But once upon a time, people were optimistic about remaking the climate in entire regions of the world. They approached this science with a touching faith in the power of human creativity. Absent-minded genius Irving Langmuir was one such scientist. He dreamt of making deserts bloom and conjuring rain from an arid sky. He even believed that his experiments with a hurricane had succeeded in redirecting its path. Why did we stop trying to control the weather? And might geoengineering help us solve climate change - or have we missed our chance? For a full list of sources, please visit for privacy information.

The True Scandal of Lydia E. Pinkham’s Vegetable Compound
It could cure any 'female ailment' - even cancer - said the adverts. But Lydia E. Pinkham’s Vegetable Compound was, in fact, just a concoction of herbs and alcohol of no proven medicinal merit. That didn't stop desperate American women from buying bottles of the stuff - and writing to Lydia Pinkham for medical advice.   Why did her customers shun 'expert' doctors and opt instead for quack medicines? And why, when Lydia Pinkham finally came in for criticism, did no one question the efficacy of her vegetable compound?   For a full list of sources for this episode, go to for privacy information.

What if Terrorists Could Weaponize Covid?

Air traffic controllers are meant to stop aircrafts from flying into one another... and if they fail, computer systems are installed to warn pilots of a coming collision. But sometimes these humans and computers give conflicting and confusing advice. Who to believe?

Office Hell: the Demise of the Playful Workspace
In the early 90s, cutting-edge advertising agency Chiat/Day announced a radical plan, aimed at giving the company a jolt of creative renewal. They would sweep away corner offices and cubicles and replace them with zany open spaces, as well as innovative portable computers and phones. A brand new era of “hot-desking” had arrived. Problems quickly began. Disgruntled employees found themselves hauling temperamental, clunky laptops and armfuls of paperwork all over the office; some even had to use the trunks of their cars as filing cabinets. Soon, the unhappy nomads had had enough. Bad execution was to blame for the failure of this “playful” workspace. But Chiat/Day had made another mistake here, too – one that was more serious, more fundamental and altogether more common.
