Early morning, April 1789. Captain Bligh is abruptly dragged from his cabin. Wrists bound, bayonet pressed to his chest, he and a few loyal sailors are forced into a tiny launch and set adrift on the vast Pacific Ocean. This far from land, no-one is likely to survive for long. History remembers Captain Bligh as a cruel, petty tyrant. The reality is more complicated. Bligh championed rational thought and showed his men great kindness on that famous voyage on the Bounty - yet it ended in mutiny. So what went wrong? This is the third episode in a four-part series about fairness. It's based on David Bodanis' excellent book The Art of Fairness: The Power of Decency In A World Turned Mean.

Paul Starrett has just won a major building contract. If everything goes according to plan, this will be the tallest building in the world. But will everything go according to plan? This prestigious new project will have Starrett's biggest workforce yet. Everyone will need to pull together, but labour relations in the United States have been rough. There have been tens of thousands of strikes in recent years, many ending in shootings and arbitrary mass arrests. Something else is bothering Starrett too: enormous steel-framed buildings normally take three or four years to complete. The deadline on this one? Just thirteen months. This is the second episode in a four-part series about how to succeed without being a jerk. It's based on David Bodanis' excellent book The Art of Fairness: The Power of Decency in a World Turned Mean. For a full list of sources, see the show notes at timharford.com.

Leo Durocher would stop at nothing to win. The baseball player-turned-manager was a skilled tactician and famously tough. But he also cheated, intimidated umpires and was violent; he was even known to beat up fans. Durocher was famous for coining the phrase "nice guys finish last" - but is that really true? Tim Harford and David Bodanis examine lessons from the life of a ruthless, pugnacious baseball star. This is the first episode of a four-part series about how to succeed without being a jerk. It's based on David's book The Art of Fairness: The Power of Decency in a World Turned Mean. For a full list of sources, see the show notes at timharford.com.

Young doctor Jesse Lazear has deadly Yellow Fever. He thrashes around and convulses in his sick bed, and his vomit is black. He is just 34 when he dies. Curiously, mosquito expert Lazear was researching the disease when he became ill. Some historians think his infection wasn't an accident, and that he was secretly experimenting on himself... Today, human challenge trials - where volunteers are intentionally given a disease under the watchful eye of medical support - are rare. The authorities are wary of the risks involved. But such trials can also mean that vaccines are developed faster and thousands of lives are saved. Is it time to start thinking differently about experimenting on humans?

Cautionary Conversation: Steve Jobs hated his phone so much that he smashed it against a wall. He also referred to mobile carriers as "orifices". Yet he went on to invent the world's most popular smartphone. Why did he change his mind? Tim Harford and organizational psychologist Adam Grant (Think Again, Hidden Potential) discuss the consequences of letting our ideas become part of our identity; when it's essential to adapt; and whether frogs really do stay sitting in slowly boiling water.

Panic has erupted in the cockpit of Air France Flight 447. The pilots are convinced they’ve lost control of the plane. It’s lurching violently. Then, it begins plummeting from the sky at breakneck speed, careening towards catastrophe. The pilots are sure they’re done-for. Only, they haven’t lost control of the aircraft at all: one simple manoeuvre could avoid disaster… In the age of artificial intelligence, we often compare humans and computers, asking ourselves which is “better”. But is this even the right question? The case of Air France Flight 447 suggests it isn't - and that the consequences of asking the wrong question are disastrous.

Until the 1960s, it was deemed too "dangerous" for women athletes to run distances longer than 200m - and a marathon would kill them, or leave them unable to have children. Rubbish, of course. But when Kathrine Switzer signed up for the 1967 Boston Marathon, it wasn't the distance that bothered her - it was the enraged race director trying to assault her. Thanks to pioneers like Kathrine, women have made huge strides in long distance running - and are now challenging the times of men in the very races they were banned from for so very long.

Adi and Rudi Dassler made sports shoes together - until a feud erupted between them. They set up competing companies, Adidas and Puma, and their bitter rivalry divided the sporting world, their family and even the inhabitants of their home town. The Dassler clan turned bickering into an art form - even drawing the likes of soccer legend Pele into their dispute. But did the brilliant fires of hatred produce two world-class companies, or was it a needless distraction from the Dasslers' love for their craft?

In the middle of the Pacific Ocean, in 1819, Owen Chase is standing on a slowly sinking ship. It's just been headbutted by an 85 foot whale. It's taking in water. And now the creature is coming back for another go. This is a whaling ship, and Chase is convinced that he observes "fury and vengeance" in the animal. In 2010, an orca is performing for a crowd at SeaWorld - but he misses his mark and so he doesn't get his reward. That's when he grabs hold of his trainer, Dawn Brancheau, and pulls her under water. By the time he's finished, her savaged body has multiple fractures and dislocations. And her scalp has been ripped off. To some observers, these whales were surely out for revenge. But how much is what we think we understand about the natural world shaped by human guilt? For a full list of sources, see the show notes at timharford.com.

Neatly dressed in his suit, Hans Ferdinand Mayer was every inch the unassuming corporate executive. So, when he asked to borrow a typewriter from his hotel in Oslo, nobody could have guessed he would use it for one of the most extraordinary intelligence leaks in history. Mayer's gloved fingers punched out the details of Nazi Germany's most sensitive military operations and, when he had finished, he immediately dispatched his documents to the British — who did nothing. Why did the British ignore Mayer? Did they fail to pick out a crucial signal amid the noise of detail — or was something else going on? This episode of Cautionary Tales is based, with permission, on Tom Whipple’s book The Battle of the Beams, which is available from all good booksellers.

Sam Israel had a problem. The investors in his hedge fund, Bayou Capital, were expecting spectacular returns. Sam himself had spent years proclaiming the fund's brilliant results. But in reality, Sam had been marking his own homework, publishing fraudulent accounts and using these to lure in new investors. What to do? Well, the logical thing of course: wait around for an extraordinary profitable streak, and in the meantime keep up the ruse... This episode of Cautionary Tales was recorded live at the Bristol Festival of Economics and studies three incredible investment scams. How do pyramid and ponzi schemes snowball out of control, flattening victim and fraudster alike? For a full list of sources, see the show notes at timharford.com.

Nicolae Ceaușescu was not beloved. His regime was vicious and he treated Romania as his personal wallet: while Ceaușescu emptied the coffers to construct a vast, ornate palace, his people starved. He imposed disastrous population control policies on his country, too, which saw hundreds of thousands of unwanted children left to rot in squalid orphanages. Ceaușescu's rule endured for a quarter of a century - then crumbled overnight. How do dictatorships unravel? In a second episode, Tim Harford partners with HBO's new series "The Regime" to investigate real-life dictatorships and the social science that explains them.

Why are so many autocrats germaphobes? Why was the truth so dangerous for Soviet engineers? And what can salami reveal to us about the mind of Vladimir Putin? This is the first of two special episodes in partnership with HBO's new series "The Regime". Tim Harford investigates real-life dictatorships and the social science that explains them, drawing on insights from game theory and psychology.

Chuck Yeager's plane pitched and rolled as it plummeted from the sky. He grappled with the controls inside the cockpit, but to no avail: he couldn't steady the aircraft. The test pilot was known for his nerves of steel but, as the barren Mojave Desert hurtled towards him, even he was afraid. What to do? It's tempting to think that adding to our lives - more action, more work, more possessions - will lead to greater success and happiness. But sometimes doing less is the better option, as Chuck Yeager was to learn the hard way. In their second crossover episode, Tim Harford teams up with Dr Laurie Santos (host of The Happiness Lab) to examine why subtraction can be so challenging and so helpful.

As US troops approached a Nazi prison camp, they could hear agonized wailing. The stench of rotting flesh filled their nostrils. Moments later they discovered a pile of smoldering corpses, alongside emaciated survivors. Next to the concentration camp they found something else: tunnels filled with tools — and partially assembled rockets. The soldiers had hit upon the evil heart of the V2 manufacturing program: enslaved laborers, imprisoned underground. And the rocket program's director? Wernher von Braun had already fled. He now had just one concern: persuading the Americans to let him switch sides… For a full list of sources, see the show notes at timharford.com. Do you have a question for Tim?

In the 1920s, Germany’s Society for Spaceship Travel boasted some of the sharpest scientific minds – like the incandescently brilliant young Wernher von Braun. But it had very little money, and progress was slow. Then, in 1932, the army made a proposal: it would fund more serious research if the enthusiasts at the Society would develop a rocket weapon. Despite a string of failures to launch, von Braun was able to convince key powerbrokers in Nazi Germany that they couldn’t afford to ignore rocket technology. How did he do it? And what happened when the murderous Heinrich Himmler made a play for the rocket program? For a full list of sources for this episode, visit timharford.com. Do you have a question for Tim?

At the height of World War Two, British intelligence began receiving reports that the enemy was developing a rocket weapon. The idea seemed fantastical — resources in Nazi Germany were scarce and a rocket-building program defied economic logic. But one intelligence chief took the reports of a rocket weapon seriously and he managed to convince Winston Churchill to heed the threat too. The British Prime Minister gave the order to bomb Germany’s rocket factory to rubble, and 600 bomber planes embarked on a full-scale attempt to obliterate it. From the air, the damage appeared devastating. The British thought they had succeeded in crushing the rocket-building program. But they were wrong.
