The Inventor Who Almost Ended the World
Thomas Midgley's inventions caused his own death, hastened the deaths of millions of people around the world, and very nearly extinguished all life on land. Midgley and his employers didn't set out to poison the air with leaded gasoline or wreck the ozone layer with CFCs - but while these dire consequences were unintended... could they have been anticipated?

The Halloween Poisoner
Candy laced with cyanide and needles in marshmallows, we've long been warned to be suspicious of the sweet treats handed out by strangers at Halloween. But it seems that most stories of "Halloween sadism" are just that, stories. No child seems to have been killed by adulterated Halloween candy... well... there is one terrible exception. The poisoned Pixy Stix of Pasadena, TX. For a full list of sources used in this episode visit Tim Harford.com See omnystudio.com/listener for privacy information.

Cautionary Conversation: The Conspiracy Theorist Who Changed His Mind
Charlie Veitch was certain that 9/11 was an inside job. The attack on the World Trade Center wasn't the work of Al-Qaeda, but an elaborate conspiracy. He became a darling of so-called "9/11 truthers" - until he actually visited Ground Zero to meet architects, engineers and the relatives of the dead. The trip changed his mind... there was no conspiracy. His fellow "truthers" did not take Charlie's conversion well. David McRaney (host of You Are Not So Smart and author of How Minds Change: The Surprising Science of Belief, Opinion and Persuasion) joins Tim Harford to discuss what happened to Charlie Veitch; what it tells us about those who hold strong beliefs even in the face of damning contrary evidence; and why persuasion isn't always the right answer.

Cautionary Tales Presents: Warfare, The Life of Anne Frank
This week, it's an episode from Warfare, a podcast from our friends at History Hit. It's 1942. The year Anne Frank and her family went into hiding during the Second World War. It was there that Anne began keeping a diary that would become one of the most recognisable testimonies of the Jewish war-time experiences. But what do we know of her life before the war? Host James Rogers explores the Franks' lives before the outbreak of war, and why this story is still so relevant today. You can find more from Warfare at https://podfollow.com/the-world-wars.See omnystudio.com/listener for privacy information.

The Online Date That's Too Good to be True
Single and looking for love, Dr Robert Epstein found himself chatting with a slim, attractive brunette online. She seemed perfect... perhaps even too good to be true. Dr Epstein is an expert on artificial conversation - so surely he'd be the last person to fall for a computer? Chatbots fool us more often than we think... especially when they replicate our very worst conversational habits. To read more on this topic try Brian Christian’s “The Most Human Human”.

A Leap of Faith From the Eiffel Tower
Inventor Franz Reichelt wants to test his novel "parachute suit" from as tall a structure as possible - and the Eiffel Tower seems ideal. Previous trial runs used a mannequin strapped to the chute and have not ended well. Despite this, his plan is to make the Eiffel Tower jump himself. Can he be persuaded to see sense? Self-experimentation - particularly in the field of medicine - has a long and checkered history. Can we learn anything useful from such unorthodox experiments, or are they reckless acts of egotism and hubris? For a full list of sources go to timharford.com.

Cautionary Conversation: Flying on Empty
A meter is longer than a yard. An ounce is heavier than a gram. We harmlessly mix them up sometimes, but a "unit conversion error" when you're filling up the fuel tanks of an airliner can be fatal. Which is exactly what happened to Air Canada Flight 143. Tim Harford talks to mathematician and comedian Matt Parker about how the aircraft came to take off without the proper fuel load, how no one noticed until it was too late, and why such errors give us an insight into just how important maths is to keeping our complex world working as it should. For more "unit conversion errors" check out Matt's book Humble Pi.See omnystudio.com/listener for privacy information.
