Cautionary Tales with Tim Harford

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.

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.

More than 100,000 families - many of them amongst the poorest in Britain - put money aside for Christmas gifts and other seasonal treats in a savings club called Farepak. It wasn't a bank, and it wasn't great value for money... and it went bust. Kids went without toys, and festive dinner tables were left bare.

Why would someone put their hard-earned money into such a scheme? And what does it tell us about how we often view Christmas as a time for frenzied spending?

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?

Recorded before an audience at the Bristol Festival of Economics (11/17/2022)

The Dutch went so potty over tulip bulbs in the 1600s that many were ruined when the inflated prices they were paying for the plants collapsed - that's the oft-repeated story later promoted by best-selling Scottish writer Charles Mackay. It's actually a gross exaggeration.

Mackay's writings about economic bubbles bursting entertained and informed his Victorian readers - and continue to influence us today - but how did Mackey fare when faced with a stock market mania right before his eyes? The railway-building boom of the 1840s showed he wasn't so insightful after all.

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?

Polar exploration is dangerous... but trudging hundreds of miles in subzero temperatures isn't made any easier if you're suffering from scurvy. The deadly vitamin deficiency destroys the body and will of even the strongest and most determined adventurer - and it seems that scurvy stuck down the ill-fated expedition of Captain Scott.

But scurvy... in 1912? Hadn't the Royal Navy to which Scott belonged famously cracked the problem of scurvy a century before, with a daily dose of lime juice? How did the 'Limeys' seemingly unlearn that lesson?

Torrey Canyon was one of the biggest and best ships in the world - but its captain and crew still needlessly steered it towards a deadly reef known as The Seven Stones. This course seemed like utter madness, but the thinking that resulted in such a risky manoeuvre is something we are all prone to do when we fixate on a goal and a plan to get us there.

Disturbing the remains of the Egyptian pharaohs is known to incur a deadly curse, so why did a team of archeologists still risk inciting the wrath of King Tutankhamun by entering his burial chamber? And how many of them met a premature end for their impudence?
