Today In History with The Retrospectors

Cass Sunstein and Richard Thaler’s bestseller ‘Nudge’ was released on 8th April, 2008, catapulting a new method of behavioural economics into the public psyche - and the hands of policymakers, including David Cameron and Barack Obama.

The book challenged the notion of humans as rational decision-makers, and explained how companies, governments and individuals can ‘nudge’ people towards healthier habits, responsible financial decisions, or civic engagement if ‘decisions’ are framed in the right context - a technique they called "libertarian paternalism."

In this episode, Arion, Rebecca and Olly ask just how effective nudge theory really is; explain how the project was inspired by a bowl of cashew nuts; and discover how Thomas Crapper was centuries ahead of his time…

Former First Lady Betty Ford quietly marked what she would later call her “sobriety birthday” on 7 April 1978: a deeply personal victory following years of dependence on prescription medication and alcohol. 

Though the milestone itself was private, it came just days after a profoundly difficult family intervention at her home in Rancho Mirage, where her husband, former President Gerald Ford, and their children confronted her with the toll her addiction had taken. Initially shocked and defensive, she ultimately recognised the truth in what they said, and within a week resolved to give up the substances that had come to dominate her life.

Ford’s addiction had developed in ways that were, at the time, neither unusual nor widely questioned among affluent Americans: prescribed painkillers for a pinched nerve and managing chronic conditions such as osteoarthritis, alongside regular social drinking. Yet the cumulative effect - slurred speech, diminished public performance, and emotional distance - became impossible for her family to ignore. 

What distinguished Betty Ford, however, was the candour with which she addressed her struggles. After entering a naval rehabilitation facility in California, she publicly disclosed not only her dependence on medication but also her alcoholism; an extraordinary admission at a time when addiction carried intense stigma, particularly among public figures. This openness echoed her earlier willingness to speak frankly on controversial issues, including women’s rights, abortion, and her own breast cancer diagnosis, helping to redefine expectations of what a First Lady could say and do.

In this episode, Arion, Rebecca and Olly unpick the profound cultural impact of her decision to go public; explain how she channeled that momentum into the foundation of the Betty Ford Center in California; and discover how her surprisingly rebellious, modern image marks her out amongst Republican figures of the 70s…

3M scientist Spencer Silver created the adhesive that makes Post-It Notes sticky back in 1968 - but it wasn’t until 6th April, 1980 that the stationery product we all know and love was first released to consumers, in a promotional effort the company termed ‘The Boiasie Blitz’.

The problem? His "invention" wasn’t what his company wanted. Rather than strong, industrial-grade glue, Silver had accidentally made the opposite—an adhesive that was weirdly weak but could be stuck and removed multiple times. A "solution without a problem," as he put it.

Fast forward to 1974, and fellow 3M scientist Art Fry had a eureka moment while struggling with loose bookmarks in his church hymnal…

In this episode, Arion, Rebecca and Olly reveal how a mass giveaway was the key to unlocking the viral marketing power of this ‘self-advertising’ product; discover why the notes’ now-iconic yellow colour came about; and discover an out-of-court settlement that arguably casts some doubt on the product’s remarkable origin story…

Gottlieb Daimler's patent for his high-speed petrol engine (dubbed the "Grandfather Clock") on 3rd April, 1885, wasn't just a technological breakthrough—it inadvertently birthed the motorbike. 

Teaming up with Wilhelm Maybach, the duo had crafted a compact engine featuring float-metered carburetors and mushroom intake valves, all powered by hot tube ignition. This engine found its way into their first vehicle prototype, the Petroleum Riding Car, which bore little resemblance to today's motorcycles but represented a pioneering step towards motorised transportation.

In this episode, Arion, Rebecca and Olly explain how it was not Daimler, but his son, Paul, who became the first-ever motorbiker; consider the steam-powered predecessors that could potentially lay claim to inventing the motorbike; and explain how Daimler took what he’d learned from these experiences to establish Mercedes…

With a single, deliberate shot, Roger Sharpe played pinball for the council of the New York City Council chamber on 2 April 1976, theatrically overturning a 34-year ban on the game by proving it could be a game of skill. 

The city’s censorship of the game had its roots in the economic strain of the Great Depression and the moral recalibrations following Prohibition, when pinball machines, often found in arcades and bars, became associated with petty gambling and organised crime. New York’s mayor, Fiorello LaGuardia, made them a particular focus of his anti-corruption campaigns, arguing that they exploited the young and the poor. His administration confiscated and publicly destroyed machines, even melting them down during the Second World War as part of the wartime metal drive. 

In this episode, Arion, Rebecca and Olly track the shifting cultural attitudes of the 1970s, thanks in part to the Who’s ‘Tommy’; explain how the introduction of flippers in 1947 (notably in the game Humpty Dumpty) fundamentally pivoted pinball into a game of skill; and reveal the world record for the longest ever pinball marathon…
