Summary Preview

In this episode, Roman Mars interviews Neil MacGregor, the original host of BBC Radio 4's groundbreaking series 'A History of the World in 100 Objects.' They discuss the philosophy behind telling history through objects rather than traditional narratives, the challenges of choosing 100 objects from the British Museum's collection, and how radio as a medium uniquely allows listeners to imaginatively possess objects they cannot see. The conversation explores themes of democratizing history, giving voice to the voiceless, and the complexities of presenting objects with sacred or contested meanings. The episode concludes with an example episode about the Rosetta Stone, demonstrating how a seemingly dull bureaucratic artifact became key to unlocking Egyptian hieroglyphics.

In 1982, a twelve-year-old paperboy, Johnny Gosch, vanished from a quiet Iowa street and sparked an unlikely campaign: the faces of missing children printed on milk cartons by the billions. Roman Mars...

Summary Preview

This episode examines the history of missing children on milk cartons, beginning with the 1982 disappearance of 12-year-old Iowa paperboy Johnny Gosch. The campaign, which started locally and went national, printed billions of cartons but found only two children alive. The story explores how this campaign shaped American fears around child safety, the racial disparities in which cases received attention, and how stranger danger mythology persists today despite most abuse coming from people children know. Through stories like Bonnie Bullock—who found herself on a milk carton—and modern conspiracies like Pizzagate, the episode reveals how we prefer comforting fantasies about external threats over confronting systemic realities of child abuse.

Summary Preview

Philosophy professor C.T. Nguyen joins Roman Mars to discuss his book 'The Score: How to Stop Playing Someone Else's Game,' exploring how metrics and scoring systems shape our lives. Nguyen introduces the concept of 'value capture'—when simplified, quantified versions of our values take over our richer, more nuanced goals. The conversation examines the paradox of scoring systems: they create beautiful, joyful experiences in games but often drain meaning from work, education, and parenting. Through examples ranging from philosophy journal rankings to fly fishing, Nguyen reveals how we can recognize when we're playing someone else's game and reclaim agency over the metrics that govern our lives.

This episode explores how the Webster Blueback Speller, a pocket-sized literacy tool created by Noah Webster in 1783, became an unexpected instrument of freedom for Black Americans.
