This is the story of an experiment. It’s from a show I love called Revisionist History, by bestselling author Malcolm Gladwell. This season he’s devoting every episode to experiments. There’s the experiment that brought iodized salt to our tables. Another episode looks at a kind of failed social experiment that could have reduced opioid overdoses. Anyway, it’s all fascinating — and the episode we want to share with you is no different.

Malcolm has discovered a forgotten box of interviews in the archives of the Library of Congress. They tell the story of 36 men who, in 1945, spent a year in a dingy room under the school football stadium. They were part of an experiment none of them would ever forget. And people are still arguing about what happened decades later.

This is part of a three-part series, and you can hear the rest, and more, by searching for Revisionist History wherever you get your podcasts.
