How an idea born in a Swedish bank wormed its way into all of our brains. In August of 1973, Jan-Erik Olsson walked into the lobby of a bank in central Stockholm. He fired his submachine gun at the ceiling and yelled “The party starts now!” Then he started taking hostages. For the next six days, Swedish police and international media would tie themselves in knots trying to understand what seemed to them a sordid attachment between captor and captives. And this fixation, later pathologized as “Stockholm Syndrome,” would soon spread across the globe, becoming an easy, often flippant explanation for why people—especially women—in crisis behave in ways outsiders can’t understand. But what if we got the origin story wrong? Today on Radiolab, we reexamine that week in 1973 and the earworm heard ‘round the world. Is “Stockholm Syndrome” just pop psychology built on a pile of lies? Or does it hold some kernel of truth that could help all of us better understand inexplicable trauma?
