Throughout history, there have always been a small group of people who prepare for doomsday.  Today, according to a YouGov poll conducted in 2020, roughly one in five Americans feel that an apocalypse is coming. So what’s the obsession with the end of times, and do America’s historical roots inspire survivalism? KCRW’s Jonathan Bastian learns about the lives and mindsets of  people who think the apocalypse is around the corner. Journalist Mark O’Connell crosses the globe in search of preppers and shares his experiences. We also explore the psychology and religious beliefs of preppers, and examine whether the Book of Revelations offers an alternative way to understand apocalyptic moments with Williams College Professor Jaqueline Hiligo and Yale University Professor Yii- Jan Lin.
