New data shows that less than half of American newborn boys are circumcised, a major decrease from around 90% in the 1960s. But how and why did circumcision become so common here in the United States? This week, we speak to an epidemiologist, a sociologist, and an anti-circumcision “intactivist” to explore the origins of the procedure, its health impacts, and why attitudes around it are changing.

Our guests this week are Johns Hopkins epidemiologist Dr. Kate Grabowski, Vanderbilt University associate professor of sociology Laura Carpenter, and Intact America founding executive Georganne Chapin.

Due to time restraints, not everything can make it into the final episode. We tried our best to represent all sides of the issue fairly, respectfully, and with proper attention to detail.

On today’s episode, we’re tackling a question from a listener named Joel: Why do singers lose their accents when they sing?

Our guest this week is New Yorker writer Kelefa Sanneh. In this wide-ranging conversation, we explore identity in country music, why Taylor Swift stopped singing with a twang, how Drake changed the way people think about authenticity in hip-hop, and why Adele and Harry Styles don’t sound British when they sing.

This week’s topic came from a listener who asked if micromanaging is a more productive work-style than a more “free range” approach. We talk about our own work experiences, and answer a few other miscellaneous work questions about performance improvement plans (“PIPs”), handling an incompetent boss, office odors, and more.

Our guest this week is Erik Baker, historian at Harvard, editor at The Drift, and author of Make Your Own Job: How the Entrepreneurial Work Ethic Exhausted America, who walks us through the history of the corporate work structure and evolution of management styles.
