17. Emily Oster: “I Am a Woman Who Is Prominently Discussing Vaginas.”

Author: Freakonomics Radio + Stitcher April 11, 2026 Duration: 41:32
In addition to publishing best-selling books about pregnancy and child-rearing, Emily Oster is a respected economist at Brown University. Over the course of the pandemic, she’s become the primary collector of data about Covid-19 in schools. Steve and Emily discuss how she became an advocate for school reopening, how economists think differently from the average person, and whether pregnant women really need to avoid coffee. This episode originally aired on February 26th, 2021.

Steve Levitt, the Freakonomics co-author known for his unconventional economic lens, turns his curiosity toward the people who fascinate him in People I (Mostly) Admire. This isn't a series of dry interviews with predictable heroes; instead, Levitt seeks out genuinely interesting high achievers from all walks of life, engaging them in conversations that are as surprising as they are revealing. The premise is built on a personal, almost confessional note-he frames it as his own "interesting midlife crisis," a quest to understand the drives and obsessions of exceptional people. Within this podcast, you'll hear the intricate story of a renegade sheriff implementing unorthodox reforms within Chicago's jail system, and travel to the Arctic tundra with a biologist whose work uncovers fundamental secrets of evolution. In another episode, the mechanics of memory are unpacked through a trivia champion who mastered 160,000 flashcards. Produced by Freakonomics Radio and Stitcher, each conversation delves beyond surface-level success to explore the quirks, failures, and unique thought processes that define these individuals. It’s a series for anyone who enjoys deep dives into the minds that shape our society and culture, all through Levitt’s characteristically probing and often humorous dialogue. You come away from an episode not just with knowledge, but with a nuanced sense of the person behind the achievement.
