The other day, I read a statistic about my hometown of Washington D.C. that knocked my socks off. In D.C. high schools, 60 percent of students were chronically absent in the last school year. That means they missed one day of school every two weeks. Among ninth graders, it’s even worse: One-third of D.C. freshmen were absent for the equivalent of six weeks of school. The New York Times reported that, nationwide, one quarter of public school students are now chronically absent. That figure has practically doubled since before the pandemic. And it’s doubled across all sorts of districts—rich and poor, liberal and conservative. Today’s guest is Nat Malkus, a former teacher who is the deputy director of education policy at the American Enterprise Institute. We talk about why school absences have exploded across the country; why some people think this just doesn’t matter; why we think it might matter quite a bit; and what teachers, parents, and lawmakers should do about it.

Harvard evolutionary biologist Daniel Lieberman joins the show to talk about his provocative “mismatch theory,” why humans are dysevolved for the modern world, and why exercise is the ultimate miracle drug.

Derek is back, and ... he's a new dad! After several weeks of parental leave, he talks about what's surprised him about new fatherhood. Brad Stulberg, the health and science writer, returns to the show to discuss the psychology of major life transitions, why westerners—and, in particular, Americans—are so bad at dealing with challenges to their identity, and his new book, 'Master of Change.'

Russia’s military isn’t just a little bit bigger than Ukraine's—it has three times more armored vehicles; four times more ground forces; five times more tanks; and 10 times more aircraft. But for now, David is holding up against Goliath. How is this happening? And how long can Ukraine hold out? Russia military analyst Rob Lee and diplomacy expert Max Bergmann explain how Ukraine is shocking Russia—and the world.

Three in four Americans say the U.S. and its allies should ban Russian aircraft over Ukraine by establishing a “no-fly zone.” Dozens of foreign policy experts agree. So do many Ukrainians. Is this the policy that could end the war, or is it an idea that could end human civilization as we know it? (Maybe it's both.) The author and foreign policy critic Robert Wright joins the podcast to debate the pros and cons of a no-fly zone. Host: Derek Thompson Producer: Troy Farkas Learn more about your ad choices.

Imagine running from your home, from a foreign army, knowing that every decision you make could be the difference between life and death—stay or flee? Turn left or right? Leave at 5 a.m. or 6 a.m.? That is the world in which today’s guests live. Five Ukrainians who live in—or have recently fled from—Kyiv tell Derek what it’s like living in the Ukrainian capital, escaping to Poland, and returning to Kyiv to fight the Russian army.
