Among O.E.C.D. nations, the U.S. has one of the highest rates of child poverty. How can that be? To find out, Stephen Dubner speaks with a Republican senator, a Democratic mayor, and a large cast of econo-nerds. Along the way, we hear some surprisingly good news: Washington is finally ready to attack the problem head-on.

When Richard Thaler published Nudge in 2008 (with co-author Cass Sunstein), the world was just starting to believe in his brand of behavioral economics. How did nudge theory hold up in the face of a global financial meltdown, a pandemic, and other existential crises? With the publication of a new, radically updated edition, Thaler tries to persuade Stephen Dubner that nudging is more relevant today than ever.

That’s what some health officials are saying, but the data aren’t so clear. We look into what’s known (and not known) about the prevalence and effects of loneliness — including the possible upsides. 

In a conversation fresh from the Freakonomics Radio Network’s podcast laboratory, Michèle Flournoy (one of the highest-ranking women in Defense Department history) speaks with Cecil Haney (one of the U.S. Navy’s first Black four-star admirals) about nuclear deterrence, smart leadership, and how to do inclusion right.

Humans have a built-in “negativity bias,” which means we give bad news much more power than good. Would the Covid-19 crisis be an opportune time to reverse this tendency?

Air pollution is estimated to cause 7 million deaths a year and cost the global economy nearly $3 trillion. But is the true cost even higher? Stephen Dubner explores the links between pollution and cognitive function, and enlists two fellow Freakonomics Radio Network hosts in a homegrown experiment.

While other countries seem to build spectacular bridges, dams, and even entire cities with ease, the U.S. is stuck in pothole-fixing mode. We speak with an array of transportation nerds — including the secretary of transportation and his immediate predecessor — to see if a massive federal infrastructure package can put America back in the driver’s seat.

The environmentalists say we’re doomed if we don’t drastically reduce consumption. The technologists say that human ingenuity can solve just about any problem. A debate that’s been around for decades has become a shouting match. Is anyone right?

According to a decades-long research project, the U.S. is not only the most individualistic country on earth; we’re also high on indulgence, short-term thinking, and masculinity (but low on “uncertainty avoidance,” if that makes you feel better). We look at how these traits affect our daily lives and why we couldn’t change them even if we wanted to.

We often look to other countries for smart policies on education, healthcare, infrastructure, etc. But can a smart policy be simply transplanted into a country as culturally unusual (and as supremely WEIRD) as America?

The benefits of sleep are by now well established, and yet many people don’t get enough. A new study suggests we should channel our inner toddler and get 30 minutes of shut-eye in the afternoon. But are we ready for a napping revolution?

Nearly two percent of America is grassy green. Sure, lawns are beautiful and useful and they smell great. But are the costs — financial, environmental and otherwise — worth the benefits?

Bren Smith, who grew up fishing and fighting, is now part of a movement that seeks to feed the planet while putting less environmental stress on it. He makes his argument in a book called Eat Like a Fish; his secret ingredient: kelp. But don’t worry, you won’t have to eat it (not much, at least). An installment of The Freakonomics Radio Book Club.

Cecilia Rouse, the chair of the White House Council of Economic Advisors, is as cold-blooded as any economist. But she admits that her profession would do well to focus on policy that actually helps people. Rouse explains why President Biden wants to spend trillions of dollars to reshape the economy, and why — as the first Black chair of the C.E.A. — she has a good idea of what needs fixing. 

Bapu Jena was already a double threat: a doctor who’s also an economist. Now he’s a podcast host too. In this sneak preview of the Freakonomics Radio Network’s newest show,  Bapu discovers that marathons can be deadly — but not for the reasons you may think.

The pandemic may be winding down, but that doesn’t mean we’ll return to full-time commuting and packed office buildings. The greatest accidental experiment in the history of labor has lessons to teach us about productivity, flexibility, and even reversing the brain drain. But don’t buy another dozen pairs of sweatpants just yet.

The social psychologist Robert Cialdini is a pioneer in the science of persuasion. His 1984 book Influence is a classic, and he has just published an expanded and revised edition. In this episode of the Freakonomics Radio Book Club, he gives a master class in the seven psychological levers that bewitch our rational minds and lead us to buy, behave, or believe without a second thought. 

The human foot is an evolutionary masterpiece, far more functional than we give it credit for. So why do we encase it in “a coffin” (as one foot scholar calls it) that stymies so much of its ability — and may create more problems than it solves?

The man who wants America to “think harder” has parlayed his quixotic presidential campaign into front-runner status in New York’s mayoral election. And he has some big plans.

It’s true that robots (and other smart technologies) will kill many jobs. It may also be true that newer collaborative robots (“cobots”) will totally reinvigorate how work gets done. That, at least, is what the economists are telling us. Should we believe them?
