The U.S. is an outlier when it comes to policing, as evidenced by more than 1,000 fatal shootings by police each year. But we’re an outlier in other ways too: a heavily-armed populace, a fragile mental-health system, and the fact that we spend so much time in our cars. Add in a history of racism and it’s no surprise that barely half of all Americans have a lot of confidence in the police. So what if we start to think about policing as … philanthropy?

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.
