At the moment I’m working for Radiolab, helping revisit and rethink some of their original episodes, like these:

Where the Sun Don’t Shine

Today we take a quick look up at a hole in the sky and follow an old story as it travels beyond the reach of the sun. We hear from some moon-peeping listeners and then, on the 40th anniversary of their launch, we check in with the Voyager space probes. We revisit the story of the romantic time capsules that were placed onboard, and a question we asked five years ago: where exactly is Voyager 1?

Driverless Dilemma

Most of us would sacrifice one person to save five. It’s a pretty straightforward bit of moral math. But if we have to actually kill that person ourselves, the math gets fuzzy.

That’s the lesson of the classic Trolley Problem, a moral puzzle that fried our brains in an episode we did about 11 years ago. Luckily, the Trolley Problem has always been little more than a thought experiment, mostly confined to conversations at a certain kind of cocktail party. That is until now. New technologies are forcing that moral quandry out of our philosophy departments and onto our streets. So today we revisit the Trolley Problem and wonder how a two-ton hunk of speeding metal will make moral calculations about life and death that we can’t even figure out ourselves.


Back in 1995, Claude Steele published a study that showed that negative stereotypes could have a detrimental effect on students’ academic performance. But the big surprise was that he could make that effect disappear with just a few simple changes in language. We were completely enamoured with this research when we first heard about it, but in the current roil of replications and self-examination in the field of social psychology, we have to wonder whether we can still cling to the hopes of our earlier selves, or if we might have to grow up just a little bit.

How to be a Hero

What are people thinking when they risk their lives for someone else? Are they making complicated calculations of risk or diving in without a second thought? Is heroism an act of sympathy or empathy?

A few years ago, we spoke with Walter F. Rutkowski about how the Carnegie Hero Fund selects its heroes, an honor the fund bestows upon ordinary people who have done extraordinary acts. When some of these heroes were asked what they were thinking when they leapt into action, they replied: they didn’t think about it, they just went in.

Neuroscientist Robert Sapolsky says there is a certain kind of empathy that leads to action. But feeling the pain of another person deeply is not necessarily what makes a hero.
