Mind Games

We are about to tape new episodes of Tell Me Something I Don’t Know. You’ll be able to hear them later this year in the Freakonomics Radio podcast feed. Details in this short announcement.

Why New York has skinny skyscrapers, how to weaponize water, and what astronauts talk about in space. John McWhorter is co-host; Bari Weiss is live fact-checker.

In this special call-in episode: why some Peruvians eat cats; why operas need repetiteurs; and why we should get rid of prisons. Michael Smerconish (CNN) is co-host; AJ Jacobs (It’s All Relative) checks the facts.

This week, we work on our survival skills: in the desert, on the tundra, and growing food in abandoned warehouses. Actress Sas Goldberg is co-host; A.J. Jacobs (author of It’s All Relative) is live fact-checker.

How to make people like you, why you should lick rocks, and what an awkward person is really thinking. Angela Duckworth (Grit author) is co-host; Mike Maughan (Qualtrics) is live fact-checker.

Things we learn this week: dogs aren't so great at sniffing, men aren't so lazy, and New York doesn't smell so bad (anymore). Gail Simmons (Top Chef) is co-host; Jon Batiste plays his melodica for us; the live fact-checker is Mike Maughan.

Musical crickets, crop-saving wasps — and why you should pre-bug your software. John McWhorter is co-host; the live fact-checker is Bari Weiss.
