In the 18th century, philosopher Jeremy Bentham suggested the Panopticon as a model of a prison where inmates could be constantly observed by just a single prison guard. Although his original idea was never built, the word has come to indicate any system of social control through constant surveillance. Nowadays, we are close to creating such a system, not for prisons, but for our everyday lives. The data about our whereabouts and doings is collected by our smart devices, and available for search by the authorities. I talk with law professor Andrew Guthrie Ferguson about the new reality, as discussed in his book Your Data Will Be Used Against You: Policing in the Age of Self-Surveillance.

Intelligence is a many splendored thing, especially when it comes to comparisons between species. Chimpanzees are better than humans at some numerical tasks, but less good at understanding what numbers actually mean. One window on the ways that species differ is how they play amongst themselves. I talk with anthropologist and cognitive scientist Erica Cartmill about modes of play and other social behaviors among various species, and what they reveal about the ways we all think.

Welcome to the March 2026 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic. Enjoy!
