How can groups make good decisions? | Mariano Sigman and Dan Ariely

We all know that when we make decisions in groups, they don't always go right -- and sometimes they go very wrong. How can groups make good decisions? With his colleague Dan Ariely, neuroscientist Mariano Sigman has been inquiring into how we interact to reach decisions by performing experiments with live crowds around the world. In this fun, fact-filled explainer, he shares some intriguing results -- as well as some implications for how it might impact our political system. In a time when people seem to be more polarized than ever, Sigman says, better understanding how groups interact and reach conclusions might spark interesting new ways to construct a healthier democracy.

How jails extort the poor | Salil Dudani

Why do we jail people for being poor? Today, half a million Americans are in jail only because they can't afford to post bail, and still more are locked up because they can't pay their debt to the court, sometimes for things as minor as unpaid parking tickets. Salil Dudani shares stories from individuals who have experienced debtors' prison in Ferguson, Missouri, challenging us to think differently about how we punish the poor and marginalized.
