Host Megan McArdle talks with physician and Washington Post contributing columnist Leana S.

And she argues that if America wants a more stable political future, it will need to return to a more normal kind of politics.

Prediction markets are having a moment. But what are they actually good for? Economist Robin Hanson has been thinking about this for decades. Long before betting markets went mainstream, he argued they could do more than forecast the future — they could help us make better decisions.
