Rationally Speaking #180 - David Roodman on "The Worm Wars"

In this episode of Rationally Speaking, Julia talks with economics and public policy expert David Roodman about the "Worm Wars" in social science -- the debate over whether deworming pills are an effective way to fight poverty. Along the way they discuss how to analyze a study, the differences between economists and epidemiologists, and how to make high stakes decisions when all your evidence is flawed.
