Season 5, Episode 5
In this week’s episode of Freakonomics Radio, we first explore whether some of the scientific ideas we cling to should be killed off; and then Stephen Dubner and Steven Levitt answer some listener questions.
The gist: Every year, Edge.org asks its salon of big thinkers to answer one big question. In 2014, the question bordered on heresy: what scientific idea is ready for retirement? Experts weigh in. And then Dubner and Levitt talk about fixing the post office, putting cameras in the classroom, and wearing hats.
