A really interesting podcast in which experts in various fields discuss ideas that seem to persist that really should go away. Sometimes these are ideas that exist among experts (the use of mice in clinical trials of cancer drugs) and sometimes these are ideas that exist among common people (the idea that people are either left or right brained)
“In our latest episode of Freakonomics Radio, we run that progression in reverse. Rather than asking if a new idea is a good one, we ask whether it’d be better if some of the ideas we cling to were killed off.”
