01:00:11 Share

This episode features Rick Nevin, an economist who is known for his research suggesting that lead is one of the main causes of crime. Rick and Julia discuss: how do we know the correlation between lead and crime is a sign of a causal relationship? Has the lead-crime theory made any successful predictions? And is it possible that getting rid of lead could reduce the crime rate down to zero?
