Episode 71: The autism epidemic

Robert F. Kennedy, Jr. can’t be wrong about literally everything, can he? His latest controversial statement is that he wants to find the “environmental exposure” that has been causing the huge spike in autism rates over the past few decades.

In this episode of The Studies Show, Tom and Stuart look into whether there really is an autism epidemic in the first place—and if there isn’t, why the diagnoses might be going up so quickly anyway.

The Studies Show is brought to you by Works in Progress magazine. This week we discussed the article from the most recent issue about the UK’s land value tax—a cautionary tale of a policy that might sound good on paper, but was utterly cursed in practice. Find this and so many more fascinating articles about human progress at worksinprogress.co.
