Every so often there’s a controversy related to IQ. The latest was caused by [checks notes] the new Vice President of the US attacking the IQ of a political podcaster on Twitter.
You could argue that the VP should have better things to be doing. But Tom and Stuart certainly don’t, because they’ve recorded a whole episode of The Studies Show on the science of IQ. Hasn’t IQ been debunked as a measure? Does anyone take it seriously in 2025? Doesn’t an IQ test only tell you how good you are at doing IQ tests? In this episode, find out the answers to all these questions and more.
The Studies Show is sponsored by Works in Progress magazine. It’s an online magazine associated with the broad “progress studies” movement, where you can find excellent, data-driven essays on what works to drive scientific and technological advances. You can find every issue of the magazine, for free, at worksinprogress.co.
