The Effect of Education on IQ

Bryan Caplan’s claim in *The Case Against Education* is striking: education doesn’t teach people much, we use little of what we learn, and college is mostly about trying to seem smarter than other people - so the government should slash education funding.

It’s a dismaying - almost profane - idea, and one people are inclined to dismiss out of hand. But having read the book, I have to admit that Bryan can point to a surprising amount of evidence in his favour.

After all, imagine this dilemma: you can have either a Princeton education without a diploma, or a Princeton diploma without an education. Which is the bigger benefit of college - learning or convincing people you’re smart? It’s not so easy to say.

For this interview, I searched for the best counterarguments I could find and challenged Bryan on what seem like his weakest or most controversial claims.

Wouldn’t defunding education be especially bad for capable but low income students? If you reduced funding for education, wouldn’t that just lower prices, and not actually change the number of years people study? Is it really true that students who drop out in their final year of college earn about the same as people who never go to college at all?

What about studies that show that extra years of education boost IQ scores? And surely the early years of primary school, when you learn reading and arithmetic, *are* useful even if college isn’t.

I then get his advice on who should study, what they should study, and where they should study, if he’s right that college is mostly about separating yourself from the pack.

We then venture into some of Bryan’s other unorthodox views - like that immigration restrictions are a human rights violation, or that we should worry about the risk of global totalitarianism.

Bryan is a Professor of Economics at George Mason University, and a blogger at *EconLog*. He is also the author of *Selfish Reasons to Have More Kids: Why Being a Great Parent is Less Work and More Fun Than You Think*, and *The Myth of the Rational Voter: Why Democracies Choose Bad Policies*.
