You Don't Have to Be Smart to Be Rich

I wonder if Bryan Caplan has seen this?

"Your IQ has really no relationship to your wealth. And being very smart does not protect you from getting into financial difficulty," Zagorsky said.

The one financial indicator in which the study found it paid to be smart was income. Those with higher IQ scores tended to get paid more than others.

While other research has also found the IQ-income link, this is one of the first studies to go beyond income to look at the relationship between intelligence and wealth and financial difficulty, he said.
