A reader ponts out that, contra Charles Murray, higher levels of education result in higher pay regardless of IQ. Even average-IQ college grads earn much more, as suggested by these graphs. And in general, we are all aware of studies that purport to show that the college degree brings much hgher lifetime earnings.

But recently it’s come to my attention that some of the data used to support the idea that the college degree results in higher income has been manipulated somewhat to show those good results. Perhaps George Leef or Peter Wood might enlighten us on this further when they have a moment.
