IQ-matched controls would be much better as “educational attainment” is often just a proxy for IQ. You would also need to control for things like age and, relevant to LW, being in grad school.
Well, it depends on what you’re interested in. Educational attainment and IQ are correlated, so if you control for one, any of the two, the effect of the other one lessens.
I would argue that IQ is more important since it causes the educational attainment and not vice versa.

I was under the impression that the effect of IQ on income mostly disappears once educational attainment is included.
