IQ is more about the trade-off between stress and reward

There's an interesting post here on crookedtimber about the heritability of IQ.

What I think is never said about IQ is how it is the result of a series of small decisions that you make during the test, and therefore at least as much about emotion and personality as about intellectual capacity. When you do an IQ test some questions will come easily, but the harder ones are slightly stressful. You have to decide how much stress you want to endure in order to get one more point on your total.
