Insight Instead of IQ

Intelligence is obviously very real. However, you don't care about intelligence in most cases. You either care about reaction times or insight.

For the most part, IQ is necessary but far from sufficient for insight. I'm sure that you can supply just as many examples of high-IQ gulls as I can, if not more. I interpret the fact that you get low-IQ insight ("salt of the earth") not as showing IQ isn't necessary, but as showing that insight isn't actually that difficult in many cases. Rather, the parallel enabling factors are rare. If anything, even rarer as IQ goes up. Lots of mid and high IQs are blocked due to not genuinely desiring insight, rendering their big brains about as socially useful as tits on a fish.
