My personal view is that trying to find one single measure of cognitive capacity is a fool’s errand. Modern IQ tests are battery tests (ie multiple tests in one), but still end up mapping to a single dimension in a normally distributed manner. That is my major problem. In my opinion IQ tests tell us something but I have not seen compelling evidence that particular thing is in fact intelligence.
So short answer: no; long answer: we shouldn’t be looking for one single measure.
