If a proposed test didn't agree with the existing ones, it wouldn't be used as an IQ test.
If it correlated better with the vast battery of non-IQ-tests which nevertheless exhibit a positive manifold, it'd be used.
Thinking about the geometry of that, it seems to me that any two things that correlate positively with all of a "vast battery of non-IQ-tests" are likely to correlate positively with each other, and the more diverse (i.e. less correlated with each other) that battery is, the tighter the constraint it places on the set of things that correlate with all of them.
Furthermore, if it correlates better with that battery than existing IQ tests do, it again seems, just from visualising the geometry, that it will correlate worse with the IQ tests than they do with each other.
But my intuition may be faulty. Do you have a concrete example of the phenomenon?
Indeed. To the extent that existing IQ tests are not terrible & crappy (and, y'know, they aren't), any better IQ test is still going to correlate heavily with the old ones.
