Be careful with conflating the different meanings of "IQ". There is (1) IQ test taken after adolescence, which plenty of folks consider newage nonsense (it has useful correlations with some mental tasks, but it is not clear whether it deserves a name as fundamental as "IQ") and there is (2) various tests given at young pre-adolescent ages which is quite a bit more interesting when trying to distinguish nature from nurture. The gap you are referring to, is it about (1) or about (2)? The OpenAI model might be talking about 2.
