I dislike the framing around IQ. It feels like IQ here just refers to how advanced a country's education system is. The real missed opportunity is not creating the right incentives for learning.
Education, Nutrition and basic physical needs met, the linked post equates IQ as if it's a national characteristic of a population which is kinda debunked and closing rapidly on "science" that ends badly.
It also plays with statistics quite a bit (lies, damn lies and government statistics been the old refrain).
All of that is putting aside that IQ itself is deeply flawed both because a) you can't reduce human intelligence down to a single number that way at best it's a weak measure of the type of intelligence been tested for b) IQ tests vary, both in type and scope and are deeply flawed when applied across socio-economic groups in the same society never mind across societies.
There is always variation within a population but I suspect that culture plays a much bigger role.
Case in point - Jewish people are 0.2% of the world population, they've won ~20% of all Nobel prizes awarded.
