Curious: Given the well-understood knowledge that there are many complex matrixes of “intelligence” and the well-documented cultural biases of IQ tests, what is the purpose of your consider work on this particular data set? Please clarify.
So, why build global maps of intelligence tests across a great variety of cultures? I would think that any comparison of country data, in this case, would have to group countries by cultural similarity to get valid country comparisons. I’d ask you to clarify what the point of all this painstaking mapping of data is.
Another remark; the TIMSS SDs do not seem to be the same size as the PISA ones. Thus Japan is far below 108 and Pakistan and the Philippines are far above 65.
yet Kenya scores HIGHER than Morroco so that can't be it. This seems like a huge point against that theory. I wish Seb would respond but that hasn't happened

I don’t think I’ve ever denied that IQ tests are culturally biased.

The importance of cultural bias is a matter of degree.
Why no Bangladesh here?

IMO the TIMSS Science is worse than useless. The TIMSS Math tests actually test good questions.
why is the morroco IQ lower than other North Africans, that doesn't make much sense and I would love your input

If you want more data in the PIAAC data explorer step 2 you can select age groups in 5-year or 10-year bands:

Ah, so my country gets the good-boy badge.
Ukraine?
Updated. Looks flat at ~94 or so.
Ukraine's and Russia's scores must have dipped astronomically after 2014 and 2022.
