There is no such thing as "average IQ" for countries. An ultra-common low-IQ take, ironically. What is the average IQ of Malawi? Literally nobody knows. Anybody who claims one is lying to you. In "IQ & The Wealth Of Nations" (the Ur-source for these kinds of claims), they got a number for Malawi by averaging Congo, Zaire, and Tanzania. In turn, the Congo numbers were based in part on general cognitive test scores taken from 40 rural children being treated for parasitic infections, projected out to the whole population, and then modified down to "correct" for the Flynn Effect. Those are the kinds of numbers you're citing when you make these kinds of claims.
