Japan is right up there.
“The level in the United States is lower because of a considerable number of blacks, Mexicans, and Puerto Ricans.”
-Yasuhiro Nakasone
So what’s the big deal?
Yes, the results from 2022 of the same assessment with the United States races separated out. I am sure it's the same this year.

RE: “The level in the United States is lower because of a considerable number of blacks, Mexicans, and Puerto Ricans.”
Nakasone said that in the 1980’s.
That statement is like the film Blazing Saddles when Mel Brooks made it. IT CAN’T BE SAID (MADE) TODAY FOR FEAR OF BEING CALLED THE “R” WORD.
I suspect a lot of European countries with lower scores have the same issue as observed by Nakasone.
