Of course China leads. China is the second largest country by population with three to four times as many people as third place USA, so of course they have many more high performing scientists compared to the USA, and that’s despite the massive amount of brain drain that occurs from China to the USA.

If you sort other countries according to population size, first place India doesn’t have any time left in the day after they get their mouths from around Pissrael’s dick to do any science, and fourth place Indonesia, fifth place Pakistan and sixth place Nigeria all bear the weight of brutal colonial histories for them to achieve their true human potential in the area of science.

If you exclusively measure the student population, Chinese students routinely score the highest in the world across most subjects, but especially science and math.
