For big countries like US, China, Russia, etc, these IQ numbers are misleading. Southern US has very low test scores. And China and Russia have many different ethnic groups as well. The people in inner Mongolia of China or central Asians in Russia do not have the same IQ as the Han Chinese or European Russians. I don't think PISA tests are given to people of those ethnicities in China or Russia.
All of this academic speak is so hilarious and memeable.

It's better to frame it as 'basic skills' than IQ. It can't be as easily dismissed, and it really gets at why we care about IQ in the first place.
There's basically the US, Europe, Australia, Canada, New Zealand, Japan, China, Korea, South East Asia and everywhere else lol
