Third world countries are poor and devastated and can't afford schools, infrastructure for their children that's why they are low IQ. Also their climate and environment suck which influences their intelligence and way of thinking.

>low IQ poopskin doesn't realize the entire point of IQ is to test intelligence independently of education
Keep coping.

blacks literally have an underdeveloped prefrontal cortex and less ccs of brain, fucking retard.
America has fed and housed and schooled niggers for centuries, and they're not getting any smarter.
>but muh Thomas Sowell, muh DeGrasse Tyson
regression to the means dictates that even a smart nigger will sire an average (dumb) nigger.
African infants literally don't pass the mirror test, fucking Magpies do.

IQ is 80% genetic. The rest is mostly nutrition.
Education is basically irrelevant.

>>511140506 (OP) IQ is genetic. If you take two kids, one with a high IQ and another with a low IQ, and you give them the same education, send them to the same school, they have the same teacher and the same curriculum, the high IQ kid will excel and the low IQ kid will fail. That's how IQ works. People with high IQs are able to grasp complex subjects with ease, and people with low IQs are not able to do so.
