Race/ gender on intelligence

Nature article on race and IQ. (Nature is one of the best biology magazines. It's very difficult to get published in Nature.)

On the other hand, WHO does have different BMI standards for different races.
Normal weight is 20~25 for white people, but 18.5~23.5 for Asians.
That's another minor thing.
Okay well i don't really understand your point bringing up brain size when brain size does not necessarily dictate intelligence. Humans have neither the largest brain size nor the largest brain size in comparison to the rest of their bodies. Not only that, but Albert Einstein had an average sized brain despite being obviously intelligent. One of the issues is that it's hard to accurately measure intelligence (IQ isn't really reliably), but really I don't think there's a lot of support behind the theory that having a brain weigh more means an individual is more intelligent. Also, any organ/body part that both males and females have, the males' body parts will always be statistically larger. Women have smaller brains in general than men, but that's not indicative of any sort of intelligence.
I read some of the second article you linked but it was long as fuck. As you seem to be ignorantly trying to justify China's supposed teachings of white supremacy with this study, I don't really understand your point, mainly because it said that Asian people were "more intelligent" than white people. While I mostly attribute perceived intelligence to society and upbringing (each individual has different capabilities, but I think on average a black person would have the same ability to succeed as white or anyone else), the study itself says Asians are the "smartest". So why would Asian countries teach white supremacy if they're supposedly "more intelligent" (again, I'm only going along with your retarded idea that certain races are naturally more intelligent than others, based on this study that you cited)?
Anyway I could go on and on about how I don't believe that average intelligence is higher by a significant margin among the races, but obviously you will state that statistically whites and Asians are better than the rest of people, or whatever.
But one thing still bothers me about what you've said. "Why do Americans not teach White Supremacy in their classes if whites are statistically more intelligent?" Well, most people in America don't believe that white people are inherently (let alone statistically) more intelligent. But even if white people were more intelligent than blacks, latinos, arabs, or whatever, why would that make white supremacy okay?? The difference in intelligence between the smartest and dumbest individuals is not a gap nearly as large as the gap between a human and an animal, for example. Let's say these bullshit statistics actually prove something about innate abilities. The difference of intelligence between 2 groups of 2 people is not significant enough to deem one as superior or worth better treatment.
At the end of the day, there will be black people smarter than 99% of white people. And white people smarter than 99% of black people. And white people dumber than the vast majority of black people, and vice versa. These people don't deserve to be treated as "inferior" or superior because, theoretically (again, I'm going along with your bullshit hypothetical which i can't stress enough is blatantly false), their race of people is GENERALLY less intelligent by a small margin.
We live in a society where black culture is prominent in music (the most streamed male and female on spotify in 2016 were both black), and black people have brought many innovations to culture and technology. In America, there are multiple individual of every single race who have contributed more to society than you, I, or most people in the world have. White supremacy creates a platform to put down these important people. There are fantastic individuals of every race regardless of "average intelligence".
Also you seem to believe Americans are "taught" racial equality. A lot of Americans are racist. Most Americans just "pick up" this crazy concept of racial equality because we live in a country that actually has multiple races of people lol..
tl;dr white supremacy is bullshit and even if white ppl were statistically more intelligent it wouldn't be acceptable to teach a principle like this. But the idea that white people are statistically born more intelligent is ridiculous too.
Also before anyone complains this post is off-topic the prominence of this belief that white people are superior is a large part of what led to Donald Trump becoming our next president, so I think it's important to address the issue!!
