"Not in the US. Black people in the US don't get to pick their race unless they can pass."
Yes they can.
Uh, no, they can't. It's called the real world - get to know it.
There's a strong correlation between IQ and mental age.
So? That's measured over time in a given person. It doesn't measure age between people. IQ does not measure mental age. There are plenty of childish people with high IQs around - some of them are even children.
I presented evidence that IQ has a strong heritable component: between 50 and 85%
Thats measured between generations within families. It doesn't hold between populations.
The same is true of all sorts of mental aptitudes including creativity, mathematical ability, motivation, etc... If you follow the scientific evidence to reach a conclusion based on good evidence, then this is the case. Statistics show it to be a strong cogent argument. Probably, within this century, we'll use genetic engineering to ensure all humans have above 120 IQs. Then the point will be mute.
That's "moot". And it won't happen in America - this society won't even provide a hot lunch and a grass playground for black kids.
Meanwhile: You continue to screw up basic population genetics. You have been provided with the example of height - which is at least as strongly heritable, within families, one generation to the next, as IQ. You have the example of Japan, right in front of you, for height - all those short Japanese in the 1950s passed on their 75% or better height inheritance to their children, and their children are not short.
"Heritability" does not apply to sociologically defined populations.
Like I said - a lot people from India are US black. Look at him. US racial categories are biologically bullshit.
I can go you one better - I know at least one woman who changes race seasonally, in Minnesota. What's your point?
It should be noted, Morgan Freedman has stated on numerous times: STOP talking about race. Just stop it, and it'll go away. I agree.
Let's start with the police.
Meanwhile, until the police and the courts and the schools stop reacting to race, it's not going to go away. It is, instead, going to quadruple black men's chances of being jailed for smoking dope, and looking for work with a felony record from then on, and their children's chances of having a father who can't pay for music lessons or a house in good school district, and being lead poisoned on top of breathing heavily polluted air. All of which affects IQ - including cross-generationally. And whichever race they would prefer to be is not going to matter at all - nobody's going to ask them.
The evidence suggests the Flynn Effect was conflating IQ with test-taking experience. The IQ in the West may have been dropping for over 100 years. AAMOF, there's some good reflex data that suggests this is the case.
The "test taking" explanation was disproven. The reflex data don't measure IQ, and their correlation with measured IQ is negative - whatever they are measuring, it's obviously not the the same thing as whatever IQ tests are measuring. And so forth.
