So it is a biological quality.It has social consequences.Tell me the IQ of a 15 year old and I can predict his success in standardized tests he will take 3 years later.
what IQ tests are measuring is not biological quality, it is persons achievement in tests compared to his peers in area test is standardized for, that's partially caused also hopefully by biological intelligence we still don't know where at all is, and what it is, also what is it depending on (genes, which ones?, nurture, early development).
they are hoping that is in the background, causing all those differences.
but it's never just that hypothetical biological in the background, environmental factors are not questionable in psychometric intelligence or IQ.
Yes, of course you can predict it. Everybody can, it's since childhood quite unchangeable.
What was your point here?
If you want to enter the US army you have to have an IQ lower than 110 and higher than 90.All these black and white populations in the army belong in the same range regarding the IQ.I am surprised how you don't know that.This is a biased argument.
If we use your argument, that there is something wrong with black genes we can also assume that IQ of black soldiers was improved through education, so basically black people who are in US army are scoring 100, but thanks to good environment, while white people with better genome were lazy at school and because of that were equal with black ones.
So, next generation of german-american black and white kids had to show some inherent differences, stemming directly from genes ;)
Irrelevant.You don't know the IQ of the parents.You don't know if black or white IQ genes are dominant and will express themselves more in combination.
It looks like a quite simplistic idea about the way intelligence is passing from generation to generation, it's surely not like color of eyes, probably polygenic not only one is responsible.
Why would white or black be dominant? What is the connection between color of their skin and genes for biological I, so you think that those two things are related at all?
is there a proof for that statement, i don't know for it?
Again you don't know which genes are dominant.If black genes are dominant then no matter how many white mix one has,his IQ will be low(black).You have to know the pattern.
Again why would genes for black or white skin have to be related to genes for intelligence.
What genes, what is their connection with genes for assumed Biological Intelligence.
IQ is not just biological quality. We all here know that very well.
