''massively shaped by environment'' 
leftists nonsense. IQ is majority determined by genetics.
Which is why there are no super genius aboriginals.
Jesus Christ, can you guys ever stop trying to turn literally everything into some stupid drama about 'leftists'?
While I'm sure 'The Jolly Heretic' is absolutely riveting with his 'based' takes, you are misreading me, and you quite obviously agree with the part regarding the folly of tolerating intolerant cultures. I think that
culture can produce large differences in behavior across populations.
Is Steven Pinker a deranged 'leftist'?
We also know that a lot of our evolution had to have taken place before the human races diverge because we're pretty much birds of a feather. If you took a bunch of human babies from anywhere around the world -- from Australia, New Guinea, Africa, Europe -- and scrambled the babies at birth and brought them up in any society, they'd all be able to learn the same languages, learn how to count, learn how to use computers, learn how to make and use tools. It suggests that the distinctively human parts of our intelligence were in place before our ancestors split off into the different continents.
So in a sense we're all Africans, and if the first group that budded off from the African population and ended up in Australia did so sixty or seventy thousand years ago, then our evolution had to have been pretty much complete by then, because today's Australians and today's Europeans and today's Asians and Africans are all the same species with pretty much indistinguishable cognitive abilities.What about the author of
The Bell Curve? Who stated:
If the reader is now convinced that either the genetic or environmental explanations have won out to the exclusion of the other, we have not done a sufficiently good job of presenting one side or the other. It seems highly likely to us that both genes and environment have something to do with racial differences. What might the mix be? We are resolutely agnostic on that issue; as far as we can determine, the evidence does not yet justify an estimate.Heritability is about differences
within a population in a given environment, not about differences between groups as a species. I said that human beings are a very young, genetically homogeneous species.
Smart parents generally having smart kids is a statement about statistical variation
within groups, and I agree with it. However, contemporary biology does not support the idea of permanent racial hierarchies or a 'master race.'
We know that over the last century, average IQ scores in
every country studied have risen significantly. Genes do not change this fast. Therefore, the most plausible explanation is environmental: education, nutrition, reduced exposure to neurotoxins such as lead, and so on.
Genetic differences between human populations are relatively small, and most variation exists within groups rather than between them. Intelligence is heritable enough to produce stable individual differences, but environmentally malleable enough to transform populations within decades. That is, it is said, exactly what one would expect from the same organism operating under different environmental conditions.
Again, this is a complex field, and I do not claim deep knowledge of it. Experts disagree about research methods and data quality, but those who attempt to twist everything for ideological purposes and reduce it all down to left-wing conspiracies just reveal that they have no intention of engaging seriously with the literature. YouTube cranks and their followers treating IQ as the sole measure of man are simply tedious.
Now, if you don't mind, I'd prefer that we turn our attention back to the
real Getbig Red Scare and uncovering just who is and who isn't a communist in this thread!
