https://en.wikipedia.org/wiki/Heritability_of_IQ This is one of those things that we can't really talk about anymore. There are racist connotations, ironically to both sides of the argument. To say it has a strong genetic component could be construed to mean certain races have IQ differences. To say it does not have a genetic component can be construed to saying current members of races are largely responsible for their own IQ, which is denying the effects of unequal treatment of races. As for science, there's a problem with heritability. Do you mean genes? Or do you mean "average" attitudes to the intelligence and education of children, which can correlate with race and location? Or do you mean environment in other ways (such as money and available resources, divorce status of parents, ... which again correlates with race)? Genes alone (from split up twin studies), explain about half the variability in IQ (which translates to about 4 IQ points). The environment you had as a child explains the rest. |
