On the average, IQ is 100. That is quite heritable. I’m not sure that’s meaningful genetically.
Even correlated high IQ across generations can easily be a nuture over nature deal—see the above article for one hypothesis.
Finally, even if high IQ is genetically heritable, it may still require cultural or experiential “activation” to nuture intrinsic ability.
There are simply too many variables to casually state any causal relation.
- ldiracdelta 8y agoNo, the average of white people was normed at 100. I'm saying the average case is that people are the average of their parents. I'm not a genetic determinist and I am not an environmental determinist, but there is vast amounts of evidence that IQ is, for a large proportion of the causality, a heritable trait.
