It's simply a claim about heritability of intelligence. In other words, "Intelligence isn't inheritable like height" according to the author. There are certainly plenty of people who claim that genetics explains a large part of intelligence.
- rowanG077 2y agoIt's very hard to look at heritability and make a genetics conclusion. That's because two people's genes fuse to make a new person. And this process could be chaotic for some traits. So even if trait x is genetic it may not be possible to predict that trait in the children based on the trait in the parents. So it's possible intelligence is genetic even if heritability suggests it isn't. What would be interesting is to look at monozygotic twins. If their IQ scores are more highly correlated then siblings or non-monozygotic twins it's a clear indication intelligence is genetic. But I imagine that the sample set is tiny.
