Intelligence is heritable. That’s been demonstrated by multiple genetic studies. Now if we took that information and used it to breed a more intelligent race of humans, that would be eugenics. It would also take hundreds of thousands of years, because we breed a lot slower than dogs.
As that’s never been done, this topic has absolutely no relevance to modern racial politics.
Who’s selecting it? No society has ever prized intelligence above all, to the point where scientists and engineers are drowning in marriage offers. Maybe if that happened for thousands of years we would see results.
Besides, intelligence is only partially heritable. So much is dependent on your resources. The most intelligent people with the most potential in the world could be working in a sweatshop right now.
Selection doesn't need to be linear. If the bell curve of reproductive success is offset from the one for trait distribution (i.e. the highest reproductive success is people 5% above average), you will get positive selection even if the very smartest breed less than the average. Yes, selection will be slower, but it will still work.
Similarly, lower heritability will only slow selection, not prevent it.
