Would not the intelligence of a group effect a groups ability to nurture?
I was agreeing with you. I was just trying to point out that nature interacts with nurture. One of the paradoxes of intelligence theory is that a mixed race child tests higher (as a child) if its mother is white. Another interesting correlation is that children who hear more words, except for declarative sentences like "do this""don't do that", tend to score higher. Yes nurture is important but I have never said it wasn't. But I wonder if culture may be more difficult to change than genetics?
That could be explained by cultural practices, quite easily, I might add.
If the mother is white, the mother probably had a better education and is more apt to pass down the education to encourage her child.
And it is true that children with better access to vocabulary do better...something a black guy discovered...oh, the horror!
