I meant when the environments are held equivalent, IQ is unlikely to be much different across races
Objection: Assumes facts not in evidence

The data does not show this. It shows the opposite.

The argument that IQ is largely biological is amazingly strong. Environment, not so much.

The data says "Kids with more books in the house have higher IQ's". And to that, you might say "See, it's environmental"

But then someone else might say "nah, there's more books in the house because the parents are smarter. Biology"
