Society should not, and I don't think anybody really advocates that today or in the past.

The way I look at it you got two different approaches in using IQ scores on races or subpopulations. Either you can use the low score to rationalize your bigotry and go: "Look at these people! They are stupid, we must have fewer of them!"

The alternative approach is to look the score and say: "Look at these people, they are being heavily disadvantaged! We must find a way to help them, improve their opportunities and raise their IQ score."

Thus you can use IQ scores to rationalize your racism or to expose racism.

That is of course a simplification. But whether you are solidly on the side of a nature vs nurture view of humans will decide a lot of this. Of course biology matters a lot, but the whole point of this article was to show have we have been wrong about IQs of whole groups of people in the past, and there is no reason to assume we are any better today.

I think the safe position is to assume that as groups we all have the same potential given. Reaching that potential relies on giving each individual a rich and positive environment.
