That is indeed what I meant.

It's a whole lot more "obvious" here in South Africa. There are actual quotas, rather than "score" enhancements and juggling like there is in America.

With the assumption that the "range" of ability is equal in both groups. The simple fact that you take a smaller quantity of one, rather than the other, implies that you're taking a different ability range of one group over the other.

So if you have 100 black, 100 white students, and both their group scores range using a normal distribution from 500-1000. But you enforce that only 10 whites can be taken, and 40 blacks should be taken. Then you're guaranteeing that only the "top" 10 of the white students get picked, while with the blacks the top 40 get picked. This means you're going down the distribution and selecting black individuals that have lower scores.

American schools also use quota-like systems.
