The reasons can be debated, but it's a fact that on IQ tests, American blacks score about 1 standard deviation (15 points) below whites. A common threshold for a gifted program is an IQ of 130, 2SD above average. If you demand that all racial groups be proportionally represented, you cannot have a gifted program. You will not get proportional representation among FAANG programmers either. In general, America needs to make a choice between non-discrimination and government-enforced equal outcomes. Charles Murray's book "Facing Reality: Two Truths about Race in America" (2021) discusses this. He co-authored "The Bell Curve" (1994).
