Wrong. In fact, they did make such a test, but the experiment went disastrously awry.

Two African-American professors claimed that standardized tests were biased in favor of white kids, and so to prove their point designed a test that was purposely supposed to be biased in favor of African-American students. The intent was to give the test to mixed classes, and then when the Black students scored higher on average, this was to be used as conclusive evidence that tests can be made biased.

By now you’ve probably guessed what happened. They gave their purposely pro-Black test to mixed classes — and the white students still outscored the Black students.

Ooops!

It was such an embarrassment, they tried to cover it up. But it was too late — they had pre-emptively publicized the experiment too much already.

Hmm, Ok you got me to do a little digging. I found this link. Its Wikipedia so take it with a grain of salt…
