The SAT could discriminate against those who are not politically correct also.
I took the SAT in 1960. Several questions on the test were based on a narrow acceptance of a certain theory of evolution (now not pushed in 2019). I knew what answers the test makers wanted. But I left those answers blank.
I see that climate change questions would now have political answers, not scientific answers.
I see history books that are flat out wrong about the 1960s and 1970s.
I wonder, how much is the SAT now based on political correctness?
When I took the tests back in the early 60s, the Verbal section was not my strength and I thought I did most poorly on the reading sections. So I always looked for the sections that discussed something I was interested it. Astronomy was the most usual. I could just answer the questions without doing the reading.
Fast forward to the 90s when my kids were taking the tests. Now I was acing the Verbal sections too when I took the practice tests. And I found again that you could answer about 75% of the reading questions without doing the reading. One had only to pick the most* politically correct statement from the five (Or was it four?) choices given as possible answers. NO POLITICALLY CORRECT STATEMENT COULD EVER BE CONSIDERED WRONG.

* It wouldn't surprise me that if there were more than one suggested answer than might be considered politically correct, that each would be considered as correct.
