> Nine US states - including California, Florida, Georgia and Michigan - currently prohibit the use of race as a factor in admissions for public universities Sounds like instead of doing polls on opinions and "gut think" that there are already large real-world examples that can be examined precisely to see what that policy does or doesn't accomplish.
At least in California, I don’t think there has been enough time to really know. It was a recent change iirc.
UC Berkeley chancellor publicly denounced the ban when it was upheld a couple of years ago. Then Cal removed SAT/ACT as an admission requirement. Next admission cycle, she sent out an email to all students and alumni (me) cheering that the school is now more diverse. The percentages of White, Black, Hispanic, etc students in the incoming class all increased. Percentage of Asian students sharply decreased. If you ranked the deltas, it was similar to the ranks of average SAT scores for each group (Asian students have the highest SAT scores, etc). I guess the most diverse class would be achieved using a pure lottery system.
