Concerning [5], the article says he was rejected at UC Santa Barbara. Haven't checked in a while, but I believe UCSB historically accepts 40-50% of first time applicants. The schools were not using SAT scores at the time, and UC has banned race considerations in admissions for nearly 30 years. Surely there's more to this story.

Most schools that say they don't consider race in admissions mean they don't use a racial quota where e.g. they require x% of the student body to be some minority or whatever. That's because such quotas have been ruled illegal. But the way admissions generally work is that your application is graded on a points system, and they get around the law by using a points modifier based on race. And that modifier can be adjusted as necessary to ensure they get exactly x% of the student body to be that minority. So it's racial quotas by proxy.

Another modifier is going to be parental income, which I think makes much more sense than race. But those two modifiers can compound to make it where something like an Asian from a high household income family needs to essentially be the next Einstein in order to be admitted over an average student who happens to be from a historically poor performing minority.

They “banned” them. This lawsuit contends they don’t actually stop using them. That's the basis of the claims. Read it
