It will probably continue informally if it is struck down. The reason why URMs exist isn't just because of their race. They also tend to have experiences in underserved communities that med schools seek. People seem to think that checking the URM box automatically sends you an interview invite, but that is just not the case.
The problem with SDN is people won't admit that numbers don't mean everything. Why is no one defending all the 4.0/40 applicants who have trouble with interviews? Why don't we yell and scream about how they are being discriminated against? Isn't it about selecting the most qualified people? Or could it be because numbers are only a part of the application?
Being a physician has a lot to do with communication, and the race and experiences of the physician matter.
We aren't here to correct society's wrongs by the admissions process. URMs aren't selected because adcoms feel bad about past discrimination. They are trying to select a population of physicians that can best treat the diverse population.
I've been arguing this point long enough, that I don't really feel like having this debate again. So, I'm dropping out of this debate after this one post. If what I am saying does not makes sense to you, please step out of the premed bubble and do some work in underserved areas and try and appreciate the experiences of a diverse patient population.
