Standards only matter if they are relevant.
Why do you not think that academic performance is a relevant standard for med school admissions?
I think it is very relevant. It is not the only relevant thing, of course, but is is very relevant. Unlike race and ethnicity.
We are talking about here and now. You keep harping about the past, as if that somehow justifies discrimination today.
Medical schools are keenly invested in admitting only well qualified students who will complete their studies and become physicians.
I am unaware that medical students admit students whose GOAs or MCAT scores or combination fail to meet that threshold.
Data show that black, Hispanic and American Indian applicants are admitted with significantly lower scores and grades than white and Asian ones. That should not be allowed. Same standards should apply to everybody.
If you look at the data, blacks have a 505.7 and standard deviation of 6.6 [yes, SD is appropriate here since we are just looking at population distributions and not doing hypothesis testing]. That means that ~16% of all black matriculants have the MCAT score of 499 or less. Asian students the mean is 514.3 and the SD is 6.0. That means that only ~2.5% have an MCAT of 502 or less. That is a huge difference in academic preparedness.
I am unaware that there are any imperial studies which have established that those medical students admitted with the highest scores and best GPAs end up making the best physicians.
Imperial studies? I am unaware of any studies that show that certain skin color or ancestors who spoke Spanish make the best physicians either.
But to get back to "imperial studies",
MCAT scores do predict medical school performance.
