My prediction is the correlation is about 0.30-0.40.
As others have pointed out, there are a lot of unmeasured variables not being controlled for in this finding as well.
I'm not surprised board exam scores predict outcomes, I just think there's lots of other variables along that path from one to the other, and even more from MCAT -> board exam.
I'm just suggesting that the observed prioritization of DEI objectives at the expense of the admission process not being completely merit-based likely results in some additional deaths. I agree that there are multiple factors involved that will predict physical competency, not just those that the DEI policies adversely affect.
