Bar passage rates correlate pretty tightly with LSAT scores

From WHY IS THE CALIFORNIA BAR SO RACIST? Racial Disparities Persist In California Bar Exam Pass Rates: White: 72%, Asian: 66%, Hispanic: 61%, Black: 31% from Glenn Reynolds.  

Actually, we looked into this kind of thing among our own graduates some years back, and it turns out that bar passage rates correlate pretty tightly with LSAT scores. This isn’t surprising: One’s a big stressful law-related exam, and the others a bigger, more stressful law-related exam. So if you admit a cohort with lower LSAT scores, that cohort will tend to have a lower bar passage rate. And it’s not linear — there’s a cutoff below which the passage rate plummets sharply. This is, in fact, well-known in legal academia. Many think it’s immoral to admit students at or below that cutoff because their chance of passing the bar is so low. But many schools do so anyway.

Interesting that there is a non-linear disjoint in the scores and failure.  I am not sure I have read that before regarding affirmative action even though it is a common enough phenomena in other processes.  

Affirmative action admissions and student loans are, in reality, deeply unethical, making promises that can't be delivered and locking many students, often among the more vulnerable, into failure and financial catastrophe.  

It doesn't matter that the intentions were good.  It matters what the consequences are.  In the desperate pursuit of moral posturing we are doing grave harm to many of the most vulnerable purely for the social posturing of the Mandarin Class.
