Evidence says no, by my reading of the evidence in this case. /THREAD
David Card has does the statistical analysis on this for the defense and, unsurprisingly, it is airtight. 5/N
He is the top applied micro-economist in the world, IMO. 6/N
The plaintiffs also do stats modeling but leave out key variables in the process.
Plaintiffs’ rebuttal of Card’s analysis is here
David Card and Peter Arcidiciano are both gems with stellar research records
I avoid being a paid expert witness so that I retain complete freedom to shoot my mouth off
Unsurprisingly, it's not as nuanced as analyses by Arcidiciano and Card. 16/N
By leaving it out they toss a lot that goes into admissions. Nuance about lives and the challenges kids face. Kid lost parent at young age, sibling is incarcerated. 21/N
Plaintiffs complain that they were not provided essays and letters of rec. Yo, maybe the applicants have some right to privacy here?
Asians score LOWER than Whites on personal rating! 😡
READ THE EFFING BRIEF
Asians score HIGHER than Whites on academic & extracurricular ratings 🤔
The previous 23 tweets in this thread provide that critical context.
Going to explain the methodology here (& reiterate my hatred for the metric’s moniker)
They use identical models but interpret the results differently.
“How much of the summary ratings is explained by the variables we see (=“objective”)?
How much of the summary ratings is NOT explained by the variables we see (=“subjective,” perhaps a channel for discrimination).
(Nerds: a dummy var for Asian has a negative coeff)
Plaintiff’s interpretation: bias against Asians
A consistent reading of the results would say that THIS is evidence of bias IN FAVOR OF Asians.
Unexplained, LOW ratings for Asians indicates discrimination against them while unexplained, HIGH ratings for Asians indicates Asians must be better in ways we can’t see.
