The plaintiff claims he was rejected for non-meritocratic reasons (racial discrimination), and offers as proof his 1. GPA and SAT scores (very good but hardly singular in the elite applicant pool). 2. A few intangibles. "See? I'm a great coder! I even got a job for it!"
There is no way to boil down intangibles into numbers, plug those numbers into an equation, and yet that the result of that equation be representative of an idealized concept of "meritocracy." The people who make the equation might claim that they're being quantitative and objective, but their biases can't be separated from the result. i.e., "What matters for determining the applicant's quality is what I believe should matter."
Ultimately, measuring merit can never be done with absolute precision, so long as it's other humans determining the criteria. We would would need an AI with beyond-human intelligence. Something that can look at the totality of who we are and what we can become. Something that knows us far better than any human can know another human. (a chilling concept to me, but whatever)
So...what do we want here? Do we want to revolve all college admission and the course of a person's entire life around a single test, like the Chinese gaokao? Asian-style test structures become all-consuming and are probably a major contributor to the collapsing birth rates over there. We've never had that in the Western educational environment. Or most of the rest of Western society for that matter.
Or do we want to continue to consider intangibles, like we always have? Legacy admissions, athletic admissions, race-based considerations. Should they all go? Personally, I see some value to all three, from a financial standpoint, a cultural standpoint, or both.
