I never said that minorities can only be hired by applying insufficient scrutiny. What I will say is as a group, minorities can only be hired in a proportion that is different to the proportion of minorities in group of qualified applicants if some weighting is taken off the job relevant qualifications, and applied to their membership in minority groups.
If you could come up with a huge list of entirely fungible, interchangeable resumes and interview notes, you could consciously pick minorities first without harming the quality of your recruiting. What kind of roles would have that weak of a job market though?
If candidates aren't fungible weighting any importance to race/sex means taking some weighting off something else, and it means that bigots will assume individuals from minority groups are less qualified, because of the fact that the group as a whole is less qualified, because of your own policies. It perpetuates both inequality and bigotry.
If we had some way of scoring candidates numerically, then yes, you'd just pick the biggest number. But I've never heard of a hiring system that worked like that. There's always some subjectivity. You can look at a bunch of resumes and rank them, but a good chunk of that ranking is guesswork and opinion. That gives room for your biases to play, and you'll end up with the "best" candidates tending to match those biases. And don't tell me you don't have any racial or gender biases; you do, everybody does.
You shouldn't give up a 9.9/10 because he's white, and hire a 2.4/10 because she's black. But if you have a bunch of candidates around 8/10, consider hiring the minority candidate who's a 7.9 rather than the candidate who matches the existing demographics of your team and is an 8.1. Your numbers are probably ±3 anyway, so it's not the irrational decision it sounds like it would be in a universe of pure numbers.
I'd like to know how you even begin to judge what ethnicity someone is just by looking at them. Sounds like an extremely fraught game to play.
Part of the answer is surely to try your utmost to take all the subjectivity out of the process. I've mentioned it here previously, and people said that they enjoy getting to make subjective value judgments of candidates. I think that is a poor attitude.
This is the kind of process I was thinking:
One person strips CV's of irrelevant info (names, ages, schools, etc). They hand that to another person who decides who to interview. When the candidate is interviewed, pre-determined questions get asked, and then notes are taken of their answers and any relevant info, and that gets handed over to the person who makes the ultimate hiring decision.
Even that process probably leaks a bit, but it's better than simply trying to guess.
Your idea sounds great too. I think there's still room for error there, in how the questions are formulated or answers interpreted. Think a mild version of the old Jewish Problems. But it could certainly make things a lot better.
And the assumption that minorities can only be hired by insufficient scrutiny is not a very enlightened attitude. Perhaps the company can look really hard for qualified candidates that help balance the workforce. How about that?
I agree that real progress is the right way to evaluate hiring/ admissions programs. Do qualified people end up in a diverse student/worker population? Then you're doing it right.
