You can't do it perfectly but when you base hiring on objective skills you do better than when you base it on DEI.
When you doing it on a large scale you certainly can blind it. To reject that says you want to discriminate.
FFS: NO ONE hires on the basis sex, gender, race or religion.
That's your fantasyland, not reality. When you set out to find someone with criterion X you are hiring by that X. Just because it's not the only factor doesn't change this.
Until relatively recently virtually ALL hiring decisions included only a pool of white cis male, preferably Christian adjacent—except for jobs that were considered too menial, too dirty or involving too much hard physical labor or danger.
Continuing the discrimination doesn't fix the past discrimination.
WHY is it that people believe that Affirmative Action ever existed? It’s because persons of color and women and persons with ‘funny’ accents or religions were considered deemed not fit for the good, well paying jobs. Or if such candidates were undeniably the best ones for the job, hiring managers/bosses would ‘worry’ that customers would not react well, would not accept, would not trust a woman, a person of color, or non-Christian looking or obviously not straight or cis.
The original civil rights actions were proper. Discrimination was baked into the system, to be fair would put you at a disadvantage. That's long past, though, but the "solution" lives on, ever more desperate to prove that it's needed.
