If your company takes a pile of CVs and randomly picks a bunch of people to hire, then yes, you are absolutely correct, there is something very very wrong with company B if a truly random process results in an unequal distribution of hires.

But hiring isn't random. Maybe all the "brown" candidates lacked necessary qualifications. Or needed visas which they couldn't get. Or a million other reasons other than "org B is racist".

My point is: you need further context. To look at that one stat as given above and conclude org B is racist is....unwise.

Is that how you hire? You litearlly roll a dice for an interview? No bias of "This guy looks / acts / talks like me?"

I am not sure I have ever been on a team without some kind of like-me bias. It's real hard.

This is a very inappropriate analogy, because humans are very diverse; the exact opposite of a die's faces.

We’re not discussing f a human. We’re talking about fairly coarse demographic buckets
