> So when faced with a resume, I know that the non-diverse candidate got there on merit alone. But the "diverse" one? Maybe it was merit, maybe it was the quota... Why should I be the one to take the risk?
So the white candidate benefits from your attributing their career progress to merit alone, while the non-white candidate has to work extra hard to convince you, and every other potential interviewer, in a short amount of time that their career progress was legitimately earned. Maybe they'll be able to persuade you, maybe they won't. You might consider yourself to be unbiased and just doing a basic risk assessment ("Why should I be the one to take the risk?"), but maybe other managers would really just prefer to work with other white people, using thin excuses like "better culture fit."
Let's say that this type of bias leads to 10% fewer offers being made toward a non-white candidate than a comparable white candidate. Now multiply that by the number of interviews a person needs to go through to amass a decent amount of experience in their field. Think of the compounding effects!
This is exactly why we need programs that prioritize diversity in hiring, to try to chip away at the biases that non-white candidates often face.
