I think that's one of the best analogies I've read on this. I believe especially the unknown biases are a problem. Many companies don't know why they hire less diverse, so they either deflect it (e.g. by blaming universities) or they introduce quotas. Quotas might be the best thing in this situation but ultimately, only finding and rooting out biases can lead to a truly fair process. Especially since quotas only work in large numbers. Hiring for upper management, in niche roles or in small companies cannot be accomplished fairly with quotas.
