This is a subtle point but worth stating -- AI does not mirror or copy human reasoning.

AI is designed to get the same results as a human. How it gets to those results is often very, very different. I'm having trouble finding it, but there was an article a while back trying to do focus tracking between humans and computers for image recognition. What they found was that even when computers were relatively consistent with humans in results, they often focused on different parts of the image and relied on different correlations.

That doesn't mean that Amazon isn't biased. I mean, let's be honest, it probably is; there's no way a company this large is going to be able to perfectly filter or train every employee and on average tech bias trends against women. BUT, the point is that even if Amazon were to completely eliminate bias from every single hiring decision it used in its training data, an AI still might introduce a racial or gendered bias on its own if the data were skewed or had an unseen correlation that researchers didn't intend.
