This is an uncharitable interpretation of the comment about sexism & racism. I’m African American, yet the last time I took an implicit association test it showed I’m biased against African Americans. Yeah there’s a lot of conscious bias in the U.S., but we live in a culture with deep seated misogyny and racism that can effect even well meaning people.
This is a really good point. Women also show tend to show bias towards men, and gay men often show bias towards straight men. It's kind of an instinctual thing to suck up to the powerful.
I agree, however I think it's important that we do not use "implicit bias" as a cover. Implicit bias seems very vague and allows people to evade responsibility. I think there's a lot of very explicit bias (in the form of sexist attitudes, discrimination, biased hiring practices, etc) that need to be tackled. The "implicit bias" narrative (that a lot of tech CEOs are a fan of) makes me uncomfortable because it depoliticizes the issue, chalking it up so something more innately human (our biases and mistakes) rather than sexist attitudes and policies.
