Author would suggest lowering the bar [for women] would only reinforce such stereotypes, do you agree or disagree?
Of course the trick is that you don't need to see the candidates or talk to them, just listen to their playing. In software, we would need to find some similarly effective way to measure anonymized performance.
In fact, completely aside from fixing gender and racial biases, that's something we could really use just to make good hiring decisions! I don't believe anyone really knows how to make consistently great hires in software.
For a start, the hiring decision could be based on gender-anonymized feedback from the interviewer(s), although that obviously wouldn't fix any underlying biases in the feedback itself.
I think their results were confusing and uncertain, but the methodology seemed brilliant and I think should be the gold-standard for tech interviews. If we keep it phone it would remove other subliminal biases (attractiveness, physical disabilities) as an additional benefit.
Other than doing thought experiments to try to correct for biases... It's hard.
One thing, and it's a small thing, is noticing if people in a group seem to have something to say, but seem unable to say it because they won't interrupt/talk over people (or that keeps happening)... Once you notice it, clearing a space for them to actually talk can help.
It requires being tuned in not just to the conversation, but the people in it, which is itself difficult. But I have seen it happen and it can be powerful.
There are a lot of little things like that which can be worked out, and I have no list of them or any magic wand solution.
Basically? Pay some attention to your biases and how you - and those around you - are treating others, especially those who might have internalized negative stereotypes and be struggling with imposter syndrome and all of that. Emotional awareness really helps.
