Strong agree, all the parts. And sympathies.
I note that I was focused on my personal beef (“What works?”) and missed the other half of your message (“What scales?”)!
A happier thought to temper all that: I’m a big believer in the power of awareness. Even if we don’t have a scalable intervention for implicit bias, having lots of people realize it exists can still have a big positive impact. (And then, yes, we have to educate that not all bias is implicit…)
