Your response imposes a specific view of "systemic equity", one that not everyone buys into, and one that has not been empirically verified. Furthermore, the author has consistently blogged about his support for affirmative action, so I'm not sure your rhetoric makes any sense.

The notion of bias being self-enforcing is questionable as well. Unconscious bias here seems like a catch-all for any kind of perceived injustices. For all you know, the effects of unconscious bias could have been reasonably mitigated by education, personality, and sound policies. I'm not stating that biases don't exist, or that they are inconsequential. My point is that using unconscious bias as a catch-all is not intellectually honest as it gives unearned merit to claims made without evidence. The way forward is more empirical work, not more rhetoric.
