As I said before, one would hope that the committee would have had some sort of training on biases to know that A doesn't always imply B. You're capable of making that distinction, I'm capable of making that distinction, why are you so quick to say that an adcom member wouldn't be able to make that distinction?
Impressions matter and are not quantifiable. Humans want to be fair but our implicit biases are hard to get rid of even when we know that it's there. Many experiments have showed just that with white-black relations.
