I think it's important to understand that while everyone has conscious and unconscious biases, it's not true that recognizing that fact is the same as assigning blame. The idea is to better know one's self, to try and understand one's own bias (to the best of one's ability, that is) in order to try and apply correctives when making decisions involving people who are different than we are.

It's when we actively press into these biases that we hold and steadfastly cling to them in the face of contrary evidence that we become guilty.

Now I'm not claiming that having bias is a good thing, it's quite the opposite. I am saying, however, that having bias does not imply culpability.
