Honestly, I think we are arguing around each other. We simply read this notion totally differently. You're taking it to mean that "we can't correct bias" but the statement was "we can't avoid bias". It actually makes no comment on being able to correct it (within, or without ourselves). To me it read as "when interacting with the world, we can't avoid encountering bias". If this is how it is interpreted, it actually doesn't do anything to rule out the ability to account and correct for it.

I'm not saying there's a definitive interpretation with how terse it is, just that we aren't necessarily on the same page and attempts to come to any sort of agreement with each other might be a waste of time as we are practically talking about two different ideas. I take this response as pretty fair, and I think the point you're making is totally valid, I just think our respective ideas would never converge as we are talking about 2 distinct things. (Interesting how much conversation a lack of clarity can generate).
