Sure, everybody is biased in many ways. I am not claiming I don't have any bias, but those become irrelevant if you make an effort to decide things rationally.

Sure, everybody is biased in many ways. I am not claiming I don't have any bias, but those become irrelevant if you make an effort to decide things rationally. And in my opinion, when judging other people, we should always make sure we're basing our decision on rationality, not what feels better to us. This obviously requires some work to train yourself to notice when you're lying to yourself or making up reasons to go with the decision that feels better when you should really know it's not the correct one.
