Rationality is supposed to be a reference to a person's ability to think through their situation. Since all people have limited and subjective human perspectives, it's reasonable to suspect flaws within everybody's rationality. This doesn't mean that "rationality" should be dismissed as meaningless work, it just means we need to understand that it is the nature of humans to be less than perfect in how we act and think. As for me, I always make sure to distinguish fact, conjecture, and opinion. I always make sure to distinguish that all people have hidden (unconscious) motivations that affect themselves.
