Hm, I suppose I relate to that. My thought process is similar. I determine someone is type X. I think, oh, that's why I didn't get that person, they have a completely different thought process from me. I may not ever completely understand them, but it helps me understand them to an extent. If I can see that, I'm no longer thinking, that's irrational; it's just different.
This understanding into other people is why I love studying typology and psychological theory
