When I was seeing an INTJ, he told me that he had to change his usual way of perceiving, he became quite sensitive to every little thing. He said, though, that it'd be exhausting to do that all the time.Do not underestimate our minds. What I mean by this is that the blind spot can be overcome. Know that we have the ability to willingly change our personalities and therefore we are allowed to see the views and perspectives of the other personality types. I'm not so sure if we can permanently change it though.
Of course, I believe we can learn new skills and even, traits. I have noticed that whenever I get to know another type well, I can often mimic their characteristics, if I like them, that is. I even talk like they do, which is very strange to me. I don't know why that happens, except I find it great fun to pick someone apart and learn who they are at the core. That's why I can't watch movie after movie because I absorb so much and try to analyze everything. Even the less cerebral movies like Yes, Man, I gained moral inspirations from, hahaha.
