It just hit me today, after much observation, that people with the exact same personality type tend to avoid each other and, in general, rub each other the wrong way. For example, in my community there are two brilliant INTJ's who are almost exactly the same in interests and personality. But they can't stand each other, and constantly denounce the other one publicly.
My mother, an ENFP, knows two ENFP's and avoids them like the Dickens. When I mentioned to her the similarity in MBTI, she got nervous, and started finding all sorts of differences between them and her.
Finally, there's my younger sister and I, both INFP's. I think she's a great person, but I dislike talking to her because there is no dynamic happening between us at all. Plus, it feels strange- as if I'm talking to someone copying the things that make me unique.
Anyone else have this? Does it make sense?
