MBTI type most difficult to understand?

[Grey Wolf]

For me,
it would be the ISTJs. I have no idea what they are thinking at all. doesn't make any sense to me. Doesn't mean they're bad people, just that I don't particularly get along that well with them as compared to others.

My gf is an ISFJ actually. We fight once in awhile, which is normal I guess, but other than that, we tend to use our dominant sides to our advantages. Like she will handle all the details and I will integrate the big picture. works quite well

Do you guys test a specific mbti all the time? I dont. I talked to my cousin who is a Jung analyst (yes I keep saying that because its bad ass and I bet you dont have a family member who is this) and he said that once you know about the test, it can influence how you answer the questions (obviously). I seem to be all over the board but a few things are ever prevalent. I never deviate from the I and the J etc...
