What fun! I'm INTJ (100 25 38 78). I've taken this test over the years and I can tell that my type is changing. I was never 100% introverted before. It's because I'm getting older!
I'm also INTJ 89-75-12-67. :)
Maybe that's what's happening to me as well. I used to be an ENTJ, now I'm an INTJ. I don't think I'm all that introverted, but I sure can't be bothered with people as much as before!
