Go back and re-read, senza. That wasn't the test. This was just an exercise afterward to teach us about the dichotomies. And they didn't seem that great to me, but these were the official MBTI people, for whatever that's worth (not much)
I just don't think people should be taught to mistake introversion for intuition. Offering personal perspectives doesn't necessarily make people intuitive, especially when they're on the level of "I think M&Ms are sweet and crunchy."
