Typing is an instinct, not a method
The instinctive approach is near useless. The only reason people engage in it is because they have a religious belief in their own abilities. They think that they are the next "typing messiah" that gets all the answers right just by guessing at them. Meanwhile, everybody reaches different conclusions on any person's type when applying the "vibe-typing" method. If in such a situation only one person can be right about the type, it follows that the rest of them are terminally deluded. Add to this the fact that the person that is "right" across different cases is not even always the same person, and you get a really dismal view of the sanity of people who engage in this childish game.
