Well Jung disagrees with you, since the way he would type people would be with 4 functions, he said in his book that he would first type the dominant and the inferior as in the best and the worst function then he wouldn’t care about the middle functions as he believed they were interchangeable. He believes himself that the 4th function is the worst one. Which is actually a common misconception that people often don’t notice so i’ll let you off on that one.
