I wonder how MBTI would be perceived if instead of simply a binary EI/NS/FT/PJ, anyone within a standard deviation of the mean got an X, so you could be INXX if you were solidly introverted and intuitive, but not particularly strongly aligned on the later two axes. Naturally most people would have at least an X or two, but it would be much more useful if people didn't have to advertise an F or T if it didn't really matter for describing them. Though it probably wouldn't have caught on. Who wants to be the XXXX in a situation.
