But I don't see much difference between his psychological types (another of his great ideas) and how they are used in MBTI. MBTI is all based on Jung's ideas. Myers and Briggs took the description of the types and faithfully developed the test to elucidate them. There is no question of persona vs. psyche in regards to MBTI vs. Jung that I can see. Maybe you can tell me what you see Odin a bit more.
(and he was certainly INTP by the time he came up with his Types-- as purely an N activity as you can get-- as the commentator Odin quoted pointed out)
What I see are misinterpretations, coming from both Jung and Myers-Briggs and all the commentators and psychologists who use them. It doesn't matter whether these misinterpretations are from Jung himself or from Myers-Briggs and their practitioners. If they are from Jung, that does not make them more psychological; they are still wrong (such as the idea that feelings are about values).
First, there is a tendency to treat the functions like they were chemical or mathematical formulas, and use them that way in a system. But they are not like that. They are like colors or tones; parts of a whole like members of a symphony orchestra, not separate parts of a machine. Fe and Ti and so forth are not elements of a system. The functions are just different shades of the same thing: the soul or conscious being of the individual (which itself is part of the larger collective soul). All the hierarchies of dominant and auxiliary and recessive functions are invalid, therefore. Introverted people don't act from a dominant function hidden in an introverted way, then turn to an auxiliary function to project into the world extraverted. That is a nice model, but I think it's just a fun fantasy. If someone is introverted, they are usually introverted in all their functions, and extraverted less often in all their functions. Which functions are dominant and which recessive are indicated by the scores on the test. Making human psychology into an elaborate system with separate parts like a machine is invalid, however fun and popular it may be.
But that doesn't change the essential correctness of the description of the functions (NSTF) and energy modes (EIJP) themselves, and the MBTI reflects them perfectly well in my opinion. If you want to know what the functions represent in themselves, just take a look at the MBTI test questions. There is a dominant/submissive relationship between T and F, and between N and S, I grant that, but coupling that with extraverted and introverted as separate parts is where I think the system goes off track.
I already mentioned that the systemizers do the same sort of thing with J and P as if it could determine dominant function, rather than just indicate an energy mode or lifestyle in itself. Then from Jung they take the also-mistaken idea that N and S are "irrational" perceiving functions and T and F are "rational" judging functions. I don't buy that either. All the functions are ways to receive and process information. We make decisions using our J mode, on the basis of info supplied by all 4 functions, or any one of them. There is no basis to say two of them are perceiving functions and two are judging functions, especially when the actual questions on MBTI for J and P have nothing to do with those functions, but are about whether you are ordered and scheduled or open-ended and exploratory. Any of the functions can operate in either way, so there's no basis for calling them one or the other. Again, they use this idea to develop the hierarchy of dominant and recessive functions like pieces of a machine; I say it is bogus.
