This is where I'm going to finally explain the type of Carl Jung. For the purpose of this thread, I am only talking about specific socionics types, so that means I'll use LSI~ ISTJ, ILI~ INTP, EII~ INFJ, etc...
To start, let's consider how his creative function, Se, comes into play. For introverts, they use their creative function to find relationships and connections between subjects and objects. For someone with Se as a creative function, they become the best, must astute observers. They notice things with clarity, focus, and objection. They are the least likely of all the types to see something that isn’t there. They continue finding and exploring things until they see them often enough to believe in it. For a small definition of Se, I pulled this off of the site:
Experiencing and noticing the physical world, scanning for visible reactions and relevant data. You are one with the experience. There is no "naming" or describing - just pure, vivid experience. The whole scene comes into your awareness almost at once. You may be drawn to experience more and more, seeking any variation that will intensely excite the senses. Writing that is richly descriptive can also evoke extraverted Sensing as can other mental stimulation. The process is momentary and tied to the events of the iminediate situation. It is used in the here and now and helps us know what is really there in the physical world and to adapt to it. Extraverted Sensing occurs when we scan for information that is relevant to our interests, then we mentally register data and facts such as baseball statistics, the locations of all the restaurants in town, or the names of all the actors in the popular television shows. There can be an active seeking of more and more input to get the whole picture until all sources of input have been exhausted or something else captures our attention. Associated behaviors include eating a whole box of chocolates for the variety of tastes; playing an instrument for hours with pure enjoyment, not for practice; voracious reading or continual asking of questions to get specifics.
If you’ve read it, read it again so it clicks in your mind.
An example of someone else using Se as a creative function is Gregor Mendel (LSI), a 19th century monk. He spent much of his time observing plants and their traits. During his time, he was not even aware of such things as genes, but even without these he could not help but notice certain qualities and likeness between certain plants. What he was doing, in essence, was noting phenotypes without the knowledge of genotypes. To quote Dr. Andreasen on Mendel, “This Austrian monk was able to simply observe what happened to his peas based on experimental manipulation, and to deduce the principles of genetics . . . when he did not know that genes existed! All he could see were plants that varied on multiple traits . . . .”
This work seems to parallel that of Jung; separating people into 8 different functions.
Just to throw an odd piece of information out there, you can also consider Jung’s sex life. It was well-known that he slept around with several different women while he was married (and some of those women were kind of “crazy” too). Apparently, he was obsessed with hysterical, nymphomaniac women. This would just seem very uncharacteristic of an LII, whose fourth (weakest) function is Se. He would be attacking his own PoLR.
As for Jung being a dominant Ti type, I have read several times that he said himself that he was an Introverted Thinking type as he describers them.
If you read the Introverted Thinker, you will notice that Jung describes both a dominant function of Ti as well as a neurosis function of Fi. Knowing the types and his own system well enough and deep enough, it would make sense that he would know which type he is. The way he describes the different types it would be hard for him to mistake which one he is. Why would he think he has a neurosis function of Fi if his true neurosis was Si? Why would he think that he was dominated by a Ti if it really was Ni? Considering this, it is highly likely that he was at least LxI (with a dominant Ti).
Jung also called the thinking types RATIONALS, and since he thought he was a thinker he must have also considered himself rational instead of irrational. This would make sense, too, considering his work. Even his consistency of work would denote a rational (he finished some 40-odd books). The irrational types, such as ILI, often have difficulty with actually finishing and publishing their work, thesises, books, etc… Sometimes they get bored or distracted and move on to different things. Jung was also an analytical type of thinker (rational again). He talked about things such as “psychoanalysis”. Also, being able to place people into categories/boxes is much more associated with the rationals. Again, this is another thing that is just more difficult for the irrational types to see.
Now, it is inevitable that people are going to bring up Jung’s theory of the collective unconscious in defense of him being an intuitive (because “theory” is sometimes associated with intuitive). The difference is that sensors and intuitives will look at/ solve the same problem in different ways. Jung was a very persistent, determined and painstaking researcher; not one to rely on his intuitions to lead him. He wrote down and recorded everything that he saw, experienced, and what was told to him by several different people (btw, he was know to travel to and experience several different parts of the world to learn more- Se) and this is how he came to the concept of the collective unconscious. He started to notice undeniable patterns and consistencies in regard to dreams, etc… and only then could he come to this conclusion.
From a physical standpoint, I’d also like to share with you pictures of Jung. Notice here that he does not have a far off, intuitive gaze; rather, he has a stern, down to earth stare of the LSI.
“Anyone who wants to know the human psyche will learn next to nothing from experimental psychology. He would be better advised to abandon exact science, put away his scholar's gown, bid farewell to his study, and wander with human heart throught the world. There in the horrors of prisons, lunatic asylums and hospitals, in drab suburban pubs, in brothels and gambling-hells, in the salons of the elegant, the Stock Exchanges, socialist meetings, churches, revivalist gatherings and ecstatic sects, through love and hate, through the experience of passion in every form in his own body, he would reap richer stores of knowledge than text-books a foot thick could give him, and he will know how to doctor the sick with a real knowledge of the human soul.”
