Clarifying "Preferences" in MBTI:
"Preference" is not defined as desire in MBTI, it is defined as nature or "default setting". Not what you do, but what is most natural and comfortable for you to do. Jung believed a "default" mode, basically, would rise up to the surface like a beach ball submerged under water if suppressed by situational or environmental factors. Some mistakenly believe that MBTI type is based on what you want to be, since it is not about strengths / weaknesses, but this is not what has actually been taught by the original theories.
So focus not on what you are able to do (you do both), but what you default into naturally.

"Feeling" is not the same as "Emotions / Emotional"
"It is important to recognize that feeling should not be equated with irrationality. Indeed, Jung went out of his way to ensure that thinking and feeling were approached on equal grounds, classifying both as 'rational' functions. Jung also took care to distinguish the feeling function from emotions, essentially saying that the feeling function is charged with evaluating emotions." -Dr. A.J. Drenth
You shouldn't be typing yourself as a Feeler simply due to the fact that you see yourself as an emotional human being. Ts aren't robots.




Extroverted Feeling
Extroverted Feeling’s value judgements are largely dependant on the outer world. This might seem seem strange, since feelings are usually seen as inherently subjective things. With this type, insofar as her Feeling is extroverted (and there is a spectrum!), it’s in harmony with the traditional or generally accepted values of the time. It’s also influenced moment-to-moment by its peers. The criteria for its judgements come from all kinds of external conditions. For example, a painting, regardless of how good it really is, might be called beautiful because it’s the work of a famous and well-loved artist, or because calling it anything worse might ruin the atmosphere or offend the owner. These aren’t lies, but merely an act of adjustment.This type follows her feelings as a guide throughout life. Since her feelings are oriented by the outer world, they harmonise with her current situation and its general values. She seems thoroughly adapted to her social environment. In a healthy type, her feelings still have a personal, genuine element at their core, however much it’s masked and modified to accommodate external conditions. For example, her love interest tends towards the suitable person with a good and conventional nature, rather than someone who satisfies hidden desires. This also isn’t a lie – it’s her real feeling of love, regardless of how impersonal her choice might appear.

Introverted Feeling
Introverted Feeling’s value judgements are oriented by the inner world and the collective unconscious. It has a passionate tie to these inner images or ideals, as if it were chasing a dream or vision it had once upon a time. The goal isn’t to relate itself to the external environment, but to bring these inner ideals to life through Feeling. It glides over anything in the outer world that doesn’t match its subjective values; as a result, its valuations rarely appear on the surface, and the ones that do are usually negative, as if it were trying to ward off or discourage the object. For an observer, a positive feeling has to be guessed at indirectly.Her relatively neutral, reserved demeanour might make it look as if she has no feelings at all – in reality, she finds expressing herself difficult, and so her passion and sympathy grow all the more intense. Inside, the sorrows of others become a whole world of misery – “still waters run deep”. She might eventually burst with feeling, perhaps in a way that seems extravagant or inappropriate, partly since her feelings are adapted to the archetypal forms of the collective unconscious and represent more than just the current situation. Normally her passion trickles out, secret and well-hidden, in religiousness, art, poetry, or intimate relationships.

Extroverted Thinking
Extroverted Thinking is a type of mechanistic reasoning that is primarily oriented by external conditions and objective facts. As a result, it’s generally conscientious and quick to meet the demands and challenges presented by the outside world. Its external nature doesn’t mean that it only deals with concrete things – it can also be totally abstract, but the abstract concepts it plays with tend to be learnt from education, or borrowed from the intellectual culture of the time. It tends to concretise ideas and lead them into the outer world. Its conclusions should have some some objective effect or relevance, they should be externally applicable in some way.
There is no difference between the logic employed by Te and Ti. The differences lie in the preferred type of data and the preferred way of shaping ideas, as mentioned above. Te operates most cleverly and effectively when it has a lifeline to facts and generally accepted ideas, which it shapes in productive ways. This might give a pessimistic observer the impression that Te is restricted and “inside the box”, when in reality it has an an impressive creativity and capability in its preferred realm.
However, when objective facts and borrowed ideas become so important to Te that they overwhelm the subjective thought process completely, it loses its creative spark. It’s hardly Thinking anymore, as it only serves to reflect what is already obvious in a set of data and never goes beyond it. It will not even try to compare the ideas with the user’s own past experiences, which remain dissociated and useless in his psyche for lack of an intellectual link.


Introverted Thinking
Introverted Thinking is mechanistic reasoning guided by subjective tendencies that have their roots in the collective unconscious. This subconscious influence might manifest as a vague sense of structure that guides logic, or a more or less complete idea that only needs to be intellectually formulated. In either case, the theories that Ti creates aren’t derived from external facts, however much the Ti type would like that to be true in the name of being “objective”. The idea has its roots in the psyche, and facts are only used to confirm it or provide evidence of its validity.
However, Ti has the dangerous tendency to give the subject too much credit, at which point it might twist and mangle the facts to fit a subjective theory, or ignore them completely and engage in a kind of intellectual fantasy. This Thinking starts to show a mythological streak, the result of its basis in the collective unconscious. The strong convictions of the Ti type come from the evolved validity of these “eternal truths”. However, their value is lost as long as the Ti type neglects to link them up with objective facts and ideas.
Over-introverted Ti risks creating ideas that say nothing real or relevant. By contrast, over-extroverted Te risks becoming nothing more than stating the facts. Ti says, “I think, therefore I think,” while Te says “It is, therefore it is”. If this intensification continues, the Ti type’s outer life goes to another function in the unconscious, usually Feeling. His relationships with people and things will be infected by childish complexes, fears, anxieties, and the negativity characteristic of the unconscious.


Extroverted Intuition
Extroverted Intuition is directed towards things in the outer world. Intuitions are the result of subconscious processes, which appear in conscious awareness as a sense of expectancy, a vision, or an idea about the outer world that isn’t obvious from the visible facts. When Ne is dominant, it (like Se) doesn’t only perceive the world, but participates in it and creatively shapes it. Since Ne does this in part unconsciously, it also affects its peers through their unconscious.
Ne shows its user perceptions about things, and relationships between things, in a way that the other functions might only do in a roundabout way at best. They represent insights and future possibilities, and these hunches – while uncertain in their origin – have a decisive influence on the user’s behaviour. As an auxiliary function, Ne is what looks for a way out of a hopeless situation when every other function is stumped. When it is the dominant function, everything in life is like a locked room that must be opened. Objects and facts have an exaggerated value if they seem to offer a solution, a way out, but as soon as they fulfil their promise of novelty, they are dropped and forgotten.
The Ne type chases possibilities for their own sake, since (unlike Se) possibilities (and not sensations) represent the fullness of life. Some sensuous experiences might still be extremely compelling, but only if they hold the potential for new avenues of possibility. In general, the Ne type represses the other functions, especially Sensation, since it represents the “surface” of things that Ne is trying to peer behind.


Introverted Intuition
Introverted Intuition is directed at the contents of the unconscious. However, just as our senses only give us an approximate image of the objective world, so does Ni give an approximate image or impression of the inner world and its contents. Although it may be triggered by an external stimulus, it doesn’t focus on the external possibilities, but on what images are released in the psyche. Unlike Si, these images don’t concern the course of sensations, but their underlying causes or hidden meanings. However, since the Ni type represses Sensation, he rarely manages to connect the resulting hunches to himself or his bodily existence, instead seeing them as if they had an objective existence of their own.
Just as Ne chases every possibility in the outer world, Ni chases every image that arises from the inner world, “the teeming womb of the unconscious”. Again, the Ni type doesn’t connect them to himself, and since he’s only concerned with perceiving them, he isn’t impelled to shape them into rational judgements like Ti or Fi. The latter are also only affected by the images subconsciously – by contrast, Ni seeks to explore every detail of them, with the same clarity that Se has with respect to the outer world.
Ni is the function which is most intimately connected with the collective unconscious. The archetypal patterns, which have evolved over millions of years to represent eternal patterns of life, are the main source of the insight which Ni often provides. Its tendency to project into the future is thanks to an almost direct consultation with these archetypes. If paired with Feeling, it has the potential to paint a more or less complete picture of another person’s psychology.


Extroverted Sensation
Extroverted Sensation is a perception of the physical world that is more concerned with the objective qualities of a thing than what it means to the user. Se is a conscious function when sensations are not just being processed subliminally, but are actually being noticed and made aware of. If it’s an inferior function, sensations will only be consciously noted sporadically, but if Se is dominant, no part of the environment is overlooked or excluded.
The personal, subjective attitudes and associations the user has about sights, smells, sounds, etc. are minimised. For Se, the factor that makes a sensation really compelling is inherent in the object itself. It’s interested in what kind of exciting sensations the physical world can offer it, the “highest pitch of actuality”. As a result, it has a strong and instinctual tie to material reality, which becomes the deciding factor in the Se type’s activities and choices, superseding the rational judgements of Thinking or Feeling.
Se is interested in things that roughly everyone, everywhere, would sense as real and concrete, and takes great enjoyment in experiencing them to their fullest. The judging functions are relatively suppressed in favour the facts that Sensation plainly sees, but Intuition is suppressed most of all. It takes on the negative and childish characteristics of the unconscious.


Introverted Sensation
Introverted Sensation is a perception of the physical world that is more concerned with the psychological reaction to objects than their objective qualities. This subjective part of Sensation is most easily demonstrated in art; even a still-life scene will be painted differently from artist to artist, in terms of their treatment of colour, form, and mood. The Si type pours his personal, subjective attitude into his perception of the concrete world, and subsequently behaves as if he were seeing something quite unique and different from what’s actually there.
Si’s perceptions are too organic and genuine to be a product of consciousness. Instead, the subjective factor of sensation is a spontaneous product of the unconscious. It is representative not only of the user’s past experiences, but also the underlying elements of the collective unconscious. The Si type’s perception of the concrete world is adapted to the “eternal truths” – archetypal or even mythological patterns of life.
Si, in a sense, sees the background of the physical world. The important thing isn’t the object, but its mirror-image in the psyche. Objects don’t only appear in their present instance (as Se sees them) but also with a vague sense of their past and future, “somewhat as a million-year-old-consciousness might see them”. Si covers the concrete world with a shroud of meaning, subjective experience and archetypal forms.

Thinking refers to how people make decisions. Thinking people are objective and base their decision onhard logic and facts. They tend to analyze the pros and cons of a situation and notice inconsistencies. They prefer to be task-oriented and fair.

Feeling people are more subjective. They base their decisions on principles and personal values. When making decisions, they consider other people’s feelings and take it in account. It is in their best mind to maintain harmony among a group. They are more governed by their heart (Myers 65).

Sensing refers to processing data through the five senses. Sensing people focus on the present and prefer to “learn by doing” rather than thinking it through. They are concrete thinkers recognize details. They are more energized by the practical use of an object / idea rather than the theory behind it.

Intuition refers to how people process data. Intuitive people are keener to the meaning and patterns behind information. Intuitive people aremore focused on how the present would affect the future. They are readily able to grasp different possibilities and abstract concepts. They easily seethe big picture rather than the details (Myers 57).
