Jung first divided psychological types into two types: extroversion and introversion. He also divided human personality into eight types according to the four functions of human psychology - thinking, emotion, feeling and intuition.

1. Extraverted Sensing Type

The only thing people of this type value is sensory objects. They are keen on accumulating experiences related to the external world. They are realists, pragmatists, and clear-minded, but they do not pursue things too deeply. They see life as it is and do not give it their own thoughts and foresight.

But they can also be those who dare to enjoy themselves and pursue excitement. They lack rationality and their emotions are relatively shallow. Their whole life is just to get every feeling they can from life. The typical extremes among them either become crude indulgents or exaggerated aesthetes. They can indulge in a variety of different types of hobbies, have perverted and compulsive behaviors, depending on their sensory tendencies.

This type is mostly male.

2. Introverted Sensing Type

Like all introverted people, introverted feeling people also stay away from the external objective world and are immersed in their own subjective feelings. Sometimes , they will be troubled by the collective subconscious representation and cannot bear the various impressions from the outside world. They need more time to absorb and understand these impressions. They may also suffer from difficulty expressing something that is a hallmark of introversion.

Compared with their inner world, they feel that the external world is dull and lifeless. There is no other way to express themselves except through art, yet the works they create often lack any meaning. They also lack rationality and have underdeveloped emotional functions. To outsiders, they may appear calm, easy-going, persistent, and self-controlled, but in fact they are often not very interesting people due to their poverty of thought and emotion.

This type is mostly male.

3. Extraverted thinking type

People of this type direct their thinking towards the external objective world, are interested in facts, and are easily attracted by objective thinking, making objective thinking rise to dominance. The passion of his life. They can put feelings and emotions aside and ignore them, insisting that the flow of thoughts starts from objective known materials and returns to these materials. In other words, external reality is the cause and purpose of their thinking.

The typical example is scientists. These scientists have dedicated their lives to understanding as much as possible about the objective world. Their goal is to understand natural phenomena, discover natural laws, and create theoretical systems. Darwin and Einstein were most fully developed in the direction of extraverted thinking. People with extraverted thinking usually tend to suppress the emotional side of their nature, so in the eyes of others, they may appear to lack a distinctive personality, or even appear cold and arrogant.

If this repression is too severe, emotions will be forced to adopt circuitous or even morbid and abnormal ways to affect his character. He is likely to become stubborn, conceited, superstitious, and not accept any criticism. Lacking emotion, their thoughts can easily become dull. The most typical and extreme of such people is the so-called "academic maniac", or he periodically turns into a mentally abnormal monster, the so-called "Frankenstein".

This type is mostly male.

4. Introverted thinking

People of this type are introverted in their thinking. They are not interested in facts but in ideas. The main quality is to look at things in a different way, to create some new physics and new perspectives, and to put forward in-depth opinions. For them, external facts are not the purpose, but just examples to prove their concepts.

Philosophers or existential psychologists fall into this category. What they wish to understand is personal existence. They pay little attention to the external world and are often absent-minded about the people and things around them. They will attract attention at inappropriate times. They are shy and taciturn or have abrupt reactions when they are with others. When they are alone, they forget where they are. In extreme cases, the results of their self-detection may have little to do with reality, and in the end they may even cut off the connection with reality and become mentally ill.

They share the same personality traits as many people with extraverted thinking. Because like people with extraverted thinking, they also have to protect themselves at all times from the turmoil of suppressed emotions in the unconscious. They often appear cold and unfeeling because they do not value other people.

They long to live in isolation so that they can indulge in fantasy. They don't care whether their ideas are accepted by others. Although they probably have a few of their own type as their true followers. They can easily become stubborn, self-willed, and not good at understanding others; they can easily become arrogant, sensitive, irritable, and alienated from others. As this tendency intensifies, the repressed emotional functions are likely to exert an influence on their thinking in perverted and fanatical ways.

This type is mostly male.

5. Extraverted Emotional Type

This type of person subordinates reason to emotion, is easily restricted by objective external standards, and is often controlled by the environment in which he or she lives. They have good adaptability and can develop in harmony with the world.

They will stick to their existing values, have a strong sense of history and tradition, and are good at handling interpersonal relationships. These people are very popular in group activities. Everyone likes to get along with them and think they are enthusiastic. Competent, charming, moral, and feel they are sincere in helping others.

The other extreme makes people feel shallow, hypocritical and dehumanized. This is caused by their excessive suppression of thinking function. The thinking ability of these people is not developed.

It is more reflected in women. Because their emotions constantly change with changes in the outside world, they often appear capricious and capricious. Any slight change in the outside world may cause changes in their emotions. They are often sentimental, showy, overly attentive, and strongly attached to others (this attachment is often short-lived). Their love can easily turn into hate. There is nothing new in their emotions, they are completely A set of clichés, they are always willing to follow the latest trends.

Usually, people of this type can find a good partner relatively smoothly.

6. Introverted feeling type

This type of person is usually more common in women. They are most susceptible to interference from subjective factors and are dominated by subjective feelings. Will focus on inner emotions, which are inspired by some primitive emotional images, so they will show original, unusual and creative characteristics. This type of person no longer pays attention to the external world, so he or she is less adaptable.

They don't show off their feelings like extraverted feeling people, but keep it deep inside. They tend to be taciturn and elusive, with an easy-going and cold attitude, and often have a melancholic and depressed demeanor. However, they can also often give people an impression of inner harmony, tranquility, and contentment, and they often appear to have a mysterious charm in the eyes of others. They are the kind of people who say "when the water is still, the depth is deep".

In fact, they do have some deep and strong emotions, but they are not good at expressing them. Their creativity will be reflected in literary and artistic works.

7. Extraverted intuitive type

People of this type are characterized by whimsical and moody. They jump from one state of mind to another in order to discover from the external world New possibilities and novelties are very important to him. Those are the driving force of their lives. They are unwilling to endure the unchanging facts and have a rebellious spirit. Customs and religious laws do not have much binding force on them. When they are focused on pursuing new things, their sensory beliefs cannot influence them at all, but they also have morals and beliefs based on their intuitive and reasonable opinions.

Due to lack of thinking ability, they cannot follow a certain intuition tenaciously and diligently for a long time, but have to leap to a new intuition. They can make special contributions as promoters and initiators of new enterprises or undertakings, but they cannot always maintain their interest there. They tend to waste their lives on a series of intuitions, and hand over their discoveries and innovations to others without hesitation, but in the end they achieve nothing.

They are not reliable friends. Although they are always very enthusiastic about the various possibilities that will result from each new interaction with others, they often inadvertently hurt others due to their lack of lasting interest in the interaction. . They have many interests and hobbies, but soon get bored and give up on them. It is often difficult for them to stay engaged in one type of work.

This type of person is not prone to sadness.

8. Introverted intuitive type

This type of person is committed to looking for possibilities from the inner spiritual world. Jung believed that "the world of introverted intuition is the collective unconscious, the background of obscure experiences, that is, all that is subjective, strange, and bizarre to the extrovert."

The most typical representatives are artists, but they also include dreamers, mystics, and eccentric people full of hallucinations.

Introverted intuitive people are often seen as incredible people by their friends, and they themselves often see themselves as geniuses who are not understood.

Since they have nothing to do with reality or tradition, they cannot communicate effectively with others, or even with the same type of people. They are trapped in a world full of primitive images, the meaning of which they do not understand. If introverted intuitive people are dreamers, they will identify themselves in fantasy and immerse themselves in intuitive meditation; if they are creative artists, they will be good at changes from perception to shape, and will show something to the world in their own way. Extraordinary and strange things that are at once solemn and ordinary, beautiful and weird, sublime and ridiculous.

Like extraverted intuitive people, they jump from one image to another, always looking for new possibilities. But all their efforts never allowed them to develop further beyond the scope of their intuition. Because their interest cannot remain in one image, they cannot make as profound a contribution to the understanding of mental processes as introverted thinkers do. But no matter what, they have colorful intuitions that others can think about, organize and develop.
