According to Carl Jung's typology all people can be classified using three criteria. These criteria are:
Extraversion - Introversion
Sensing - Intuition
Thinking - Feeling

Myers-Briggs added a fourth criterion:
Judging - Perceiving

The first criterion defines the source and direction of energy expression for a person. The extravert has a source and direction of energy expression mainly in the external world while the introvert has a source of energy mainly in the internal world.

The second criterion defines the method of information perception by a person. Sensing means that a person believes mainly information he receives directly from the external world. Intuition means that a person believes mainly information he receives from the internal or imaginative world.

The third criterion defines how the person processes information. Thinking means that a person makes a decision mainly through logic. Feeling means that, as a rule, he makes a decision based on emotion.

The fourth criterion defines how a person implements the information he has processed. Judging means that a person organizes all his life events and acts strictly according to his plans. Perceiving means that he is inclined to improvise and seek alternatives.

The different combinations of the criteria determine a type. There may be sixteen types. Every type has a name (or formula) according to the combination of criteria. For example:
Introvert Sensing Thinking Judging or
Extravert Intuitive Feeling Perceiving

For a certain person a type formula and quantitative measure of expression of each criterion (strength of the preference) can be determined using the Type inventory. Then the corresponding type description can be represented. So, by activating the Jung Typology Test and answering the inventory questions you will discover your type formula, strength of the preferences and type description. It may help you to identify your general life style and your style in certain fields of activity (business, love, education, communications, conflicts).

​Extraversion and Introversion
When we talk about "extraversion" and "introversion", we are distinguishing between the two worlds in which all of us live. There is a world inside ourselves, and a world outside ourselves. When we are dealing with the world outside of ourself, we are "extraverting". When we are inside our own minds, we are "introverting".

We are extraverting when we:

Talk to other people
Listen to what someone is saying
Cook dinner, or make a cup of coffee
Work on a car

We are introverting when we:

Read a book
Think about what we want to say or do
Are aware of how we feel
Think through a problem so that we understand it

Within the context of personality typing, the important distinction is which world we live in more often. Do we define our life's direction externally or internally? Which world gives us our energy, and which do we perhaps find draining?

Sensing and INtuition

The "SN" preference refers to how we gather information. We all need data on which to base our decisions. We gather data through our five senses. Jung contended that there are two distinct ways of perceiving the data that we gather. The "Sensing" preference absorbs data in a literal, concrete fashion. The "Intuitive" preference generates abstract possibilities from information that is gathered. We all use both Sensing and Intuition in our lives, but to different degrees of effectiveness and with different levels of comfort.

We are Sensing when we:

Taste food
Notice a stoplight has changed
Memorize a speech
Follow steps in a plan

We are Intuitive when we:

Come up with a new way of doing things
Think about future implications for a current action
Perceive underlying meaning in what people say or do
See the big picture

Within the context of personality typing, the important distinction is which method of gathering information do we trust the most? Do we rely on our five senses and want concrete, practical data to work with? Or do we trust our intuitions without necessarily building upon a solid foundation of facts?

Thinking and Feeling

When Jung studied human behavior, he noticed that people have the capability to make decisions based on two very different sets of criteria: Thinking and Feeling. When someone makes a decision that is based on logic and reason, they are operating in Thinking mode. When someone makes a decision that is based on their value system, or what they believe to be right, they are operating in Feeling mode. We all use both modes for making decisions, but we put more trust into one mode or the other. A "Thinker" makes decisions in a rational, logical, impartial manner, based on what they believe to be fair and correct by pre-defined rules of behavior. A "Feeler" makes decisions on the individual case, in a subjective manner based on what they believe to be right within their own value systems.

We are making decisions in the Thinking mode when we:

Research a product via consumer reports, and buy the best one to meet our needs

Do "The Right Thing", whether or not we like it
Choose not to buy a blue shirt which we like, because we have two blue shirts
Establish guidelines to follow for performing tasks

We are making decisions in the Feeling mode when we:

Decide to buy something because we like it
Refrain from telling someone something which we feel may upset them
Decide not to take a job because we don't like the work environment
Decide to move somewhere to be close to someone we care about

Some decisions are made entirely by Thinking or Feelings processes. Most decisions involve some Thinking and some Feeling. Decisions that we find most difficult are those in which we have conflicts between our Thinking and Feeling sides. In these situations, our dominant preference will take over. Decisions which we find easy to make and feel good about are usually a result of being in sync with both our Feeling and Thinking sides.

Judging and Perceiving

Judging and Perceiving preferences, within the context of personality types, refers to our attitude towards the external world, and how we live our lives on a day-to-day basis. People with the Judging preference want things to be neat, orderly and established. The Perceiving preference wants things to be flexible and spontaneous. Judgers want things settled, Perceivers want thing open-ended.

We are using Judging when we:

Make a list of things to do
Schedule things in advance
Form and express judgments
Bring closure to an issue so that we can move on

We are using Perceiving when we:

Postpone decisions to see what other options are available
Act spontaneously
Decide what to do as we do it, rather than forming a plan ahead of time
Do things at the last minute

We all use both Judging and Perceiving as we live our day-to-day life. Within the context of personality type, the important distinction is which way of life do we lean towards, and are more comfortable with.

The differences between Judging and Perceiving are probably the most marked differences of all the four preferences. People with strong Judging preferences might have a hard time accepting people with strong Perceiving preferences, and vice-versa. On the other hand, a "mixed" couple (one Perceiving and one Judging) can complement each other very well, if they have developed themselves enough to be able to accept each other's differences.

The Executive

As an ENTJ, your primary mode of living is focused externally, where you deal with things rationally and logically. Your secondary mode is internal, where you take things in primarily via your intuition.

ENTJs are natural born leaders. They live in a world of possibilities where they see all sorts challenges to be surmounted, and they want to be the ones responsible for surmounting them. They have a drive for leadership, which is well-served by their quickness to grasp complexities, their ability to absorb a large amount of impersonal information, and their quick and decisive judgments. They are "take charge" people.

ENTJs are very career-focused, and fit into the corporate world quite naturally. They are constantly scanning their environment for potential problems which they can turn into solutions. They generally see things from a long-range perspective, and are usually successful at identifying plans to turn problems around - especially problems of a corporate nature. ENTJs are usually successful in the business world, because they are so driven to leadership. They're tireless in their efforts on the job, and driven to visualize where an organization is headed. For these reasons, they are natural corporate leaders.

There is not much room for error in the world of the ENTJ. They dislike to see mistakes repeated, and have no patience with inefficiency. They may become quite harsh when their patience is tried in these respects, because they are not naturally tuned in to people's feelings, and more than likely don't believe that they should tailor their judgments in consideration for people's feelings. ENTJs, like many types, have difficulty seeing things from outside their own perspective. Unlike other types, ENTJs naturally have little patience with people who do not see things the same way as the ENTJ. The ENTJ needs to consciously work on recognizing the value of other people's opinions, as well as the value of being sensitive towards people's feelings. In the absence of this awareness, the ENTJ will be a forceful, intimidating and overbearing individual. This may be a real problem for the ENTJ, who may be deprived of important information and collaboration from others. In their personal world, it can make some ENTJs overbearing as spouses or parents.

The ENTJ has a tremendous amount of personal power and presence which will work for them as a force towards achieving their goals. However, this personal power is also an agent of alienation and self-aggrandizement, which the ENTJ would do well to avoid.

ENTJs are very forceful, decisive individuals. They make decisions quickly, and are quick to verbalize their opinions and decisions to the rest of the world. The ENTJ who has not developed their Intuition will make decisions too hastily, without understanding all of the issues and possible solutions. On the other hand, an ENTJ who has not developed their Thinking side will have difficulty applying logic to their insights, and will often make poor decisions. In that case, they may have brilliant ideas and insight into situations, but they may have little skill at determining how to act upon their understanding, or their actions may be inconsistent. An ENTJ who has developed in a generally less than ideal way may become dictatorial and abrasive - intrusively giving orders and direction without a sound reason for doing so, and without consideration for the people involved.

Although ENTJs are not naturally tuned into other people's feelings, these individuals frequently have very strong sentimental streaks. Often these sentiments are very powerful to the ENTJ, although they will likely hide it from general knowledge, believing the feelings to be a weakness. Because the world of feelings and values is not where the ENTJ naturally functions, they may sometimes make value judgments and hold onto submerged emotions which are ill-founded and inappropriate, and will cause them problems - sometimes rather serious problems.

ENTJs love to interact with people. As Extroverts, they're energized and stimulated primarily externally. There's nothing more enjoyable and satisfying to the ENTJ than having a lively, challenging conversation. They especially respect people who are able to stand up to the ENTJ, and argue persuasively for their point of view. There aren't too many people who will do so, however, because the ENTJ is a very forceful and dynamic presence who has a tremendous amount of self-confidence and excellent verbal communication skills. Even the most confident individuals may experience moments of self-doubt when debating a point with an ENTJ.

ENTJs want their home to be beautiful, well-furnished, and efficiently run. They're likely to place much emphasis on their children being well-educated and structured, to desire a congenial and devoted relationship with their spouse. At home, the ENTJ needs to be in charge as much as he or she does in their career. The ENTJ is likely best paired with someone who has a strong self-image, who is also a Thinking type. Because the ENTJ is primarily focused on their careers, some ENTJs have a problem with being constantly absent from home, physically or mentally.

The ENTJ has many gifts which make it possible for them to have a great deal of personal power, if they don't forget to remain balanced in their lives. The are assertive, innovative, long-range thinkers with an excellent ability to translate theories and possibilities into solid plans of action. They are usually tremendously forceful personalities, and have the tools to accomplish whatever goals they set out for.
