Personality Type Basics and Dynamics

Type Basics

The Myers-Briggs® personality type framework derives from Carl Jung’s work, as refined by Katharine Briggs, Isabel Briggs Myers, and many others. Briggs and Myers developed the Myers-Briggs Type Indicator ® (MBTI®) assessment, a widely administered tool that helps people identify their personality preferences.

There are two basic components of the Myers-Briggs personality type system:

  • The four preference pairs—pairs of opposite type preferences
  • The 16 four-letter types—personality patterns resulting from the interaction of people’s choices on the four preference pairs

The Four Preference Pairs

The fundamental differences between people, in terms of the four basic ways in which they use their mind, are described by the four preference pairs: Extraversion–Introversion (E–I), Sensing–Intuition (S–N), Thinking–Feeling (T–F), and Judging–Perceiving (J–P).

  • e i Directing and Receiving Energy
  • s n Taking In Information
  • t f Deciding and Coming to Conclusions
  • j p Approaching the Outside World
e i

The E–I Preference Pair The way you direct and receive energy

e

Extraversion

People who prefer Extraversion tend to direct their energy toward the outside world and get energized by interacting with people and taking action.

i

Introversion

People who prefer Introversion tend to direct their energy toward their inner world and get energized by reflecting on their ideas and experiences.

s n

The S–N Preference Pair The way you take in information

s

Sensing

People who prefer Sensing tend to take in information that is real and tangible. They focus mainly on what they perceive using the five senses.

n

Intuition

People who prefer Intuition tend to take in information by seeing the big picture. They focus mainly on the patterns and interrelationships they perceive.

t f

The T–F Preference Pair The way you decide and come to conclusions

t

Thinking

People who prefer Thinking typically base their decisions and conclusions on logic, with accuracy and objective truth the primary goals.

f

Feeling

People who prefer Feeling typically base their decisions and conclusions on personal and social values, with understanding and harmony the primary goals.

j p

The J–P Preference Pair The way you approach the outside world

j

Judging

People who prefer Judging typically come to conclusions quickly and want to move on, and take an organized, planned approach to the world.

p

Perceiving

People who prefer Perceiving typically look for more information before coming to conclusions and take a spontaneous, flexible approach to the world.

The 16 Personality Types

The eight preferences when combined in all possible ways form 16 four-letter types.

Type Dynamics

The four letters of your type also contain important hidden information—including information about the four mental processes and clues about your development path.

The Four Mental Processes

The four preferences in the middle two preference pairs (Sensing, Intuition, Thinking, and Feeling) describe the important elements of how a person uses his or her mind. These are referred to as the mental processes. Sensing and Intuition, known as the perceiving processes, describe two opposite ways people tend to take in information. Thinking and Feeling, the judging processes, describe two opposite ways people tend to make decisions and come to conclusions.

Each of these four mental processes takes on a different character depending on whether it is directed toward the outside world (extraverted) or toward one’s inner world (introverted). This refinement of the four processes yields the eight patterns of mental activity.

Jung asserted that everyone uses all eight of these mental patterns, but with differing degrees of awareness and ease. Review the following table to understand what each of these patterns contributes to how you make sense of the world. You may want to take a few minutes to try the suggested activity for experiencing each pattern.

Contributions of the Eight Mental Patterns

Mental Pattern
Contribution
Suggested Activity

SeExtraverted Sensing

arrow

Contribution

What is. The individual . . .

Takes in data via the five senses and trusts them

Notices what is factual and observable in the present

Is keenly aware of specific details in the here and now

Suggested Activity

Get an orange. Describe the orange, in detail, exactly as you experience it right now.

SiIntroverted Sensing

arrow

Contribution

What was. The individual . . .

Takes in and trusts information based on tangiblepast experiences

Links specific data in the here and now to stores of data taken in previously

Trusts experience and values history

Suggested Activity

Hold the orange. Close your eyes and think of the first time you encountered an orange. Recall all the details (sight, smell, sounds, location, who you were with, etc.).

NeExtraverted Intuition

arrow

Contribution

What could be. The individual . . .

Envisions what is by imagining what might be

Sees patterns, associations, and a range of possibilities for the future

Can project the future given today’s data

Suggested Activity

Put the orange in front of you. With someone else, list all the novel uses you can imagine for an orange.

NiIntroverted Intuition

arrow

Contribution

What will be. The individual . . .

Produces and trusts insights into the meaning of a situation

Holds a clear picture of the future that comes from instincts or hunches

Suggested Activity

Close your eyes. Think about what an orange symbolizes, what meaning it holds for you.

TeExtraverted Thinking

Contribution

What is true. The individual . . .

Critically analyzes in pursuit of finding “the best”

Trusts logic, structure, and order to drive quick action

Seeks clear outcomes and efficiency

Suggested Activity

Take five oranges. Organize them based on some objective criteria. See if someone else can identify the criteria you used.

TiIntroverted Thinking

Logically analyzes to clarify underlying frameworks

Is quick to find flaws in logic or faulty assumptions

Seeks precision

Suggested Activity

Research the family, genus, and species of orange trees, noting what distinguishes one species from another.

FeExtraverted Feeling

arrow

Contribution

What is valued. The individual . . .

Feels empathy for and connects easily with others

Wants action to align with stated or implied group values

Feels others’ emotions and trusts this type of data most

Suggested Activity

Describe how oranges can be used to better society or improve the human condition.

FiIntroverted Feeling

Contribution

What resonates. The individual . . .

Acts in accordance with personal core values or mission

Keeps feelings private rather than sharing them widely

Seeks internal alignment, harmony

Values integrity of aligning words with actions

Suggested Activity

Describe what matters most deeply to you. How does an orange reflect that? How are you influenced in daily life by those values?

The Interaction Between Preferences

Your four-letter type describes a dynamic system, not a static picture. The interaction between your preferences plays an important role in how you express your type. For each type, two of the eight patterns described above take precedence over all the others. These are referred to as your favorite process, which Jung called the dominant function, and your second process, which Jung called the auxiliary function.

  • Favorite process. This is the mental process you use most habitually. It is represented by one of the middle two letters of your four-letter type along with a subscript letter, “e” or “i,” showing whether you use it outwardly (e) or inwardly (i).
  • Second process. Your second process complements your favorite process. If your favorite process is one of the perceiving processes (used in taking in information: S or N), your second process is a judging process (used in making decisions: T or F). Again, a subscript letter, “e” or “i,” identifies whether you use it outwardly (e) or inwardly (i).

Combined, your favorite and second processes indicate how you understand your world and make decisions.

The subscript letters “e” and “i” attached to your favorite and second processes also balance each other. If, as indicated by the first letter of your type, you prefer Introversion (I), your favorite process typically operates inwardly and is less visible to others. Your second process balances this by operating outwardly. If you prefer Extraversion (E), your favorite process typically is used outwardly, visible to and engaging the people and things around you, and your second process creates balance by being oriented inwardly.

Your third process, which Jung called the tertiary function, is the preference opposite your second process. For example, if your second process is Sensing (either extraverted or introverted), your third process will be Intuition. Your fourth, or least preferred, process is the preference opposite your favorite process. For example, if your favorite process is Feeling (either extraverted or introverted), your fourth process will be Thinking.

Using your favorite and second processes is usually as easy as writing with your preferred hand and takes no more attention than that. Using your third and fourth processes is more like writing with your other hand. It definitely takes more energy and concentration, can be more tiring, and often turns out a bit shakier in terms of results. But you certainly can use these processes, and you’ve probably done so many times, even in the past few days.
