Descriptions of the 8 Letters

Each personality type consists of 4 different letters. This makes up 16 different personality types. Here are descriptions of what each letter represents. Everyone is unique and will have some traits of all 8 letters, but will often be more inclined towards one letter in each pair.

(E) Extrovert vs. (I) Introvert

How we gain our energy.

The main difference between extroverts and introverts is that introverts gain their energy by being alone and extroverts gain their energy by being with others. One is not better than the other, and extroverts are not always loud and introverts are not always quiet. Introverts often enjoy social gatherings, but will get drained faster while involved in these settings. Extroverts also tend to want to be around people more but they still feel they need time alone sometimes.

Reflects before making decisionsTends to make decisions quickly

(S) Sensing vs. (N) Intuitive

How we take in information.

The main difference between sensing and intuition is that sensors take in information via their five senses and through facts, and intuitives take in information via patterns, impressions ands possibilities. 

Process information through the five sensesProcess information through patterns
Thinks in the here and now Thinks of future possibilities
Concrete thinkersAbstract thinkers
Notices detailsSees big picture
Practical Idealistic
Gather info from what they can seeGathers info from underlying patterns

(T) Thinking vs. (F) Feeling

How we make decisions.

The main difference between thinking and feeling is that thinkers make decisions based on facts, and feelers make decisions based on values. In other words, thinkers use their heads more than their hearts and feelers use their hearts more than their heads. But there is a stereotype that needs to be discontinued- Thinkers aren't sensitive to others and feelers never think logically, and women are feelers and men are thinkers. These comparisons below are generalized, everyone will have traits of both in different situations. It really depends what you are more inclined to while making decisions.

Decides with headDecides with heart
Judge based on logicJudge based on feelings
Driven by thoughtDriven by emotion
Gives priority to truthGives priority to relationships
Not easily upset by others' remarksTakes remarks personally

(J) Judging vs. (P) Perceiving

Our lifestyle preference.

The main difference between perceivers and judgers is that judgers prefer their world to be structured and planned, while perceivers prefer their world to be open ended and find that having plans is stifling. Judgers feel a sense of control in planning early and perceivers find a sense of control in leaving their options open.

Like to finish one job before starting anotherStart many things without finishing
Prefer to move towards closureKeeps options open
Prefers to plan before taking actionSpontaneous with actions
Tends to stick to a planTends to change decisions midway
ResponsibleTends to procrastinate


  1. I really appreciate the break down of each letter in practical form

  4. This was really helpful, breaking it down in a language that is not technical makes it very easy, thank you.

  7. Overall, this is a good, short synopsis. (Though you seem to focus on the negative elements of being a P rather than the positive contributions they bring.) Thank you!

    1. Should read "very good, short synopsis". --because it is.

    2. Abba made a good point re the J-P scale. In the MBTI many questions focus on whether you have preferences for J, and if you do not, then your preference is for P. While those with preferences for P may quickly adapt to change, those with J may be less flexible.

  8. MBTI: The Eight Function-Attitudes

    Each of the eight functions can be expressed in either the inner world or the outer world. Sometimes the same function looks very different in one world than in the other. Here are some descriptions of the functions in each world.

    Extraverted Sensing: Acts on concrete data from here and now. Trusts the present, then lets it go.

    Introverted Sensing: Compares present facts and experiences to past experience. Trusts the past. Stores sensory data for future use.

    Extraverted Intuition: Sees possibilities in the external world. Trusts flashes from the unconscious, which can then be shared with others.

    Introverted Intuition: Looks at consistency of ideas and thoughts with an internal framework. Trusts flashes from the unconscious, which may be hard for others to understand.

    Extraverted Thinking: Seeks logic and consistency in the outside world. Concern for external laws and rules.

    Introverted Thinking: Seeks internal consistency and logic of ideas. Trusts his or her internal framework, which may be difficult to explain to others.

    Extraverted Feeling: Seeks harmony with and between people in the outside world. Interpersonal and cultural values are important.

    Introverted Feeling: Seeks harmony of action and thoughts with personal values. May not always articulate those values.
