Learn the essentials of the Jung Cognitive Functions test

What defines a personality type?

A personality type, according to the work of psychiatrist Carl Jung (who introduced cognitive functions) and Myers and Briggs (who distinguished 16 personality types using those Jungian cognitive functions), is a unique arrangement of several cognitive functions—Sensing, Intuition, Thinking, Feeling—each of which can be expressed in two ways: introverted or extraverted.

What are the 8 Jung cognitive functions?

The 8 Jung cognitive functions are:

  • Si (Introverted Sensing):

    Compares present experiences with past memories and familiar impressions. It values accumulated knowledge, details, and consistency, using previous experiences to understand current situations. Dominant function of: ISFJs and ISTJs.

  • Se (Extraverted Sensing):

    Focuses on the immediate physical environment and experiences the world through the five senses. It responds quickly to changes and opportunities, prioritizing direct action and living in the present moment. Dominant function of: ESFPs and ESTPs.

  • Ni (Introverted Intuition):

    Focuses on uncovering deeper meanings, patterns, and future implications. It relies on unconscious insights and sudden realizations to anticipate what is likely to happen. Dominant function of: INTJs and INFJs.

  • Ne (Extraverted Intuition):

    Explores new possibilities, connections, and interpretations in the external world. It identifies hidden patterns and potential opportunities, focusing on what could be rather than what currently is. Dominant function of: ENFPs and ENTPs.

  • Ti (Introverted Thinking):

    Seeks internal logical consistency by analyzing ideas, concepts, and underlying principles. It develops precise mental frameworks, questions assumptions, and identifies inconsistencies to understand how things work. Dominant function of: ISTPs and INTPs.

  • Te (Extraverted Thinking):

    Focuses on organizing the external world through logic, structure, and efficiency. It establishes plans, rules, and measurable goals, evaluating decisions based on practical results and effectiveness. Dominant function of: ESTJs and ENTJs.

  • Fi (Introverted Feeling):

    Evaluates situations according to deeply held personal values and beliefs. It prioritizes authenticity and inner harmony, determining what feels meaningful, morally right, or worth defending. Dominant function of: INFPs and ISFPs.

  • Fe (Extraverted Feeling):

    Focuses on maintaining harmony and understanding the emotional needs of others. It considers shared values, social expectations, and group dynamics to encourage cooperation and positive relationships. Dominant function of: ENFJs and ESFJs.

What is a dominant, auxiliary, tertiary or inferior function?

In the 16-type model based on Jung’s work, each personality type is described by four cognitive functions, selected from eight possible functions. These functions have different roles and develop at different stages of life, influencing how a person perceives information and makes decisions.

  • Dominant function:

    The most natural and developed function, shaping how a person primarily perceives or judges the world. It develops first, during childhood, and plays the central role in personality.

  • Auxiliary function:

    Supports and balances the dominant function by providing a complementary way of processing information. It develops early in life and has the opposite orientation (introverted or extraverted) to the dominant function.

  • Tertiary function:

    A less developed function that typically becomes more accessible in early adulthood. It is the opposite of the auxiliary function and offers an alternative perspective, though it is generally less consciously controlled.

  • Inferior function:

    The least developed and most challenging function, opposite to the dominant function. It can cause difficulties, particularly under stress, but also represents an important opportunity for personal growth.

Can you have more than one personality type?

We all possess all of Jung’s cognitive functions; we just use them to different degrees. Each personality type reflects a unique way those functions interact. Our personality type is the one we rely on most often or most naturally. Yet in other situations, we may resemble other types, expressing different configurations of cognitive functions.

  • The MBTI® Assessment was developed by Isabel Briggs Myers and Katharine Briggs, while the Jung Cognitive Functions Test was developed by the independent owners of jung-personality.com.
  • The MBTI® Assessment is a paid assessment, while the Jung Cognitive Functions Test is completely free.
  • The MBTI® Assessment measures 4 personality preferences, while the Jung Cognitive Functions Test measures 8 cognitive functions and 4 dichotomous preferences.
