Carl Jung, a Swiss psychiatrist and psychoanalyst, developed a theory of personality that included eight cognitive functions that he believed influenced the way individuals perceive and process information. According to Jung’s theory, each individual has a dominant function that strongly shapes the personality.
His theory on cognitive functions are closely related to the personality types described in the Myers-Briggs Type Indicator (MBTI). The MBTI is a psychological assessment tool that is based on Jung’s theory of personality and is used to identify an individual’s personality type based on their preferences for certain cognitive functions.

According to the MBTI, each individual has a dominant function, followed by a an auxiliary function, which work together to form their personality. The eight cognitive functions identified by Jung are:
- Introverted Sensing (Si)
- Extraverted Sensing (Se)
- Introverted Intuition (Ni)
- Extraverted Intuition (Ne)
- Introverted Thinking (Ti)
- Extraverted Thinking (Te)
- Introverted Feeling (Fi)
- Extraverted Feeling (Fe)
Here is a brief overview of how the MBTI personality types correspond to Jung’s cognitive functions:
- ISTJ (Introverted, Sensing, Thinking, Judging): Dominant function is Introverted Sensing (Si), auxiliary function is Extraverted Thinking (Te)
- ISFJ (Introverted, Sensing, Feeling, Judging): Dominant function is Introverted Sensing (Si), auxiliary function is Extraverted Feeling (Fe)
- INFJ (Introverted, Intuitive, Feeling, Judging): Dominant function is Introverted Intuition (Ni), auxiliary function is Extraverted Feeling (Fe)
- INTJ (Introverted, Intuitive, Thinking, Judging): Dominant function is Introverted Intuition (Ni), auxiliary function is Extraverted Thinking (Te)
- ISTP (Introverted, Sensing, Thinking, Perceiving): Dominant function is Introverted Thinking (Ti), auxiliary function is Extraverted Sensing (Se)
- ISFP (Introverted, Sensing, Feeling, Perceiving): Dominant function is Introverted Feeling (Fi), auxiliary function is Extraverted Sensing (Se)
- INFP (Introverted, Intuitive, Feeling, Perceiving): Dominant function is Introverted Feeling (Fi), auxiliary function is Extraverted Intuition (Ne)
- INTP (Introverted, Intuitive, Thinking, Perceiving): Dominant function is Introverted Thinking (Ti), auxiliary function is Extraverted Intuition (Ne)
- ESTJ (Extraverted, Sensing, Thinking, Judging): Dominant function is Extraverted Thinking (Te), auxiliary function is Introverted Sensing (Si)
- ESFJ (Extraverted, Sensing, Feeling, Judging): Dominant function is Extraverted Feeling (Fe), auxiliary function is Introverted Sensing (Si)
- ENFJ (Extraverted, Intuitive, Feeling, Judging): Dominant function is Extraverted Feeling (Fe), auxiliary function is Introverted Intuition (Ni)
- ENTJ (Extraverted, Intuitive, Thinking, Judging): Dominant function is Extraverted Thinking (Te), auxiliary function is Introverted Intuition (Ni)
- ESTP (Extraverted, Sensing, Thinking, Perceiving): Dominant function is Extraverted Sensing (Se), auxiliary function is Introverted Thinking (Ti)
- ESFP (Extraverted, Sensing, Feeling, Perceiving): Dominant function is Extraverted Sensing (Se), auxiliary function is Introverted Feeling (Fi)
- ENFP (Extraverted, Intuitive, Feeling, Perceiving): Dominant function is Extraverted Intuition (Ne), auxiliary function is Introverted Feeling (Fi)
- ENTP (Extraverted, Intuitive, Thinking, Perceiving): Dominant function is Extraverted Intuition (Ne), auxiliary function is Introverted Thinking (Ti)
Definitions & Examples of the Functions
- Extraverted Sensing (Se) – This function involves the use of the five senses to gather and process information about the physical world. People who are strong in this function are practical, detail-oriented, and focused on the present.
Example: A person who is strong in sensing might be a skilled craftsman who is able to accurately measure and cut wood using a ruler and saw.
Or a person who is strong in sensing might be a successful farmer who is able to observe and understand the needs of their crops and animals, and use their practical skills to care for them.
- Extraverted Intuition (Ne) – This function involves the ability to process information through pattern recognition and the interpretation of symbolic meaning. People who are strong in this function are imaginative, open-minded, and focused on the future.
Example: A person who is strong in intuition might be a successful entrepreneur who is able to see the potential in a new business idea and take risks to bring it to fruition.
Another example is, a person who is strong in intuition might be a successful writer who is able to generate new ideas and explore multiple possibilities in their writing, and use their imagination to create compelling and engaging stories.
- Extraverted Thinking (Te) is a cognitive function that involves the ability to organize and implement ideas in a practical way. People who are strong in this function are organized, efficient, and action-oriented. They tend to focus outwardly on the practical implementation of their ideas, and they are skilled at getting things done.
Example: A person who is strong in extraverted thinking might be a successful project manager who is able to develop and implement plans to complete projects on time and within budget. They might be adept at organizing tasks and resources, and at communicating effectively with team members to ensure that projects are completed successfully.
- Introverted Feeling (Fi) is a cognitive function that involves the ability to understand and process one’s own emotions, values, and beliefs. People who are strong in this function are self-aware, independent, and true to their own values and beliefs. They tend to focus inwardly on their own emotions and values, and they are skilled at understanding their own feelings and motivations.
Example: A person who is strong in introverted feeling might be a successful poet who is able to express their own emotions and values through their writing. They might be adept at understanding and exploring their own feelings, and at using their writing to express those emotions in a deeply personal and authentic way.
- Introverted Sensing (Si) – This function involves the ability to recall and compare past experiences to inform present actions. People who are strong in this function are reliable, grounded, and detail-oriented.
Example: A person who is strong in introverted sensing might be a successful chef who is able to recall the flavors and textures of various ingredients and use that knowledge to create new dishes.
- Introverted Intuition (Ni) – This function involves the ability to foresee and predict the most likely outcome and scenarios, using the whole brain to unconsciously see the hidden patterns and to see the aha moment.
Example: A person with strong Ni can be a visionary business man who foresees potential shift in the market and invest in the right market and products way ahead of his competitors.
- Introverted Thinking (Ti) – This function involves the ability to analyze and understand complex systems and concepts. People who are strong in this function are independent, analytical, and logical.
Example: A person who is strong in introverted thinking might be a successful scientist who is able to conduct experiments, analyze data, and develop theories to explain natural phenomena.
- Extraverted Feeling (Fe) – This function involves the ability to understand and respond to the emotions of others. People who are strong in this function are outgoing, empathetic, and sensitive to the feelings of others.
Example: A person who is strong in extraverted feeling might be a successful teacher who is able to connect with and understand the emotional needs of their students, and use that understanding to create a positive and supportive learning environment.
