Carl Jung’s theory of psychological types, which later influenced the Myers-Briggs Type Indicator (MBTI) development, introduced the concept of cognitive functions. These cognitive functions are fundamental to understanding how people perceive the world and make decisions. Each MBTI type uniquely combines these functions, influencing an individual’s behavior in various ways. Here’s a breakdown of how these cognitive functions manifest in behavior:
Introverted Intuition (Ni)
- Associated Types: INTJ, INFJ
- Manifestation in Behavior:
- Visionary Thinking: Ni-dominant individuals often think about the future, seeing patterns and possibilities others may miss. They are strategic thinkers, usually planning many steps ahead.
- Focus on Underlying Meaning: These individuals are less concerned with surface details and more interested in what things mean or what they represent.
- Introspection and Reflection: Ni users spend a lot of time reflecting inwardly, which makes them seem reserved or detached from their immediate environment.
Extraverted Intuition (Ne)
- Associated Types: ENTP, ENFP
- Manifestation in Behavior:
- Exploration of Ideas: Ne-dominant individuals are constantly brainstorming and generating ideas. They thrive on novelty and are always looking for new possibilities.
- Seeing Multiple Perspectives: They have a knack for seeing connections between seemingly unrelated things and are often open-minded, considering various perspectives before forming an opinion.
- Adaptability: Ne users are often flexible and adaptable, quickly shifting focus when something new and exciting catches their attention.
Introverted Thinking (Ti)
- Associated Types: INTP, ISTP
- Manifestation in Behavior:
- Logical Analysis: Ti-dominant individuals are highly analytical, often engaging in deep, abstract thinking. They prioritize internal consistency and logical coherence.
- Detachment and Objectivity: They approach situations with a detached, objective mindset, sometimes making them appear aloof or overly critical.
- Complex Problem-Solving: Ti users are often drawn to solving complex problems, enjoying puzzles and theoretical challenges.
Extraverted Thinking (Te)
- Associated Types: ENTJ, ESTJ
- Manifestation in Behavior:
- Efficiency and Organization: Te-dominant individuals focus on getting things done in the most efficient way possible. They are often decisive, direct, and structured in their approach.
- Focus on Results: They prioritize outcomes and are often driven by a desire to achieve tangible results. This can make them excellent leaders and organizers.
- Preference for Clear Systems: Te users prefer clear rules, systems, and structures. They often take charge in organizing projects and tasks, ensuring that everything runs smoothly.
Introverted Feeling (Fi)
- Associated Types: INFP, ISFP
- Manifestation in Behavior:
- Strong Internal Values: Fi-dominant individuals are guided by a deeply personal sense of right and wrong. Their decisions are often based on what feels true to their core values.
- Emotional Depth: They experience emotions intensely and can be very sensitive to their emotional states and those of others.
- Authenticity and Integrity: Fi users prioritize authenticity in themselves and others. They strive to live in alignment with their values and can be very empathetic and compassionate.
Extraverted Feeling (Fe)
- Associated Types: ENFJ, ESFJ
- Manifestation in Behavior:
- Social Harmony: Fe-dominant individuals are highly attuned to the emotions of others. They often strive to create harmony in their environment, valuing consensus and cooperation.
- Empathy and Responsiveness: They are usually warm, caring, and responsive to the needs of others, often taking on the role of caretaker or mediator in social situations.
- Focus on Relationships: Fe users often prioritize relationships and may put others’ needs above their own. They are skilled in navigating social dynamics and building connections.
Introverted Sensing (Si)
- Associated Types: ISTJ, ISFJ
- Manifestation in Behavior:
- Attention to Detail: Si-dominant individuals are often meticulous and detail-oriented. They have a strong memory for past experiences and rely on these memories to inform their decisions.
- Preference for Routine: They often prefer stability, tradition, and routine, finding comfort in familiar environments and established procedures.
- Conservatism and Caution: Si users tend to be cautious and may resist change, preferring to stick with what has been proven to work.
Extraverted Sensing (Se)
- Associated Types: ESTP, ESFP
- Manifestation in Behavior:
- Present-Moment Focus: Se-dominant individuals are highly attuned to their physical surroundings and are often spontaneous and action-oriented.
- Love for Sensory Experiences: They often seek out new and exciting experiences, enjoying the thrill of the moment and the sensory pleasures of life.
- Practicality and Action: Se users are typically pragmatic and hands-on, preferring to deal with life’s concrete and tangible aspects rather than abstract theories.

Understanding Cognitive Function Stacks
Each MBTI type uniquely combines these cognitive functions, typically with four primary functions arranged in a “stack.” The order of these functions (dominant, auxiliary, tertiary, and inferior) significantly affects behavior:
- Dominant Function: The most natural and most vital function. It governs how the individual primarily interacts with the world.
- Auxiliary Function: Supports the dominant function and helps balance the personality.
- Tertiary Function: Develops later in life and provides additional depth to personality but is less natural than the dominant and auxiliary functions.
- Inferior Function: The least developed function is often a source of personal growth and challenge.
