Glossary

A personality type assessment tool developed by Katharine Briggs and Isabel Myers based on psychologist Carl Jung's theory of psychological types. It classifies people's personalities into 16 types and explains the characteristics and behavioral patterns of each type.

A unique personality pattern created by the combination of four dichotomies (E/I, S/N, T/F, J/P), resulting in 16 distinct types. Each type has its own strengths, weaknesses, behaviors, and communication styles.

The degree to which one prefers either side in each dichotomy. It is not absolute but relative, and can flexibly change depending on the situation.

The theory that forms the basis of MBTI, presented by Carl Jung. It is based on cognitive functions (sensing/intuition) and judging functions (thinking/feeling), and attitudes (extraversion/introversion).

Extraverts gain energy from interactions with people and are more interested in the external world. Introverts gain energy from time alone and focus more on the internal world.

Sensors prefer current facts and concrete information, being practical. Intuitives prefer future possibilities and abstract concepts, being creative.

Thinkers prioritize logical and objective judgments, valuing truth and fairness. Feelers prioritize judgments considering people's emotions and values, valuing harmony.

Judgers prefer planned and systematic approaches, adhering to deadlines. Perceivers prefer flexible and spontaneous approaches, exploring new possibilities.

Eight functions that explain how each MBTI type processes information and makes judgments. They are divided into Sensing (Se/Si), Intuition (Ne/Ni), Thinking (Te/Ti), and Feeling (Fe/Fi).

The most developed and frequently used cognitive function in each type. It forms the core of personality and is used most naturally.

The second most developed cognitive function that supports the dominant function. It balances with the dominant function to complete the personality.

The least developed cognitive function, which may appear under stress. It has potential for growth.

A function that focuses on sensory experiences of the present moment and physical reality. It has spontaneous and adventurous tendencies.

A function that compares past experiences and memories, valuing stability and tradition. It emphasizes details and consistency.

A function that explores possibilities and connections, creating new ideas. It has flexible and innovative thinking.

A function that predicts future patterns and meanings, exercising insight. It has strategic and visionary qualities.

A function that establishes logical systems and pursues efficiency. It excels at organization and planning.

A function that builds internal logical systems and pursues accuracy. It engages in analytical and systematic thinking.

A function that considers others' emotions and pursues harmony. It has strong empathy and values social relationships.

A function that makes judgments based on personal values and beliefs. It values authenticity and personal values.

The opposite functions that are not commonly used, which may appear under stress. They represent unconsciously repressed aspects.

A concept explaining how the four cognitive functions (dominant, auxiliary, tertiary, inferior) interact within each type.

A negative state that occurs when only the dominant and inferior functions are repeatedly used under stress. Balanced thinking becomes difficult.

A phenomenon where the inferior function suddenly appears under extreme stress. It may show different behavioral patterns than usual.

A stress reaction where the inferior function suddenly appears, causing behaviors different from the normal personality.

A cognitive error that occurs when trying to fit new information into existing frameworks. It can lead to biases and stereotypes.

An error of reaching conclusions hastily without gathering enough information. It can result in impulsive decisions and biased judgments.

A type with independent and strategic thinking. They excel at long-term planning and efficiency pursuit, and are excellent at solving complex problems.

A passionate and creative personality that explores new ideas and enjoys communicating with people. They are idealistic and inspiring leaders.

A type with exceptional empathy and idealism. They have a strong belief in helping others and making the world a better place.

Charismatic and inspiring leaders. They help others grow, pursue harmony, and have excellent communication skills.

Developed in the 1940s by Isabel Briggs Myers and Katharine Cook Briggs based on Carl Jung's theory of psychological types from the 1920s. It was commercialized in 1962 and is now widely used worldwide.

MBTI test results have reliability showing consistency over time. However, there is ongoing discussion about its scientific validity.

MBTI types are not fixed and can develop with growth and environmental changes. Developing the inferior function is particularly important.

It is important to recognize the unique strengths of each type and effectively apply them in daily life and career.

Effective communication between different types requires understanding and adapting to each other's preferences.
