Myers-Briggs Type Indicator (MBTI)

MBTI Personality Inventory

The Myers-Briggs Type Indicator (MBTI) is a personality assessment tool based on the work of Swiss psychiatrist Carl Jung. It was developed by Katherine Briggs and her daughter Isabel Briggs Myers, who were inspired by Jung’s theory of personality types.

Since the dawn of time, humans have drawn up schematics to describe and categorize our personalities. From the four temperaments of the ancient civilizations to the latest advances in psychology, we have been driven to fit the variables and complexities of human personality into well-defined models. Although we are still some time away from being able to do that, the current models account for our most important personality traits and can predict our behavior with a high degree of accuracy.

Carl Gustav Jung – Theory of Psychological Types

Jung was the founder of analytical psychology. The scholar argued random variations in human behavior were explainable. He claimed these distinctions occurred because people used their perception and judgment differently. Jung said “perception” is how an individual becomes aware of items, people, events, and ideas. He defined “judgment” as the way someone develops conclusions about what they’ve perceived. Most individuals differ in the ways they perceive the world, and how they reach conclusions. Their differences correspond to their interests, reactions, values, motivations, and skills.

Jung’s theory of psychological types is perhaps the most influential creation in personality typology, and it has inspired a number of different theories. One of Jung’s key contributions was the development of the concept of Introversion and Extraversion – he theorized that each of us falls into one of these two categories, either focusing on the internal world (Introvert) or the outside world (Extravert). Besides Introversion and Extraversion, Jung coined the concept of so-called cognitive functions, separated into Judging or Perceiving categories. According to Jung, each person prefers one of these cognitive functions and may most naturally rely on it in everyday situations.

MBTI – Underlying Theory

In the 1920s Katharine Cook Briggs noticed Jung’s theory. She later co-authored a personality indicator still used today, the Myers-Briggs Type Indicator (MBTI). Briggs was a teacher with an avid interest in personality typing, having developed her own type theory before learning of Jung’s writings. Together with her daughter, Isabel Briggs Myers, they developed a convenient way to describe the order of each person’s Jungian preferences – this is how four-letter acronyms were born. The purpose of the MBTI personality inventory is to make the theory of psychological types described by C. G. Jung understandable and useful in people’s lives. 

The MBTI theory suggests that people have innate preferences for certain ways of thinking, feeling, and acting. One can group them into 16 personality types. These types are based on four pairs of opposite preferences:

1. Extraversion (E) vs. Introversion (I): Extraverts are energized by social interaction and external stimulation, while introverts are energized by solitude and internal reflection.
2. Sensing (S) vs. Intuition (N): Sensors rely on their senses and direct experience to process information, while intuitives rely on patterns and abstract concepts to interpret information.
3. Thinking (T) vs. Feeling (F): Thinkers use logical analysis to make decisions, while feelers prioritize personal values and emotions.
4. Judging (J) vs. Perceiving (P): Judgers prefer structure and organization, while perceivers prefer spontaneity and flexibility.

Preference Pair 1: World Views

Individuals see the world in different ways. People who prefer to focus on the outer world them are called extroverts. Introverts focus on their inner thoughts and perceptions.

Extraversion (E): Individuals feel energetic spending time around other people are extroverts. They share several common traits.

• They can understand problems better when they talk out loud or speak to others.
• Extroverts see themselves as outgoing, people persons with a wide-range of friends.
• They feel comfortable working within groups and have a wide range of friends. 
• They jump quickly into activities before thinking them over.

Introversion (I): People who feel energetic dealing with ideas, memories, reactions, or pictures are introverts. Introverts share these behavioral traits.

• Their peers see them as being reserved or reflective. 
• Introverts prefer doing things alone, or with one or two people.
• They like to have a clear picture about what they’re doing before they act.
• Sometimes, they spend too much time reflecting and fail to take action quickly enough.

Preference Pair 2: Gathering Information

The next personality pair examines how people collect information from the environment. People who focus on details are sensors. Individuals that add meaning to the world are intuitive people.

Sensing (S): Sensors people pay attention to physical reality, facts, and data. They are concerned about what they see, touch, taste, smell, or hear. Sensors want to put their experience and education to practical use. They share several common traits.

• These persons work through facts until they understand problems.
• Sensors are pragmatic: they use facts to form the big picture.
• They trust their own experiences rather than symbols or words.
• Sensors miss new possibilities because they pay so much attention to facts.

Intuition (N): Intuitive people pay attention to their impressions, meanings, or patterns rather than hands-on experience. They have several traits.

• These individuals enjoy the new and different.
• They think about future events, symbols, and abstract theories.
• These persons remember impressions more than facts.
• Intuitive people solve problems by examining ideas and possibilities.
• They focus on ideas so intently that they don’t turn them into reality.

Preference Pair 3: Decision Making

People make decisions in different ways. Individuals that prefer consistency and logic are thinkers. Others who examine how their decisions will impact people and their circumstances are feelers.

Thinking (T): Thinkers make decisions using their brains. These people search for truth, regardless of the situation. Thinkers share several unique traits.

• Thinkers are task-oriented: they use logic to make decisions.
• They analyze the pros and cons of situations.
• These individuals prefer to be impersonal and fair. They don’t allow their desires or other opinions to influence them.
• Thinkers like scientific fields where logic is essential.
• These persons search for logical explanations or solutions.
• They notice inconsistencies.

Feeling (F): These individuals appear warm, caring, and tactful. Feelers make better decisions when they consider other people’s viewpoints. They try to establish harmonious relationships.

• These individuals are concerned with values and what’s good for others.
• Feelers are people or communications oriented.
• They are nervous when harmony isn’t present.
• These people search for what’s important to others.
• Feelers make heart-based, compassionate decisions.
• They won’t communicate hard truths to spare other people’s feeling.
• Feelers appear idealistic, indirect, and emotional.

Preference Pair 4: Structuring Meaning

The fourth preference pair describes how people behave in the outer world. It describes behaviors that other people notice.

People who use the Judging (J) function prefer structure and finite decisions. Individuals that use the Perceiving (P) function are flexible, adaptable, and gather new information.

Judging (J): These individuals are decisive and use a decision-based preference (whether Thinking or Feeling) in the outer world. They appear to have a planned, orderly life. They are comfortable after they finalize matters. Judgers are flexible: they stay open to new information.

• These individuals judge, but they aren’t judgmental of other people. The two terms aren’t related.
• Judgers are task-oriented and make lists of things to do.
• They prefer to work before playing to avoid rushing before deadlines.
• Judgers focus so much on goals they can miss new information.

Perceiving (P): Perceivers (whether Sensing or Intuitive) prefer a flexible, spontaneous way of life. These people try to understand the world and adapt to it.

They don’t organize their environments. Instead, they remain open to new information. These individuals appear loose and casual and keep plans to a minimum.

• Perceivers prefer to take in information, but it doesn’t mean they have quick perceptions of people or events.
• These individuals prefer to stay open to respond to events.
• They mix work with play and complete tasks in bursts of energy.
• Approaching deadlines stimulate Perceivers to finish their work.
• These individuals stay open to new information, so they don’t miss out on making important decisions.

The MBTI assessment consists of a series of questions that ask individuals to choose between two opposite preferences. Based on their answers, individuals are assigned a four-letter code representing their personality type, such as ISTJ (Introverted, Sensing, Thinking, Judging) or ENFP (Extraverted, Intuitive, Feeling, Perceiving).

The MBTI has 16 personality combinations. Every personality type brings a unique perspective when they interact with others. These personality insights help employees and supervisors understand one another. Once people learn what motivates other people, they can relate to others who think or act differently.

There are four classes of personality groups in the MBTI: Guardians, Rationals, Artisans, and Idealists:

• Guardians – Supervisors (ESTJ), Inspectors (ISTJ), Providers (ESFJ), Protectors (ISFJ)
• Rationals – Commanders (ENTJ), Masterminds (INTJ), Visionaries (ENTP), Architects (INTP).
• Artisans – Dynamos (ESTP), Craftpersons (ISTP), Performers (ESFP), Composers (ISFP).
• Idealists – Teachers (ENFJ), Counselor (INFJ), Champions (ENFP), Healers (INFP).

The goal of knowing about personality type is to understand and appreciate differences between people. As all types as per Myers-Briggs Type Indicator (MBTI) are equal, there is no best type.

Regardless of its structure, any type-based theory will struggle to describe or characterize people whose scores lie near the dividing line. A different way to look at personalities is through the lens of a trait-based rather than a type-based model. What do we mean by that? Instead of creating an arbitrary number of categories and attempting to fit people within them, a trait-based model simply studies the degree to which people exhibit certain traits.

A trait-based approach makes it easier to reliably measure correlations between personality traits and other characteristics – for example, political attitudes. This is why trait-based approaches dominate psychometric research, but that’s more or less the only area where these approaches are dominant. Because they don’t offer types or categorizations, trait-based theories don’t translate as well as type-based theories into specific recommendations and takeaways.

While the Myers-Briggs Type Indicator theory has been widely used for decades, it is also controversial and has been criticized for its lack of scientific validity and reliability. Some critics argue that the MBTI assessment is too simplistic and that it oversimplifies complex human personalities, while others believe that it can be useful as a tool for self-awareness and personal growth.
