Have you been around people and heard them describe themselves as INTP, ENFJ, or INTJ and left wondering what those letters meant? These letters are among 16 personality types based on the Myers-Briggs Type Indicator (MBTI). 

The Myers-Briggs Type Indicator (MBTI) is a self-report inventory or evaluation that helps identify a person’s personality type and psychological preferences. Katherine Briggs and her daughter Isabel Myers developed a convenient questionnaire based on Carl Jung’s (the father of analytical psychology) psychological types. This helps one explore and understand their personality and others deeply. 

The MBTI inventory is one of the world’s most used psychological tools that offer in-depth and practical information on personality traits that can help in careers, relationships, and self-identity. 

The Four Personality Designations

The MBTI questions categorize individuals into four personality categories based on how they gather information, their perception of the world, and their decision-making. Every person has a preferred quality in each category. These include:

Extraversion (E) vs. Introversion (I): This dichotomy describes how people interact and respond to the world around them. The terms may be familiar to most people, but in MBTI, they differ from popular usage.

Extraverts like focusing on the world around them. They are vibrant in social interactions and are usually action-oriented. They feel energized after spending time with others. 

Introverts love their inner world and enjoy meaningful social interactions. They are thought-oriented and value their decisions and thoughts. They also feel recharged after spending time on their own.

Sensory (S) vs. Intuitive (N): This scale involves looking at how people gather information from the world around them.

Sensory types are attentive to the information they gather from reality, particularly from their five senses. They are detail and fact–oriented and enjoy a hands-on experience. 

Intuitive individuals pay attention to impressions and patterns. They enjoy looking into the future, thinking about possibilities, and exploring abstract theories.  

Thinking (T) vs. Feeling (F): This scale focuses on people’s decision-making based on the information gathered from intuition or sensing functions. They look into facts and data concerning particular emotions, circumstances, and other people.

Thinking individuals place emphasis on facts and objective data. When decision-making, they tend to be logical, consistent, and impersonal. Feeling folks arrive at a conclusion based on the people and emotions involved. 

Judging (J) vs. Perceiving (P): This final scale focuses on how people act and deal with the outside world. 

Judging individuals prefer firm decisions and structure, while perceiving folks are more open, flexible, and adaptable.
