The Myers-Briggs Type Indicator is a personality test designed to help people understand how they and others perceive and judge the world. It is one of the most widely used and studied psychological tools today. Once a person completes the test, they are categorized as one of 16 types, each named with four letters, such as “ESTJ” or “INFP.” Millions of people have taken the survey to find out which “type” best describes themselves.
Carl Gustav Jung, a 20th-century Swiss psychiatrist, came up with the theory of personality types in the 1920s. Isabel Briggs Myers, a student of political science, and her mother, Katharine Cook Briggs, sought to make Jung’s complex theories more accessible and useful to the public.
In the 1940s, they developed the first Myers-Briggs personality inventories, and began to test and refine them, publishing the first version of the Myers-Briggs Type Indicator in 1962. Today, this assessment has been used as a self-reflection tool and interpersonal guide across many realms, from work and relationships to creative pursuits and more.
Drawing on Jung's work, the Myers-Briggs system proposes that the way in which people’s different worldviews guide their behavior can be systematically identified and described. The approach uses four categories:
- “Favorite world,” or how one focuses their attention (introversion [I] or extroversion [E])
- “Information,” or how one takes in and/or interprets information (sensing [S] or intuition [N])
- “Decisions,” or how one makes decisions (thinking [T] or feeling [F])
- “Structure,” or how one deals with the outside world and external input (judging [J] or perceiving [P])
Many people use psychological tests to gain a new perspective on how they and others perceive and respond to the world. This kind of self-knowledge can help us appreciate our strengths and also identify areas for possible experimentation and growth. And learning how others approach life can help us better understand their preferences and behaviors so we can forge deeper connections.
The Myers-Briggs Foundation shares several resources that explain how to take the assessment. It also states that all types are equal, pointing out that “there is no best type.” Below are 16 quotes that epitomize every Myers-Briggs type.

A man who waits to believe in action before acting is anything you like, but he’s not a man of action. It is as if a tennis player, before returning a ball, stopped to think about his views of the physical and mental advantages of tennis. You must act as you breathe.Georges Clemenceau
