The Myers Briggs Type Indicator (or MBTI for short) is a personality test type that divides everyone into 16 personality types across 4 axis:

  • Introversion (I) – Extroversion (E)
  • Intuition (N) – Sensing (S)
  • Thinking (T) – Feeling (F)
  • Judging (J) – Perceiving (P)

What is MBTI?

Have you ever heard someone describe themselves as an INTJ or an ESTP and wondered what those letters could mean? These people are talking about their Myers-Briggs Type Indicator personality type (MBTI).

The Myers-Briggs Personality Type Indicator is a self-report inventory that helps people figure out their strengths, preferences, and personality type. Isabel Myers and her mother Katherine Briggs made the questionnaire based on their work with Carl Jung’s theory of personality types. The MBTI inventory is one of the most used psychological tools in the world today.

This article talks about how the Myers-Briggs types were made, what the 16 MBTI types are, and how this system for figuring out personality types works.

Where the Myers-Briggs personality tests came from

Myer Briggs’s mother, Katharine Cook Briggs, started studying personality in 1917. She came up with a typology in which she said that there are four types of people: meditative, spontaneous, executive, and social. Isabel Briggs Myers continued her mother’s work on typology and eventually took it over completely.

During World War II, Briggs and Myers made the MBTI. They did this because they thought that knowing about personality preferences would help women who were entering the industrial workforce for the first time figure out what jobs would be best for them.

Myer-Briggs Personality Types (Socionics Theory)

Socionics, in psychology and sociology, is a theory of information processing and personality type, distinguished by its information model of the psyche. The idea of Socionics is that information is intuitively divisible into eight categories, called information aspects, which a person’s psyche processes using eight psychological functions. 

The purpose of Socionics is to provide a means of predicting the character of relations and degree of business compatibility, information sharing and psychological compatibility of people before their joining in one collective group.

Socionics is extraversion (E), sensing (S), thinking (T), judgment (J), introversion (I), intuition (N), feeling (F), perception (P). 

Socionics divides people into 16 different types, called sociotypes which are; ESTJ, ENTJ, ESFJ, ENFJ, ISTJ, ISFJ, INTJ, INFJ, ESTP, ESFP, ENTP, ENFP, ISTP, ISFP, INTP & INFP. A formal conversion is carried out following the Myers–Briggs Type Indicator.
