What is the MBTI personality test?
The MBTI personality test is a psychometric instrument that classifies people’s personalities into 16 types, based on four dimensions of psychological preferences. Unlike other instruments that measure behavioral traits, the MBTI assessment seeks to identify how a person perceives the world and how they make decisions.
It is used by organizations of all kinds, from Olympic sports teams to multinational corporations, to improve communication, develop leaders, optimize personnel selection, and strengthen team cohesion. The MBTI for organizations has become a standard tool in HR departments and coaching practices worldwide.
MBTI history and origin: from Jung to today
The MBTI was developed by Katharine Cook Briggs and her daughter Isabel Briggs Myers during World War II. Its original goal was to help women entering the labor market identify the roles best suited to their profile.
Its theoretical basis is the theory of psychological types by Swiss psychiatrist Carl Gustav Jung, published in 1921. Jung proposed that people differ in how they perceive the world and how they make decisions, and that these differences can be organized into recognizable patterns.
Officially published in 1962, it is today administered by The Myers-Briggs Company with a presence in more than 115 countries and translations into more than 30 languages. It is the most widely used psychometric test in the world for personal and organizational development.
How the MBTI assessment works: the four axes
The MBTI assessment measures psychological preferences across four dimensions. In each dimension, a person tends toward one of two poles. The combination of the four preferences generates one of the 16 possible MBTI personality types.
Axis 1
Extraversion (E) vs. Introversion (I)
Where does this person get their energy? Extraverts energize through interaction with the outer world. Introverts energize through their inner world: ideas, reflection, and quiet moments.
Axis 2
Sensing (S) vs. Intuition (N)
How does this person process information? S types focus on concrete data and verifiable facts. N types see patterns, possibilities, and connections between abstract ideas.
Axis 3
Thinking (T) vs. Feeling (F)
How does this person make decisions? T types prioritize logic and objective analysis. F types prioritize values, relationships, and the human impact of decisions.
Axis 4
Judging (J) vs. Perceiving (P)
How does this person relate to the outer world? J types seek structure, planning, and closure. P types prefer flexibility, spontaneity, and keeping options open.

MBTI for organizations: applications in coaching and teams

Individual coaching. As a starting point for exploring the client’s natural preferences, communication style, and decision-making patterns. It helps articulate aspects of personality that the client senses but does not know how to name. See how MindSonar is used in coaching contexts.
MBTI team building. Opens conversations about why different people approach the same problems in different ways. When a team understands that differences are about preference rather than attitude, communication improves notably. Explore team building with psychometric tools.

How to apply the MBTI for team building: a practical guide
To get the most value from the MBTI assessment in an organizational context, these are the steps the most experienced professionals follow.
- Define the objective before applying it. The MBTI is a tool, not an end in itself. Before applying it, define what you want to achieve: improve team communication, identify leadership styles, or facilitate a conversation about cognitive diversity.
- Apply it with a certified professional. MBTI results are most valuable when a trained professional interprets them and facilitates the conversation. Without that support, profiles become labels without action. <
