You\u2019ve just come out of a team workshop, and you\u2019ve been given four letters that are supposed to describe you: ESFJ, INTP, or some other combination. Your coworkers are comparing their results; some see themselves in them, while others just shrug. One simple question remains: What do these letters really mean, and how can you apply them at work?<\/p>\n

The MBTI\u00ae (Myers-Briggs Type Indicator) is undoubtedly the most widely used self-awareness tool in the professional world. It\u2019s commonly encountered in management training programs, team-building workshops, and career counseling sessions. Yet it is also one of the most misunderstood: sometimes hyped as a crystal ball that reveals your \u00abtrue self,\u00bb other times dismissed as nothing more than a magazine quiz. The reality is more nuanced, and it is this nuance that makes it useful: where it comes from, how it is constructed, what purpose it serves within an organization, and, above all, what its limitations are.<\/p>\n

A simple definition to start with<\/h2>\n

The MBTI\u00ae is a personality questionnaire that describes preferences<\/strong> : the way a person spontaneously prefers to perceive the world and make decisions. The word is important. We\u2019re not talking about abilities, intelligence, or the quality of one\u2019s work, but about natural tendencies.<\/p>\n

This is the \u00abdominant hand\u00bb metaphor that practitioners often use. You know how to write with both hands, but one requires no effort at all, while the other demands a great deal of concentration. The MBTI\u00ae seeks to identify, across four major dimensions of human functioning, which is your mental \u201cdominant hand.\u201d.<\/p>\n

Based on this logic, sixteen profiles emerge, each formed by a combination of four letters. Each profile isn\u2019t a box that confines you, but rather a description of tendencies\u2014a starting point for better understanding yourself and others: a story of preferences, not a fixed truth about who you are or what you\u2019re capable of.<\/p>\n

The Origins: From Jung to Myers and Briggs<\/h2>\n

To understand the essence of the MBTI\u00ae, we must go back to its theoretical source, the Swiss psychiatrist Carl Gustav Jung<\/strong>. In his book Psychological Types<\/em> (1921), Jung observes that human beings do not process information in the same way: some direct their energy toward the external world, others toward their inner world; some rely on what they perceive through their senses, others on what they sense intuitively. He thus describes \u00abpsychological functions\u00bb that manifest themselves to a greater or lesser degree depending on the individual.<\/p>\n

These ideas will be put into practice by two American women, Katharine Cook Briggs<\/strong> and his daughter Isabel Briggs Myers<\/strong>. During and after World War II, at a time when many people were changing careers, they sought to develop a practical tool that would help everyone find a job suited to their personality. The first formalized questionnaire was developed in the 1940s.<\/p>\n

It\u2019s helpful to keep this history in mind. It grounds the MBTI\u00ae in a benevolent purpose\u2014to help people understand themselves better, not to categorize them\u2014and serves as a reminder that it is based on a long-standing theory developed through introspection rather than contemporary statistical methods. Hence the need for careful use.<\/p>\n

The Four Dimensions of the MBTI\u00ae<\/h2>\n

The core of the tool consists of four axes. On each axis, you fall on one side or the other, and the combination of the four letters defines your type. Here are these dimensions, translated into concrete work situations.<\/p>\n

Energy Orientation: Extraversion (E) or Introversion (I)<\/h3>\n

This dimension describes where you draw your energy from. Be careful not to misunderstand it\u2014it has nothing to do with shyness or social ease.<\/p>\n

A preference for the\u2019Extraversion (E)<\/strong> often manifests as a need to think out loud, to recharge through interaction with others, and to make progress through discussion; thinking alone in front of a screen can quickly become a burden. Conversely, the\u2019Introversion (I)<\/strong> recharges in quiet moments: we like to let an idea mature before sharing it, and a day filled with back-to-back meetings\u2014even a successful one\u2014leaves us exhausted. Two competent colleagues can therefore have very different work styles without one being \u00abbetter\u00bb than the other.<\/p>\n

Information Gathering: Sensing (S) or Intuition (N)<\/h3>\n

The question here is: What do you rely on first to understand a situation?<\/p>\n

Preference Sensation (S)<\/strong> focuses on concrete facts, details, proven experience, and \u00abwhat already works\u00bb; when faced with a project, this person will ask for specific examples and tangible data. The preference Intuition (N)<\/strong> first focuses on connections, possibilities, the big picture, and the \u00abwhat if we did it differently\u00bb approach: she sees the forest before the trees. In meetings, the S profile may find the N profile a bit vague, and vice versa. Aware of their differences, they complement each other remarkably well.<\/p>\n

Decision-Making: Thinking (T) or Feeling (F)<\/h3>\n

This dimension describes the criterion you prioritize when making a decision. Neither is more rational or more intuitive than the other: they represent two decision-making approaches, both of which are valid.<\/p>\n

Preference Thought (T)<\/strong>, from English Thinking<\/em>, is based first and foremost on objective criteria: consistency, logic, and fairness of reasoning. The preference Sentiment (F)<\/strong>, from English Feeling<\/em>, makes decisions while taking the human impact into account: values, harmony, and the decision\u2019s effect on people. When faced with the same budget trade-off, the T profile will focus primarily on the numbers; the F profile will be concerned about the effect on the teams. A sound decision often requires both perspectives.<\/p>\n

Lifestyle: Judging (J) or Perceiving (P)<\/h3>\n

This last dimension describes your relationship with the organization and with time.<\/p>\n

Preference Judgment (J)<\/strong> likes to make decisions, plan, and wrap things up: finishing a project ahead of schedule is satisfying, while last-minute surprises are irritating. The preference Perception (P)<\/strong> likes to keep options open, adapt, and explore: a framework that\u2019s too rigid is stifling, and last-minute flexibility is stimulating rather than stressful. On the same project, the J profile will want a fixed reverse schedule, while the P profile will prefer to make adjustments along the way\u2014a valuable complementarity when it is understood rather than imposed.<\/p>\n

The 16 Types, at a Glance<\/h2>\n

By combining one letter from each dimension, we get sixteen possible types, ranging from ISTJ to ENFP. Rather than providing an exhaustive description\u2014which is best done with the help of a professional\u2014the sixteen profiles are often grouped into four families based on the two central letters (the way information is gathered and decisions are made).<\/p>\n
