This test offers a classification in 16 Personality And it is often used as a starting point to reflect on oneself, on one’s preferences and potential.
In this article we will explore what is the MBTI testhow reliable it is, as it takes place, what are the 16 types of personality identified and how to interpret the results. Finally, we will see how this tool can fit into a path of personal growth and psychological well -being.
What is personality?
Before going into us in Test of the 16 personalitiesis it useful to take a step back and ask ourselves: what do we mean exactly with “personality”? According to the Definition of the DSM-5 (Diagnostic and statistical manual of mental disorders), the personality traits are:
“The personality traits are constant patterns of perceiving, relating and thinking about the environment and themselves, which are manifested in a broad spectrum of social and personal contexts”.
In simpler words, the personality is thatset of ways of thinking and acting which, despite being influenced by the context and experiences, makes each person peculiar It is unique. It is our characteristic way of being in the world.
THE’Myers Briggs indicator It fits into this field with the aim of mapping these differences. The Meaning of MBTI it is in fact Myers-Briggs Type Indicatorand according to this model the different ways of being can be traced back to Sixteen types main, each with its specific inclinations.
The test roots: Jung’s influence
To fully understand the MBTI testit is important to know its origins. The tool It is based on the theories of Carl Gustav Jungone of the most influential figures of psychology. Jung, in his work, did not aim to label people, but to understand theexistence of different psychological typesthat is, different ways and equally valid to approach life. He identified four psychic functions fundamental that we all use, but with different preferences:
- thought
- feeling
- intuition
- sensation
In his essay Psychological typesJung further deepens this vision:
“All these types they divide into rational and irrational. They belong to the former the type of thought and the sentimental one; to the second the sensory type and the intuitive type. Finally, libido preferences allow you to distinguish Introverts and extroverted. All fundamental types can belong to both classes, according to that introversion or extroversion domains. ”
The original Jungian theory therefore emerged 8 different types of character and personalitywho constituted the foundations on which Katharine Cook Briggs and Isabel Myers Briggs then built their indicator.

The MBTI personality test
The eight dominant functions, with which to trace the different types of personality, are the basis for the development of the Myers Briggs test. The researchers developed theMbti test During the Second World Warwith a double goal:
- scientific: make the theory of Jung’s psychological types more understandable and accessible;
- practical: allow women to replace men at the front, identifying with the test of the 16 personalities what the most suitable work was to each of them.
The analysis of the cognitive functions of the ambient test adds to the Jungian categories an interpretative method of evaluation based on the clarification of the dominant and auxiliary function of each type, adding a further function, the “Shadow function”.
Each person will have a main function that will emerge in their behavior. If, for example, the dominant function will be that of perception (intuition or sensation), the individual will be characterized by a particular apthabal attitude. Conversely, if the function of judgment (thought or feeling) predominates it will be the logic to prevail.
