Human beings have different ways of thinking and behaving that differentiate us from one another. People have always been tempted to create personality types or models that fit others and ourselves so that we can understand each other better.
Hiring potential collaborators for an organization means putting the person to the test to assess their ability to perform the tasks that will be assigned to them; therefore, it is important and necessary to understand what type of individual we are dealing with and whom we are about to place in a position within our company.
Modern psychology has understood this need and has developed the so-called personality tests. The MBTI personality test is one of these variants and has become very popular in a variety of contexts, including business (personnel selection).
The purpose of the MBTI test is to increase the self-confidence of the person who completes the questionnaire and to offer them possible guidance, for example, on their career choice or compatibility with others. Therefore, the test is also used for career guidance, helping to identify the contributions each candidate can make and whether they really fit the motivational or aptitude requirements of a specific position.
How was the MBTI test born?
The origin of the MBTI personality test dates back to the beginning of the 20th century. The psychologist Carl Gustav Jung, the precursor of analytical psychology, established the concepts of introversion and extroversion as fundamental aspects of personality.
People who tend to be introverted are mainly interested in their inner world. On the other hand, more extroverted people look outward. Jung, for his part, established and identified four basic cognitive functions in human beings: thinking, feeling, intuition and sensation. By combining these four aspects, he described eight personality types.
Based on these ideas presented by Jung, various people dedicated to psychology and research sought to give depth to them. Therefore, in 1962, Katharine Cook Briggs and Isabel Briggs Myers published a study in which they referred to the MBTI, a tool used to analyze and define 16 personality types present in people.
How to take the 16 personalities test or MBTI?
The MBTI test is completed by answering a questionnaire that usually contains 60 to 90 questions. Each question has two possible answers. Depending on the answers given, people can identify one of the 16 personality types. There are no wrong answers here, and no personality is better or worse than another; they simply categorize and provide characteristics unique to each person.
The questionnaire itself consists of questions arranged according to four different scales:
Extraversion (E) – Introversion (I). Extroverted people tend to be more action-oriented; social interaction is very frequent and they enjoy it; they also feel full of vitality when spending time with others. On the other hand, introverts are thought-oriented people, seek deep and truly meaningful interactions, and like to spend time alone. We all exhibit some degree of extroversion and introversion, but most of us tend to prefer one or the other.
Sensing (S) – Intuition (N). Individuals who have a preference for sensing tend to pay special attention to what they perceive and understand through their senses; they also enjoy gaining experience through practice. Intuitive people, on the other hand, are more aware of things; they like to think about the future and imagine it in order to address different possibilities.
Thinking (T) – Feeling (F). This aspect assesses people's decision-making. Individuals focused on thinking give more importance to objective facts and figures, and tend to be consistent, logical and objective when weighing decisions. On the other hand, those who enjoy feelings are more considerate of their own and others' sensitivities and feelings.
Judging (J) – Perceiving (P). People who tend to judge prefer structure and firm decisions. Perceiving people are more flexible, adaptable and open.
