Understanding personality type with MBTI test

In the corporate environment, the MBTI personality test is a helpful tool for employers to evaluate and select suitable candidates for a particular position in the company. Meanwhile, candidates can also refer to MBTI to determine the career best suits their interests and personality. Besides recruitment and human resource assessment activities of enterprises, MBTI is also applied in other fields such as education, skills training,...

In short, the MBTI test helps individuals to become aware of the world around them and assists in making decisions about all aspects of life.

If you still don't know why so many people use the MBTI, find out in the following article the origin and criteria for personality classification, as well as an overview of the 16 personality groups in the MBTI system.

What Is The MBTI Test?

MBTI stands for Myers-Briggs Type Indicator, a personality classification method developed by two scientists Katherine Briggs and her daughter - Isabel Myers. This method uses multiple-choice questionnaires to determine the strengths and weaknesses of each individual's personality.

Based on the combined answers to the questionnaire, each person will be classified into a personality type in the 16 personality types defined by Briggs and Myers. The goal is to allow test takers to discover more distinctive features of their personality, including interests, thoughts, feelings, and what kind of person they are in different relationships.

Personality Type Indicators in MBTI

The MBTI identifies personality traits to help you better understand yourself, not to make comparisons as to which personality is "better" or "best". In this way, Briggs and Myers believe that MBTI can help people discover the good and bad about themselves, understand those around them, and lead healthier, more positive life.

MBTI Test's Science-Based Theory

It is often known that although Briggs and Myers are the founders and developers of the MBTI, Carl Gustav Jung, the Swedish psychologist, is the father of this method.

According to Jung's taxonomy, people have two main personality types: Introvert - Extrovert, always existing inside each person. But these two factors will prevail differently in each individual, determining that person's personality, actions, and perception towards more internal awareness or more external environment.

In addition, this psychologist also thinks that an individual with Introvert or Extrovert tendencies can be classified according to 4 more characteristics, namely: Thinking - Feeling (Feeling), Sense (Sensation) ) - Intuition (iNtuition). A person with an introvert or an extrovert personality group will have one of the four cognitive functions above.

Then, building on the foundations of Carl Jung's research, Briggs and her daughter Myers added a fourth element: Judging, a way of influencing the outside world. They also tried to make his theory more accessible and understandable to the public.

Thus, there are four criteria to classify human personality; based on the above dichotomies, the MBTI system of 16 personality groups was born. The name of each group has four abbreviations representing four classification criteria.

However, Jung's or Myers-Briggs' theories are based entirely on subjective observations and personal experiences with those around them. Therefore, most psychologists believe that the MBTI has many shortcomings and limitations because "there is no objective evidence" and not any scientific research to prove the hypotheses and speculation above.

So does the MBTI test guarantee accuracy in assessing personality, and is it a valid metric? How reliable is this test? Let's discover the answer in the next section!

MBTI Test's Accuracy

The MBTI test is viral and widely used in commercials and entertainment. But besides that, many people are indifferent and do not know about this test. Some people even expressed doubts about the trial's results and distrust of its accuracy.

Human personality will change over time and environment, so the results of MBTI may not be the same if we do it again after a long time. But if a person executes the test simultaneously or the time between tests is not too long, the results cannot be changed.

However, in one study, about 50% of people who took the MBTI test twice just five weeks apart received utterly different results, which reduced the reliability of the test. However, this assessment method has been repeatedly supplemented and improved by the exclusive research and publishing organization of the MBTI test (with the accuracy and correlation of the published test up to 90%).

In addition, personality is a factor that cannot be explicitly measured, so MBTI is also not a tool that can determine personality and clearly distinguish an individual accurately from a personality with them in reality. The results of the MBTI are, after all, only a reference, not a predictor of the future or the likelihood of success of a particular type of person in specific professions.

The Difference Between the MBTI Test and Other Personality Classification Tools

Here are some personality tests in business that many companies worldwide apply:


The Enneagram is a classification represented by the points of a pie chart, showing the relationship between nine different personality types: Perfectionism, Kindness, Ambition, Personality, Reason, Loyalty, Enthusiastic, Challenging, and Moderate.

Despite having the same level of complexity as the MBTI, the Enneagram tool with its “Basic Fear” and “Basic Desire” approaches is much easier to design than the MBTI test. Therefore, the validity and reliability of Enneagram are relatively better than MBTI.

Big Five

The Big Five test identifies the five most essential aspects of our personality: Openness, Devotion, Extroversion, Pleasure, and Sensitivity.

Unlike the MBTI, this model does not label an individual's personality type into any group but instead checks to see what percentage or score an individual has on each of the five dimensions listed above.

The Big Five model is widely used in research because it does not classify people's personalities. But instead, it marks five aspects of their inherent personality in a continuum, including the child personality element. 

In addition, because it is recognized and perfected by many psychologists, the Big Five test is much more accurate and reliable than the MBTI.

Personality classification tools


Based on research by psychologist William Moulton Marston, DISC is a professional assessment method that helps determine a particular individual's personality by observing that person's behavior at a specific time. Individuals and organizations around the globe use both the MBTI and DISC tools, providing comprehensive insights into human behavior and personality.

However, compared to MBTI, the DISC test is shorter with the number of questions usually in the range of 24-30. Meanwhile, the MBTI questionnaire has many versions, averaging 90 to 200 questions.

DISC uses mainly four behavioral patterns, corresponding to the four abbreviations of the test name: Dominance - Influence - Steadiness - Conscientiousness. While the MBTI assumes that personality is fixed, the DISC extends to different behavioral traits in different situations within the same individual.

4 Personality Classification Criteria in MBTI 

MBTI analyzes and assesses personality based on four classification criteria corresponding to four pairs of categories around our worldview, including:

  • Natural Tendencies: Introversion/Extroversion (I/E)
  • Perception of the world: Sensing/Intuition (S/N)
  • Decisions and Choices: Thinking/Feeling (T/F)
  • How to act: Judging/Perceiving (J/P)

When combined, each element of the above four groups will form 16 personality groups, representing the 16 MBTI types of people.
