Hello! Have you ever heard of the term “MBTI”?
MBTI stands for “Myers-Briggs Type Indicator,” and it’s a psychological assessment tool for understanding your personality.
Actually, MBTI has both supporters and critics.
For example, there are criticisms that classifying personalities into 16 types is unreasonable.
However, this doesn’t mean that MBTI is completely useless.
It can be effectively utilized as one tool for understanding your personality.
So, in this article, we’ll provide a detailed explanation of MBTI.
We’ll explain the characteristics and mechanisms of MBTI, its advantages and disadvantages, and how to use it appropriately in an easy-to-understand way, so please read to the end!
Once again, personality researcher and author of Villain Encyclopedia, Tokiwa (@etokiwa999), will provide the explanation.
※We have developed the HEXACO-JP Personality Assessment! It has more scientific basis than MBTI. Tap below for details.

※As mentioned later in the article, the famous 16personalities (16 Type Personality Test) is based on MBTI and Big Five, making it different from MBTI and Big Five. This is explained below.

What is MBTI
Basic Concepts of MBTI
It’s a method that classifies human personality into 16 types.
This diagnostic method helps understand people’s ways of thinking and behavior patterns.
The purpose of MBTI is to deepen self-understanding and understanding of others.
This diagnostic method judges personality based on the following four axes:
- Extraversion and Introversion
- Sensing and Intuition
- Thinking and Feeling
- Judging and Perceiving
The combination of these creates 16 personality types. MBTI shows each person’s strengths and weaknesses.
It also helps improve communication. It can be applied to human relationships in workplaces and schools.
By knowing your personality type, you can see the direction for growth. Understanding others’ types makes it easier to build cooperative relationships.
History and Developers of MBTI
MBTI was created in the United States in the 1940s.
The developers were mother and daughter Katharine Briggs and Isabel Myers.
They focused on the theories of psychologist Carl Jung. Jung’s “Psychological Types” became the foundation of MBTI.
Briggs and Myers thought about putting this theory into practical use.
Their goal was to find ways to utilize people’s individuality. During World War II, the development of this diagnostic method began.
The initial purpose was to assess women’s aptitudes. During wartime, many women began working in new workplaces.
In 1956, it was republished as the “Myers-Briggs Type Indicator.”
Since then, it has become widely used around the world. It’s utilized in business settings and educational environments.
Research by psychology experts continues.
Currently, improvements in MBTI accuracy and expansion of its application range continue to progress.
In other words, MBTI is a diagnostic method supported by long history and extensive research.
The Four Indicators of MBTI
Extraversion (E) and Introversion (I)
Extraversion and Introversion indicate the direction of energy.
First, extraverted people gain energy from the outside world.
On the other hand, introverted people recharge through internal activities.
The characteristics of extraversion are as follows:
- Social and enjoys talking with people
- Active and enjoys going out
- Seeks new experiences and stimulation
The characteristics of introversion are:
- Values alone time
- Prefers deep thinking and introspection
- Prefers small group interactions
However, this is not simply a distinction between being “social” or “shy.”
Rather, it’s a difference in where one gains energy.
Extraverted types refresh themselves by talking with people.
Introverted types become energized by facing themselves in quiet environments.
Sensing (S) and Intuition (N)
Sensing and Intuition represent differences in how information is gathered.
First, sensing types value concrete information obtained through the five senses.
On the other hand, intuitive types focus on overall impressions and possibilities.
The characteristics of sensing types are as follows:
- Think in realistic and practical ways
- Pay attention to details

The characteristics of intuitive types are as follows:

Thinking and Feeling show differences in decision-making methods.
First, thinking types make judgments based on logical analysis.
On the other hand, feeling types value personal values and human relationships.
The characteristics of thinking types are as follows:
- Value objective data
- Value fairness
- Emphasize efficiency and results
The characteristics of feeling types are as follows:
- Sensitive to people’s feelings
- Value harmony
- Make judgments based on personal values
Thinking types analyze problems logically.
Feeling types consider the impact that problems have on people.
Thinking types pursue “what is right.”
Feeling types value “what is good.”
Both approaches have their respective advantages.
Judging (J) and Perceiving (P)
Judging and Perceiving represent ways of dealing with the external world.
First, judging types prefer to make plans and proceed with things in an organized manner.
On the other hand, perceiving types are skilled at adapting flexibly to situations.
The characteristics of judging types are as follows:
- Make plans in advance
- Value meeting deadlines
- Make decisions quickly
The characteristics of perceiving types are as follows:
- Respond with flexibility and adaptability
- Continue to explore new information and options

Academic Evaluation of MBTI
Reliability and Validity of MBTI

While this personality assessment method has both supporters and critics, critics are relatively more numerous.
Various studies have been conducted on its reliability and validity.
The main points of discussion regarding MBTI reliability are as follows:
- Test reproducibility
- Consistency of results
- Stability of measurement
Regarding validity, the following points are discussed:
- Scientific nature of theoretical foundation
- Predictive power in real life
- Relationship with other personality theories
- There are both papers stating no correlation and papers stating correlation with the Big Five (a scientifically trusted personality assessment) that will be introduced later.
Many researchers question the reliability of MBTI. When the same person takes it at different times, the results may change.
There are also criticisms that the boundaries of type classification are ambiguous. It is considered insufficient as a scientific personality assessment method.
Criticisms and Challenges of MBTI
MBTI has several important criticisms and challenges.
Questions have been raised about the scientific basis of this personality assessment method.
Many of the criticisms are directed at the theoretical foundation and implementation methods.
The main criticisms of MBTI are as follows:
- Problems with binary classification
- Lack of statistical support
- Possibility of cultural bias
The following challenges are also pointed out:
- Insufficient consideration of individual change and growth
- Excessive dependence in the workplace

In other words, MBTI is a tool that should be handled carefully.
How to Use MBTI
Using MBTI in Romance
MBTI may be helpful in understanding romantic relationships.
Knowing your partner’s personality type can improve communication.
However, it’s dangerous to judge compatibility based on MBTI alone.
The key points for using MBTI in romance are as follows:
- Deepening self-understanding
- Understanding your partner’s characteristics
- Adjusting communication styles
Specifically, the following applications can be considered:
- Predicting your partner’s preferences and values
- Avoiding potential conflicts
- Understanding and respecting your partner’s strengths
MBTI can help you accept each other’s differences.
For example, in the case of an introverted and extroverted couple, they can understand each other’s needs.
Also, by knowing the differences between feeling and thinking types, they can respect each other’s decision-making methods.
Applying MBTI in Friendships
MBTI can potentially help deepen friendships.
By understanding your friend’s personality type, you can build better relationships.
However, it’s important not to view MBTI too rigidly.
The benefits of applying MBTI to friendships include the following:
- Promoting mutual understanding
- Improving communication
- Respecting individuality
Specific ways to utilize it include:
- Recognizing and leveraging your friend’s strengths
- Avoiding potential misunderstandings
- Enjoying each other’s differences
MBTI can help reduce conflicts with friends.
For example, if you’re Judging and Perceiving type friends, you can understand differences in how you make plans.
Also, by knowing the difference between Sensing and Intuitive types, you can enjoy diverse perspectives.
Utilizing MBTI in Child-Rearing
MBTI can help deepen understanding between parents and children in child-rearing.
By knowing your child’s personality type, you can understand appropriate ways to interact with them.
However, respecting your child’s individuality is most important.
The benefits of utilizing MBTI in child-rearing include the following:
- Understanding your child’s strengths
- Improving communication
- Understanding learning styles
Specific ways to utilize it include:
- Suggesting play methods suited to your child’s preferences
- Setting up learning environments suited to your child’s characteristics
- Understanding the thinking behind your child’s behavior
MBTI can potentially help improve parent-child relationships.
For example, with an introverted child, you can understand the importance of alone time.
Also, with a feeling-type child, you can recognize the importance of emotional expression.
Career Choice and MBTI
MBTI can potentially serve as a reference for career choice.
By knowing your personality type, you can see careers that suit your aptitude.
However, deciding your career based on MBTI alone is dangerous.
The benefits of utilizing MBTI in career choice include the following:
- Deepening self-understanding
- Understanding suitable job types
- Understanding work style tendencies
Specific ways to utilize it include:
- Exploring careers that match your personality type
- Understanding workplace environment preferences
- Considering career paths

MBTI can potentially help improve human relationships in the workplace.
By understanding the personality types of colleagues and supervisors, you can build cooperative relationships.
However, caution is required when using MBTI in the workplace.

- Leveraging individual strengths
Specific application methods include the following:
- Reference for team formation
- Adjusting leadership styles
- Optimizing task assignments
MBTI has the potential to help improve workplace atmosphere.
For example, decision-making is improved by balancing thinking and feeling types.
Additionally, project management becomes more efficient by leveraging the characteristics of judging and perceiving types.
Differences from Other Personality Tests
Comparison between 16personalities and MBTI
The famous “16personalities (16 Personality Types Test)” and MBTI are actually different.
Specifically, there are the following differences:
- 16personalities is based on “MBTI” and “Big Five”
- This is written in the “Our Approach” section of “Our Theory” on the 16personalities English page
- The neuroticism dimension of the Big Five is added as Identity (the final A and T) in 16personalities
- 16personalities provides more detailed personality descriptions
- MBTI has an official certification system
16personalities uses more approachable expressions. For example, it gives names like “Adventurer” and “Mediator” to each type.
Also, 16personalities can be taken online for free.
On the other hand, MBTI emphasizes interpretation by professionals. It aims for deeper self-understanding and understanding of others.
However, there is debate about the scientific evidence for both.
Differences between Big Five and MBTI
Big Five and MBTI are personality theories with different approaches.
Specifically, there are the following differences:
- Big Five measures five traits continuously
- MBTI classifies into 16 types using four axes
- Big Five is more academically supported
Big Five measures the following five traits:
- Openness
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism
In contrast, MBTI judges personality using four axes.
Big Five perceives individual differences as continuous (e.g., extraversion 3.8 points).
On the other hand, MBTI takes a dichotomous approach (e.g., E or I).
This Big Five is based on statistical methods and is considered more scientific.
However, there are also research papers suggesting correlations between Big Five and MBTI. Combined with HEXACO, which will be introduced next, the following relationships may exist.

Comparison of Characteristics Between HEXACO Model and MBTI
The HEXACO model and MBTI capture personality from different perspectives.
This HEXACO is a relatively new model that measures personality through six factors.
- Honesty-Humility
- Emotionality
- Extraversion
- Agreeableness
- Conscientiousness
- Openness
In contrast, MBTI judges personality along four axes.
The HEXACO model enables a more multifaceted understanding of personality. The “Honesty-Humility” factor is particularly distinctive.
The HEXACO model has also shown its usefulness in cross-cultural comparative studies.
Finally
Everyone, has your understanding of MBTI deepened?
MBTI is an interesting tool for understanding your personality, but we’ve learned that it’s not omnipotent.
MBTI is helpful for understanding your personality tendencies, but that’s only one aspect.
Personality is complex and multifaceted, so you can’t understand everything through MBTI alone.
Therefore, it’s important not to consider MBTI results as absolute, but to regard them as a reference.
Also, MBTI has scientific limitations.
There are problems with the approach of categorizing personality into 16 types, and there are issues with reliability and validity.
So it’s necessary to not overrely on MBTI results and view them critically.
What’s important is using MBTI appropriately.
It’s crucial to understand that MBTI only shows one aspect of personality and make comprehensive judgments by combining it with other information.
May you all skillfully use MBTI and walk your own unique path in life!
