Recently, Korea has been swept up in an MBTI craze. Is it the same in your country? Nowadays, when going on a blind date, meeting friends, or encountering new colleagues at work, it's common to ask, "What's your MBTI?"
What is MBTI?
MBTI stands for Myers-Briggs Type Indicator, a psychological test used to classify personality types.
The Structure of MBTI
- Extraversion (E) vs. Introversion (I): How one gains energy. Extroverts gain energy from interacting with others, while introverts recharge by spending time alone.
- Sensing (S) vs. Intuition (N): How one gathers information. Sensing types focus on concrete facts, whereas intuitive types rely on abstract concepts.
- Thinking (T) vs. Feeling (F): How one makes decisions. Thinking types prioritize logic and principles, while feeling types value emotions and relationships.
- Judging (J) vs. Perceiving (P): One’s approach to life. Judging types prefer structure and planning, whereas perceiving types embrace flexibility and spontaneity.
MBTI Personality Types
The combination of these indicators results in 16 personality types, represented by four-letter combinations such as ISFJ or ENTP.
MBTI tests require individuals to answer a series of questions about themselves, making the results feel relatively accurate. In short, MBTI provides a framework to describe "who I am." Instead of expressing one's hobbies or interests, MBTI allows people to present themselves in a defined manner when meeting new people.
With MBTI, there may no longer be a need to explain yourself in detail or take time to understand others. You can simply determine compatibility in advance by identifying which MBTI types clash with or complement your own.
Why Are We So Enthusiastic About MBTI?
To understand this, we must first talk about previous personality theories.
Western societies might find this surprising, but before MBTI, blood type personality theory was extremely popular in Korea.
In the past, it was common for friends to ask each other, "What's your blood type?" just like asking for a name. Everyone in close friend groups knew each other's blood type. This theory categorized people into A, B, AB, and O types, assigning personality traits like "A types are timid" or "AB types are eccentric." People even guessed blood types based on behavior, confidently saying things like, "Let me guess, you're a B type, right?" A popular webtoon even focused on blood type personalities.
Beyond blood types, Koreans also relied on the 12 zodiac animal signs based on birth year and Western astrology's 12 zodiac signs to predict fate and character traits. However, these were more commonly used for fortune-telling rather than personality assessment.
MBTI and the Search for Self-Identity
Like everyone else, I struggled with the question, "Who am I?" during my teenage years.
It wasn’t easy to figure out, as I was influenced by parents, friends, teachers, and even the media. At that time, I didn’t realize that adolescence is a period of trial and error, where flexibility helps shape one's identity. The uncertainty of not knowing who I was made me anxious, and I wanted to define myself quickly.
Using blood type or zodiac signs as a predetermined identity was an easy way out.
Nobody questioned it. A fate-based personality provided a sense of stability.
MBTI as a Convenient Justification
Many young people today are uncertain about the future—what career to choose, what kind of life to lead. In this uncertainty, MBTI not only defines their personality but also offers an excuse.
- "I'm naturally an introvert."
- "I'm naturally a thinker."
Even rude behavior or difficulty adjusting to new environments can be dismissed as inevitable because "that's just my MBTI."
MBTI: A Useful Tool or a Limiting Label?
MBTI is not a fixed trait like blood type or zodiac signs; it represents one's self-perception at a given time. The test is meant to help individuals identify weaknesses and improve themselves. However, many still treat MBTI as an unchanging fate.
Compared to blood type personality theory, MBTI feels far more scientific and credible because it offers 16 personality types instead of just 4. But deep down, we all know that no test can perfectly define who we are.
Yet, in today’s polarized world, MBTI provides an easy way to categorize people as "like me" or "different from me." It also offers a convenient excuse in uncomfortable situations.
But does it really matter? I don’t see this as a problem—after all, trends come and go.
The only thing to watch out for is this: Don’t let MBTI put you in a box.
People change. The person you were in your teens is different from who you are in your 30s. Your values, personality, and way of speaking evolve over time—and they should.
If you confine yourself to a personality type, you might stop growing.
But if you embrace change, you might discover that your MBTI has also changed over time.
So, what’s your MBTI?
