What Is MBTI? A Simple Guide to Personality Types in Dating

You may have seen someone write:

“I’m an INFP.”

Or perhaps a date has told you:

“I’m an ENTJ. What are you?”

If you have no idea what those four letters mean, you are not alone.

MBTI has become a popular way for people to talk about personality, especially in dating. Some people even include their personality type in dating profiles.

But what exactly is MBTI?

And more importantly, can it actually help you understand yourself and the people you date?

Let’s start with the basics.

What Is MBTI?

MBTI stands for Myers-Briggs Type Indicator.

It is a personality framework that describes people through four sets of preferences. Put those preferences together and you get one of 16 personality types.

You may have seen combinations such as:

INFP, ENTJ, ENFP, ISTJ, INFJ, ESTP

At first, they can look like random letters. They are actually quite simple once you understand what each letter represents.

E or I: Extraversion vs. Introversion

This is probably the pair most people already recognize.

But it is not simply:

E = outgoingI = shy

Think about it more as where you naturally direct your attention and how you tend to recharge.

Someone with an E preference may enjoy interacting with people, talking through ideas, and getting energy from the outside world.

Someone with an I preference may prefer more internal processing, smaller social settings, and time alone to recharge.

In dating, this difference can show up very quickly.

One person may want a busy Saturday with friends, dinner, and another event afterward. The other may genuinely enjoy the dinner but want Sunday completely free.

Neither person is wrong. They may simply have different social rhythms.

S or N: Sensing vs. Intuition

This pair describes how someone tends to take in information.

Someone with an S preference often pays more attention to concrete information, details, experience, and what is happening now.

Someone with an N preference may naturally focus more on patterns, possibilities, ideas, and what something could become.

Imagine two people discussing a new job opportunity.

One might ask:

“What is the salary? What are the hours? Where is the office?”

The other might ask:

“Where could this career take you in five years?”

Both are useful questions. They simply approach information differently.

T or F: Thinking vs. Feeling

This pair often causes misunderstanding.

It does not mean that Thinkers do not have feelings or that Feelers do not think logically.

Instead, it describes tendencies in how people evaluate situations and make decisions.

Someone with a T preference may naturally focus on logic, consistency, and what seems objectively reasonable.

Someone with an F preference may give more weight to personal values, relationships, and how a decision affects people.

This difference can become very visible during conflict.

One partner may immediately start looking for a solution. The other may first want to feel understood.

Sometimes the solution-oriented person thinks:

“I’m trying to help.”

And the other person thinks:

“I don’t need you to fix it yet. I need you to understand me.”

That small difference can create surprisingly big misunderstandings in relationships.

J or P: Judging vs. Perceiving

This is another pair that is easy to misunderstand.

“Judging” does not mean judgmental. “Perceiving” does not mean perceptive.

This pair is more about how people tend to approach structure and the outside world.

Someone with a J preference may feel more comfortable with plans, decisions, schedules, and closure.

Someone with a P preference may prefer flexibility, keeping options open, and adjusting as things develop.

You can see this even when planning a date.

One person wants to know:

“Where are we going? What time? Do we need a reservation?”

The other says:

“Let’s meet around 6 and see what we feel like doing.”

For one person, that sounds spontaneous. For the other, it sounds stressful.

How Do the Four Letters Work Together?

Now the types start making sense.

Take INFP:

I — Introversion

N — Intuition

F — Feeling

P — Perceiving

Now compare that with ENTJ:

E — Extraversion

N — Intuition

T — Thinking

J — Judging

You can immediately see that they share one preference, N, while differing on the other three.

That does not mean they are incompatible.

It simply gives us a starting point for asking better questions.

How much social interaction does each person need?

How do they make decisions?

How much structure do they want?

What happens when they disagree?

Those questions are much more useful than asking whether INFP and ENTJ are a “good match.”

What Are the 16 MBTI Personality Types?

The four preference pairs create 16 possible combinations:

ISTJ · ISFJ · INFJ · INTJISTP · ISFP · INFP · INTPESTP · ESFP · ENFP · ENTPESTJ · ESFJ · ENFJ · ENTJ

You may recognize your own type immediately.

Or you may take a test and feel that you are somewhere between two types.

That is okay.

Personality is more complicated than four letters.

Can MBTI Tell You Who You Should Date?

This is where I would be careful.

MBTI can be a useful tool for conversation and self-understanding.

It should not become a dating filter.

I would not recommend rejecting someone simply because:

“I’m an INFJ and he’s an ESTP.”

Or:

“The internet says ENTJs should date INFPs.”

Real compatibility involves much more.

I want to know about your values, lifestyle, family expectations, communication style, emotional needs, career priorities, and relationship goals.

I also want to understand how you deal with conflict, how you show affection, what commitment means to you, and of course, whether there is attraction.

Four letters cannot answer all of those questions.

How I Use Personality in Matchmaking

For me, MBTI is interesting because it can help start conversations that might otherwise be difficult to begin.

Instead of simply asking:

“What personality type do you want?”

I might want to understand:

Do you enjoy being with someone more social than you?

Do you prefer someone who makes plans?

When you are upset, do you want emotional support first or solutions first?

Do you like spontaneous people, or does too much spontaneity make you uncomfortable?

Do you need a lot of personal space?

Do you enjoy discussing abstract ideas, or do you prefer talking about what is actually happening in your life?

Now we are learning something useful.

Your MBTI Type Is a Starting Point, Not Your Identity

If you discover that you are an INFP, ENTJ, ENFJ, ISTJ, or any of the other types, have fun exploring it.

Read about it. Notice what sounds familiar. Notice what does not sound like you.

You might even ask someone you are dating about their type and compare your answers.

It can lead to a very interesting conversation.

Just remember that I am much more interested in the person behind those four letters.

When I meet someone for matchmaking, I am not trying to match an INFP with an ENTJ.

I am trying to understand two real people.
