INTJ vs ISTJ – 12 Vital Differences You Need to Know

Have you ever thought of the ways you communicate with others or deal with different problematic situations? It is hard to understand what happens in your inner self or a way to control your emotions, right?!

Based on the research on the Myers-Briggs type indicators, there are some different approaches in many areas of our lives.

The personality types presented by Myers-Briggs can be divided into many. But in this article, we focused on the main differences between two of them: the INTJ and the ISTJ personality types.

The INTJ (introverted, intuitive, thinking, and judging) and the ISTJ (introversion, sensing, thinking, judgment) seem to differ only in one letter. But actually, many other differences are worth mentioning.

12 Vital Differences You Need to Know About INTJ vs ISTJ

We have gathered the 12 vital differences between them, so you can learn to differentiate the two types.

To help with the reading, we thought it would be worth mentioning that INTJs are also called Architects, while ISTJs are called Logisticians.

Keep reading and check out some vital differences between these two personality types!

#1 Strengths and Weaknesses

For starters, let’s compare their strengths and weaknesses!

Architects, or INTJs, feel better when they have extended research before they can express any kind of opinion. It belongs to their nature to focus on deep analysis, so they are able to assure the results are not opinion-based.

Although they are generally open to new points of view, it is really tough to convince Architects without good arguments.

Logisticians, on the other hand, are righteous. Therefore, if you want to get closer to them, lying and manipulating behaviors are not the way and will probably push them away.

If an ISTJ makes you a promise, they most certainly will keep it due to the value they give to their own words. Being really loyal to people they committed with, Logisticians tend to avoid people who cannot follow the rules.

On the other hand, of course, both types have their weaknesses. Architects always have a strong sense of criticism. They are not known as people who easily forgive or forget mistakes. If you need them to follow you, it is really important that you make clear the reason why you are doing something. Otherwise, Architects will lead the way.

Logisticians do not measure words if they need to tell you the truth even though they understand it may hurt your feelings, it is natural to act based on their judgemental thoughts.

#2 Dealing with conflicts

In terms of INTJ vs ISTJ, INTJs are not that romantic. People who get involved with them will get used to not receiving flowers. When there is a problem to be solved, they go straight to the point, and, sometimes, their words may offend the ones trying to argue with them.

For trying to get to the central point immediately, Architects may sound insensible. But it usually happens as a consequence of their intellectual manners. They see a huge opportunity in getting into a relationship because, as their focus demands, conflicts might help them develop their growth.

In contrast, Logisticians are really romantic. They can offer a better relationship environment due to their will to create a pure and honest family home. Trying to avoid conflicts, Logisticians don’t act risky. They will always try to start a relationship with people they already know or with people they can easily connect with.

It might not be difficult to change the formal behavior of Logistician types. You can only break a promise, and everything will fall apart. Letters and letters will be written so you can understand the mistakes you have made.

#3 Just the way they are

Architects never try to change so they can get to know somebody. This is the reason why they are considered antisocial, but, in fact, they are not. Remember INTJs have strong opinions; based on that, people should be aware that Architect personality types will act just like they are, not changing their behavior to fit in any kind of situation.

Notably, Logisticians are good friends. They are loyal, they are humble, and they would do everything to help. If somebody needs a hand, ISTJs will be glad to be there and concentrate all the effort to make a difference. They insistently cause good impressions, and they are always requested.

#4 Intuition vs Reason

ISTJs are not really good at creating unrealistic things; they struggle when dealing with abstract ideas. They see symbolism as chaos, and it brings problems to their lifestyle.

Naturally used to foreseen issues, they need defined and well-drawn rules so their actions will become stronger. With this, they invest more time in ludic activities involving physical art, such as paintings that reflect a real vision of the world.

INTJs are intuitive, so they can focus more on the abstract world. Thereby, if you need good ideas to solve unimaginable problems, INTJs will effectively work on a plan to get the job done. People with Architect personality types love using their imagination to develop their own skills.

#5 Professional aspects

Nobody will ever hear such things as Architects settled down and decided to keep their steps on the same path for a long time.

When dealing with their careers, there are plenty of things to say: first of all, they are problem solvers, that is why it is really important to keep their star shining.

Even though INTJs may lock themselves inside, people with this type beg for being challenged. Thereby, it is right to say that Architects would fit in any role in a company.

As mentioned before, Logisticians will not be happy if any subordinate or employee skip steps of a procedure or do not follow the instructions as it was meant to be.

A huge problem can come out of this since they are so critical and inexhaustibly intense.

ISTJs need people who can adapt really well to a tiring and busy routine. On the other hand, they can get more than what they can deal with. It may stress people with this personality type and, consequently, bring fatigue.

#6 Relationships with kids

INTJs exist to be challenged, so even though kids are not likely to be so direct or focused on self-control, it may become a very special experience for people with this personality type.

Due to their dream of raising kids right, they tend to use appropriate approaches so the child’s age will not interfere with the expected result.

ISTJs are more likely to be connected with kids. Nevertheless, the way they decide to raise children is a lot stricter. Consequently, it is common to see sons and daughters of people with this type of personality turning into respected and proactive for society.

#7 Groups vs Individual tasks

People with the Logistician personality type tend to understand the importance of group work. They know people may be helpful, and working together can be a comfortable way to build things.

Even when ISTJs have control of the situation, they would rather be part of a team.

In spite of having the ability to deal with leadership, Architects would not work well in groups. People with this personality type prefer to give more than one hundred percent of their efforts to get to the results by themselves. It is not a matter of showing off, but to reinsure the necessity of doing everything by their own rules.

#8 Sense of freedom

When it comes to limiting their freedom, some differences appear.

INTJs do not deal well with people who want to ‘disbranch’ their potential. As already mentioned, they are really critical. But they may also give a headache depending on the boss they will reply to with those strong words.

If people with this personality type want to do something, their bosses must have a very good argument to stop them. Otherwise, bosses will only lose their admiration and will make them stop obeying as before.

On the other hand, people with a Logistician personality type tend to follow the rules and understand the different goals as their bosses demand. They are always willing to help by complying with authority and hierarchy.

#9 Cold vs Too emotional

While Logisticians show a great range of emotions, we can already say that Architects struggle when they have to let people know what they feel.

But it is not like Logisticians are weak or something like this. They understand emotions are irrational, and they try to fight against them, but it may be hard.

In the same way, people with the INTJ personality type know it may seem weak to demonstrate their feelings. That is why they tend to focus more on their ideas and not on their emotions. Sounding cold or not, Architects barely get frustrated because of that.

#10 Can they overcome their differences?

Of course, they can!

One can encourage the other, and it is easy to do. Architects must tell Logisticians that they are very good problem solvers, that their ideas and thoughts are brilliant.

Meanwhile, people with the Logistician personality type can recognize how creative and innovative Architects are.

But the thing is… Will they be able to do that? That is the one-million-dollar question.

#11 What can they do to avoid conflicts?

Well… That is a good thing to think about.

These two personality types seem to be far different from the other, but the truth is that they are more similar than they were meant to be.

If ISTJs want to keep the peace, they must avoid asking people with the Architect personality type to focus on very specific subjects.

But if INTJs want to keep a good relationship, they must focus on their speeches so as not to hurt ISTJs’ feelings.

#12 Romantic relationships

Logisticians are too emotional. Because of that, people must be ready for the number of questions they will ask. It is not personal. They just want to make sure you are the right person for them.

Architects, meanwhile, will prefer people who love to talk and bring lots of ideas to the table.


INTJs are more rational and grounded. They want to reach their goals, and they will do everything possible to make it happen. Although they seem cold and rude sometimes, they only act like this because of their potential to deliver the best they can.

ISTJs, in contrast, are emotional people and tend to focus on their personal growth but not by avoiding group work. As dedicated people, this personality type will always work hard and keep their promises.

Both personality types have their strengths and weaknesses, or better saying, their differences, but that does not mean they can’t get along. The thing is that they need to understand their differences and learn how to coexist to maintain a healthy relationship.
