INTJ – The System Developer


INTJs are intellectuals who love a great challenge or a chance to learn. They are leaders that work with long term determination towards a desired personal goal. They are architects that structure and organize themselves and their life. They are philosophers that theorize and envision a possible future or an answer to a complex problem. They are writers that structure and organize their ideas into a bigger system or a coherent theory of everything. They are independent thinkers that always have their own answer, method or solution to a problem.

The System Builders

The INTJs are system builders – theoretical, introspective, and thoughtful. They prefer to spend a long time in contemplation, thinking about their next move, what they know, and how they can use information wisely. Particularly interested in creating puzzles and complex systems, INTJs are philosophers and architects. Using introverted intuition, they seek answers to the world’s many mysteries. Because of their weak extroverted sensing, they often spend much time away from others. Being away from others helps them go deep when studying the worlds many mysteries.

And using extroverted thinking, they become good judges of character and of complex systems. At their best, they are decisive and assertive, with an aura of confidence. They are quick to act and move on new logic and new rules. They are more concerned with implementing and putting logic to practice than with sharpening and double-checking the maths behind it. The question is: “Does it work in practice?”, not “How does it work?” But the architect is at best at the service of being a philosopher. INTJs ideally employ their extroverted thinking to help structure their theories and ideas.

INTJs are good directors and strategists. They often work long term behind the stages towards hidden goals. They need peace and balance and are at their best when they are self-composed visionaries. INTJs enjoy theorizing, speculating, and envisioning possible futures. They can predict with far greater accuracy and with objective reasoning than for example the INFJ. INTJs work with clear defined rules, rather than vague and symbolical terms. They structure, measure, and define their thoughts. Because defining introverted intuition with logic can be difficult, they are not afraid to let their intuition lead the way.

INTJs have an air of mystery around them. They can be sly and devious, but also show a sentimentality and inner warmth to those who have gotten to know them more intimately. INTJs are masters of dark humour and sarcasm, and show great insight into many areas of life. Usually, they are broad and hard to limit to one field, and more common as jack of all trades, with thoughts and opinions on many areas of life, even those where they know little. INTJs operate in the dark, always seeking answers to the more difficult questions of life.

They work with speculation and theories to try to reveal and understand dilemmas that they are facing. As philosophers, they like to detach from the world, looking at it from the big picture, outside of their own bodies. The goal is to reach a more pure and true understanding of things. Once able to form a hypothesis, they can with a lot of energy and hard work prove and communicate their theories with the help of extroverted sensing.

Common characteristics

INTJs seek and aspire towards success and development of ideas. You are cautious and take time to warm up to others, and you’re driven and business-oriented. You test and see if people are worthy of your trust. You’re ambitious and proactive but you can take many years before you put your plans in motion. You tend to have strong beliefs and a strong work ethic. And the INTJ tends to express their opinions openly and directly, without holding back. 

You enjoy small groups or intimate one-to-one interactions, but there’s no place like home. You love to take a step back and to think about things in depth. You’re intelligent and value efficiency and people who are able to think up smart ways to do things. As an INTJ, you have a knack for knowing if something is going to work and for estimating how successful something could be. You have a good grasp of what exactly it is that you want and how to get there. And you generally want something tangible, and you want your goals to have concrete rewards. As an INTJ, you are an objective decision maker and you don’t really believe in discussing your decisions with others in advance.

You take time to open up to others. You enjoy sharing your facts and engaging in logical discussions with others, and you may struggle with a bit of a temper. As an INTJ, you may appear stern and stoic, and somewhat hard to get to know. You mostly prefer being at home or somewhere where you can focus on your goals. You are introspective and highly capable of independent thought. You enjoy thinking up new solutions and new ways to solve problems.

Because of your love for progress and creativity, you tend to frown on traditions and social necessities. You find politeness to often be an obstacle and would rather people just state their opinions openly. This is somewhat paradoxical, because you have a tendency to become quite an authority yourself. INTJs are driven and proactive, almost to the point of becoming pushy about their goals. You’re secure and safe and rarely act recklessly. As an INTJ, you tend to be resistant to new ideas and to new suggestions. You’re firm about your beliefs and when you’ve made up your mind, it’s hard to lure you to the other side. Your ideal romantic partner tends to be the ENTP. Their love for logic, their ability to spread energy and ideas, and their openness to new ideas appeals to you greatly.
