INTJ Overview

Key principles of the INTJ personality type with global survey data

Page contents:

People with INTJ type personality (sometimes referred to as 'architects') see the world around them as one big complex puzzle they can solve. They tend to be ambitious and enjoy strategizing using logic. They think big and strive towards their goals, but prefer to keep their visionary plans to themselves.

INTJ Principles

What are the core principles behind the type INTJ?

People with INTJ personality type calculate the world around them, and believe they can achieve anything if they just get the strategy right. They use vision and analysis to build the world they want. They often keep things private, and work things through in their mind rather than share them openly.

Rational and quick-witted, INTJs may struggle to find people who can keep up with their non-stop analysis of everything around them.

  • They treat life as one big strategy game
  • They have a thirst for knowledge
  • They question everything
  • They prefer quiet introspection over socializing

All in the mind

An INTJ believes that, through willpower and intelligence, they can achieve even the most challenging of goals. But they may be cynical about human nature more generally, assuming that other people are not their equals.

INTJ is the rarest personality type. They are ambitious, determined, and single-minded sometimes to a fault.

Improvement by analysis

INTJs question everything. In their quest to find better ways of doing things, they aren't afraid to break the rules or risk disapproval. INTJs want to be successful, in everything they do. They bring a single-minded drive to their passion-projects, applying the full force of their insight, logic, and willpower to make things happen. They enjoy the challenge of a big project.

INTJs believe they can solve most of life's challenges if they just think it through carefully enough.

The lone wolf

This personality type comes with a strong independent streak. INTJs don't mind acting alone, perhaps because they're impatient waiting around for others to catch up with them. They also generally feel comfortable making decisions without asking for anyone else's input. At times, this lone-wolf behaviour can come across as belligerent or insensitive, as it fails to take into consideration other people's thoughts, desires, and plans. But to an INTJ, they know what needs to be done and they get on with it.

Are you a calculating tactician? Do you see life as a game of chess? Then perhaps you're an INTJ.


An INTJ values truth and depth of relationship. So some common social practices like small talk for example may seem pointless to them. At times, INTJs may wonder if dealing with other people is even worth their time. But like any personality type, INTJs do crave social interaction, they’d just prefer to surround themselves with people who share the same values and priorities. Often, the best way for an INTJ to enjoy socializing is for them to simply be themselves; their natural enthusiasm will come out and people who don't get them will simply drift apart and leave them to it - which is exactly what an INTJ would prefer.

INTJ: The Four Letters Explained

What does INTJ stand for?

The four letters of the INTJ personality stand for: (I)ntroverted, i(N)tuitive, (T)hinking, and (J)udging. Let's consider each of these four traits.



(I)ntroverted vs (E)xtraverted

An introvert is often thought of as a quiet, reserved, and thoughtful individual. They don't seek out special attention or social engagements, as these events can leave introverts feeling drained.

  • Prefer time to themselves
  • Find social interaction an effort
  • Have close circle of friends
  • Introspective and curious
  • Prefer writing to talking
  • Prefer working alone

Introverts and extraverts can be separated based on how they regain energy. Introverts prefer minimally stimulating environments, and they need time alone to recharge. Extraverts refuel by being with others.



I(N)tuitive vs (S)ensing

Intuitive types focus on impressions or underlying patterns of information they see. They prefer learning by thinking it through rather than by hands-on experience.

  • Remember the sense of events
  • Read between the lines and looks for meaning.
  • Like to see the big picture
  • Daydream about possibilities
  • Make decisions based on hunches

Intuitive types take a high-level view and may experience dissatisfaction when attention to detail is required. People with an Intuition preference doubt and test everything. They value innovation and imagination, and present information through figures of speech.



(T)hinking vs (F)eeling

Thinking types are objective. They make decisions based on facts. They are ruled by their head instead of their heart. Thinking people judge situations and others based on logic. They value truth over tact and can easily identify flaws.

  • Use logic and objectivity
  • Seek the truth
  • Value reason and rationality
  • Direct with people
  • Prefer facts to opinions

Thinking types are critical thinkers and oriented toward problem-solving. Thinking does not mean a person is without emotion.



(J)udging vs (P)erceiving

Judging types approach life in a structured, organized and carefully calibrated way, creating plans to help them achieve their goals. Schedules and to-do lists are comforting to them. They prefer knowing what they are getting into and feel frustrated in situations of ambiguity and change.

  • Act decisively
  • Organized and structured
  • Are finishers. They like plans and deadlines.
  • Like closure
  • Prefer structured setting

Judging types gain a sense of control by taking charge of their environment. They are self-disciplined and decisive, going for closure at the earliest possible opportunity to avoid stress.
