Do you ever feel like you’re not connecting to certain parts of your type description? Many, many ISTJs mistype as INTJs and wind up feeling confused when they read articles that don’t resonate with them. I know how frustrating that can be! I hope this article can make clarifying your type easier.

Why There Are So Many Mistypes

Most online tests rely on the letter dichotomies (I/E, S/N, T/F, J/P) to type someone. They don’t focus on the cognitive functions, which are the foundation of personality type. Because of this, if someone scores just a little higher on one dichotomy than another the online test will push out a possibly inaccurate result. This happens often with the S/N and J/P preferences.

Another reason that online tests mistype people is because most tests have an intuitive bias. They assume certain words, like ‘possibilities’, ‘imagination’, and ‘deep’ apply only to intuitives, when in fact sensors can also enjoy possibilities, be imaginative, and enjoy deep conversation.

Example:

John Smith is an ISTJ who is 34-years-old. He works as a bank executive, but during his free time he enjoys building furniture in his workshop. He also loves computers, and has spent a lot of time trying to create customized desktops for his friends and family members. He enjoys watching Star Wars and reading Isaac Asimov. He’s starting to think more about the meaning of his life and what kind of legacy he wants to leave behind for his young children.

One day, John sits down at the computer and takes the 16 personalities online test. The test asks him to weigh in on statements like “You rarely do something just out of sheer curiosity”, or “Your mind is always buzzing with unexplored ideas and plans”. John thinks about how curious he is about how machines work or how he enjoys experimenting with computers to see if he can build his own. He thinks about how excited he is to create new furniture in his workshop. He thinks about how he’d like to turn his love of carpentry into a business. He nods to himself. Yes! His mind is always buzzing with unexplored ideas and plans. Yes, he is very curious! He selects ‘Strongly Agree’ when he takes the test.

What John doesn’t realize is that 16 personalities asked those questions to define a preference for sensing or intuition. Those questions triggered an intuition preference. As a result, John gets an INTJ result. There are many things that resonate with John about the INTJ type description. He’s logical, objective, hard-working, private, reserved, intellectual. So he’s happy with that type for a long time.

Two years later John starts to read more into the INTJ type, and he realizes he’s not really sure how he uses Introverted Intuition (Ni). Sure, he gets hunches from time to time, but it isn’t a driving force in his life. He doesn’t think in symbols or metaphor, and his conversation tends to be on the literal side. He prides himself on being down-to-earth. These qualities don’t seem to match up with the abstract/symbolic thinking of the INTJ. Is he mistyped? After spending a few months exploring the cognitive functions in-depth, he realizes he’s actually an ISTJ.

What INTJs and ISTJs Have in Common

INTJs and ISTJs share two cognitive functions. You can see these in the graphic below:

INTJs and ISTJs both have auxiliary Extraverted Thinking (Te). This means that they will both make decisions using impersonal analysis, objective logic, and by looking at pros and cons.

INTJs and ISTJs both have tertiary Introverted Feeling (Fi). This means that they will both have a strong set of values that they live by and adhere to. They are well aware of their own emotions, but don’t like to let those influence their decisions. They are private about their feelings, but that doesn’t mean they don’t have them.

And then there’s the preferences. INTJs and ISTJs both have a preference for introversion; they will both want to reflect before speaking and consider before making a decision. They will both try to be organized and methodical in their projects and plans.

How INTJs and ISTJs Perceive Differently

ISTJs use Introverted Sensing (Si). Si thinks about and sees the details. It is concerned with provable facts and the tried-and-true technique. ISTJs are practical, down-to-earth, and focused on realistic objectives and problems. Si gives the ISTJ a fondness for recalling past events in detail. They enjoy reflecting over their favorite memories, and they enjoy repeating their favorite daily activities. They like knowing what will happen, what to expect, and they like to create a daily routine that gives them stability and security.

ISTJs are planful for the future; they like to know how to create a good life for their family, for their children, grandchildren, and great-grand children. Their plans usually involve tangible realities; putting together a will, saving for a new house, building a workshop, doing something that has  a utilitarian result.

Some Facts About ISTJs:

– They are down-to-earth and outwardly matter-of-fact.

– They absorb and place importance on proven facts, which they can recall swiftly.

– They tend to be hard-working and responsible.

– They have a respect for history and traditions.

– They enjoy tried-and-true techniques.

– They focus on what already exists and prefer to deal with concrete realities, facts, and examples.

– They form future forecasts based on what they’ve learned through personal experience.

– They are considered the most practical of all the introverted types (according to Isabel Briggs Myers research in her book Gifts Differing)

– They thrive on routine and like to know what to expect.
– They are often described as “conservative”, “practical” or “level-headed”.

What Other Typologists Have Said About the Introverted Sensing Type:

“He may be conspicuous for his calmness and passivity, or for his rational self-control.”
– Carl Jung, Psychological Types

“A person who sees the world through introverted sensing would probably, therefore, have a reliable sense of the historical background of any familiar situation. And this would likely make them very stable and reliable, most comfortable in activities they’ve encountered before.”
– Mark Hunziker, author of Depth Typology: C. G. Jung, Isabel Myers, John Beebe and The Guide Map to Becoming Who We Are

“Most people are familiar with the notion of “learning through experience.” This can be associated with Si, which guides and informs our behavior by consulting past experiences. To be sure, all types rely on memory and past experience to some extent, but for Si types the past is granted higher priority and greater authority.”
– Dr. A.J. Drenth, My True Type: Clarifying Your Personality Type, Preferences & Functions

The INTJ’s Perception

INTJs use Introverted Intuition (Ni). Ni thinks about the big picture and is in love with theories and abstract possibilities. Thus, INTJs are driven by their hunches and their insights into the future or how things will play out. They don’t enjoy reminiscing and care little for the tried-and-true technique. They want to find new ways to do things. They want to explore pathways that nobody else has and are more interested in trailblazing a new idea than improving on an existing one.

INTJs are quick to see patterns, trends, symbols, and hidden meanings. They can focus so much on the future that they forget about what’s happening “right now”. They are individualistic, extremely independent, and find routine and practical matters boring. They are driven their inspirations, and they can’t always pinpoint where that inspiration came from. Because they are so driven by their hunches, knowing what to expect every single day can frustrate them and feel monotonous.

Some Facts About INTJs:

– They are driven by an inner vision of how things could play out in the future

– They focus on potential and deal with abstract concepts, symbols, archetypes, and ideas.

– They are determined to discover and pioneer new roads and unveil new research. The tried-and-true technique bores them.

– They tend to find the routine and the practical day-to-day aspects of life mundane.

– They keep a constant eye on the big picture and are less aware of all the details.

– They are very strategic and can easily piece clues together.

– They see underlying patterns and clues that help them to determine a future forecast.

– They are often referred to as “visionary” or “grandiose”.

What Other Typologists Have Said About the Introverted Intutive Type:

“If their focus is more abstract, vague, distant, and “impractical”, generating metaphysical insights that are hard for them to explain except through metaphors; if they seem to consider everything….all in the interest of imagining distant, vague possibilities, gaining a personal sense of knowing, and divining meaning and purpose – this evinces use of well-developed introverted intuition.”
– Mark Hunziker, author of Depth Typology: C. G. Jung, Isabel Myers, John Beebe and The Guide Map to Becoming Who We Are

“Introverted intuition perceives all the background processes of consciousness with almost the same distinctness as extraverted sensation registers external objects. For intuition, therefore, unconscious images aquire the dignity of things.”
– Carl Jung, Psychological Types (The Collected Works of C. G. Jung, Vol. 6) (Bollingen Series XX)

“The introverted intuitive moves from image to image, chasing after every possibility in the teeming womb of the unconscious, without establishing any connection between them and himself.”
– Carl Jung, Psychological Types (The Collected Works of C. G. Jung, Vol. 6) (Bollingen Series XX)

“The introverted intuitive has little consciousness of his own bodily existence or of its effect on others. The extravert would say: “Reality does not exist for him, he gives himself up to fruitless fantasies.” The perception of the images of the unconscious, produced in such inexhaustible abundance by the creative energy of life, is of course fruitless from teh standpoint of immediate utility. But since these images represent possible views of the world, which may give life a new potential, this function, which to the outside world is the strangest of all, is…indispensable to the total psychic economy.”
– Carl Jung, Psychological Types (The Collected Works of C. G. Jung, Vol. 6) (Bollingen Series XX)

What Influences the IXTJ Decision-Making Process

INTJs and ISTJs are both logical, objective, and focused on pros and cons. However, the INTJ’s decisions will be driven by an unconscious vision or perception of how things will play out in the future. The ISTJ’s decisions will be driven by personal experience, concrete facts, and a utilitarian practical application.

The Inferior Function and “Grip” Stress Responses

ISTJs have inferior Extraverted Intuition (Ne). They tend to be skeptical of “hunches”, theoretical, unproven facts, or experimenting with new approaches to something they already know how to do through experience.

INTJs have inferior Extraverted Sensing (Se). They tend to be skeptical of their sense-impressions, other people’s personal experience, and they prefer to live in the future rather than focusing on the moment.

When ISTJs experience extreme, chronic stress, they can fall into the grip of Extraverted Intuition (Ne). When this happens, the ISTJ can see endless negative possibilities for the future. They may become overwhelmed with ominous perceptions about what “could” happen. They will become especially cautious, worried, and focused on creating security under stress. You can find out more about this here.

When INTJs experience extreme, chronic stress, they can fall into the grip of Extraverted Sensing (Se). When this happens, the INTJ can become indulgent and impulsive. They may engage in reckless activities, make spur-of-the-moment decisions, or become experimental with new foods/drinks/physical activities or other sensation-based experiences. They will become less careful and more physically reckless during extreme stress. You can find out more about this here.
