What is the main difference between INFJs and INTJs?

  • Outwardly, INFJs are more likely to go along to get along than are INTJs. Both types are studious, but INFJs lean more toward liberal arts, whereas INTJs lean more toward science and technology. Don't overemphasize the leaning; individual preferences can have a wide range.
    • How does one get the information about these personality types? I know I am an INTJ through my reaction to people's comments here, but how do you get the formal diagnostics?
      • There is a ton of stuff on the Internet. Just take it with salt, because there are a lot of people confidently asserting things with little evidence to back them up, and the temperament sorter idea is oversold. You can also find lots of tests on line. Myers-Briggs style scoring is based on common sense notions, so there are lots of tests that are good enough.

        You might want to read either _Please Understand Me_ by David Keirsey and Marilyn Bates or _Please Understand Me II_ by David Keirsey. (You don't need both.) They come with tests.

        You might also want to read _Gifts Differing_ by Isabel Briggs Myers. Myers and Keirsey interpret the temperament sorter somewhat differently. Myers takes a far more Jungian approach.

        Personally, in my lay opinion, I think this style of temperament sorter mostly has power because it correlates with four out of the five Big 5 personality scales. The Big 5 Model (also known as the Five Factor Model), unlike the Keirsey or Myers-Briggs Temperament Sorters, has received a lot of academic interest and has become the reference model for psychologists studying personality. Go here if you want to take a Big-5 style test:

        This is David Keirsey's website:

        www.keirsey.com/

        He has a link to his temperament sorter on the first page.
      • You can take the official new MBTI(r)Complete through my website, www.TypeInsights.com. It's the latest version, with online facilitation, so there's no in-person validation. If you prefer to do a full validation/learning experience, I offer that too, through the same site. It all depends on how thorough you want to be. You can chase it around on the internet, but heaven help you sorting out the wheat from the chaff, and the free online quizzes aren't psychometrically verified. It will come as no surprise to you that I think a full self-discovery experience with an experienced practitioner is the best method -- which is why I offer that service. And I also understand that's not for everybody, and some people are unwilling to spend anything to discover their true identity. ;-)

        What do you want to invest? Which "diagnostic" has the most impact for you?
        • Oh, I'm pretty sure I am an INTJ just from reading some of the posts you guys have put here. I have never heard about temperament sorts, and wanted to learn more about it.
    • I agree that INFJs lean toward liberal arts and INTJ's are often in science, engineering or some form of career that still involves science as a background. I also think that the "F" function being developed in INFJs makes them more able to express emotions and or affection. It appears that INTJs will think inside their heads a lot but be unable to express things as freely or as often as INFJs would.
      • i dunno about this. i'm an INTJ and i definitely like science, but when it comes to science classes in school, i always did poorly. My mom and brother (which is rare for males) are INFJs, and I'd have to say the thing that is the biggest difference is their 'cooperation' vs. my "utilitarianism'. [I use quotes becuase they are Keirsey's words.] NFs are known for their want of harmony and NTs just want to explain everything.
    • I'm in doubt about my INTJ-INFJ as well.

      On the one hand, I've studied mathematics and organise about everything in statistics, spread sheads etc. I wouldn't have come far in descriptive science or anything practical.

      On the other hand, I have strong feelings about good vs. evil as in the ancient manichean religion (spiritual world is good, material world is evil) and distinguish between good and evil programming languages,("lisp is good, java is evil") and I strictly oppose logical positivism and empiricism in any science, and I feel much more comfortable with the philosophy of Schopenhauer (INFJ) than Nietzsche (INTJ)

      Does that make one of INTJ or INFJ more likely?
      • Your feeling function sounds introverted to me, which would indicate the INTJ pattern.

        INTJs have tertiary introverted Feeling, which can be quite inflated at times -- and sometimes causes INTJs to suppose they might be "Fs." (I don't typically use that label myself.)

        It's important to look at the *whole* pattern, not just focus on the letters that are visible in the code.

        I hope this helps.... :-)
  • I would say the major difference is around Temperament patterns. They have dramatically different core values and needs. (I'm an INFJ married to an INTJ.)
  • I don't care. I love them both!!! :D

    Seriously, I dated both types. Both are very deep. And yes INFJ is more arts inclined while INTJ is more science inclined.
  • Unsu...
     
    I'm an INTJ, and have a friend who's an INFJ. He took one of those tests online, and in response to the result of INFJ he said:

    "I don't like the J, it sounds judgmental."

    Which, of course, proved it beyond all doubt.
  • I think INFJs have a more idealistic motivation for a specific cause. Stuff like "world peace", etc. would be very motivating to an INFJ. INTJs are more concerned with practical means of getting things done in general, but I think these are just generalizations. You can have an INTJ with a very developed F side and be very idealistic. I think it's good to think of it more like a stereotype...

    • Hi

      My first two tests done in different styles came back INFJ and then another one turn out borderline INTJ.

      I can see how I stradle those points as noted by warren.

  • The difference is so huge.

    My boyfriend is a strong INFJ, I am a quite strong INTJ. The differences between us are just massive. In reading into his type I could no comprehend just what it meant, but now I see.

    INFJ's, at least at the more extreme level, are intense people with a highly developed intuition. This is in relation to people. If my boyfriend makes a statement on someone, it is usually right. This is an understatement. I cannot explain it but he has an amazing sense and understands people so so SO well that you must experience it. The books say some people wonder if its a sixth sense sort of thing. It can sometimes seem like that.

    Outside of that, my experience shows me that INFJ's can act rational too however they are far FAR more inclined to get emotional and are a lot more sensitive than INTJ's. While I can brush things off quite easily and move on INFJ's find that hard to do. They cannot brush off criticism from people that they hold close as easily, they are far more likely to take it to heart.

    INFJ's are intense people. An outsider wouldn't see it, but get close and you will find they are intense. They are far from easy going. They hold strong opinions, particularly concerning issues that deal with morality. They are very moral people who hold to their values. They champion their morals. They are not necessarily morals that we would associate with moral people, like say being an environmentalist. He is a strong right wing liberal, which while not normally done so he is like this because he finds it the most moral way to be. INTJ's tend to be less concerned with morals more concerned with getting what we want. We will be more likely to be quiet about our morals rather than champion them if it will help us get something.

    INFJ's are highly intelligent, too.

    They get along with people because they understand people. INTJ's don't. We just plain simply don't most of the time but INFJ's do, so they can appear to be people persons, but they don't want to be. They close themselves off except to a very few amount. Then they open up and they are immensely less cold. To those they shut themselves off from, they may be liked and they may be friends but their attitude towards them is far colder in comparison. INTJ's are just cold all around. We aren't emotional- and if we are we aren't in touch with our feelings. We don't have an overly emotional person hiding inside us waiting to unleash itself onto someone worthy.

    INTJ's and INFJ's are both highly imaginative and live inside our heads however what we daydream about is entirely different.

    INFJ's are certainly attracted to the social sciences, INTJ's attracted to technology and science (though I myself have a foot in both grounds but am leaning towards technology and science)

    The main difference is just where our heads are at. INTJ's, we use our intuition for other things- it is developed for other things. I have a knack for projects. Running them, creating them, very complex things. Hence why I fit the term "strategist" quite well. We are much more cold, emotionally, but we still have great fun. For INTJ's, their intuition lies in people, and feelings, which is why they are born mediators. They are the emotional version of us.
  • Is it possible to start testing as an INTJ? I've tested as INFJ since highschool but I just turned twenty and I now test as INTj. Could this be caused by my tertiary function is starting to develop?
    • I mean "Could this be caused by my tertiary function starting to develop?" lol. oops.
      • I would say so; still it depends, do you think it is that way? how well do u apretiate logic and rational thinking?

        I'm an INFJ definitely, i don't doubt it I'm in touch with emotions and i love it. So some people mean we have a 6th sense that might be true, i get really good feelings about things (not only people as might be thought) and I'm usually right; the actual reason why or why not is irrelevant, it works.
        Yet my tertiary function is as well developed as my Feeling; I'm very good at science and logical abstract theorizing and proud to say it; So i can solve things in a rational manner quite easy, that since i was a child. I'm actually studying mecatronics in Germany so i think i can solve problems quite easily.

        I found the balance between being pure logical and approaching with feeling; i actually enjoy to have a discussion with an INTJ while i find the lack of feeling somewhat amusing it really helps to feel grounded and real ;) In some cases it's just better to use that abstract thinking in a logical manner to solve a practical problem; but as for dealing with people i find it better to use this intuitive feeling and so to say "let the solution come to you"; I also think that's a great approach when you stay in front of an equation which doesn't seem to like to be solved ;)

        So i guess were not that different you might be an emotional type, which developed rational thinking then again i would have to actually read a couple more of your posts to be 100% sure ;)

        ------------------------------

        Btw. wussies?? come on... talking about letting your lack of feeling be an excuse for pure impersonal reasoning LOL i would say grow up ;) but don't get me wrong it's not a joke, i actually mean it; The development of the tertiary function comes with maturity. Don't defend yourself, accept ;)
        • I am an INTJ married to an INFJ. There are some serious fights in our house at times because of our differing thought processes. She often criticizes me for my ruthless insensitivity and at times I do not appreciate her empathic nature, but we are a strong couple nevertheless because our intuition mellows us out. I don't think either INTJs or INFJs are superior to one another. We are just different branches of the same tree.
  • Unsu...
     
    Well, I am an INTJ and my mother is an INFJ. We can be very similar, but there are some very fundamental differences. Obviously, she is much more sensitve than me ane she has better people skills. Although one notable thing about her (which I have read is quite common with INFJs) is that she tends to get very paranoid about disaster. One website referred to the INFJ as the 'conspiracy therorist'! :) We both had a good laugh over that one. I find INFJs intrinsically sweet, although they do take things very persoanlly sometimes and over analyse peoples motives. This also applies to my fiance, although he is an ENFJ.
