This is the most important, but often one of the more difficult, things to do. Unless you know your actual type nothing else you try to do with the MBTI will work because it won’t be for you. It’s not easy; if this is new to you there’s a lot to learn. Even for someone like me, an INTP who loves figuring things out, it’s taken years. Luckily for you, though, I’ve done a lot of the work... but none of that will matter unless you do your part. Figuring out your type isn't easy, but most things that are worthwhile aren't.
If you still want easy though you can always take a free test. There are plenty of MBTI tests online - I've linked some of the better ones below - but there are problems. The main one is that many, if not most, of these tests were created by people who explicitly reject Jung and his ideas because they're trying to make the MBTI more acceptable to the scientific community. But when you cut the MBTI off from it's roots all you're left with is a cheap personality quiz that isn't much better than the “Which Harry Potter character are you” type quizzes your cousin loves to post on FaceBook.
When you cut the Jungian foundation off the MBTI what you're left with is a trait sorter. But there's a serious problem with this; the same trait can be caused by many different things. For example, many different shapes can cast the same shadow, but to know anything about the shape itself you need to know more than just the shadow. Knowing the volume and surface area will allow you to figure out the shape, with a little bit of work. In a similar way, knowing the functions and the function roles will give you the information you need to figure out your psychological “shape.” For this reason, even if you do decide to just take the test it's still necessary to confirm your results by making sure that the functions and roles of that type are actually your functions and roles.
The biggest problem with trait based tests, in my opinion, is that people of different levels of psychological health exhibit very different, even opposite, traits. For example, unhealthy INFPs can be unproductive, pessimistic complainers... but healthy INFPs are self-reliant, committed, dedicated, and effective forces for good. In other words, they start looking like their antipodal type, in their case a really chill ESTJ. So, this person who exhibits the traits of both a healthy INFP and a healthy ESTJ, are they an INFP? Or an ESTJ?
The only way you can really tell is by looking at the cognitive functions and the core complexes; no matter how healthy they are an INFP is always going to be confident about being in their INFP, and nervous about being in their ESTJ, and vice versa. Why is this even important though? Because the INFPs path to growth is completely different from every other type, even their sister type the ENFP; their weak spot is completely different, their area of hypocrisy that they need to work on is completely different, everything is different. Each type is unique.
So what's your type?
“Science, when it’s done the way it’s supposed to be, simply means learning about reality and changing it by investigating it, accumulating evidence by interacting with reality, identifying the patterns in reality, and then moving to change it on that basis. That’s all science is! Not something more mysterious or frightening.”- Bob Avakian [2]
When trying to figure out your own psychology it’s vital that you look at what you actually do, not what you think you is the “right” answer, or what you wish you were like. Everyone wants to think well of themselves! It's totally natural! It's really hard to have the level of self-awareness that's required; and even if you are totally honest, you can't know about things you don't know. There's going to be new stuff here, things you never thought about until someone else tells you. This is why it might be beneficial to have someone who knows you well (and will be honest with you) as a sounding board. It's almost always easier to see others clearly than it is to see yourself, you have less at stake.
The best way to type yourself and others, and to understand them when you do type them, is to have a solid Jungian foundation. This means the functions, the function roles, and the core complexes. Not only will you type yourself and others accurately, you will be able to take what you have learned and help yourself, and maybe even others, grow and develop. Once you come to understand your type, your strengths, your weaknesses, you will be able to figure out what it is that you need to do.
Jung always insisted that what he was doing was science. I'm not sure exactly what he meant by it, but to me this simply means; is it true or not? Is this something that actually exists? That's all that this process is; what are your observations? What's the pattern? Does the pattern hold when you test it? How can I apply this pattern to the world? What further things do I learn when I do so? What you are going to be doing here is exactly this. It's not something to be nervous about, it's just something we humans have been doing for as long as we've been human.
The process
Overview
- What's your house? Which attitude of each root function is in your consciousness? Ni or Ne? Ti or Te? Si or Se? Fi or Fe?
- What are your strongest and weakest functions? Which of the root functions (intuition, thinking, sensation, or feeling) are your strongest? Which two are your weakest? This will tell you which side of the house you're on (e.g. INFP/ENFP or ISTJ/ESTJ in Rowan).
- What type are you? After narrowing it down to two sister types, look at which cognitive function is in which function role.
- Confirm that this is actually your type.
What's your house?
The first step is to figure out which of the psychological functions are in your consciousness; this is what a house is, the types that share the same four conscious functions. For each pair of branch functions - Si/Se, Ni/Ne, Fi/Fe, and Ti/Te - one of them will be in your conscious and the other in your unconscious. Read the descriptions of the functions. Choose the ones that seem better, more correct, more accurate, more true; and which one seems off the mark, not really that important or just not as important as the other.
Some roles - the hero/ine and especially the anima/us - will be obvious. The mirroring nemesis and the daimon functions feel wrong, especially the nemesis. The daimon can feel wrong, or it can feel like it simply doesn't matter. The parent and the child, however, tend to be less clear than the hero/ine and anima/us, especially the parent. When looking at the parent and child functions it might be better to look the mirroring critic and trickster functions as they're generally more obvious. The critic and trickster functions are in one's unconscious however, so the other function is the one that's in your consciousness (e.g. if your critic is Ni and your trickster is Se, then the two conscious functions will be Ne and Si.)
Make sure the functions are in their proper function axes (plural of axis). Each branch function (Si, Te, etc.) is always connected with it's antipodal (opposite) function; opposite judging or perceiving, and opposite attitude. If you have introverted sensation, you must also have extroverted intuition. Intuition is the opposite perceiving function as sensation, and extroversion is the opposite attitude as introversion. The same holds for the two judging functions, feeling and thinking.
A useful way to think of the function axes is if the judging and perceiving functions were 2 seesaws. Let's use the perceiving axis as an example; if one side of the seesaw (sensation) is down then the other side (intuition) will be up, and vice versa. If one side is introverted then the other will be extroverted. The same holds for the judging functions (thinking and feeling). This will always be the case and is why you can use it as a test; is one side of the axis is introverted and the other extroverted?
If one half of the axis (Si) is in your consciousness then the opposite end (Ne) will be as well. The two ends are attached to each other. So if you don't have Si and Ne, if you have Si and Ni instead, then one of them is wrong and is actually in your unconscious. Same with the other axis. In that case go back and look at the functions again. If you're still unsure just pick the one that seems best and continue on but keep the other function in mind. When you get to the stage of looking at the function roles, see which one fits better. Examining the functions in their roles will confirm (or not) your choice.
These are the four function axes:
Once you have your functions and function axes you know your house. Read the description of the house. Does this sound like you? Note any feelings that come up, whether of affirmation or rejection and what specifically it is that you're affirming or rejecting. If you need to go back because you were unable to confirm your type this will give you an idea of what to look for. And even if you get your type right the first time, knowing these things about yourself will help you better understand yourself, and what direction you may need to look when working on yourself.

| Function axes and houses |
The cognitive functions
The houses
House Ash
House Yew
House Oak
House Rowan
Example: Mr. X
Next he turns to the two other functions, sensation and intuition. He's not so sure of them. He cares about looking nice and having a pleasant physical environment (Se) and about being conscientious and careful (Si). Same with intuition; he actually has a fun-loving side (Ne) though few people would believe it. And he thinks he knows what he wants (Ni). Everyone knows what they want, right??
Since he's stuck, he thinks about which of the four functions could be his critic; where is he the harshest and most judgmental? He looks over the descriptions of the four branch functions and decides that it's probably Se; there's nothing he hates more than seeing someone wearing sloppy, dirty clothing, or obviously not taking care of themselves. He takes the time needed to make sure he looks professional and presentable, why can't everyone else???? People should stop being so lazy!! So Se is probably his critic function. That means that Ni should be his trickster. He thinks back; he does have a really hard time making up his mind about things he wants, something his close friends have teased him about on more than one occasion. He decides that this seems right to him.
Since his critic is Se and his trickster is Ni, two roles that are in his unconscious, their mirror opposites, Si and Ne, should be in his conscious. As he's already decided that Te and Fi are in his conscious that means that his house is Rowan (Te/Fi and Si/Ne axes).
What are your strongest and weakest functions?
Which two root functions (sensation or intuition? thinking or feeling?) are you strong at, and which two are you weak at? You will have one strong judging function, and one weaker one, the same for perceiving. The weaker two functions are generally very easy - glaringly easy - to spot. Especially the inferior anima/us function, which is always painful and intimidating even when integrated. The child function is weak but you don't really care, but the anima/us function is our place of shame and deep pain. It's pretty hard to miss.
Doing this will tell you which “side” of the house you're on. Each house has a split where two types are good at the same two functions, and the other two are good at the other two functions. In House Ash, for instance, the split is between sensation/feeling (ESFJ and ISFJ) and intuition/thinking (ENTP and INTP). In the example from earlier ("is the person in question an INFP or an ESTJ?"), this will tell you which one you are since the two types are on opposite ends of House Rowan. If you have absolutely no idea, though, it will at least narrow it down to the two sister types (e.g. INFP/ENFP). Below are the splits within each of the houses:
Ash
Sensation/Feeling is ISFJ & ESFJ
Intuition/Thinking is ENTP & INTP
Oak
Sensation/Feeling is ESFP & ISFP
Intuition/Thinking is INTJ & ENTJ
Yew
Sensation/Thinking is ESTP & ISTP
Intuition/Feeling is INFJ & ENFJ
Rowan
Sensation/Thinking is ISTJ & ESTJ
Intuition/Feeling is ENFP & INFP
This will also help with any confusion you may have had in the previous step; if you're not really sure which branch function is your parent and which is your child, the parent will be one of the two stronger functions and the child will be one of the two weaker functions.
Example: Mr. X
Mr. X looks at the four root functions; sensation, intuition, feeling, and thinking. He knows that he's confident in his thinking, and that he's extremely lacking in confidence in his feeling. Of the two perceiving functions, he decides that, while he really enjoys his little adventures traveling the world and driving his muscle cars (Ne), he's actually much better at being careful, thoughtful, and contentious (Si), though he sometimes pays less attention to this part of life than he probably should. He has a tendency to charge ahead without taking the time necessary to think things through carefully. But he feels more confident in this area of his life, so his stronger functions are probably thinking and sensation, and his weaker ones are intuition and feeling. This means he's either an ESTJ or an ISTJ.
What type are you?
After narrowing it down to two sister types, compare the roles of the functions for the types. The easiest ones to spot are the anima/us and trickster; it's very hard to hide those. After those two roles the heroine, nemesis, critic, child, parent, and daimon are the easiest to figure out, in approximately this order. All you really need are two or three function roles, once you have them you can figure where everything else falls, but the rest of the roles should corroborate your type.
In the example of INFP/ENFP, an INFP will have Te animus and Se trickster, while ENFPs have Si animus and Ti trickster. This means that if you really worry that you are ineffective and will die without having done anything good or important, and you tend to struggle with physical reality (tripping, running into things, stuff like that) you're probably an INFP. But if you struggle with the everyday grind - the boring, daily drudgery - and you worry that you're kind of dumb, or others have told you that you're a real airhead, you're probably an ENFP (this isn't to say that ENFPs are dumb, far from it, but that they don't have logic in their thinking, it's aaaalll about effectiveness; in other words, “truth is just a concept, everyone has their own 'truth,' what matters is whether or not you get stuff done.”) The child function can also be very useful; do you really enjoy farting around, doing a whole lotta nothing? You probably have Si child, making you an INFP. Or do you prefer to be active, specifically do you really enjoy organizing things, and maximizing efficiency (Te)? In that case, you're probably an ENFP.

| MBTI types and functions |
This is the stage where, if we struggled to figure out our conscious functions in the first step, we confirm or reject our choices in that step. The parent in particular can be a bit of a challenge as its often the function that we actively run away from having to use. This is a sign of psychological immaturity; many, probably most, people try to do an “end run around” the uncomfortable parent function. However, we usually glory in wielding our critic function, beating others over the head with it like a cudgel. The difficulty comes from differentiating the critic from the parent. In my experience, the parent & critic, more than the other three relationships (hero/ine & nemesis, child & trickster, and anima/us & daimon), appear to be fused. In all four relationships the unconscious role seems to act through the conscious role, but none more so than the critic.
If you're still struggling another option is to triangulate the parent by looking at the critic, child, and trickster functions, which are usually much more obvious. The trickster is one of the first functions you want to look at. If you think you know which one is the trickster, look at it's mirror function (Se if your trickster is Si, Te if your trickster is Ti, etc.) Does this sound like the child to you? Do you feel that it's something you're not that good at but you really enjoy doing, especially when you want to relax and feel good? In the posts linked to below, “The function roles” are descriptions of the roles, while the post “Functions + roles” are brief sketches of each cognitive function in the 8 different roles.
One very important thing to keep in mind: just because you think something is important doesn't make it your dominant (hero/ine) function. I think being a good person, and kind to others, is the most important thing in the world but that doesn't make me an Fe type. What it means is that I've integrated my Fe animus function. A similar thing happens with the parent function sometimes; when I was first trying to figure out my own type I wasn't sure if if my heroine was thinking or intuition. I knew that they were my two strongest functions, and that sensation and feeling were my two weakest, but not which one was which. The clincher was the animus; while I knew I was bad at sensation and was kind of embarrassed sometimes I was absolutely terrified of making a social faux pas, and absolutely devastated when I invariably did so.
As we move around the circle of our personality we integrate the functions, and as we integrate the various functions we live that function with all it's strengths and weaknesses. As we move into each of the complexes we think and feel like the type of that complex. But this doesn't change our fundamental personality; our strengths and weaknesses, our areas of hypocrisy, where we love to nurture and where we want to be nurtured. It doesn't change our spiritual task. In order for us to fulfill our purposes as human beings - to bloom into the astonishing, unique flower that we were meant to be - we need to know what our actual path is.
Functions + roles
Integrating the four functions
Mr. X already thinks he knows his type - ESTJ - because it's pretty clear to him that of his two strongest functions, Te and Si, Te is the strongest. He knows this because of how easy it was for him to identify Te and Fi as his hero and anima functions; Fi is definitely his anima function, he has no doubt. And the description of Te describes him... to a "T" (lol). This would naturally make him either an ESTJ or an ENTJ, the two types that have dominant Te. He's in House Rowan, though, so that should make him an ESTJ. He needs to look at the rest of the functions in their roles to confirm this.
He reads over the descriptions of the functions + roles: parent Si, child Ne, nemesis Ti, critic Se, trickster Ni, and daimon Fe. The critic, nemesis, and trickster functions ring true for him. He's not so sure about the daimon though but that's not surprising as it's very hard role to see in ourselves. That fact in and of itself validates putting Fe in the daimon role. The type that has Te hero, Fi anima, Si parent, and Ne child is ESTJ. Now he needs to confirm that that's actually his type (step 4, the next step). He reads the description of his type, including the core complexes of his sodality. After reading this he decides that his choice is correct, he is an ESTJ.
Go and read the description of the type. Look at the core complexes for the type; one thing to remember with types is that we can “live” in any of our core complexes. You can have a very INFP INFP, or you can have an INFP who lives in their ESTJ a lot. They still have their core INFP ego but they are extremely practical and concerned with security. This is actually a quite common. In fact, I'd say that most people of average or even low-average psychological maturity usually integrate their P2 anima/us complex by mid-life, sometimes even earlier. If someone lives in a core complex other than their P1 ego this will make it more difficult to type them simply based on their personality traits. This is why it's so important to look at the functions.
So look at the functions and the core complexes for the type you think you are. Does this sound like you? Do other people think this sounds like you? If it doesn't go back and see where you might have gone wrong. Even when you get things wrong, though, it's not a waste. If you're atypical of your type, why might that be? Is there something you need to work on? Or is this showing an area of health in your psyche? Every piece of information is valuable, everything tells you something. If it does sound like you... CONGRATULATIONS! You can now get to work. 😀
The core complexes
One final thing: the MBTI's four letter code
I wasn't sure where to put this, but this post seems the most logical. What do the four letter of the MBTI types mean? This is actually something that I didn't understand for years, lol. It seems pretty obvious; the first letter is whether the person is introverted or extroverted. The second letter is whether sensation or intuition are stronger. The third letter tells you whether thinking or feeling are stronger (remember two of the root functions will be stronger - one judging and one perceiving - and the other two will be weaker.) It's the last one that's confusing, the J or the P. What does “being a judger or perceiver” actually mean?
But what makes a “J-type” a J? Or a P-type a P? For example, ISTP's have introverted thinking - a judging function - as their dominant function. Why aren't they ISTJs?? Same with ISTJs, their dominant function is a perceiving function, introverted sensation. In fact, it's the same for all introverted types; if a type is introverted the P or J at the end of their type doesn't refer to their dominant function. What's going on here???
E: Dominant extroversion
ST: Their dominant perceiving function is sensation, dominant judging is thinking
P: Of the two dominant functions - sensation and thinking - sensation, the perceiving function,
is extroverted
So, in an ESTP extroverted sensation is the dominant (hero/ine); introverted thinking is the secondary function (parent); the tertiary function is the opposite judging function, feeling (the child); and the last function, opposite the hero/ine, is introverted intuition (anima/us).
E: Dominant extroversion
ST: Their dominant perceiving function is sensation, dominant judging is thinking
J: Of the two dominant functions - sensation and thinking - thinking, the judging function,
is extroverted
In an ESTJ extroverted thinking, the judging function, is the dominant (hero/ine); introverted sensation is the secondary function (parent); the tertiary function is intuition (the child), and the last function is introverted feeling (anima/us).
As you can see extroverted types are pretty straightforward. The problem is the introverted types. The thing you have to remember is that the final letter doesn't refer to the the hero/ine function. The final letter indicates which of the two dominant functions is extroverted. Let's take a look at the ESTPs sister type, the ISTP.
I: Dominant introversion
ST: Their dominant perceiving function is sensation, dominant judging is thinking... just like the
ESTP
P: Of the two dominant functions - sensation and thinking - sensation, the perceiving function,
is extroverted... also just like the ESTP
As you can see, the ISTP is very similar to ESTP; both have dominant extroverted sensation and introverted thinking. But which of the two functions is the hero/ine? The introverted function; (“I.”) That means that introverted thinking is the dominant (hero/ine); extroverted sensation is the secondary function (parent); the tertiary function is intuition (the child), and the last function is extroverted feeling (anima/us).
An introverted person is different; with them, you never directly meet the captain. The captain, the dominant heroine function, is introverted. Therefore, whenever she needs to interact with the passengers she always sends out her first mate to run interference for her. In the ISTP this would also be extroverted sensation. However, Se is the ISTP's secondary function, their parent function. It's not really who they are, it's not their ego. When you interact with an introvert you aren't seeing who the person actually is as their hero/ine function is turned inwards. This can make introverted types seem a bit more awkward than extroverted types as what you're really dealing with is their second strongest function.
This is the reasoning behind the MBTI's naming convention. Although its confusing initially it's actually a more accurate way of referring to the types as it clearly shows the connection between the sister types (ESTP/ISTP, ESTJ/ISTJ, etc.) The two are very similar and can look very similar to an outside observer, especially if they've done some maturing and have integrated their parent function.
Antonia Dodge, “What is a 'Judger,' and What is a 'Perceiver?'” (Personality Hacker)
John Betts, “Type1,” “Type2,” and “Type3” (The Jung Podcast, episodes 11, 12, & 13)
John gives the metaphor of the hero/ine as a captain in “Type3” (ep. 13)
So now you should know your type! Figuring out one's type is often a long, complex process, with many challenges. However, as it's crucial to get your type right it's a necessary and worthwhile endeavor. The absolute best way is to study the fundamentals of the theory, fundamentals that come from some really brilliant, deep thinkers, like John Beebe and CG Jung. In fact, the process of figuring out one's type is itself one of the very best ways to learn the MBTI.
Allow this to be an amazing learning experience, one where you not only explore this fascinating, important area of the human mind and soul, but also to learn about yourself, as well as those who are important to you. Let this be something that makes you a better, more complete person.
