Every personality type has something incredibly valuable to offer the world. Each comes with a slightly different way of learning new information, seeing the world, making decisions, and interacting with others. And that means that we each have the potential to positively impact the world in different ways.
For this list, I’ve paired the types that use the same primary and co-pilot functions together. For example, both ESFJ and ISFJ use Extroverted Feeling and Introverted Sensing as their preferred functions, just in a different order. If you’re new to Myers-Briggs® theory or want a quick refresher, you can click here for a quick intro to how functions work.
ESFJ and ISFJ
ESFJs and ISFJs change the world by connecting with and supporting other people, as well as preserving and passing on valuable lessons of the past.
Having Extroverted Feeling as either their primary or co-pilot function gives SFJ types a strong desire to help and support other people. They tend to personalize everything they do and care so deeply about others that they may forget their own needs while selflessly serving those around them. They’re also really good at picking up on what other people are feeling.
With Introverted Sensing as either their primary or co-pilot function, SFJs have a strong desire to learn from the past. It’s the function that helps us make sure we remember what was learned in our personal and collective histories so we don’t keep repeating failures as we go forward.
ENFJ and INFJ
ENFJs and INFJs change the world by bridging gaps between people who have different perspectives and offering a vision for what the future could look like on both personal and societal levels.Read more →
What fictional characters do you relate to as an INTP?
Just as we can describe real people using the Myers-Briggs® typology system, we can also use the system to type well-written fictional characters. Some of fiction’s most iconic and intriguing characters are INTPs, and today we’re going to talk about seven of them that I think real-life INTPs will find relatable.
One great thing about looking at character personality types is that it helps us to better understand people who have different types than we do. Fictional INTPs can serve as examples for what real-life INTPs might be like, and also show how much variation can exist between individuals with the same type.
I actually typed Alice as an ENTP on my Disney Princess MBTI chart, but many people type her as an INTP. I’m fairly certain she uses Introverted Thinking and Extroverted Intuition as her two favorite functions, so both ENTPs and INTPs will probably find her a relatable character.
Extroverted Intuition is the most visible aspect of her personality. “If I had a world of my own everything would be nonsense,” seems the sort of thing a bored, curious intuitive would say as they try to explore every possibility no matter now far-fetched. As Alice goes through Wonderland, she’s constantly testing the different aspects of the world and asking questions. Read more →
One of the most influential names in personality theories surrounding Myers-Briggs® types is David Keirsey. His book Please Understand Me II was one of the first I read when I decided to study personality theory because it was so widely recommended.
The more I studied Myers-Briggs types, though, the less comfortable I felt with Keirsey’s version and the more questions I had. Was his insistence on grouping the 16 types into 4 categories really all that useful? Is the practice of giving each type nicknames doing more harm than good? Why did he seem to ignore Jungian psychological functions? I started to think maybe he’s not the best resource for studying Myers-Briggs, though he does offer an interesting perspective on how the 16 types might relate to historic 4 type systems.
I’ve debated quite a bit whether or not to actually write this post. But I’ve been reading Personality Type: An Owner’s Manual by Lenore Thomson, who is a former managing editor of the Junginan journal Quadrant and who has taught courses on psychological types at the C.G. Jung Foundation in New York City. In her discussion of the ITP and IFP types, she voiced some of the same frustrations with Keirsey that I’ve felt, particularly in regard to how he talks about the SP types.

Keirsey’s Focus on SP Types
I do want to start out by saying that I know Keirsey’s intentions were good in how he described SP types. He saw himself as “championing” the SPs (who he called “Artisans”) more than any other type because his parents, brothers, and many of his friends were Artisans. In addition, much of his work for 30 years as a family therapist was spent working with Artisan children who gave their parents and schools a hard time when they were noisy and restless or didn’t finish assignments.
My long association with and understanding of Artisans of all ages has enabled me to be more useful to them than to others of different temperament. I think Artisans ought to be enjoyed for what they are instead of condemned for what they are not, something that can also be said of the other three temperaments. (Keirsey, Please Understand Me II, p. 33)
While I agree with the sentiment, I think that some of Kersey’s theories did a disservice to SP types by constraining them into an art-making, hedonistic stereotype. There’s so much more to them than that, and I think by simply focusing on their shared SP traits we lose a lot of the nuances of each of these four type. I doubt this was his intention, but that’s how people seem to have used/misapplied his theories. Read more →
In the Myers-Briggs® typology system, a preference for Feeling (F) or Thinking (T) shows up as the third letter in your personality type. But what does it actually mean to use Thinking over Feeling, or vice versa?
You’ve probably heard that Thinking types tend to be more rational and cerebral than Feeling types, who are typically more emotional. There’s a lot more to it than that, though, and the stereotype isn’t entirely accurate. Keep reading to learn 5 things you might not have known about the Thinking and Feeling processes.
They’re Both Judging Functions
Thinking and Feeling are both what we call “Judging” functions. They’re used to describe the psychological process you use most often when making decisions. If you have an F in your four-letter type code, then you use Feeling to make decisions. If you have a T in your type, then you use Thinking.
If you’re a Judging (J) type, then that means you use your judging function to interact with the outer world. A TJ type uses Extroverted Thinking and an FJ type uses Extroverted Feeling as their most comfortable way of making decisions. If you’re a Perceiving (P) type you still have a judging function, but it’s oriented to your inner world. A TP type uses Introverted Thinking and an FP type uses Introverted Feeling.
A few weeks ago a fellow INFJ named Bo Miller contacted me and asked if he could interview me on his new podcast. After picking my jaw up off the floor and texting my boyfriend to share that I was equal parts terrified and excited, Bo and I started a conversation that led to this interview. Our conversation focused on how INFJs can understand and learn to use their Extroverted Feeling and Introverted Thinking functions.
I already shared this link on my Facebook page, but in addition to the podcast I have a special treat for you all today as well. Bo is a Certified Myers-Briggs practitioner and the creator of iSpeakPeople.com as well as The INFJ Personality Show. He recently published The INFJ Personality Guide and would love to give you a free copy. I haven’t read it yet myself, but from my conversations with him I’m pretty well convinced it’s going to be really good. I hope you’ll grab a copy and check out his website. Here’s more info:
In The INFJ Personality guide, you’ll discover…
• Your greatest strengths
• Your weaknesses
• Why the rest of the world thinks differently than you

• How to develop your personality and reach your potential
Because INFJs and INTJs both use Introverted Intuition as their favorite mental process, the two types can appear very similar. Quite a few people who take a Myers-Briggs test and get either of these results (or both on different tests) are left wondering, how can I tell whether I’m an INFJ and INTJ?
My personality type is INFJ and my sister’s is INTJ. It would be well-nigh impossible to assume we share a personality type, but if you don’t have that contrast living with you (or if you’re a little less extreme on your T/F preference) I can see how deciding which type is your best fit could be a challenge. INFJs and INTJs lead with the same mental process and they react in very similar ways when stressed out. The main differences between the two types have to do with how they handle their Thinking/Feeling preference.
INFJs use auxiliary Extroverted Feeling as their copilot and support it with tertiary Introverted Thinking. INTJs use auxiliary Extroverted Thinking as their copilot and support it with tertiary Introverted Feeling. The auxiliary process is how they prefer to make decisions and interact with the outer world, but they can slip into their tertiary quite easily. It’s not as well developed or as reliable, but it can seem comfortable since it’s introverted (just like their dominant intuitive function).
How comfortable each INFJ/INTJ is with their thinking and feeling processes depends on a number of factors, including age, environment, and past experiences. You can find INFJs who are very people-oriented and social, or INFJs that seem distant and logical. Similarly, you’ll meet INTJs who are stereotypically blunt and calculating, and INTJs who are comfortable experiencing their own emotions. Even so, the way these functions shows up looks different for each type.
My Cup of T
An INTJ’s Thinking side is focused on the outer world. It’s also the function they’re most comfortable using when making decisions. While mature, well-balanced INTJs will take the human side of a question into consideration, it’s typically secondary to finding the most logical, fact-based solution. Personality Hacker calls this mental process “Effectiveness” and says it “focuses on impersonal criteria for making decisions” and prioritizes efficient problem solving.
INFJs, on the other hand, use an inward-focused Thinking process and they’re not usually as comfortable with it as they are with their Feeling side. Personality Hacker calls Introverted Thinking “Accuracy” and says this function gives users “the ability to reason through a subject or concept within one own’s understanding, even if it doesn’t match ‘outer world’ data.” Basically, this process is trying to work through things until they make sense.
INTJs are much more likely to express their Thinking judgements externally than an INFJ. They’ll often seem more blunt and direct because efficient communication is more important to them than worrying another person’s feelings. INTJs are also more likely to draw on objective, external facts to support their ideas. They want their ideas to work and they want outer world validation for their problem solving. That’s not nearly as important to INFJs, who need things to make sense personally more than to the people around them.
Feeling The Feels
An INFJ’s Feeling side, like INTJ Thinking, is the function they use most comfortably when making decisions. It’s also outward focused, but it’s primarily people-oriented. Personality Hacker nicknames this function “Harmony” because it “makes decisions based on how things are impacting people on an emotional level.” The key thing to remember about this function is that it’s outward focused. INFJs are more in touch with other people’s feelings than they are their own.
INTJs use a Feeling process that’s introverted, which Personality Hacker calls “Authenticity.” While it’s also concerned with how decisions impact on an emotional level, it’s focused on one’s own emotions rather than other people’s. To again quote Personality Hacker, “Introverted Feeling is about checking in with all those inner parts and voices to determine what feels the most in alignment with oneself.” Somewhat ironically, the stereotypically cold and logical INTJs are often much more in-tune with their own feelings than the stereotypically emotional INFJs.
INFJs are more comfortable expressing feelings in the outer world and also more likely to pick-up on what other people are feeling. They’ll typically seem much more empathic and expressive than an INTJ. An INFJ who’s comfortable with their Extroverted Feeling side will also appear more social and “extroverted” than a typical INTJ. But INTJs are far more in-tune with their own emotions than most people (and many type descriptions) will give them credit for.
INxJs In Real Life
Even after you know about the technical differences between the ways INFJs and INTJs use thinking and feeling, you might still wonder they show up in real life. Let me give you some quick examples.
When making an everyday decision — an INFJ’s first impulse will be finding what makes as many people as possible happy, while an INTJ’s first impulse will be quickly finding the most logical answer. For me and my sister at least, the INTJ has a much easier time making simple decisions without overthinking them than the INFJ does.
In a stressful/emergency situation — I’m the one who’s in logic mode and my INTJ sister is the one indecisive and unsure. We’re talking something that calls for quick action and is stressful enough to push you out of your most comfortable mental processes (such as deciding to take someone to the hospital), Might not hold true for every INFJ or INTJ, but it’s an interesting observation I’ve made.
If asked to change their minds — an INTJ is most likely going to stick with what they’ve already decided because they know their idea is based on logic and that it feels right to them. To change their mind, you’ll need to present a fact-based counterargument that matches their deeply held beliefs about what’s right. A confronted INFJ will second-guess themselves because now they know someone isn’t happy with what they chose but they’ll also be reluctant to abandon something that makes sense to them. To change their mind, you’ll need to present an argument that hits emotion as well as logic.
I hope this helps you with telling the difference between these two types If you can’t tell if you’re an INFJ or and INTJ, looking at the differences in Thinking and Feeling functions is a good place to start figuring out your type. You’re not going to be a perfect 100% fit for every description of any one personality type, but there should be one that’s a “best fit” for your personality.
