Jungian Function Reference Sheet!
The Jungian Functions had always been the hardest part of the whole MBTI psychology system for me to understand when I was first learning about it, so I made a simplistic little sheet to help other people make sense of it and the differences between Introverted and Extroverted functions.
Before you read the rest, I would suggest that if you don’t know much (or anything!) about the Jungian Functions part of MBTI, you should do some research! It’s really interesting and a lot more in-depth in terms of psychology and personality stuff in general. You don’t have to, but the rest of this will be absolute nonsense to you so? I don’t know why you would read it?
To the rest of you, I hope this is helpful!
INTUITION (Ne v Ni)
The Intuition function is what controls your ability to find patterns and connections. If you have strong Intuition (your Primary or Secondary function), you enjoy or are talented at working with abstract theories and ideas, and your memories will come often as general impressions of your emotions or sensory details rather than specific facts.
Introverted Intuition (Ni)
Introverted Intuition is fairly uncommon when it comes as a Primary or Secondary function. Only about 1 in every 12 people you meet will use Ni in such a way that it is obvious in their everyday life. The people who have a Ni primary are INTJs and INFJs, with ENTJs and ENFJs following behind with Ni as their secondary.
People with Ni are very trusting of sudden gut feelings. These feelings may be hard to explain because they are often more abstract ideas that fit with their values and morals than tangible facts.
They’re very good at finding patterns and making connections between things that may not seem to share similarities. Once they’ve found a connection or had an idea, Ni dominants feel the need to develop or put the idea into action.
Extroverted Intuition (Ne)
Extroverted Intuition is much more common. 1 out of every 5 people you meet will use Ne as one of their primary or secondary functions. The people that use Ne as a primary function are ENFPs and ENTPs, and following up with a Ne secondary are INTPs and INFPs.
Ne users also trust their gut impulses, but they find their impulses easier to explain because they are more adept at finding hidden messages and meanings. They are able to get multiple meanings from one idea and juggle different theories well. Eventually, using those multiple theories, they are able to piece together a common thread.
Ne users enjoy brainstorming and trust the results, and often turn out to have major roles in the arts, becoming authors, artists, inventors, and even philosophers.
Summary:
The Ni users, SPs and NJs, like making connections and following through on them.
The Ne users, SJs and NFs, like finding hidden messages and creating a common idea that string them together.
THINKING (Te v Ti)
The Thinking function directly relates to how you receive, process, and use information. The type’s preference for Extroversion or Introversion controls how they use the Thinking function in decisions. If you have strong Thinking, you enjoy or are talented at analyzing and processing data.
Introverted Thinking (Ti)
Introverted Thinking is possessed in a noticeable way by 1 out of every 5 people, or 16%, but 46% of people have this function. The people who have Ti as their Primary function are INTPs and ISTPs. ENTPs and ESTPs use it as their secondary.
Ti users like consistency in their logic and ideas and often form a kind of internal barrier that they run all new ideas and concepts through. Because of it’s abstract system, it may be hard for them to explain to other people, and may even be hard for them to understand themselves. Ti users are skilled at finding just the right word, which in turn makes them adept at conversation as well.
Ti users are known to break things down to get a better sense of how it works, often looking for inconsistencies and seeing all sides of an issue or idea. This applies not just to how they approach intellectual situations, but also emotional ones, and enjoy diving into their own and other’s motivations and pysche. They often end up to be scientists and philosophers.
Extroverted Thinking (Te)
Te users, including the primary users ENTJs and ESTJs and secondary INTJs and ISTJs, make up 54% of the population.
Te users also like logic and consistency, but they look for it in the external world, creating concerns and focuses on laws and rules. They are natural planners and organizers, often creating many different plans for one circumstance. They are constantly and unhaltingly logical, never pausing to correct someone’s mistake by providing evidence and hard facts.
Te users have remarkable abilities of organization, and are able to focus and do what needs to be completed because they are able to set other aspects aside while they do. They are often leaders and managers.
Summary:
The Ti users, xNTPs and xSTPs, like finding inconsistencies in their everyday life and personal relationships.
The Te users, xNTJs and xSTJs, like creating, and then following through, on rules and plans.
FEELING (Fe v Fi)
The Feeling function relates to how you use or value your emotions when making decisions. If you have strong Feeling, you use your emotions very often, and maybe rely on them completely, when making important decisions.
Introverted Feeling (Fi)
Fi users make up 54% of the population. Primary Fi users are the INFPs and the ISFPs, and ENFPs and ESFPs use it as a secondary.
Fi users have very strong morals and beliefs, and rarely speak in ways that conflict with these internal laws. Introverted Feeling also helps the user to understand people’s true intentions. Fi users value honesty, both to themselves and others, and they would rather people be their true selves then change themselves to bond with them.
As Fi users have the ability to discern between very subtle differences, they often become authors, philosophers, singers, and actors.
Extroverted Feeling (Fe)
Fe users make up 46% of the population. Primary Fe users are ENFJs and ESFJs, and secondary users are INFJs and ISFJs.
Fe users value harmony over honesty, unlike the Fi users, and are willing to set their own opinions, needs, and values aside for the sake of getting along. They have strong desires to get along, and are often seen as friendly and warm people, and their emotions are often written all over their face.
Fe users also, purposefully or not, read people’s personalities and change their mood or tone, and even sometimes their opinions, to mirror the other person or people’s. They’re often found to be teachers or teacher types, like talk show hosts or activists.
Summary:
The Fi users, xNFPs and xSFPs, try their best to encourage originality and honesty, and are willing to look selfish or strange to be their true selves.
The Fe users, xNFJs and xSFJs, try their best to create harmony and are willing to put their values aside to do so.
SENSING (Se v Si)
Sensing is one of the ways you take in information, and if you possess strong sensing, you prefer information to be taken in through their senses. It also means you will tend to be more focused on current circumstances than you are with future possibilities and ideas.
Introverted Sensing (Si)
Si users make up 65% of the population, or about 2 out of 3 people. ISFJs and ISTJs are the two primary users of Si. Secondary users are ESFJs and ESTJs.
Si users compare present facts to their past experiences, and trust their past, using it as a guideline for new situations. Si users are very detail-focused, and have strong skills in using past experiences to make decisions in the present.
Si users are often very detail-oriented, needing to clarify goals and objectives to make them happen. They love tradition (sometimes to a fault) and are often political leaders, military commanders, and other tradition-honoring careers.
Extroverted Sensing (Se)
Se users make up 35% of the population, or 1 out of 3 people. ESFPs and ESTPs are the primary users of Se, with ISFPs and ISTPs using it as their secondary function.
Se users follow their instincts to make their move when it is needed, because they are deeply in tune with their situation’s sensory cues. They act on what is happening in the moment without drawing on past experiences. They are able to isolate relevant data from the world around them and don’t hold on to their ideas of the past or future for long.
Se users are likely to become athletes, actors, and pop stars, to name a few, because of how aware they are of the world around them in it’s entirety.
Summary:
The Si users, xSFJs and xSTJs, are detail-oriented and rely heavily on their past experiences to guide them.
The Se users, xSFPs and xSTPs, are impulsive and are able to pick out what they need and use it to their advantages.
I really hope this clears things up a little bit for all of you that are concerned! I might make a little strengths/weaknesses of the Functions soon too, but I’ll have to wait and see the feedback I get for this one first <3 Hope it helped!
