Understanding the 16 personalities in MBTI is a valuable tool that can offer you deep insights into yourself and others. The Myers-Briggs Type Indicator (MBTI) framework categorizes individuals into four key dimensions: Extraversion (E), Sensing (S), Thinking (T), Feeling (F), and Judging (J) or Perceiving (P). This knowledge is essential for self-awareness, understanding strengths, weaknesses, and natural inclinations. It helps us to make choices that align with our personality & optimize for personal growth.
Furthermore, knowing the 16 personalities & the 8 cognitive functions themselves, also allows for appreciation of diversity and understanding others on a deeper level. By recognizing people’s preferences & perspectives, individuals can develop greater empathy and compassion towards those who approach and interact with the world differently. This enhances communication, conflict resolution, and building harmonious relationships with friends, family, coworkers, and romantic partners.
In this article we will cover some of the basics as far as history, MBTI dichotomies (categorization), and a brief overview of each of the types. If you want to learn more about any of these types, be sure to bookmark this site as we will be deep diving into more specific topics such as comparisons, compatibilities & type-specific advice.
History Of The Theory
Carl Jung, a Swiss psychiatrist, developed theories on personality, including concepts like introversion and extraversion. His work emphasized individual differences and the integration of the conscious and unconscious aspects of the psyche. Katharine Briggs and Isabel Myers were inspired by Jung’s ideas and created the Myers-Briggs Type Indicator (MBTI), a psychometric tool that categorizes individuals into 16 personalities based on preferences in four dichotomies: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving. The MBTI helps individuals gain insights into their strengths, weaknesses, communication styles, and decision-making approaches.
The MBTI has been widely used for personal development, career counseling, and relationship counseling, among other applications. While it has faced criticism & rightly so, it remains a popular framework for understanding and appreciating individual differences in personality, building on Jung’s original theories and providing practical tools for self-discovery and understanding others.
The 8 Cognitive Functions Categorized
While most sources will teach the 4 dichotomies, we believe they can introduce unneeded confusion into the system. This is especially true when it comes to judging, perceiving, and what connotes extraversion & introversion.
Below is a much more simple & accurate approach that’s based on the individual functions & positions in the function stack – not on the 4 letter personality type. The drawback of the traditional MBTI way being that the lack of functions does not offer a deeper explanation to the inner works or the WHY. It tends to over-simplify the types & reads more like a horoscope.
The 8 function model on the other hand, breaks down the individual personality type into 8 facets which are much more observable, accurate, and allow for more nuance. This is akin to studying the inner machinations of what makes a person tick, why we do what we do, and what our natural inclinations are.
Intuition
Intuition essentially relates to a person’s inclinations towards conceptual thinking. This can take the form of pattern recognition, predictive abilities (cause & effect/consequences), planning, and is overall a future-based perceiving function. Perceiving meaning that it’s how we take in or observe the world conceptually as opposed to in a 5-senses type of way.
Introverted Intuition, also known as “Ni”, is all about a person’s own desires for themselves & their own future. It can come off as “wanty” or driven to attain their vision. Those who have Ni in their function stacks require choices & personal freedom is a value their hold in high regard.
Extroverted Intuition or “Ne” on the other hand, is less focused on a single vision & more “go with the flow”. We associate this function heavily with archetype or trope awareness, metaphysics, the collective unconscious (the interconnectedness of it all), and creativity on all levels. It’s also linked to a person’s predictive ability & often finds itself warning the Ni user of possible consequences.
Sensory
While intuition can get overly theoretical, future focused, or “”woo-woo”, the sensory functions are opposite. Sensory functions are more matter of fact & concerned with what is & what was as a form of perception or observation.
Introverted sensing or “Si”, is a function that overlaps many facets of life. Some of the primary concerns of Si are: loyalty, endurance, duty, discipline, comfort, stability, and memories.
Depending on how high the function is in an individuals stack, different types will require more comfort or be able to sustain discomfort for longer durations. Similarly, unwavering discipline can be developed in types with this function.
Si is considered slow and patient, and can be represented through the fable “Tortoise & The Hare“. Most importantly, Si is all about a person’s own personal experience through the 5 senses & their recollection of the past via memories.
Extroverted Sensing aka “Se” is the opposite. It’s not so concerned with the past, as much as the present moment. It’s about quick reflexes, courage, affecting change in the physical world and taking action now! Se is also awareness of physics & is highly valued in fields such as sports, engineering, & hobbies that are based on performance. Se users are highly attuned of the experience they are giving to others and for the most part seek attention, however, it’s the Si user who decides to give them that attention.
Thinking
The past 4 cognitive functions were all about gathering perceptions or observing the world as an individual. These next 4 however, are more related with decision making, either through a logical framework or through value-based decisions.
Introverted Thinking types, those with “Ti”, are traditionally labeled as smart or “geniuses” in the academic sense. This function allows for someone to go many layers deep on a single topic to process information, find workable solutions, and discern the facts for themselves. It’s the function for deep thinkers, those with original thoughts, and those considered to be thought leaders.
Extroverted Thinking or “Te”, is the anti-thesis of Ti. It’s much less concerned with its own conclusions & draws facts from the collective via statistics, common sense, and best practices. Those with this function are geared towards rational thinking that’s quick & has breadth, although it can lack in its depth. One final distinction is that Te users tend to lean more towards achievement & success, while the Ti user is more concerned with being accurate & being the smartest person in the room.
In terms of decision making, the Ti user will use their own facts & logical findings to decide on a proper course of action. This is why it’s considered a “source” or “introverted” function. Te users however, are more extroverted in the sense that they make their decision based on outside sources, for example, when using statistical data or referencing authorities on the topic.
Feeling
Finally, we have “Feeling” which is the second set of decision making functions. To a thinker, these might seem like an irrational way of going about practical problems and choosing the best path forward. However feeling functions are based on personal morals (Fi) or group ethics (Fe).
Introverted Feeling aka “Fi” is tied to conscientiousness or doing the right thing when no-one is looking. People with Fi are more aware of their own personal feelings on a matter and what they consider to be good or bad. When used in decision making they will use their own personal value structure to weigh the choices. Furthermore, because it’s an introverted function, it can come off as a bit selfish because it will not weigh in the opinions of others on the matter. That’s not necessarily a bad thing, but something to be aware of.
It’s also important to note that Fi, as well as Ti, are both “identity functions” which means a persons sense of individuality will be based on what they think about the most or what they like & value the most.
Extroverted Feeling, “Fe”, is the final function & is related to group harmony, sociability, and emotional intelligence. If Fi is Sympathy, then Fe is Empathy & being able to harmonize or deal with the emotions of others.
It’s a very important function to have & serves well to be diplomatic with others, to care for them, or understand what they are going through. Notice it’s all about the feelings of others, and that comes from Fe’s extroverted inclination. It’s not so much what the individual is feeling or values, but what the group as a whole feels is important.
