Cheat Sheet: Function Stack of Each MBTI Type

The 8 cognitive functions

The four extroverted functions are oriented outwards towards the external world, they are:

  • Extroverted Sensing (Se): Enjoying the finer aspects of life in food, fashion. Being physically in tune with the world
  • Extroverted Intuition (Ne): From one observation, deriving ten different ideas and possibilities
  • Extroverted Thinking (Te): Real-world practicality, results-driven, things that can be written down on a resume
  • Extroverted Feeling (Fe): Being able to “read the room”, attuned to the social atmosphere, tailoring your words to your audience

The four introverted functions are oriented inwards towards the subjective personal world

  • Introverted Sensing (Si): Seeing and remembering things as they were in the past, taking things step by step
  • Introverted Intuition (Ni): From ten observations, deriving one single theory that explains everything. Projecting the one future path that most likely will happen
  • Introverted Thinking (Ti): Logical and consistent, having various categories to ensure that everything has its own place in a water-tight system
  • Introverted Feeling (Fi): Having a clear idea of individual desires, values, tastes. Living life authentically without being affected by what the rest of the world does

Are You A Thinker Or Feeler?

Can I ask if you are left-handed or right-handed? The chance is you are a right-handed person, because it is the majority of our population. How do you know that you are right-handed? It is a very obvious question almost without a need to explain. If we need to break down the reasons, there are three ways you know that your type is a right-handed: 1) The frequency of you using your right hand in a day is higher than your left and 2) Your right hand feels a lot more natural and real and 3) Your right hand will objectively be better at handling heavier objects or more complex tasks. 

That is how you should think about your opposing function of Thinking and Feeling as well. Do keep the above ideas of left and right hand in mind as we further learn about the true definition of Thinking and Feeling in Jungian psychology.

If you are a visual learner, you can also follow this video below:

The definitions

Carl Jung

Besides Introversion and Extroversion, Thinking and Feeling are the second dimension in analytical psychology (the third dimension is Intuition versus Sensing). These concepts were first introduced in the early 20th century by Carl Gustav Jung (1875 – 1961), a famous Swiss psychiatrist who developed the idea of Psychological Types, the precursor to the extremely popular Myers Briggs Type Indicator (MBTI) test and framework.

My philosophy for Our Human Minds have always been to adhere as much as possible to the original understanding and work of Carl Jung to help readers understand accurately the cognitive functions. It is a longer path, but trust me, it is more rewarding and surer way to achieve more accurate self-understanding than purely taking the online test and read the descriptions of the 16 MBTI personalities!

Unlike left and right hand, Thinking and Feeling preferences in analytical psychology are more distinct, serving very different purposes. Your two hands do not oppose each other, but Thinking and Feeling do by definition. Hence, being aware of them and knowing how to develop your weaker function and learn to make them synchronize holds the potential for not only more productivity but also psychological maturity and wholeness.

The definition of  “Thinking” and “Feeling” in Jungian psychology are easily confused with the more layman definitions that we use in our daily languages. They should not be confused with logic versus emotion. You need to understand them in a more fundamental way, that they are evaluative & rational processes to judge incoming information, whether something is right or wrong, good and bad…

Thinking and Feeling aim to clearly distinguish between the two distinct preferences for decision-making: impersonal versus personal/interpersonal respectively. The easiest way to visualize this difference is in the common stereotype between men versus women in our society. Men are known to prefer to “solve problems” and break down problems “logically” while on the other hand, women simply want to be listened to, to be empathized and understood. 

Thinkers (both men and women) prefer to solve problems objectively

While this is a stereotype, indeed, some of the surveys  have shown that there is a slight preference (55%) among men for Thinking and a strong preference (75%) of women who have a Feeling preference. How much of this is the surveyed individuals’ true preferences and how much is a result of social expectation & conditioning, is for another debate. However, I would like to add that based on this survey, thinking that all men are or have to be super logical or women have to be relationship-oriented is a gross simplification and unfair treatment to both sexes.

To break it down further, thinking manifests itself as preference for using objective and measurable frameworks for clear-cut decision making. It is about using objective criteria, conceptual frameworks, pros and cons, structures, logical systems… People with Thinking preference value and take pride in being efficient, precise, goal and task-oriented. Something is good if it is placed in the right category, gives better measurable results, more efficient etc.

On the other hand, Feeling places stronger emphasis on human’s welfare, values and preferences. As an introverted function, it’s about knowing a strong moral sense of right and wrong, of feeling an urge to help the less fortunate, to be humanitarian, to overcome unfairness and restore equality. Extroverted version is about about maintaining a harmonious atmosphere (when hosting a house party for example), making sure common pleasantries and “civilized” etiquettes are adhered to, while making sure everyone has a good time.

Quick Exercise : What is your true preference based on the above definition?
You might need to think about when you are younger or in a more comfortable place at home without any stress of work or “have to” pressure. Social expectation and work stresses might force us to over-compensate to the point of losing sight of who we truly are, like Feeling men are often expected to appear logical and tough, or your jobs have required you to develop your weaker function, even if in your younger years you are the opposite.

Develop Thinking

This section is more relevant for Feeler who has a natural strength in making decisions based on personal values or harmony, but as a result, devoting less consciousness energy in using systemic/impersonal perspectives. We will look at concrete steps that you can take to gradually build up confidence in using the skills and become more holistic in decision making.

Playing a big part of your ego, Feeling – the preference for using value and personal-preference based approach, is part of your identity. The cause that you care about, friends and family, the social connection and status that represent your deepest conviction and meaning of life, are valid. As much as it’s important to acknowledge the other side of the equation, in the end, Thinking should serve in a supporting role and not to dominate your preference for  personal values or interpersonal harmony.

Just like this two-people bike, you should let your dominant function to take the lead and guide the other function, not the other way round!

The development of your weaker functions and achieving wholeness is a life-long quest, so the instruction below serves as a general direction and examples of the kind of steps you can take to develop Thinking.

Remember that the basic definition of Thinking is the use of impersonal systems, framework and measurable results and data. Hence, you can:

  1. Learn from someone close to you who is strong in Thinking like your family members or colleagues. Talk to them more or reflect on the time you guys spend time together. Learn about how they conduct themselves differently, understand why they do it and see if you can learn and integrate some of their techniques or philosophy.
  2. Develop interests in activities that require strong impersonal reasoning and decision making such as chess, finance, computer games…
  3. Integrate productivity tools such as planner, calendar, deadlines and KPIs clearly for both personal work and managing others.
  4. Take courses, read books, watch videos… on productivity, time and project management.
  5. Learn to say No. It’s very natural for Feeler to go with the flow and say yes to keep harmony. Saying No doesn’t mean being harsh or rude if you can explain yourself clearly. It doesn’t have to be black and white either, you can also negotiate what you’d like to do and what you cannot do or you feel is not fair. It’s hard at first, but it’s an essential skill that will go a long way!

Develop Feeling

This is more relevant to Thinking dominant type. Again, it’s important that you acknowledge and embrace your identity as a Thinker and develop Feeling as a support for a more holistic decision making process. Your Thinking function should still be in the driver seat!

  1. Find friends, family or colleagues who you know well and you are fairly certain they are stronger in Feeling. Get to know them more and reflect on how they conduct things differently and see whether you can integrate some of their physiology and methods to your daily life.
  2. Engage in reflective activities like meditation, arts, writing… to reflect on your values and what’s important to you. Remember, it’s a gradual process that requires patience and regular practices.
  3. Engage in social activities and roles that you have to interact more with people. Recognise some of your biases and see it from a more positive light when it comes to social relationships. 
  4. Immerse yourself in nature, away from distraction of work and technology, to hear and embrace your inner voices, values and feelings.

Are you a Thinker that has other ways that work? Feel free to share below.

I hope you now have a clearer understanding of the distinction between these rational dimensions of Thinking versus Feeling. In reality, these two preferences never exist as standalone in a healthy person’s psyche but work in tandem. But since they are mutually exclusive/cancelling out, it’s natural to prioritize and put your conscious energy into one while “send to exile” the other, giving little conscious energy to nourish and maintain it.

If possible, you should learn further about how Introversion and Extroversion are combined with Thinking and Feeling to give rise to 4 distinct Cognitive Processes/Functions: Introverted Thinking, Extroverted Thinking, Introverted Feeling and Extroverted Feeling. This breakdown will bring in a whole new level of depth and opportunities for self-understanding and development. Good luck!
