Actors want to make informed decisions. To hear, see, or intuit something, and then react or respond to it in some way or form. Perceivers want to reflect on how something is or appears to be. Reviewers are focused on acting on their values in some way or form. And deciders are mainly focused on making decisions based on their values. 













What are the cognitive functions?

The cognitive functions reflect unique ways in how we think and make decisions. You use iNtuition to imagine, sensing to experience, feeling to value, and thinking to measure. If you know this, you can also use this to boost your processing. You can make smarter decisions and you can boost your thinking. Experience life in richer detail by mastering your own cognitive functions. 






Extraverted intuition – Novelty

Extraverted Sensing – Experience

Extraverted Feeling – People

Extraverted Thinking – Resources

An extraverted process is constantly taking information from the outside and sending it inwards for evaluation and processing. Extraverted cognitive functions bring information from the world and extraverted types will be strong researchers and managers: people that can use the world to their advantage.

Extraverted iNtuition is looking at something, and then imagining how it could be different, seeing novelty. It can be noticing how different something is, noticing when something is unusual. You use it by imagining yourself as a detective and thinking of patterns and chains of events in a situation, and by considering things across contexts and seeing multiple ways to apply solutions to a problem.

Extraverted Sensing is thinking about how you experience a situation, what lights are on, what is too bright. It’s being able to take information from a situation and to use it to your advantage, and to adjust your environment and to put it the way you want it to be. You use it by imagining yourself as a scout, observing your surroundings and the nature and the environment. It’s a great quality of an adventurer or traveler or someone that often spends time in the spotlight or on stage.

Extraverted Feeling is thinking about what people you have close, who they are, what you like and dislike about them. It’s what is important to you, what values you have. What you care about, and what you think is right and wrong. You use it by thinking of yourself as an advocate, someone that stands up for those who are weak and who speaks out for what is right and wrong.

Extraverted Thinking is being aware of what resources you have available. Using it, you can decide what in your environment is of a higher value, and what is worth the most, who performs the best. You use it when you imagine yourself in the role of a director or businessman, thinking about opportunities to invest, important resources, strategical advantages.

Introverted intuition – Insight

Introverted Sensing – Knowledge

Introverted Feeling – Intentions

Introverted Thinking – Reason

An introverted process is constantly evaluating information inside of us and using it to understand the outer world. Introverted cognitive functions bring to light what you feel and what you think and your worldview and how you understand the world, and you can use this understanding to influence the world in various ways. 

Introverted iNtuition “The Philosopher”

Enhanced by mysteriousness (INXX)

Introverted iNtuition is what you use to theorise about a situation and to formulate questions and to look at an idea from different viewpoints. You use it by seeing yourself a philosopher, formulating answers to complex questions and reasoning about things people normally miss.

Introverted Sensing “The Instructor”

Enhanced by steadiness (ISXX)

Introverted Sensing is used when you imagine yourself as an instructor, someone that details out how to perform a task or how a situation works. You use it to explain what has happened and to decide how something is done. 

Introverted Feeling “The Counsellor”

Enhanced by sensitivity (IXFX)

Introverted Feeling is when you spot someone’s intentions and reasons for doing something. By introspecting on a situation, you can come up with emotional reasons and hidden intentions behind behaviour. You can troubleshoot actions and what people do. 

Introverted Thinking “The Critic”

Enhanced by intelligence (IXTX)

Introverted Thinking is used to analyse data and to think critically about a situation, how does it work, and what rules are in play? How can you improve at something or do it better than usual? The critic believes the world operates according to careful logical laws and seeks to master these laws and use it to their advantage.


Intuitive Perceiving – Change

Sensing Perceiving – Action

Feeling Perceiving – Evaluation

Thinking Perceiving – Calculation

A perceiving process observes and tracks for changes. We use it to anticipate and spot changes and to make adjustments and improvements to things. Cognitive functions that rely on perceiving give us the ability to adapt to the world around us and to be more flexible in our thinking. 

iNtuitive Perceiving – The Catalyst

Enhanced by creativity (XNXP)

iNtuitive Perceiving is a change oriented process, you use it to put terms and names on change and on what is happening around you, and to define options and various what-ifs. You use it by imagining yourself as a catalyst, someone who brings up change and shows differences and alternative methods of actions. 

Sensing Perceiving – The Doer

Enhanced by instincts (XSXP)

Sensing Perceiving is an action oriented process. You use it to chart a course of action, to take immediate action based on your instincts. To jump when you should jump, to move when you need to move. Sensing perceiving gives balance and the ability to act fast and well in an intense situation. 

Feeling Perceiving – The Reporter

Enhanced by honesty (XXFP)

Feeling Perceiving is used to evaluate a situation and to define how something feels or how you experience something. It’s used to decide if something is good or bad, or right or wrong. It gives you the ability to understand and map out how you feel about a situation and can help other people understand their own actions and their behaviour. 

Thinking Perceiving – The Trader

Enhanced by competitiveness (XXTP)

Thinking Perceiving is used to measure and weigh a situation, to count something out. Knowing this, you can weigh options and make good tactical decisions. You can put a value or number on something and decide if it is a good deal or not, and you can consider what actions other people are taking, and how to take proper counter-measures to stay ahead and to make sure you remain at the top. 


iNtuitive Judging – Speculation

Sensing Judging – Organisation

Feeling Judging – Diplomacy

Thinking Judging – Rules

A judging process directs and pushes a plan or idea forward, making way for something and making sure that it keeps on going the same way. The judging cognitive functions give us the ability to plan or map out how something should be done. 

iNtuitive Judging – The Speculant

Enhanced by focus (XNXJ)

Using this cognitive function, you can track a change process and determine in which direction a situation is going. Knowing how something works and how something is going to go, you can take proper measures and plan ahead and identify a good course forward. 

Sensing Judging – The Host

Enhanced by memory (XSXJ)

With sensing and judging, you can think of an experience and how an experience should go down. How do you want an event to happen and how do you want to conduct yourself. When and where do you want to do something and in what way? 

Feeling Judging – The Diplomat

Enhanced by caring (XXFJ)

With feeling and judging, you can think of the people around you and how you want to conduct yourself towards them. How do you want to speak with others and what kind of person do you want to become over time? What do you think people can become over time and how can you help them reach that? 

Thinking Judging – The Architect

Enhanced by ambition (XXTJ)

With thinking and judging, you can come up with systems and rules and strategies to do things. You can plan and you can use resources and knowledge to your advantage to come up with a way to execute or manage a project. You can use this function by thinking of yourself as the architect of a system, someone who has designed a system of tools and resources, putting it all in place.

You can use any cognitive function but certain personality types have a number of proficiencies and dispositions that make them more adept at using these cognitive functions. Being serious, being sensitive, being caring, creates a disposition towards a particular type. It gives you a strong aptitude when using certain cognitive functions. 

Sensitive types will have a disposition towards introverted feeling, but they can still use extraverted thinking. However, their sensitive nature will make them struggle to make tough calls and to remain strong under the material pressures.
