Are you looking to understand more about the ISTP personality type? If so, learning about their cognitive functions is a great next step. ISTPs are known for their easy-going, practical approach to life—but there’s much more to ISTPs than just that. In this guide, we’ll dive into ISTP cognitive functions, which can give you valuable insight into how people of this personality type think.
But first, what are cognitive functions? Cognitive functions are modes of processing information and making decisions based on your personality type. They form the basis of how we think and draw conclusions.
Each personality type primarily uses four cognitive functions, and the position of each one impacts how each person uses it. This order is sometimes referred to as a “function stack.”
The ISTP cognitive function stack is as follows:
1. Dominant cognitive function = Introverted Thinking (Ti). ISTPs use this function to analyze data and draw logical conclusions.
2. Auxiliary cognitive function = Extraverted Sensing (Se). ISTPs use this function to take in information using their five senses.
3. Tertiary cognitive function = Introverted Intuition (Ni). ISTPs use this function to make sense of information through pattern recognition and convergent thinking.
4. Inferior cognitive function = Extraverted Feeling (Fe). ISTPs use this function to understand other people and navigate relationships.
Delving into the ISTP cognitive functions
Let’s look at each of the ISTP cognitive functions in more detail.
1. Dominant cognitive function: Introverted Thinking (Ti)
Introverted Thinking is an ISTP’s dominant cognitive function. This means that it’s the most influential in their function stack. It’s the cognitive function ISTPs use most often and with the greatest ease.
Introverted Thinking is one of the processes that help us make decisions based on our inner world. It’s about taking into account your inner framework of logic and web of knowledge. If Introverted Thinking was a question, it would be: does this make sense to me?
This cognitive function is all about understanding how the world works. It’s associated with ensuring that data and information are accurate. As a result, ISTPs tend to be logical and realistic. They usually have a talent for problem-solving and like to know the reasoning behind things. This is also why they come across as laidback—they don’t like to make big decisions without knowing all the facts, so they’ll often just put it off.
ISTPs use Introverted Thinking to analyze and evaluate situations, looking for flaws in arguments or potential solutions. In particular, they use it in conjunction with their auxiliary cognitive function, Extraverted Sensing, to pick up on inconsistencies or changes in their physical environment. If ISTPs notice something amiss, they use Introverted Thinking to try and work out the reason behind it. Essentially, it enables ISTPs to think critically about a situation, motivating them to verify information and check its accuracy instead of taking it at face value.
One of the greatest strengths of ISTPs is that they have a knack for finding practical solutions to real-world problems. They are naturals at troubleshooting and figuring out how things fit together. Since they generally use this function with Extraverted Sensing, they prefer to tackle problems head-on and learn through trial and error.
Introverted Thinking is about understanding how things work rather than efficiently completing tasks. In ISTPs, this manifests as a practical, measured approach to problem-solving and decision-making. ISTPs draw relevant facts from their environment, see how it fits in with what they already know, and then make a logical decision. They might take their time before coming to a conclusion because they want to fully understand all the nuances of a project, task, or situation.
When an ISTP takes in new information, they will compare it to their existing internal framework of how the world works. If it fits, then voila, they have a new piece of information to add to their database. However, if it doesn’t fit their existing understanding, they will reconsider the new and old information to determine where the inaccuracies lie. If necessary, they will seek out additional facts to help them understand.
As ISTPs primarily use Introverted Thinking in conjunction with Extraverted Sensing, they do some of their best analysis when on their feet. Think about a football player making split-second decisions in the heat of a game about the angle and speed to kick the ball. This is a great example of Introverted Thinking and Extraverted Sensing working together quite literally in action.
This combination of functions means that ISTPs often enjoy video games because they allow them to take advantage of their analytical skills related to Introverted Thinking. In addition, video games are often full of unpredictable changes and challenges that require quick adaptation, which is another area where ISTPs excel.
2. Auxiliary cognitive function: Extraverted Sensing (Se)
Extraverted Sensing is an ISTP’s auxiliary cognitive function, which means it’s the second most influential in their function stack. It’s another area where their strengths lie, but not to the same extent as Introverted Thinking.
Extraverted Sensing is one of the processes that help us understand the world around us. It’s about experiencing and perceiving the external world in the present, and it involves taking in information using our five senses. If Extraverted Sensing was a question, it would be: what am I physically experiencing right now?
This cognitive function is all about tangible information. It’s associated with action, movement, and the “here and now.” As a result, ISTPs tend to be highly aware of their surroundings. They are usually able to notice even very subtle changes in their environment. ISTPs have confidence in their ability to react as things happen, which is partly why they don’t feel a need to plan too far into the future.
ISTPs are known for their ability to be present, and these qualities are heavily influenced by their Extraverted Sensing cognitive function. People of this personality type need to be kept entertained. While they aren’t the kind of people to be out socializing all the time, they can get bored easily and often need to move around or do something that keeps their minds and body engaged. For example, working out or playing a game.
ISTPs are often seen as risk-takers because they aren’t afraid to push their physical limits in order to experience new sensations and encounters. This is how they feel energized, and it can give them a sense of accomplishment. ISTPs have confidence in their physical abilities — they are naturally agile and quick on their feet.
Extraverted Sensing also explains why ISTPs embrace sensory pleasures and experiences. They are known for enjoying good food and walking in nature. Essentially, they need to stay connected to the external world to feel fulfilled and grounded. However, in some cases, this can manifest in an unhealthy way, such as overindulging in drugs or alcohol.
ISTPs don’t tend to overthink and have a natural ability to adapt to different situations. In fact, they are one of the most easy-going personality types, and their cognitive functions play a role in this. Not only does Extraverted Sensing enable ISTPs to stay present and grounded, but it also gives them a sense of self-assurance that they will be able to deal with situations as they arise. When you add Introverted Thinking into the mix, ISTPs have a formidable combination of logic and alertness.
Extraverted Sensing is about taking in information using your five senses, and, as a result, ISTPs often appreciate aesthetic beauty—more than most other personality types. ISTPs tend to be very visual and often seek out places and experiences that are visually pleasing and uplifting. They usually appreciate art, music, and nature too.
ISTPs are natural “doers.” While they might not enjoy the strategy and planning side, they are great at getting on with it. In particular, they are often exceptionally talented at practical tasks. ISTPs tend to be skilled in areas such as woodwork, mechanics, and home renovation — anything that involves using their hands.
ISTPs need flexibility in their life to feel their best, and this is another area where Extraverted Sensing plays a role. They need to be able to move around, explore, and take in their environment. They can struggle in monotonous and structured environments, which goes against their natural instincts. They need freedom to do things their own way and explore the world around them in their own time. Being booked up weeks in advance with little time for spontaneity is a sure way to make an ISTP feel stressed and restricted.
3. Tertiary cognitive function: Introverted Intuition (Ni)
Introverted intuition is an ISTP’s tertiary cognitive function, which means that it’s the third most prominent in their function stack. Our tertiary cognitive function tends to be noticeably less developed than our first two.
Introverted Intuition is one of the processes that help us understand our inner world. It’s about using intuitive internal analysis to understand how things work. If Introverted Intuition was a question, it would be: what is your gut instinct?
This cognitive function is all about taking information and making sense of it through pattern recognition and convergent thinking. It’s associated with relying on intuition and being able to envision how future events could unfold. As ISTPs use Introverted Intuition lower down in their function stack, this ability is less prominent than in other personality types who use it as their dominant function.
While ISTPs are more comfortable with tangible information and facts, they can tap into their intuition. This allows them to make sense of the information they’ve taken in using Extraverted Sensing and analyzed using Introverted Thinking. Essentially, they’ve absorbed the information and analyzed it; now, they need to understand how it fits into the big picture. This is where Introverted Intuition comes in handy.
In particular, ISTPs use introverted intuition to solve problems. More often than not, these are practical problems, but they can also be theoretical. By using their Introverted Intuition cognitive function, they can think outside the box and come up with creative solutions. However, they can only maintain interest in theories and abstract concepts for a certain amount of time. They simply don’t see the point in spending hours talking about topics that don’t have real-world applications.
Introverted Intuition involves trusting your gut and taking leaps of faith based on what you think will work best. Since this function is in the tertiary position for ISTPs, they prefer to test solutions quickly in the real world rather than sitting for hours mulling over abstract theories. If the solution works, then great. If not, they’ll try the next one on their list.
Introverted intuition plays a role in the ability of ISTPs to take calculated risks. It’s a forward-looking function that can envision how scenarios will likely play out in the long run. When ISTPs use this alongside their Introverted Thinking cognitive function, they can easily make decisions quickly and accurately.
ISTPs prefer to live in the moment and take things as they come, but they do take a step back and look at the bigger picture now and again. This is a result of their Introverted Intuition. It helps to keep them on track and have the foresight to consider what will happen next. However, as Introverted Intuition is in the tertiary position for ISTPs, they don’t always consider the consequences of their actions as much as they perhaps should.
4. Inferior cognitive function: Extraverted Feeling (Fe)
Extraverted Feeling is an ISTP’s inferior cognitive function which means they can struggle to access it as easily as their other functions. Using your inferior cognitive function as a strength is possible, but not for a prolonged period.
Extraverted Feeling is one of the processes that help us make decisions based on the outer world. It’s about taking into account the emotions of others and what’s best for the group. If Extraverted Feeling was a question, it would be: how do others feel about this?
This cognitive function is all about understanding people’s feelings, social dynamics, and hierarchies. It’s associated with picking up on social subtleties, and it has the desire to maintain harmony. However, it’s the inferior function of an ISTP, so it tends to manifest more as a weakness than a strength.
One of the key ways that inferior Extraverted Feeling manifests in ISTPs is that they can struggle to read people. They don’t always pick up on how others are feeling because they just don’t have that natural ability. As such, they might misread social cues or entire situations, leading to awkward conversations and misunderstandings.
ISTPs can also have difficulty understanding how their words and actions impact others. In particular, they can struggle to know what to say when someone is sad or angry. While it’s never their intention, this can lead to them coming across as uncaring or even insensitive. Additionally, they can find it hard to feign interest if they aren’t enjoying a conversation.
At times, ISTPs can struggle to express their emotions in a healthy way. Since Extraverted Feeling is an inferior function for this personality type, discussing their feelings doesn’t come easily to them. This can lead to them bottling up emotions or entirely avoiding conversations about them. Either way, it can have an adverse effect on them in the long run.
Emotions are often confusing for ISTPs because they focus on facts and logic. At times, ISTPs might overthink their feelings and try to intellectualize them. This can lead to them losing sight of the actual emotion. They can also find other people’s emotions confusing and overwhelming, causing them to shut down or become uncomfortable in situations involving intense feelings.
Inferior Extraverted Feeling in ISTPs can also manifest as conflict avoidance. Because ISTPs are uncomfortable dealing with emotions and social dynamics, they can end up trying to avoid conflict altogether, particularly if they think it will get heated. As a result, they can end up burying their heads in the sand rather than dealing with the problem head-on. This can be detrimental to their relationships as well as their own development if it’s not addressed.
