ISTP Cognitive Functions

Introverted Thinking bestows us with the gift of logic. Interrelated knowledge and patterns gear it up. Ti conquers life through an internal framework built by experiences and educated trial and error. It drives us to logically interlink everything we come across. Introverted thinking thrives in the act of rational troubleshooting. Ambiguity holds no place in it as it constantly pursues learning and growth. It empowers us to grasp how things work from the nitty-gritty to the most profound complexities.

The dominant cognitive function is the core of our ego and consciousness. Also called the ‘Hero or Heroine', the dominant function is our most natural and favorite mental process and primary mode of interacting with the world.

Introverted Thinking (Ti) in the dominant position endows ISTPs the gift of logic. It streamlines their thoughts and actions with logical consistency and rationalization rather than emotions. Dominant Ti helps them set their priorities despite being spontaneous. ISTPs come up with the best-fit answers and practical solutions through creating and first-hand troubleshooting. They see reality as it is and find ways to even make it better. These natural problem-solvers possess unmatched vigor and fascination in knowing how various things work for a specific utility.

Extroverted Sensing bestows us with the gift of senses. Tangible reality is its default battleground. Se conquers life through sensory experiences, enhancing their sight, sound, smell, and bodily movements. It lets us adhere to the stimuli of the physical world. Extroverted sensing ignites courage to seize moments while they last. It urges us to act right instantly instead of staying idle in the what-ifs.

The auxiliary cognitive function, known as the 'Mother' or 'Father', helps guide the dominant function in perceiving the world and is what we use when comforting others.

Extroverted Sensing (Se) on the auxiliary position balances their dominant Ti with the gift of senses through real-life data and experiences. It allows ISTPs to get in touch with their surroundings and be spontaneous with their actions. Auxiliary Se fosters them to immerse themselves in the real world without inhibitions, giving them their reputation for being very hands-on and responsive in crises. As they tap into their Extroverted Sensing function, they may ask questions like "What real-life experiences led into this situation?", "What can I do with the matter currently at hand?", or "What is relevantly happening around me?".

Introverted Intuition bestows us with the gift of intuition. The world of the unconscious is its working site. It is a forward-thinking function that intuitively knows without trying hard. It allows us to experience the unpredictable excitement of “eureka” moments through our unconscious processing. Ni also enables us to see beyond what meets the eye. It follows through an abstract pattern of how the world works and lingers on the whys of life.

The tertiary cognitive function is what we enjoy using to relax, calm, and take the pressure off our overused dominant and auxiliary functions. Known as the ‘The Child or Relief,' it feels like taking a break from ourselves and is playful and child-like. It is what we use when feeling silly, natural, and accepted.

Introverted Intuition (Ni) in the tertiary position relaxes ISTPs from being purely confined to logic and practical reality with the gift of intuition. Through this function, they can intuitively look at the future, understand unwritten trends, and entertain other alternatives instead of acting right away. They enjoy looking for unseen potential or symbolic connections in their surroundings. Ni unloads the self-absorbed burden on their shoulders to always be on the move and create something out of nothing. It allows ISTPs to have fun and playfully connect to their inner thoughts and understand the abstract patterns of life, including taking pleasure in being better at strategy games like poker or chess.

Extroverted Feeling bestows us with the gift of empathy. It advocates for the greater good than focusing on individual desires. It entrusts a strong sense of integrity and ethics. We instinctively tune in to moral and cultural values to maintain peace and harmony through this function. Fe enables us to feel for others even without fully experiencing their situations. It motivates us to keep and nurture our social connections and relationships.

The inferior cognitive function is our weakest and most suppressed cognitive function in the depths of our ego and consciousness. We hide this part of ourselves, embarrassed of our inability to wield it effectively. As we age and mature, we embrace and develop our inferior function, providing deep fulfillment from coming to the pinnacle of our personal growth and the end of our own hero's journey.

Extroverted Feeling (Fe) in the inferior position occupies the least space in the minds of ISTPs. They have trouble showing empathy and maintaining social connections due to their impersonal and logical demeanor. They tend to get shy and caught in awkward interactions as inferior Fe stands opposite their most prominent function, Introverted Thinking. ISTPs may feel unnatural as they extend their boundaries to socialize with others. Understanding human emotions has never been their forte leaving them confused and irritable. These personalities may find it easier to comprehend car engines rather than tuning into the complex and highly-charged feelings of others.

Extroverted Thinking bestows us with the gift of efficiency. It employs our analytical reasoning and objectivity. Te is forged in the supremacy of external systems, knowledge, and order. Extroverted thinking adheres to facts rather than fleeting emotions. It gives no time for silly chit-chats and focuses on purely significant matters. It boosts our passion and enthusiasm for informative discourse to expand our horizons of wisdom and knowledge.

The opposing shadow function, also known as the Nemesis, calls out our doubts and paranoia and acts in opposition to our dominant function, questioning the way it sees the world.

Extroverted Thinking (Te) in the opposing shadow position frustrates the individualistic ISTPs as it contradicts their dominant Ti. When they experience Te, they tend to be stubborn and defiant in following general rules and systems. ISTPs follow their own means of being effective and efficient. They may feel attacked and confused when other people enforce their ways on them. Consequently, their oppositional function instills paranoia and doubt, maligning those who outwardly express their insights and opinions.

Introverted Sensing bestows us with the gift of details. It consults the detailed past to gain wisdom while living in the present. We recall and revisit memories and acquired information through this function. It constantly stores sensory data to balance our current views and opinions. Introverted Sensing teaches us to credit proven facts and life experiences instead of mere instincts. It counsels us to avoid committing the same mistakes twice.

The critical shadow function criticizes and belittles ourselves or others and thinks nothing of humiliating and ridiculing in its search for control.

Introverted Sensing (Si) in the critical shadow position attacks the ego by casting regrets and lecturing on what should have been done. It criticizes ISTPs for repeatedly doing the same mistakes and missing out on the lessons of the past. They feel ashamed for falling short of their circumstances amidst the availability of details and relatable experiences in their minds. Critical Si belittles ISTPs for being impulsive and having a lack of discretion. As they tap into this function, they may start to think things such as "How could I have mishandled this very familiar circumstance?", "Why is this not arranged or in order?", or "Get out of your head and face the reality of life."

Extroverted Intuition bestows us with the gift of imagination. It empowers our life visions and sets us free from our limiting beliefs and built-up boundaries. It utilizes patterns and trends to connect with the tangible reality. Extroverted intuition is sensitive to impression and ambiance rather than specific details. This function thrives on venturing into the world's awestruck mysteries. It leads us to intuitively flow through the stream of anticipation on what is yet to be unleashed.

The trickster shadow function is sly, malicious, and deceptive, manipulating and snaring people into our traps.

Extroverted Intuition (Ne) in the trickster shadow position irks ISTPs with the gift of imagination. They prefer to act on real-life data than entertain different angles of possibilities. They feel overwhelmed and silly trying to brainstorm or theorize with others as they do not align with their most prominent function, Introverted Thinking. When they come across people who use Ne, they tend to malign their intentions and trap them into their own alternatives just to stop their perceived "nonsense".

Introverted Feeling bestows us with the gift of feeling. It navigates through the deepest corners of our thoughts and emotions. Fi flows through our values and seeks an in-depth meaning of life. It allows us to stay in the lane of our boundaries and identity amidst external pressure. This intensive cognitive function feels the pain of others and likes to be the knight for those in need.

The demon shadow function is our least developed function, deeply unconscious and far removed from our ego. Our relationship with this function is so strained that we struggle with relating to, and often demonize, people who use this as their dominant function.

Introverted Feeling (Fi) in the demon shadow position is the least developed function of ISTPs. As they struggle relating to their feelings, they get lost in introspection and become critically harsh of themselves and their surroundings. For example, these personalities may become passionate in fighting for a certain cause but as they tap into their Fi, they may appear to be self-righteous and insensitive instead of being genuinely persuasive. They tend to demonize Fi dominant users attuned with their inner emotions as they do not make sense to their analytical minds. ISTPs may also wield their demon function as a form of defense by shaming and pointing out severe loopholes in their opponent's morality and judgment.
