Also, in advanceFour psychological tendency axesKnowing the following will also help you understand morePsychological functions (cognitive functions)You can understand this.


Introverted Thinking (Ti) is
People with a dominant introverted thinking (Ti) tend to ask themselves, "Is this consistent, logical, reasonable, and convincing?" When data is contradictory or inconsistent, you use introverted thinking (Ti) to organize and summarize it. When you make a decision based on theoretical consideration and logical analysis, even at the expense of personal desires, social norms, common sense, or expectations, you use introverted thinking (Ti) as the basis for your decision-making.
Introverted thinking (Ti) is driven by facts far more than people. Personal desires and emotions can get in the way of pure data, and sometimes other people may become the subject of data in order to pursue logic. However, people with a dominant introverted thinking (Ti) are not necessarily cold-hearted. Seeking the truth is the ultimate virtue, but anyone with a dominant introverted thinking (Ti) knows that the interpretation of truth is subjective and depends on the individual.
If you strongly resonate with this introverted thinking (Ti) function, you were likely sensitive to contradictions and inconsistencies, especially discrepancies between words and actions, from a young age. In your youth, this usually manifested as a difference between what you "said" and what you "did." Even when given orders by adults or those in positions of authority, if you yourself did not follow those orders, you would immediately notice the contradiction and feel compelled to point it out.
For example, a typical example of someone whose introverted thinking (Ti) is dominant isINTPHowever, when presented with a paradoxical hypothesis, we try to find a contradiction that leads to one of the following:
- Selection of new hypotheses
- Modifying new hypotheses to integrate them into one's own logical structure
- Modifying your logical structure to accommodate new hypotheses.
Also,INTPINTPs organize their thoughts using a true/false dichotomy. They ask themselves, "Is this idea true or false?" and "It cannot be both." They think, "To make such a claim is to negate logic itself!"
People with a dominant introverted thinking (Ti) often complain that they were called ill-mannered and rebellious as children. This wasn't their intention. What they intended was consistency in their thinking, and everything would have been forgiven if those in authority could clearly explain why they, as adults, didn't need to follow the same rules as children. However, explanations like "because I'm an adult" or "because I'm in charge" didn't seem convincing and didn't work. Thus, developing a sense of fair play is also a result of introverted thinking (Ti). The core of introverted thinking (Ti) is correcting contradictions, which involves organizing a lot of ideal data without impurities in order to obtain the clearest possible view. However, human emotions are fickle and never simple. Therefore, when it comes to making a decision, emotions take a backseat.
This story illustrates how society can accept collective illusions in order to maintain the position and status of individuals. In this story, the child is not afraid to defy the collective illusion and points out what is obvious to him: the emperor has no clothes. Social status, personal desires, and the fear of being blamed are all completely irrelevant in the face of logic and observable facts.
Those who have mastered the function of introverted thinking (Ti) check and discard information and beliefs that do not pass their rigorous internal standards. Just as a computer programmer finds bugs, people with dominant introverted thinking (Ti) will try to remove any code that could potentially destroy the rest of the program. If you are mistaken or mistaken about something and someone with dominant introverted thinking (Ti) points it out and corrects you, it's not someone else's problem. They genuinely want that information themselves, and they expect you to do the same.
Details of Introverted Thinking (Ti)
As an introverted psychological function, attention is directed inward. As a thinking psychological function, rational decision-making is carried out according to logic and principles.

Types whose primary psychological function is introverted thinking,ISTP (Practitioner type), INTP (Researcher Type)is.
For types whose second psychological function is introverted thinking,ESTP (Adventurer type), ENTP (Inventor Type)is.
Introverted thinking involves continuously building a logical set of criteria for judgment within the conscious mind.
We start from definitions, axioms, principles, and fundamental rules, and trust the conclusions we reach through reasoning.
I often come up with elegant solutions through my own unique thought process.
On the other hand, if your thinking becomes too complex, others may not understand how you arrived at your conclusions. Furthermore, even you yourself may lose sight of the solution when you're lost in thought.
I delve deep into how things work and how the system functions to understand it as thoroughly as possible.
By continuously making inferences in my mind based on hypotheses and principles, I can quickly notice any contradictions.
They are keen to identify what is wrong and why, and they try to pursue the matter without being swayed by personal feelings.
It takes time to become certain that something is correct, and we try to increase the likelihood by endlessly building up reasoning. Therefore, rather than being certain that something is correct, the criterion for judgment becomes whether it is unlikely to be wrong, or whether it is more efficient.
Rather than simply valuing practicality or custom, they strive for a deep understanding with a skeptical attitude.
Through classification and analysis, I strive to thoroughly understand how systems work. Whether it's a natural object or an artificial device, I'm interested in what's inside and how it works.
To understand the function of each part and the relationships between them, you might actually try to disassemble something. However, this isn't always possible, so you'll end up accumulating knowledge by thinking about it and reading books.
For those with a strong introverted thinking style, flaws and contradictions are fatal. They can discern the root cause of a problem and its resulting consequences.
Once I reach a reliable understanding, I then use that understanding to develop a strategy for problem-solving. Furthermore, I find it inefficient and unbearable to repeat the same thing over and over.
We maintain a rigorous scrutiny even in quantitative comparisons. We conduct reasoning in pursuit of consistency and consider whether the derived conclusions can be accurately evaluated by the model. By repeating this process, the accumulated knowledge is seamlessly integrated into a larger theoretical framework.
In this way, knowledge that serves as the basis for judgment in one's thinking continues to grow internally. By thoroughly exploring the mechanisms and understanding the function of each part, one can obtain efficient ideas for problem-solving. This is because one can realize which parts to change, how much improvement will be achieved, and which parts to modify in the most efficient way to improve.
As an introverted psychological function, it is something that is refined within an individual. The criteria for judgment based on this way of thinking are not conventional and may not be accepted by everyone.
Because it is based on deep and continuous reasoning and a vast amount of knowledge, sharing that reasoning process with others is difficult and requires considerable effort. If forced to do so, one might try to get by by briefly explaining only the key points.
I strive to define terms as precisely as possible and communicate my meaning accurately. This eliminates ambiguity and allows me to identify efficient points for explanation.
Individuals with a strong introverted thinking style demand strict self-discipline. They consider it foolish to follow vague reasoning or unrealistic wishful thinking based on wishful thinking. They believe that following conclusions derived from logical thinking is ultimately beneficial. Therefore, they think and judge things autonomously, and are proactive and independent.
On the other hand, they may lack consideration for the feelings and relationships of others. To others, they may appear distant and cold.
And they don't realize that this actually leads to isolation, a lack of positive feedback, and ultimately, to their own disadvantage.
Since a person's consciousness develops centered on themselves and gradually expands its scope, it is natural that conclusions and knowledge derived from introverted thinking are primarily used for one's own benefit.
You might be tempted to keep your knowledge hidden if it allows you to monopolize the benefits. On the other hand, I recommend considering whether it's beneficial to spread your knowledge, build cooperative relationships, and share the benefits with others.
Introverted thinking provides personal knowledge and guidance, but because of its inquisitive nature, it often stands out for its certainty and can frequently benefit others.
When one's interests are focused on a narrow range, they tend to become selfish. And this type, in particular, seems to have a hard time breaking free from their selfish nature.
As the scope of knowledge sharing and adaptation expands to groups, regions, and the world, it will ultimately benefit everyone.

Projection of Introverted Thinking (Ti)
Projection arises from anxiety and fear about things you don't want to acknowledge, and conversely, from a desire to acknowledge things you do want to acknowledge.
Everyone has fears. Humans have strived desperately to avoid succumbing to those fears.
Therefore, each psychological function (cognitive function) has its own anxieties (things you don't want to be) and desires (things you want to be) that you unconsciously don't want to admit to yourself.
Your psychological functions improve as you desperately try to overcome the following anxieties. And, after using them for a long time, you'll find yourself using them skillfully and unconsciously without even realizing it.
Examples of projections associated with introverted thinking (Ti) ↓
- My anxieties and worries
- I believe lies.
- I am lying.
- I am foolish.
- I am an incoherent and imperfect human being.
- I am giving an inaccurate and insufficient explanation.
- Hidden desires within myself
- I can see through lies.
- Customers tell the truth
- I am intelligent.
- I am original and innovative.
- I am good at explaining concepts.
The Big Five personality traits and introverted thinking (Ti)
The Big Five personality model is considered the most reliable personality analysis in the world, and was proposed by Lewis R. Goldberg, a psychologist and professor emeritus at the University of Oregon. As the name suggests, the Big Five classifies a person's personality into five factors.
Explanation of the five personality traits (factors) of the Big Five personality model ← Tap

- Biological mechanism: Response inhibition (dorsolateral prefrontal cortex)
*A strong judging function means that the primary function is either thinking (T) or feeling (F), while a strong perceptual function means that the primary function is either intuitive (N) or sensing (S).
The relationship between the Big Five personality traits and the 16 personality types has been investigated, and the table below shows the correlations. By comparing which personality traits and their sub-traits (facets) each psychological function correlates with, you can gain a more detailed understanding of the tendencies of each psychological function.

Introverted Thinking (Ti) has three attributes: Introversion (I), Thinking (T), and Judging (T or F). The Big Five personality traits corresponding to each attribute are as follows:
- Introvert (I) → extraversion (low)
- Thinking type (T) → Cooperation (low)
- Judgment function (Ti) → Honesty (High)
