The psychological functions used are all the same. However, due to the difference between extroversion and introversion, the order of these psychological functions differs, resulting in both similarities and differences.
They often find common ground and empathy, which frequently leads to a rapid closeness and intimate relationship.
For this relationship, exchanging advice and ideas through conversation would be very constructive.
Here, as an example, we will show the psychological functions of ESTJ and ISTJ and their order.
- Extraverted Thinking/Te
Very good at it /First functionThey are skilled at objectively grasping specific facts using inductive reasoning (practical observation that leads to immediate conclusions). - Introverted Sensing/Si
I'm a little good at it /second function: To bear the responsibility and obligations to society, discipline, loyalty, and honor. - Extroverted Intuition/Ne
I'm not very good at it.Third functionThey aim for their actions and procedures to be effective in the future, but they can become neurotic if things don't go their way. - Introverted Feeling/Fi
I'm really bad at it /Fourth functionI feel anxious or afraid that I am not moral. I don't know how to confront (or don't want to confront) my own moral values.
<The cognitive axis of ESTJ>

- Introverted Sensing/Si
Very good at it /First functionThey are adept at matters of loyalty to others and themselves, and have a precise understanding of their position and civic duties. - Extraverted Thinking/Te
I'm a little good at it /second function: You are responsible for understanding and observing methodologies and systems, and for knowing whether what is currently being done is efficient in completing the action. - Introverted Feeling/Fi
I'm not very good at it.Third functionThey believe they possess the most correct ethical values. When challenged, they become rigid, arrogant, and stubborn. - Extroverted Intuition/Ne
I'm really bad at it /Fourth functionThey feel fear or anxiety towards novelty and unpredictability. They don't know how to take new measures that involve a certain degree of risk (or don't like taking them).
<ISTJ Cognitive Aspects>
Si – Ne: Accumulate sensory information to survive in a chaotic world.
Te – Fi: To show an effort to gain recognition.

You can see that not only the first and second psychological functions, but also the third and fourth psychological functions are in a different order. Because of this, the psychological commonalities are surprisingly small.
This corresponds to a relationship that becomes more active for a relationship type prone to conflict. Or, similarly, it corresponds to a relationship type prone to conflict for a relationship type that becomes more active.
In reality, problems often arise when people try to work together.
Introverts tend to be cautious and limit their activity. Conversely, extroverts encourage taking the lead, being out in the open, and being active, preventing idleness. Each has its advantages, but they often fail to understand each other's strengths and weaknesses, leading to irritation.
Furthermore, the third psychological function is the desire to be supplemented by others, but in this relationship, the other person suppresses this as their fourth psychological function, so it cannot be fulfilled.
The challenge for each individual is to balance their second and third psychological functions. However, this challenge is not the same for everyone.
What one person considers their primary psychological function is often the other's secondary function. Therefore, there is much to learn from each other's primary psychological functions. It's natural to show more interest in what one person recognizes as a potential strength.
However, when you're together, you tend to unilaterally assert your own strengths and try to attract the other person's attention.
It's only when we're alone that we can truly appreciate each other's good qualities.
In this relationship, the introverted type can come across as somewhat distant and stiff. The extroverted type, on the other hand, doesn't have a very good impression of this, becoming overly worried and suspicious. However, in reality, the introverted type doesn't have any particularly malicious intent.
