When first met with a problem the INFJ seeks solution the easiest way; the introverted intuition, Ni. If that does not work, the INFJ uses their second function, Fe. Then the third, the fourth…The third and fourth cognitive functions are not developed enough to solve problems that the cognitive functions couldn’t solve.
Step One. The INFJ resolves to find an escape through their fourth function, extraverted sensing. This function is what makes a stressed INFJ overindulge in sensory activities such as eating, sex, watching to many movies etc. The INFJ begins to act like an unhealthy ESTP. The INFJ begins to forget about their purpose and future and start living in the moment.
Step Two. The INFJ continues trying to find a solution to the problem by referring to the other four cognitive functions. The moment s/he begins to do that, it drains the INFJ tremendously as this means Using more mental energy trying to access cognitive functions that are less and less developed. At this stage the INFJ uses their extraverted intuition, Ne, a cognitive function that enables them to see a variety of solutions to the problem. Within the INFJ, this function is not well developed, therefore the INFJ uses tremendous energy in efforts to access it, while being unable to draw answers from it.
Step Three. The INFJ looks morals and principles stored in a lesser developed cognitive function, introverted feeling, Fi. The slot here is of a pessimistic nature. The Fi is also part of the reason why Fi is constantly striving to know what they feel as their extraverted feeling nature overshadows this function.
Things become darker and darker as the INFJ keeps searching for solutions through cognitive functions placed in the lower — and more unconscious — parts of the mind. Once the INFJ sees how neither the conscious or unconscious can help find an answer, they will look to their subconscious. Then finally they turn to the superego. That Is when everything begins to burn down.
Solution
In all personality types, the auxiliary function is responsible for keeping everything together. It is responsible for the maturity of the person. It is responsible in keeping everything intact.
The INFJ is responsible for finding solutions to their problems using extraverted feeling. They must know how to find out how they can be ethical towards themselves. INFJs must know how to stand up for themselves and take full responsibility for everything they do or say. They must begin to pick up their own slack and start moving. Extraverted feeling is the best parent the INFJ has, the INFJ must learn and know how use it to regulate themselves in trying times.
