ESTP Auxiliary Function: Understanding the ESTPs Secondary Introverted Thinking (Ti) 

When searching for a deeper understanding of the personality types, it is important to understand each one of their functions. While we often focus on the dominant and even inferior functions, knowing the auxiliary and tertiary ones are also vital. It is not just about knowing what functions each type possesses but rather how these functions behave within the stack. When a function is dominant it will present differently than when it is auxiliary, and so understanding this is truly important if you want to understand each personality type. Knowing each function on it’s own doesn’t really give you a true comprehension of how the personality type is going to utilize  that function. Instead you need to learn more about the placement of each function and how it corresponds with each personality type.

ESTPs are often outgoing and charming people who love to experience new things. They dislike feeling stuck in one place, and want to be able to enjoy the present moment. The ESTPs dominant function is often what people notice about them first, since it is their extraverted function as well. Their extraverted sensing is what causes them to live so much in the present moment and feel a strong connection to the physical world around them. While this is certainly an important function for the ESTP, they utilize their auxiliary function quite a bit as well. The ESTP auxiliary introverted thinking or Ti, helps to aid the use of their dominant function. This supports their Se and gives them a sense of direction, instead of allowing the ESTP to just bounce from one thing to the next without clarity or a sense of direction. This is why their aux function is so important and something which should be understood better.

How Ti Works

Introverted thinking (Ti) is used as an internal framework which helps the user navigate the world around them. These complex systems inside of their minds are how the Ti user sees and understands the world. It helps them to make decisions and come to logical conclusions about what they see and experience. They are constantly modifying this when new information is uncovered, willing to absorb new facts and details and adjust how they view things because of it. They are constantly weighing new information against their already existing model, wanting to be sure that everything works and makes logical sense. If information doesn’t seem to fit into this internal system, the Ti user will reconsider how they are processing things in order to uncover where the inaccuracies are. This helps them to become amazing problem solvers, always prepared to look at the details and uncover ways of ensuring that they can fix whatever is going wrong. They are not afraid of approaching a new situation, where others might need to look at things which have been done before in order to find solutions. Instead the Ti user doesn’t need proven methods, since they operate based on this internal thinking system rather than something external. Since their knowledge is not based on what others have accomplished in order to figure out answers, the Ti user can problem solve using their own inner minds and understanding of the information in front of them. This Ti is amazing at uncovering problems and finding solutions which will be more efficient and work in a long-term manner. They are always searching for ways to improve processes, wanting to uncover the most precise and accurate means of solving the problems they find. This Ti is constantly searching for better means of understanding the world and how things work, as well as finding the best ways to navigate the world with strategies and solutions.

Auxiliary Ti in ESTPs

ESTPs might take in a lot of experiences and information through the use of their Se, but it is their auxiliary Ti which makes sense of all of this. This introverted thinking makes the ESTP seek out ways to better understand the world around them, wanting everything to make logical sense inside of their minds. This inner framework is used to sift through information they gather from the world around them, wanting to make things clear and logical. ESTPs are still spontaneous people who often want to leap into things in order to experience them firsthand. While this can cause them to jump into some tricky situations at times, their Ti is what helps them to learn from this and find a clear direction for the next time. They use this to understand which is the most logical and rewarding path for them, and to keep them from jumping into things without at least considering a better option the next time around. Instead of emotions deciding for them, the ESTP is driven by a sense of logic and wanting to understand the facts of a situation first.

This Ti is part of what causes the ESTP to be so caught up in problem solving, wanting to really dig deeper into fixing things. They might even enjoy working with their hands, and being able to take things apart and see how they actually work. This is because their Ti is something which aids their Se, making the ESTP a more hands on learner and problem solver. ESTPs often want to be able to become better when it comes to most hands on skills and things which require them to really dig deep into the problem. They enjoy fixing things and being someone who can express the facts to those around them. Because of this Ti ESTPs dislike ignorance and inaccuracies, and are often willing to correct people when they are completely wrong about something. This isn’t always a part of them which is seen outwardly, since it kicks in during certain situations. This is because ESTPs often appear more laid back on the outside, wanting to live in the present and experience the moment to the fullest.
