1. Te – extroverted Thinking
Te is the primary way TeNi’s interact with the world around them. Te is all about efficiency and getting things done. It is the TeNi’s primary decision-making process, which means that if a decision is needed in the moment, they will rely on what makes the most sense logically. They are primarily concerned with moving forward and are not interested in wasting time and energy nitpicking a solution to death before applying it. Their solution is the “perfect” solution in the moment. The best, most effective solution is often obvious to them, and they are masters of maximization and efficiency.

2. Ni – introverted Intuition
Ni is the way that a TeNi perceives their inner world, it dictates the way they store information and how they perceive that information. It also heavily dictates the path that their train of thought will take. Ni tends to store information in a spread out way with all the pieces of data having connections of various strengths to multiple additional pieces of data. This creates a dense web-like mass of information that is too large to be viewed in detail as a whole, but can be zoomed in on to show intricate clusters and threads of thoughts.

This network of data rests slightly outside of the conscious mind, giving Ni a dreamlike quality that is equally likely to be experienced in images and impressions as it is to produce concrete facts. Because the focus of the Ni perception is constantly scanning the whole but also frequently zooming in on various thoughts and feelings and changing angles on a subject, they tend to experience their inner world as constantly fluctuating.


3. Se – extroverted Sensing
Se helps the TeNi use their senses to understand the world around them. They enjoy living in the moment and are capable when it comes to dealing with things that they can experience and touch in addition the purely hypothetical. This is because their Ni and Se fall in the middle as far as preferences go, so they’re able to flip back and forth to use each one as it’s needed. Se is also what drives them to search out playful new sensory experiences.

4. Fi – introverted Feeling
Fi is their last function. Fi helps them to assess situations to see how things match up to their values and beliefs. They may think of their Fi as their “gut instinct”. It helps them learn to be sensitive to the values and feelings of those around them. It can act as a warning system when they think a decision makes sense logically, but somewhere inside, Fi is the alarm saying it’s a bad idea. However, because Fi is the TeNi’s weakest function, they will often act with the swift decisiveness of Te first, before considering how their actions might affect the feelings of others or taking time to think about whether their decision lines up with their values.
