The eight functions are listed below. I will describe them in greater detail on the next article. This article is just so that you can get familiar with how they are organized.
- Introverted Thinking (Ti)
- Introverted Feeling (Fi)
- Introverted Sensing (Si)
- Introverted Intuition (Ni)
- Extroverted Thinking (Te)
- Extroverted Feeling (Fe)
- Extroverted Sensing (Se)
- Extroverted Intuition (Ne)
| Judging Functions | Perceiving Functions | |
| Introverted Functions | Ti Fi | Si Ni |
| Extroverted Functions | Te Fe | Se Ne |
Introverted Functions – Four of the functions are introverted. They are directed inwards, internal, rarely exposed to the outside world and will be filtered by the person’s extroverted function causing the actual introverted function to often be misunderstood. Introverted functions are developed internally by looking inwardly in the way that the function requires.
- Introverted Thinking (Ti)
- Introverted Feeling (Fi)
- Introverted Sensing (Si)
- Introverted Intuition (Ni)
Extroverted Functions – Four of the functions are extroverted. They are directed outwards, external, how we interact with the outside world, and are developed by interacting with the outside world in the way that the function requires.
- Extroverted Thinking (Te)
- Extroverted Feeling (Fe)
- Extroverted Sensing (Se)
- Extroverted Intuition (Ne)
Perceiving Functions – Four of the functions are perceiving, and they gather information that is either physical stimuli or abstract concepts.
- Introverted Sensing (Si)
- Extroverted Sensing (Se)
- Introverted Intuition (Ni)
- Extroverted Intuition (Ne)
Judging Functions – Four of the functions are judging, and they organize information, either rationally or emotionally.
- Extroverted Thinking (Te)
- Introverted Thinking (Ti)
- Introverted Feeling (Fi)
- Extroverted Feeling (Fe)
Breaking them down even further:
Thinking Functions – logically and rationally organizes external world or internal thoughts
- Introverted Thinking (Ti)
- Extroverted Thinking (Te)
Feeling Functions – emotionally organizes external or internal feelings
- Introverted Feeling (Fi)
- Extroverted Feeling (Fe)
Sensing Functions – concerned with real world physical information, whether concrete experiences from the past or current real time experiences,
- Introverted Sensing (Si)
- Extroverted Sensing (Se)
Intuitive Functions – concerned with abstract information, may focus on current patterns and how they will affect the future
- Introverted Intuition (Ni)
- Extroverted Intuition (Ne)
So we add the final dimension:
