## Part 1: The Four Dichotomies

The foundation of the 16-type system is built on four pairs of opposing preferences, known as dichotomies.

-   **Energy:** Introversion (I) vs. Extraversion (E)
    -   *Where do you get your energy?*
-   **Information:** Sensing (S) vs. Intuition (N)
    -   *What kind of information do you naturally notice?*
-   **Decisions:** Thinking (T) vs. Feeling (F)
    -   *How do you make decisions?*
-   **Lifestyle:** Judging (J) vs. Perceiving (P)
    -   *How do you prefer to live your outer life?*

## Part 2: The 16 Personality Types

The combination of the four dichotomies results in 16 distinct personality types. Each type has a unique "stack" of cognitive functions that dictates how they perceive the world and make decisions.

*(This section can be expanded with descriptions for each of the 16 types.)*

-   ISTJ
-   ISFJ
-   INFJ
-   INTJ
-   ISTP
-   ISFP
-   INFP
-   INTP
-   ESTP
-   ESFP
-   ENFP
-   ENTP
-   ESTJ
-   ESFJ
-   ENFJ
-   ENTJ

## Part 3: The Cognitive Functions

The cognitive functions are the "mental software" that underpins the four-letter type code. Each type has a stack of four primary functions, ordered by strength and consciousness.

### The 8 Functions

**Perceiving Functions (Information Gathering):**
-   **Introverted Sensing (Si):** Internal library of past experiences and detailed facts.
-   **Extraverted Sensing (Se):** Focus on the current, tangible, sensory world.
-   **Introverted Intuition (Ni):** Synthesizing patterns to form a singular, future-oriented vision.
-   **Extraverted Intuition (Ne):** Exploring possibilities, connections, and what-ifs in the external world.

**Judging Functions (Decision Making):**
-   **Introverted Thinking (Ti):** Internal framework of logic and first principles.
-   **Extraverted Thinking (Te):** Organizing the external world for efficiency and logic.
-   **Introverted Feeling (Fi):** Internal compass of personal values and authenticity.
-   **Extraverted Feeling (Fe):** Focus on social harmony and the values of the group.
