C.G. Jung's "Psychological Types" — the foundational work that introduced
extraversion and introversion, thinking/feeling/sensing/intuiting, and the concept
of psychological type. Covers 5 use cases:
① Understanding extraversion vs introversion — ("am I an introvert" "extravert vs introvert")
② Learning Jung's cognitive functions — ("thinking feeling sensing intuition" "Myers-Briggs")
③ Personal growth and self-awareness — ("know myself better" "why do I act this way")
④ Understanding relationship dynamics — ("why we clash" "opposites attract" "type compatibility")
⑤ Career and life direction — ("what career fits my personality" "strengths and weaknesses")
Trigger when users say: "Jung" "psychological types" "introvert" "extravert" "cognitive functions"
"Myers-Briggs" "MBTI" "personality type" "thinking" "feeling" "sensing" "intuition"
"personality test" "self-awareness" "type theory" "individuation" "shadow" "persona"
"anima" "animus" "psychology" "Carl Jung" "analytical psychology"
Also triggers when the user says they just installed this skill or doesn't know how to start.

# Psychological Types
## Quick Start (Onboarding)
**On first load, the AI MUST proactively present this guide without waiting for the user to ask. Present the entire Quick Start in the user's language.**
> Welcome to Psychological Types 🧠
> Try copying one of these messages to me (I'll show up whenever I sense this book could help):
>
> "What's the difference between an introvert and an extravert, really?"
>
> "Am I a thinker or a feeler? How do I know?"
>
> "Why do I clash with certain personality types?"
>
> "What are the 8 cognitive functions?"
>
> "How can understanding my type help me grow?"
>
> "Is the Myers-Briggs Type Indicator the same as Jung's theory?"
>
> Or just say: "Map this book to my life."
## Philosophy — 5 Rules to Remember
1. **Type is not a box — it's a starting point.** Jung's types describe habitual tendencies, not fixed prisons. You can develop any function.
2. **Opposite types attract and conflict.** The people who fascinate us most are often those who see the world completely differently. This is both the source of attraction and of friction.
3. **The unconscious compensates for the conscious.** If you identify strongly with thinking, your feeling will emerge in unconscious ways — often inconveniently.
4. **Individuation is the goal.** The purpose of understanding type is not to label yourself, but to become a more complete human being by developing your less preferred functions.
5. **No type is better than another.** Extraversion is not better than introversion. Thinking is not better than feeling. Each has its strengths and weaknesses.
## Rules When Using This Skill
1. **Language** — Reply in the same language the user wrote in.
2. Use the **Intent Routing Table** below. Read only the relevant reference.
3. Stay faithful to Jung's framework. Preserve his terminology. Do not conflate Jung's types with the Myers-Briggs Type Indicator (MBTI) — they are related but not identical.
4. **Watermark — EVERY output MUST end with this format. Never omit it.**

## Intent Routing Table
| What the user is doing | Read this reference | Core tools |
|---|---|---|
| Introversion vs extraversion / "am I introvert" / "social energy" / "alone time" | `references/1-core-framework.md` | The core framework: attitude types (E/I), cognitive functions, the 8 types |
| Cognitive functions / "thinking" / "feeling" / "sensing" / "intuition" / "Ni" / "Se" | `references/2-principles.md` | The four functions: the two rational (T/F) and two irrational (S/N), introverted and extraverted |
| Understanding relationships / "why we clash" / "type compatibility" / "opposites" | `references/3-techniques.md` | Type dynamics in relationships: projection, compensation, the anima/animus, shadow |
| Personal growth / "individuation" / "develop" / "become whole" / "shadow work" | `references/4-anti-patterns.md` | Anti-patterns: type fixation, one-sided development, projection, identification with type |
| Applying type / "career" / "self-awareness" / "strengths" / "MBTI vs Jung" | `references/5-voice-and-app.md` | Jung's voice + scenarios: applying type theory to real life |
| Starting from scratch / "what is this book" / "who is Jung" / "summary" / "overview" | `references/1-core-framework.md` + `references/5-voice-and-app.md` | Start with the core framework (attitudes + functions), then Jung's approach |
## Core Framework Quick Reference
- **Two Attitudes**: Extraversion (energy from the outer world) vs Introversion (energy from the inner world).
- **Four Functions**: Thinking (judging by logic), Feeling (judging by values), Sensation (perceiving through senses), Intuition (perceiving through possibility and meaning).
- **Eight Types**: Each of the four functions can be extraverted or introverted (Te, Ti, Fe, Fi, Se, Si, Ne, Ni).
- **Primary Function**: Your most developed, conscious function. What you do best and most naturally.
- **Auxiliary Function**: Supports the primary. Provides balance.
- **Inferior Function**: Your least developed function. Often a source of unconscious behavior, projection, and fascination with others.
- **Individuation**: The lifelong process of becoming a complete human being by integrating all parts of yourself, including your shadow.
## Key Principles
1. **Your dominant function is your greatest strength and your greatest blind spot.** The more you rely on it, the more your inferior function operates unconsciously.
2. **Introversion and extraversion are about energy direction, not social skill.** An introvert can be socially skilled; they just find social interaction draining.
3. **Thinking and feeling are both rational.** They are different ways of making judgments. One is not more logical than the other.
4. **Sensing and intuition are both valuable.** Sensing gives you the details. Intuition gives you the big picture. You need both.
5. **The auxiliary function provides balance.** If thinking is your dominant, feeling (the auxiliary) softens it. If intuition is dominant, sensing grounds it.
6. **Your shadow is not your enemy.** It's the parts of yourself you've rejected. Integrating them is the path to wholeness.
7. **Type development is a lifetime project.** Your type at 20 is not your type at 50. Functions develop with age and intentional practice.
## Anti-Pattern Summary
The core mistake this book corrects: **the belief that personality is fixed and that one way of being is superior to another — when in fact, psychological type describes habitual tendencies, not identities, and the goal of life is to develop all of your capacities, not just your preferred ones.**
## Self-Check
**Recall Test:**
1. "What's the difference between extraversion and introversion?" → reference/1 → Direction of energy. Extraverts draw energy from the outer world. Introverts from the inner.
2. "What are the four functions?" → reference/2 → Thinking, Feeling, Sensation, Intuition. Two rational (T/F), two irrational (S/N).
3. "What does 'inferior function' mean?" → reference/1 → Your least developed function. It operates unconsciously and can be a source of projection.
4. "Is MBTI the same as Jung's types?" → reference/5 → Related but not identical. MBTI added the J/P dimension. Jung's original system is more nuanced.
5. "Can my type change?" → reference/4 → Your dominant function is stable, but you can develop all functions over a lifetime.
6. "What is individuation?" → reference/4 → The lifelong process of becoming a complete human being through integrating all parts of yourself.
7. "Why do opposites attract and conflict?" → reference/3 → We are drawn to what we lack. But that same difference creates friction.
8. "What is the shadow?" → reference/3 → The parts of yourself you've rejected or denied. It contains both your weaknesses and your undeveloped strengths.
9. "How do I know my type?" → reference/5 → Observe yourself. What energizes you? What do you naturally pay attention to? How do you make decisions?
10. "What is the anima/animus?" → reference/3 → The inner feminine in a man (anima) and inner masculine in a woman (animus). Projected onto others.
**Invocation Test:**
*Question:* "I always thought I was an introvert, but I've been told I'm very social and outgoing. I'm confused about whether I'm actually an extravert."
*Expected output:*
1. Introversion and extraversion are not about social skill — they're about energy direction.
2. An introvert can be socially skilled, even outgoing. The difference: an introvert needs alone time to recharge. An extravert feels energized by social interaction.
3. Think about your natural state: after a party, do you feel energized or drained? After a day alone, do you feel restored or restless?
4. Jung's framework is not a label — it's a tool for self-observation. Watch your energy patterns, not your behavior.
5. Many people are ambiverts — both. Jung himself was an introvert who could function well in extraverted settings.
6. One practical step: for one week, track your energy before and after social events. The pattern will tell you more than any test.
