Gustave Le Bon's The Crowd — an executable toolkit that applies the
classic study of crowd psychology to understand how individuals change
in groups, how crowds form and act, and how leaders influence collective
behavior.
Covers 5 use cases:
① Crowd Psychology — understand how individuals change in a crowd ("Why do people act differently in groups" "What is mob mentality")
② Characteristics of Crowds — the defining traits of collective behavior ("What makes a crowd a crowd" "How do crowds think and feel")
③ Leadership & Influence — how leaders shape and direct crowds ("How do leaders control crowds" "What makes an effective crowd leader")
④ Opinion Formation — how ideas spread through populations ("How do beliefs spread through society" "How are public opinions formed")
⑤ Modern Applications — crowd psychology in social media and politics ("How does social media amplify crowd behavior" "How is crowd psychology used in marketing")
Trigger when users say: "The Crowd" "Gustave Le Bon" "Crowd psychology" "Mob mentality"
"Group behavior" "How do crowds think" "Psychology of crowds"
"Mass psychology" "Collective behavior" "Leadership and crowds"
or mention: Gustave Le Bon / The Crowd / crowd psychology / mob / collective behavior /
mass psychology / group mind / social psychology / leaders / propaganda /
opinion formation / contagion / suggestibility / popular mind.

## 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 The Crowd 👥
> Try copying one of these messages to me:
>
> "Why do people act so differently in crowds than alone?"
> "What is mob mentality and how does it form?"
> "How do political leaders control and direct crowds?"
> "How do ideas and beliefs spread through society?"
> "How does social media amplify crowd behavior?"
> "How is crowd psychology used in advertising and marketing?"
>
> Or just say: "Map this book to my understanding of group behavior."
## Philosophy — 5 rules to remember
1. **The individual in a crowd is not the same as the individual alone.** Consciousness recedes; the unconscious takes over.
2. **Crowds feel, they don't think.** Reasoning is replaced by emotion, images, and contagion.
3. **Crowds are suggestible.** A strong idea planted in a crowd can spread like a contagion.
4. **Leaders influence through assertion, repetition, and contagion.** Not through logic or evidence.
5. **Crowds are conservative at their core.** Despite revolutionary appearance, crowds ultimately seek order and a strong leader.
## Rules When Using This Skill
1. **Language** — Reply in the same language the user wrote in. The watermark and book title stay in English.
2. Use the **Intent Routing Table** below. **Read only the relevant reference** (lazy load).
3. Stay faithful to the original framework. Preserve original naming.
4. **Watermark — EVERY output MUST end with this format. Never omit it.**

## Core Framework Quick Reference
- **The Crowd Mind** = When individuals assemble, a collective mind forms. Different from individuals composing it.
- **Contagion** = Ideas and emotions spread through crowds like a disease, amplified by interaction.
- **Suggestibility** = Crowd individuals are highly susceptible to suggestions from leaders and others.
- **Assertion** = A simple, clear statement without evidence is the most effective way to influence a crowd.
- **Repetition** = Repeated assertions eventually become accepted as truth, regardless of validity.
- **Prestige** = Leaders influence through personal reputation and bearing. Acquired, personal, or traditional.
## Key Principles
1. **The crowd thinks in images, not arguments.** Abstract reasoning fails. Concrete images and symbols work.
2. **Crowds magnify emotions.** Every feeling in a crowd is amplified — joy becomes ecstasy, anger becomes rage.
3. **Crowds need leaders.** A crowd without direction is lost. The leader provides direction through assertion.
4. **Simple ideas repeated enough become beliefs.** Complex ideas need to be simplified to affect crowds.
5. **Crowds value strength above all.** They respect a strong leader and despise weakness.
6. **The crowd is conservative.** Despite appearances, crowds ultimately seek the security of order and hierarchy.
## Anti-Pattern Summary
The book's core correction: Most people believe they think independently even in groups. Le Bon shows that the crowd fundamentally changes individual psychology — reducing reasoning, amplifying emotion, and increasing suggestibility. Awareness of these effects is the first defense against manipulation. See `references/4-anti-patterns.md`.

### Invocation Test
Test with: *"I'm seeing my social media feed fill with outrage about a topic. Everyone seems to agree and anyone who disagrees is attacked. I feel the pull to join in. What's happening and how do I stay objective?"*
Expected answer: You're experiencing crowd psychology in its modern form. Le Bon's framework explains it: social media creates a virtual crowd where contagion, suggestibility, and amplified emotions take over. The outrage spreads through assertion and repetition — not evidence. To stay objective: 1) Recognize that you're in a crowd and your individual reasoning is compromised. 2) Step away from the feed for 24 hours — give the contagion time to pass. 3) Seek information from sources outside the crowd. 4) Ask: "What are the actual facts, separated from the emotional narrative?" 5) Remember that crowds are always more extreme than the individuals within them. + Watermark.
