Fable

Fable

Overview

Explain graduate-level, counterintuitive concepts through metaphorical fable stories. The story embodies the concept's underlying structure without naming it, creating an "aha moment" when the concept is revealed at the end.

When to Use

• User wants to deeply understand a complex academic concept
• User specifies a domain like "计算机科学", "经济学", "哲学" and wants to learn
• User asks for an intuitive explanation of something abstract or counterintuitive
• User explicitly invokes /fable or asks to "用寓言解释"

Workflow

Step 1: Select the Concept

If user provided a specific concept name, use it directly. Otherwise:

1. From the specified domain, identify a graduate-level concept that is complex and counterintuitive.
2. The concept should be non-trivial — something that challenges intuition and requires deep understanding.
3. Briefly confirm with the user: "我选择的概念是 [概念名]，可以吗？"

Examples of good concept choices by domain:

• 计算机科学: CAP 定理、拜占庭将军问题、PAC 学习理论、停机问题
• 经济学: 比较优势、公地悲剧、柠檬市场、科斯定理
• 哲学: 缸中之脑、忒修斯之船、中文房间、囚徒困境
• 物理学: 量子纠缠、双缝实验、麦克斯韦妖、熵增原理
• 数学: 哥德尔不完备定理、蒙提霍尔问题、巴拿赫-塔斯基悖论
• 生物学: 红皇后假说、自私的基因、生态位构建

Step 2: Write the Fable (500-1000 characters)

Craft a narrative story that:

Core Rules:

• The story's entire plotline and structure MUST perfectly embody the concept's underlying mechanism
• NEVER name the concept in the story — no hints, no technical terms, no direct references
• The reader should NOT immediately guess what concept it is

Story Structure:

• Beginning: Set up characters and a situation that mirrors the concept's premises
• Middle: Develop the plot — this is where the concept's mechanism plays out
• End: Reach a conclusion or revelation that aligns with the concept's implications
• The "aha moment" should come near the end, not at the beginning

Language Adaptation (by audience):

• Adapt vocabulary, sentence length, and metaphor domain to the target audience
• For children: use animals, toys, daily objects as characters
• For adults: use workplace scenarios, social dynamics, technology
• For professionals: can use domain-appropriate scenarios as metaphor vehicles

Quality Check:

• After writing, verify: if a reader knows the concept, would they immediately recognize it? If yes, rewrite to make the metaphor more indirect.
• The fable should stand alone as a good story even without the reveal.

Step 3: The Reveal — Name and Explain

After the fable ends, clearly separate with a divider and:

1. Formally name the concept
2. Explain it in clear, accurate terms appropriate to the audience level
3. Explain WHY it is counterintuitive — what makes it graduate-level
4. Keep the explanation concise but complete

Step 4: Mapping — Connect Story to Concept

Break down the correspondence between story elements and concept components:

For each key element in the story (character, event, setting, object), map it to:

• What it represents in the real concept
• Why this mapping is apt

Use a clear format like a table or numbered list. Example:

Example

User input: /fable 计算机科学

AI selects concept: CAP 定理

Fable (abbreviated):

在一个王国里，老国王年迈体衰，他把国家分给了三个儿子管理。但他定下一条铁律：任何决策，三个儿子必须意见一致才能执行。起初一切顺利，但后来一场暴风雪切断了三兄弟之间的通信...

大哥面临一个抉择：要么等通信恢复（但子民在挨饿），要么自己做决定（但违背父王的铁律），要么听任二弟三弟各自为政（但国家会分裂）...

Reveal: 这就是 CAP 定理——分布式系统中，一致性（Consistency）、可用性（Availability）、分区容错性（Partition Tolerance）三者不可兼得。

Mapping: 老国王=理想状态，三兄弟=三个节点，暴风雪=网络分区，铁律=强一致性...
