Hook Model Framework

Hook Model框架

Framework for building habit-forming products. Based on a fundamental truth: habits are not created—they are built through successive cycles through the Hook.

用于打造习惯养成类产品的框架。基于一个核心事实：习惯并非凭空产生——而是通过用户反复经历Hook循环逐步形成的。

Core Principle

核心原则

The Hook Model = a four-phase process that connects the user's problem to your solution frequently enough to form a habit.

Trigger → Action → Variable Reward → Investment
    ↑                                      │
    └──────────────────────────────────────┘

Habit Zone: Products enter the "habit zone" when used frequently enough and with enough perceived value. The goal is to move users from deliberate usage to automatic, habitual behavior.

Hook Model = 将用户的问题与你的解决方案频繁关联，从而形成习惯的四阶段流程。

Trigger → Action → Variable Reward → Investment
    ↑                                      │
    └──────────────────────────────────────┘

习惯区间（Habit Zone）： 当产品被用户足够频繁地使用，且能为用户带来足够的感知价值时，就进入了“习惯区间”。我们的目标是让用户从刻意使用转变为自动、习惯性的行为。

Scoring

评分机制

Goal: 10/10. When reviewing or creating product engagement mechanics, rate them 0-10 based on adherence to the principles below. A 10/10 means full alignment with all guidelines; lower scores indicate gaps to address. Always provide the current score and specific improvements needed to reach 10/10.

目标：10/10分。在评审或设计用户参与机制时，根据以下原则为其评分（0-10分）。10分表示完全符合所有准则，分数越低则说明存在需要改进的漏洞。需始终给出当前分数，以及具体的改进方向以达到10分。

The Four Phases

四个阶段

1. Trigger

1. 触发（Trigger）

The actuator of behavior. What prompts the user to take action?

Two types of triggers:

Type	Definition	Examples
External	Sensory stimuli in the environment	Push notification, email, button, ad, word of mouth
Internal	Internal cue, emotion, or routine	Boredom, loneliness, uncertainty, fear of missing out

The goal: Move users from external triggers (you prompt them) to internal triggers (they prompt themselves).

Mapping triggers to emotions:

Internal Trigger (Emotion)	Example Product
Boredom	Instagram, TikTok, YouTube
Loneliness	Facebook, Messaging apps
Uncertainty/FOMO	Twitter, News apps
Confusion	Google, Stack Overflow
Stress/Anxiety	Games, Meditation apps

See: references/triggers.md for detailed trigger design.

行为的启动器。是什么促使用户采取行动？

两种触发类型：

类型	定义	示例
外部触发	环境中的感官刺激	推送通知、邮件、按钮、广告、口碑传播
内部触发	内部的提示、情绪或日常惯例	无聊、孤独、不确定性、错失恐惧（FOMO）

目标： 让用户从外部触发（由产品主动提示）转变为内部触发（用户自我驱动）。

触发与情绪的对应关系：

内部触发（情绪）	示例产品
无聊	Instagram、TikTok、YouTube
孤独	Facebook、即时通讯应用
不确定性/错失恐惧（FOMO）	Twitter、新闻应用
困惑	Google、Stack Overflow
压力/焦虑	游戏、冥想应用

详见：references/triggers.md 中的触发机制设计细节。

2. Action

2. 行动（Action）

The simplest behavior done in anticipation of a reward.

Fogg Behavior Model:

B = MAT

Motivation: User wants to do it
Ability: User can easily do it
Trigger: User is prompted to do it

Six elements of simplicity (ability):

Element	Question	Example
Time	How long does it take?	Infinite scroll vs. page load
Money	What's the financial cost?	Free tier vs. paywall
Physical effort	How much work?	Voice input vs. typing
Brain cycles	How much thinking?	Autocomplete vs. blank field
Social deviance	Is it socially acceptable?	Anonymous vs. public
Non-routine	How unfamiliar?	Familiar patterns vs. new UI

Key insight: Increasing motivation is hard. Reducing friction is easier and often more effective.

Action formula:

Ease of action > User's motivation threshold

用户为了获得奖励而做出的最简单行为。

Fogg行为模型：

B = MAT

Motivation（动机）：用户想要完成该行为
Ability（能力）：用户能够轻松完成该行为
Trigger（触发）：用户收到行动提示

简化的六个要素（能力维度）：

要素	问题	示例
时间	完成行为需要多久？	无限滚动 vs 页面加载
金钱	财务成本是多少？	免费版 vs 付费墙
体力付出	需要多少工作量？	语音输入 vs 打字
脑力消耗	需要多少思考？	自动补全 vs 空白输入框
社交偏差	是否符合社会规范？	匿名模式 vs 公开模式
非常规性	陌生程度如何？	熟悉的交互模式 vs 全新UI

核心洞察： 提升用户动机难度较大，而降低行为阻力则更简单且通常更有效。

行动公式：

行动难度 < 用户动机阈值

3. Variable Reward

3. 可变奖励（Variable Reward）

The phase that keeps users coming back. The anticipation of reward (not the reward itself) creates dopamine.

Three types of variable rewards:

Type	Definition	Examples
Tribe	Social rewards from others	Likes, comments, followers, status
Hunt	Search for resources/information	Scrolling feeds, search results, deals
Self	Personal accomplishment	Leveling up, completion, mastery

Critical: Rewards must be variable. Predictable rewards lose power. The slot machine effect: uncertainty is addictive.

Autonomy: Users must feel in control. Forced engagement backfires.

See: references/rewards.md for reward design patterns.

让用户持续回访的阶段。对奖励的预期（而非奖励本身）会促使多巴胺分泌。

三种可变奖励类型：

类型	定义	示例
社群奖励（Tribe）	来自他人的社交奖励	点赞、评论、粉丝、身份地位
探索奖励（Hunt）	对资源/信息的搜索	滚动信息流、搜索结果、优惠活动
自我奖励（Self）	个人成就感	升级、完成目标、技能掌握

关键要点： 奖励必须具备可变性。可预测的奖励会逐渐失去吸引力。就像老虎机效应：不确定性会让人上瘾。

自主性： 用户必须感觉自己拥有控制权。强制的参与行为会产生反效果。

详见：references/rewards.md 中的奖励设计模式。

4. Investment

4. 投入（Investment）

The phase that increases the likelihood of another pass through the Hook.

Principle: Users value what they put effort into (IKEA effect). Investment creates switching costs.

Types of investment:

Investment	Example	Switching Cost
Data	Preferences, history, uploads	Loss of personalization
Content	Posts, playlists, documents	Loss of created work
Reputation	Reviews, ratings, followers	Loss of social proof
Skill	Learning the interface	Learning curve for alternatives
Social	Connections, groups	Losing relationships

Investment loads the next trigger:

Creating content → Notification when someone responds
Following users → Feed updates
Setting preferences → Personalized recommendations

提升用户再次进入Hook循环可能性的阶段。

原则： 用户会重视自己为之付出努力的事物（宜家效应，IKEA effect）。用户投入会产生转换成本。

投入类型：

投入类型	示例	转换成本
数据	偏好设置、历史记录、上传内容	个性化体验的损失
内容	帖子、播放列表、文档	原创内容的损失
声誉	评论、评分、粉丝	社交证明的损失
技能	学习产品界面操作	切换至竞品的学习曲线
社交关系	联系人、群组	人际关系的损失

投入会触发下一次循环：

创建内容 → 有人回复时收到通知
关注用户 → 信息流更新
设置偏好 → 个性化推荐

The Habit Zone

习惯区间（Habit Zone）

Two axes determine if a product can become a habit:

	Low Frequency	High Frequency
High Perceived Value	Viable product (needs ads/marketing)	HABIT ZONE
Low Perceived Value	Failure	Failure

Questions:

How often do users need to engage? (Daily, weekly, monthly?)
What's the perceived value of each engagement?
Is frequency high enough to form automatic behavior?

两个维度决定产品能否成为用户的习惯：

	低频率	高频率
高感知价值	可行产品（需要广告/营销支持）	习惯区间
低感知价值	失败产品	失败产品

思考问题：

用户需要多久使用一次产品？（每日、每周、每月？）
每次使用对用户的感知价值是什么？
使用频率是否足够高，能够形成自动行为？

Habit Testing

习惯测试

The 5% rule: A product has formed a habit when at least 5% of users show unprompted, habitual usage.

Three questions for habit testing:

Who are the habitual users?
- Which users engage most frequently?
- What do they have in common?
What are they doing?
- What's the "Habit Path" (common sequence of actions)?
- What differentiates power users from casual users?
Why are they doing it?
- What internal trigger drives the behavior?
- What emotion precedes usage?

See: references/habit-testing.md for testing methodology.

5%规则：当至少5%的用户表现出无提示的习惯性使用行为时，说明产品已成功让用户形成习惯。

习惯测试的三个问题：

谁是习惯性用户？
- 哪些用户的参与频率最高？
- 他们有哪些共同特征？
他们在做什么？
- 什么是“习惯路径”（常见的行为序列）？
- 核心用户与普通用户的行为差异是什么？
他们为什么这么做？
- 驱动行为的内部触发是什么？
- 使用产品前用户处于何种情绪状态？

详见：references/habit-testing.md 中的测试方法。

The Manipulation Matrix

操纵矩阵

Framework for evaluating the ethics of habit-forming products.

	Maker Uses Product	Maker Doesn't Use
Materially Improves User's Life	Facilitator ✓	Peddler ⚠️
Doesn't Improve Life	Entertainer	Dealer ✗

Questions to ask:

Would I use this product myself?
Does it genuinely help users achieve their goals?
Am I exploiting vulnerabilities or serving needs?

用于评估习惯养成类产品伦理合理性的框架。

	产品制造者自身使用该产品	产品制造者自身不使用该产品
切实改善用户生活	促进者 ✓	推销者 ⚠️
未改善用户生活	娱乐者	交易者 ✗

需要思考的问题：

我自己会使用这款产品吗？
它是否真的能帮助用户实现目标？
我是在利用用户的弱点，还是在满足用户的需求？

When NOT to Use the Hook Model

不适用于Hook Model的场景

The Hook Model is inappropriate when:

Your product doesn't genuinely improve lives
You're targeting vulnerable populations (children, addiction-prone users)
Business model depends on user regret
Engagement conflicts with user wellbeing

See ethical-boundaries.md for comprehensive ethics guidance.

当出现以下情况时，Hook Model并不适用：

你的产品无法切实改善用户生活
目标用户是弱势群体（儿童、易成瘾人群）
商业模式依赖用户的后悔情绪
用户参与行为与用户福祉相冲突

详见 ethical-boundaries.md 中的全面伦理指导。

Regulatory Context

监管环境

Be aware of emerging regulations around:

Children's apps: COPPA, GDPR-K restrictions
Dark patterns: FTC enforcement increasing
Notification practices: Some jurisdictions regulating "addictive" features
Loot boxes: Gaming regulations expanding

需关注以下新兴监管政策：

儿童应用： COPPA、GDPR-K相关限制
暗黑模式： FTC的执法力度正在加强
通知规范： 部分地区对“成瘾性”功能进行监管
开箱机制： 游戏相关监管正在扩大

Onboarding Audit Checklist

新用户引导审核清单

Optimizing onboarding for habit formation:

优化新用户引导流程以促进习惯养成：

First Trigger

首次触发

Is the first action obvious and easy?
Is the value proposition clear before asking for investment?
Are we using the right external trigger for this user?

首次行动是否清晰易懂且易于完成？
在要求用户投入前，是否已清晰传达产品价值主张？
是否针对该用户采用了合适的外部触发方式？

First Action

首次行动

Can the user complete the core action in under 60 seconds?
Have we removed all unnecessary friction?
Is the UI familiar (not requiring new learning)?

用户能否在60秒内完成核心行动？
是否已移除所有不必要的阻力？
UI是否符合用户使用习惯（无需学习新操作）？

First Reward

首次奖励

Does the user get immediate feedback?
Is there a variable element (surprise, delight)?
Does the reward connect to an internal trigger?

用户能否获得即时反馈？
是否包含可变元素（惊喜、愉悦感）？
奖励是否与内部触发相关联？

First Investment

首次投入

Do we ask for investment after reward (not before)?
Is the investment small but meaningful?
Does the investment load the next trigger?

是否在用户获得奖励后再要求投入（而非之前）？
投入是否微小但有意义？
投入是否为下一次触发做好了准备？

Loop Completion

循环完成

Is there a clear path back to the trigger?
Do we send external triggers at appropriate times?
Are we measuring progression through the Hook?

是否有清晰的路径回到触发环节？
是否在合适的时间发送外部触发？
是否在跟踪用户在Hook循环中的进展？

Quick Diagnostic

快速诊断

Audit any product feature:

Question	If No	Action
What's the internal trigger?	Users need reminders to use it	Research user emotions
Is the action dead simple?	Users start but don't complete	Remove friction
Is the reward variable?	Users get bored	Add unpredictability
Does investment load next trigger?	Users don't return	Connect investment to triggers

对任意产品功能进行审核：

问题	如果答案为否	行动
内部触发是什么？	用户需要被提醒才会使用产品	研究用户的情绪驱动因素
行动是否足够简单？	用户开始行动但无法完成	降低行为阻力
奖励是否具备可变性？	用户感到厌倦	增加不可预测性
投入是否会触发下一次循环？	用户不再回访	将用户投入与触发机制关联

Warning Signs

预警信号

Your habit loop is broken if:

Users need constant external triggers (they're not forming habits)
Engagement drops after novelty wears off (weak reward)
Users don't increase usage over time (no investment)
High churn despite initial engagement (wrong internal trigger)
Users describe product as "useful but forgettable"

如果出现以下情况，说明你的习惯循环存在问题：

用户需要持续的外部触发（尚未形成习惯）
新鲜感过后用户参与度下降（奖励机制薄弱）
用户使用频率未随时间提升（缺乏用户投入）
初始参与度高但流失率高（内部触发匹配错误）
用户评价产品“有用但容易忘记使用”
