Resumen

Design habit-forming product loops using the Hook Model (Trigger, Action, Variable Reward, Investment). Use when the user mentions "users arent coming back", "habit formation", "engagement loops", "habit zone", or "the manipulation matrix". Also trigger when designing notification or re-engagement strategies, building streaks or progress systems, or analyzing why users stop after signup. Covers ethics evaluation and onboarding for habits. For friction reduction and B=MAP, see improve-retention. For viral sharing, see contagious.

Hook Model Framework

Framework for building habit-forming products. Habits are not created — they are built through successive cycles through the Hook.

Core Principle

The Hook Model = a four-phase loop that connects the user's problem to your solution frequently enough to form a habit, moving usage from deliberate to automatic.

Trigger → Action → Variable Reward → Investment

Scoring

Goal: 10/10. When reviewing or creating product engagement mechanics, score the loop by the four Quick Diagnostic rows (internal trigger, dead-simple action, variable reward, investment loads next trigger): each row earns 2 (fully satisfied), 1 (partial), or 0 (absent), then score = round(total / 8 × 10). Then apply the ethics gate: if the Manipulation Matrix places the product as Dealer (or it hits any "When NOT to Use" condition), cap the score at 3 regardless of mechanics. Bands: 9-10 = complete loop, internal trigger identified, ethics clear; 5-6 = loop runs but leans on external triggers or predictable rewards; <=3 = broken loop or extractive design. Always state the current score and the specific diagnostic rows blocking 10/10.

The Four Phases

1. Trigger

Core concept: The actuator of behavior. Triggers are external (environment-driven: notifications, emails, ads) or internal (emotion-driven) — and the goal is to migrate users from external to internal triggers.

Why it works: Every habit starts with a cue. External triggers get users started, but internal triggers — boredom, loneliness, uncertainty, FOMO — drive unprompted usage because the emotion itself fires before any reminder can.

Key insights:

Map your product to the specific negative emotion it resolves (boredom, loneliness, confusion, FOMO)
Effective external triggers are well-timed, actionable, and lead to the simplest possible next action
If users still need external prompts after ~30 days, no internal trigger has formed

Product applications:

Context	Application	Example
Onboarding	External triggers establish the first loop	Welcome email with one clear action
Retention	Map product to internal emotional trigger	Instagram resolves boredom; Google resolves confusion
Re-engagement	External triggers bridge gaps until habit forms	Push: "Your friend just posted a photo"

Copy patterns:

"Don't miss what happened while you were away" (FOMO trigger)
"Your friend just..." (social trigger bridging to internal)
"Pick up where you left off" (routine trigger)

Ethical boundary: Don't build triggers that fire on vulnerable emotional states (depression, addiction, grief) — those users can't exercise the autonomy the loop assumes.

See references/triggers.md when mapping triggers — the emotion-to-product mapping exercise and the external-to-internal transition plan.

2. Action

Core concept: The simplest behavior done in anticipation of a reward, guided by the Fogg Behavior Model: Behavior = Motivation + Ability + Trigger, all converging at the same moment.

Why it works: Increasing motivation is hard and unreliable; reducing friction (increasing ability) is easier and more effective. Every extra step, field, or decision is a drop-off point.

Key insights:

Six elements of simplicity: time, money, physical effort, brain cycles, social deviance, non-routine
The action is the simplest behavior in anticipation of reward — not the full task
Hick's Law: more choices = slower decisions; reduce options to increase action rate

Product applications:

Context	Application	Example
Signup flow	Minimize fields and steps	One-click Google/Apple sign-in
Core action	Completable in seconds	Twitter: type 280 characters and post
Progressive disclosure	Ask for more only after initial reward	Duolingo: play first, create account later

Copy patterns:

"Just one tap to..." (emphasizes simplicity)
"No credit card required" (money/risk simplicity)
Buttons should be verbs: "Post", "Save", "Share" — not "Submit" or "Continue"

Ethical boundary: When you simplify an action, don't strip the cost or consequence with it — a one-tap purchase must still surface the price and the commitment.

See references/product-applications.md when adapting the loop to your context — action and investment patterns for B2B SaaS, e-commerce, health, and productivity tools.

3. Variable Reward

Core concept: The phase that keeps users coming back. Anticipation of reward — not the reward itself — creates dopamine, and rewards must be variable (unpredictable) to sustain engagement.

Why it works: The brain's dopamine system responds most strongly to anticipation of uncertain rewards — the slot machine effect. Three reward types — tribe (social), hunt (resources), self (mastery) — tap fundamental human drives.

Key insights:

Tribe = social validation; Hunt = search for resources/information; Self = personal mastery
Predictable rewards lose power; finite variability eventually becomes predictable — aim for infinite variability
Autonomy is critical: users must feel in control; forced engagement backfires

Product applications:

Context	Application	Example
Social features (Tribe)	Variable social validation	Instagram likes — you never know how many
Content feeds (Hunt)	Unpredictable resource stream	Infinite scroll with algorithmically varied content
Gamification (Self)	Accomplishment with variable difficulty	Duolingo streaks + surprise bonus challenges

Copy patterns:

"See what's new" (implies variability)
"3 people responded to your post" (tribe reward, variable quantity)
"You've unlocked a new achievement!" (self reward, unexpected)

Ethical boundary: If users consistently feel worse after engaging (regret, time loss, anxiety), the reward system is extractive — avoid infinite scroll without natural stopping points.

See references/rewards.md when designing a reward — tribe/hunt/self patterns, the four reinforcement schedules, and reward timing. For the dopamine/anticipation mechanism behind variable rewards, see references/neuroscience-foundations.md.

4. Investment

Core concept: Users invest something — time, data, effort, social capital, money — that improves the product for next use, raises switching costs, and loads the next trigger.

Why it works: People value what they put effort into (the IKEA effect). Investment is not about immediate reward — it improves the next cycle, creating a self-reinforcing loop.

Key insights:

Investment should come after reward, not before — users invest when they feel good
Each investment should load the next trigger (posting content triggers reply notifications)
Small investments compound: preferences → better recommendations → more usage; stored value grows over time

Product applications:

Context	Application	Example
Data investment	History improves personalization	Spotify: more listening = better recommendations
Content investment	User-created content they won't abandon	Instagram posts, Notion documents
Reputation/social investment	Social capital that exists only on-platform	Airbnb host ratings, LinkedIn network

Copy patterns:

"Complete your profile to get better matches" (investment → future value)
"The more you use it, the smarter it gets" (compound investment)
"Invite your team to collaborate" (social investment)

Ethical boundary: Investment should genuinely improve the experience — never trap users with artificial switching costs or impossible data export; make staying the better choice through real value.

The 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

Ask: how often do users need to engage, what's the perceived value of each engagement, and is frequency high enough to form automatic behavior?

Habit Testing

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

Three questions:

Who are the habitual users? Which users engage most frequently, and what do they share?
What are they doing? Identify the "Habit Path" — the action sequence that separates power users from casual users.
Why are they doing it? What internal trigger and emotion precede usage?

See references/habit-testing.md when running the test — cohort analysis, finding the Habit Path, and confirming the 5% threshold. For worked teardowns of these loops in real products (Instagram, Slack, Duolingo, Pinterest, and failures), see references/case-studies.md.

The Manipulation Matrix

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

Ask: would I use this myself? Does it genuinely help users achieve their goals? Am I exploiting vulnerabilities or serving needs?

When NOT to Use the Hook Model

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

See references/ethical-boundaries.md when the Manipulation Matrix flags a concern — dark-pattern catalog and how to protect vulnerable users.

Regulatory Context

Watch emerging regulation: children's apps (COPPA, GDPR-K), dark patterns (rising FTC enforcement), "addictive" notification practices, and loot boxes (expanding gaming rules).

Onboarding Audit Checklist

Optimizing onboarding for habit formation:

First Trigger

First action obvious and easy; right external trigger for this user
Value proposition clear before asking for investment

First Action

Core action completable in under 60 seconds, friction removed
UI familiar (no new learning required)

First Reward

Immediate feedback with a variable element (surprise, delight)
Reward connects to an internal trigger

First Investment

Investment asked after reward (not before), small but meaningful
Investment loads the next trigger

Loop Completion

Clear path back to the trigger; external triggers sent at appropriate times
Progression through the Hook is measured

Common Mistakes

Mistake	Why It Fails	Fix
Relying on external triggers indefinitely	You're renting attention, not building habits	Map product to an emotion;
