# Nir Eyal ![[50 Resources/51 Attachments/51.03 Public/2026-05-04 Nir Eyal.jpg|400]] Nir Eyal (born 1980) is an Israeli-American author, consultant, and lecturer known for his work on behavioral design, habit formation, and attention management. His 2014 book *[[Hooked (book)|Hooked: How to Build Habit-Forming Products]]* became a Silicon Valley bible for product designers, introducing the **Hook Model**—a four-phase cycle (trigger → action → variable reward → investment) that explains how products create user habits. The book drew from psychology research by [[B. F. Skinner]], behavioral economics, and Eyal's own experience in gaming and advertising. Eyal taught at Stanford's Graduate School of Business and has consulted for companies including Google, Microsoft, and PayPal. His follow-up book *Indistractable: How to Control Your Attention and Choose Your Life* (2019) addresses the flip side of habit-forming design—how individuals can resist unwanted distractions. This evolution reflects broader debates about technology ethics: Eyal first taught companies to capture attention, then taught individuals to reclaim it. His work sits at the intersection of [[Behavioral Economics]], persuasive technology, and [[Product Design]], raising ongoing questions about the responsibility of designers who exploit psychological vulnerabilities. ## The Hook Model ``` ┌─────────────────────────────────────────────────────────────┐ │ THE HOOK MODEL │ │ (Nir Eyal, 2014) │ ├─────────────────────────────────────────────────────────────┤ │ │ │ ┌──────────┐ │ │ ┌─────▶│ TRIGGER │◀─────┐ │ │ │ └────┬─────┘ │ │ │ │ │ │ │ │ │ ▼ │ │ │ ┌────────┴───┐ ┌──────────┐ │ │ │ │ INVESTMENT │ │ ACTION │ │ │ │ └────────────┘ └────┬─────┘ │ │ │ ▲ │ │ │ │ │ ▼ │ │ │ │ ┌───────────┐ │ │ │ └────┤ VARIABLE │───────┘ │ │ │ REWARD │ │ │ └───────────┘ │ │ │ │ The cycle repeats, each pass strengthening the habit │ │ │ └─────────────────────────────────────────────────────────────┘ ``` ## Hook Model Phases | Phase | Description | Example (Instagram) | |-------|-------------|---------------------| | **Trigger** | External or internal cue | Notification, boredom | | **Action** | Simplest behavior in anticipation of reward | Open app, scroll | | **Variable Reward** | Unpredictable positive reinforcement | New likes, interesting posts | | **Investment** | User puts something in (time, data, effort) | Post photo, follow accounts | ## Types of Triggers | Type | Description | Example | |------|-------------|---------| | **External** | Environmental cues | Push notification, email | | **Internal** | Emotional states | Boredom, loneliness, FOMO | | **Paid** | Advertising | Facebook ads | | **Earned** | PR, viral content | Press coverage | | **Relationship** | Word of mouth | Friend recommendation | | **Owned** | User-consented | App icon, email subscription | ## Types of Variable Rewards | Type | Description | Example | |------|-------------|---------| | **Tribe** | Social rewards | Likes, comments, followers | | **Hunt** | Search for resources | Scrolling feeds, deals | | **Self** | Mastery, completion | Leveling up, achievements | ## Key Contributions | Contribution | Year | Significance | |--------------|------|--------------| | **Hooked** | 2014 | Habit-forming product design | | **Hook Model** | 2014 | Framework for engagement | | **Indistractable** | 2019 | Attention management | | **Manipulation Matrix** | 2014 | Ethics framework | ## Manipulation Matrix | | User Benefits | User Doesn't Benefit | |---|---|---| | **Maker Uses Product** | Facilitator | Entertainer | | **Maker Doesn't Use** | Peddler | Dealer | ## Career Timeline | Period | Activity | |--------|----------| | 2000s | Founded/sold two tech companies | | 2008-2012 | Intersection of gaming and advertising | | 2012-2014 | Taught at Stanford GSB | | 2014 | *Hooked* published | | 2019 | *Indistractable* published | | Ongoing | Consulting, speaking, writing | ## Indistractable Framework | Concept | Description | |---------|-------------| | **Traction** | Actions toward your goals | | **Distraction** | Actions away from goals | | **Internal triggers** | Master discomfort driving distraction | | **External triggers** | Hack back unwanted interruptions | | **Timeboxing** | Schedule your values | | **Pacts** | Precommitment devices | ## Influences and Foundations | Source | Concept | |--------|---------| | [[B.F.
