Key Concepts Introduced by the Book
1. The Hook Model
Eyal’s core framework consists of four steps:
Trigger: External or internal cues that prompt user action. External triggers include notifications or ads, while internal triggers are emotional drivers like boredom or anxiety.
Action: The simplest behavior performed in anticipation of a reward. Eyal emphasizes reducing friction to encourage user action.
Variable Reward: Unpredictable rewards that satisfy users’ desires while keeping them engaged, such as likes on social media or a new level in a game.
Investment: Users commit effort, time, or resources, increasing their attachment to the product and making them more likely to return.
2. Building User Habits
The book highlights how successful products leverage users’ internal triggers and seamlessly integrate into their routines, since
“The most successful products don’t just attract users; they create habits.”
Eyal explains how small investments, such as creating a profile or saving preferences, increase user retention.
3. The Role of Variable Rewards
Eyal explores the psychology behind variable rewards, explaining why unpredictability enhances engagement. He categorizes rewards into three types:
Rewards of the Tribe (social validation)
Rewards of the Hunt (material rewards)
Rewards of the Self (intrinsic satisfaction)
4. Behavioral Design
The book provides actionable advice for reducing friction and making desired actions as easy as possible. Eyal also discusses the importance of understanding user psychology to align product design with users’ needs and motivations.
5. Ethical Design
Eyal dedicates a chapter to ethical considerations, urging creators to build products that enhance users’ lives rather than exploiting vulnerabilities.

“The Hook model is not a one-time event; it’s an infinite loop designed to keep users coming back.”
3. Optimizing User Experience
