Hooked: A Summary of Nir Eyal's Insights on Addiction

Bookey En(Book Review and Notes)

Chapter 1 What's Hooked

"Hooked: How to Build Habit-Forming Products" is a book by Nir Eyal, with contributions from Ryan Hoover, the founder of Product Hunt. Published in 2014, the book explores the psychology behind why certain products are addictive and how companies can create habit-forming products that keep users engaged.
The central framework Eyal presents in the book is known as the "Hook Model," which consists of four key components that influence user behavior:
1. Trigger: A trigger prompts the user to take action. Triggers can be external (such as notifications or advertisements) or internal (emotional states that drive users to use the product).
2. Action: This is the behavior that users take in anticipation of a reward. The action should be simple and achievable.
3. Variable Reward: The user receives a reward for completing the action, but it is variable and not predictable, which keeps users engaged and curious about what they might receive next.
4. Investment: This phase involves the user investing time, effort, or resources into the product, which increases the likelihood that they will return in the future. Investments can lead to a better user experience or more significant rewards.
Eyal's insights are useful for entrepreneurs, product designers, and marketers looking to build products that are not only engaging but also encourage repeat usage. The book discusses ethical considerations in creating habit-forming products and emphasizes the need for a responsible approach to product design.
Overall, "Hooked" provides a framework for understanding user behavior and offers practical strategies for creating products that resonate with users and cultivate lasting habits.
