Introduction
“Hooked: How to Build Habit-Forming Products” by Nir Eyal explores the psychology behind habit formation and provides a framework for building products that captivate users and create long-lasting engagement. Drawing on years of research and experience in the field of behavioral design, Eyal presents a four-step model called the “Hooked Model” that helps product creators understand and leverage the principles of habit formation. In this book summary, we will delve into the key concepts, strategies, and case studies discussed in “Hooked.”

Summary
“Hooked” reveals the underlying principles and strategies used by successful companies to create products that form habits in users. Eyal introduces the Hooked Model, consisting of four stages: trigger, action, variable reward, and investment. He illustrates how these stages work together to create a cycle of user engagement and habit formation.

The trigger is the first step in the Hooked Model, where a user is prompted to take action. Triggers can be external (such as push notifications or email alerts) or internal (such as emotions or thoughts) and play a crucial role in initiating user behavior. Eyal provides insights into how to design triggers that prompt users to take action consistently.

The action phase focuses on making it as easy as possible for users to engage with a product. Eyal emphasizes the importance of reducing friction and simplifying the desired actions to increase user adoption. He discusses techniques such as progressive disclosure and simplification of user interfaces to enhance the user experience.

The variable reward stage is designed to create anticipation and motivation by providing users with unpredictable and satisfying rewards. Eyal explores the psychological principles behind variable rewards and highlights the importance of designing experiences that leave users wanting more. He shares examples and case studies of companies that have successfully implemented variable reward systems in their products.

The final stage, investment, aims to increase user commitment and create a sense of ownership. Eyal explains how encouraging users to invest time, effort, or data into a product can increase their loyalty and make it harder for them to switch to alternatives. He provides strategies for fostering user investment and highlights the role of personalization and customization in creating a sense of ownership.

Eyal also addresses the ethical implications of creating habit-forming products. He emphasizes the importance of responsible design and provides guidance on how to build products that genuinely add value to users’ lives while avoiding harmful addictive behaviors.

Throughout the book, Eyal offers practical advice and actionable steps for product creators. He emphasizes the iterative nature of building habit-forming products and encourages constant testing, learning, and refinement. The book includes case studies from various industries, showcasing how companies like Facebook, Instagram, and Pinterest have successfully applied the principles of the Hooked Model.
