Condition: BRAND NEW Format: Hardback ISBN: 9780241184837 Publisher: Portfolio Penguin Overview: Why do some products become part of our daily routine while others are forgotten within days? In Hooked, Nir Eyal reveals the psychology behind the world's most engaging apps and services. Introducing his groundbreaking Hook Model - Trigger, Action, Variable Reward, Investment - Eyal shows how companies like Twitter, Instagram, Pinterest and the Bible App quietly build lasting user habits. Packed with behavioural science, real-world case studies and practical frameworks, this hardback is essential reading for anyone who designs, markets or simply wants to understand the products that hook us. About the Book: Hooked is Nir Eyal's practical playbook for creating habit-forming products, distilled from years of research and consulting in Silicon Valley. At its heart is the four-step Hook Model: triggers that cue a user to act, the simple actions they take, the variable rewards that keep them curious, and the small investments that make future engagement more likely. Rather than abstract theory, this is the how-to guide Eyal wishes had existed when he was a start-up founder. He weaves rigorous behavioural science with vivid examples - from the iPhone's notification badges to Twitter's endless scroll - showing exactly how habit-forming technology is engineered. The tone is calm, methodical and refreshingly free of jargon, making complex psychology accessible to product managers, designers, marketers, founders and curious general readers alike. Each chapter offers actionable frameworks and questions you can apply directly to your own product or business, without needing a team of data scientists. Crucially, the book also addresses the ethics of habit-forming design, helping readers build products that respect users' time and wellbeing. Whether you're refining an existing app, launching a new platform, or simply trying to understand why you can't put your phone down, Hooked offers a clear, well-argued path through one of the most important conversations in modern business and technology.
