"Hooked" discusses the psychology behind why some products and services become habit-forming, and how companies can design products that create lasting user engagement. The book argues that the key to creating habit-forming products is to understand and tap into the underlying psychological triggers that drive user behaviour.
The book presents a framework called the "Hook Model," which consists of four stages: trigger, action, variable reward, and investment. The authors argue that by designing products that successfully navigate these four stages, companies can create products that engage users and keep them coming back.
Overall, this book is a valuable resource for anyone interested in understanding the psychology behind habit-forming products and learning how to design products that create lasting user engagement.
