Hooked: How to Build Habit-Forming Products by Nir Eyal is a book that explores the psychology behind why we form habits and how products can be designed to encourage those habits. Eyal argues that there are four key steps involved in creating a habit-forming product: trigger, action, variable reward, and investment.
The trigger is what gets the user to start using the product. It could be a notification, a reminder, or even just the sight of the product's icon on their phone. The action is what the user does when they interact with the product. It could be anything from scrolling through a feed to playing a game. The variable reward is what keeps the user coming back for more. It could be a new piece of content, a notification that they've been upvoted, or even just the feeling of accomplishment that comes from completing a task. The investment is what the user does to make the product more useful or enjoyable. It could be adding friends, following accounts, or even just learning how to use the product more effectively.
Eyal provides a number of examples of how these four steps have been used to create habit-forming products, including Facebook, Twitter, and the iPhone. He also provides a number of tips for product designers on how to use these principles to create their own habit-forming products.
Hooked is an engaging and informative book that provides valuable insights into the psychology of habit formation. It is a must-read for anyone who wants to create products that people can't put down.
