What is the user experiencing just before using your product? What external trigger brings them to your service?
Nir Eyal is careful to include a chapter on ethics. He uses the to help creators determine if they should build a habit-forming product:
This is the "engine" of the Hook Model. Habit-forming products don't just give a reward; they give a one. Derived from B.F. Skinner’s experiments with operant conditioning, variability creates a "craving" in the brain. The Tribe: Social validation (likes, comments).
Nir Eyal’s Hooked is more than just a business book; it is a psychological deep dive into how our brains interact with technology. Whether you are a developer, a marketer, or just a curious user, understanding the Hook Model reveals the invisible strings that pull us toward our screens every day.
The action is the simplest behaviour done in anticipation of a reward. Following , an action occurs when three things align: Motivation, Ability, and a Trigger. If a task is too hard (low ability), the user won't do it. This is why "one-click" buttons and "infinite scrolls" are so effective—they make the action effortless. 3. Variable Reward
It doesn't improve lives, and the creator doesn't use it (exploitation). How to Apply "Hooked" to Your Product
The creator uses it, but it doesn't necessarily improve lives (e.g., certain games). The Entertainer: It's fun, but the creator doesn't use it.
This is where the magic happens. Over time, the product becomes associated with a thought, an emotion, or a routine. For instance, when you feel lonely, you might instinctively open Instagram. The goal is for the product to solve a recurring internal itch.
