Nir Eyal’s Hook Model
The Hook Model is a concept developed by Nir Eyal, a writer and entrepreneur. It is a framework designed to help create habit-forming products and services by engaging users on a deeper level. Eyal’s model is based on four key components, which are meant to encourage user interactions and repeat usage, ultimately leading to user addiction. These components are:
Trigger: Triggers are cues that prompt users to take action, either through external stimuli or internal motivations. External triggers can be notifications, advertisements, or even recommendations from friends, while internal triggers stem from users’ thoughts or emotions, such as boredom or a need for social connection.
Action: The action is the simple task the user performs in response to the trigger. The action will depend on the context and product, but generally, it should be easy to do and have a clear connection to the trigger. An example might be swiping left or right on a dating app after receiving a notification.
Variable Reward: Rewarding users for taking action is an essential part of the Hook Model. Variable rewards refer to the idea that users receive varying levels of gratification for their actions - this unpredictability keeps them engaged and curious. Social media platforms are excellent examples, as users receive likes, comments, or retweets randomly, prompting them to keep interacting to trigger more rewards.
Investment: This component focuses on users investing time or effort into the product, which increases the likelihood of future engagement. An investment might include creating a profile, adding friends, or curating content. Users often feel a sense of ownership after investing in a product, making them more likely to return and continue using it.
By incorporating these components into your UX design, you can create experiences that encourage users to develop habits and become more attached to your product. Keep in mind, however, that “addiction” is not the primary goal - rather, it’s about promoting genuine value and enhancing users’ lives in a positive manner.
