Nir Eyal is a behavioral design and consumer psychology expert. According to Nir, the most successful digital products are habit-forming. What made the iPhone the most profitable product in the world? Why does the average person check their smartphone is 110 times a day? As of the fourth quarter of 2019, Facebook has almost 2. 5 billion monthly active users. What is it about these products? They make use form habits, wedge themselves into our lives, and offer variable rewards.
The Hook Model

Nir Eyal introduces the Hook Model in his book, a four-step process that companies use to build customer habits. It's a cycle that includes a trigger, action, variable reward, and investment. This model is a great tool to understand how to create products that people will use regularly.

Importance of Triggers

Triggers are the first step in the Hook Model. They can be external or internal. External triggers are things like notifications or emails, while internal triggers are emotions or thoughts. Eyal emphasizes that understanding your users' internal triggers is key to creating a product they'll love.

Action and Reward

After the trigger comes the action. This is the behavior done in anticipation of a reward. The reward, however, should not be predictable. According to Eyal, variable rewards are more addictive. So, if you're looking to create a habit-forming product, consider how you can incorporate variable rewards.

Investment for Future Engagement

The last step in the Hook Model is investment. This is where the user puts something into the product, like time or data, which makes them more likely to return. Eyal suggests that the more users invest in your product, the more they value it, leading to higher engagement.

Ethics of Habit-Forming Products

While the Hook Model can be powerful, Eyal also discusses the ethical implications of creating habit-forming products. He encourages creators to ask themselves if they're making the world a better place with their product. So, as you explore the strategies in this book, remember to consider the impact on your users.
