One-line summary:

Hooked is a guide to building habit-forming products that explores the psychology behind why certain products become so addictive and provides a framework for creating products that keep users coming back for more.

The Power of Habits

In the first section of the book, author Nir Eyal introduces the concept of the “Hook Model,” a four-step process that companies can use to create habit-forming products. He explains that habits are formed through a cycle of triggers, actions, rewards, and investments. Triggers prompt users to take action, which leads to a reward, and ultimately, an investment in the product. By understanding this cycle, companies can design products that become ingrained in users’ daily routines.

Triggers: External and Internal

Eyal delves into the different types of triggers that can prompt user action. External triggers are cues in the user’s environment, such as notifications or advertisements, that prompt them to engage with a product. Internal triggers, on the other hand, are emotions or thoughts that drive users to seek out a product as a solution. By understanding the internal triggers that lead users to their product, companies can create more effective external triggers to drive engagement.

Variable Rewards: The Pursuit of Dopamine

The next step in the Hook Model is the reward phase, where users receive gratification for their actions. Eyal explains that variable rewards are particularly effective in creating habits because they tap into the brain’s dopamine system, which is responsible for feelings of pleasure and motivation. By providing users with unpredictable rewards, such as social validation or new content, companies can keep users hooked and coming back for more.

Investments: Increasing User Commitment

The final step in the Hook Model is the investment phase, where users put something of value into the product. This can be in the form of time, data, money, or social capital. Eyal emphasizes the importance of making these investments public, as it increases the user’s commitment to the product and creates a sense of ownership. By encouraging users to invest in the product, companies can further solidify the habit loop and increase user retention.

Key Takeaways:

• Understanding the psychology behind habit formation is crucial for creating successful products.
• Triggers, both external and internal, play a key role in prompting user action.
• Variable rewards tap into the brain’s dopamine system and keep users engaged.
• Investments increase user commitment and create a sense of ownership.
