The Role of Triggers in Habit Formation

Triggers are essential in initiating and maintaining user habits. Eyal categorizes triggers into external and internal types. External triggers, like notifications or advertisements, prompt users to take action. For example, a Coca-Cola vending machine uses visual cues to encourage purchase. Internal triggers, on the other hand, are emotions or thoughts that prompt action without external stimuli. Eyal emphasizes, 'The ultimate goal of all external triggers is to propel users into and through the Hook Model so that, after repeated use, the trigger becomes internalized.'
