Habit Formation

Habit formation is the neurological process by which repeated behaviors become automatic. In product terms, it means the user no longer consciously decides to use the product; they use it because a cue in their environment triggers the behavior, and the behavior delivers a reward. Habit formation is the goal of the Hook Model and the mechanism behind daily active user metrics. But not all habits are healthy: habits formed through manipulation (exploiting the Zeigarnik Effect, using fake scarcity) create resentment over time. Ethical habit formation aligns the product's reward with the user's genuine progress.
