Most products solve a problem once. Habit-forming products solve a problem continuously. Eyal argues that habits are "behaviors done with little or no conscious thought." The internet is crowded with “vitamins” (nice-to-have products) but starved for “painkillers” (must-have solutions). Hooked teaches you how to turn your vitamin into a painkiller by building a relationship loop.

Hooked presents a framework for designing products that form user habits by repeatedly hooking them through a four-phase loop: Trigger, Action, Variable Reward, and Investment. Eyal argues habit-forming products provide long-term engagement without relying solely on costly advertising or constant promotions. The book blends behavioral psychology, product design, and business strategy to show how small design choices can create large behavioral change.

This is the most cited section of the hooked pdf. Why do we get bored of slot machines but never bored of Twitter? Because of predictable vs. variable rewards. If you reward a dog with a treat every time it sits, it will sit when hungry. If you reward it sometimes, it will sit obsessively (variable reinforcement schedule). Eyal outlines three types of variable rewards:

The Golden Rule: Give the user what they came for, but leave them wanting more. The "variable" part breaks the pattern, keeping the brain locked in. 2️⃣ Action: The simplest behavior done in anticipation

The trigger is useless without action. Eyal borrows from Dr. BJ Fogg’s Behavior Model: B = MAT (Behavior = Motivation + Ability + Trigger). To get the user to act, you must make it remarkably easy.

A habit starts with a trigger. You cannot build a habit if the user never starts the engine.
