Cue-Routine-Reward

Cue-routine-reward is the three-part framework that describes the structure of every habit, as outlined by Charles Duhigg in The Power of Habit. Every habitual behavior — good or bad — follows this same pattern.

The Three Components

Cue

The cue is the trigger that tells your brain to initiate a behavior. Cues generally fall into five categories: time of day, location, emotional state, other people, and the action immediately preceding it.

For example, feeling stressed after a meeting (emotional state) might trigger reaching for a snack.

Routine

The routine is the behavior itself — the thing you actually do. This is the most visible part of the habit and the component most people try to change directly. But without addressing the cue and reward, willpower alone rarely holds.

Routines can be physical (grabbing a snack), mental (worrying about a deadline), or emotional (venting frustration).

Reward

The reward is the payoff that tells your brain this loop is worth remembering. Rewards can be obvious — sugar, caffeine, social validation — or subtle, like the relief of distraction or a brief sense of accomplishment.

Over time, your brain begins to crave the reward the moment it detects the cue. This craving is what drives the loop and makes habits self-reinforcing.

A Simple Example

Say you have a habit of checking your phone first thing in the morning:

• Cue: Your alarm goes off and you pick up your phone to silence it.
• Routine: You start scrolling through notifications and social media.
• Reward: A hit of novelty and social connection that wakes your brain up.

To change this habit, you keep the cue (alarm goes off) and the reward (mental stimulation), but swap the routine — maybe you open a meditation app instead.

Identifying the Cue Is the Key

Duhigg argues that the most important step in changing any habit is diagnosing the cue. Most people focus on the routine (the unwanted behavior) without understanding what triggers it. Once you isolate the cue, you can experiment with different routines that deliver a similar reward.

This is where habit stacking becomes useful. Instead of fighting an existing cue, you can use a reliable behavior you already perform as the cue for a new, positive routine.
