Routine Term Analysis

In the habit loop, a routine is the habit itself—or the automatic series of actions that someone takes in response to the cue. The routine then leads to a reward. For instance, smokers learn to perform a specific routine—smoking—in response to stress.

Chapter 1 Quotes

Habits, scientists say, emerge because the brain is constantly looking for ways to save effort. Left to its own devices, the brain will try to make almost any routine into a habit, because habits allow our minds to ramp down more often. This effort-saving instinct is a huge advantage. An efficient brain requires less room, which makes for a smaller head, which makes childbirth easier and therefore causes fewer infant and mother deaths. An efficient brain also allows us to stop thinking constantly about basic behaviors, such as walking and choosing what to eat, so we can devote mental energy to inventing spears, irrigation systems, and, eventually, airplanes and video games.

Explanation and Analysis:
After explaining the important behavioral and neurological difference between conscious decisions and unconscious habits, Duhigg investigates why this this difference exists in the first place. According to the available scientific evidence, Duhigg writes, habits give organisms a significant evolutionary advantage because they conserve energy. Put simply, habits automate certain decisions and behaviors by moving them from the conscious part of the brain to the unconscious one. This frees up mental energy for the kinds of tasks for which humans are uniquely adept—like learning, problem-solving, and creative pursuits. In a way, habits are nature’s original kind of technology. Just like people Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi.

Over time, this loop—cue, routine, reward; cue, routine, reward—becomes more and more automatic. The cue and reward become intertwined until a powerful sense of anticipation and craving emerges. Eventually, whether in a chilly MIT laboratory or your driveway, a habit is born.

Explanation and Analysis:
The brain learns new habits by combining three things—a cue, routine, and reward—into an automatic mental loop. The cue is the signal that tells the brain it’s time to start the routine (or the habitual behavior). Then, after the routine, the brain receives a reward, which signals that the loop is over. Rewards can be sensory (like the feeling of stimulation associated with drinking coffee) or psychological (like the feeling of accomplishment athletes may feel after winning a game). Over time, the brain learns to automatize this entire process: when it notices the cue, it automatically begins the routine, and Dolorem et quae. Exercitationem non aut. Eveniet dolor non.

Chapter 2 Quotes

Each change was designed to appeal to a specific, daily cue: Cleaning a room. Making a bed. Vacuuming a rug. In each one, Febreze was positioned as the reward: the nice smell that occurs at the end of a cleaning routine. Most important, each ad was calibrated to elicit a craving: that things will smell as nice as they look when the cleaning ritual is done. The irony is that a product manufactured to destroy odors was transformed into the opposite. Instead of eliminating scents on dirty fabrics, it became an air freshener used as the finishing touch, once things are already clean.

Explanation and Analysis:
When Proctor & Gamble scientists developed an innovative new odor-eliminating spray called Febreze, they thought they would capture a whole new market: people who want to eliminate foul smells from their homes and possessions. Drake Stimson and the company’s other marketing executives just had to figure out how to appeal to these people. Specifically, to sell lots of Febreze, they had to make people start using it as a habit. But they quickly ran into a problem: it was almost impossible to turn eliminating odors into a habit. People who lived in smelly houses often either didn’t know or didn’t Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi.

Chapter 3 Quotes

His coaching strategy embodied an axiom, a Golden Rule of habit change that study after study has shown is among the most powerful tools for creating change. Dungy recognized that you can never truly extinguish bad habits.
Rather, to change a habit, you must keep the old cue, and deliver the old reward, but insert a new routine.
That’s the rule: If you use the same cue, and provide the same reward, you can shift the routine and change the habit. Almost any behavior can be transformed if the cue and reward stay the same.

Explanation and Analysis:
The legendary football coach Tony Dungy turned around two unsuccessful teams—the Tampa Bay Buccaneers and the Indianapolis Colts—by teaching his players to develop new habits. His approach was unprecedented and controversial in the high-stakes world of the NFL, but it was also remarkably successful. Duhigg argues that Dungy succeeded by applying the key principle he calls the Golden Rule of habit change: “keep the old cue, and deliver the old reward, but insert a new routine.” For instance, Dungy didn’t change the way his players looked at the opposing team’s formation before a play (the cue). Instead, he changed the Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi. Ut veniam voluptatem. Aperiam consequuntur mollitia.

Notice how closely this study hews to the Golden Rule of habit change: Even when alcoholics’ brains were changed through surgery, it wasn’t enough. The old cues and cravings for rewards were still there, waiting to pounce. The alcoholics only permanently changed once they learned new routines that drew on the old triggers and provided a familiar relief.

Explanation and Analysis:
While cravings are often the decisive factor that makes habits stick, researchers have found that eliminating them often isn’t enough to eliminate bad habits. This is because powerful habit loops—like drinking, for alcoholics—often come to serve other purposes besides merely satisfying cravings. In the study Duhigg describes here, neuroscientists used brain implants to stop alcoholics from craving alcohol. But the alcoholics kept drinking because they didn’t have any other way to cope with stress. In other words, they didn’t crave alcohol’s chemical effects as much as the routine of drinking, which gave them a sense of relief. Even though a Dolorem et quae. Exercitationem non aut.

Often, we don’t really understand the cravings driving our behaviors until we look for them.

Explanation and Analysis:
In order to change their habits, Duhigg argues, people first need to understand those habits. In other words, they have to identify the cues, rewards, and routines that make up their habit loops. This process can be far more difficult and complex than it sounds, because people frequently misunderstand the real motives behind their habits. For instance, Duhigg notes that many smokers assume that they crave nicotine, when in reality they might crave the regular breaks or opportunities to socialize that smoking gives them. If they keep trying to replace nicotine cravings when they really crave breaks, they are bound Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi. Ut veniam voluptatem. Aperiam consequuntur mollitia. Provident expedita delectus. Occaecati ea suscipit. Optio ut iste. Voluptas aut occaecati.

How do habits change?
There is, unfortunately, no specific set of steps guaranteed to work for every person. We know that a habit cannot be eradicated—it must, instead, be replaced. And we know that habits are most malleable when the Golden Rule of habit change is applied: If we keep the same cue and the same reward, a new routine can be inserted.
But that’s not enough. For a habit to stay changed, people must believe change is possible. And most often, that belief only emerges with the help of a group.

Explanation and Analysis:
At the end of his third chapter, Duhigg summarizes the three key ingredients that tend to make habit change successful. The first is to change habits through the Golden Rule—which means replacing undesirable routines with more desirable ones, while keeping cues and rewards the same. The second is believing in one’s capacity to change, which motivates people to keep trying when they encounter obstacles. And the third is to find a social support group, preferably of people who understand the bad habit one is trying to kick. Social support serves several important functions: groups make people accountable for maintaining new Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at.

Chapter 4 Quotes

What most people didn’t realize, however, was that O’Neill’s plan for getting to zero injuries entailed the most radical realignment in Alcoa’s history. The key to protecting Alcoa employees, O’Neill believed, was understanding why injuries happened in the first place. And to understand why injuries happened, you had to study how the manufacturing process was going wrong. To understand how things were going wrong, you had to bring in people who could educate workers about quality control and the most efficient work processes, so that it would be easier to do everything right, since correct work is also safer work.
In other words, to protect workers, Alcoa needed to become the best, most streamlined aluminum company on earth.

Page Number and Citation: 106
Explanation and Analysis:
In this passage, Duhigg explains precisely how Alcoa CEO Paul O’Neill’s focus on worker safety led to a series of other valuable habit changes throughout the company. In essence, O’Neill realized that the changes Alcoa needed to make to protect its workers were the same changes that it needed to make to become more profitable and efficient. First, as Duhigg explains here, O’Neill recognized that safety was a keystone issue because it reflected how the company’s core manufacturing processes were running. Thus, he viewed every worker injury not only as a tragedy to prevent in the future, but also as Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at.

Chapter 5 Quotes

What employees really needed were clear instructions about how to deal with inflection points—something similar to the Scottish patients’ booklets: a routine for employees to follow when their willpower muscles went limp. So the company developed new training materials that spelled out routines for employees to use when they hit rough patches. The manuals taught workers how to respond to specific cues, such as a screaming customer or a long line at a cash register. Managers drilled employees, role-playing with them until the responses became automatic. The company identified specific rewards—a grateful customer, praise from a manager—that employees could look to as evidence of a job well done.
Starbucks taught their employees how to handle moments of adversity by giving them willpower habit loops.

Related Characters: Charles Duhigg (speaker)
Page Number and Citation: 145
Explanation and Analysis:
Duhigg analyzes Starbucks’s training practices in order to explain exactly how willpower contributes to habit change. People with high willpower, just like people who believe in their own capacity for change, are more likely to overcome stressful situations (or “inflection points”). And people who can overcome this kind of stress are also more likely to achieve their goals. Of course, these goals can include long-term habit change: willpower helps people stick with new habits by giving them the strength they need to resist relapsing into old ones. Starbucks trains employees to deal with stressful “inflection points” by rehearsing routines with Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at.

Chapter 9 Quotes

Every habit, no matter its complexity, is malleable. The most addicted alcoholics can become sober. The most dysfunctional companies can transform themselves. A high school dropout can become a successful manager.
However, to modify a habit, you must decide to change it. You must consciously accept the hard work of identifying the cues and rewards that drive the habits’ routines, and find alternatives. You must know you have control and be self-conscious enough to use it—and every chapter in this book is devoted to illustrating a different aspect of why that control is real.

Explanation and Analysis:
In the closing section of his book, Duhigg reaffirms his steadfast belief in the possibility and power of habit change. This isn’t just a personal preference—rather, it’s based on Duhigg’s years-long survey of the available scientific evidence. The research has convinced him that habit change is always possible: even people facing the most severe addictions and most adverse circumstances can change. Habit change is also relatively straightforward—although it’s by no means easy. People must “decide to change,” then determine how their cue-routine-reward habit loop works. Then, they have to replace the routine with an alternative one. It helps if they Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi.
