Most readers are likely to associate the word “habit” with individual behaviors (like eating healthy food, exercising regularly, and practicing good hygiene). But in The Power of Habit, Charles Duhigg argues that these aren’t the only kinds of habits that affect people’s lives. Instead, he shows that groups, organizations, and even whole societies also depend on the same kind of automatic, unquestioned habits as individuals. This happens because habits are contagious—they can catch on in social groups of any size, whether because of power, peer pressure, or love. In fact, many habits that appear to just impact individuals are actually rooted in social life. Thus, Duhigg’s point about the importance of habits and habit change applies as much to collectives as it does to individuals. He concludes that social groups develop different collective habits from one another because of their different underlying dynamics; these habits then shape how groups evolve and ultimately determine whether or not they achieve their goals.

Duhigg argues that, like individuals, social groups of all sizes depend on habits that make them succeed or fail. This is most evident in small groups of like-minded people, who tend to bond around particular habits and norms. For instance, Alcoholics Anonymous helps people quit drinking in large part because of the group habits it teaches people—AA members learn to habitually come together, tell their stories, and analyze their triggers and mistakes. In addition to replacing drinking, AA also exposes recovering alcoholics to others who have successfully stayed sober for longer. Thus, in AA meetings, small groups build a set of shared habits, which help them recover from their addictions.

Similarly, entire organizations can share and rely on particular habits. Duhigg cites Richard Nelson and Sidney Winter’s influential book An Evolutionary Theory of Economic Change, in which the authors argue that institutions’ routines define their identity, give them consistency, and determine whether they achieve their goals. One example of this is Starbucks’s focus on self-discipline and willpower in employee training. By promoting these key values, Starbucks creates a shared culture for its workforce, helps employees cope with professional and personal setbacks, and ensures better customer service. Duhigg even argues that Starbucks owes its success to this training program, which shows how habits can define and shape institutions as much as they can define and shape people.

Entire societies also have specific habits, which have important consequences for their success. For example, Duhigg argues that the civil rights movement was largely about a shift in habits. Americans started changing the day-to-day habits that sustained segregation, while learning to respond to racist violence with inclusive messages of love, tolerance, and hope. According to Duhigg, Americans first learned these habits from civil rights leaders like Dr. Martin Luther King Jr., but they are now central to American democracy. In fact, King’s principles and habits have even transformed American identity, to the point that many Americans view diversity and tolerance as defining features of their national story. This shows how powerful habits can shape entire societies.

Social groups have distinct, meaningful habits because habits are fundamentally social—they form and change when people come together. Duhigg argues that this can happen in many ways. The first and most direct way is simply through power. Leaders can impose new habits on their followers, like Paul O’Neill did by forcing all of his workers to prioritize safety when he became the CEO of Alcoa. But leaders can also change habits by inspiring their followers. Duhigg cites Dr. King’s influence as a clear example of how moral leadership can spread new kinds of habits throughout a group or society. Next, habits can spread through strong personal and social connections. Namely, groups of people who share close ties—like families, groups of friends, or even AA chapters—often build good habits to help one another out. For instance, the Baptist pastor Rick Warren had his congregants meet in small groups because he knew that this would help them befriend and support one another. He believed that this personal connection would help them sustain a Bible study routine. This shows that small, unified groups can be one of the best places for habits to form and spread. Finally, habits also spread through weak social ties, or peer pressure. To protect their reputations and avoid rejection, people imitate others in a group—including by taking up their habits. For instance, Duhigg argues that the Montgomery bus boycott during the civil rights movement was largely successful because Montgomery’s Black community felt obligated to participate for the sake of the common good. Because networks of casual acquaintances and friends-of-friends tend to be extensive, they can spread new habits far and wide.

For Duhigg, then, there’s little difference between the way habits work for individuals and the way they work for groups, organizations, and entire societies. Just as individuals are defined by their habits but also have the power to change them, groups and institutions always function according to certain ingrained routines but can still transform themselves by changing these routines. And just as individual bad habits (like overeating or compulsive gambling) harm a person’s health, collective bad habits (like unequal power structures or a culture of disrespect) can threaten the strength and sustainability of an entire organization. Not only is it limiting to only talk about individual habits—it’s also wrong, because even individual habits tend to be rooted in a larger social group. Thus, individual and collective habits are always tied together. Often, changing one is the first step toward changing the other.

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.

Dabbing a bit of sunscreen on your face each morning significantly lowers the odds of skin cancer. Yet, while everyone brushes their teeth, fewer than 10 percent of Americans apply sunscreen each day. Why?
Because there’s no craving that has made sunscreen into a daily habit. Some companies are trying to fix that by giving sunscreens a tingling sensation or something that lets people know they’ve applied it to their skin. They’re hoping it will cue an expectation the same way the craving for a tingling mouth reminds us to brush our teeth.

Explanation and Analysis:
In his chapter on cravings, Duhigg explains how the advertising executive Claude C. Hopkins turned toothbrushing into a national habit. Hopkins marketed toothpaste as the routine that would eliminate the dirty film that accumulates on people’s teeth (cue) and leave them with a clean, beautiful smile instead (reward). Even more importantly, Duhigg argues, Hopkins turned toothbrushing into a craving by ensuring that his product, Pepsodent, contained chemicals that gave people a cool, fresh feeling after they brushed their teeth. Duhigg contrasts Hopkins’s success in spreading toothbrushing with marketers’ failure to make other healthy decisions—like applying sunscreen—into consistent habits. As he Dolorem et quae.

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.

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.

O’Neill’s experiences with infant mortality illustrate the second way that keystone habits encourage change: by creating structures that help other habits to flourish. In the case of premature deaths, changing collegiate curriculums for teachers started a chain reaction that eventually trickled down to how girls were educated in rural areas, and whether they were sufficiently nourished when they became pregnant. And O’Neill’s habit of constantly pushing other bureaucrats to continue researching until they found a problem’s root causes overhauled how the government thought about problems like infant mortality.

Explanation and Analysis:
Duhigg argues that keystone habits contribute to further, long-term improvement in three ways. The first is that they create small wins, and the third is that they enable change in an organization’s culture. But here, he explains the second: keystone habits “creat[e] structures that help other habits to flourish.” Paul O’Neill learned this principle while analyzing infant mortality data for the government. He realized that changing college biology curriculums could address infant mortality by improving high school biology instruction and getting better health and nutrition information to under-resourced young mothers. He came to this solution by doing three things. First, Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi. Ut veniam voluptatem.

Chapter 5 Quotes

Starbucks has taught him how to live, how to focus, how to get to work on time, and how to master his emotions. Most crucially, it has taught him willpower.
“Starbucks is the most important thing that has ever happened to me,” he told me. “I owe everything to this company.”

Explanation and Analysis:
After a difficult upbringing, full of chaos and conflict, Travis Leach started working at Starbucks. His heroin-addicted parents taught him poor social and emotional skills, which were inadequate to deal with the day-to-day challenges he faced at work. But whereas his previous jobs all fired him, Starbucks took a different approach: it trained him—like it does all its employees—in order to help him develop the skills he would need to thrive there. Thus, Starbucks essentially substituted for Leach’s family, at least in the way it contributed to Leach’s emotional development. This explains why he calls it “the most important thing Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi. Ut veniam voluptatem.

Chapter 6 Quotes

It may seem like most organizations make rational choices based on deliberate decision making, but that’s not really how companies operate at all. Instead, firms are guided by long-held organizational habits, patterns that often emerge from thousands of employees’ independent decisions. And these habits have more profound impacts than anyone previously understood.

Related Characters: Charles Duhigg (speaker)
Page Number and Citation: 161
Explanation and Analysis:
Duhigg cites the influential economists Richard Nelson and Sidney Winter to argue that organizations depend on habits just as much as people do. At first, this might seem counterintuitive: unlike individual people, organizations tend to follow complex rules about structure, authority, and decision-making. They also usually pursue well-defined goals, like profit or social change, and employ executives whose sole job is to make the organization function efficiently. Therefore, it would be odd if organizations were really driven by arbitrary habits and patterns, which simply become unquestioned dogma over time. Yet this is precisely what Nelson and Winter believe, and Duhigg Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi.

Now, imagine what you would tell a new colleague who asked for advice about how to succeed at your firm. Your recommendations probably wouldn’t contain anything you’d find in the company’s handbook. Instead, the tips you would pass along—who is trustworthy; which secretaries have more clout than their bosses; how to manipulate the bureaucracy to get something done—are the habits you rely on every day to survive. If you could somehow diagram all your work habits—and the informal power structures, relationships, alliances, and conflicts they represent—and then overlay your diagram with diagrams prepared by your colleagues, it would create a map of your firm’s secret hierarchy, a guide to who knows how to make things happen and who never seems to get ahead of the ball.

Page Number and Citation: 164
Explanation and Analysis:
Duhigg further distinguishes between the formal rules that govern organizations, on the one hand, and the actual informal habits that really run them, on the other. Understanding informal hierarchies, norms, and agreements is simply more important to succeeding in a firm than memorizing the rules in the handbook. This is because, while handbooks explain how a company should be run, the informal habits demonstrate how its day-to-day operations actually do run. This distinction explains why Duhigg believes that organizations’ success—like people’s—depends on their habits. Executives’ rules, policies, and expectations can shape these habits, but what really matters is what’s happening Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt.

The same kinds of shifts are possible at any company where institutional habits—through thoughtlessness or neglect—have created toxic truces. A company with dysfunctional habits can’t turn around simply because a leader orders it. Rather, wise executives seek out moments of crisis—or create the perception of crisis—and cultivate the sense that something must change, until everyone is finally ready to overhaul the patterns they live with each day.

Explanation and Analysis:
After explaining how Rhode Island Hospital reformed its poor institutional habits and stopped committing serious medical errors, Duhigg affirms that any struggling institution can follow a similar path—as long as its leaders are wise enough to understand their own limits. Specifically, leaders must understand that they cannot simply order an organization’s culture to change, no matter how much they would like to. Instead, they have to motivate everyone else in the organization to agree to change. To do so, they must get those others to understand the organization’s toxic habits—and those habits’ toxic effects. This is why Duhigg argues that Dolorem et quae. Exercitationem non aut.

Chapter 7 Quotes

As Pole’s computer program crawled through the data, he was able to identify about twenty-five different products that, when analyzed together, allowed him to, in a sense, peer inside a woman’s womb. Most important, he could guess what trimester she was in—and estimate her due date—so Target could send her coupons when she was on the brink of making new purchases. By the time Pole was done, his program could assign almost any regular shopper a “pregnancy prediction” score.

Explanation and Analysis:
Target, the retail giant, hired the mathematical analyst Andrew Pole to try and sell more items to pregnant women and new mothers. Its core assumption was that shopping is essentially based on habits: not only are most of people’s purchases habitual, but people habitually go to the same stores and buy the same goods over time. This meant that, if Target could lure in large numbers of pregnant women, it would likely have return customers for years—specifically, for the years when these women had small children and would buy more household goods than at any other time in their lives.

This insight helped explain why “Hey Ya!” was failing on the radio, despite the fact that Hit Song Science and music executives were sure it would be a hit. The problem wasn’t that “Hey Ya!” was bad. The problem was that “Hey Ya!” wasn’t familiar. Radio listeners didn’t want to make a conscious decision each time they were presented with a new song. Instead, their brains wanted to follow a habit. Much of the time, we don’t actually choose if we like or dislike a song. It would take too much mental effort. Instead, we react to the cues (“This sounds like all the other songs I’ve ever liked”) and rewards (“It’s fun to hum along!”) and without thinking, we either start singing, or reach over and change the station.

Explanation and Analysis:
When Outkast came out with the song “Hey Ya!,” record executives were convinced it would be a massive hit. While their prediction was right—many listeners loved the song, and it did eventually become a hit—they also ran into a classic habit-related problem. Namely, “Hey Ya!” sounded too unfamiliar to radio listeners, so they frequently turned it off. As Duhigg explains here, people don’t usually listen to the radio to hear their favorite songs or discover innovative new music. (This is doubly true in the 21st century, with the rise of streaming.) Instead, the radio is more of a habit—people play Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi. Ut veniam voluptatem.

Whether selling a new song, a new food, or a new crib, the lesson is the same: If you dress a new something in old habits, it’s easier for the public to accept it.

Explanation and Analysis:
To market “Hey Ya!,” record executives asked radio stations to play the song between two common, popular hits. To get Americans to eat organ meat during World War II, the U.S. government proposed they use it in common recipes like meatloaf. And to get targeted ads to their customers without raising suspicion, Target mixed these ads in with generic coupons for random products. All three of these cases depended on the basic principle that Duhigg explains here: the best way to get the public to change its habits is by connecting these new habits to existing ones.

Chapter 8 Quotes

The reason why social habits have such influence is because at the root of many movements—be they large-scale revolutions or simple fluctuations in the churches people attend—is a three-part process that historians and sociologists say shows up again and again:
A movement starts because of the social habits of friendship and the strong ties between close acquaintances.
It grows because of the habits of a community, and the weak ties that hold neighborhoods and clans together.
And it endures because a movement’s leaders give participants new habits that create a fresh sense of identity and a feeling of ownership.
Usually, only when all three parts of this process are fulfilled can a movement become self-propelling and reach a critical mass.

Explanation and Analysis:
Habits, Duhigg argues, aren’t just the key to improving individual lives and building successful organizations. He believes that habits are also the foundation of society itself, which means that effective social change depends on understanding and changing them. Specifically, social movements rely on the three kinds of relationships that Duhigg describes here: strong ties, weak ties, and effective leadership. And, for Duhigg, all three relationships are really about habits—friendship and community are just different long-term patterns of social habits, for instance, while successful leadership is about teaching a large group to faithfully adopt certain habits. Duhigg argues that movements grow Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi. Ut veniam voluptatem.

When faced with the prospect of getting arrested (or worse) in Mississippi, most students probably had second thoughts. However, some were embedded in communities where social habits—the expectations of their friends and the peer pressure of their acquaintances—compelled participation, so regardless of their hesitations, they bought a bus ticket. Others—who also cared about civil rights—belonged to communities where the social habits pointed in a slightly different direction, so they thought to themselves, Maybe I’ll just stay home.

Explanation and Analysis:
In the “Freedom Summer” of 1964, hundreds of students traveled from the northern U.S. to Mississippi to help register Black voters. But hundreds also planned to go, then backed out after a wave of violence at the beginning of the summer. Citing the sociologist Doug McAdam’s research, Duhigg argues that peer pressure was the key factor that determined whether or not students followed through with their plans. Namely, students whose friends also signed up for the Freedom Summer were far more likely to attend it. For Duhigg, peer pressure—like most everything else—is fundamentally a habit. As he explains here, people Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt. Ad dolor at. Quia aperiam eligendi. Ut veniam voluptatem. Aperiam consequuntur mollitia.

This is the third aspect of how social habits drive movements: For an idea to grow beyond a community, it must become self-propelling. And the surest way to achieve that is to give people new habits that help them figure out where to go on their own.

Explanation and Analysis:
Just like habit-changers often relapse into their old habits over time, social movements often lose steam—and sometimes collapse entirely—if they don’t start to see change after some time. For instance, many people started giving up on the Montgomery bus boycott, until Dr. Martin Luther King Jr. gave an impassioned speech that convinced them to continue. Similarly, the small groups at Rick Warren’s church often spent their time discussing gossip—not the Bible—until Warren gave them a unified religious curriculum to follow. King’s speech and Warren’s curriculum demonstrate a crucial principle about how habits help social movements stay afloat. Just like individuals, Dolorem et quae. Exercitationem non aut.
