The Influence Revolution: How Behavior Change Masters Transform the Impossible
Ever wondered why some people can transform hardened criminals into productive citizens, while others can't even get their teenagers to clean their rooms? "Influencer" by Joseph Grenny and his co-authors reveals the secret: behavior change isn't magic-it's science. This groundbreaking book, beloved by CEOs like Tony Hsieh of Zappos and featured in Harvard Business Review's must-read list, has transformed how organizations approach change management. Since its 2007 publication, it has become required reading at companies like Microsoft and Salesforce, where executives credit its principles with driving successful cultural transformations. What makes this book particularly powerful is its universal application-whether you're trying to lose weight, improve workplace culture, or solve global health crises, the same principles apply. As Oprah Winfrey, who featured the authors on her show, noted: "Understanding influence is the most important skill we can develop for creating meaningful change in our lives and the world around us."

The Science of Profound Influence
Most of us face seemingly insurmountable challenges-from workplace quality programs that yield no improvements to personal weight battles to dangerous neighborhood situations. We've been conditioned to attempt change briefly before surrendering, seeking serenity by accepting what we cannot change. But this is a trap. The profound, pervasive problems we face don't require solutions that defy natural laws-they require people acting differently.
The common thread running through our triumphs and tragedies is our ability (or inability) to exert influence. If we recognized this, we'd invest enormous energy in expanding our influence repertoire, trying new approaches when our usual tactics fail. Instead, we grumble, threaten, ridicule, and ultimately cope rather than change situations.
People excel at inventing ways to cope rather than solving problems. At work, we abandon quality programs and install inspectors. With failing schools, we complain to friends and tutor our own children. For weight issues, we own multiple wardrobe sizes. Even with global crises like AIDS, over 90% of international conference discussions focus on coping with effects rather than changing behaviors that cause the disease.
Despite widespread resignation, remarkable influencers exist who know exactly how to change human behavior. Dr. Mimi Silbert of the Delancey Street Foundation transforms former felons, addicts, and gang members-people with typically four felony convictions and years of homelessness-into productive citizens. Within hours of joining, these individuals begin working in Delancey's restaurants and businesses. Remarkably, over 90% never return to drugs or crime, instead earning degrees and becoming professionals. And Silbert accomplishes this without therapists, professional staff, donations, grants, or guards-just a powerful influence strategy that has transformed 14,000 lives over 30 years.
Behind every great influencer stands brilliant research. Albert Bandura, the most cited living psychologist, transformed behavior change by demonstrating how powerfully humans learn through observation. His classic Bobo doll experiment showed that children who watched an adult model novel aggressive behaviors immediately replicated and even creatively expanded upon them. This work challenged behaviorism's simplistic reward-punishment model, revealing that humans observe, think, and then act-meaning effective influence requires changing how people think before changing how they behave.
The good news: our ineffectiveness at influencing stems from inability, not character flaws. We can become powerful influencers by expanding our self-image and studying proven strategies. There's no single silver bullet-profound problems require multiple influence methods working together.

Finding the Vital Few: The Key to Massive Change
Before developing influence strategies, you must identify specific behaviors to change. The breakthrough discovery of influence masters is that enormous change often comes from focusing on just a few vital behaviors.
In 1988, Thailand faced an AIDS crisis when King Rama IX's birthday amnesty released 30,000 prisoners, unleashing HIV into the general population. Within five years, an estimated one million Thais were infected, with experts predicting eventual infection of 25% of adults. Dr. Wiwat Rojanapithayakorn initially failed with traditional awareness campaigns, but when he analyzed the data, he discovered 97% of new infections came through sex workers. By focusing on one vital behavior-ensuring sex workers demanded condom use-he cut new infections by 80% within two years, preventing an estimated 5 million infections by 2004.
Influence masters insist on identifying specific behaviors before developing strategies. Many people fail by confusing outcomes with behaviors-like Henry Denton's weight loss strategy to "eat fewer calories than I burn," which describes a result rather than specific actions. Without specific behaviors, people remain uncertain about proper actions.
The most important discovery in influencing change is focusing on a handful of high-leverage behaviors. When you discover a few vital behaviors and change those, even massive problems can collapse like a house of cards. Relationship scholar Howard Markman demonstrated this by showing how watching couples argue for just 15 minutes reveals vital behaviors that predict with 90% accuracy whether they'll be happily together five years later. The key isn't examining their backgrounds or shared interests, but observing specific behaviors during disagreements-like avoiding blame and escalation while showing respect and taking timeouts when needed.
When controlled experiments aren't practical, "positive deviance" offers a powerful method for discovering vital behaviors. This approach involves finding situations where a problem should exist but doesn't, then identifying what those successful outliers do differently. The Carter Center team used this method to combat Guinea worm disease in Africa, discovering that women in healthy villages filtered water through their skirts when transferring it between pots, effectively removing disease-causing larvae. This locally invented solution became a vital behavior that could be taught throughout affected regions without requiring expensive Western interventions.
Beyond identifying behaviors that prevent problems, we must also discover recovery behaviors for when mistakes occur. In the Guinea worm example, villagers developed two critical recovery behaviors: speaking up when neighbors showed infection symptoms (overcoming shame), and keeping infected individuals away from the water supply during the worm's emergence. When everyone practiced these behaviors for a full year, the parasite cycle was broken.
The search for vital behaviors requires four key steps: focus on specific behaviors rather than vague outcomes; look for the few high-leverage behaviors that create cascading change; identify recovery behaviors that help people get back on track after inevitable mistakes; and test your conclusions by implementing the behaviors and measuring both their adoption and the resulting outcomes.

Transforming Minds: The Foundation of Behavior Change
Before people will change their behavior, they must first change their minds-but this isn't easy when dealing with resistant problems. Dr. Albert Bandura, having previously demonstrated that humans learn by observing others, turned his attention to changing deeply held but inaccurate beliefs. He chose to study snake phobics as perfect subjects: their beliefs are demonstrably inaccurate, and they strongly resist change despite constant pressure from others.
Bandura's snake phobia experiment aimed to help subjects eventually sit with a six-foot boa constrictor. Rather than lecturing, which rarely works with phobics, Bandura employed vicarious experience-having subjects watch therapists handle snakes safely. Gradually, subjects progressed from entering the room to touching the snake with protective gear to finally holding the snake unprotected. Remarkably, this three-hour process completely "cured" lifelong phobics, with results lasting a lifetime and boosting their confidence to overcome other challenges.
Bandura's work reveals fundamental principles of behavioral change: People choose behaviors based on what they think will happen as a result-their mental maps of cause and effect. To change behavior, you must change these maps. Only two questions matter: "Is it worth it?" and "Can I do it?" While verbal persuasion is our default influence tool, it rarely works with resistant problems, often feeling like nagging or manipulation. Personal experience is the ultimate persuader, as demonstrated when American manufacturing employees only believed Japanese competitors' superior productivity after witnessing it firsthand rather than hearing speeches from bosses they distrusted.
When direct experience isn't possible, vicarious experiences become powerful change tools. Miguel Sabido's soap opera "Ven Conmigo" demonstrated this power when a storyline about adult literacy drove 250,000 people to seek literacy materials. Similarly, the Tanzanian radio drama "Twende na Wakati" effectively changed beliefs about HIV/AIDS through a controversial character named Mkwaju who contracted AIDS through risky behaviors. The character became so real that villagers threw stones at the actor when they recognized his voice in public.
Stories create powerful vicarious experiences that help people view the world differently. Unlike verbal persuasion, which suffers from translation problems and stripped-down abstractions, well-told narratives provide concrete, vivid details that make cause-and-effect relationships memorable. When we try to convince through direct persuasion, listeners hear our words through their own filters, often missing our intended meaning. Stories overcome this limitation by providing rich context that transports listeners into the experience itself.
People resist verbal persuasion the moment they sense you're trying to convince them, either because they doubt your expertise or question your motives. Stories bypass this resistance by helping listeners visualize real-world scenarios. Research shows that even MBA students found stories more credible and memorable than facts or charts. Stories transport people away from critical thinking into participation, preventing counterarguments from forming in the first place.
Stories trigger genuine emotions that facts alone cannot. When people are transported into a narrative, they don't merely sympathize with characters-they empathize, generating emotions as if they were experiencing the events themselves. This happens because of "mirror neurons" that fire when we observe actions, allowing us to "feel, not think" our way into understanding others.
To create behavior change, we must help people alter their mental maps of cause and effect, particularly around two key questions: "Will it be worth it?" and "Can I do it?" Rather than relying on verbal persuasion, we should use methods that are more understandable, believable, and compelling-like poignant stories that show both the negative consequences of current behaviors and the positive outcomes of new ones.

The Six Sources of Influence: Making Change Inevitable
To create change after discovering vital behaviors and helping people see the need for change, simplistic approaches rarely work with complex problems. It's like hiking the Himalayas with only a fanny pack-there's nothing wrong with Gatorade and a granola bar, but you'll need much more. Bringing a simple solution to a resistant problem almost never succeeds.
All forces that impact human behavior work on just two mental maps. People ask: "Can I do what's required?" (ability) and "Will it be worth it?" (motivation). These two domains can be further divided into personal, social, and structural sources, creating six distinct sources of influence. Influence masters draw from all six sources rather than relying on simplistic single-source strategies like training programs or harsh penalties. To succeed with complex problems, you must overdetermine success by combining multiple influence strategies.
Using the Guinea worm eradication project as an example, all six sources of influence must be addressed: personal motivation (victims want relief by soaking in water), personal ability (villagers need proper filtering skills), social motivation (outsiders aren't trusted), social ability (community assistance is essential), structural motivation (infected people need to work to survive), and structural ability (proper tools and village layout). Leave out even one source, and your influence strategy will likely fail.
Capitolo 6
Making the Undesirable Desirable: Personal Motivation
The first source of influence focuses on making vital behaviors intrinsically satisfying rather than relying on external pressure. When people find behaviors inherently rewarding, external motivation becomes unnecessary. The key question is whether we can transform how people experience behaviors from loathsome to gratifying.
Terri, a former convict at Delancey Street with a manslaughter conviction, exemplifies this transformation when she finds herself crying because she genuinely cares about delivering financial data - a profound shift in her intrinsic motivation. As psychiatrist M. Scott Peck notes, humans can "transcend and transform our own nature," finding satisfaction in previously unpleasant behaviors.
People often resist new behaviors because they incorrectly predict how these activities will make them feel. At Delancey Street, Dr. Silbert addresses this by requiring residents to try new behaviors rather than attempting verbal persuasion. Her approach is simple: "You can't hate Chinese food until you've tried it." Most residents eventually discover unexpected satisfaction in these activities.
Activities can be transformed through gamification when immediate enjoyment isn't present. Mihalyi Csikszentmihalyi's research shows that adding reasonably challenging goals and clear feedback can make almost any activity engaging. When activities can't be gamified, deeper motivation must come from within - when people invest themselves in an activity, making success a measure of identity rather than just achievement.
During stress, people often disconnect from their deeper values. Dr. Stanton Peele's research reveals that connecting behavior to broader moral values best predicts success in overcoming addictive habits. At Delancey, Mimi Silbert applies this by reframing "ratting out" as helping others succeed: "If you turn others in, it helps them. We do it because we must help each other."
Traditional approaches to helping others reconnect with values can backfire if they seem controlling. William Miller's research shows that confrontational approaches often fail, while "motivational interviewing" - helping patients discover necessary changes themselves through open questions - proves more effective. The key is helping people determine their own values rather than imposing an agenda.
Capitolo 7
Building Essential Skills: Personal Ability
Personal ability is often overlooked as a critical factor in behavior change. Leaders frequently make the "fundamental attribution error"-assuming people don't change simply because they lack motivation, when ability may be the real issue. Corporate training often consists of passive learning without practice, creating resentment rather than change. Influence masters instead overinvest in strategies that increase ability rather than just motivation.
Henry, struggling with his diet, succumbs to chocolate temptation and believes he lacks the willpower and genetic makeup to resist. He's trapped in what Carol Dweck calls a "fixed mindset"-believing his abilities are unchangeable. However, research shows that traits once considered genetic gifts or personality traits can actually be learned. Henry can adopt a "growth mindset" and develop the learning skills that influence masters use. Characteristics like self-discipline aren't fixed traits but learnable skills.
Walter Mischel's marshmallow experiments revealed that children who could delay gratification became adults who were more socially competent, self-assertive, and dependable, scoring 210 points higher on SATs than those who couldn't wait. Companion studies confirmed that self-control predicts better outcomes across all life domains. But is this ability hardwired? Mischel and Bandura discovered that when children who couldn't delay gratification observed adults using delay techniques, they quickly learned and retained these skills. The conclusion: delayers aren't simply born with more willpower-they've mastered specific, learnable techniques that help them resist temptation and focus on long-term goals.
Psychologist Anders Ericsson has demonstrated that elite performance comes not from genetic gifts but from deliberate practice. His research shows that Olympic-level figure skaters practice skills they haven't yet mastered, while amateurs practice what they already know or socialize instead. This pattern holds true across all domains-from chess to violin to interpersonal skills. Most professionals plateau at an "acceptable" level, with improvement unrelated to years of experience. The difference between mediocrity and mastery isn't time invested but how that time is used.
Deliberate practice requires complete concentration-no daydreaming or autopilot. Elite performers maintain this intense focus for only about an hour at a time, typically in the morning when fresh. Even the most dedicated practitioners rarely exceed five hours of deliberate practice daily, often supplementing with naps and extra sleep to maintain mental sharpness.
The quality of practice matters more than quantity. Serious chess players improve rapidly by comparing their moves to masters' moves, immediately identifying gaps in their thinking. Olympic swimmer Natalie Coughlin focuses on minute details of each stroke, counting strokes per lap and making instant adjustments. This approach contradicts traditional teaching methods that minimize testing-research shows frequent feedback accelerates learning by normalizing assessment and providing constant comparison against standards.
Breaking complex skills into achievable mini-goals drives motivation and success. Top performers set specific, process-oriented goals (like "keep the elbow in" for basketball free throws) rather than vague outcome goals (like "improve concentration"). This specificity helps them identify exactly what went wrong when they fail. When teaching fearful learners, providing short-term, specific, easy, low-stakes goals builds confidence through immediate success.
Our brains operate in two distinct modalities: the "hot" or "go" system (controlled by the amygdala) that triggers quick, emotional responses for survival, and the "cool" or "know" system (frontal lobe) for higher-level cognitive processing. Problems arise when we employ the wrong system for a situation, particularly when our "go" system activates inappropriately for non-threatening situations like workplace conflicts or food cravings.
Mischel's marshmallow studies revealed that "delayers" managed their emotions through distraction techniques-covering their eyes, turning away, singing, or inventing games. When researchers taught these tactics to other children, their ability to delay gratification improved significantly. The key wasn't willpower or focusing on the reward (which actually decreased persistence), but redirecting attention elsewhere.
Capitolo 8
The Power of Social Influence: Harnessing Peer Pressure
No resource is more powerful for influencing profound and persistent problems than the persuasion of our social networks. Smart influencers recognize and harness the immense power humans hold over one another rather than denying or lamenting it.
Stanley Milgram's infamous 1961 experiments revealed a disturbing truth about human nature. When ordinary Connecticut citizens were instructed by an authority figure to administer increasingly painful electric shocks to a "learner" (actually an actor receiving no shocks), a shocking 65% continued all the way to the maximum 450-volt level despite hearing screams, protests about heart conditions, and eventually silence from their victims. These weren't zealots or sociopaths-they were everyday people who placed extraordinary value on the approval of authority figures, even strangers.
Milgram discovered that one variable affected behavior more than any other: the presence of just one more person. If a confederate administered the full 450-volt shock, compliance jumped from 65% to 90%. Conversely, if one person refused to continue, compliance plummeted to just 10%. This reveals that harnessing social support sometimes requires finding just one respected individual willing to model new, healthier behaviors.
While respected individuals like formal leaders can significantly influence behavior, influencers must also engage a second critical group: opinion leaders. Dr. Everett Rogers discovered this truth when trying to convince Iowa farmers to adopt new corn strains. Despite the clear benefits of these strains, farmers rejected Rogers' recommendations because he wasn't "one of them." When he convinced an innovative farmer who wore Bermuda shorts and drove a Cadillac to try the new corn, other farmers still resisted because this "innovator" wasn't respected either.
Rogers' research revealed that an innovation's merit doesn't predict adoption-what matters is who embraces it. The key is finding opinion leaders (about 13.5% of any population) who are smart, open to new ideas, but crucially, socially connected and respected. The remaining 85% won't adopt new practices until these opinion leaders do. This explains why successful influencers like Dr. Berwick at IHI engage medical "guilds" first, and why Donald Hopkins always works through village chiefs when fighting Guinea worm disease. As Hopkins notes, "The message is no more important than the messenger."
When creating change, you don't need to influence everyone simultaneously-just focus on the opinion leaders who influence everyone else. In a company of 10,000, concentrate on the 500 or so opinion leaders. These individuals will always be engaged in your change efforts whether you want them to be or not, as they naturally observe and judge your ideas before giving them a thumbs-up or thumbs-down that others follow.
To become an effective influencer, aspire to be an opinion leader in your work and family circle. Opinion leaders possess two crucial qualities: they're knowledgeable about relevant issues and they're trustworthy-people believe they have others' best interests at heart. But being respected isn't enough; opinion leaders are generous with their time, frequently interacting with those who look up to them and speaking their minds directly. When examining factors contributing to employee satisfaction with bosses, the best predictor was frequency of interaction. Accessible bosses who talk openly and spend informal time with direct reports are far more influential than distant ones.
When problems stem from long-held, widely shared norms, everyone needs to discuss the changes before anyone can successfully act in new ways without facing ridicule. However, some norms are considered taboo or politically incorrect to discuss openly. The key to creating change in such cases is finding ways to partner with opinion leaders to make the undiscussable discussable. By transforming taboo subjects into routine parts of public discourse, you gain an enormously powerful tool for addressing the toughest challenges.
Capitolo 9
Building Social Capital: Finding Strength in Numbers
Beyond motivation, social capital provides ability-access to others' brains, hands, and resources. As James Surowiecki explains in "The Wisdom of Crowds," groups often outperform even the smartest individuals. When 787 people at a livestock fair guessed an ox's weight, their average guess of 1,197 pounds was just one pound off the actual 1,198 pounds. Muhammad Yunus applied this principle by having village women who knew their community's needs collaborate on business plans, creating solutions no individual could devise alone.
While some change efforts obviously require teamwork (like reducing hospital deaths), others seem individual but still benefit from social support. Clever influencers always consider how to provide social backing for crucial moments of choice.
At a software company plagued by "project chicken"-where team leaders lied about being on schedule hoping someone else would admit delays first-the new VP discovered that individual training wasn't enough. The lying was reinforced by managers at all levels. His solution? Have the same managers who had subtly encouraged deception teach courses on speaking up about problems. Within months, candor flourished, and within a year, the company launched products on time and on budget.
For personal challenges like Henry's weight loss efforts, success often requires turning "disablers" into "enablers." When Henry asked his wife to stop buying chocolate, she laughed-she enjoyed candy without gaining weight. Yet research shows people achieve greater cholesterol reduction when spouses participate in the program.
When facing changing or turbulent times requiring novel solutions, multiple heads prove better than one. Dr. Yunus ensures his microcredit clients always work, think, and brainstorm as teams, counting on synergy through forced interaction. By demanding group problem-solving, Grameen Bank harnesses collective creativity that individuals working alone could never generate.
Those facing the biggest risks draw most heavily from social capital to reduce vulnerability. Dr. Silbert's Delancey Street Foundation transforms hardened criminals into productive citizens through an intricate web of peer relationships. Former thieves now work as movers entering people's homes-with zero theft incidents. Recovering addicts serve alcohol in restaurants-with virtually no relapses.
Some challenges require the most powerful form of social capital-solidarity-where individuals sacrifice personal interests for collective benefit. Dr. Wiwat applied this principle to combat HIV/AIDS in Thailand. His solution required complete solidarity-if even one sex worker accepted payment for unprotected sex, clients would simply go elsewhere. By gathering all business owners and workers to explain the economics and health consequences, he secured universal commitment. When every worker demanded protection, compliance rates jumped from 14% to over 90%, ultimately sparing an estimated 5 million people from HIV/AIDS.
Capitolo 10
Designing Rewards and Demanding Accountability
Moving beyond personal and social factors, effective influencers also leverage structural motivations like rewards, perks, bonuses, and accountability systems. The authors emphasize that extrinsic rewards should be the third strategy employed, not the first-only after ensuring vital behaviors connect to intrinsic satisfaction and securing social support.
Using rewards as your first motivational strategy often backfires. Dr. Mark Lepper's famous nursery school study demonstrated that rewarding children for activities they already enjoyed actually decreased their interest once rewards were removed-the "over-justification hypothesis." When people receive rewards for enjoyable activities, they may conclude they're only doing it for the bonus, not the inherent satisfaction.
Despite potential pitfalls, influence masters do employ rewards and punishments effectively. The key is ensuring rewards come soon, are gratifying, and clearly connect to vital behaviors. Even small rewards can help overcome persistent problems when properly structured.
At Johns Hopkins Hospital, alcoholics learning to drink moderately were given privileges (better food, phone access, visiting hours) based on controlled consumption-making them 60% more likely to reach target levels than those simply given instructions. Similarly, Dr. Stephen Higgins found that simple vouchers for goods and services helped cocaine addicts stay in treatment programs (90% completion versus 65% without vouchers).
Small rewards work best when they build on existing personal and social motivation. At Delancey Street, Mimi Silbert masterfully uses incremental privileges-from better housing to "walk-around money"-to reinforce progress. The key is making rewards proportional and meaningful rather than excessive.
Most workplaces fail to recognize incremental improvements, despite employee surveys consistently showing that lack of recognition is their top complaint. Unlike how we enthusiastically praise children's small achievements, at work we often wait for extraordinary accomplishments before offering recognition. Instead, we should reward small improvements in vital behaviors along the path to results.
Rewarding results without considering behaviors can backfire dramatically. When a Texas production facility celebrated a record-setting assembly day, they discovered the achievement came through cutting quality standards, depleting stock for the next shift, and deliberately underperforming the previous day. Leaders must ensure they're rewarding both the right results and the right behaviors that produce them.
Organizations often inadvertently reward exactly the wrong behaviors. Coaches preach teamwork while celebrating individual accomplishments; families enable addiction while claiming to oppose it; and national policies incentivize spending over saving through tax structures. When behaviors are problematic, examine your reward system-it may be causing the very problems you're trying to solve.
Capitolo 11
Changing the Environment: The Power of Things
Our environment-the world of buildings, space, sound, and sight-represents the third source for increasing our ability to perform vital behaviors. This structural approach to influence can be remarkably effective, as demonstrated by William Foote Whyte's classic intervention in the restaurant industry.
In the late 1940s, Professor William Foote Whyte was called in to address growing conflicts in restaurants. Post-WWII prosperity had Americans eating out in unprecedented numbers, while returning GIs displaced women as cooks, creating tension. Waitresses would shout orders, cooks would respond with hostility, and revenge-taking led to incorrect or delayed orders. Rather than addressing this through interpersonal skills training or pay changes, Whyte's genius solution was environmental: a simple 50-cent metal spindle for written orders that eliminated face-to-face confrontations, established a clear process sequence, and immediately decreased conflict.
We rarely think of changing the physical world to change behavior. Caught up in human dynamics, we miss the impact of subtle yet powerful environmental factors-making the physical environment one of our most powerful but least used sources of influence. Most of us are "environmentally incompetent."
Brian Wansink's clever experiments demonstrate how small environmental changes dramatically affect behavior. People given large buckets of stale popcorn ate 53% more than those with smaller buckets, despite being full from lunch. With his "bottomless soup bowl" experiment, people ate 73% more soup without feeling any fuller-waiting for visual cues rather than internal signals. Wansink suggests people make over 200 eating decisions daily without realizing it. These mindless choices add hundreds of calories without adding satisfaction.
Information profoundly affects behavior, yet we're often unaware of how incomplete data streams shape our perceptions. We typically can name only 2-4 global conflicts when dozens exist, because media coverage determines our awareness. Similarly, we incorrectly assume homicides outnumber suicides because homicides receive more news coverage. Influence masters deliberately manage data streams to drive vital behaviors.
Physical proximity (propinquity) profoundly shapes human relationships in ways we rarely notice. Leon Festinger discovered that apartment dwellers near stairwells or mailboxes know more neighbors than others. Corporate relationships improve when people work physically closer together, while distance breeds distrust and "us versus them" mentalities.
Smart creatures use tools to make difficult tasks easier. While Frederick Taylor revolutionized industrial efficiency by designing task-specific tools, these engineering principles haven't always been applied to complex social problems. Influence masters change things rather than constantly motivating people to perform difficult behaviors.
The most powerful environmental changes eliminate human choice entirely, making good behavior inevitable rather than merely easier. Engineers build safety features into machines that physically prevent injuries. Fast-food restaurants use picture buttons and automatic change-counting to routinize tasks that once required skill.
For complex social problems, we can make positive behaviors inevitable by structuring them into daily routines. One CEO dramatically increased innovation by scheduling regular meetings with employees specifically to solicit ideas. At Delancey Street, Silbert uses "Games"-a ritual held three times weekly where residents can confront anyone about anything. This structured feedback system prevents the typical toggle between silence and verbal explosions, making constructive confrontation inevitable rather than optional.
Capitolo 12
Becoming a Master Influencer: Combining the Six Sources
Effective influence begins with identifying the right behaviors to target. Dr. Ethna Reid's approach teaches us to look for best practice research that compares top performers to others, identifies the unique behaviors that differentiate them, and then tests whether teaching these behaviors to others improves their performance.
When evaluating potential influence strategies, demand scientific rigor. Search university publications, frequently cited research, and work from renowned practitioners who publish their results in respected journals. After identifying behaviors that have worked for others, apply positive deviance by examining when you've succeeded personally and identifying what led to your success. Test these behaviors through short-cycle mini-experiments before committing to long-term plans.
Behind each vital behavior lie six distinct sources of influence. Sometimes adding just one missing source can put your change strategy over the top. You might build deliberate practice into helping children love reading, add social reinforcement to corporate training, or move exercise equipment from the basement to your bedroom to overcome propinquity. The right combination of influence concepts can provide the extra horsepower needed to create lasting change.
Skilled influencers diagnose before prescribing solutions. Rather than throwing together generic strategies, they identify which sources of influence drive current behaviors. Dr. Warren Warwick exemplifies this approach with his cystic fibrosis patients. When an 18-year-old wasn't following her treatment plan, he didn't lecture her about consequences. Instead, he uncovered multiple barriers: she had a new boyfriend, was staying away from home where her mother typically administered treatments, was working nights, and faced school policy changes requiring nurse administration. Despite losing 20% of her lung capacity, she felt fine and thought fewer treatments were acceptable. By understanding these multiple influences, Dr. Warwick and his patient developed a life-saving plan.
When behaviors are supported by multiple sources, you need a comprehensive influence strategy. The world is perfectly organized to create your current results, and achieving new ones requires changing multiple elements.
People often try to implement change on the cheap, selecting just a few elements from comprehensive strategies like cafeteria items. This happens with corporate leaders seeking cultural change and with visitors to Delancey Street who hear Dr. Silbert's comprehensive approach but implement only one idea. Similarly, police departments adopt only pieces of North Carolina's successful second-chance program, then wonder why their efforts fail. Effective change requires addressing all six sources of influence rather than cherry-picking elements.
Ineffective influencers rely on a single source of influence-often threats or extrinsic rewards-and try to amplify it when it fails. Savvy influencers instead tap additional sources. With motivation problems, they align multiple motivational sources with desired behaviors. With ability problems, they recognize that one barrier can trump all enablers, so they must address multiple disablers.
Effective influencers overdetermine vital behaviors to make change inevitable. They examine all six sources, implement methods from each, and continue adding new influence strategies long after others have given up. They do this because the changes they're attempting are often so audacious that they require every available influence tool.
The book began with a bold claim: by combining the right influence techniques into a comprehensive strategy, you can change virtually any human behavior. The evidence comes from real-world success stories like Delancey Street, where Dr. Mimi Silbert transforms 90% of habitual criminals into productive citizens; Dr. Don Berwick's 100,000 Lives Campaign that reduced hospital deaths by 122,000 in 18 months; and The Carter Center's near-eradication of Guinea worm disease across sub-Saharan Africa.
These influencers succeeded where others failed not because they cared more or spent more money, but because they mastered the science of influence. They demonstrate that ordinary people can become master influencers by learning to build comprehensive influence strategies rather than tinkering with isolated techniques.
