Chapter 3: Trust the Incentives
Frank Egan was San Francisco's first public defender. A former police officer, he took the job in 1921 when the office was one lawyer and no staff, and built it into an office of more than a dozen. He was popular enough that David Talbot describes him as "a man widely considered to be a future mayor."
Weeks after Jessie Hughes's death, standing in front of reporters, Egan wept. "Mrs. Hughes has been like a mother to me," he said.
Hughes was a fifty-nine-year-old widow and former client. Trusted to manage her finances, Egan had taken her money and mortgaged her property without telling her, and he had made himself the beneficiary of her will and several life insurance policies. When she discovered it and threatened to report him to the State Bar, he decided the cheaper option was to have her killed.
On the night of March 29, 1932, two men knocked her unconscious in her own home, dragged her into the garage, ran her over with a borrowed car, and left her body in the street to look like a hit-and-run. Both men were ex-convicts on Egan's payroll: one his bodyguard, the other an employee of the public defender's office. The staging wasn't only to deflect suspicion. One of the policies paid double for an accidental death.
When one of them confessed, Egan ran. For days the most notorious criminal in San Francisco was the city's own public defender, and he had not yet been charged with anything. He was caught, convicted of first-degree murder, and served twenty-five years before his parole in 1957.
Nothing about Egan was hidden. He held public office. He was surrounded every day by lawyers, investigators, and judges. Eleven years of visible competence had earned him the trust he had. The trust was real. It should never have been complete.
The lesson is old. When John D. Rockefeller was a boy, his father used to play a game with him. He would stand him on a high chair and tell him to jump, promising he would catch him. One day, young John leapt off the chair with full confidence and his father stepped aside, letting him crash to the floor. As John scrambled to his feet, astonished, his father looked at him and said: "Never trust anyone completely. Not even me." It was a brutal lesson, but Rockefeller never forgot it.
Leonardo da Vinci wrote in his notebooks: "He who never puts his trust in any man will never be deceived." That is not a practical way to live. You can trust some people a great deal. But the operative word is completely. In the end, you can only trust people whose incentives align with yours.
The goal isn't paranoia. The goal is calibration.
And calibration starts with an unglamorous fact: betrayal is rare. Daniel Ek, the CEO of Spotify, reflected in a conversation with David Senra that only about one or two percent of people in his life had ever broken his trust. Senra himself couldn't think of a single person who had betrayed him in the past two decades. They are disciplined selectors. They understood early that character is revealed, not reformed, and they built their circles accordingly.
That is the real shape of the problem. Betrayal is uncommon, catastrophic when it arrives, and almost entirely a function of who you allow close and on what terms. What follows is a catalogue of what it looks like when it happens. Read it as a guide to selection, not as evidence that everyone is coming for you.
Institutions
Businesses
In the early 2000s, a retired British policeman named Jim McCormick manufactured a device called the ADE 651 and sold it to governments as a bomb detector. It was essentially a dowsing rod. As Iraq descended into sectarian violence after 2003, the Iraqi authorities purchased 5,000 units and deployed them at road checkpoints. They never worked. The false reassurance they gave almost certainly contributed to many deaths. On the profits, McCormick bought a three-million-pound house in Bath, a yacht, and a string of horses. He insisted throughout his trial that the devices operated on "nuclear quadrupole resonance theory." He was sentenced to ten years in prison. The fraud was crude enough to be obvious in hindsight and dressed well enough that nobody checked.
In the early 1980s, Bayer's Cutter Biological division sold a clotting agent to hemophiliacs that was contaminated with HIV. When Cutter developed a safer version, it stopped selling the contaminated product in the United States under FDA pressure, but continued selling the old unsafe inventory overseas for months to countries including Argentina, Indonesia, and Japan. Internal documents revealed the reason: Bayer wanted to avoid financial losses on remaining stock.
Thousands of hemophiliacs were exposed to HIV. No executives were criminally charged. The full story only emerged when the New York Times investigated in 2003, two decades after the decision was taken, by which time the men who died from it were long buried and the company had absorbed the episode as a cost of doing business.
Eduardo Saverin co-founded Facebook alongside Mark Zuckerberg, contributing early capital and his name to the incorporation documents. Then came the dilution. As new investment rounds were structured, his stake was cut from roughly 34 percent to under 10 percent through share issuances he claims he did not fully understand when he signed off on them. He sued, and a confidential 2009 settlement restored him to around 5% and to his co-founder title. He became a billionaire at the IPO.
That last part is what people forget. Saverin was not destroyed. He was a founder holding a third of a company and years of shared history with the man running it, and he still needed litigation to recover a sixth of what he had started with. Goodwill is not a legal instrument. Neither is trust. Before you sign anything, get a lawyer, not because you expect bad faith, but because the documents will outlast the relationship.
Money Managers
The easiest fraud in the world is one where the victim wants to be deceived.
Bernie Madoff understood this better than anyone. For decades, he told clients he was running a hedge fund. He was not. He took their money, deposited it in a bank account, and mailed out statements showing handsome returns. When the SEC investigated him, Madoff fabricated the records, dressing up forgeries as evidence. The agency found no fraud and closed the case. The scheme ran until 2008. When it collapsed, the statements showed $65 billion in assets that did not exist.
The tell is always the same: returns too consistent, documentation too elusive, explanations too smooth. These frauds differ in scale, not in kind, and the kind is legible to anyone willing to ask for documents and to keep asking when the answers come back polished and incomplete.
Not every investment manager is a criminal. But the industry's own incentives work against you. Charlie Munger knew an investment manager, a smart and capable one whom he declined to name, who told institutional clients he expected to earn them 20 percent annually. Munger was stunned, knowing such returns were impossible to sustain. The manager's response was alarming: "Charlie, if I gave them a lower number, they wouldn't give me any money to invest." Munger concluded that the entire fee-driven business was irrational: "Everyone wants to be an investment manager, raise the maximum amount of money, trade like mad with one another, and then just scrape the fees off the top." The reason managers are reckless with your money is simple. It is not their money. If a leveraged bet pays off, the manager collects enormous fees. If it fails, the client absorbs the loss.
One data point removes all ambiguity about where fund managers' true confidence lies. In a 2009 Morningstar study tracking over 4,300 actively managed mutual funds, 49 percent of fund managers owned no shares in the funds they managed. Nearly half. Of the remaining managers, most held only token amounts relative to their compensation and net worth. When the people running the fund won't put their own money into it, the question answers itself. As Buffett wrote: "When trillions of dollars are managed by Wall Streeters charging high fees, it will usually be the managers who reap outsized profits, not the clients."
Even advisors acting in good faith may not owe you what you assume they owe you. Until 2020, brokers were held to a "suitability" standard: a recommendation only had to be broadly appropriate for your situation at the time it was made, regardless of who benefited more from it. Regulation Best Interest replaced suitability in June 2020 and requires brokers to weigh reasonably available alternatives, which is a real improvement, but it remains narrower than a fiduciary duty. And a fiduciary with poor judgment or limited product access can still hand you expensive, mediocre advice while perfectly honoring their legal obligation. The standard governs intent, not competence.
Cryptocurrency runs the same machinery on newer rails. The people who lost their savings to Celsius lost them slowly, through a series of reassurances: high interest rates, professional marketing, a CEO who appeared on YouTube every week to answer questions. Alex Mashinsky built a reputation on transparency. In May 2022, weeks before Celsius froze all customer withdrawals, he allegedly withdrew $10 million of his own funds from the platform. Customers had no idea. One of them later wrote to the bankruptcy court: "I have a mental disorder and I cannot sleep now." At FTX, co-founder Gary Wang reportedly coded a back door into the exchange that allowed funds to be drained without triggering any alerts, while the platform kept accepting deposits and projecting confidence.
Madoff's clients weren't stupid people. Celsius depositors read the disclosures and watched the weekly broadcasts. The problem was never intelligence. It was trust placed without verification, and the oldest truth on Wall Street left unexamined: when someone needs your money to make you rich, always ask first how they plan to make themselves rich in the process.
Doctors
Peter Attia graduated from Stanford Medical School, trained at Johns Hopkins, and was, by any measure, exactly the kind of doctor the system was designed to produce. Late in his second year of residency, he had a patient in the ICU dying of sepsis, kept alive by a drug called gentamicin. The drug has a narrow therapeutic window: too little and it fails; too much and it destroys the kidneys and hearing. Attia, the self-described math geek, built a model and calculated precisely when the next dose was needed: 4:30 a.m. When the time came, his superior told him to wait until the next nursing shift at seven, leaving the patient unprotected from a potentially fatal infection for two and a half hours, for no medical reason. Attia had the nurse give the dose anyway.
The next morning, he was screamed at and threatened with termination.
Not for harming the patient. For helping him.
That moment cracked something open. What Attia found underneath was a culture so entrenched in its own traditions that it could not change even when lives depended on it. Dr. Paul Conti, a psychiatrist who entered medicine with similar idealism, arrived at the same conclusion from a different direction: "When I first made the career shift to medicine, I expected health care to be organized with patients in mind. Wow, was I ever surprised. The healthcare system doesn't seem to care much about what happens to patients outside of the hospital or clinic, and it doesn't do that great a job when they're inside, either." What both men discovered is that the system is not indifferent to patients out of malice. It is indifferent to patients by design.
The clearest way to understand any system is to follow the money. Attia traces it: health insurance will not pay a doctor much to help a patient change their diet and prevent type 2 diabetes, but it will cover that same patient's insulin after the diagnosis arrives. There is no billing code for the exercise program that keeps an aging patient from falling, but their hip surgery and physical therapy are fully covered. Nearly all the money flows to treatment, not prevention. The architecture of the system does not reward keeping you well. It rewards you getting sick.
Nassim Taleb offers a useful heuristic: never ask the doctor what you should do. Ask them what they would do if they were in your place. The gap between those two answers will tell you everything. The doctor, Taleb notes, is trying to minimize their personal risk, specifically the lawsuit. A life saved is a statistic, invisible and unaccounted for. A person harmed by a side effect is an anecdote, and the lawyers will come. So the doctor prescribes defensively, cautiously, in ways that protect their career first.
Even a doctor acting in perfect good faith is constrained by the boundaries of their training. Attia is candid about what medical school, including Stanford's, does not teach: "We learned next to nothing about exercise, nutrition, sleep, or emotional health." Those four are the foundational pillars of how long and how well you live. The system trains physicians to treat disease once it has arrived, not to prevent it from arriving at all.
None of this means you refuse treatment or reject medicine wholesale. It means you walk in with your eyes open. The person across the desk has real expertise and, in most cases, genuine intentions. But their training has gaps, their incentives are not aligned with your long-term health, and the institution backing them was not designed with you as the primary concern.
Governments
The record here is not subtle. "Governments keep their promises," Napoleon observed in 1817, "only when they are forced or when it is to their advantage to do so." He knew this because he had run one.
In 1932, Charlie Pollard was a twenty-six-year-old farmer in Macon County, Alabama, living in a wooden shack with no furniture, sleeping on rags. When word spread that the government was offering free medical exams to African-American men, he joined the line outside the local schoolhouse. He had never seen a doctor before. A worker told him it was just a blood test. Days later he was informed he had "bad blood," a vague local term for various ailments, and that he qualified for a government treatment program: free care, free rides to the clinic, a hot meal on examination days, and fifty dollars for his family if he died and agreed to an autopsy. He signed up. About 400 other men did the same.
Then came the spinal taps, performed without warning, excruciatingly painful, leaving the men bedridden for weeks. Within a year, rashes spread across their bodies, bones ached, hair fell out, fevers came and didn't leave. Some developed tumors. Some went blind. Some died. The men stayed convinced the program was helping them, because no one told them otherwise. In July 1972, forty years after Charlie had stood in that schoolhouse line, Peter Buxtun, a venereal disease investigator who had spent six years trying to stop the study from inside the Public Health Service, leaked the documents to the Associated Press. Jean Heller broke the story. The Washington Star ran it on the front page: "Syphilis Victims in United States Study Went Untreated for 40 Years."
"Bad blood" was a fiction, invented to keep the men from asking questions. They had syphilis, and the government had never intended to treat it. The program existed to observe what happens when syphilis goes untreated for a lifetime. When penicillin became the cure in the 1940s, researchers hid it from the men and blocked them from seeking outside care, to avoid contaminating the results. Macon County was chosen because its population was poor, uneducated, and easy to deceive. At least twenty-eight men died directly from the disease. Charlie, then sixty-seven, learned his syphilis had burned out on its own. He and the seventy-three other survivors were each awarded $38,000 in an out-of-court settlement. He died in 2000, at ninety-four.
It would be comforting to call Tuskegee an aberration. It's not. "In every age," the historian Will Durant wrote, "men have been dishonest and governments have been corrupt." The specifics change. The structure remains.
In 2013, Edward Snowden revealed that the NSA had built a surveillance apparatus of staggering scope, tapping directly into the systems of major telecommunications providers and corporate platforms, harvesting emails, voice chats, photos, and social networking data. The program was governed by secret courts, and the public had no knowledge of it and therefore no means to contest it.
Whenever given the opportunity, governments grant themselves crisis powers and then quietly extend them indefinitely. The Patriot Act passed in the immediate aftermath of 9/11, at the peak of public grief, and expanded surveillance authority in ways that persisted long after the emotional moment that justified it. As Lyn Alden, who writes on monetary systems, observes: "decade after decade, event after event, this centralizing tendency chips away at individual rights to privacy and begins to shape culture to align with the idea that people who want privacy must be up to something bad."
The counterargument is always the same: these scandals came out. Snowden leaked. Tuskegee was exposed. If governments were capable of hiding things, wouldn't we know less than we do?
The Manhattan Project answers that. Thousands of people worked across multiple secret sites for years to develop the atomic bomb, and the public knew nothing until the first one fell on Japan. What we know about is what someone eventually chose to expose, or what governments could no longer contain. That is not the same as everything.
As Alden concludes: "People should assume that virtually all information about them is collected into corporate databases, that their government can access those databases, and that the databases are vulnerable to external breaches. Your sensitive personal data has most likely been leaked multiple times, and is easily accessible to intelligence analysts as part of their surveillance apparatus."
You are not the customer of most institutions that hold your information. You are the inventory. And inventory does not get to choose where it is stored.
Trust institutions where you must, and verify where you can. History does not reward naivety, and governments, as Napoleon knew firsthand, do not keep promises out of virtue.
People With Access
Bosses
The people who hold power over your career will smile, promise, and deliver, right up until the moment it becomes inconvenient for them to keep doing so. You will recognize the arrangement before it costs you or after. Those are the options.
Jennette McCurdy agreed to carry a television show for one reason: she was promised the chance to direct an episode. She showed up every day, swallowed her frustrations, and delivered three dozen episodes of professional work. Then the promise evaporated. A senior crew member threatened to quit if she directed, and management chose the crew member. "I've been foolish," she wrote. "I believed that these people would do what they said they would. Now that they've gotten what they wanted out of me, they're taking away the very reason why I was doing all of those things in the first place." Nothing about it was accidental. She had already given them what they needed.
Sam Bankman-Fried ran the same play, except his version was encoded in a contract. FTX employees held tokens in Serum, a cryptocurrency project the company had helped create, as part of their compensation. When Serum's price skyrocketed and his staff felt rich, their motivation to grind fourteen-hour days quietly diminished. Sam extended the lockup period on all employee Serum to seven years, using a clause he had buried in the fine print from the beginning. Ramnik Arora, an FTX executive who had bought tokens with his own money before joining, watched the rules change mid-game. "I guess you would know in seven years," he said. You don't own what you think you own, and the person setting the terms can reset them whenever the math shifts in their favor.
The same dynamic operates sideways, among peers. When Nancy Pelosi ran for chair of the Democratic National Committee in 1985, the people who turned against her weren't outsiders or opponents. They were colleagues she had worked alongside for years and actively helped. "These are people that I knew, that I worked with all the time, that I'd helped so much," she later said, "and all of a sudden they had turned on me." She lost. The experience didn't break her, but she never again confused familiarity with loyalty.
Get the promise in writing. Read the fine print. Not the summary they hand you—the actual document. Understand what you receive and exactly when you receive it. Your value to an organization is highest before you have fully delivered. Use that window. Because once they have what they came for, the promise becomes a liability on their books, and liabilities have a way of getting quietly written off.
The People Closest to You
There is an old Turkish proverb that captures something people spend their entire lives refusing to accept: "When the axe came into the forest, the trees whispered, 'The handle is one of us.'"
The previous pages dealt with institutions and the people who represent them—governments, employers, money managers, physicians. The threat that should concern you most is not the one approaching from the outside. It is the one already sitting at your table, sharing your last name, sleeping in your bed.
Nassim Taleb wrote: "The worst pain inflicted on you will come from someone who at some point in your life cared about you." Not someone who hated you. Not an enemy. Someone who cared. The proximity that creates love also creates leverage. The person who knows your fears, your weaknesses, your secrets, your ambitions, is not only positioned to support you. They are positioned to undo you.
Mariah Carey's memoir makes the point about blood. She writes that her sister and brother put her "on the chopping block," and "sold lies to any gossip rag or trashy website that would buy or listen" for decades. The worst offense came early: when Carey was twelve, her sister drugged her with Valium, offered her cocaine, inflicted third-degree burns, and attempted to sell her to a pimp. Today, Carey refers to her brother as "ex-brother" and her sister as "ex-sister." The titles of family were stripped because the behavior that earns them was never there.
None of which makes such people villains. It makes them human, and humans act first in the service of their own survival and desire. Circumstances change, resentments accumulate, ambitions diverge. Pfeffer's counsel is to live without naivety rather than in suspicion: "Be prepared, so when bad, unfair things happen, you are not surprised and can respond effectively, strategically, and as unemotionally as possible." The person blindsided by betrayal from someone they loved is wounded twice, once by the act and once by the shattering of their illusion. Remove the illusion in advance, and the wound, when it comes, becomes survivable.
Trust has nothing to do with bloodline. It is a conclusion drawn from observed behavior over time. The person who has dealt fairly with you across years, who has given you the better end of arrangements when they didn't have to, who has never leveraged your trust against you: that is who has earned a place in your inner circle. The criterion is character demonstrated through consistent action, nothing else.
Trust selectively. Love fully, but never confuse closeness with safety.
Romantic Partner
Belle Burden was a successful attorney from a wealthy family. Her husband James was the same. They had three children, a beautiful home, a marriage she described as intimate and emotionally steady from the first day to the last. James planned their trips, took their son to hockey practice at five in the morning, and kept a black-and-white composition book where they rated soup dumpling restaurants in Chinatown. He carved their initials into fallen trees, named boulders in the forest after each child, and spoke openly about the paths he was tending so he could walk his daughters to the lake for their future weddings. He told Belle he loved her every day. He asked her often, "I make you so happy, right?" When they heard about other couples' infidelities, he reassured her they were different. Quiet, cerebral, compatible. He never once told her he was discontent.
Then one afternoon, a voicemail arrived from a stranger. His wife had been having an affair with James. It had been going on for a month. That same day, James told Belle he wanted a divorce, relinquished custody of their children, and flew out the next morning to be with the other woman, who was fifteen years younger and looked nothing like Belle.
What followed was not just emotional devastation. It was financial demolition. She had purchased two homes using money from her family trust, and in a gesture of good faith, had placed them in both her name and James's. Their prenup stipulated that joint assets would be split evenly. Meanwhile, James had spent years accumulating millions at a hedge fund, all in his name alone, and Belle had no knowledge of it because he handled all their finances. She had given him everything in good faith. He had quietly, methodically, kept everything that mattered to himself.
His lawyer's letter arrived in early August. She could buy James out of both properties or sell them, and she could not afford to buy him out. "My children were going to lose the house they loved, the center of our life as a family," she wrote. "There was no reason for it, given James's resources. It felt like he was playing a game, or running a deal, one he was going to win at all costs, by a wide margin, regardless of the impact on me and our children."
The same shape runs through every story of this kind. The person who made you feel most secure is often the one operating with the most information, the clearest exit strategy, and the least accountability. Belle didn't lack intelligence or instinct. She was a trained attorney. She trusted completely, and in her despair she couldn't read, couldn't write a simple email, broke down over scanning signature pages into documents. There is a proverb for this: "The day a blind man sees, the first thing he throws away is the stick that has helped him all his life." Trust, when it becomes total, becomes dependency. And dependency, in a crisis, looks a great deal like helplessness.
Maintain your own financial literacy, your own legal standing, your own awareness of the architecture of your life. James knew exactly where the money was. He knew what the prenup said. He had, whether consciously or not, built a structure in which he held all the high ground. Belle had built a life of good faith and placed it entirely in his hands.
Love and strategic self-protection are not in conflict. They never were. You can love someone completely and still read the prenup. You can trust a partner deeply and still understand your own finances. The mistake is not in loving. It is in using love as a reason to stop paying attention.
What To Do
Choose, Don't Fix
People rarely change fundamentally. They accumulate experiences, absorb consequences, maybe soften a few rough edges, but the core remains. Ray Dalio, after decades of watching people operate inside one of the world's most demanding organizations, wrote: "Remember that people typically don't change all that much."
The common mistake is assuming that bad behavior is correctable through exposure to better information or harsher consequences. It rarely is. Bad behavior typically grows out of false beliefs, and the reason those beliefs are so durable is that the person holding them doesn't experience them as beliefs at all. They experience them as facts. Reality, as they understand it. You cannot argue someone out of a position they don't know they're standing on. This is why Nassim Taleb's observation cuts so deep: "You can only convince people who think they can benefit from being convinced." Few people are willing recipients when it comes to their own character.
Robert Greene codified the warning in Law 10 of The 48 Laws of Power: avoid the unhappy and the unlucky. "You may feel you are helping the drowning man," he writes, "but you are only precipitating your own disaster." Emotional states spread the way diseases do, quietly and without your consent. Work by Rosenquist, Fowler and Christakis on three decades of Framingham Heart Study data found that when a woman's close friend becomes depressed, her own probability of depression rises by 142 percent. The same study found no significant effect from a depressed male friend, a limit that belongs with the statistic.
To identify who needs to go, forget the history and forget the excuses. Is this person good or bad right now, today? If they are bad today, cut them out. It doesn't matter if it's a parent, a sibling, a lifelong friend. If they're good today, ask honestly whether you can forgive the past. If you can't, still cut them out, because resentment will poison whatever you try to build going forward.
Watch how people behave when their guard is down. Drunk actions are sober thoughts. The person who becomes cruel after a few drinks isn't showing you a different version of themselves. They're showing you the one they normally keep hidden.
Stay away from anyone with a bad reputation. There are more than enough good people with demonstrated track records, and the person with the bad reputation might be the rare exception, but that is a bet with terrible odds and no good reason to make it. Cutting someone out doesn't require hatred. You can miss something and not want it back. Healing doesn't mean reconnecting with the people who hurt you; it means carrying forward the lesson without carrying forward the person.
One category deserves separate mention. Balaji Srinivasan draws the distinction: "Good people help others with no concern for themselves. Smart people help others while also helping themselves. Evil people hurt others to help themselves. Dumb people hurt themselves and others." The dumb person is the only actor in that taxonomy with no redeeming outcome. Evil, at least, has a logic to it, a self-interest you can track and anticipate. Dumb is pure waste, corrosive in all directions, including inward.
Alex Hormozi offers the cleanest test for all of it: "If you disappeared, would my life get better?" That question cuts through every rationalization and every sentimental attachment.
Trust Yourself
No one is coming to rescue you. Not your doctor, your mentor, your financial advisor, or your closest friend. They are not villains; they simply cannot care about your outcome the way you do. Naval Ravikant states it without qualification: "Doctors won't make you healthy. Nutritionists won't make you slim. Teachers won't make you smart. Gurus won't make you calm. Mentors won't make you rich. Trainers won't make you fit. Ultimately, you have to take responsibility. Save yourself."
It is tempting to treat trust as a switch, either fully on or fully off. That instinct is a trap. It makes you both naive and unnecessarily isolated, oscillating between blind faith and paranoid withdrawal.
The more useful frame is to ask not do I trust this person, but in what ways do I trust this person? A colleague might be brilliant at analysis and terrible at keeping a secret. A friend might show up for you emotionally every time and be a disaster with money. You do not need to distrust someone to keep certain information to yourself. You only need to see things clearly.
You can delegate tasks. You can lean on expertise. What you cannot do is outsource your judgment or your final accountability. Those belong to you alone, because no one else has the same stake in the outcome.
The people who thrive are not the ones who trust no one. They are the ones who know exactly what they are trusting each person with, and nothing more.
Win-Win Relationships
Which brings us to the part of this that looks like a contradiction and isn't. Everything above argues that other people's incentives diverge from yours. What follows argues that the most profitable way to operate is to make other people rich alongside you. Both are true. Win-win is not the opposite of distrust; it is what you build once you have stopped needing to trust. When the arrangement is constructed so that your partner does better by keeping their word than by breaking it, you no longer have to rely on their character. You have built a relationship that does not require faith to function, which is precisely why it lasts.
Many people approach business as a zero-sum game. There is a winner and a loser, and the only goal is to be the winner. They pull small advantages in every deal, squeeze every negotiation dry, and move on. What they don't realize is that this strategy, repeated over time, destroys the resource they're trying to accumulate.
The formal case for the alternative comes from Robert Axelrod. In The Evolution of Cooperation, he ran a tournament in which submitted strategies played repeated rounds of the prisoner's dilemma against one another. The winner was not the most aggressive program, or the most sophisticated. It was tit-for-tat, a few lines of code that cooperated on the first move and then did whatever its opponent had done last. Tit-for-tat never once beat an opponent head to head, and it won anyway, because exploitative strategies destroyed the relationships they fed on while tit-for-tat kept generating rounds worth playing.
Sam Zell built one of the most formidable real estate empires in American history, and he didn't do it by grinding every counterparty into the floor. "In any negotiation I believe in leaving a little bit on the table," he wrote, "and in any relationship I believe in sharing the stakes. I've been doing deals with many of the same people for decades because the goal is for us to all come out ahead." His employees stayed twenty and thirty years, because when he did well, they did well. Incentives aligned. Trust followed naturally.
Building relationships like this is a matter of construction rather than sentiment. Make the term long, because cooperation only pays when there is a next round and both parties know it. Make the stakes shared, so your partner's upside depends on your upside instead of being carved out of it. Make the accounting visible, because suspicion grows in exactly the places where people cannot see what they are owed. And leave something on the table every time, which is not generosity but pricing: the small amount you forgo is what you pay for the option to do this again.
The same construction tells you when to walk away. If a counterparty stands to gain more from defecting once than from cooperating for a decade, no amount of goodwill will hold the arrangement together. Structure the deal so that keeping the promise is the profitable move, or don't do the deal. The fix for misaligned incentives is not better people but better arrangements, and then, over years, noticing who behaves well even when they wouldn't have had to.
You can spot zero-sum thinkers quickly by how they talk about the people they do business with. They always have a grievance, a story about being owed something, a deal that went sideways. Win-win thinkers sound different. They say things like, "We've had a great relationship for ten years, they've always been good to us." That's the signal.
Rockefeller learned the other half first. The boy who was taught to trust no one, not even his father, built the largest fortune in American history and became, for a stretch, the most hated man in the country. He spent the last decades of his life trying to buy the reputation back, handing dimes to strangers and giving away hundreds of millions of dollars. The suspicion made him rich. It could not make him anything else.
The goal is not to do a great deal once. It's to find people you'd want to work with for the rest of your life, and then make sure they feel the same way about you.
