The Lottery Winner’s Paradox
In 1978, a University of Michigan psychologist named Philip Brickman finally tracked down the data that would confirm everyone’s worst suspicion about happiness. He had found二十二 recent lottery winners—ordinary people who had just been handed windfalls between $50,000 and $1 million, an astronomical sum in that era—and asked them bluntly: Are you happier now? The answer stopped him cold. These newly minted millionaires reported enjoying their morning coffee no more than they had before the check cleared. In fact, when Brickman compared them to a control group of non-winners, he found no significant difference in their day-to-day joy. The money had changed everything about their lives except the one thing they thought it would buy.
Brickman’s study, built on earlier work he had published with Donald Campbell in 1971, named the phenomenon that keeps fortune from translating into felicity: the hedonic treadmill. The metaphor is almost too perfect. Just as a runner must keep moving simply to stay in place, we humans must keep acquiring simply to maintain our current level of satisfaction. Buy the sports car, renovate the kitchen, finally snag the promotion—each victory provides a jolt of pleasure that feels permanent in the moment, yet chemically speaking, your brain treats it like a disturbance to be corrected. Within months, sometimes weeks, your emotional baseline reasserts itself. The car becomes «the car.» The raise becomes «the salary.» You’re running hard and getting nowhere.
The Happiness Thermostat
But why is the treadmill so difficult to escape? The answer lies deeper than habit or human folly; it is written, to a surprising degree, in your genes. In 1996, behavioral geneticist David Lykken proposed the idea of a happiness set point—a genetically influenced baseline toward which your well-being gravitates regardless of circumstance. Think of it like a thermostat set to 72 degrees. You can open the windows (win the lottery) or turn up the air conditioning (suffer a tragedy), but the system works tirelessly to bring the temperature back to its preset level. Lykken’s research suggested that while specific events might spike or crash your mood, the long-term trend line remains stubbornly consistent, determined largely by temperament and heredity.
This would be almost comforting if it weren’t so tragically misaligned with how we actually live. We organize our entire economies around the assumption that accumulation equals progress, that the next purchase will be the one that finally satisfies. Yet the treadmill mechanics suggest that material gains are uniquely ill-suited to moving the needle on our internal set point. They are external adjustments to an internal calibration system.
When Wanting Becomes Toxic
Here is where the story takes a darker turn. If the hedonic treadmill merely neutralized our pleasures—if buying things simply stopped working after a while—we might be forgiven for our consumerist habits. But recent research suggests materialism doesn’t just waste our money; it actively erodes our well-being.
A 2018 analysis by Bergler and Kauffman found that individuals who prioritize material wealth over relationships, community, or personal growth consistently report lower life satisfaction than their less acquisitive peers. This isn’t correlation without causation; the mechanisms are viciously clear. As psychologist Tim Kasser and others have demonstrated, materialistic goals tether your self-worth to comparisons you cannot control. When your happiness depends on having the newest phone, you are volunteering for a status competition against billions of strangers, many of them fictional avatars on social media platforms engineered to make you feel inadequate.
The financial costs compound the psychological damage. A 2012 study by Dittmann and Furr traced the link between materialistic values and chronic stress, finding that the pursuit of possessions often leads to unsustainable debt, workaholism, and the slow suffocation of leisure time. You buy the house to be happy, then work seventy-hour weeks to afford the mortgage, too exhausted to enjoy the backyard you supposedly wanted. The treadmill has become a hamster wheel, and you are paying for the privilege of running on it.
The Experiential Escape
So if the treadmill is genetic and materialism is poisonous, are we doomed to dissatisfaction? Not quite. The research reveals a crucial loophole in our psychology—one that suggests we have been spending our money on the wrong category of things entirely.
In 2013, researchers Mark Van Vugt and Igor Grossmann demonstrated that experiential purchases—travel, education, concerts, even challenging outdoor activities—produce more lasting satisfaction than material ones. The reasons are twofold. First, experiences resist the adaptation that plagues objects. Your new kitchen countertop is a static thing; you see it every day, and your brain quickly edits it out of conscious awareness. But a vacation in the Andes becomes part of your narrative identity. You tell the story, relive the moments, and with each retelling, the memory actually accumulates meaning rather than losing it.
Second, experiences are harder to compare. While your car can be directly weighed against your neighbor’s newer model, your solo hike or your cooking class exists in a category of one. Social media has done its best to ruin this advantage—Fardouly and colleagues noted in 2015 that platforms like Instagram transform experiences into performative commodities, triggering the same status anxiety that ruins material pleasure—but the underlying principle holds. When you buy an experience, you are purchasing identity, not inventory.
The Attention Diet
Yet even experiences won’t save us if we bring the same ravenous hunger to them that we bring to the shopping mall. The final piece of the puzzle involves not what we consume, but how we attend.
Psychologists Robert Emmons and Michael McCullough have spent decades studying gratitude as a psychological intervention—not as a feel-good platitude, but as a cognitive tool. Their 2003 research established that regular reflection on non-material blessings—relationships, health, nature, competence—literally retrains the brain to notice satisfaction rather than scarcity. It is an attempt to manually adjust the thermostat, if only by a degree or two.
This requires a kind of attentional discipline that runs counter to modern life. It means recognizing that social media, as Fardouly’s research suggests, functions as a comparison engine designed to accelerate your treadmill. Every scroll is a request to feel inadequate. Every targeted ad is a reminder of what you lack. Lasting happiness may depend less on buying experiences than on eliminating the digital environment that tells you happiness is always one purchase away.
The Culture We Can’t See
Before offering a tidy prescription, honesty demands a caveat: almost everything we know about the hedonic treadmill comes from Western, industrialized, capitalist societies. The research gaps are gaping. Does the set point theory hold in collectivist cultures where individual achievement is less central to identity? Does materialism poison happiness in communities where possessions hold spiritual rather than status value? We simply don’t know. The academic literature is impoverished when it comes to cross-cultural analysis, meaning our «universal» truths about human nature might just be parables about American consumerism.
What we do know is robust enough to act upon. The data—from Brickman’s lottery winners to Lykken’s twins to Bergler’s materialism studies—converges on a conclusion that feels like common sense once you strip away the advertising: your brain didn’t evolve to be satisfied by accumulation. It evolved to want, to anticipate, to strive. Lasting satisfaction comes not from fulfilling those wants, but from changing the relationship you have with wanting itself. It requires buying less, comparing less, and occasionally stepping off the treadmill entirely to notice that the ground beneath your feet was never moving at all.
