Did the Winter Olympic Controversies Reveal How Cultures Think Differently About Fairness?

The 2022 Winter Olympics will likely be remembered as much for their controversies as for the athletic performances. There were disputes about the fairness of the judges, the use of performance-enhancing drugs, and the appropriate age at which athletes should be allowed to enter such a physical and emotional trial. The Olympics are supposed to bring the world together, but in times of global tensions, they often prove to be just a reflection of nationalistic undercurrents. These Olympics may also have revealed something else: how cultures shape our emotions—particularly those surrounding notions of fairness.

When you first heard or read about an athlete doping or a judge bumping up the scores of his countrymen, you likely had an immediate gut reaction. What seems fair feels instinctual—we don’t even have to think about it. For that reason, it has long been assumed by psychology researchers that our fairness intuition was universal, something shared by all humans. However, recent cross-cultural studies have revealed that there are vast differences across the globe. Culture, it turns out, shapes our beliefs and actions in surprising ways.

What Feels Fair Isn’t Universal

In the summer of 1995, a young graduate student in anthropology at UCLA named Joe Henrich traveled to Peru to carry out some fieldwork among the Machiguenga, an indigenous people who live north of Machu Picchu in the Amazon basin. The Machiguenga had traditionally been horticulturalists who lived in single-family, thatch-roofed houses in small hamlets composed of clusters of extended families. For sustenance, they relied on local game and produce from small-scale farming. They shared with their kin but rarely traded with outside groups.

While the setting was fairly typical for an anthropologist, Henrich’s research was not. Rather than practice traditional ethnography, he decided to run a behavioral experiment that had been developed by economists. Henrich used a “game”—along the lines of the famous prisoner’s dilemma—to see whether isolated cultures shared with the West the same basic instinct for fairness. In doing so, Henrich expected to test one of the foundational assumptions underlying such experiments, and indeed underpinning the entire fields of economics and psychology: that humans all share the same cognitive machinery—the same evolved rational and psychological hardwiring.

The test that Henrich introduced to the Machiguenga was called the ultimatum game. The rules are simple: in each game there are two players who remain anonymous to each other. The first player is given an amount of money, say $100, and told that he has to offer some of the cash, in an amount of his choosing, to the other subject. The second player can accept or refuse the split. But there’s a hitch: players know that if the recipient refuses the offer, both leave empty-handed. North Americans, who are the most common subjects for such experiments, usually offer a 50-50 split when on the giving end. When on the receiving end, they show an eagerness to punish the other player for uneven splits at their own expense. In short, Americans show the tendency to be equitable with strangers—and to punish those who are not.

Among the Machiguenga, word quickly spread of the young, square-jawed visitor from America giving away money. The stakes Henrich used in the game with the Machiguenga were not insubstantial—roughly equivalent to the few days’ wages they sometimes earned from episodic work with logging or oil companies. So Henrich had no problem finding volunteers. What he had great difficulty with, however, was explaining the rules, as the game struck the Machiguenga as deeply odd.

When he began to run the game it became immediately clear that Machiguengan behavior was dramatically different from that of the average North American. To begin with, the offers from the first player were much lower. In addition, when on the receiving end of the game, the Machiguenga rarely refused even the lowest possible amount. “It just seemed ridiculous to the Machiguenga that you would reject an offer of free money,” says Henrich.

They just didn’t understand why anyone would sacrifice money to punish someone who had the good luck of getting to play the other role in the game.

The potential implications of the unexpected results were quickly apparent to Henrich. He knew that a vast amount of scholarly literature in the social sciences—particularly in economics and psychology—relied on the ultimatum game and similar experiments. At the heart of most of that research was the implicit assumption that the results revealed evolved psychological traits common to all humans, never mind that the test subjects were nearly always from the industrialized West. Henrich realized that if the Machiguenga results stood up, and if similar differences could be measured across other populations, this assumption of universality would have to be challenged.

Henrich had thought he would be adding a small branch to an established tree of knowledge. It turned out he was sawing at the very trunk. He began to wonder: What other certainties about “human nature” in social science research would need to be reconsidered when tested across diverse populations?

Henrich soon landed a grant from the MacArthur Foundation to take his fairness games on the road. With the help of a dozen other colleagues he led a study of 14 other small-scale societies, in locales from Tanzania to Indonesia. Differences abounded in the behavior of both players in the ultimatum game. In no society did he find people who were purely selfish (that is, who always offered the lowest amount, and never refused a split), but average offers from place to place varied widely. In some societies—ones where gift-giving is heavily used to curry favor or gain allegiance—the first player would often make seemingly overly generous offers in excess of 60 percent, and yet the second player would often reject them, behaviors almost never observed among Americans.

The research established Henrich as an up-and-coming scholar. In 2004, he was given the US Presidential Early Career Award for young scientists at the White House. But his work also made him a controversial figure. When he presented his research to the anthropology department at the University of British Columbia during a job interview a year later, he recalls a hostile reception. Anthropology is the social science most interested in cultural differences, but the young scholar’s methods of using games and statistics to test and compare cultures with the West seemed heavy-handed and invasive to some.

So instead of toeing the line, he switched teams. A few well-placed people outside the anthropology department at the University of British Columbia saw great promise in Henrich’s work and created a position for him, split between the economics department and the psychology department. It was in the psychology department that he found two kindred spirits in Steven Heine and Ara Norenzayan. Together the three set about writing a paper that they hoped would fundamentally challenge the way social scientists thought about human behavior, cognition and culture.

How Culture Leads Life’s Dance

A modern liberal arts education gives lots of lip service to the idea of cultural diversity. It’s generally agreed that all of us see the world in ways that are sometimes socially and culturally constructed, that pluralism is good, and that ethnocentrism is bad. But beyond that the ideas get muddy. That we should welcome and celebrate people of all backgrounds seems obvious, but the implied corollary—that people from different ethno-cultural origins have particular attributes that add spice to the body politic—becomes more problematic. To avoid stereotyping, it is rarely stated bluntly just exactly what those culturally derived qualities might be. Challenge liberal arts graduates on their appreciation of cultural diversity and you’ll often find them retreating to the anodyne notion that under the skin everyone is really alike.

If you take a broad look at the social science curriculum of the last few decades, it becomes a little more clear why modern graduates are so unmoored. The last generation or two of undergraduates have largely been taught by a cohort of social scientists busily doing penance for the racism and Eurocentrism of their predecessors, albeit in different ways. Many anthropologists took to the navel gazing of postmodernism and swore off attempts at rationality and science, which were disparaged as weapons of cultural imperialism.

Economists and psychologists, for their part, did an end run around the issue with the convenient assumption that their job was to study the human mind stripped of culture. The human brain is genetically comparable around the globe, it was agreed, so human hardwiring for much behavior, perception and cognition should be similarly universal. No need, in that case, to look beyond the convenient population of undergraduates for test subjects. A 2008 survey of the top six psychology journals dramatically shows how common that assumption was: more than 96 percent of the subjects tested in psychological studies from 2003 to 2007 were Westerners—with nearly 70 percent from the United States alone. Put another way: 96 percent of human subjects in these studies came from countries that represent only 12 percent of the world’s population.

Henrich’s work with the ultimatum game was an example of a small but growing countertrend in the social sciences, one in which researchers look straight at the question of how deeply culture shapes human cognition. His new colleagues in the psychology department, Heine and Norenzayan, were also part of this trend. Heine focused on the different ways people in Western and Eastern cultures perceived the world, reasoned, and understood themselves in relation to others. Norenzayan’s research focused on the ways religious belief influenced bonding and behavior. The three began to compile examples of cross-cultural research that, like Henrich’s work with the Machiguenga, challenged long-held assumptions of human psychological universality.

Some of that research went back a generation. It was in the 1960s, for instance, that researchers discovered that aspects of visual perception were different from place to place. One of the classics of the literature, the Müller-Lyer illusion, showed that where you grew up would determine to what degree you would fall prey to the illusion that these two lines are different in length:

Researchers found that Americans perceive the line with the ends feathered outward (top) as being longer than the line with the arrow tips (bottom). The hunter-gatherer San people of the Kalahari, on the other hand, were more likely to see the lines as they are: equal in length. Subjects from more than a dozen cultures were tested, and Americans were at the far end of the distribution—seeing the illusion more dramatically than all others.

As Heine, Norenzayan, and Henrich furthered their search, they began to find research suggesting wide cultural differences almost everywhere they looked: in spatial reasoning, the way we infer the motivations of others, categorization, moral reasoning, the boundaries between the self and others, and other arenas. These differences, they believed, were not genetic. The distinct ways Americans and Machiguengans played the ultimatum game, for instance, wasn’t because their brains had evolved differently. Rather, Americans, without fully realizing it, were manifesting a psychological tendency shared with people in other industrialized countries that had been refined and handed down through hundreds of generations in ever more complex market economies. When people are constantly doing business with strangers, it helps when they have the desire to go out of their way (with a lawsuit, a call to the Better Business Bureau, or a bad Yelp review) when they feel cheated. Because Machiguengan culture had a different history, their gut feeling about what was fair was distinctly their own. In the small-scale societies with a strong culture of gift-giving, yet another conception of fairness prevailed. There, generous financial offers were turned down because people’s minds had been shaped by a cultural norm that taught them that the acceptance of generous gifts brought burdensome obligations. Our economies hadn’t been shaped by our sense of fairness; it was the other way around.

American participants are exceptional even within the unusual population of Westerners—outliers among outliers

The growing body of cross-cultural research that the three researchers were compiling suggested that the mind’s capacity to adapt itself to cultural and environmental settings was far greater than had been assumed. The most interesting thing about cultures may not be in the observable things they do—the rituals, eating preferences, codes of behavior and the like—but in the way they mold our most fundamental conscious and unconscious thinking and perception.

As the three continued their work, they noticed something else that was remarkable: again and again one group of people appeared to be particularly unusual when compared to other populations—with perceptions, behaviors and motivations that were almost always sliding down one end of the human bell curve.

In the end they titled their paper “The Weirdest People in the World?” By “weird” they meant not just unusual but Western, Educated, Industrialized, Rich, and Democratic. It is not just our Western habits and cultural preferences that are different from the rest of the world, it appears. The very way we think about ourselves and others—and even the way we perceive reality—makes us distinct from other humans on the planet, not to mention from the vast majority of our ancestors. Among Westerners, the data showed that Americans were often the most unusual, leading the researchers to conclude that “American participants are exceptional even within the unusual population of Westerners—outliers among outliers.”

Given the data, they concluded that social scientists could not possibly have picked a worse population from which to draw broad generalizations. Researchers had been doing the equivalent of studying penguins while believing that they were learning insights applicable to all birds.

The turn that Henrich, Heine and Norenzayan are asking social scientists to make is not an easy one: accounting for the influence of culture on cognition will be a herculean task. Cultures are not monolithic; they can be endlessly parsed. Ethnic backgrounds, religious beliefs, economic status, parenting styles, rural upbringing versus urban or suburban—there are hundreds of cultural differences that individually and in endless combinations influence our conceptions of fairness, how we categorize things, our method of judging and decision making, and our deeply held beliefs about the nature of the self, among other aspects of our psychological makeup.

We are just at the beginning of learning how these fine-grained cultural differences affect our thinking. Recent research has shown that people in “tight” cultures, those with strong norms and low tolerance for deviant behavior (think India, Malaysia and Pakistan), develop higher impulse control and more self-monitoring abilities than those from other places. Men raised in the honor culture of the American South have been shown to experience much larger surges of testosterone after insults than do Northerners. Research published late last year suggested psychological differences at the city level too. Compared to San Franciscans, Bostonians’ internal sense of self-worth is more dependent on community status and financial and educational achievement. “A cultural difference doesn’t have to be big to be important,” Norenzayan said. “We’re not just talking about comparing New York yuppies to the Dani tribesmen of Papua New Guinea.”

At its heart, the challenge of the WEIRD paper is not simply to the field of experimental human research (do more cross-cultural studies!); it is a challenge to our Western conception of human nature. For some time now, the most widely accepted answer to the question of why humans, among all animals, have so successfully adapted to environments across the globe is that we have big brains with the ability to learn, improvise and problem-solve.

Henrich has challenged this “cognitive niche” hypothesis with the “cultural niche” hypothesis. He notes that the amount of knowledge in any culture is far greater than the capacity of individuals to learn or figure it all out on their own. He suggests that individuals tap that cultural storehouse of knowledge simply by mimicking (often unconsciously) the behavior and ways of thinking of those around them. We shape a tool in a certain manner, adhere to a food taboo, or think about fairness in a particular way, not because we individually have figured out that behavior’s adaptive value, but because we instinctively trust our culture to show us the way. When Henrich asked Fijian women why they avoided certain potentially toxic fish during pregnancy and breastfeeding, he found that many didn’t know or had fanciful reasons. Regardless of their personal understanding, by mimicking this culturally adaptive behavior they were protecting their offspring. The unique trick of human psychology, these researchers suggest, might be this: our big brains are evolved to let local culture lead us in life’s dance.

The applications of this new way of looking at the human mind are still in the offing. Henrich suggests that his research about fairness might first be applied to anyone working in international relations or development. People are not “plug and play,” as he puts it, and you cannot expect to drop a Western court system or form of government into another culture and expect it to work as it does back home. Those trying to use economic incentives to encourage sustainable land use will similarly need to understand local notions of fairness to have any chance of influencing behavior in predictable ways.

The universality of sports makes it an interesting case study of the effects of culture on the mind and on group behavior. It is not surprising that when athletes gather from around the world for an event like the Olympics, we may witness behavior that seems alien to us. The rules for a sport may be the same around the world, but the behavior of athletes will still be influenced by differing notions of fairness. Those from cultures where money is a proxy for status, for instance, may bend the rules for financial gain. Other athletes from countries with high levels of nationalism may tolerate bending the rules because they are motivated to win for their in-group at all costs. We won’t fully understand the behavior of athletes and teams until we understand how culture shapes their (and our) behavior.
