Historical Dynamics and Cultural Associations of Relational Norms in American and Chinese Political Discourse
Using computational text analysis on historical U.S. and Chinese political discourse, this study reveals that while broad cultural shifts in individualism-collectivism and tightness-looseness influence cooperative relational norms, the temporal dynamics and specific relationships affected by these cultural changes differ significantly between the two nations.

Human beings are social creatures who navigate the world through a complex web of relationships. We do not treat a stranger the same way we treat a sibling, nor do we interact with a boss as we would with a romantic partner. These differences are not random; they are governed by unwritten rules, or norms, that tell us what to expect and how to behave in specific situations. A parent is expected to provide care without asking for anything in return, while a business transaction relies on a clear exchange of value. These expectations are deeply rooted in our culture, which shapes how we view authority, independence, and our obligations to one another. But cultures are not static; they shift over time as societies grow, economies change, and values evolve. The question that has long intrigued researchers is whether these broad cultural shifts happen everywhere at once, or if they ripple through our lives differently depending on the specific relationship we are in. Does a change in how a society values individual freedom, for instance, change the way we treat our children in the same way it changes the way we treat our employees?
To answer this, a team of researchers turned to the written records of history, treating language as a window into the collective mind of a nation. They focused on two distinct societies, the United States and China, examining millions of words spoken and written over more than a century. They looked specifically at four fundamental ways humans cooperate: care, which involves giving support based on need; hierarchy, which involves coordinating actions between people of unequal authority; transaction, which involves balancing benefits through exchange; and mating, which involves forming sexual partnerships. By analyzing political speeches from the U.S. Congress and articles from China's official newspaper, the People's Daily, the team could trace how often these themes appeared in public discourse from 1879 to 2022 in America and from 1946 to 2021 in China. They then compared these trends against measures of broader cultural values, such as how much a society emphasizes individual independence versus group interdependence, and how strictly it enforces social rules.
The researchers found that the story of cultural change is not a single, uniform narrative that plays out the same way in every corner of life. Instead, the connection between broad cultural values and specific relationship norms depends heavily on the context. In the United States, the data suggested that shifts in cultural values, such as a move toward greater individualism or a loosening of social rules, tended to precede changes in how people talked about public relationships. For example, as American culture became more individualistic, the language used to describe the relationship between bosses and employees began to shift, showing more emphasis on care. Similarly, changes in how teachers and students were discussed followed broader cultural trends. However, these connections were less clear when looking at private or family relationships, suggesting that in the U.S., broad cultural shifts are most visible in the expectations surrounding formal, public roles.
In contrast, the patterns observed in China were more widespread and bidirectional. Here, changes in cultural values and changes in relationship norms influenced each other across a much broader range of relationships, including those between parents and children, teachers and students, and even close friends. The researchers found that when the cultural value of collectivism—prioritizing the group over the individual—was high, it was followed by a decrease in language emphasizing hierarchy in parent-child and teacher-student relationships. This suggests that as a society places more weight on collective goals, the rigid structures of authority within these formative relationships may soften. Conversely, when people talked more about the exchange of benefits between friends or coworkers, it predicted a subsequent rise in collectivist values. This indicates that in China, the way people talk about their daily interactions and reciprocal obligations helps shape the broader cultural landscape, not just the other way around.
One of the most striking findings was that these cultural shifts did not affect all types of cooperation equally. For instance, in both countries, the amount of language discussing mating increased over time, but the drivers of this change were different. In the U.S., the rise in mating-related discourse seemed to precede changes in how strict or loose the society felt about social rules. In China, however, the relationship was more complex, with cultural values sometimes predicting changes in mating discourse and vice versa. The researchers also noted that the timing of these shifts often aligned with major historical events. In the U.S., spikes in language about transactions coincided with economic downturns, such as the Great Depression and the 2008 financial crisis. In China, fluctuations in language about hierarchy tracked closely with turbulent political periods, including the Cultural Revolution.
The study challenges the idea that cultural change is a monolithic force that sweeps across a society, altering every relationship in the same way. Instead, it suggests that cultural evolution is a patchwork process. In the United States, broad cultural values seem to filter down most strongly into the expectations of public, professional life. In China, these values appear to be woven more deeply into the fabric of personal and familial bonds, with a constant feedback loop between what people believe about their society and how they treat one another in specific relationships. By looking at the specific norms that govern different types of connections, the researchers were able to see a more nuanced picture of history. They showed that to understand how a culture changes, one must look not just at the big picture of national values, but at the small, specific rules that guide how a boss speaks to an employee, a parent to a child, or a friend to a friend. These relational norms act as the specific channels through which the broad currents of cultural change flow, sometimes speeding up, sometimes slowing down, and sometimes changing direction entirely depending on the relationship in question.
