Rice Farming and Collectivism: Three Studies, One Critique

Does the Way We Farm Shape How We Relate to Each Other?

I was skeptical when I first came across the “rice theory” of culture. The idea that what grain your ancestors grew connects to how you think today sounded far too simple.

What this theory focuses on isn’t the nutritional content of the grain but the cooperation farming it required. The experience of managing water and labor together with neighbors may have shaped a culture that places high value on relationships between people. As I read the studies examining this, my thinking gradually shifted.

Cultural explanations are compelling, but they’re also easy to overstate. You can’t determine someone’s personality just because they grew up in a rice-farming region. Let’s start by looking at which groups these studies compared and what they actually measured.

2014: Comparing Regions Within China

In 2014, a research team led by Thomas Talhelm ran psychological tasks on 1,162 Han Chinese college students across six sites in China. Students from the rice-farming south showed a stronger tendency toward relational thinking and interdependence than students from the wheat-farming north. The difference held up even when comparing neighboring counties that sat right on the rice-wheat border. Talhelm’s talk at the University of Pennsylvania

The study’s starting point is the difference in cooperation required by traditional paddy farming versus dry-field farming. Paddy rice demands a large labor force, and farms sharing the same irrigation channels have to coordinate when to draw water. The researchers proposed that this interdependence may have produced a more relationship-centered culture than wheat farming did. University of Virginia’s research announcement

That’s not to say wheat farming requires no cooperation or irrigation whatsoever. How any crop is grown varies by climate and region. What this theory really asks us to look at isn’t the simple binary of “rice means cooperation, wheat means independence,” but rather how much work had to be handled collectively.

Comparing regions within a single country lets you hold some conditions constant in a way cross-country comparisons can’t. Still, the regions where these students grew up could differ in many ways beyond agriculture. This result alone can’t establish rice farming as the sole cause of the difference.

2018: Observing Behavior in Cafes

A follow-up study looked beyond surveys and psychological tasks to see whether the difference showed up in everyday life. The research team observed 8,964 people in cafes across six Chinese cities, noting whether each person sat alone or with others. Patrons in southern cities were less likely to sit alone.

In a separate observation, chairs were placed close to a walkway so that passing by became inconvenient. In the north, people were relatively more likely to move the chair out of the way; in the south, people were more likely to squeeze past instead. The researchers read this as a difference between changing one’s surroundings and adapting oneself to them. University of Chicago Booth School of Business, 2018 release

What I found interesting is that the difference showed up even in cities. It suggests that even people who never farm can be shaped by the way of life and relationships prevalent where they live.

Still, observing a cafe patron’s behavior doesn’t confirm anything about that particular person’s ancestral farming history. Sitting alone or moving a chair could just as easily be a matter of the day’s circumstances. The study compares regional tendencies across many people; it doesn’t create a test that identifies an individual as “individualist” based on one single action.

2024: Comparing Two Nearby State Farms

A 2024 paper in Nature Communications looks at two state-run farms in China’s Ningxia region. The two sites sit about 56km apart and share a similar climate, but differing terrain and soil conditions meant one grew paddy rice while the other mainly grew dry-field crops like wheat. The researchers leveraged the fact that government worker assignments to these farms were closer to arbitrary than to voluntary crop choices reflecting individual disposition.

The survey was conducted in 2017 with 234 farmers. Participants from the rice farm tended to describe themselves in relatively modest terms, favor friends over strangers more strongly, and think in more relational terms. The researchers interpreted this as evidence that the influence of farming style can emerge within a single generation.

That said, this wasn’t an experiment in which researchers randomly assigned people to farms. About three-quarters of participants were descendants who had grown up on the farms, and participants at both sites weren’t randomly sampled either. The researchers statistically adjusted for demographic differences like age and education. It’s also worth noting that the significance of differences in the cognitive-style tasks shifted depending on whether those adjustments were applied. Talhelm & Dong, 2024 paper

This study made me take the relationship between farming style and culture more seriously. It tried to re-examine questions that arise when comparing broad regions by narrowing the focus to two farms with similar environments. It’s not proof that rules out every other cause, but the approach — as a complement to the earlier studies — struck me as impressive.

What Gets Lost When You Divide the World Into Just Rice and Wheat

In 2015, Hu and Yuan criticized the crop classification used in the earlier research. Some regions grouped as “wheat-farming north” were in fact places where corn mattered a great deal. Their point: to match what the analysis actually measured, it would be more accurate to describe the comparison as “rice versus non-rice crops” rather than “rice versus wheat.”

The two researchers argued that rather than fixating on crop names, one should examine labor intensity and the need for cooperation by region directly, since even the same crop can demand a different way of working depending on growing conditions. Critical commentary in Frontiers in Psychology

Reading this critique alongside the original studies makes you think harder about how far to extend their conclusions. It’s a stretch to take differences observed within China and scale them up directly into a difference between “East and West” as a whole. There are many conditions worth examining alongside farming — economics, institutions, education, migration history. And the fact that one study found the modernization hypothesis had weak explanatory power doesn’t mean economic development has zero effect on culture.

Oswarld’s Lens

I found the explanation too simple at first, but I became interested in how these studies kept confirming the same question through different methods. College psychology tasks, cafe behavior, and comparisons between neighboring farms each have their own strengths and limits. Rather than leaning on any single method, there’s good reason to look at what multiple approaches show us together.

It also struck me that I stopped equating collectivism with kindness toward everyone. Valuing close relationships also implies the possibility of treating people outside that circle differently. This brought to mind “jeong,” the deep-seated communal bond in Korean society. A network in which familiar people look out for each other feels solid and reassuring, but a newcomer can just as easily feel left out. I don’t mean to suggest that Korean jeong can be explained by rice farming alone.

In my own experience building go-to-market strategies, culture has always been an important consideration. When you’re trying to understand why the same product succeeds in one market and underperforms in another, looking at translation or ad copy alone isn’t enough. You also need to see who the user makes decisions with, and through what relationships the product gets introduced and used.

I think this research helps make such questions more concrete. I’m not suggesting we use it to pre-label customers in a given region as “collectivists.” Rather, the point is to go and directly examine how cooperation and trust actually form in that market.

In Korea too, single-person households are growing and the way people work is changing. I’m curious about where the long-standing patterns of relationship persist, and what shifts under new conditions. To me, research showing that past agriculture shaped culture isn’t an argument that change is impossible — it’s an invitation to ask how culture itself might shift as living conditions change.
