"If you're going to ask the rise-of-the-West question," said Henrich, an author of the paper, "there's this big unmentioned thing called psychology that's got to be part of the story."

"There's good evidence that Europe's kinship structure was not much different from the rest of the world," said Jonathan Schulz, an assistant professor of economics at George Mason University and another author of the paper. But then, from the Middle Ages to 1500 A.D., the Western Church (later known as the Roman Catholic Church) started banning marriages to cousins, step-relatives, in-laws, and even spiritual-kin, better known as godparents.

"Meanwhile in Iran, in Persia, Zoroastrianism was not only promoting cousin marriage but promoting marriage between siblings," Henrich said. Although Islam outlawed polygyny extending beyond four wives, and the Eastern Orthodox Church adopted policies against incest, no institution came close to the strict, widespread policies of the Western Church.

Those policies first altered family structures and then the psychologies of members. Henrich and his colleagues think that individuals adapt cognition, emotions, perceptions, thinking styles, and motivations to fit their social networks. Kin-based institutions reward conformity, tradition, nepotism, and obedience to authority, traits that help protect assets—such as farms—from outsiders. But once familial barriers crumble, the team predicted that individualistic traits like independence, creativity, cooperation, and fairness with strangers would increase.


Using 24 psychological variables collected in surveys, experiments, and observations, they measured the global prevalence of traits that correspond or conflict with individualism. To test for willingness to help strangers, for example, they collected data on blood-donation rates across Italy, finding a correlation between high donation rates and low cousin-marriage rates. With their kinship intensity index, Schutz said, they can also predict which diplomats in New York City will or will not pay parking tickets: Those from countries with higher rates of cousin marriages are more likely to get a ticket and less likely to pay one
