Ethnocentric Oxytocin

Despite the limitation on oxytocin’s social reach, its effect seems to be achieved more through inducing feelings of loyalty to the in-group than by fomenting hatred of the out-group. The Dutch researchers found some evidence that it enhances negative feelings, but this was not conclusive. “Oxytocin creates intergroup bias primarily because it motivates in-group favoritism and because it motivates out-group derogation,” they write.

Dr. De Dreu plans to investigate whether oxytocin mediates other social behaviors that evolutionary psychologists think evolved in early human groups. Besides loyalty to one’s own group, there would also have been survival advantages in rewarding cooperation and punishing deviants. Oxytocin, if it underlies these behaviors too, would perhaps have helped ancient populations set norms of behavior.

Early religions were also involved in establishing group cohesion and penalizing offenders. Could oxytocin be involved in the social aspects of the religious experience? Dr. De Dreu sees oxytocin’s effects as being very general, and no more likely to be associated with the religious experience than with soccer hooliganism. “When people get together with others who share their values, that drives up the level of oxytocin,” he said.

For military commanders, nothing is more important than the group cohesion of their soldiers, for which oxytocin might now seem the ideal prescription. But this assumption is a bridge too far, Dr. De Dreu said, given that his findings are based only on lab experiments.

What does it mean that a chemical basis for ethnocentrism is embedded in the human brain? “In the ancestral environment it was very important for people to detect in others whether they had a long-term commitment to the group,” Dr. De Dreu said. “Ethnocentrism is a very basic part of humans, and it’s not something we can change by education. That doesn’t mean that the negative aspects of it should be taken for granted.”
