Belief in the Brain

Sacred and secular ideas engage identical areas

Religious belief may seem to be a unique psychological experience, but a growing body of research shows that thinking about religion is no different from thinking about secular things— at least from the standpoint of the brain. In the first imaging study to compare religious and nonreligious thoughts, evaluating the truth of either type of statement was found to involve the same regions of the brain. Researchers at the University of California, Los Angeles, used functional MRI to evaluate brain activity in 15 devout Christians and 15 nonbelievers as the volunteers assessed the truth or falsity of a series of statements, some of which were religious (“angels exist”) and others nonreligious (“Alexander the Great was a very famous military ruler”). They found that when a subject believed a statement—whether it was religious or not—activity appeared in an area called the ventromedial prefrontal cortex, which is an area associated with emotions, rewards and self-representation. And although the nonbelievers rejected about half of the statements the believers accepted, the brain scans of both groups were indistinguishable, providing further proof that evaluating truth or falsity is independent of the content of the statement in question. “The fact that we found the same brain processing between believers and nonbelievers, despite the two groups’ completely different answers to the questions [about religion], is pretty surprising,” says Jonas Kaplan, a research psychologist at U.C.L.A. and co-author of the study. The finding adds to the mounting evidence against the notion, popular in the scientific community as well as among the general public, that religious faith is somehow different from other types of belief, explains co-author Sam Harris, also of U.C.L.A. In contrast to this assumption, he says, “Believing the sun is a star is rather the same as believing Jesus was born of a virgin.”

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
