"Eighty-five percent of the world has some sort of religious beliefs," says Michael Inzlicht, who cowrote the study with Alexa Tullett, both at the University of Toronto Scarborough. "I think it behooves us as psychologists to study why people have these beliefs; exploring what functions, if any, they may serve."
With two experiments, the researchers showed that when people think about religion and God, their brains respond differently—in a way that lets them take setbacks in stride and react with less distress to anxiety-provoking mistakes. Participants either wrote about religion or did a scrambled word task that included religion and God-related words. Then the researchers recorded their brain activity as they completed a computerized task—one that was chosen because it has a high rate of errors. The results showed that when people were primed to think about religion and God, either consciously or unconsciously, brain activity decreases in areas consistent with the anterior cingulate cortex (ACC), an area associated with a number of things, including regulating bodily states of arousal and serving an alerting function when things are going wrong, including when we make mistakes.
