New research unlocks the genius of George W. Bush:
In two studies led by Assistant Psychology Professor Michael Inzlicht, participants performed a Stroop task a well-known test of cognitive control while hooked up to electrodes that measured their brain activity.
Compared to non-believers, the religious participants showed significantly less activity in the anterior cingulate cortex (ACC), a portion of the brain that helps modify behavior by signaling when attention and control are needed, usually as a result of some anxiety-producing event like making a mistake.
The stronger their religious zeal and the more they believed in God, the less their ACC fired in response to their own errors, and the fewer errors they made. "You could think of this part of the brain like a cortical alarm bell that rings when an individual has just made a mistake or experiences uncertainty," says lead author Inzlicht, who teaches and conducts research at the University of Toronto Scarborough. "We found that religious people or even people who simply believe in the existence of God show significantly less brain activity in relation to their own errors. They're much less anxious and feel less stressed when they have made an error."
