Eyeing Religion
Were our ancestors hardwired by evolution to believe in God? That is the subject of an article entitled "Sight Unseen: Are we wired to serve God?" by Jeffrey Weiss in The Dallas Morning News that can be found here.
Refreshments are sold on the honor system in the break room at the University of Newcastle – people who get a cup of coffee or tea are supposed to leave money. Researchers found that when they added a picture of eyes above the payment box, more than twice as much money was deposited, compared with weeks when the eyes were replaced by a picture of flowers.
People were subconsciously triggered into acting more honestly, as if they were actually being watched, even though they knew the eyeballs were mere paper and ink.
In general, people are nicer than they need to be, experiments show. That's not to say some individuals aren't liars or cheats. But many of us show a bit of Good Samaritan, even when we don't know whom we're helping and seem to gain no benefit.
But that seems to contradict evolution theory, because successful individual cheaters should gain a Darwinian advantage. A prehistoric thief who swiped the equivalent of a cup of coffee would have been better off than the honest fellow who "paid" for it. And the thief, by gaining an advantage that improved his odds of survival, would have been more likely to pass on those "selfish" genes.
Early humans who were attentive [to faces and acted more honestly when they thought they were watched] were less likely to get caught and punished for doing something wrong. That made them more likely to pass their genes along, said Dr. Wilson, whose book Darwin's Cathedral uses evolution to explain religion.
As Homo sapiens developed language and imagination, that gave our quick-triggered brain many more possibilities. If physical explanations weren't good enough, our ancestors' brains automatically, irresistibly came up with other alternatives: A sin explained leprosy. A virgin sacrifice kept the volcano quiet. A prayer brought the rain.
In other words, our ancestors' brains may have been biologically inclined to believe in the supernatural.
What if a particular tribe had those tendencies so strongly that it developed a religion that told its believers that a power was always watching? Would the very notion of an unseen, powerful watcher prompt more cooperative, generous behavior in people who weren't actually being watched? ...
Call it the Santa Claus Effect: "He knows when you've been bad or good, so be good for goodness sake." ...Would believers in a Supernatural Enforcer have a leg up on other early humans? If so, their culture and their religion would have been more likely to survive.
A few last-minute caveats: Every link in this chain is controversial. Behaviorists, psychologists and biologists have alternate theories about why humans cooperate and practice religion. Even those who agree on the broad outlines disagree about important details.
And even the most fervent proponents say this all adds up to a Darwinian nudge toward niceness, not a shove.
But the coffee room effect, now . . . that is interesting. Do you suppose we could sneak into the Discovery institute some night and plaster the walls with pictures of ol' Honest Abe's eyes?
