Natural-born supernaturalists

Here is Michael Shermer's quick short summary of why people believe that supernatural elements control the world (I'm not too crazy about using the terms, patternicity and agenticity (related to theory of mind), but the underlying principles are summarized well here). So why we ascribe control of natural to supernatural entities:

The answer has two parts, starting with the concept of “patternicity,” which I defined in my December 2008 column as the human tendency to find meaningful patterns in meaningless noise. Consider the face on Mars, the Virgin Mary on a grilled cheese sandwich, satanic messages in rock music. Of course, some patterns are real. Finding predictive patterns in changing weather, fruiting trees, migrating prey animals and hungry predators was central to the survival of Paleolithic hominids.

The problem is that we did not evolve a baloney-detection device in our brains to discriminate between true and false patterns. So we make two types of errors: a type I error, or false positive, is believing a pattern is real when it is not; a type II error, or false negative, is not believing a pattern is real when it is. If you believe that the rustle in the grass is a dangerous predator when it is just the wind (a type I error), you are more likely to survive than if you believe that the rustle in the grass is just the wind when it is a dangerous predator (a type II error). Because the cost of making a type I error is less than the cost of making a type II error and because there is no time for careful deliberation between patternicities in the split-second world of predator-prey interactions, natural selection would have favored those animals most likely to assume that all patterns are real.

This on combination with our ability to infer agency is what makes a belief in the supernatural complete:

But we do something other animals do not do. As large-brained hominids with a developed cortex and a theory of mind—the capacity to be aware of such mental states as desires and intentions in both ourselves and others—we infer agency behind the patterns we observe in a practice I call “agent­icity”: the tendency to believe that the world is controlled by invisible intentional agents. We believe that these intentional agents control the world, sometimes invisibly from the top down (as opposed to bottom-up causal randomness). Together patternicity and agent­icity form the cognitive basis of shamanism, paganism, animism, polytheism, monotheism, and all modes of Old and New Age spiritualisms.

And then Shermer gives a plug for a new book, Supersense: Why we believe in the unbelievable by Bruce Hood. It has been getting fantastic reviews and its on my reading list for this summer:

There is now substantial evidence from cognitive neuroscience that humans readily find patterns and impart agency to them, well documented in the new book SuperSense (HarperOne, 2009) by University of Bristol psychologist Bruce Hood. Examples: children believe that the sun can think and follows them around; because of such beliefs, they often add smiley faces on sketched suns. Adults typically refuse to wear a mass murderer’s sweater, believing that “evil” is a supernatural force that imparts its negative agency to the wearer (and, alternatively, that donning Mr. Rogers’s cardigan will make you a better person). A third of transplant patients believe that the donor’s personality is transplanted with the organ. Genital-shaped foods (bananas, oysters) are often believed to enhance sexual potency. Subjects watching geometric shapes with eye spots interacting on a computer screen conclude that they represent agents with moral intentions.

“Many highly educated and intelligent individuals experience a powerful sense that there are patterns, forces, energies and entities operating in the world,” Hood explains. “More important, such experiences are not substantiated by a body of reliable evidence, which is why they are supernatural and unscientific. The inclination or sense that they may be real is our supersense.”

We are natural-born supernaturalists.
