The tragedy of human cognition

Robin Marantz Henig writes on religion, citing Scott Atran, anthropologist at the National Center for Scientific Research in Paris, with joint appointments at the University of Michigan and the John Jay College of Criminal Justice in New York:

he presents students with a wooden box that he pretends is an African relic. “If you have negative sentiments toward religion,” he tells them, “the box will destroy whatever you put inside it.” Many of his students say they doubt the existence of God, but in this demonstration they act as if they believe in something. Put your pencil into the magic box, he tells them, and the nonbelievers do so blithely. Put in your driver’s license, he says, and most do, but only after significant hesitation. And when he tells them to put in their hands, few will.

If they don’t believe in God, what exactly are they afraid of?

...

[Scientists studying the evolution of religion] tend to agree on one point: that religious belief is an outgrowth of brain architecture that evolved during early human history. What they disagree about is why a tendency to believe evolved, whether it was because belief itself was adaptive or because it was just an evolutionary byproduct, a mere consequence of some other adaptation in the evolution of the human brain.
...

Angels, demons, spirits, wizards, gods and witches have peppered folk religions since mankind first started telling stories. Charles Darwin noted this in “The Descent of Man.” “A belief in all-pervading spiritual agencies,” he wrote, “seems to be universal.” According to anthropologists, religions that share certain supernatural features — belief in a noncorporeal God or gods, belief in the afterlife, belief in the ability of prayer or ritual to change the course of human events — are found in virtually every culture on earth.

...

When a trait is universal, evolutionary biologists look for a genetic explanation and wonder how that gene or genes might enhance survival or reproductive success. In many ways, it’s an exercise in post-hoc hypothesizing: what would have been the advantage, when the human species first evolved, for an individual who happened to have a mutation that led to, say, a smaller jaw, a bigger forehead, a better thumb? How about certain behavioral traits, like a tendency for risk-taking or for kindness?

Atran saw such questions as a puzzle when applied to religion. So many aspects of religious belief involve misattribution and misunderstanding of the real world. Wouldn’t this be a liability in the survival-of-the-fittest competition? To Atran, religious belief requires taking “what is materially false to be true” and “what is materially true to be false.” One example of this is the belief that even after someone dies and the body demonstrably disintegrates, that person will still exist, will still be able to laugh and cry, to feel pain and joy. This confusion “does not appear to be a reasonable evolutionary strategy,” Atran wrote in “In Gods We Trust: The Evolutionary Landscape of Religion” in 2002. “Imagine another animal that took injury for health or big for small or fast for slow or dead for alive. It’s unlikely that such a species could survive.” He began to look for a sideways explanation: if religious belief was not adaptive, perhaps it was associated with something else that was.

...

Some cognitive scientists think of brain functioning in terms of modules, a series of interconnected machines, each one responsible for a particular mental trick. They do not tend to talk about a God module per se; they usually consider belief in God a consequence of other mental modules.

Religion, in this view, is “a family of cognitive phenomena that involves the extraordinary use of everyday cognitive processes,” Atran wrote in “In Gods We Trust.” “Religions do not exist apart from the individual minds that constitute them and the environments that constrain them, any more than biological species and varieties exist independently of the individual organisms that compose them and the environments that conform them.”

...

Agent detection evolved because assuming the presence of an agent — which is jargon for any creature with volitional, independent behavior — is more adaptive than assuming its absence. If you are a caveman on the savannah, you are better off presuming that the motion you detect out of the corner of your eye is an agent and something to run from, even if you are wrong. If it turns out to have been just the rustling of leaves, you are still alive; if what you took to be leaves rustling was really a hyena about to pounce, you are dead.

A classic experiment from the 1940s by the psychologists Fritz Heider and Marianne Simmel suggested that imputing agency is so automatic that people may do it even for geometric shapes. For the experiment, subjects watched a film of triangles and circles moving around. When asked what they had been watching, the subjects used words like “chase” and “capture.” They did not just see the random movement of shapes on a screen; they saw pursuit, planning, escape.

So if there is motion just out of our line of sight, we presume it is caused by an agent, an animal or person with the ability to move independently. This usually operates in one direction only; lots of people mistake a rock for a bear, but almost no one mistakes a bear for a rock.

What does this mean for belief in the supernatural? It means our brains are primed for it, ready to presume the presence of agents even when such presence confounds logic. “The most central concepts in religions are related to agents,” Justin Barrett, a psychologist, wrote in his 2004 summary of the byproduct theory, “Why Would Anyone Believe in God?” Religious agents are often supernatural, he wrote, “people with superpowers, statues that can answer requests or disembodied minds that can act on us and the world.”

A second mental module that primes us for religion is causal reasoning. The human brain has evolved the capacity to impose a narrative, complete with chronology and cause-and-effect logic, on whatever it encounters, no matter how apparently random. “We automatically, and often unconsciously, look for an explanation of why things happen to us,” Barrett wrote, “and ‘stuff just happens’ is no explanation. Gods, by virtue of their strange physical properties and their mysterious superpowers, make fine candidates for causes of many of these unusual events.”

...

A third cognitive trick is a kind of social intuition known as theory of mind. It’s an odd phrase for something so automatic, since the word “theory” suggests formality and self-consciousness. Other terms have been used for the same concept, like intentional stance and social cognition. One good alternative is the term Atran uses: folkpsychology.

Folkpsychology, as Atran and his colleagues see it, is essential to getting along in the contemporary world, just as it has been since prehistoric times. It allows us to anticipate the actions of others and to lead others to believe what we want them to believe; it is at the heart of everything from marriage to office politics to poker. People without this trait, like those with severe autism, are impaired, unable to imagine themselves in other people’s heads.

The process begins with positing the existence of minds, our own and others’, that we cannot see or feel. This leaves us open, almost instinctively, to belief in the separation of the body (the visible) and the mind (the invisible). If you can posit minds in other people that you cannot verify empirically, suggests Paul Bloom, a psychologist and the author of “Descartes’ Baby,” published in 2004, it is a short step to positing minds that do not have to be anchored to a body. And from there, he said, it is another short step to positing an immaterial soul and a transcendent God.

...

The adaptive advantage of folkpsychology is obvious. According to Atran, our ancestors needed it to survive their harsh environment, since folkpsychology allowed them to “rapidly and economically” distinguish good guys from bad guys. But how did folkpsychology — an understanding of ordinary people’s ordinary minds — allow for a belief in supernatural, omniscient minds? And if the byproduct theorists are right and these beliefs were of little use in finding food or leaving more offspring, why did they persist?

...

The bottom line, according to byproduct theorists, is that children are born with a tendency to believe in omniscience, invisible minds, immaterial souls — and then they grow up in cultures that fill their minds, hard-wired for belief, with specifics. It is a little like language acquisition, Paul Bloom says, with the essential difference that language is a biological adaptation and religion, in his view, is not. We are born with an innate facility for language but the specific language we learn depends on the environment in which we are raised. In much the same way, he says, we are born with an innate tendency for belief, but the specifics of what we grow up believing — whether there is one God or many, whether the soul goes to heaven or occupies another animal after death — are culturally shaped.

Whatever the specifics, certain beliefs can be found in all religions. Those that prevail, according to the byproduct theorists, are those that fit most comfortably with our mental architecture. Psychologists have shown, for instance, that people attend to, and remember, things that are unfamiliar and strange, but not so strange as to be impossible to assimilate. Ideas about God or other supernatural agents tend to fit these criteria. They are what Pascal Boyer, an anthropologist and psychologist, called “minimally counterintuitive”: weird enough to get your attention and lodge in your memory but not so weird that you reject them altogether. A tree that talks is minimally counterintuitive, and you might believe it as a supernatural agent. A tree that talks and flies and time-travels is maximally counterintuitive, and you are more likely to reject it.

It is not enough for an agent to be minimally counterintuitive for it to earn a spot in people’s belief systems. An emotional component is often needed, too, if belief is to take hold. “If your emotions are involved, then that’s the time when you’re most likely to believe whatever the religion tells you to believe,” Atran says. Religions stir up emotions through their rituals — swaying, singing, bowing in unison during group prayer, sometimes working people up to a state of physical arousal that can border on frenzy. And religions gain strength during the natural heightening of emotions that occurs in times of personal crisis, when the faithful often turn to shamans or priests. The most intense personal crisis, for which religion can offer powerfully comforting answers, is when someone comes face to face with mortality.

...

Fear of death is an undercurrent of belief. The spirits of dead ancestors, ghosts, immortal deities, heaven and hell, the everlasting soul: the notion of spiritual existence after death is at the heart of almost every religion. According to some adaptationists, this is part of religion’s role, to help humans deal with the grim certainty of death. Believing in God and the afterlife, they say, is how we make sense of the brevity of our time on earth, how we give meaning to this brutish and short existence. Religion can offer solace to the bereaved and comfort to the frightened.

...

Whether or not it is adaptive, belief in the afterlife gains power in two ways: from the intensity with which people wish it to be true and from the confirmation it seems to get from the real world. This brings us back to folkpsychology. We try to make sense of other people partly by imagining what it is like to be them, an adaptive trait that allowed our ancestors to outwit potential enemies. But when we think about being dead, we run into a cognitive wall. How can we possibly think about not thinking?

...

The trick in thinking about adaptation is that even if a trait offers no survival advantage today, it might have had one long ago. This is how Darwinians explain how certain physical characteristics persist even if they do not currently seem adaptive — by asking whether they might have helped our distant ancestors form social groups, feed themselves, find suitable mates or keep from getting killed. A facility for storing calories as fat, for instance, which is a detriment in today’s food-rich society, probably helped our ancestors survive cyclical famines.

So trying to explain the adaptiveness of religion means looking for how it might have helped early humans survive and reproduce. As some adaptationists see it, this could have worked on two levels, individual and group. Religion made people feel better, less tormented by thoughts about death, more focused on the future, more willing to take care of themselves. As William James put it, religion filled people with “a new zest which adds itself like a gift to life . . . an assurance of safety and a temper of peace and, in relation to others, a preponderance of loving affections.”

Such sentiments, some adaptationists say, made the faithful better at finding and storing food, for instance, and helped them attract better mates because of their reputations for morality, obedience and sober living. The advantage might have worked at the group level too, with religious groups outlasting others because they were more cohesive, more likely to contain individuals willing to make sacrifices for the group and more adept at sharing resources and preparing for warfare.

...“Religious and secular rituals can both promote cooperation,” [Richard Sosis, an anthropologist with positions at the University of Connecticut and Hebrew University of Jerusalem] wrote in American Scientist in 2004. But religious rituals “generate greater belief and commitment” because they depend on belief rather than on proof. The rituals are “beyond the possibility of examination,” he wrote, and a commitment to them is therefore emotional rather than logical — a commitment that is, in Sosis’s view, deeper and more long-lasting.

Rituals are a way of signaling a sincere commitment to the religion’s core beliefs, thereby earning loyalty from others in the group. “By donning several layers of clothing and standing out in the midday sun,” Sosis wrote, “ultraorthodox Jewish men are signaling to others: ‘Hey! Look, I’m a haredi’ — or extremely pious — ‘Jew. If you are also a member of this group, you can trust me because why else would I be dressed like this?’ ” These “signaling” rituals can grant the individual a sense of belonging and grant the group some freedom from constant and costly monitoring to ensure that their members are loyal and committed. The rituals are harsh enough to weed out the infidels, and both the group and the individual believers benefit.

...

What can be made of atheists, then? If the evolutionary view of religion is true, they have to work hard at being atheists, to resist slipping into intrinsic habits of mind that make it easier to believe than not to believe. Atran says he faces an emotional and intellectual struggle to live without God in a nonatheist world, and he suspects that is where his little superstitions come from, his passing thought about crossing his fingers during turbulence or knocking on wood just in case. It is like an atavistic theism erupting when his guard is down. The comforts and consolations of belief are alluring even to him, he says, and probably will become more so as he gets closer to the end of his life. He fights it because he is a scientist and holds the values of rationalism higher than the values of spiritualism.

This internal push and pull between the spiritual and the rational reflects what used to be called the “God of the gaps” view of religion. The presumption was that as science was able to answer more questions about the natural world, God would be invoked to answer fewer, and religion would eventually recede. Research about the evolution of religion suggests otherwise. No matter how much science can explain, it seems, the real gap that God fills is an emptiness that our big-brained mental architecture interprets as a yearning for the supernatural. The drive to satisfy that yearning, according to both adaptationists and byproduct theorists, might be an inevitable and eternal part of what Atran calls the tragedy of human cognition.
