In my first year of graduate school I worked in a condemned building. Sitting in my office was a woman I was trying to impress. We were talking about dance music. She liked club music and techno; I liked rap. I put on an acid jazz album in the compact disc player.
“How can you dance to this?” she asked.
“How can you not dance to this?” I replied, and then demonstrated the irresistibility of the track. For the most part, I only want to listen to music that makes me want to dance. Sorry, John Denver.
When I was young I was fascinated with psychic powers. I read every book in the libraries of both my elementary and high school on the subject, and was convinced that people had untapped mental abilities. All these books in the nonfiction section of my school’s library told me that people could move things with their minds, scry with crystal balls, and predict the future. We used only 10 percent of our brains, right? What else could that 90 percent possibly be for?
I was absolutely captivated by this idea and convinced of it, until I read Susan Blackmore’s sobering In Search of the Light: Adventures of a Parapsychologist in college.1 It was the first skeptical book I’d encountered and it scorched and salted the lush landscape of my paranormal beliefs. First Santa Claus and now this? Ideas can be beautiful and we don’t want to let go of them even when we know they’re wrong.
There are things in this world that deeply resonate with us. We seek them out. They hold our attention. They feel right. I want to dance to hip-hop. I feel moved by sad, uplifting stories. I want to believe that people can move things just by willing it to happen.
You are struck by a beautiful view from a mountain cabin. You hear that everyone gets the afterlife that they imagined they’d have, and the idea is so beautiful, and feels so right, that you smile in spite of yourself. You hear a story of some terrible thing that happened to a child that gives you chills and haunts you for days. You find yourself glued to the screen, watching a close basketball game. You hear a great joke and can’t wait to tell it to your friends.
With the huge variety of things we find compelling, it seems natural that a huge variety of qualities would make them compelling. There can’t be anything similar about what’s good about a pop song on the radio and what’s moving when someone recounts their near-death experience, can there?
Yes, there can. Strange as it might seem, compelling things share many similarities. My purpose in this book is to tie together research from many fields. I’ll do something that has never been done before and show how all these phenomena can be explained with the foundations of compellingness. I will show you that, like art and other sensory experiences, beliefs and explanations have aesthetic qualities that make us more or less likely to believe them. The same qualities appear again and again in riveting things, be they jokes, paintings, quotations, paranormal beliefs, religions, sports, video games, news, music, or gossip. The qualities that are common to all these things fit like a key in a lock with our psychological proclivities. I call it the compellingness foundations theory.
* * *
Understanding compellingness and how it works requires some understanding of our brains and how they were shaped by evolution. Our brains are a mix of old and newer processes that evolved at different times. They sometimes “disagree” on the meaning, importance, and value of things, and often we are clueless as to how we got our opinions. Often we are attracted to something or repelled by it and don’t know why, and the reasons we dredge up are confabulations, mere guesses about our underlying psychologies.
The old brain is evolutionarily older. It’s located near the top of the brain stem and the back of the head. We share much of its anatomy with other animals. It’s a Rube Goldberg contraption, with special rules for this and not for that, all evolved, rather haphazardly, to help us survive and reproduce. It consists of a hodgepodge of specialized systems.
In the front of our head is the new brain, which is a general-purpose learning and reasoning machine and a system that tries to control the impulses of the older brain. It’s a slow, deliberate planner and imaginer. Jazz improvisers quiet this part of their brain before performing.2 This part of the brain is not built to do specific jobs; rather it’s built to learn to do, well, just about anything. Where the old brain looks different depending on where you look, the new brain (particularly the cerebral cortex), looks remarkably similar no matter where you look. We have an old brain for the same reasons all animals do. We have the new brain because our ancestors got into an intelligence arms race with each other.
Because the old and new brains think with different rules, care about different things, and might even use different stores of knowledge, they often come up with different evaluations of the same situations. For example, there is a famous moral-reasoning experiment run by psychologist Joshua Greene that asks whether or not it is morally acceptable to pull a switch that will cause a train to kill one person rather than five (this is a version of a problem first proposed by Philippa Foot in 1967). Most people answer yes, such an action is acceptable, which indicates relatively high activation in the newer, more frontal areas. More emotionally salient problems, such as a version of the same problem that would require the pushing of a single person onto a track to save five people, show activation in the emotional, older parts of the brain. In this kind of scenario, where there is direct physical contact involved, people often report that doing so is morally unacceptable.3
When the new brain pulls in the opposite direction from the old, you can literally be of two minds about something. For example, your new brain can know that prepackaged cupcakes are unhealthful, but your old brain can be quite insistent that they should be devoured. Many of them. With a cold glass of milk, please. The old brain “knows” that sugar and fat are scarce and should always be eaten when the opportunity arises. Thousands of years of evolution taught it that. It doesn’t know that fat, sugar, and salt are now plentiful and contributing to an obesity problem in the industrialized world. In contrast, the new brain knows that too much sugar isn’t good for you. But who are you going to listen to? (While we’re asking, who are “you?”)
The new brain knows things because it learned them. In this case, each one of us has to learn things that run counter to what the old brain knows from evolution. Such is the source of many internal mental conflicts. The old and new have a tug of war. The new brain thinks more logically, in a step-by-step way. The old brain is not deliberative; it is intuitive. Sometimes we can get a strong, immediate sense that something is immoral. This is the old brain’s influence. Then, when asked to explain it, we must engage our new brains, which struggle, often unsuccessfully, to apply what we “believe” about morality to justify the feeling. This is what moral psychologist Jonathan Haidt called “moral dumbfounding.” Similarly, when choosing an immediate versus a delayed reward, the emotional part of the brain—the old brain—is active when thinking about the immediate reward, as are the frontal areas—the new brain—for the delayed reward. It could be that because we have some control over the activity of our frontal areas, we can use it to override the emotional areas when we need to. The everyday term for this would be “resisting temptation.”
Because the old brain is better at context and the new brain better at rules, there is evidence that people with low working memory (people who can’t remember long strings of numbers, for example) are actually better at some tasks that require old-brain function, particularly complex categorization tasks, as shown in a study by psychologist Maci DeCaro.4 The new brain uses its laser focus to attend to only a few attributes of a situation. The old brain, in contrast, has a more diffuse focus, giving lots of information more or less equal weight.
We often personally identify with the workings of our new brain. When we see a scary monster depicted in a movie, we say we don’t “believe” that the monster is there. However, as philosopher Tamar Szabó Gendler points out, some part of our brains must believe it’s there, or we wouldn’t get scared at all.5
What does this have to do with compellingness? Often the evaluations by our old brain make us prefer certain ideas and experiences. In general, its processes are black boxes, inaccessible to consciousness.
Intuition can feel like a burst of insight that comes from nowhere. What is really happening is that unconscious processes generate judgments and feelings that bubble up to consciousness fully formed. For example, you might get a feeling of danger or trust. You are aware of their outputs, but you can’t look inside yourself to see how they work. If your mind is like an ocean, your conscious mind is just the surface of the water. Because you don’t know what causes these feelings in your own head, it can feel like divine intervention or psychic ability.
We call these unconscious convictions and feelings intuition.
Should you trust your intuition? These unconscious processes either evolved or were learned for some reason or another, and you often cannot tell in the moment whether those reasons apply to your current situation. If you justify the feeling with reasons, those reasons are a confabulation that your conscious mind has invented.
It is not clear what the relationship is between trusting your intuition and belief in the paranormal and in conspiracy theories. However, a study by psychologist Matthew Boden showed that people who trust their hunches were more likely to have “ideas of reference,” which are beliefs that things in the world relate directly to them—such as that someone got on the elevator because they were in it or that the raindrops are trying to send them a message.6 Ideas of reference are common symptoms of mental illnesses such as mania and schizophrenia.

People have an understandable desire to comprehend the world around them. At its best, news holds people, governments, and other groups accountable for trespasses, and it is a purveyor of important information. At its worst, news plays to our hopes and fears, terrifying us without justification. Psychologists Hank Davis and S. Lyndsay McLeod conducted a large study that asked people to sort news stories published between 1700 and 2001 into classifications of their own choosing. The 12 categories that emerged corresponded to things we have evolved to find important, such as reputation, treatment of offspring, good deeds, violence, and sexual assault.7 News has always been sensational. As terrorism expert Scott Atran says, “Media and publicity are the oxygen of terrorism. Without them, it would die.”8 Reports of terrorism increase fear and anger, and lessen feelings of forgiveness, found a study by psychologist Alice Healy. Watching nonfiction crime documentaries makes people think the national crime rate is increasing and makes them less confident in the criminal justice system. People who watch less TV are more accurate judges of risks.9 Unfortunately, we are most likely to remember the least likely events.
What can our desire to know things about the world, and about people, tell us about our interest in fiction?
Finding Nemo is an animated movie about a father clownfish trying to find his son who gets lost. I remember marveling at the fact that this film brought tears to my eyes within five minutes. Let’s examine the drastic differences between watching this film and witnessing a real-life tragic event. First, one is watching a film, not actual, physical people. Second, it’s about filmed fish, not filmed people. Third, the fish are animated by computer programs. That is, it is not a film recording of real fish. Fourth, it’s not even about real fish—the characters are completely fictional. Reflect for a moment on the absurdity of somebody (me) crying over a screen representing fictional fish spawned by computer graphics.
Long ago, our ancestors saw very few things that were not what they appeared to be. Some notable exceptions would be mirages, reflections of objects in liquid, dreams, echoes, and how a stick appears to bend when placed in water. But most of the time, if you saw a person, there was actually a person there. A sense’s “proper domain” is that which it was designed (by evolution) to understand. But the “actual domain” is anything that triggers it. In contrast, the modern world constantly exposes us to images and sounds depicting things that are not right in front of us. We are exposed to people, but also representations of people that we substitute for the real thing. When we see someone on television say she likes ice cream, we believe that the actual person represented likes ice cream, not merely her televised image. We hear voices of people who are not present on the radio, on podcasts, and on the phone. We see events and people animated on screens. We see photos in magazines and on billboards. Of course the photo is real, but the image of the person in the photo is not. It might be that fully seeing nonreal things as they truly are—for example, seeing a picture of a woman only as a piece of paper and ink—is, in the long run, evolutionarily adaptive, just as it might be worth a designer’s time to try to get the grocery store door not to open for dogs. The door was designed to open for people (the proper domain) but opens for dogs too (part of the actual domain). Environments, however, be they cultural, technological, or natural, can change so fast that evolution can’t keep up. Photography was developed so recently that there simply has not been enough time for evolution to make the older parts of our mind good at distinguishing, say, actual people from pictures of people.
This contrast between what you know is true and what you perceive has a similar effect in optical illusions. We experience one thing, but in some sense “know” that the experience isn’t real. Consider this effect for a moment, because its meaning is profound and its ramifications great. Although we all have experience with optical illusions, it’s important to appreciate that we have no control over their effects on us. We “know” that the lines are the same length, but we still perceive them to be different. Optical illusions are designed to put your brain in this befuddled state of affairs. Your early visual system is being tricked and no amount of convincing from your deliberate thinking processes can make the visual system interpret it otherwise.
A similar effect is occurring whenever you perceive representations in any art form. Your old brain (and your perceptual areas) believes that what you’re experiencing is real and often your new brain knows better at the same time.
Films are multimedia experiences that at least appear to depict real people, in that the light patterns that play on our retinas resemble the patterns that we’d get if we were looking at real people. But literature is even more mysterious in that we can become fully engaged when we are being exposed merely to words. Language-based narrative arts have an even greater chance to capture our attention than visual arts, because language is devastatingly effective at communicating the nuances of social changes, mental states, and relationships. Here are six words (sometimes attributed to Hemingway) that I’m sure will stir the emotions of a good percentage of readers: For sale. Baby shoes. Never worn. How can six words pack such a punch? Philosophers call our emotional response to fictional characters the “paradox of fiction.” Why would the part of our minds that wants to understand our actual peers get excited when reading a book or looking at what is obviously a static painting?
We’ll begin by looking at why people engage in oral storytelling, the likely precursor to literature. One of the fabulous things about language is that it allows us to communicate the lessons we’ve learned. Without communication, learning can only occur through direct personal experience or direct observation of others. Unfortunately, some important lessons, such as the dangers of wandering into enemy territory or the deadliness of getting caught in front of an avalanche, are costly to learn by trial and error, as the learner is likely to die during or shortly after the event they would be learning from. However, with language, a lesson learned by a single individual can be communicated to a great number of people. Not only can a lone surviving individual tell her tale, but others can tell it at second and third hand. Lessons can be communicated throughout an entire culture, sometimes lasting generations. It is likely that the communication of wisdom was the original function of storytelling. As philosopher of art Denis Dutton eloquently put it, “stories provide a low-cost, low-risk surrogate experience.”10
Modern humans can tell and appreciate fictional stories, be they crafted entertainment or outright lies. However, we still learn from and take to heart these made-up stories because we’ve evolved, culturally or genetically, to do so, often without even intending to. Psychologists Elizabeth Marsh and Lisa Fazio ran a study that found that people do not spontaneously keep an eye out for falsehoods.11
If we don’t know whether a story we hear is truth or fiction, or some combination thereof, perhaps we will believe some part of it, just in case it contains some useful information. For example, a story about a bear attack might make us wary of approaching an actual bear, whether we know the story to be true or not. What about stories that we know are fiction, either because they are explicitly labeled as such, or, like The Wonderful Wizard of Oz, because they are simply too fantastic to believe? Although each of us feels as though our own mind were a single entity, under the hood of consciousness different parts of our brain fight for their points of view like argumentative parliament members. In the case of fiction, the old brain might believe the story even if the new brain doesn’t.

In this book I present a unified explanation of compellingness. Riveting things appeal to the foundations of compellingness. Those foundations are:
So how do these foundations explain what we find riveting?
* * *
First, the arts. I will mostly focus on folk and pop art, as I believe they better exemplify what people actually like, as opposed to fine arts, which are subject to intellectualizing by specialists and as such have the potential to be further removed from our natural and general cultural proclivities.
Why do people like to experience art (and things we experience in an artlike way) and how does art affect them?
Compelling art works because it reliably creates experiences in audience members. David Byrne reflects on creating music in this way: “Making music is like constructing a machine whose function is to dredge up emotions in performer and listener. . . . I’m beginning to think of the artist as someone who is adept at making devices that tap into our shared psychological make-up and that trigger the deeply moving parts we have in common.”12 What’s important is the artistic experience, which happens in the mind of the audience. It’s a reaction.
Some might think that understanding why people like visual art is impossible because beauty is in the eye of the beholder. But as psychologist of art Ellen Winner points out, there is considerable agreement in aesthetic preferences, even among people of different sexes, intelligence, personality traits, and culture. There are indeed differences, but our similarities are undeniable.13
We tend to find beautiful images that show us a world that, were we actually in it, would be a great place to be. Even compelling nonrepresentational images are liked as a result of sharing patterns with real-world things that we prefer to be in the presence of. This covers more than just art. Seeing a beautiful vista or a sunrise can elicit the same kind of response, for the same reasons. The Dinka people, in east Africa, create almost no visual art, but they appreciate the markings on cattle.14
Our preferences for landscapes reflect our desires for safety, information, and resources. As we will see, certain colors produce primal, cross-cultural reactions. As social creatures we like to see other people in images. As sexual creatures, we like to see attractive people.
We find disturbing images compelling, since they tend to hint at dangerous, important information. Even if we are horrified, we can’t look away, much like rubbernecking drivers on the highway who must slow down to see what happened at an accident site. We either like to see images that show the world as we would like it to be, or as we strongly would prefer it not to be. It’s the middle area that’s boring—the anti–sweet spot between hope and fear.
When we see visual patterns, we are delighted, because seeing a pattern is noticing a predictable regularity in the world that we might be able to exploit. Patterns are breaks in the chaos. Visual rhymes, repeated colors, symmetry, and the repetition of symbols in a painting or a series of photographs attract us.
If we see something too often, or the patterns viewed are too familiar, we get bored. We need challenges to maintain our interest—the enigmatic Mona Lisa smile, an unexplored territory, or some other incongruity. There is a sweet spot between pattern and incongruity. An image is boring if it’s too simple or too complex.
The location of this sweet spot differs from person to person, and perhaps even from mood to mood. The more familiar one is with an art form or style, the more incongruity is allowed. Everyone can appreciate Norman Rockwell, but it takes some knowledge to appreciate Chinese calligraphy or Jackson Pollock’s drip paintings. Some paintings have surface patterns that are easy to appreciate, but further investigation reveals deeper incongruities for the audience to resolve. As people grow in expertise, they can detect more features and appreciate the art more.
* * *
Because they involve visuals as well as words, the performing arts and film are at the crossroads of literature and the visual arts. Even more than in painting and photography, they are about people. Nearly all films and live performances involve human or humanlike characters, ones that appeal to our desire to observe people in any situation.
Like paintings and photographs, films and performances include visual motifs that are played out over time as well as in space, appealing to the “pattern” compellingness foundation. For example, several dancers might be doing the same motions at the same time or similar movements at different times. Ballet has a vocabulary of moves. A film might use a limited palette of colors, thereby increasing the familiarity.
Our love for incongruity influences a film’s or a performance’s appeal as well. The works range from simple to incomprehensibly complex, all to be appreciated by different audiences, in different moods, at different times. We can stand extreme incongruities for only a short period of time, allowing music videos to be more avant-garde than feature-length films. This is why absurdist full-length theater is sometimes difficult for the general public to appreciate.
* * *
The narrative arts include any art form that uses a story element, such as theater and theatrical improvisation, novels, films, contemporary (urban) legends, tabletop role-playing games, and many computer games. People also find meaning in their lives by constructing them as narratives.15
Our obsession with people plays out most strongly in narrative, where conflicts between characters are ubiquitous. When we learn about the lives of characters, our old brains react as though the characters were real people, and we try to learn lessons from them. In fact, reading fiction has been found to correlate with empathy and unselfish behavior. White children who read stories with African American characters had improved attitudes toward African Americans—not only more than kids reading stories about white children, but more than children who interacted with real African American children on a shared task!
In one study, children who read stories without descriptions of mental states (e.g., “Jill was happy”) did better at a test of understanding mental states of other people than children who read stories with such descriptions. One explanation of this fascinating finding is that forcing the audience to make inferences themselves prepares them better for reasoning about other people than having conclusions handed to them.16
We learn from narratives—for better or worse—whether we want to or not. Unrealistic human interaction depicted in narratives can cause problems of understanding humanity. Readers of romance, for example, probably believe more strongly in the “swept away by romance” trope. Research by psychologists Marsh and Fazio found that they have negative ideas about using condoms, have used them less in the past, and plan to use them less in the future.17 Just as we take care of what food we put into our bodies, we should take care what narratives we put into our minds.
* * *
There is no human society without some musical tradition.18 Nearly all social religious rituals use music. Our reactions to music, though they differ by culture, appear to have some cross-cultural similarities, including the perception of emotional tone. The metaphors we attach to music (high pitches being happy, for example) might be cross-cultural.
Our desire for understanding, and our desire to detect patterns, is clearly manifested in music, where repetition is crucial. Repetition happens in music at multiple levels, from a constant drum beat to the recognizable elements that make up a musical style or genre. Where we often get a sense immediately if we like a painting or not, many of us have learned that music, although we sometimes get a strong reaction at first, often takes repeated listenings before we know for sure whether we like it or not. Music is meant to be heard again and again. One can acceptably love a novel that one has only read once, but we are surprised if we hear of someone speak of a song he or she likes, but has only chosen to listen to once.
* * *
Some sports—such as acrobatics, figure skating, cheerleading, synchronized swimming, martial arts, parkour, and competitive ballroom dancing—occupy a gray area between games and art. Though sports are not considered art, there can be no doubt that our enjoyment of sports involves aesthetic appreciation, and that some sports, such as synchronized swimming and figure skating, tread the art/sport border. But even prototypical sports, such as basketball and soccer, share similarities with an artistic performance: people take pleasure in watching it, skill is involved with the performance, critics analyze it afterward, and there is a strong emotional response.
Much like narratives, sports involve people in conflict. Sports in which two or more players are competing directly with one another (e.g., tennis and lacrosse) might be appreciated because they represent, deep in our minds, interpersonal conflict, where solitary sports (e.g., weightlifting and archery) are appreciated for the same reasons the “man versus nature” model of plotting are.
Team sports trigger our sense of loyalty, one of the foundations of moral psychology. People align themselves, in their minds, with a team, and feel joy when it succeeds and sorrow when it loses. Loyalty matters to men and to women, but men tend to be loyal to coalitions and women to two-person relationships.19 This would predict that men prefer team sports relatively more than women do.
Our love for repetition is satisfied with the ritual aspect of the rules, such as the dropping of the puck between two hockey players or the foul shot in basketball. At the same time, sports always involve a kind of incongruity, in the form of uncertainty: even if two teams play each other again and again, no two games are ever the same. Within the restricted bounds of the rules, endless variations fascinate us. Some sports have different levels of strategy to them. American football, for example, involves much more strategy than, say, basketball, soccer, or racing. The players all stop and execute plays that are carefully practiced and memorized beforehand. Many other sports have only tactics, in-the-moment decisions based on the chaotic state of the field. American football is rewarding at the tactical level of throws and tackles, but rewards the careful observer with another layer of strategy.
The reasons we actually play sports mirror the reasons that we watch them (such as the appreciation of competition). We also play sports for the same reasons we play at all. We evolved to enjoy practice of things that resemble real-world skills, such as fighting, hiding, and escape.
It used be that sports were played more than watched, but with the advent of mass communication, most people are spectators. I predict there will be a similar shift in computer games. It might never be that people spend more time watching than playing computer games, but the spectator aspect of it is growing, with public computer game competitions that attract spectators starting to pop up.
Perhaps the most important aspect to our understanding of compellingness is its effect on what we believe. We hear ideas from people all the time, and we are constantly evaluating them and choosing, either consciously or not, how much to believe them. Much of what we believe is justified, either based on unbiased perceptions (e.g., your belief that you are currently reading a book), rational inference (you figured something out), expert testimony (trusting in scientific consensus), and so on. An examination of these rational ways to believe has been explored in other books. Unfortunately, there are a great many irrational faculties at work as well. What we’ve learned in our lives, and what we have evolved to find interesting, contributes to aesthetic qualities that influence the believability of ideas.
Take conspiracy theories. We want explanations for events (because our love for incongruity attracts us to puzzles to be solved) and we love the fact that a conspiracy theory provides one (appealing to our love for patterns and resolutions to those incongruities). Some conspiracy theories are true, such as the one surrounding Nixon and Watergate. My point isn’t that conspiracy theories are never true, but that they have compelling qualities that should make us particularly cautious about them.
We have a bias to attend to information that supports the beliefs we already have. The theorist believes he or she has figured something out that the rest of the world doesn’t understand, which provides a sense of superiority. Threats to what we believe—whether it’s conspiracy theories or religious beliefs—cause us to evangelize, to try to convince others of whatever idea is under threat. If other people agree with us, the discomfort of the threatening information is thereby reduced. Evangelism results in repeated exposure in the media, which causes an availability cascade. When we hear ideas over and over, they gain plausibility through familiarity.20
The contemporary mythology of alien abduction is, at its heart, a conspiracy theory with a science-fiction twist. Indeed, belief in a government cover-up often goes hand in hand with the alien-visitation myth.
Aliens are person-like, appealing to our love of anthropomorphic explanations. In particular, they are persons interested in sex and violence. In addition, the alien myth has the benefit, in the minds of its adherents, of lacking the supernatural touch that makes many of those same people dismiss religion and belief in demons and spirits as ridiculous. This gives believers a sense that their belief system fits better with the scientific worldview (which, in some ways, it does).
So-called alien abductees form support groups that recirculate bad ideas the way a building with no external intake circulates stale air.
Paranormal beliefs are those that violate the fundamental and scientifically founded principles of nature. This distinguishes them from beliefs that are merely wrong, such as believing that the dog has been walked when she hasn’t, or that men and women have differences in average IQ.
Using the new-brain/old-brain distinction mentioned above, many supernatural beliefs arise from biases from our old, intuitive brain. Indeed, people who use intuition more usually hold more superstitious, religious, and paranormal beliefs than others.21
Astrology, superstitions, the alien-abduction myth, and most religions benefit from being about people or personified forces. People at the empathic end of the autism spectrum are more prone to these beliefs, as they are more interested in other human beings.
Beliefs based on poor science play on our hopes and fears. They can promise us a just world, an afterlife of happiness, or miracle cures to our ills, and they can scare us with hidden dangers in the universe that we are too terrified to dismiss, leading to concrete consequences. For example, fears of vaccination have now manifested into a threat to public health.
Particularly in chaotic, unpredictable environments, we struggle to understand the world and come up with superstitions and false pattern matches to guide us. Once an idea takes hold, we stop looking for disconfirming evidence, and we start to see evidence of the superstition everywhere.
There is abundant evidence that, good or bad, religion is compelling. And it’s not that just any strange belief will catch on. There is a limited catalog of possible religious beliefs that will last, because they can only be compelling in certain ways. The explanation of why that is so involves all the hypotheses in this book. I will show how certain mental disorders correlate with religion (mania, obsessive-compulsive disorder, schizophrenia, and temporal-lobe epilepsy all feature hyperreligiosity). Mental and brain disorders also might have influenced the evolution of religion in human culture. But the fact that all cultures have religion shows that one need not have a mental disorder to be religious. The famous Minnesota twins study found that 47 percent or more of religiosity is—brace yourself—genetic.22 How you are raised only affects 11 percent of the variance of religiosity. Go ahead and read that again if you have to—I certainly did when I first came across it.
I will also spend a good bit of time discussing various religious beliefs and experiences, but I don’t want to scare off readers who are religious. No matter what your religion is, there are many adherents to the literally thousands of other religions you don’t believe in. I guarantee you that there will be some religions in the world that will sound bizarre to you, and you can legitimately wonder “how can people possibly believe that?” Even religious people wonder about the beliefs of other religious people.

Some people don’t think we should study things like art and religion. The frivolity critique often comes from scientists who look down on studying the arts or religion. The protectionism critique objects to the project out of fears that its success will take jobs away from human artists. The spoiler critique holds that I will squeeze all the beauty out of art by understanding what makes it work. The impossibility critique is that the entire endeavor of understanding the workings of compelling experiences (particularly art) is impossible. I’ll address these concerns here.
Religion and the arts are frivolous, unimportant things. Studying them is a waste of time. The creation and consumption of art comprises a major portion of our lives. Young Americans spend about seven and a half hours every day consuming artistic media. The creation of art is also important to us, as self-expression, as therapy, and as a way to attract mates. To get the stress-reduction benefits of five hours of post-work decompression, you only have to look at art for forty minutes,23 and listening to music is the most popular means for relieving stress.
Anything we spend that much time attending to and that can affect us so greatly is worth some study.
Moving on to religion and other belief systems, ideas (both good and bad) spread like viruses throughout populations of people. Though belief systems involving the paranormal and quack medicine are easily dismissed by scholars, the belief in such things in the general populace is shockingly widespread. More than 40 percent of Americans believe in ghosts, devils, and spiritual healing.24 Religion is found in every human culture, a feature that is shared with only a few other phenomena: language, tool making, and art (including music). Religious ideas are a major factor in the beliefs and behavior of peoples around the world.
Technology will take jobs from artists. Technological progress has put machines in the roles that used to be taken by laborers. Typically, this brings people out of physical labor and creates new white-collar jobs. We are already at the point where computers are starting to take over intellectual jobs as well. The original meaning of computer was a person who did computations by hand. This trend will surely continue, and people will be working in higher-level jobs that manage machines working at the lower levels.
I predict that as computers gain expertise in creative areas, particular jobs will start disappearing, just as cel animation (cartoons made by drawing rather than using computer graphics) is disappearing now. That is not to say that there will be no human-made art. People will make it for the intrinsic pleasure of it, much like poetry is made today.
Will computer programs of the future be able to do everything the people of today can do, and better? I think so, but I also think that there will be a computer-machine synthesis that will render the human-computer distinction irrelevant. It also might be that by the time computers are better at everything than we are, there will be no need to work at all. I should note that there are smarter people than me on both sides of this debate as well. Time will tell.
If computer programs can create worthwhile works of art cheaply and quickly, art consumers (that is, everybody) will benefit enormously. Perhaps films can be customized to be exactly what I’d most want to see given the day I’ve had and feature themes reflective of ideas I’ve been wrestling with lately.
You’re a spoiler: you’ll squeeze all of the beauty out of art by understanding what makes it work. Poet John Keats lamented that Isaac Newton’s theories had “unwoven the rainbow” and ruined the beauty of color and light through his investigations. Keats died in 1821, but in my (admittedly nonscientific) casual observation of arts and advertising, artists and designers are still using color with some effectiveness. This understanding of how something works offers its own kind of beauty. For example, people like landscape scenes that appear to be looking out from a partial shelter (e.g., tree branches). I think this is because the branches make us feel safe, which is a beautiful thought in itself, and enhances and deepens our appreciation of a given landscape painting or photograph. Is sex any less fun because we know it evolved for reproductive purposes? Are cupcakes any less delicious because we know we evolved to like sweets because sugar was nutritious and rare in our evolutionary environment? It sure doesn’t feel like it. When I started writing this book I believed that explanation wouldn’t change the feeling of appreciation.
However, one of the humbling things about putting your trust in science is how often you find yourself to be wrong: a study by business professor Sarah Moore showed that explaining why you like the taste of a cupcake diminished the love for the taste. She also found that explaining why an experience was horrible reduced the remembered horribleness.25 Another study, supervised by psychologist Daniel Gilbert, showed that a complete understanding of a positive event reduces the felt pleasure, as well as its duration.26 So, for example, if someone asks you why you liked a movie, simply trying to explain why will probably reduce your pleasure of having watched it. Understanding seems to reduce the emotional strength of an experience, which works in our favor for negative things (recovery from trauma), but can hinder our pleasure for positive things (like eating cupcakes).
I was wrong, and I cannot now write a knock-down rebuttal to the spoiler critique. The best I can say is that even though your pleasure might take a hit, I hope that the explanations themselves are sufficiently interesting that, given the gains and losses, it is worth it.
There is one kind of entertainment that is clearly hindered by understanding: magic tricks. The reason magicians don’t explain how their tricks are done is because this knowledge ruins the effect of the trick. Your mind’s search for understanding is part of why the trick is so enjoyable.
Compare this to how much more we appreciate some things when we find out how they work: the joy of discovery when we unravel a mystery, or when we learn that the pony fish illuminates its belly so as to be invisible to predators below.
Finally, there are those who think that an understanding of things like art and religion is impossible. We’ll see.
