The Science of Storytelling

by Will Storr

  When we’re reading, hearing or watching a story we deploy our theory-of-mind skills by automatically making hallucinatory models of the minds of its characters. Some authors model the minds of their own characters with such force that they hear them talk. Charles Dickens, William Blake and Joseph Conrad all spoke of such extraordinary experiences. The novelist and psychologist Professor Charles Fernyhough has led research in which 19 per cent of ordinary readers reported hearing the voices of fictional characters even after they’d put their books down. Some reported a kind of literary possession, with the character influencing the tone and nature of their thoughts.

  But much as humans excel at such feats of theory of mind, we also tend to dramatically overestimate our abilities. Although there’s an admitted absurdity in claiming to be able to quantify human behaviour with such absolute numerical precision, some research suggests strangers read another’s thoughts and feelings with an accuracy of just 20 per cent. Friends and lovers? A mere 35 per cent. Our errors about what others are thinking are a major cause of human drama. As we move through life, wrongly predicting what people are thinking and how they’ll react when we try to control them, we haplessly trigger feuds and fights and misunderstandings that fire devastating spirals of unexpected change into our social worlds.

  Comedy, whether by William Shakespeare or John Cleese and Connie Booth, is often built on such mistakes. But whatever the mode of storytelling, well-imagined characters always have theories about the minds of other characters and – because this is drama – those theories will often be wrong.This wrongness will lead to unexpected consequences and yet more drama. The influential post-war director Alexander Mackendrick writes, ‘I start by asking: What does A think B is thinking about A? It sounds complicated (and it is) but this is the very essence of giving some density to a character and, in turn, a scene.’

  The author Richard Yates uses a theory-of-mind mistake to create a pivotal moment of drama in his classic Revolutionary Road. The novel charts the dissolving marriage of Frank and April Wheeler. When they were young, and newly in love, Frank and April dreamed of bohemian lives in Paris. But, when we meet them, middle-aged reality has struck. Frank and April have two children, with a third on the way, and have moved into a cookie-cutter suburb. Frank’s secured a job at his father’s old company and has found himself rather settling into a life of boozy lunches and housewife-at-home ease. But April isn’t happy. She still dreams of Paris. They argue, bitterly. Sex is withheld. Frank sleeps with a girl at work. And then he makes his theory-of-mind mistake.

  In order to break the impasse with his wife, Frank decides to confess his infidelity. His theory of April’s mind appears to be that she’ll be thrown into a state of catharsis that will jolt her back into reality. There’ll be tears to mop up, sure, but those tears will just remind the ol’ gal why she loves him.

  This is not what happens. When he confesses, April asks, Why? Not why he slept with the girl, but why is he bothering to tell her? She doesn’t care about his fling. This isn’t what Frank was expecting at all. He wants her to care! ‘I know you do,’ April tells him. ‘And I suppose I would, if I loved you; but you see I don’t. I don’t love you and I never really have and I never really figured it out until this week.’

  As the eye darts about, building up its story world for you to live inside, the brain’s choosy about where it tells it to look. We’re attracted to change, of course, but also to other salient details. Scientists used to believe attention was drawn simply to objects that stood out, but recent research suggests we’re more likely to attend to that which we find meaningful. Unfortunately, it’s not yet known precisely what ‘meaningful’ means, in this context, but tests that tracked saccades found, for example, that an untidy shelf attracted more attention than a sun-splashed wall. For me, that untidy shelf hints of human change; of a life in detail; of trouble insinuating itself in a place designed for order. It’s no surprise test-brains were drawn to it. It’s story-stuff, whilst the sun is just a shrug.

  Storytellers also choose carefully what meaningful details to show and when. In Revolutionary Road, just after Frank makes his changeful theory-of-mind mistake that throws his life in a new and unexpected direction, the author draws our attention to one brilliant detail. It’s an urgent voice on the radio: ‘And listen to this. Now, during the Fall Clearance, you’ll find Robert Hall’s entire stock of men’s walk shorts and sport jeans drastically reduced!’

  Both believable and crushing, it serves to intensify our feelings, at exactly the right moment, of the suffocating and dreary housewifey corner that April has found herself backed into. Its timing also implicitly defines and condemns what Frank has become. He used to think he was bohemian – a thinker! – and now he’s just Bargain Shorts Man. This is an advert for him.

  The director Stephen Spielberg is famous for his use of salient detail to create drama. In Jurassic Park, during a scene that builds to our first sighting of Tyrannosaurus rex, we see two cups of water on a car dashboard, deep rumbles from the ground sending rings over their liquid surface. We cut between the faces of the passengers, each slowly registering change. Then we see the rear-view mirror vibrating with the stomping of the beast. Extra details like this add even more tension by mimicking the way brains process peak moments of stress. When we realise our car is about to crash, say, the brain needs to temporarily increase its ability to control the world. Its processing power surges and we become aware of more features in our environment, which has the effect of making time seem to slow down. In exactly this way, storytellers stretch time, and thereby build suspense, by packing in extra saccadic moments and detail.

  There’s a park bench, in my hometown, that I don’t like to walk past because it’s haunted by a breakup with my first love. I see ghosts on that bench that are invisible to anyone else except, perhaps, her. And I feel them too. Just as human worlds are haunted with minds and faces, they’re haunted with memories. We think of the act of ‘seeing’ as the simple detection of colour, movement and shape. But we see with our pasts.

  That hallucinatory neural model of the world we live inside is made up of smaller, individual models – we have neural models of park benches, dinosaurs, ISIS, ice cream, models of everything – and each of those is packed with associations from our own personal histories. We see both the thing itself and all that we associate with it. We feel it too. Everything our attention rests upon triggers a sensation, most of which are minutely subtle and experienced beneath the level of conscious awareness. These feelings flicker and die so rapidly that they precede conscious thought, and thereby influence it. All these feelings reduce to just two impulses: advance and withdraw. As you scan any scene, then, you’re in a storm of feeling; positive and negative sensations from the objects you see fall over you like fine drops of rain. This understanding is the beginning of creating a compelling and original character on the page. A character in fiction, like a character in life, inhabits their own unique hallucinated world in which everything they see and touch comes with its own unique personal meaning.

  These worlds of feeling are a result of the way our brains encode the environment. The models we have of everything are stored in the form of neural networks. When our attention rests upon a glass of red wine, say, a large number of neurons in different parts of the brain are simultaneously activated. We don’t have a specific ‘glass of wine’ area that lights up, what we have are responses to ‘liquid’, ‘red’, ‘shiny surface’, ‘transparent surface’, and so on. When enough of these are triggered, the brain understands what’s in front of it and constructs the glass of wine for us to ‘see’.

  But these neural activations aren’t limited to mere descriptions of appearance. When we detect the glass of wine, other associations also flash into being: bitter-sweet flavours; vineyards; grapes; French culture; dark marks on white carpets; your road-trip to the Barossa Valley; the last time you got drunk and made a fool of yourself; the first ti
me you got drunk and made a fool of yourself; the breath of the woman who attacked you. These associations have powerful effects on our perception. Research shows that when we drink wine our beliefs about its quality and price change our actual experience of its taste. The way food is described has a similar effect.

  It’s just such associative thinking that gives poetry its power. A successful poem plays on our associative networks as a harpist plays on strings. By the meticulous placing of a few simple words, they brush gently against deeply buried memories, emotions, joys and traumas, which are stored in the form of neural networks that light up as we read. In this way, poets ring out rich chords of meaning that resonate so profoundly we struggle to fully explain why they’re moving us so.

  Alice Walker’s ‘Burial’ describes the poet bringing her child to the cemetery in Eatonton, Georgia, in which several generations of her family are interred. She describes her grandmother resting

  undisturbed

  beneath the Georgia sun,

  above her the neatstepping hooves

  of cattle

  and graves that ‘drop open without warning’ and

  cover themselves with wild ivy

  blackberries. Bittersweet and sage.

  No one knows why. No one asks.

  When I read ‘Burial’ for the first time, the lines at the end of this stanza made little logical sense to me, and yet I immediately found them beautiful, memorable and sad:

  Forgetful of geographic resolutions as birds

  the far-flung young fly South to bury

  the old dead.

  It’s these same associative processes that allow us to think metaphorically. Analyses of language reveal the extraordinary fact that we use around one metaphor for every ten seconds of speech or written word. If that sounds like too much, it’s because you’re so used to thinking metaphorically – to speaking of ideas that are ‘conceived’ or rain that is ‘driving’ or rage that is ‘burning’ or people who are ‘dicks’. Our models are not only haunted by ourselves, then, but also by properties of other things. In her 1930 essay ‘Street Haunting’ Virginia Woolf employs several subtle metaphors over the course of a single gorgeous sentence:

  How beautiful a London street is then, with its islands of lights, and its long groves of darkness, and on the side of it perhaps some tree-sprinkled, grass-grown space where night is folding herself to sleep naturally and, as one passes the iron railing, one hears those little cracklings and stirrings of leaf and twig which seem to suppose the silence of fields all around them, an owl hooting, and far away the rattle of the train in the valley.

  Neuroscientists are building a powerful case that metaphor is far more important to human cognition than has ever been imagined. Many argue it’s the fundamental way that brains understand abstract concepts, such as love, joy, society and economy. It’s simply not possible to comprehend these ideas in any useful sense, then, without attaching them to concepts that have physical properties: things that bloom and warm and stretch and shrink.

  Metaphor (and its close sibling, the simile) tends to work on the page in one of two ways. Take this example, from Michael Cunningham’s A Home at the End of the World: ‘She washed old plastic bags and hung them on the line to dry, a string of thrifty tame jellyfish floating in the sun.’ This metaphor works principally by opening an information gap. It asks the brain a question: how can a plastic bag be a jellyfish? To find the answer, we imagine the scene. Cunningham has nudged us into more vividly modelling his story.

  In Gone with the Wind, Margaret Mitchell uses metaphor to make not a visual point, but a conceptual one: ‘The very mystery of him excited her curiosity like a door that had neither lock nor key.’

  In The Big Sleep, metaphor enables Raymond Chandler to pack a tonne of meaning into just seven words: ‘Dead men are heavier than broken hearts.’

  Brain scans illustrate the second, more powerful, use of metaphor. When participants in one study read the words ‘he had a rough day’, their neural regions involved in feeling textures became more activated, compared with those who read ‘he had a bad day’. In another, those who read ‘she shouldered the burden’ had neural regions associated with bodily movement activated more than when they read ‘she carried the burden’. This is prose writing that deploys the weapons of poetry. It works because it activates extra neural models that give the language additional meaning and sensation. We feel the heft and strain of the shouldering, we touch the abrasiveness of the day.

  Such an effect is exploited by Graham Greene in The Quiet American. Here, a protagonist with a broken leg is receiving unwanted help from his antagonist: ‘I tried to move away from him and take my own weight, but the pain came roaring back like a train in a tunnel.’ This finely judged metaphor is enough to make you wince. You can almost feel the neural networks firing up and borrowing greedily from each other: the tender limb; the snapped bone; the pain in all its velocity and unstoppableness and thunder, roaring up the tunnel of the leg.

  In The God of Small Things, Arundhati Roy uses metaphorical language to sensual effect when describing a love scene between the characters Ammu and Valutha: ‘She could feel herself through him. Her skin. The way her body existed only where he touched her. The rest of her was smoke.’

  And here the eighteenth-century writer and critic Denis Diderot uses a one-two of perfectly contrasting similes to smack his point home: ‘Libertines are hideous spiders, that often catch pretty butterflies.’

  Metaphor and simile can be used to create mood. In Karl Ove Knausgaard’s A Death in the Family, the narrator describes stepping outside for a cigarette break, in the midst of clearing out the house of his recently deceased father. There he sees, ‘plastic bottles lying on their sides on the brick floor dotted with raindrops. The bottlenecks reminded me of muzzles, as if they were small cannons with their barrels pointing in all directions.’ Knausgaard’s choice of language adds to the general deathly, angry aura of the passage by flicking unexpectedly at the reader’s models of guns.

  Descriptive masters such as Charles Dickens manage to hit our associative models again and again, creating wonderful crescendos of meaning, with the use of extended metaphors. Here he is, at the peak of his powers, introducing us to Ebenezer Scrooge in A Christmas Carol.

  The cold within him froze his old features, nipped his pointed nose, shrivelled his cheek, stiffened his gait; made his eyes red, his thin lips blue; and spoke out shrewdly in his grating voice. A frosty rime was on his head, and on his eyebrows, and his wiry chin. He carried his own low temperature always about with him; he iced his office in the dog-days; and didn’t thaw it one degree at Christmas. External heat and cold had little influence on Scrooge. No warmth could warm, nor wintry weather chill him. No wind that blew was bitterer than he, no falling snow was more intent upon its purpose, no pelting rain less open to entreaty.

  The author and journalist George Orwell knew the recipe for a potent metaphor. In the totalitarian milieu of his novel Nineteen Eighty-Four, he describes the small room in which the protagonist Winston and his partner Julia could be themselves without the state spying on them as ‘a world, a pocket of the past where extinct animals could walk.’

  It won’t come as much of a surprise to discover the interminably correct Orwell was even right when he wrote about writing. ‘A newly invented metaphor assists thought by evoking a visual image,’ he suggested, in 1946, before warning against the use of that ‘huge dump of worn-out metaphors which have lost all evocative power and are merely used because they save people the trouble of inventing phrases for themselves.’

  Researchers recently tested this idea that clichéd metaphors become ‘worn-out’ by overuse. They scanned people reading sentences that included action-based metaphors (‘they grasped the idea’), some of which were well-worn and others fresh. ‘The more familiar the expression, the less it activated the motor system,’ writes the neuroscientist Professor Benjamin Bergen. ‘In other words, over their careers, metaphorical express
ions come to be less and less vivid, less vibrant, at least as measured by how much they drive metaphorical simulations.’

  In a classic 1932 experiment, the psychologist Frederic Bartlett read a traditional Native American story to participants and asked them to retell it, by memory, at various intervals. The War of the Ghosts was a brief, 330-word tale about a boy who was reluctantly compelled to join a war party. During the battle, a warrior warned the boy that he had been shot. But, looking down, the boy couldn’t see any wounds on his body. The boy concluded that all the warriors were actually just ghosts. The next morning the boy’s face contorted, something black came out of his mouth, and he dropped down dead.

  The War of the Ghosts had various characteristics that were unusual, at least for the study’s English participants. When they recalled the tale over time, Bartlett found their brains did something interesting. They simplified and formalised the story, making it more familiar by altering much of its ‘surprising, jerky and inconsequential’ qualities. They removed bits, added other bits and reordered still more. ‘Whenever anything appeared incomprehensible, it was either omitted or explained,’ in much the same way that an editor might fix a confusing story.

  Turning the confusing and random into a comprehensible story is an essential function of the storytelling brain. We’re surrounded by a tumult of often chaotic information. In order to help us feel in control, brains radically simplify the world with narrative. Estimates vary, but it’s believed the brain processes around 11 million bits of information at any given moment, but makes us consciously aware of no more than forty. The brain sorts through an abundance of information and decides what salient information to include in its stream of consciousness.
