How reading rewires your brain for higher intelligence and empathy
Get lost in a good book. Time and again, reading has been shown to make us healthier, smarter, and more empathic.
Fitness headlines promise staggering physical results: a firmer butt, ripped abs, bulging biceps. Nutritional breakthroughs are similar clickbait, with attention-grabbing, if often inauthentic—what, really, is a “superfood?"—means of achieving better health. Strangely, one topic usually escaping discussion has been shown, time and again, to make us healthier, smarter, and more empathic animals: reading.
Reading, of course, requires patience, diligence, and determination. Scanning headlines and retweeting quips is not going to make much cognitive difference. If anything, such sweet nothings are dangerous, the literary equivalent of sugar addiction. Information gathering in under 140 characters is lazy. The benefits of contemplation through narrative offer another story.
The benefits are plenty, which is especially important in a distracted, smartphone age in which one-quarter of American children don't learn to read. This not only endangers them socially and intellectually, but cognitively handicaps them for life. One 2009 study of 72 children ages eight to ten discovered that reading creates new white matter in the brain, which improves system-wide communication.
White matter carries information between regions of grey matter, where any information is processed. Not only does reading increase white matter, it helps information be processed more efficiently.
Reading in one language has enormous benefits. Add a foreign language and not only do communication skills improve—you can talk to more people in wider circles—but the regions of your brain involved in spatial navigation and learning new information increase in size. Learning a new language also improves your overall memory.
In one of the most fascinating aspects of neuroscience, language affects regions of your brain involving actions you're reading about. For example, when you read “soap" and “lavender," the parts of your brain implicated in scent are activated. Those regions remain silent when you read “chair." What if I wrote “leather chair?" Your sensory cortex just fired.
Continuing from the opening paragraph, let's discuss squats in your quest for a firmer butt. Picture the biomechanics required for a squat. Your motor cortex has been activated. Athletes have long envisioned their movements—Serena Williams's serve; Conor McGregor's kicks; Usain Bolt's bursts of speed—to achieve better proficiency while actually moving. That's because their brains are practicing. That is, they're practicing through visualization techniques.
Hard glutes are one thing. Novel reading is a great way to practice being human. Rather than sprints and punches, how about something more primitive and necessary in a society, like empathy? As you dive deeper into Rabbit Angstrom's follies or Jason Taylor coming of age, you not only feel their pain and joy. You actually experience it.
In one respect novels go beyond simulating reality to give readers an experience unavailable off the page: the opportunity to enter fully into other people's thoughts and feelings.
This has profound implications for how we interact with others. When encountering a 13-year-old boy misbehaving, you most likely won't think, “Well, David Mitchell wrote about such a situation, and so I should behave like this," but you might have integrated some of the lessons about young boys figuring life out and display a more nuanced understanding in how you react.
Perhaps you'll even reconsider trolling someone online regarding their political opinion, remembering that no matter how crass and inhumane a sentiment appears on screen, an actual human is sitting behind the keyboard pecking out their thoughts. I'm not arguing against engaging, but for the love of anything closely resembling humanity, argue intelligently.
Because reading does in fact make us more intelligent. Research shows that reading not only helps with fluid intelligence, but with reading comprehension and emotional intelligence as well. You make smarter decisions about yourself and those around you.
All of these benefits require actually reading, which leads to the formation of a philosophy rather than the regurgitation of an agenda, so prevalent in reposts and online trolling. Recognizing the intentions of another human also plays a role in constructing an ideology. Novels are especially well-suited for this task. A 2011 study published in the Annual Review of Psychology found overlap in brain regions used to comprehend stories and networks dedicated to interactions with others.
Novels consume time and attention. While the benefits are worthwhile, even shorter bursts of prose exhibit profound neurological effects. Poetry elicits strong emotional responses in readers and, as one study shows, listeners. Heart rates, facial expressions, and “movement of their skin and arm hairs" were measured while participants listened to poetry. Forty percent ended up displaying visible goose bumps, as they would while listening to music or watching movies. As for their craniums:
Their neurological responses, however, seemed to be unique to poetry: Scans taken during the study showed that listening to the poems activated parts of participants' brains that, as other studies have shown, are not activated when listening to music or watching films.
These responses mostly occurred near the conclusion of a stanza and especially near the end of the poem. This fits in well with our inherent need for narrative: in the absence of a conclusion our brain automatically creates one, which, of course, leads to plenty of heartbreak and suffering when our speculations prove to be false. Instead we should turn to more poetry:
There is something fundamental to the poetic form that implies, creates, and instills pleasure.
Whether an Amiri Baraka verse or a Margaret Atwood trilogy, attention matters. Research at Stanford showed a neurological difference between reading for pleasure and focused reading, as if for a test. Blood flows to different neural areas depending on how reading is conducted. The researchers hope this might offer clues for advancing cognitive training methods.
I have vivid memories of my relationship with reading: trying to write my first book (Scary Monster Stories) at age five; creating a mock newspaper after the Bernard Goetz subway shooting when I was nine, my mother scolding me for “thinking about such things"; sitting in the basement of my home in the Jersey suburbs one weekend morning, determined to read the entirety of Charlie and the Chocolate Factory, which I did.
Reading is like any skill. You have to practice it, regularly and constantly. While I never finished (or really much started) Scary Monster Stories, I have written nine books and read thousands more along the way. Though it's hard to tell if reading has made me smarter or a better person, I like to imagine that it has.
What I do know is that life would seem a bit less meaningful if we didn't share stories with one another. While many mediums for transmitting narratives across space and time exist, I've found none as pleasurable as cracking open a new book and getting lost in a story. Something profound is always discovered along the way.

What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
With just a few strategical tweaks, the Nazis could have won one of World War II's most decisive battles.
- The Battle of Britain is widely recognized as one of the most significant battles that occurred during World War II. It marked the first major victory of the Allied forces and shifted the tide of the war.
- Historians, however, have long debated the deciding factor in the British victory and German defeat.
- A new mathematical model took into account numerous alternative tactics that the German's could have made and found that just two tweaks stood between them and victory over Britain.
Two strategic blunders<p>Now, historians and mathematicians from York St. John University have collaborated to produce <a href="http://www-users.york.ac.uk/~nm15/bootstrapBoB%20AAMS.docx" target="_blank">a statistical model (docx download)</a> capable of calculating what the likely outcomes of the Battle of Britain would have been had the circumstances been different. </p><p>Would the German war effort have fared better had they not bombed Britain at all? What if Hitler had begun his bombing campaign earlier, even by just a few weeks? What if they had focused their targets on RAF airfields for the entire course of the battle? Using a statistical technique called weighted bootstrapping, the researchers studied these and other alternatives.</p><p>"The weighted bootstrap technique allowed us to model alternative campaigns in which the Luftwaffe prolongs or contracts the different phases of the battle and varies its targets," said co-author Dr. Jaime Wood in a <a href="https://www.york.ac.uk/news-and-events/news/2020/research/mathematicians-battle-britain-what-if-scenarios/" target="_blank">statement</a>. Based on the different strategic decisions that the German forces could have made, the researchers' model enabled them to predict the likelihood that the events of a given day of fighting would or would not occur.</p><p>"The Luftwaffe would only have been able to make the necessary bases in France available to launch an air attack on Britain in June at the earliest, so our alternative campaign brings forward the air campaign by three weeks," continued Wood. "We tested the impact of this and the other counterfactuals by varying the probabilities with which we choose individual days."</p><p>Ultimately, two strategic tweaks shifted the odds significantly towards the Germans' favor. Had the German forces started their campaign earlier in the year and had they consistently targeted RAF airfields, an Allied victory would have been extremely unlikely.</p><p>Say the odds of a British victory in the real-world Battle of Britain stood at 50-50 (there's no real way of knowing what the actual odds are, so we'll just have to select an arbitrary figure). If this were the case, changing the start date of the campaign and focusing only on airfields would have reduced British chances at victory to just 10 percent. Even if a British victory stood at 98 percent, these changes would have cut them down to just 34 percent.</p>
A tool for understanding history<p>This technique, said co-author Niall Mackay, "demonstrates just how finely-balanced the outcomes of some of the biggest moments of history were. Even when we use the actual days' events of the battle, make a small change of timing or emphasis to the arrangement of those days and things might have turned out very differently."</p><p>The researchers also claimed that their technique could be applied to other uncertain historical events. "Weighted bootstrapping can provide a natural and intuitive tool for historians to investigate unrealized possibilities, informing historical controversies and debates," said Mackay.</p><p>Using this technique, researchers can evaluate other what-ifs and gain insight into how differently influential events could have turned out if only the slightest things had changed. For now, at least, we can all be thankful that Hitler underestimated Britain's grit.</p>
A new study shows our planet is much closer to the supermassive black hole at the galaxy's center than previously estimated.
Arrows on this map show position and velocity data for the 224 objects utilized to model the Milky Way Galaxy. The solid black lines point to the positions of the spiral arms of the Galaxy. Colors reflect groups of objects that are part of the same arm, while the background is a simulation image.
