The Shallows: What the Internet Is Doing to Our Brains
Although neuroplasticity provides an escape from genetic determinism, a loophole for free thought and free will, it also imposes its own form of determinism on our behavior. As particular circuits in our brain strengthen through the repetition of a physical or mental activity, they begin to transform that activity into a habit. The paradox of neuroplasticity, observes Doidge, is that, for all the mental flexibility it grants us, it can end up locking us into rigid behaviors.33 The chemically triggered synapses that link our neurons program us, in effect, to want to keep exercising the circuits theyve formed. Once weve wired new circuitry in our brain, Doidge writes, we long to keep it activated.
And what the Net seems to be doing is chipping away my capacity for concentration and contemplation. Whether Im online or not, my mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles.
Culture is sustained in our synapses...It's more than what can be reduced to binary code and uploaded onto the Net. To remain vital, culture must be renewed in the minds of the members of every generation. Outsource memory, and culture withers.
Even the earliest silent readers recognized the striking change in their consciousness that took place as they immersed themselves in the pages of a book. The medieval bishop Isaac of Syria described how, whenever he read to himself, as in a dream, I enter a state when my sense and thoughts are concentrated. Then, when with prolonging of this silence the turmoil of my memories is stilled in my heart, ceaseless waves of joy are sent me by inner thoughts, beyond expectation suddenly arising to delight my heart. Reading a book was a meditative act, but it didnt involve a clearing of the mind. It involved a filling, or replenishing, or the mind. Readers disengaged their attention from the outward flow of passing stimuli in order to engage it more deeply with an inward flow of words, ideas, and emotions. That wasand isthe essence of the unique mental process of deep reading.
Even though the World Wide Web has made hypertext commonplace, indeed ubiquitous, research continues to show that people who read linear text comprehend more, remember more, and learn more than those who read text peppered with links.
Experiments show that just as the brain can build new or stronger circuits through physical or mental practice, those circuits can weaken or dissolve with neglect.
In a talk at a recent Phi Beta Kappa meeting, Duke University professor Katherine Hayles confessed, I cant get my students to read whole books anymore.10 Hayles teaches English; the students shes talking about are students of literature.
In the quiet spaces opened up by the prolonged, undistracted reading of a book, people made their own associations, drew their own inferences and analogies, fostered their own ideas. They thought deeply as they read deeply.
lawyer and technology writer Richard Koman, argued that Google has become a true believer in its own goodness, a belief which justifies its own set of rules regarding corporate ethics, anti-competition, customer service and its place in society.
media arent just channels of information. They supply the stuff of thought, but they also shape the process of thought. And what the Net seems to be doing is chipping away my capacity for concentration and contemplation. Whether Im online or not, my mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles. Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.

our conventional response to all media, namely that it is how they are used that counts, is the numb stance of the technological idiot, he wrote. The content of the medium is just the juicy piece of meat carried by the burglar to distract the watchdog of the mind. P 4
[Patricia Greenfield] concluded that every medium develops some cognitive skills at the expense of others. Our growing use of the Net and other screen-based technologies has led to the widespread and sophisticated development of visual-spatial skills. We can, for example, rotate objects in our minds better than we used to be able to. But our new strengths in visual-spatial intelligence go hand in hand with a weakening of our capacities for the kind of deep processing that underpins mindful knowledge acquisition, inductive analysis, critical thinking, imagination, and reflection.
Quite a few people still listen to vinyl records, use film cameras to take photographs, and look up phone numbers in the printed Yellow Pages. But the old technologies lose their economic and cultural force. They become progresss dead ends. Its the new technologies that govern production and consumption, that guide peoples behavior and shape their perceptions. Thats why the future of knowledge and culture no longer lies in books or newspapers or TV shows or radio programs or records or CDs. It lies in digital files shot through our universal medium at the speed of light.

The bond between book reader and book writer has always been a tightly symbiotic one, a means of intellectual and artistic cross-fertilization. The words of the writer act as a catalyst in the mind of the reader, inspiriting new insights, associations, and perceptions, sometimes even epiphanies. And the very existence of the attentive, critical reader provides the spur for the writers work. It gives the author confidence to explore new forms of expression, to blaze difficult and demanding paths of thought, to venture into uncharted and sometimes hazardous territory. All great men have written proudly, nor cared to explain, said Emerson. They knew that the intelligent reader would come at last, and would thank them.
The faster we surf across the surface of the Webthe more links we click and pages we viewthe more opportunities Google gains to collect information about us and to feed us advertisements. Its advertising system, moreover, is explicitly designed to figure out which messages are most likely to grab our attention and then to place those messages in our field of view. Every click we make on the Web marks a break in our concentration, a bottom-up disruption of our attentionand its in Googles economic interest to make sure we click as often as possible.
The internet, as its proponents rightly remind us, makes for variety and convenience; it does not force anything upon you. Only it turns out it doesnt feel like that at all. We dont feel as if we had freely chosen our online practices. We feel instead that they are habits we have helplessly picked up or that history has enforced, that we are not distributing our attention as we intend or even like to
The more a sufferer concentrates on his symptoms, the deeper those symptoms are etched into his neural circuits. In the worst cases, the mind essentially trains itself to be sick. Many addictions, too, are reinforced by the strengthening of plastic pathways to the brain. Even very small doses of addictive drugs can dramatically alter the flow of neurotransmitters in a persons synapses, resulting in long-lasting alterations in brain circuitry and function. In some cases, the buildup of certain kinds of neurotransmitters, such as dopamine, a pleasure-producing cousin to adrenaline, seems to actually trigger the turning on or off particular genes, bringing even stronger cravings for the drug. The vital path turns deadly.
The Nets interactivity gives us powerful new tools for finding information, expressing ourselves, and conversing with others. It also turns us into lab rats constantly pressing levers to get tiny pellets of social or intellectual nourishment.
The Web provides a convenient and compelling supplement to personal memory, but when we start using the Web as a substitute for personal memory, bypassing the inner processes of consolidation, we risk emptying our minds of their riches.
To remain vital, culture must be renewed in the minds of the members of every generation. Outsource memory, and culture withers.
We become, neurologically, what we think."(33)
We dont constrain our mental powers when we store new long-term memories. We strengthen them. With each expansion of our memory comes an enlargement of our intelligence. The Web provides a convenient and compelling supplement to personal memory - but when we start using the Web as a substitute for personal memory, by bypassing the inner processes of consolidation, we risk emptying our minds of their riches.
We want to be interrupted, because each interruption brings us a valuable piece of information. To turn off these alerts is to risk feeling out of touch, or even socially isolated.

When a printed bookwhether a recently published scholarly history or a two-hundred-year-old Victorian novelis transferred to an electronic device connected to the Internet, it turns into something very like a Web site. Its words become wrapped in all the distractions of the networked computer. Its links and other digital enhancements propel the reader hither and yon. It loses what the late John Updike called its edges and dissolves into the vast, rolling waters of the Net. The linearity of the printed book is shattered, along with the calm attentiveness it encourages in the reader.
When our brain is overtaxed, we find distractions more distracting.
You can take a book to the beach without worrying about sand getting in its works. You can take it to bed without being nervous about it falling to the floor should you nod off. You can spill coffee on it. You can sit on it. You can put it down on a table, open to the page youre reading, and when you pick it up a few days later it will still be exactly as you left it. You never have to be concerned about plugging a book into an outlet or having its battery die.
