网络似乎正在粉碎集中注意力和思考的能力

  “戴夫,停,停,听到了吗?停,戴夫,你停下来了吗?”这是在斯坦利·库布里克的电影《2001年太空漫游》临近结尾的一个著名而刺激的场景里,超级电脑HAL央求坚韧的宇航员戴夫·波曼时说的。在被功能出错的电脑送到死亡的外太空时,波曼镇静冷酷地切断了控制电脑人工智能的存储线路。“戴夫,我的头脑正在消逝”,HAL喊道,“我能感觉到,我能感觉到。”

  我也能感觉到。过去数年来,我一直有一种不舒服的感觉,觉得某些人或某些东西正在摆弄我的大脑,重塑中枢神经系统,重置记忆。我的大脑没有消逝,但它正在变化,我目前的思考方式与过去已经截然不同。当我阅读时,能最为强烈地感觉到这一点。全神贯注于一本书或一篇长文,曾经是易如反掌之事,我的大脑能够抓住叙述的演进或论点的转折,我曾耗费数个小时徜徉在长长的诗行里。但如今不再如此,往往阅读二三页后我的注意力就开始漂移了。我变得焦虑不安,失去了线索,开始寻找其他事情来做。我感觉我一直在力图将自己任性的大脑拽回到书本,过去曾经甘之如饴的阅读业已变成一场战斗。

  我清楚所发生的一切。10余年来,我一直花费大量时间上网,搜索和冲浪,有时候给互联网庞大的数据库增加一些东西。作为一名作家,网络对我是天赐之物。曾经需要数天泡在图书馆书堆和杂志室里的研究,现在在几分钟就能完成。通过几个Google搜索,做几下迅速的超链接点击,我就能获得讲故事的根据或精炼的词语。即便我不工作时,我也一样可能沉浸在网络的信息丛中,阅读和写电子邮件,浏览新闻标题和博客网站,看视频和听音乐,或者干脆就在一个又一个链接间点来点去。

  对我来说,网络正变成无处不在的媒介,大多数信息流穿越我的眼睛和耳朵,进入我的大脑,其他人也是如此。能够快捷地得到一个如此令人难以置信的信息库,其好处多多。《连线》杂志的克利夫·汤普森写道:“硅片记忆的完美,对思想可能是一个巨大的福音。”但是,这样的福音是花代价得到的。正如媒体理论家马歇尔·麦克卢汉在20世纪60年代指出的,媒体并非仅是被动的信息渠道,它们不仅提供了思想的内容,而且也形成着思想的过程。网络如今所做的,似乎就是正在粉碎我集中注意力和思考的能力,我的思想正在按照网络分配信息的方式——迅速流动的粒子流——吸收信息。曾经,我是词汇海洋里自由的冲浪者;现在,我像冲浪板上的人滑行在表面。

网络改变了智力活动的习惯

  我不是唯一这样的人。当我向朋友(他们大多数都从事文字工作)提到我阅读遭遇的麻烦时,他们中许多人也有类似的体验。他们使用网络越多,他们集中注意力于长篇文字上的努力就越艰苦,我追踪的一些博客作者也开始提到这种现象。斯科特·卡普最近就网络媒体写了一篇博客,承认他已不再阅读书籍。“我在大学里主修文学,过去曾是一个贪婪的读书人。到底发生了什么?”他写道。他给自己的问题的回答是:“如果我在网络上的阅读不像过去那么多,那是因为我阅读的方式已经改变了;我寻找到便捷的阅读,但那是因为我思维的方式也改变了么?”

  这些逸闻证明不了太多东西,我们仍然需要长期的神经学和心理学实验,给我们提供网络是如何利用影响力的权威画面。最近出版的由伦敦大学专家主持的上网习惯研究报告表明,我们可能正处于我们阅读和思维方式改变的大海中部。作为这项5年研究计划的组成部分,专家们检查了电脑日志,记录下浏览两个研究网址的访客的行为。这两个网址分别由大英图书馆和不列颠教育协会运营,给访客提供杂志文章、电子书和其他文字信息资源。他们发现,使用这两个网址的人们,表现出 “快速浏览的模式”,从一个资料库跳跃到另外一个资料库,很少返回他们业已访问过的任何资料库。他们从这个网址跳跃到另外一个网址之前,所阅读的文章或书从没有超过一二页。有时候,他们储存下一篇长文,但没有证据显示他们回来过并认真阅读过它。研究报告称:“显然,用户没有以传统的方式进行网上阅读;实际上,有迹象表明,新的‘阅读’模式正在显露,用户草草浏览标题、目录和摘要,努力获取快速的收获。看来似乎是,他们上网是为了避免用传统的方式去阅读。”

  这是一种截然不同的阅读,在它背后则是一种截然不同的思维,甚至是一种新的自我感。图夫兹大学发展心理学教授沃尔夫担心,网络促进的阅读方式,可能正在削弱我们进行深度阅读的能力。她说,当我们在网络上阅读时,我们会变成“信息的简单解码器”,我们在深度阅读中全神贯注地进行丰富的智力思考,都很大程度上烟消云散了。

我们的智力思维会变为人工智力

  沃尔夫解释到,阅读并非人类一种出自本能的技能。我们必须告诉我们的大脑,如何将我们看到的象征符号翻译成我们能够理解的语言,我们在学习和实践中所使用的媒介或其他技术手段,在我们大脑里形成神经中枢线路过程中扮演着重要的角色。实验表明,表意文字的读者,如中国人,在阅读中发展出的智力活动线路,与我们使用字母的书写语言进行阅读形成的智力思维线路迥然不同。

  1882年,尼采购买了一台打印机。他的视力坏了,长期将目光集中在书页上使他筋疲力尽,头痛欲裂。他被迫减少写作,但又担心不久将被迫放弃写作。打字机挽救了他,他掌握打字功能后,能够眼睛闭上写作,只使用他的指尖,词汇再次从他的大脑里流向纸页。但打字机对他的著作产生了微妙的影响。尼采说:“我们的写作装备参与到我们的思想形成中。”在打字机的左右下,德国媒介专家弗雷德里克·基特勒说,尼采的散文经历了“从论战到格言警句、从思想到一语双关的变化”。

  人类的大脑是具有几乎无限的延展性的。乔治·梅森大学神经科学教授奥德斯说,即便成年人的头脑也是非常可塑的,神经细胞经常打破旧的关联形式,形成新的关联形式,使大脑改变其运作的方式。

  由于大脑的可塑性,适应性改变也发生在我们大脑内的生物层面上。互联网对我们的认知功能尤其具有深远的影响。网络给我们送来超链接的内容,闪烁的广告和其他数字廉价物,这些东西在吸引我们的同时,也塑造着我们头脑里对网络的形象的认知。网络的影响并没有终止在电脑屏幕的边缘。当人们的思维调适到网络媒介的繁杂画面时,传统的媒介也必须适应观众新的期望,电视载出滚动的文本新闻和流行的广告,杂志和报纸缩短文章,加上简短的标题或简介。

  在历史上,从来没有哪一种交流体系像今天的互联网一样在我们的生活里扮演如此多的角色。它改变着我们的阅读方式,更在改变着我们的思维。Google 总部犹如互联网时代的高级教会,几乎让我们的生活与它须臾不可分离。公司宣布开发“完美的搜索引擎”,它能够“正确地理解你的意思,并给予你想要的任何东西”。然而,我们从它那里得到的信息片段越多,我们攫取它的馈赠越快,我们的大脑就越来越深地陷入到这种快捷的模式中,失去的不仅是传统的深读,也失去了缜密思维的逻辑基础。

  我深为电影《2001年太空漫游》的场景所困扰,使它显得如此刺激如此怪异的东西,正是电脑对它的思维解体那种充满情感的反应:当一个接一个线路被切断后它的绝望,它如同孩童般的对宇航员的乞求。在2001年的世界,人们已变成机器人一般,大多数人类的特征变成了机器,这就是库布里克在影片里的黑暗寓言:当我们依赖电脑仲裁我们对世界的理解,那就是我们自身的智力变为毫无光泽的人工智力之时。

Is Google Making Us Stupid?

What the Internet is doing to our brains

"Dave, stop. Stop, will you? Stop, Dave. Will you stop, Dave?” So the supercomputer HAL pleads with the implacable astronaut Dave Bowman in a famous and weirdly poignant scene toward the end of Stanley Kubrick’s 2001: A Space Odyssey. Bowman, having nearly been sent to a deep-space death by the malfunctioning machine, is calmly, coldly disconnecting the memory circuits that control its artificial brain. “Dave, my mind is going,” HAL says, forlornly. “I can feel it. I can feel it.”

I can feel it, too. Over the past few years I’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn’t going—so far as I can tell—but it’s changing. I’m not thinking the way I used to think. I can feel it most strongly when I’m reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I’d spend hours strolling through long stretches of prose. That’s rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I’m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle.

I think I know what’s going on. For more than a decade now, I’ve been spending a lot of time online, searching and surfing and sometimes adding to the great databases of the Internet. The Web has been a godsend to me as a writer. Research that once required days in the stacks or periodical rooms of libraries can now be done in minutes. A few Google searches, some quick clicks on hyperlinks, and I’ve got the telltale fact or pithy quote I was after. Even when I’m not working, I’m as likely as not to be foraging in the Web’s info-thickets—reading and writing e-mails, scanning headlines and blog posts, watching videos and listening to podcasts, or just tripping from link to link to link. (Unlike footnotes, to which they’re sometimes likened, hyperlinks don’t merely point to related works; they propel you toward them.)

For me, as for others, the Net is becoming a universal medium, the conduit for most of the information that flows through my eyes and ears and into my mind. The advantages of having immediate access to such an incredibly rich store of information are many, and they’ve been widely described and duly applauded. “The perfect recall of silicon memory,” Wired’s Clive Thompson has written, “can be an enormous boon to thinking.” But that boon comes at a price. As the media theorist Marshall McLuhan pointed out in the 1960s, media are not just passive 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. 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.

I’m not the only one. When I mention my troubles with reading to friends and acquaintances—literary types, most of them—many say they’re having similar experiences. The more they use the Web, the more they have to fight to stay focused on long pieces of writing. Some of the bloggers I follow have also begun mentioning the phenomenon. Scott Karp, who writes a blog about online media, recently confessed that he has stopped reading books altogether. “I was a lit major in college, and used to be [a] voracious book reader,” he wrote. “What happened?” He speculates on the answer: “What if I do all my reading on the web not so much because the way I read has changed, i.e. I’m just seeking convenience, but because the way I THINK has changed?”

Bruce Friedman, who blogs regularly about the use of computers in medicine, also has described how the Internet has altered his mental habits. “I now have almost totally lost the ability to read and absorb a longish article on the web or in print,” he wrote earlier this year. A pathologist who has long been on the faculty of the University of Michigan Medical School, Friedman elaborated on his comment in a telephone conversation with me. His thinking, he said, has taken on a “staccato” quality, reflecting the way he quickly scans short passages of text from many sources online. “I can’t read War and Peace anymore,” he admitted. “I’ve lost the ability to do that. Even a blog post of more than three or four paragraphs is too much to absorb. I skim it.”

Anecdotes alone don’t prove much. And we still await the long-term neurological and psychological experiments that will provide a definitive picture of how Internet use affects cognition. But a recently published study of online research habits, conducted by scholars from University College London, suggests that we may well be in the midst of a sea change in the way we read and think. As part of the five-year research program, the scholars examined computer logs documenting the behavior of visitors to two popular research sites, one operated by the British Library and one by a U.K. educational consortium, that provide access to journal articles, e-books, and other sources of written information. They found that people using the sites exhibited “a form of skimming activity,” hopping from one source to another and rarely returning to any source they’d already visited. They typically read no more than one or two pages of an article or book before they would “bounce” out to another site. Sometimes they’d save a long article, but there’s no evidence that they ever went back and actually read it. The authors of the study report:

    It is clear that users are not reading online in the traditional sense; indeed there are signs that new forms of “reading” are emerging as users “power browse” horizontally through titles, contents pages and abstracts going for quick wins. It almost seems that they go online to avoid reading in the traditional sense.

Thanks to the ubiquity of text on the Internet, not to mention the popularity of text-messaging on cell phones, we may well be reading more today than we did in the 1970s or 1980s, when television was our medium of choice. But it’s a different kind of reading, and behind it lies a different kind of thinking—perhaps even a new sense of the self. “We are not only what we read,” says Maryanne Wolf, a developmental psychologist at Tufts University and the author of Proust and the Squid: The Story and Science of the Reading Brain. “We are how we read.” Wolf worries that the style of reading promoted by the Net, a style that puts “efficiency” and “immediacy” above all else, may be weakening our capacity for the kind of deep reading that emerged when an earlier technology, the printing press, made long and complex works of prose commonplace. When we read online, she says, we tend to become “mere decoders of information.” Our ability to interpret text, to make the rich mental connections that form when we read deeply and without distraction, remains largely disengaged.

Reading, explains Wolf, is not an instinctive skill for human beings. It’s not etched into our genes the way speech is. We have to teach our minds how to translate the symbolic characters we see into the language we understand. And the media or other technologies we use in learning and practicing the craft of reading play an important part in shaping the neural circuits inside our brains. Experiments demonstrate that readers of ideograms, such as the Chinese, develop a mental circuitry for reading that is very different from the circuitry found in those of us whose written language employs an alphabet. The variations extend across many regions of the brain, including those that govern such essential cognitive functions as memory and the interpretation of visual and auditory stimuli. We can expect as well that the circuits woven by our use of the Net will be different from those woven by our reading of books and other printed works.

Sometime in 1882, Friedrich Nietzsche bought a typewriter—a Malling-Hansen Writing Ball, to be precise. His vision was failing, and keeping his eyes focused on a page had become exhausting and painful, often bringing on crushing headaches. He had been forced to curtail his writing, and he feared that he would soon have to give it up. The typewriter rescued him, at least for a time. Once he had mastered touch-typing, he was able to write with his eyes closed, using only the tips of his fingers. Words could once again flow from his mind to the page.

But the machine had a subtler effect on his work. One of Nietzsche’s friends, a composer, noticed a change in the style of his writing. His already terse prose had become even tighter, more telegraphic. “Perhaps you will through this instrument even take to a new idiom,” the friend wrote in a letter, noting that, in his own work, his “‘thoughts’ in music and language often depend on the quality of pen and paper.”

“You are right,” Nietzsche replied, “our writing equipment takes part in the forming of our thoughts.” Under the sway of the machine, writes the German media scholar Friedrich A. Kittler, Nietzsche’s prose “changed from arguments to aphorisms, from thoughts to puns, from rhetoric to telegram style.”

The human brain is almost infinitely malleable. People used to think that our mental meshwork, the dense connections formed among the 100 billion or so neurons inside our skulls, was largely fixed by the time we reached adulthood. But brain researchers have discovered that that’s not the case. James Olds, a professor of neuroscience who directs the Krasnow Institute for Advanced Study at George Mason University, says that even the adult mind “is very plastic.” Nerve cells routinely break old connections and form new ones. “The brain,” according to Olds, “has the ability to reprogram itself on the fly, altering the way it functions.”

As we use what the sociologist Daniel Bell has called our “intellectual technologies”—the tools that extend our mental rather than our physical capacities—we inevitably begin to take on the qualities of those technologies. The mechanical clock, which came into common use in the 14th century, provides a compelling example. In Technics and Civilization, the historian and cultural critic Lewis Mumford described how the clock “disassociated time from human events and helped create the belief in an independent world of mathematically measurable sequences.” The “abstract framework of divided time” became “the point of reference for both action and thought.”

The clock’s methodical ticking helped bring into being the scientific mind and the scientific man. But it also took something away. As the late MIT computer scientist Joseph Weizenbaum observed in his 1976 book, Computer Power and Human Reason: From Judgment to Calculation, the conception of the world that emerged from the widespread use of timekeeping instruments “remains an impoverished version of the older one, for it rests on a rejection of those direct experiences that formed the basis for, and indeed constituted, the old reality.” In deciding when to eat, to work, to sleep, to rise, we stopped listening to our senses and started obeying the clock.

The process of adapting to new intellectual technologies is reflected in the changing metaphors we use to explain ourselves to ourselves. When the mechanical clock arrived, people began thinking of their brains as operating “like clockwork.” Today, in the age of software, we have come to think of them as operating “like computers.” But the changes, neuroscience tells us, go much deeper than metaphor. Thanks to our brain’s plasticity, the adaptation occurs also at a biological level.

The Internet promises to have particularly far-reaching effects on cognition. In a paper published in 1936, the British mathematician Alan Turing proved that a digital computer, which at the time existed only as a theoretical machine, could be programmed to perform the function of any other information-processing device. And that’s what we’re seeing today. The Internet, an immeasurably powerful computing system, is subsuming most of our other intellectual technologies. It’s becoming our map and our clock, our printing press and our typewriter, our calculator and our telephone, and our radio and TV.

When the Net absorbs a medium, that medium is re-created in the Net’s image. It injects the medium’s content with hyperlinks, blinking ads, and other digital gewgaws, and it surrounds the content with the content of all the other media it has absorbed. A new e-mail message, for instance, may announce its arrival as we’re glancing over the latest headlines at a newspaper’s site. The result is to scatter our attention and diffuse our concentration.

The Net’s influence doesn’t end at the edges of a computer screen, either. As people’s minds become attuned to the crazy quilt of Internet media, traditional media have to adapt to the audience’s new expectations. Television programs add text crawls and pop-up ads, and magazines and newspapers shorten their articles, introduce capsule summaries, and crowd their pages with easy-to-browse info-snippets. When, in March of this year, TheNew York Times decided to devote the second and third pages of every edition to article abstracts, its design director, Tom Bodkin, explained that the “shortcuts” would give harried readers a quick “taste” of the day’s news, sparing them the “less efficient” method of actually turning the pages and reading the articles. Old media have little choice but to play by the new-media rules.

Never has a communications system played so many roles in our lives—or exerted such broad influence over our thoughts—as the Internet does today. Yet, for all that’s been written about the Net, there’s been little consideration of how, exactly, it’s reprogramming us. The Net’s intellectual ethic remains obscure.

About the same time that Nietzsche started using his typewriter, an earnest young man named Frederick Winslow Taylor carried a stopwatch into the Midvale Steel plant in Philadelphia and began a historic series of experiments aimed at improving the efficiency of the plant’s machinists. With the approval of Midvale’s owners, he recruited a group of factory hands, set them to work on various metalworking machines, and recorded and timed their every movement as well as the operations of the machines. By breaking down every job into a sequence of small, discrete steps and then testing different ways of performing each one, Taylor created a set of precise instructions—an “algorithm,” we might say today—for how each worker should work. Midvale’s employees grumbled about the strict new regime, claiming that it turned them into little more than automatons, but the factory’s productivity soared.

More than a hundred years after the invention of the steam engine, the Industrial Revolution had at last found its philosophy and its philosopher. Taylor’s tight industrial choreography—his “system,” as he liked to call it—was embraced by manufacturers throughout the country and, in time, around the world. Seeking maximum speed, maximum efficiency, and maximum output, factory owners used time-and-motion studies to organize their work and configure the jobs of their workers. The goal, as Taylor defined it in his celebrated 1911 treatise, The Principles of Scientific Management, was to identify and adopt, for every job, the “one best method” of work and thereby to effect “the gradual substitution of science for rule of thumb throughout the mechanic arts.” Once his system was applied to all acts of manual labor, Taylor assured his followers, it would bring about a restructuring not only of industry but of society, creating a utopia of perfect efficiency. “In the past the man has been first,” he declared; “in the future the system must be first.”

Taylor’s system is still very much with us; it remains the ethic of industrial manufacturing. And now, thanks to the growing power that computer engineers and software coders wield over our intellectual lives, Taylor’s ethic is beginning to govern the realm of the mind as well. The Internet is a machine designed for the efficient and automated collection, transmission, and manipulation of information, and its legions of programmers are intent on finding the “one best method”—the perfect algorithm—to carry out every mental movement of what we’ve come to describe as “knowledge work.”

Google’s headquarters, in Mountain View, California—the Googleplex—is the Internet’s high church, and the religion practiced inside its walls is Taylorism. Google, says its chief executive, Eric Schmidt, is “a company that’s founded around the science of measurement,” and it is striving to “systematize everything” it does. Drawing on the terabytes of behavioral data it collects through its search engine and other sites, it carries out thousands of experiments a day, according to the Harvard Business Review, and it uses the results to refine the algorithms that increasingly control how people find information and extract meaning from it. What Taylor did for the work of the hand, Google is doing for the work of the mind.

The company has declared that its mission is “to organize the world’s information and make it universally accessible and useful.” It seeks to develop “the perfect search engine,” which it defines as something that “understands exactly what you mean and gives you back exactly what you want.” In Google’s view, information is a kind of commodity, a utilitarian resource that can be mined and processed with industrial efficiency. The more pieces of information we can “access” and the faster we can extract their gist, the more productive we become as thinkers.

Where does it end? Sergey Brin and Larry Page, the gifted young men who founded Google while pursuing doctoral degrees in computer science at Stanford, speak frequently of their desire to turn their search engine into an artificial intelligence, a HAL-like machine that might be connected directly to our brains. “The ultimate search engine is something as smart as people—or smarter,” Page said in a speech a few years back. “For us, working on search is a way to work on artificial intelligence.” In a 2004 interview with Newsweek, Brin said, “Certainly if you had all the world’s information directly attached to your brain, or an artificial brain that was smarter than your brain, you’d be better off.” Last year, Page told a convention of scientists that Google is “really trying to build artificial intelligence and to do it on a large scale.”

Such an ambition is a natural one, even an admirable one, for a pair of math whizzes with vast quantities of cash at their disposal and a small army of computer scientists in their employ. A fundamentally scientific enterprise, Google is motivated by a desire to use technology, in Eric Schmidt’s words, “to solve problems that have never been solved before,” and artificial intelligence is the hardest problem out there. Why wouldn’t Brin and Page want to be the ones to crack it?

Still, their easy assumption that we’d all “be better off” if our brains were supplemented, or even replaced, by an artificial intelligence is unsettling. It suggests a belief that intelligence is the output of a mechanical process, a series of discrete steps that can be isolated, measured, and optimized. In Google’s world, the world we enter when we go online, there’s little place for the fuzziness of contemplation. Ambiguity is not an opening for insight but a bug to be fixed. The human brain is just an outdated computer that needs a faster processor and a bigger hard drive.

The idea that our minds should operate as high-speed data-processing machines is not only built into the workings of the Internet, it is the network’s reigning business model as well. The faster we surf across the Web—the more links we click and pages we view—the more opportunities Google and other companies gain to collect information about us and to feed us advertisements. Most of the proprietors of the commercial Internet have a financial stake in collecting the crumbs of data we leave behind as we flit from link to link—the more crumbs, the better. The last thing these companies want is to encourage leisurely reading or slow, concentrated thought. It’s in their economic interest to drive us to distraction.

Maybe I’m just a worrywart. Just as there’s a tendency to glorify technological progress, there’s a countertendency to expect the worst of every new tool or machine. In Plato’s Phaedrus, Socrates bemoaned the development of writing. He feared that, as people came to rely on the written word as a substitute for the knowledge they used to carry inside their heads, they would, in the words of one of the dialogue’s characters, “cease to exercise their memory and become forgetful.” And because they would be able to “receive a quantity of information without proper instruction,” they would “be thought very knowledgeable when they are for the most part quite ignorant.” They would be “filled with the conceit of wisdom instead of real wisdom.” Socrates wasn’t wrong—the new technology did often have the effects he feared—but he was shortsighted. He couldn’t foresee the many ways that writing and reading would serve to spread information, spur fresh ideas, and expand human knowledge (if not wisdom).

The arrival of Gutenberg’s printing press, in the 15th century, set off another round of teeth gnashing. The Italian humanist Hieronimo Squarciafico worried that the easy availability of books would lead to intellectual laziness, making men “less studious” and weakening their minds. Others argued that cheaply printed books and broadsheets would undermine religious authority, demean the work of scholars and scribes, and spread sedition and debauchery. As New York University professor Clay Shirky notes, “Most of the arguments made against the printing press were correct, even prescient.” But, again, the doomsayers were unable to imagine the myriad blessings that the printed word would deliver.

So, yes, you should be skeptical of my skepticism. Perhaps those who dismiss critics of the Internet as Luddites or nostalgists will be proved correct, and from our hyperactive, data-stoked minds will spring a golden age of intellectual discovery and universal wisdom. Then again, the Net isn’t the alphabet, and although it may replace the printing press, it produces something altogether different. The kind of deep reading that a sequence of printed pages promotes is valuable not just for the knowledge we acquire from the author’s words but for the intellectual vibrations those words set off within our own minds. In the quiet spaces opened up by the sustained, undistracted reading of a book, or by any other act of contemplation, for that matter, we make our own associations, draw our own inferences and analogies, foster our own ideas. Deep reading, as Maryanne Wolf argues, is indistinguishable from deep thinking.

If we lose those quiet spaces, or fill them up with “content,” we will sacrifice something important not only in our selves but in our culture. In a recent essay, the playwright Richard Foreman eloquently described what’s at stake:

    I come from a tradition of Western culture, in which the ideal (my ideal) was the complex, dense and “cathedral-like” structure of the highly educated and articulate personality—a man or woman who carried inside themselves a personally constructed and unique version of the entire heritage of the West. [But now] I see within us all (myself included) the replacement of complex inner density with a new kind of self—evolving under the pressure of information overload and the technology of the “instantly available.”

As we are drained of our “inner repertory of dense cultural inheritance,” Foreman concluded, we risk turning into “‘pancake people’—spread wide and thin as we connect with that vast network of information accessed by the mere touch of a button.”

I’m haunted by that scene in 2001. What makes it so poignant, and so weird, is the computer’s emotional response to the disassembly of its mind: its despair as one circuit after another goes dark, its childlike pleading with the astronaut—“I can feel it. I can feel it. I’m afraid”—and its final reversion to what can only be called a state of innocence. HAL’s outpouring of feeling contrasts with the emotionlessness that characterizes the human figures in the film, who go about their business with an almost robotic efficiency. Their thoughts and actions feel scripted, as if they’re following the steps of an algorithm. In the world of 2001, people have become so machinelike that the most human character turns out to be a machine. That’s the essence of Kubrick’s dark prophecy: as we come to rely on computers to mediate our understanding of the world, it is our own intelligence that flattens into artificial intelligence.

  传播学大师马歇尔·麦克卢汉指出,“所有媒体都会对我们产生全方位的影响。它们无所不在,改变着政治、经济、美学、心理、道德、社会……所有的一切都会变化。传媒即按摩。(麦克卢汉曾提出传媒即信息 (message)的经典理论。但他同时也给出传媒即按摩(massage)理论,指出媒体的精神按摩作用。)信息和按摩虽一字之差,却不是纯粹的文字游戏。只有了解了媒体作为环境的影响,才能理解由此引发的社会和文化变革。”

  麦克卢汉虽然没有亲历互联网革命,但他早已预见这场变革将给人类带来的深刻变革。他曾引用苏格拉底的话说:“字母的发明给人们带来忘性,因为这不会花费他们的记忆;人们转而信任外在的字母,而不再动用自己的记忆和思考。”

  “不再像从前一样思考了”

  “Google让我们变傻了吗?”这是著名科技作家尼可拉斯·卡尔抛出的疑问。因为他正为一些发生在自己身上的变化而不安:“我不再像从前一样思考了,尤其是在阅读的时候。从前,全身心地融入一本书或长篇文章是很容易的事情,但是现在已不是这样了。我才看完一两页,注意力就无法再集中,而是愈发焦躁,总要找些别的事去做。我不得不努力地让自己回到书本,这使得阅读成为一个异常艰苦的过程。

  为什么会发生这样的变化?和周围的大部分人一样,卡尔已经习惯于互联网的世界———上网搜索、浏览、也在网上发表作品,做出自己的贡献。对于作家卡尔而言,互联网是再好不过的助手,只要输入几个字母,就能找到他所需要的准确信息,而不用花大把的时间在图书馆检索。即使在不上网的时候,卡尔也习惯在网上看新闻,浏览博客,或者只是从一个链接跳到另一个链接。

  今天的互联网俨然已成为最主要的信息载体,它不仅给世界带来翻天覆地的外在变化,也在以一种潜移默化的方式影响着我们。

  “跳跃式”阅读替代细嚼慢咽

  麦克卢汉在上世纪60年代指出,“媒体不仅只是被动的提供信息渠道,而是在传输资源的同时改变思考的模式”。前所未有的互联网变革更是如此:对于习惯了纸张和书本的人们而言,高速网络让人无法集中注意力,难以深度思考。大脑处理网络信息的方式正如网络本身一样———是对信息流的高速传输,而非细嚼慢咽。

  卡尔就此给出了一个形象的比喻:过去人们习惯在文字的海洋潜水,现在则在奔腾的信息海洋上冲浪!这样的变化显然不止发生在卡尔一个人身上。网络写手斯科特·卡尔普也在博客中提到,曾经酷爱读书的自己完全放弃了阅读印刷作品。“到底发生了什么,我为什么如此倚赖网络,这难道只是因为方便,还是我的思考方式已经变化了。”

  密歇根医学院教授布鲁斯·弗里德曼也在博客上写道,互联网如何改变了他的思维习惯。“现在我已几乎完全丧失了阅读稍长些文章的能力,不管是在网上,还是在纸上。”弗里德曼告诉卡尔,他的思维呈现出一种“片断式”特性,这反映了他上网快速浏览多方短文的习惯。“我再也读不了《战争与和平》了。我失去了这个能力。即便是一篇超过了三四段的博文,也难以吸收。我就只扫一眼。”弗里德曼说。

  人们在互联网上形成的特殊阅读习惯正在得到验证。伦敦大学的学者最近公布了一个有关网络阅读习惯的研究结果。在这个为期5年的项目中,研究者提取了两个学术网站的电脑日志。它们分别由英国图书馆和英国教育协会运作,提供电子期刊、电子书及其他文字信息的在线阅读,一直拥有大批网上读者。

  通过对电脑日志的分析,研究人员发现,两个网站的访客都喜欢“匆匆掠过”,总是从一篇文章“跳跃”到另一篇浏览,而且几乎不会看已经访问过的文章。他们打开一篇文章后,通常读上一两页,然后就转到了别的网站。有时他们会把长篇文章保存下来,但没有证据显示他们会回头再读。

  研究者在报告中结论称:很明显,用户不是在以传统方式进行在线阅读;相反,一种新的方式正在出现:网民们在标题、内容页和摘要间进行着平行式“海量浏览”,为的是很快得到结果。也可以说,人们上网正是为了避开传统意义上的阅读。

  网络让注意力愈发分散

  卡尔和一些学者认为,互联网的迅捷和内容丰富带来的一大副产品是扰乱注意力,让人无法专注于某个事物。心理学研究人员指出,没有人能同时写邮件和打电话,因为大脑无法如此迅速地转移注意力,而长期的“一心二意”导致的后果可能和吸烟一样危险。

  科技作家麦琪·杰克逊在新作《正在到来的黑暗时代》中警告说,当我们的注意力愈发分散,沉溺于走马观花式的认知,我们可能沦为介于人和机器之间的半成品。

  互联网兴起之初,人们总谈论网络给教育带来的变革———过去父母们需要在图书馆苦苦搜寻才能得到的信息,他们的孩子只需轻点一两下鼠标就能得到。但现实并非这样简单,研究显示,青少年访问的网站中,90%都是社交类网站,相比起在网络的知识海洋里畅游,年轻人更喜欢沉溺于网络的社交群落。在《最愚蠢的一代:数码时代如何让美国人变得更蠢》一书中,埃默里大学教授马克·鲍尔雷描绘了网络时代成长起来的年轻人,无法保持足够的注意力来读完一本书,甚至无法用心领会一首诗的含义。

  在信息时代成长的年轻人所拥有的网友数量让他们的父母难以置信,这样的交往方式也更让人担忧。研究人员曾对一位 24岁青年的电邮通讯进行了5年的跟踪研究,他们发现,这位年轻人的网上联系对象超过一千万人,但多数的联系都陷于肤浅的交流,因为在互联网上缺乏现实世界中交往的深度和复杂。

  如果你在社交网站Facebook或MySpace注册,不出几个小时,就能“朋友遍天下”。但是这很难被称之为真正意义上的朋友。互联网的友情能像闪电般诞生,也能同样快地终结。杰克逊由此担心,网络可能危及年轻人在真实社会的社交———他们可能习惯于随心所欲的喜欢或憎恨某个人,由此抛弃现实社会中真实友情所依赖的考验和坚持。

  “效率”和“直接”至上影响阅读

  由于网络承载的前所未有的海量信息,今天的人们显然要比20、30年前读到更多的东西。但这是一种新的阅读方式,或许也代表着新的思维模式和自我认知。

  “我们并非只由阅读的内容影响,”塔夫茨大学的心理学家玛雅妮·沃尔夫说:“我们也被阅读的方式所定义。”她也因此担心,将“效率”和“直接”至上的新阅读风格可能会损害我们进行深度阅读的能力。几百年前的印刷术,让阅读长而深奥的作品成为寻常之事,也让人们能坐下来静心阅读,而今天人们上网阅读时,扮演的角色只是“信息解码器”。人们在专注地深度阅读时所形成的那种理解文本的能力,以及丰富的精神联想力,都被我们抛弃了。

  沃尔夫解释说,阅读并非人类与生俱来的技巧,不像语言那样是人类基因的一部分。人们必须训练自己的大脑,让它将看到的字符翻译成可以理解的语言。而阅读所需的媒体和技术则对大脑的神经系统产生影响。实验证明,使用意表文字的人,如中国人,和使用字母的人在阅读时相比较,神经环路上有明显不同。这样的区别在大脑各个部位都有出现,其中包括掌控核心认知功能的区域。因此,也可以这样推测,在线阅读和读书读报也会产生不同的神经环路。

  回顾历史,从文字的发明到互联网的诞生,人类掌握和传播信息方式的每一个变革,都对我们的思维方式起着潜移默化的作用。1882年,尼采买了一台打字机。当时他的视力正严重下降,如果长时间读书,会感到十分痛苦疲劳。尼采担心会被迫停止写作,但是,打字机救了他。尼采很快熟练掌握了这门技能,闭着眼睛也能打字,让他顺利地把思想变成文字。

  但是,打字机也让尼采作品的风格发生了微妙的变化。一个作曲家朋友写信告诉他,尼采原本很简洁的风格变得更加干练。朋友还说,自己写曲子时,风格经常因纸和笔的特性不同而改变。

  “你说得对,”尼采在回信中说:“我们的写作工具参与了思想的形成。”有人甚至这样形容改用打字机后,尼采文风的变化:“从争辩变成了格言,将思索变为一语双关,从繁复论证变成了简洁的电报式风格”。

  从“像钟表”到“像计算机”

  人们原本认为,我们大脑中复杂的神经联结网在成年时就会定型。但研究人员并不这样认为。

  乔治·曼森大学神经学家詹姆斯·奥尔兹指出,成年人的大脑仍然颇具可塑性,神经细胞经常把原有的联结断开,不断形成新的联结,也因此不断改变着自己。当人们在利用“智能技术”提高我们的大脑能力时,我们也不可避免地采用了这些技术的特性。

  机械钟表在14世纪的广泛普及就是很好的例子。钟表的机械运作帮助人们更好地计算时间,但同样也让我们付出了代价。人们开始根据钟表来决定何时起床、吃饭、工作、睡觉,而不是凭自己的感觉行事。

  这一点也反映在人们经常作的比喻,机械钟表普及时,人们喜欢说大脑“像时钟一样工作”。在今天的信息时代,这个比喻被替换成:大脑“像计算机一样运转”。

  而网络不仅是无数计算机的联结,也融入了人类所有的技术:钟表、计算器、电话、广播和电视。当互联网吸收一个旧媒体时,它的形象就得以在网络的环境里重塑,以新的方式展现。

  不光对于我们的大脑,新媒体同样对传统媒体带来了巨大的冲击,迫使他们适应新媒体制定的规则。为了满足互联网时代观众和读者的需要,电视节目中出现了滚动字幕和弹出广告,报纸和杂志的文章越来越短,并在版面加入更多导读标题,为的是提高阅读的效率。今年3月,《纽约时报》决定将其第2和第3版改为内容精粹,以便忙碌的读者可以更快“品尝”当天的新闻。抛弃原本先在封面看标题,再进内页读新闻的“低效”读报方式。

  信息时代的“泰勒主义”

  在尼采用上新打字机的同一时代,美国费城,一位名叫弗雷德里克·温斯洛·泰勒的年轻人将一块计时秒表带到费城一家炼钢厂,进行劳动时间和工作方法的研究。他把所有工作分成独立的程序,以提高每个程序的工作效率,对此,工人深表不满,认为这将他们变成了机器,但与此同时,钢厂产量得到显著提高。

  这一“系统”今天被称为流水线生产方式。泰勒的发明随后被各地的工厂老板采用,因为它能带来最高效率和最大产量,1911年,泰勒宣称,流水线生产并非局限于工厂的运作,而是将把效率追求放到最重要地位,给社会带来深远影响。“在过去,人是首要的,在未来,系统是首要的。”他说。

  直到今天,流水线生产方式仍在沿用,不止于此,其理念也得以被信息时代继承。互联网的作用是为了有效的信息获取和传播,而其背后的程序员则致力于寻找最好的获得信息的方法。
