I don't normally read books twice. There simply are too many unread books worth reading to return to one I have already read, especially now that I am recording my thoughts about the books I read here on this blog. I did, however, happily agree to re-read Nicholas Carr's book The Shallows when it was proposed by a member of my book club. I was curious to see if I would take away something new from it on a second reading. I suspect not, but my original review by no means covered all of the interesting ideas in this insightful work. You can read my original review by searching on "Shallows" on this blog. What stands out for me on this second reading is what Carr writes about the formation of memory and the relationship that is developing between people and our machines.
In my earlier review, I wrote about Carr's observation that the constant distractions that are presented on the internet are having a detrimental effect on our abilities to transfer working memories into long-term memories. What I did not emphasize, but what is of great significance is the consequences that this has for our abilities to understand the world. A broad and deep understanding of the world is only formulated when a wide variety of experiences are assembled in a coherent set of relationships that generate practical theories about future experience. We need not be conscious of these theories, but they are necessary to navigate the world. For most purposes, our daily, routine experiences are sufficient to allows us to navigate the day, but understanding more subtle relationships among phenomena and their significance requires more careful reflection. It requires the patient, probing, and in depth examination of experience which cannot be accomplished without stable, long-term memories as fodder for thought. If Carr's thesis is true, that the internet impedes the development of stable memories, then it must also be true that it impedes the development of a broad and deep understanding of the world. Over exposure to the internet would have the consequence of making us shallow and superficial.
It is an extremely provocative conclusion, though Carr does not quantify the extent to which the internet has this dulling effect. One could dismiss the concern by asserting that our capacities to understand the world in a deep and meaningful way are only marginally diminished by the internet and that the intellectual capacities that the internet fosters more than make up for the loss; however, our ability to objectively reach this conclusion after long exposure to the internet would be undermined if the thesis is true. Moreover, a simple addiction to the glamour of the internet would also prejudice one's assessment. Having spent countless work hours connected to the internet and countless off-work hours reading, I am inclined argue that I feel significantly more "human" after a three hour stretch of reading as opposed to a three hour stretch of work on the internet and I suspect this is due to the fact that the activities involved in finding meaning in the world are of a much higher intellectual, indeed spiritual, order than the activities involved in the kind of rapid and ever-changing information observation that comes with working on the internet.
A second and more stunning observation that came out of my second reading of The Shallows is Carr's observation that as our cognitive capacities are changed by the internet, they are changed in a manner that makes us more like the digital tools that we are using. Computers access and process information, storing it in a manner that makes it entirely inaccessible until specifically recalled in another processing event. Without the growing store of long-term memories produced by thoughtful reflection, our mental activity becomes more like this information processing, affected only by the immediate inputs of the present cognitive transaction and unaffected by a repository of long-term memories connected in a sophisticated worldview. Certainly our minds must work in the context of some sort of worldview, but in comparison to a pre-internet world view, it is impoverished. What stands out about our mental activity is the immediate information transaction and as we are increasingly communicating (receiving and sending) information on the internet in social networks, we are becoming very sophisticated chips arranged in a network. The only question is, for whose benefit is the network doing its computing?
Certainly, these observations stretch Carr's concerns beyond what one might reasonably have, but there is little doubt that the concerns are significant lead us in the right direction in thinking about the internet and its affect on our selves and society.

The Shallows: What the Internet is Doing to Our Brains / Nicholas Carr -- NY: W.W. Norton, 2010
Nicholas Carr’s The Shallows: What the Internet is Doing to Our Brains is a thoughtful examination of how digital communication technology might inexorably be changing fundamental human mental capacities. His argument begins by noting that our brains are not like computer hardware with a fixed, physical configuration that changes only insofar as it naturally degrades. Instead, brain circuitry is part of a living, changing organism, that is reconfigured by use and disuse. This phenomenon, known as “neuroplasticity,” is well established in the scientific literature.
Following Marshall MacLuhan’s thesis in Understanding Media, Carr argues that the medium that transmits information more profoundly affects our lived experience than the information content that it transmits. As cases in point, Car presents the changes that took place with the advent of typographical spaces between words, the printing press, and finally, the “electric media,” culminating in the internet.
Prior to the printing press, reading and writing was done by a tiny minority of people working as professional scribes. These people became practiced at the careful examination of texts that were written in scriptura continua, i.e., text written without spaces between words. Reading scriptura continua meant that reading was tantamount to solving a puzzle, accomplished by sounding aloud the letters to slowly form the coded message. Consequently, readers became practiced at the careful examination of individual characters and the translation of these symbols into sounds. The assimilation of the meaning was slow and interrupted.
With the advent of spaces between words, words could be quickly recognized as wholes, allowing a text to be read easily, quickly, and silently. According to Carr’s thesis, the shift from reading scriptura continua to reading text with spaces would have caused a significant reconfiguration of the brains of readers, activating and expanding new neurocircuits. It would have reduced certain basic mental capacities while it improved others. As reading became less difficult, readers experienced a state of mind Carr calls “deep reading,” in which readers could become completely engrossed in the content of the text. Reading became a meditative act. This also changed writing in that authors could assume that readers were “attentive” and “deeply engaged both intellectually and emotionally,” thus allowing more complex literary forms.
As the printing press expanded the universe of readers, more and more people developed the mental capacities for deep concentration and sustained attention. Deep reading fostered deeper thinking and the development of more complex mental schemas that foster long-term memory and understanding. With changes to brain circuitry, these capacities could be employed not only when reading, but during other activities.
Of course, all of this changed with the advent of what McLuhan called the “electric media,” which is becoming mature in the internet. This is Carr’s main concern. Unlike the deep reading fostered by books, the internet is fostering short, superficial bursts of reading and viewing. Its designers are seeking to constantly interrupt us and lure us to a new Web site where new content and advertisements can seize our attention briefly before moving us on to the next Web site. We find ourselves scanning information for interesting fragments and multi-tasking because we are lured out of one task before it is complete to begin another. We are not reading in the traditional sense, we are “power browsing.”
Proponents of this new form of information acquisition suggest that the wealth of information now available to us will allow us to make more and various connections between intellectual content and generate novel ideas, but Carr argues that while power browsing may be exhilarating, and may seem to be connecting us quickly to just the information we seek, the gains are ephemeral. Citing research on working memory and long-term memory, he notes that power browsing does not allow us the time to fix the information presented to our working memory in long-term memory. It is out of long-term memory that we construct our conceptual schema that allows us a deep understanding of the world. As a result, power browsing not only diminishes our capacity for sustained concentration, it undermines the sort of intelligence that has been promoted by the literary mind.
Carr's thesis is provocative, but he is at pains not to overstate it. Throughout The Shallows, Carr reminds us that the internet is not only impoverishing specific intellectual powers, it is improving others. For example, experienced Web surfers are able to quickly identify on a Web page the item or fragment of information that they seek. This ability to pick out what is critical in a cluttered visual field is a "bottom-up" brain mechanism that transfers to other contexts just as the "top-down" ability for sustained concentration translates across contexts. Nonetheless, Carr’s sympathies are clearly with deep reading.
Certainly, proponents of the internet will down play what is lost with the decline of deep reading and play up what is gained with the ascent of power browsing, but Carr’s warning is hard to ignore. Neuroplasticity makes our changing reading habits much more significant than one might originally think, and I expect that many people who already have developed the habit of deep reading will recognize the cognitive changes that Carr observes coming from working with electronic media, particularly the internet. Perhaps it is because the assessment of the value of this change is coming from a deep reader, but it certainly seems that something very valuable is being replaced with something terribly, terribly shallow.
It is also interesting to consider Carr's claims in the context of Jaron Lanier's recent book, You Are Not a Gadget (reviewed in this blog). Lanier warns that the internet is increasingly dehumanizing us by reducing us to fragmented content contributors to a vast network of computers. He warns that our very personhood is being reduced to what can be indexed in social networking metadata and presented by Web search engines. "You are not a gadget" is Lanier's rallying cry to resist this dehumanization. Unfortunately, if Carr is right about the restructuring of our brains, one might argue that the internet is, indeed, slowly, but inexorably, turning us into gadgets.
