Yesterday, the NPD Group released the results of a survey of iPad owners. The most intriguing finding was that “20 percent of users’ time with the iPad was spent with it in bed.” One has to wonder what other sorts of activities are being displaced by the nocturnal stroking of the iPad’s highly responsive screen.

A couple of weeks ago, I had the pleasure of doing an interview with the BBC World Service’s excellent show Digital Planet. One thing we discussed was the way software tools, by automating certain mental chores, may in subtle ways weaken our ability to learn. We talked, in particular, about how the reliance on GPS systems may weaken our ability to build mental maps of space, as well as about a fascinating Dutch study that showed that user-friendly software can lead to intellectual laziness.

The brief interview, which you can hear here, inspired a BBC News article yesterday that bore the headline “How good software makes us stupid.”

And then, today, that BBC News article turned into a Daily Telegraph piece with this headline:

I can’t wait to see the headline in the News of the World.

Wired magazine cover story, August 2005: “We Are the Web”

Wired magazine cover story, September 2010: “The Web Is Dead”

Unavoidable conclusion: “We Are Dead”

A couple of weeks ago, MIT’s Nicholas Negroponte, chairman of the One Laptop per Child initiative, foretold the death of the printed book. Today, he foretells the death of book-reading: “I love the iPad, but my ability to read any long-form narrative has more or less disappeared, as I am constantly tempted to check e-mail, look up words or click through.”

Five neuroscientists get into a raft. That might be the start of a mildly funny joke, but in this case it’s the premise of an article by Matt Richtel in today’s New York Times, the latest installment in the paper’s series on “computers and the brain.” Richtel accompanies the scientists as they float down a remote stretch of the San Juan River in Utah, beyond the reach of cell towers and wi-fi signals. The impetus for the trip was, Richtel reports, “to understand how heavy use of digital devices and other technology changes how we think and behave, and how a retreat into nature might reverse those effects.”

Two of the neuroscientists start the trip believing that the Net and related technologies can undermine people’s ability to pay attention, impeding deep thinking and even causing psychological problems. The other three are more sanguine about the effects of the technologies. To see what transpires, you’ll need to read the article.

The piece raises one particular idea that I found to be intriguing, and troubling. As the trip proceeds, the scientists begin to wonder “whether attention and focus can take a hit when people merely anticipate the arrival of more digital stimulation”:

“The expectation of e-mail seems to be taking up our working memory,” [Johns Hopkins professor Steven] Yantis says.

Working memory is a precious resource in the brain. The scientists hypothesize that a fraction of brain power is tied up in anticipating e-mail and other new information — and that they might be able to prove it using imaging.

“To the extent you have less working memory, you have less space for storing and integrating ideas and therefore less to do the reasoning you need to do,” says [University of Illinois professor Art] Kramer, floating nearby.

In The Shallows, I review a series of studies that indicate that the fast-paced delivery of messages and other information online overloads working memory, leading to a state of perpetual distractedness. In my research I didn’t come across the idea that the mere anticipation of receiving a fresh burst of information would also add to our cognitive load. But it makes sense. Research shows, for example, that office workers tend to glance at their email inbox 30 or more times an hour, which seems to me to be pretty clear evidence that even when we’re not reading messages we’re thinking about receiving messages – not just emails, but texts, Facebook updates, tweets, and so on.

This would also help explain why the Net continues to distract us even when we’re not online. Part of our mind is still thinking about that new message that might have just arrived in our inbox. What makes that hypothetical unread message particularly distracting is that it could actually be important. You won’t know until you’ve read it. Admit it: The suspense is killing you.

In an interview published today in the Wall Street Journal, Google CEO Eric Schmidt lays out the next stage in his company’s ambitious plan to replace human agency with automated data processing, freeing us all from the nuisance of thinking:

“We’re trying to figure out what the future of search is,” Mr. Schmidt acknowledges. “I mean that in a positive way. We’re still happy to be in search, believe me. But one idea is that more and more searches are done on your behalf without you needing to type.”

“I actually think most people don’t want Google to answer their questions,” he elaborates. “They want Google to tell them what they should be doing next.”

Let’s say you’re walking down the street. Because of the info Google has collected about you, “we know roughly who you are, roughly what you care about, roughly who your friends are.” Google also knows, to within a foot, where you are. Mr. Schmidt leaves it to a listener to imagine the possibilities: If you need milk and there’s a place nearby to get milk, Google will remind you to get milk. It will tell you a store ahead has a collection of horse-racing posters, that a 19th-century murder you’ve been reading about took place on the next block.

Says Mr. Schmidt, a generation of powerful handheld devices is just around the corner that will be adept at surprising you with information that you didn’t know you wanted to know. “The thing that makes newspapers so fundamentally fascinating—that serendipity—can be calculated now. We can actually produce it electronically,” Mr. Schmidt says.

Awesome! I’ve always thought that the worst thing about serendipity was its randomness.

I hope Google will also be able to tell me the best candidate to vote for in elections. I find that such a burden.

The Wall Street Journal has been running an important series about the collection and exploitation of personal information on the Net. As part of that series, it is featuring a debate today between me and the Cato Institute’s Jim Harper about online privacy – more particularly, the tradeoff between privacy and personalization.

My essay begins like this:

In a 1963 Supreme Court opinion, Chief Justice Earl Warren observed that “the fantastic advances in the field of electronic communication constitute a great danger to the privacy of the individual.” The advances have only accelerated since then, along with the dangers. Today, as companies strive to personalize the services and advertisements they provide over the Internet, the surreptitious collection of personal information is rampant. The very idea of privacy is under threat.

Most of us view personalization and privacy as desirable things, and we understand that enjoying more of one means giving up some of the other. To have goods, services and promotions tailored to our personal circumstances and desires, we need to divulge information about ourselves to corporations, governments or other outsiders.

This tradeoff has always been part of our lives as consumers and citizens. But now, thanks to the Net, we’re losing our ability to understand and control those tradeoffs — to choose, consciously and with awareness of the consequences, what information about ourselves we disclose and what we don’t. Incredibly detailed data about our lives is being harvested from online databases without our awareness, much less our approval …

And here’s the start of Harper’s piece:

If you surf the web, congratulations! You are part of the information economy. Data gleaned from your communications and transactions grease the gears of modern commerce. Not everyone is celebrating, of course. Many people are concerned and dismayed—even shocked—when they learn that “their” data are fuel for the World Wide Web.

Who is gathering the information? What are they doing with it? How might this harm me? How do I stop it?

These are all good questions. But rather than indulging the natural reaction to say “stop,” people should get smart and learn how to control personal information. There are plenty of options and tools people can use to protect privacy—and a certain obligation to use them. Data about you are not “yours” if you don’t do anything to control them. Meanwhile, learning about the information economy can make clear its many benefits …
