With National Database, India Tries to Reach the Poor - NYTimes.com - 0 views

  • Privacy advocates contend that the government will use it to track citizens, a serious concern in a country where the government carries out extensive wiretapping and surveillance to track potential terrorists.
  • The database has been designed to contain as little information as possible — only a name, date of birth, sex and address. When anyone tries to confirm a person’s identity using the number, the database will supply only a yes-or-no answer.
  • Because Aadhaar will be linked instantly with a bank account, some social activists suspect that the government is seeking to replace its current system of in-kind benefits — like distributing grain and creating state-supported jobs — with direct cash transfers. Many on the left oppose such a shift because they think handing out cash from the public till would create a backlash and undercut support for poverty programs.

Project Classroom: Transforming Our Schools for the Future - Rebecca J. Rosen - Technol... - 0 views

  • Games are integral in human society, from ancient times to the present. Games are based on strategy and on challenge. If you do well at a game, your reward isn't "recess" or a "time out"; it's a greater challenge. When you beat a tough opponent, you seek out a tougher one. That is learning. Being able to harness the energy of games is one of our best learning tools, as any good parent knows, from patty-cake to Simon Says to musical chairs to chess or go. You can advance physical, mental, linguistic, and intellectual progress through games where the testing isn't after the fact but is intrinsic to and embedded in the very structure of play.
  • I recently was able to see a demonstration of a fantastic online algebra game, for example, that not only challenges learning, but where every problem is a test, in the sense that, if you don't solve the problem, the system generates a new problem that goes a little backward to some more basic principles, and then, when you succeed, it generates a more advanced problem and so forth. The results are amazing, because the test isn't at the end of the year, it is in everything you do, as you do it, getting not just harder and harder but more and more interesting. We know that boredom -- for the most gifted students and also for the lowest academic achievers -- is the biggest inhibitor of learning there is.
  • if the classroom experience is inferior to an online educational program, get rid of it!   If you respect and honor the fact that humans love collective experiences where we cheer, fear, laugh, or learn together -- we pay to go to sports, movies, comedy clubs, concerts, and lectures -- then you can begin to rethink school as a collective event and maximize what is added by a group experiencing together.

How Animal Welfare Leads to Better Meat: A Lesson From Spain - Daisy Freund - Life - Th... - 0 views

  • research being conducted in Australia and New Zealand is showing that when stress is minimized in animals, the meat has a lower pH and is consistently more delicate than in animals that experience stress during transport, handling, and slaughter.
  • the U.N. Food and Agriculture Organization talks extensively about PSE in its "Guidelines for Humane Handling, Transport and Slaughter of Livestock." When the animals are subjected to manhandling, fighting in the pens, and bad stunning techniques, the fright and stress causes a rapid breakdown of muscle glycogen. This lightens the color of the meat and turns it acidic and tasteless, making it difficult to sell, so it is usually discarded
  • most meat today is ground beyond recognition and consumers can't taste the difference, so the cost of creating stress-free environments for animals doesn't pay off.
  • ...1 more annotation...
  • fear experienced during slaughter significantly elevates meat's levels of stress hormones—adrenaline, cortisol, and other steroids. Studies on human consumption of artificial growth hormones, which are believed by many to affect our reproductive systems and other bodily processes, have already resulted in policy changes in many countries, including those that make up the E.U. Attention is now turning to these naturally occurring fear-induced hormones as scientists worry that their consumption causes similar problems.

Corporate Interests Threaten Children's Welfare - NYTimes.com - 0 views

  • A clash between these two newly created legal entities — children and corporations — was, perhaps, inevitable. Century-of-the-child reformers sought to resolve conflicts in favor of children. But over the last 30 years there has been a dramatic reversal: corporate interests now prevail. Deregulation, privatization, weak enforcement of existing regulations and legal and political resistance to new regulations have eroded our ability, as a society, to protect children.
  • As Nelson Mandela has said, “there can be no keener revelation of a society’s soul than the way in which it treats its children.” By that measure, our current failure to provide stronger protection of children in the face of corporate-caused harm reveals a sickness in our societal soul.

A Theory of Everyting (Sort of) - NYTimes.com - 0 views

  • Across the world, a lot of middle- and lower-middle-class people now feel that the “future” is out of their grasp, and they are letting their leaders know it.
  • the world has gone from connected to hyper-connected. This is the single most important trend in the world today.
  • And it is a critical reason why, to get into the middle class now, you have to study harder, work smarter and adapt quicker than ever before. All this technology and globalization are eliminating more and more “routine” work — the sort of work that once sustained a lot of middle-class lifestyles.
  • ...4 more annotations...
  • It used to be that only cheap foreign manual labor was easily available; now cheap foreign genius is easily available. This explains why corporations are getting richer and middle-skilled workers poorer. Good jobs do exist, but they require more education or technical skills. Unemployment today still remains relatively low for people with college degrees. But to get one of those degrees and to leverage it for a good job requires everyone to raise their game. It’s hard.
  • At little Grinnell College in rural Iowa, with 1,600 students, “nearly one of every 10 applicants being considered for the class of 2015 is from China.” The article noted that dozens of other American colleges and universities are seeing a similar surge as well. And the article added this fact: Half the “applicants from China this year have perfect scores of 800 on the math portion of the SAT.”
  • This globalization/I.T. revolution is also “super-empowering” individuals, enabling them to challenge hierarchies and traditional authority figures — from business to science to government. It is also enabling the creation of powerful minorities and making governing harder and minority rule easier than ever.
  • So let’s review: We are increasingly taking easy credit, routine work and government jobs and entitlements away from the middle class — at a time when it takes more skill to get and hold a decent job, at a time when citizens have more access to media to organize, protest and challenge authority and at a time when this same merger of globalization and I.T. is creating huge wages for people with global skills (or for those who learn to game the system and get access to money, monopolies or government contracts by being close to those in power) — thus widening income gaps and fueling resentments even more.

Can Jeremy Grantham Profit From Ecological Mayhem? - NYTimes.com - 0 views

  • Energy “will give us serious and sustained problems” over the next 50 years as we make the transition from hydrocarbons — oil, coal, gas — to solar, wind, nuclear and other sources, but we’ll muddle through to a solution to Peak Oil and related challenges. Peak Everything Else will prove more intractable for humanity. Metals, for instance, “are entropy at work . . . from wonderful metal ores to scattered waste,” and scarcity and higher prices “will slowly increase forever,” but if we scrimp and recycle, we can make do for another century before tight constraint kicks in.
  • Agriculture is more worrisome. Local water shortages will cause “persistent irritation” — wars, famines. Of the three essential macro nutrient fertilizers, nitrogen is relatively plentiful and recoverable, but we’re running out of potassium and phosphorus, finite mined resources that are “necessary for all life.” Canada has large reserves of potash (the source of potassium), which is good news for Americans, but 50 to 75 percent of the known reserves of phosphate (the source of phosphorus) are located in Morocco and the western Sahara. Assuming a 2 percent annual increase in phosphorus consumption, Grantham believes the rest of the world’s reserves won’t last more than 50 years, so he expects “gamesmanship” from the phosphate-rich.
  • he rates soil erosion as the biggest threat of all. The world’s population could reach 10 billion within half a century — perhaps twice as many human beings as the planet’s overtaxed resources can sustainably support, perhaps six times too many.

  • most economists see global trade as a win-win proposition, but resource limitation turns it into a win-lose, zero-sum contest. “The faster China grows, the higher grain prices go, the more people in China or India who upgrade to meat, the higher the tendency for Africa to starve,” he said.
  • Grantham argues that the late-18th-century doomsayer Thomas Malthus pretty much got it right but just had the bad timing to make his predictions about unsustainable population growth on the eve of the hydrocarbon-fueled Industrial Revolution, which “partially removed the barriers to rapid population growth, wealth and scientific progress.” That put off the inevitable for a couple of centuries, but now, ready or not, the age of cheap hydrocarbons is ending. Grantham’s July letter concludes: “We humans have the brains and the means to reach real planetary sustainability. The problem is with us and our focus on short-term growth and profits, which is likely to cause suffering on a vast scale. With foresight and thoughtful planning, this suffering is completely avoidable.”
  • “E.D.F. is educating people that dealing with climate change will be good for the economy and job creation. One of Jeremy’s insights is that we can make headway on the market side because higher commodity prices will enforce greater efficiency.”
  • When he reminds us that modern capitalism isn’t equipped to handle long-range problems or tragedies of the commons (situations like overfishing or global warming, in which acting rationally in your own self-interest only deepens the harm to all), when he urges us to outgrow our touching faith in the efficiency of markets and boundless human ingenuity, and especially when he says that a wise investor can prosper in the coming hard times, his bad news and its silver lining come with a built-in answer to the skeptical question that Americans traditionally pose to egghead Cassandras: If you’re so smart, how come you’re not rich?
  • Grantham believes that the best approach may be to recast global warming, which depresses crop yields and worsens soil erosion, as a factor contributing to resource depletion. “People are naturally much more responsive to finite resources than they are to climate change,” he said. “Global warming is bad news. Finite resources is investment advice.”
  • “Americans are just about the worst at dealing with long-term problems, down there with Uzbekistan,” he said, “but they respond to a market signal better than almost anyone. They roll the dice bigger and quicker than most.”
  • Grantham, the public face of a company that manages more than $100 billion in assets, the very embodiment of a high-finance insider in blue blazer and yellow tie, has serious doubts about capitalism’s ability to address the biggest problems facing humanity.
  • Grantham says that corporations respond well to this message because they are “persuaded by data,” but American public opinion is harder to move, and contemporary American political culture is practically dataproof. “The politicians are the worst,” he said. “An Indian economist once said to me, ‘We have 28 political parties, and they all think climate change is important.’ ” Whatever the precise number of parties in India, and it depends on how you count, his point was that the U.S. has just two that matter, one that dismisses global warming as a hoax and one that now avoids the subject.
  • Grantham, who says that “this time it’s different are the four most dangerous words in the English language,” has become a connoisseur of bubbles. His historical study of more than 300 of them shows the same pattern occurring again and again. A bump in sales or some other impressive development causes people to get excited. When they do, the price of that asset class — South Sea company shares, dot-coms — goes up, and human nature and the financial industry conspire to push it higher. People want to hear good news; they tend to be bad with numbers and uncertainty, and to assume that present conditions will persist. In the financial industry, the imperative to minimize career risk produces herd behavior.
  • So it’s news when Grantham, who has built his career on the conviction that peaks and troughs will even out as prices inevitably revert to their historical mean, says that this time it really is different, and not in a good way. In his April letter, “Time to Wake Up: Days of Abundant Resources and Falling Prices Are Over Forever,” he argued that “we are in the midst of one of the giant inflection points in economic history.” The market is “sending us the Mother of all price signals,” warning us that “if we maintain our desperate focus on growth, we will run out of everything and crash.”
  • here’s the short version: “The prices of all important commodities except oil declined for 100 years until 2002, by an average of 70 percent. From 2002 until now, this entire decline was erased by a bigger price surge than occurred during World War II. Statistically, most commodities are now so far away from their former downward trend that it makes it very probable that the old trend has changed — that there is in fact a Paradigm Shift — perhaps the most important economic event since the Industrial Revolution.”
  • When prices go up and stay up, it’s not a bubble. Prices may always revert to the mean, but the mean can change; that’s a paradigm shift. As Grantham tells it, oil went first. For a century it steadily returned to about $16 a barrel in today’s currency, then in 1974 the mean shifted to about $35, and Grantham believes it has recently doubled again. Metals and nearly everything else — coal, corn, palm oil, soybeans, sugar, cotton — appear to be following suit. “From now on, price pressure and shortages of resources will be a permanent feature of our lives,” he argues. “The world is using up its natural resources at an alarming rate, and this has caused a permanent shift in their value. We all need to adjust our behavior to this new environment. It would help if we did it quickly.”
  • Grantham is taking the Malthusian side in an ongoing debate about growth and commodity prices­. The argument often circles back to the bet made in 1980 between the biologist Paul Ehrlich, who foretold catastrophic scarcity caused by overpopulation, and the economist Julian Simon, who argued that any short-term increase in resource prices caused by population growth will stimulate inventors and entrepreneurs to find new ways to exploit those resources, lowering prices in the long run. The two men picked five commodities and wagered on whether their prices, taken as an indicator of scarcity, would be higher or lower in 1990. Simon won, 5-0, even though the world’s population grew by 800 million during that decade. Malthusians have been trying to live down that defeat ever since, but, as Grantham points out in his July letter, if we extend the original bet past its arbitrary 10-year limit to the present day, Ehrlich wins the five-commodity bet 4-1, and he wins big if the bet is further extended to all important commodities.
  • He’s an impassioned environmentalist not only for the usual reasons but also because he believes humanity’s vexed relationship with the planet is the great economic story of our time. “This commodities thing may turn out to be the most interesting call of my career,” he told me. “I have no doubt we’re going to have a bad hundred years. We have the resources to gracefully handle the transition, but we won’t. We apparently can’t.”
  • “Whether the stable population will be 1.5 billion or 5 billion,” he said to me, “the question is: How do we get there?”

Waiting for a Landslide - NYTimes.com - 0 views

  • realignments in American politics are usually punctuated by transformative elections, in which the old order suddenly gives way and a new majority emerges in its place.
  • This “realignment theory” was embraced by many scholars because it fit the historical record so well. Every 30 to 40 years, it seemed, the American political order had decisively turned over: in 1800, when Thomas Jefferson’s Democratic-Republicans trounced John Adams’s Federalists; in 1828, when the Democratic-Republicans split into the Democrats and the Whigs; and then on down through Abraham Lincoln’s 1860 victory, William McKinley’s 1896 consolidation of a Republican majority, and the emergence of Franklin Roosevelt’s New Deal coalition.
  • One reason American policy-making has become “less stable, less effective, and less predictable” — in the words of the downgrade that Standard & Poor’s handed to the United States on Friday night — is the enduring influence of V. O. Key’s theory, and the seductive dream of realignment that it conjured up.

Do Political Experts Know What They're Talking About? | Wired Science | Wired... - 0 views

  • I often joke that every cable news show should be forced to display a disclaimer, streaming in a loop at the bottom of the screen. The disclaimer would read: “These talking heads have been scientifically proven to not know what they are talking about. Their blather is for entertainment purposes only.” The viewer would then be referred to Tetlock’s most famous research project, which began in 1984.
  • He picked a few hundred political experts – people who made their living “commenting or offering advice on political and economic trends” – and began asking them to make predictions about future events. He had a long list of pertinent questions. Would George Bush be re-elected? Would there be a peaceful end to apartheid in South Africa? Would Quebec secede from Canada? Would the dot-com bubble burst? In each case, the pundits were asked to rate the probability of several possible outcomes. Tetlock then interrogated the pundits about their thought process, so that he could better understand how they made up their minds.
  • Most of Tetlock’s questions had three possible answers; the pundits, on average, selected the right answer less than 33 percent of the time. In other words, a dart-throwing chimp would have beaten the vast majority of professionals. These results are summarized in his excellent Expert Political Judgment.
  • ...5 more annotations...
  • Some experts displayed a top-down style of reasoning: politics as a deductive art. They started with a big-idea premise about human nature, society, or economics and applied it to the specifics of the case. They tended to reach more confident conclusions about the future. And the positions they reached were easier to classify ideologically: that is the Keynesian prediction and that is the free-market fundamentalist prediction and that is the worst-case environmentalist prediction and that is the best case technology-driven growth prediction etc. Other experts displayed a bottom-up style of reasoning: politics as a much messier inductive art. They reached less confident conclusions and they are more likely to draw on a seemingly contradictory mix of ideas in reaching those conclusions (sometimes from the left, sometimes from the right). We called the big-idea experts “hedgehogs” (they know one big thing) and the more eclectic experts “foxes” (they know many, not so big things).
  • The most consistent predictor of consistently more accurate forecasts was “style of reasoning”: experts with the more eclectic, self-critical, and modest cognitive styles tended to outperform the big-idea people (foxes tended to outperform hedgehogs).
  • Lehrer: Can non-experts do anything to encourage a more effective punditocracy?
  • Tetlock: Yes, non-experts can encourage more accountability in the punditocracy. Pundits are remarkably skillful at appearing to go out on a limb in their claims about the future, without actually going out on one. For instance, they often “predict” continued instability and turmoil in the Middle East (predicting the present) but they virtually never get around to telling you exactly what would have to happen to disconfirm their expectations. They are essentially impossible to pin down. If pundits felt that their public credibility hinged on participating in level playing field forecasting exercises in which they must pit their wits against an extremely difficult-to-predict world, I suspect they would be learn, quite quickly, to be more flexible and foxlike in their policy pronouncements.

The Columbian Exchange and the Real Story of Globalization - WSJ.com - 0 views

  • A growing number of scholars believe that the ecological transformation set off by Columbus's voyages was one of the establishing events of the modern world. Why did Europe rise to predominance? Why did China, once the richest, most advanced society on earth, fall to its knees? Why did chattel slavery take hold in the Americas? Why was it the United Kingdom that launched the Industrial Revolution? All of these questions are tied in crucial ways to the Columbian Exchange.

  • ...9 more annotations...
  • Sailors balanced out the weight by leaving behind their ships' ballast: stones, gravel and soil. They swapped English dirt for Virginia tobacco. That dirt very likely contained the common nightcrawler and the red marsh worm. So, almost certainly, did the rootballs of plants that the colonists imported.
  • In worm-free woodlands, leaves pile up in drifts on the forest floor. Trees and shrubs in wormless places depend on litter for food. When earthworms arrive, they quickly consume the leaf litter, packing the nutrients deep in the soil in the form of castings (worm excrement). Suddenly, the plants can no longer feed themselves; their fine, surface-level root systems are in the wrong place. Wild sarsaparilla, wild oats, Solomon's seal and a host of understory plants die off; grass-like species such as Pennsylvania sedge take over. Sugar maples almost stop growing, and ash seedlings start to thrive.
  • Transported in the bodies of sailors, malaria may have crossed the ocean as early as Columbus's second voyage. Yellow fever, malaria's frequent companion, soon followed. By the 17th century, the zone where these diseases held sway—coastal areas roughly from Washington, D.C., to the Brazil-Ecuador border—was dangerous territory for European migrants, many of whom died within months of arrival
  • Initially, American planters preferred to pay to import European laborers—they spoke the same language and knew European farming methods. They also cost less than slaves bought from Africa, but they were far less hardy and thus a riskier investment. In purely economic terms, the historian Philip Curtin has calculated, the diseases of the Columbian Exchange made the enslaved worker "preferable at anything up to three times the price of the European."
  • At the time, England and Scotland shared a monarch but remained separate nations. England, the bigger partner, had been pushing a complete merger for decades. Scots had resisted, fearing a London-dominated economy, but now England promised to reimburse investors in the failed Panama project as part of a union agreement. As Mr. McNeill wrote, "Thus Great Britain was born, with assistance from the fevers of Panama."
  • Eighteenth-century farmers who planted potatoes reaped about four times as much dry food matter as they did from wheat or barley. Hunger was then a familiar presence in Europe. France had 40 nationwide food calamities between 1500 and 1800, more than one every decade, according to the French historian Fernand Braudel. England had still more. The continent simply could not sustain itself. The potato allowed most of Europe—a 2,000-mile band between Ireland and the Ukraine—to feed itself. (Corn, another American crop, played a similar role in Italy and Romania.) Political stability, higher incomes and a population boom were the result. Imported from Peru, the potato became the fuel for the rise of Europe.
  • The sweet potato played a similar role in China. Introduced (along with corn) from South America via the Pacific silver trade in the 1590s, it suddenly provided a way for Chinese farmers to cultivate upland areas that had been unusable for rice paddies. The nutritious new crop encouraged the fertility boom of the Qing dynasty, but the experiment soon went badly wrong. Because Chinese farmers had never cultivated their dry uplands, they made beginners' mistakes. An increase in erosion led to extraordinary levels of flooding, which in turn fed popular unrest and destabilized the government. The new crops that had helped to strengthen Europe were a key factor in weakening China.
  • European ships accidentally imported the fungus-like organism, native to Peru, that causes the potato disease known as late blight. First appearing in Flanders in June 1845, it was carried by winds to potato farms around Paris in August. Weeks later it wiped out fields in the Netherlands, Germany, Denmark and England. Blight appeared in Ireland on Sept. 13.

We Can't Teach Students to Love Reading - The Chronicle Review - The Chronicle of Highe... - 0 views

  • While virtually anyone who wants to do so can train his or her brain to the habits of long-form reading, in any given culture, few people will want to. And that's to be expected. Serious "deep attention" reading has always been and will always be a minority pursuit, a fact that has been obscured in the past half-century
  • From 1945 to 2000, or thereabouts, far more people than ever before in human history were expected to read, understand, appreciate, and even enjoy books. In 2005, Wendy Griswold, Terry McDonnell, and Nathan Wright, sociologists from Northwestern University, published a paper concluding that while there was a period in which extraordinarily many Americans practiced long-form reading, whether they liked it or not, that period was indeed extraordinary and not sustainable in the long run. "We are now seeing such reading return to its former social base: a self-perpetuating minority that we shall call the reading class."
  • much of the anxiety about American reading habits, and those in other developed nations to a lesser degree, arises from frustration at not being able to sustain a permanent expansion of "the reading class" beyond what may be its natural limits.
  • ...16 more annotations...
  • The extreme reader, to coin a phrase, is a rare bird indeed. ("I have done what people do, my life makes a reasonable showing," Lynne Sharon Schwartz writes. "Can I go back to my books now?") Such people are born, not made, I think; or mostly born and only a little made.
  • It is more common to come across the person who has known the joys of reading but who can be distracted from them. But even those folks are a small percentage of the population.
  • American universities are largely populated by people who don't fit either of these categories—often really smart people for whom the prospect of several hours attending to words on pages (pages of a single text) is not attractive.
  • Steven Pinker once said that "Children are wired for sound, but print is an optional accessory that must be painstakingly bolted on." The key here is "painstakingly": There can be many pains, in multiple senses of the word, for all parties involved, and it cannot be surprising that many of the recipients of the bolting aren't overly appreciative, and that even those who are appreciative don't find the procedure notably pleasant.
  • the printing press ushered in an age of information overload. In the 17th century, one French scholar cried out, "We have reason to fear that the multitude of books which grows every day in a prodigious fashion will make the following centuries fall into a state as barbarous as that of the centuries that followed the fall of the Roman Empire." Such will be our fate "unless we try to prevent this danger by separating those books which we must throw out or leave in oblivion from those which one should save and within the latter between what is useful and what is not."
  • Rarely has education been about teaching children, adolescents, or young adults how to read lengthy and complicated texts with sustained, deep, appreciative attention—at least, not since the invention of the printing press. When books were scarce, the situation was different:
  • Bacon tells such worried folks that they can't read them all, and so should develop strategies of discernment that enable them to make wise decisions about how to invest their time. I think Bacon would have applauded Clay Shirky's comment that we suffer not from "information overload" but from "filter failure."
  • especially noteworthy is Bacon's acknowledgment that there is a place for what Katherine Hayles would call "hyper attention" as well as "deep attention." Some books don't need to be read with patience and care; at times it's OK, even necessary, to skim (merely to "taste" rather than to ruminate). And as Shreeharsh Kelkar, a graduate student at the Massachusetts Institute of Technology, has pointed out, "To be successful today, it not only becomes necessary to skim, but it becomes essential to skim well."
  • Except in those cultures in which books have been scarce, like Augustine's Roman North Africa, the aims of education have often focused, though rarely explicitly so, on the skills of skimming well. Peter Norvig says: "When the only information on the topic is a handful of essays or books, the best strategy is to read these works with total concentration. But when you have access to thousands of articles, blogs, videos, and people with expertise on the topic, a good strategy is to skim first to get an overview. Skimming and concentrating can and should coexist."
  • education, especially in its "liberal arts" embodiments, has been devoted to providing students with navigational tools—with enough knowledge to find their way through situations that they might confront later in life.
  • All this is to say that the idea that many teachers hold today, that one of the purposes of education is to teach students to love reading—or at least to appreciate and enjoy whole books—is largely alien to the history of education.
  • Rose's book is largely a celebration of autodidacticism, of people whose reading—and especially the reading of classic texts, from Homer to Dante to Shakespeare to the great Romantic poets—wasn't imposed on them by anyone, and who often had to overcome significant social obstacles in order to read. "The autodidacts' mission statement," Rose writes, was "to be more than passive consumers of literature, to be active thinkers and writers. Those who proclaimed that 'knowledge is power' meant that the only true education is self-education, and they often regarded the expansion of formal educational opportunities with suspicion."
  • Over the past 150 years, it has become increasingly difficult to extricate reading from academic expectations; but I believe that such extrication is necessary. Education is and should be primarily about intellectual navigation, about—I scruple not to say it—skimming well, and reading carefully for information in order to upload content. Slow and patient reading, by contrast, properly belongs to our leisure hours.
  • There is a kind of attentiveness proper to school, to purposeful learning of all kinds, but in general it is closer to "hyper attention" than to "deep attention." I would argue that even reading for information—reading textbooks and the like—does not require extended unbroken focus. It requires discipline but not raptness, I think: The crammer chains himself to the textbook because of time pressures, not because the book itself requires unbroken concentration. Given world enough and time, the harried student could read for a while, do something else, come back and refresh his memory, take another break ... but the reader of even the most intellectually demanding work of literary art would lose a great deal by following such tactics. No novel or play or long poem will offer its full rewards to someone who consumes it in small chunks and crumbs. The attention it demands is the deep kind.
