  • When you think of heart attacks, you might assume the most common causes are smoking, high cholesterol, or obesity. Mental health issues probably don't spring to mind.
  • Depression—which for this study, was determined by a checklist of mood symptoms, including anxiety and fatigue
  • “depressed mood and exhaustion holds a solid middle position within the concert of major cardiovascular risk factors.”
  • sissij on 30 Jan 17
     
    I think it is really interesting that even mental health issues has a positive relationship with cardiovascular disease. Our mind can affect how our body works. As we learn in the sense and perception unit, we know that brain will give us a shot of certain chemical that makes us feel good when we make certain decision. I think how we feel can reflect how our body feels. We all know that we feel pain because it is a warning that the injured part of our body send to our brain. So I think probably the feeling of depressed can be a warning sent by some part of our body. The scientific method mentioned in this article is a population research which is a typical biology scientific method. --Sissi (1/29/2017)

  • Mr Gurría said a recent warning that a serious outbreak could halve global growth to 1.5% already looked too optimistic.

  • While the number of job losses and company failures remains uncertain, Mr Gurría said countries would be dealing with the economic fallout "for years to come".
  • "Even if you don't get a worldwide recession, you're going to get either no growth or negative growth in many of the economies of the world, including some of the larger ones, and therefore you're going to get not only low growth this year, but also it's going to take longer to pick up in the in the future,"
  • the reason is that we don't know how much it's going to take to fix the unemployment because we don't know how many people are going to end up unemployed. We also don't know how much it's going to take to fix the hundreds of thousands of small and medium enterprises who are already suffering
  • Mr Gurría called on governments to rip up borrowing rules and "throw everything we got at it" to deal with the crisis.
  • However, he warned that bigger deficits and larger debt piles would also weigh on heavily indebted countries for years to come.
  • Mr Gurría said that just weeks ago, policymakers from the G20 club of rich nations believed the recovery would take a 'V' shape - with a short, sharp drop in economic activity followed swiftly by a rebound in growth."It was already then mostly wishful thinking," he said.
  • It's going to be more in the best of cases like a 'U' with a long trench in the bottom before it gets to the recovery period. We can avoid it looking like an 'L', if we take the right decisions today."

  • Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.
  • Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.
  • ...9 more annotations...
  • Hodgson's findings have stunned the wine industry. Over the years he has shown again and again that even trained, professional palates are terrible at judging wine."The results are disturbing," says Hodgson from the Fieldbrook Winery in Humboldt County, described by its owner as a rural paradise. "Only about 10% of judges are consistent and those judges who were consistent one year were ordinary the next year."Chance has a great deal to do with the awards that wines win."
  • French academic Frédéric Brochet tested the effect of labels in 2001. He presented the same Bordeaux superior wine to 57 volunteers a week apart and in two different bottles – one for a table wine, the other for a grand cru.The tasters were fooled.When tasting a supposedly superior wine, their language was more positive – describing it as complex, balanced, long and woody. When the same wine was presented as plonk, the critics were more likely to use negatives such as weak, light and flat.
  • In 2011 Professor Richard Wiseman, a psychologist (and former professional magician) at Hertfordshire University invited 578 people to comment on a range of red and white wines, varying from £3.49 for a claret to £30 for champagne, and tasted blind.People could tell the difference between wines under £5 and those above £10 only 53% of the time for whites and only 47% of the time for reds. Overall they would have been just as a successful flipping a coin to guess.
  • why are ordinary drinkers and the experts so poor at tasting blind? Part of the answer lies in the sheer complexity of wine.For a drink made by fermenting fruit juice, wine is a remarkably sophisticated chemical cocktail. Dr Bryce Rankine, an Australian wine scientist, identified 27 distinct organic acids in wine, 23 varieties of alcohol in addition to the common ethanol, more than 80 esters and aldehydes, 16 sugars, plus a long list of assorted vitamins and minerals that wouldn't look out of place on the ingredients list of a cereal pack. There are even harmless traces of lead and arsenic that come from the soil.
  • "People underestimate how clever the olfactory system is at detecting aromas and our brain is at interpreting them," says Hutchinson."The olfactory system has the complexity in terms of its protein receptors to detect all the different aromas, but the brain response isn't always up to it. But I'm a believer that everyone has the same equipment and it comes down to learning how to interpret it." Within eight tastings, most people can learn to detect and name a reasonable range of aromas in wine
  • People struggle with assessing wine because the brain's interpretation of aroma and bouquet is based on far more than the chemicals found in the drink. Temperature plays a big part. Volatiles in wine are more active when wine is warmer. Serve a New World chardonnay too cold and you'll only taste the overpowering oak. Serve a red too warm and the heady boozy qualities will be overpowering.
  • Colour affects our perceptions too. In 2001 Frédérick Brochet of the University of Bordeaux asked 54 wine experts to test two glasses of wine – one red, one white. Using the typical language of tasters, the panel described the red as "jammy' and commented on its crushed red fruit.The critics failed to spot that both wines were from the same bottle. The only difference was that one had been coloured red with a flavourless dye
  • Other environmental factors play a role. A judge's palate is affected by what she or he had earlier, the time of day, their tiredness, their health – even the weather.
  • Robert Hodgson is determined to improve the quality of judging. He has developed a test that will determine whether a judge's assessment of a blind-tasted glass in a medal competition is better than chance. The research will be presented at a conference in Cape Town this year. But the early findings are not promising."So far I've yet to find someone who passes," he says.

  • The risks include loss of legal rights to data if it is stored on a company's machine's rather than your own, Stallman points out: "In the US, you even lose legal rights if you store your data in a company's machines instead of your own. The police need to present you with a search warrant to get your data from you; but if they are stored in a company's server, the police can get it without showing you anything. They may not even have to give the company a search warrant."
  • "I think that marketers like "cloud computing" because it is devoid of substantive meaning. The term's meaning is not substance, it's an attitude: 'Let any Tom, Dick and Harry hold your data, let any Tom, Dick and Harry do your computing for you (and control it).' Perhaps the term 'careless computing' would suit it better."

  • the stark partisan divide over issues that should be simply factual, like whether the planet is warming or evolution happened.
  • The problem, in other words, isn’t ignorance; it’s wishful thinking. Confronted with a conflict between evidence and what they want to believe for political and/or religious reasons, many people reject the evidence. And knowing more about the issues widens the divide, because the well informed have a clearer view of which evidence they need to reject to sustain their belief system.
  • In fact, hardly any of the people who predicted runaway inflation have acknowledged that they were wrong, and that the error suggests something amiss with their approach. Some have offered lame excuses; some, following in the footsteps of climate-change deniers, have gone down the conspiracy-theory rabbit hole, claiming that we really do have soaring inflation, but the government is lying about the numbers

  • Above all, there were many dire warnings about the evils of “printing money.” For example, in May 2009 an editorial in The Wall Street Journal warned that both interest rates and inflation were set to surge “now that Congress and the Federal Reserve have flooded the world with dollars.” In 2010 a virtual Who’s Who of conservative economists and pundits sent an open letter to Ben Bernanke warning that his policies risked “currency debasement and inflation.”
  • Although the Fed continued on its expansionary course — its balance sheet has grown to more than $4 trillion, up fivefold since the start of the crisis — inflation stayed low. For the most part, the funds the Fed injected into the economy simply piled up either in bank reserves or in cash holdings by individuals — which was exactly what economists on the other side of the divide had predicted would happen.

  • Well, it turns out that money is indeed a kind of theological issue. Many on the right are hostile to any kind of government activism, seeing it as the thin edge of the wedge — if you concede that the Fed can sometimes help the economy by creating “fiat money,” the next thing you know liberals will confiscate your wealth and give it to the 47 percent.

  • The NYU professor was surely prophetic. “Our own tribe is undergoing a vast and trembling shift from the magic of writing to the magic of electronics,” he cautioned.
  • “We face the rapid dissolution of the assumptions of an education organised around the slow-moving printed word, and the equally rapid emergence of a new education based on the speed-of-light electronic message.”
  • What Postman perceived in television has been dramatically intensified by smartphones and social media
  • ...31 more annotations...
  • Postman also recognised that technology was changing our mental processes and social habits.
  • Today corporations like Google and Amazon collect data on Internet users based on their browsing history, the things they purchase, and the apps they use
  • Yet all citizens are undergoing this same transformation. Our digital devices undermine social interactions by isolating us,
  • “Years from now, it will be noticed that the massive collection and speed-of-light retrieval of data have been of great value to large-scale organisations, but have solved very little of importance to most people, and have created at least as many problems for them as they may have solved.”
  • “Television has by its power to control the time, attention, and cognitive habits of our youth gained the power to control their education.”
  • As a student of Canadian philosopher Marshall McLuhan, Postman believed that the medium of information was critical to understanding its social and political effects. Every technology has its own agenda. Postman worried that the very nature of television undermined American democratic institutions.
  • Many Americans tuned in to the presidential debate looking for something substantial and meaty
  • It was simply another manifestation of the incoherence and vitriol of cable news
  • “When, in short, a people become an audience and their public business a vaudeville act, then a nation finds itself at risk; culture-death is a clear possibility,” warned Postman.
  • Technology Is Never Neutral
  • As for new problems, we have increased addictions (technological and pornographic); increased loneliness, anxiety, and distraction; and inhibited social and intellectual maturation.
  • The average length of a shot on network television is only 3.5 seconds, so that the eye never rests, always has something new to see. Moreover, television offers viewers a variety of subject matter, requires minimal skills to comprehend it, and is largely aimed at emotional gratification.
  • This is far truer of the Internet and social media, where more than a third of Americans, and almost half of young people, now get their news.
  • with smartphones now ubiquitous, the Internet has replaced television as the “background radiation of the social and intellectual universe.”
  • Is There Any Solution?
  • Reading news or commentary in print, in contrast, requires concentration, patience, and careful reflection, virtues that our digital age vitiates.
  • Politics as Entertainment
  • “How television stages the world becomes the model for how the world is properly to be staged,” observed Postman. In the case of politics, television fashions public discourse into yet another form of entertainment
  • In America, the fundamental metaphor for political discourse is the television commercial. The television commercial is not at all about the character of products to be consumed. … They tell everything about the fears, fancies, and dreams of those who might buy them.
  • The television commercial has oriented business away from making products of value and towards making consumers feel valuable, which means that the business of business has now become pseudo-therapy. The consumer is a patient assured by psycho-dramas.
  • Such is the case with the way politics is “advertised” to different subsets of the American electorate. The “consumer,” depending on his political leanings, may be manipulated by fears of either an impending white-nationalist, fascist dictatorship, or a radical, woke socialist takeover.
  • This paradigm is aggravated by the hypersiloing of media content, which explains why Americans who read left-leaning media view the Proud Boys as a legitimate, existential threat to national civil order, while those who read right-leaning media believe the real immediate enemies of our nation are Antifa
  • Regardless of whether either of these groups represents a real public menace, the loss of any national consensus over what constitutes objective news means that Americans effectively talk past one another: they use the Proud Boys or Antifa as rhetorical barbs to smear their ideological opponents as extremists.
  • Yet these technologies are far from neutral. They are, rather, “equipped with a program for social change.
  • Postman’s analysis of technology is prophetic and profound. He warned of the trivialising of our media, defined by “broken time and broken attention,” in which “facts push other facts into and then out of consciousness at speeds that neither permit nor require evaluation.” He warned of “a neighborhood of strangers and pointless quantity.”
  • does Postman offer any solutions to this seemingly uncontrollable technological juggernaut?
  • Postman’s suggestions regarding education are certainly relevant. He unequivocally condemned education that mimics entertainment, and urged a return to learning that is hierarchical, meaning that it first gives students a foundation of essential knowledge before teaching “critical thinking.”
  • Postman also argued that education must avoid a lowest-common-denominator approach in favor of complexity and the perplexing: the latter method elicits in the student a desire to make sense of what perplexes him.
  • Finally, Postman promoted education of vigorous exposition, logic, and rhetoric, all being necessary for citizenship
  • Another course of action is to understand what these media, by their very nature, do to us and to public discourse.
  • We must, as Postman exhorts us, “demystify the data” and dominate our technology, lest it dominate us. We must identify and resist how television, social media, and smartphones manipulate our emotions, infantilise us, and weaken our ability to rebuild what 2020 has ravaged.

In 1972, as a graduate student at the University of Edinburgh, Dr. Hinton embraced an idea called a neural network. A neural network is a mathematical system that learns skills by analyzing data. At the time, few researchers believed in the idea. But it became his life’s work.
  • Dr. Hinton is deeply opposed to the use of artificial intelligence on the battlefield — what he calls “robot soldiers.”
  • In 2012, Dr. Hinton and two of his students in Toronto, Ilya Sutskever and Alex Krishevsky, built a neural network that could analyze thousands of photos and teach itself to identify common objects, such as flowers, dogs and cars.
  • In 2018, Dr. Hinton and two other longtime collaborators received the Turing Award, often called “the Nobel Prize of computing,” for their work on neural networks.
  • Around the same time, Google, OpenAI and other companies began building neural networks that learned from huge amounts of digital text. Dr. Hinton thought it was a powerful way for machines to understand and generate language, but it was inferior to the way humans handled language.
  • Then, last year, as Google and OpenAI built systems using much larger amounts of data, his view changed. He still believed the systems were inferior to the human brain in some ways but he thought they were eclipsing human intelligence in others.
  • “Maybe what is going on in these systems,” he said, “is actually a lot better than what is going on in the brain.”
  • As companies improve their A.I. systems, he believes, they become increasingly dangerous. “Look at how it was five years ago and how it is now,” he said of A.I. technology. “Take the difference and propagate it forwards. That’s scary.”
  • Until last year, he said, Google acted as a “proper steward” for the technology, careful not to release something that might cause harm. But now that Microsoft has augmented its Bing search engine with a chatbot — challenging Google’s core business — Google is racing to deploy the same kind of technology. The tech giants are locked in a competition that might be impossible to stop, Dr. Hinton said.
  • His immediate concern is that the internet will be flooded with false photos, videos and text, and the average person will “not be able to know what is true anymore.”
  • He is also worried that A.I. technologies will in time upend the job market. Today, chatbots like ChatGPT tend to complement human workers, but they could replace paralegals, personal assistants, translators and others who handle rote tasks. “It takes away the drudge work,” he said. “It might take away more than that.”
  • Down the road, he is worried that future versions of the technology pose a threat to humanity because they often learn unexpected behavior from the vast amounts of data they analyze. This becomes an issue, he said, as individuals and companies allow A.I. systems not only to generate their own computer code but actually run that code on their ow
  • And he fears a day when truly autonomous weapons — those killer robots — become reality.
  • “The idea that this stuff could actually get smarter than people — a few people believed that,” he said. “But most people thought it was way off. And I thought it was way off. I thought it was 30 to 50 years or even longer away. Obviously, I no longer think that.”
  • Many other experts, including many of his students and colleagues, say this threat is hypothetical. But Dr. Hinton believes that the race between Google and Microsoft and others will escalate into a global race that will not stop without some sort of global regulation.
  • But that may be impossible, he said. Unlike with nuclear weapons, he said, there is no way of knowing whether companies or countries are working on the technology in secret. The best hope is for the world’s leading scientists to collaborate on ways of controlling the technology. “I don’t think they should scale this up more until they have understood whether they can control it,” he said.
  • Dr. Hinton said that when people used to ask him how he could work on technology that was potentially dangerous, he would paraphrase Robert Oppenheimer, who led the U.S. effort to build the atomic bomb: “When you see something that is technically sweet, you go ahead and do it.”
  • He does not say that anymore.

    Although America is alleged to be the most free country in the world and always saying that it will liberate other countries and give them the freedom of speech, the speech is still not as free as it is supposed to be. Political correctness is an issue the governments all around the world won't step back from. I think we cannot be as free as we want because humans are social animal. As long as we are living in a society, we have to learn to negotiate and sometimes give up our own benefit or dream for the big picture of the society. It's always the people who held power and hold the society that place limits on free speech.

  • the Kremlin’s strategy emerged haphazardly, even misleadingly, over a tense and momentous week, as an emotional Mr. Putin acted out of what the officials described as a deep sense of betrayal and grievance, especially toward the United States and Europe.
  • Some of those decisions, particularly the one to invade Crimea, then took on a life of their own, analysts said, unleashing a wave of nationalistic fervor for the peninsula’s reunification with Russia that the Kremlin has so far proved unwilling, or perhaps unable, to tamp down.
  • The decision to invade Crimea, the officials and analysts said, was made not by the national security council but in secret among a smaller and shrinking circle of Mr. Putin’s closest and most trusted aides. The group excluded senior officials from the Ministry of Foreign Affairs or the cadre of comparatively liberal advisers who might have foreseen the economic impact and potential consequences of American and European sanctions.
  • ...8 more annotations...
  • Mr. Putin’s decisions since the crisis began reflect instincts, political skills and emotions that have characterized his 14 years as Russia’s paramount leader, including a penchant for secrecy, loyalty and respect, for him and for Russia. They also suggest a deepening frustration with other world leaders that has left him impervious to threats of sanctions or international isolation
  • Because of Mr. Putin’s centralized authority, Russia’s policies and actions in moments of crisis can appear confused or hesitant until Mr. Putin himself decides on a course of action
  • Mr. Putin, by his own account at a news conference on Tuesday, warned Mr. Yanukovych not to withdraw the government’s security forces from Kiev, one of the demands of the agreement being negotiated.
  • By the next day, however, Ukraine’s Parliament had stripped Mr. Yanukovych of his powers, voted to release the opposition leader Yulia V. Tymoshenko from prison and scheduled new presidential elections. Russia’s initial response was muted, but officials have since said that Mr. Putin fumed that the Europeans who had mediated the agreement did nothing to enforce it.
  • The group, the officials and analysts said, included Sergei B. Ivanov, Mr. Putin’s chief of staff; Nikolai P. Patrushev, the secretary of the security council; and Aleksandr V. Bortnikov, the director of the Federal Security Service. All are veterans of the K.G.B., specifically colleagues of Mr. Putin’s when he served in the organization in Leningrad, now St. Petersburg, during the 1970s and ’80s.
  • “He has bit by bit winnowed out the people who challenged his worldview,” Mr. Galeotti said.
  • The deployment of the Russian forces — which the Ukrainian government has said ranged from 6,000 to 15,000 troops — remains a covert operation, the officials and analysts said, to sidestep international law and the need for approval by the United Nations Security Council, something that Mr. Putin and others have repeatedly insisted was necessary for any military operations against another country.
  • As long ago as 2008, when NATO leaders met in Bucharest to consider whether to invite Ukraine to begin moving toward membership, Mr. Putin bluntly warned that such membership would be unacceptable to Russia, presaging the strategy that appears to be unfolding now.

  • We rely on computers to fly our planes, find our cancers, design our buildings, audit our businesses. That's all well and good. But what happens when the computer fails?
  • On the evening of February 12, 2009, a Continental Connection commuter flight made its way through blustery weather between Newark, New Jersey, and Buffalo, New York.
  • The Q400 was well into its approach to the Buffalo airport, its landing gear down, its wing flaps out, when the pilot’s control yoke began to shudder noisily, a signal that the plane was losing lift and risked going into an aerodynamic stall. The autopilot disconnected, and the captain took over the controls. He reacted quickly, but he did precisely the wrong thing: he jerked back on the yoke, lifting the plane’s nose and reducing its airspeed, instead of pushing the yoke forward to gain velocity.
  • ...43 more annotations...
  • The crash, which killed all 49 people on board as well as one person on the ground, should never have happened.
  • aptain’s response to the stall warning, the investigators reported, “should have been automatic, but his improper flight control inputs were inconsistent with his training” and instead revealed “startle and confusion.
  • Automation has become so sophisticated that on a typical passenger flight, a human pilot holds the controls for a grand total of just three minutes.
  • We humans have been handing off chores, both physical and mental, to tools since the invention of the lever, the wheel, and the counting bead.
  • And that, many aviation and automation experts have concluded, is a problem. Overuse of automation erodes pilots’ expertise and dulls their reflexes,
  • No one doubts that autopilot has contributed to improvements in flight safety over the years. It reduces pilot fatigue and provides advance warnings of problems, and it can keep a plane airborne should the crew become disabled. But the steady overall decline in plane crashes masks the recent arrival of “a spectacularly new type of accident,”
  • “We’re forgetting how to fly.”
  • The experience of airlines should give us pause. It reveals that automation, for all its benefits, can take a toll on the performance and talents of those who rely on it. The implications go well beyond safety. Because automation alters how we act, how we learn, and what we know, it has an ethical dimension. The choices we make, or fail to make, about which tasks we hand off to machines shape our lives and the place we make for ourselves in the world.
  • What pilots spend a lot of time doing is monitoring screens and keying in data. They’ve become, it’s not much of an exaggeration to say, computer operators.
  • Examples of complacency and bias have been well documented in high-risk situations—on flight decks and battlefields, in factory control rooms—but recent studies suggest that the problems can bedevil anyone working with a computer
  • That may leave the person operating the computer to play the role of a high-tech clerk—entering data, monitoring outputs, and watching for failures. Rather than opening new frontiers of thought and action, software ends up narrowing our focus.
  • A labor-saving device doesn’t just provide a substitute for some isolated component of a job or other activity. It alters the character of the entire task, including the roles, attitudes, and skills of the people taking part.
  • when we work with computers, we often fall victim to two cognitive ailments—complacency and bias—that can undercut our performance and lead to mistakes. Automation complacency occurs when a computer lulls us into a false sense of security. Confident that the machine will work flawlessly and handle any problem that crops up, we allow our attention to drift.
  • Automation bias occurs when we place too much faith in the accuracy of the information coming through our monitors. Our trust in the software becomes so strong that we ignore or discount other information sources, including our own eyes and ears
  • Automation is different now. Computers can be programmed to perform complex activities in which a succession of tightly coordinated tasks is carried out through an evaluation of many variables. Many software programs take on intellectual work—observing and sensing, analyzing and judging, even making decisions—that until recently was considered the preserve of humans.
  • Automation turns us from actors into observers. Instead of manipulating the yoke, we watch the screen. That shift may make our lives easier, but it can also inhibit the development of expertise.
  • Since the late 1970s, psychologists have been documenting a phenomenon called the “generation effect.” It was first observed in studies of vocabulary, which revealed that people remember words much better when they actively call them to mind—when they generate them—than when they simply read them.
  • When you engage actively in a task, you set off intricate mental processes that allow you to retain more knowledge. You learn more and remember more. When you repeat the same task over a long period, your brain constructs specialized neural circuits dedicated to the activit
  • What looks like instinct is hard-won skill, skill that requires exactly the kind of struggle that modern software seeks to alleviate.
  • In many businesses, managers and other professionals have come to depend on decision-support systems to analyze information and suggest courses of action. Accountants, for example, use the systems in corporate audits. The applications speed the work, but some signs suggest that as the software becomes more capable, the accountants become less so.
  • You can put limits on the scope of automation, making sure that people working with computers perform challenging tasks rather than merely observing.
  • Experts used to assume that there were limits to the ability of programmers to automate complicated tasks, particularly those involving sensory perception, pattern recognition, and conceptual knowledge
  • Who needs humans, anyway? That question, in one rhetorical form or another, comes up frequently in discussions of automation. If computers’ abilities are expanding so quickly and if people, by comparison, seem slow, clumsy, and error-prone, why not build immaculately self-contained systems that perform flawlessly without any human oversight or intervention? Why not take the human factor out of the equation?
  • The cure for imperfect automation is total automation.
  • That idea is seductive, but no machine is infallible. Sooner or later, even the most advanced technology will break down, misfire, or, in the case of a computerized system, encounter circumstances that its designers never anticipated. As automation technologies become more complex, relying on interdependencies among algorithms, databases, sensors, and mechanical parts, the potential sources of failure multiply. They also become harder to detect.
  • conundrum of computer automation.
  • Because many system designers assume that human operators are “unreliable and inefficient,” at least when compared with a computer, they strive to give the operators as small a role as possible.
  • People end up functioning as mere monitors, passive watchers of screens. That’s a job that humans, with our notoriously wandering minds, are especially bad at
  • people have trouble maintaining their attention on a stable display of information for more than half an hour. “This means,” Bainbridge observed, “that it is humanly impossible to carry out the basic function of monitoring for unlikely abnormalities.”
  • a person’s skills “deteriorate when they are not used,” even an experienced operator will eventually begin to act like an inexperienced one if restricted to just watching.
  • You can program software to shift control back to human operators at frequent but irregular intervals; knowing that they may need to take command at any moment keeps people engaged, promoting situational awareness and learning.
  • What’s most astonishing, and unsettling, about computer automation is that it’s still in its early stages.
  • most software applications don’t foster learning and engagement. In fact, they have the opposite effect. That’s because taking the steps necessary to promote the development and maintenance of expertise almost always entails a sacrifice of speed and productivity.
  • Learning requires inefficiency. Businesses, which seek to maximize productivity and profit, would rarely accept such a trade-off. Individuals, too, almost always seek efficiency and convenience.
  • Abstract concerns about the fate of human talent can’t compete with the allure of saving time and money.
  • The small island of Igloolik, off the coast of the Melville Peninsula in the Nunavut territory of northern Canada, is a bewildering place in the winter.
  • , Inuit hunters have for some 4,000 years ventured out from their homes on the island and traveled across miles of ice and tundra to search for game. The hunters’ ability to navigate vast stretches of the barren Arctic terrain, where landmarks are few, snow formations are in constant flux, and trails disappear overnight, has amazed explorers and scientists for centuries. The Inuit’s extraordinary way-finding skills are born not of technological prowess—they long eschewed maps and compasses—but of a profound understanding of winds, snowdrift patterns, animal behavior, stars, and tides.
  • The Igloolik hunters have begun to rely on computer-generated maps to get around. Adoption of GPS technology has been particularly strong among younger Inuit, and it’s not hard to understand why.
  • But as GPS devices have proliferated on Igloolik, reports of serious accidents during hunts have spread. A hunter who hasn’t developed way-finding skills can easily become lost, particularly if his GPS receiver fails.
  • The routes so meticulously plotted on satellite maps can also give hunters tunnel vision, leading them onto thin ice or into other hazards a skilled navigator would avoid.
  • An Inuit on a GPS-equipped snowmobile is not so different from a suburban commuter in a GPS-equipped SUV: as he devotes his attention to the instructions coming from the computer, he loses sight of his surroundings. He travels “blindfolded,” as Aporta puts it
  • A unique talent that has distinguished a people for centuries may evaporate in a generation.
  • Computer automation severs the ends from the means. It makes getting what we want easier, but it distances us from the work of knowing. As we transform ourselves into creatures of the screen, we face an existential question: Does our essence still lie in what we know, or are we now content to be defined by what we want?

  • What’s disheartening is how bad they are at thinking and talking about moral issues.
  • you see the young people groping to say anything sensible on these matters. But they just don’t have the categories or vocabulary to do so.
  • “Not many of them have previously given much or any thought to many of the kinds of questions about morality that we asked,” Smith and his co-authors write. When asked about wrong or evil, they could generally agree that rape and murder are wrong. But, aside from these extreme cases, moral thinking didn’t enter the picture, even when considering things like drunken driving, cheating in school or cheating on a partner.
  • ...8 more annotations...
  • The default position, which most of them came back to again and again, is that moral choices are just a matter of individual taste. “It’s personal,” the respondents typically said. “It’s up to the individual. Who am I to say?”
  • “I would do what I thought made me happy or how I felt. I have no other way of knowing what to do but how I internally feel.”
  • their attitudes at the start of their adult lives do reveal something about American culture. For decades, writers from different perspectives have been warning about the erosion of shared moral frameworks and the rise of an easygoing moral individualism. Allan Bloom and Gertrude Himmelfarb warned that sturdy virtues are being diluted into shallow values. Alasdair MacIntyre has written about emotivism, the idea that it’s impossible to secure moral agreement in our culture because all judgments are based on how we feel at the moment. Charles Taylor has argued that morals have become separated from moral sources. People are less likely to feel embedded on a moral landscape that transcends self. James Davison Hunter wrote a book called “The Death of Character.” Smith’s interviewees are living, breathing examples of the trends these writers have described.
  • Smith and company found an atmosphere of extreme moral individualism — of relativism and nonjudgmentalism.
  • they have not been given the resources — by schools, institutions and families — to cultivate their moral intuitions, to think more broadly about moral obligations, to check behaviors that may be degrading.
  • the interviewees were so completely untroubled by rabid consumerism.
  • Many were quick to talk about their moral feelings but hesitant to link these feelings to any broader thinking about a shared moral framework or obligation. As one put it, “I mean, I guess what makes something right is how I feel about it. But different people feel different ways, so I couldn’t speak on behalf of anyone else as to what’s right and wrong.”
  • In most times and in most places, the group was seen to be the essential moral unit. A shared religion defined rules and practices. Cultures structured people’s imaginations and imposed moral disciplines. But now more people are led to assume that the free-floating individual is the essential moral unit. Morality was once revealed, inherited and shared, but now it’s thought of as something that emerges in the privacy of your own heart.
  • Richard Monari on 18 Sep 11
     
    Goodness, I went through a bit of emotion reading that. Whew. Gotta center. Anyhoo, I feel certainly conflicted over the author's idea of "shallow values." Personally, I don't necessarily see the need to have a shared moral framework to connect to. What is this framework if not a system to instill shame and obligation into its members? While I do think it's important to have an articulate moral opinion on relevant subjects, I also think the world cannot be divided into realms of right or wrong when we can barely see even an infinitely small part of it at one time. What's wrong with open-mindedness?
