Advertising Memory MInd

shared by Weiye Loh on 29 May 11 - No Cached
  • The experiment went like this: 100 undergraduates were introduced to a new popcorn product called “Orville Redenbacher’s Gourmet Fresh Microwave Popcorn.” (No such product exists, but that’s the point.) Then, the students were randomly assigned to various advertisement conditions. Some subjects viewed low-imagery text ads, which described the delicious taste of this new snack food. Others watched a high-imagery commercial, in which they watched all sorts of happy people enjoying this popcorn in their living room. After viewing the ads, the students were then assigned to one of two rooms. In one room, they were given an unrelated survey. In the other room, however, they were given a sample of this fictional new popcorn to taste. (A different Orville Redenbacher popcorn was actually used.) One week later, all the subjects were quizzed about their memory of the product. Here’s where things get disturbing: While students who saw the low-imagery ad were extremely unlikely to report having tried the popcorn, those who watched the slick commercial were just as likely to have said they tried the popcorn as those who actually did. Furthermore, their ratings of the product were as favorable as those who sampled the salty, buttery treat. Most troubling, perhaps, is that these subjects were extremely confident in these made-up memories. The delusion felt true. They didn’t like the popcorn because they’d seen a good ad. They liked the popcorn because it was delicious.
  • “false experience effect,”
  • “Viewing the vivid advertisement created a false memory of eating the popcorn, despite the fact that eating the non-existent product would have been impossible,” write Priyali Rajagopal and Nicole Montgomery, the lead authors on the paper. “As a result, consumers need to be vigilant while processing high-imagery advertisements.”

  • How could a stupid commercial trick me into believing that I loved a product I’d never actually tasted? Or that I drank Coke out of glass bottles? The answer returns us to a troubling recent theory known as memory reconsolidation. In essence, reconsolidation is rooted in the fact that every time we recall a memory we also remake it, subtly tweaking the neuronal details. Although we like to think of our memories as being immutable impressions, somehow separate from the act of remembering them, they aren’t. A memory is only as real as the last time you remembered it. What’s disturbing, of course, is that we can’t help but borrow many of our memories from elsewhere, so that the ad we watched on television becomes our own, part of that personal narrative we repeat and retell.
  • This idea, simple as it seems, requires us to completely re-imagine our assumptions about memory.  It reveals memory as a ceaseless process, not a repository of inert information. The recall is altered in the absence of the original stimulus, becoming less about what we actually remember and more about what we’d like to remember. It’s the difference between a “Save” and the “Save As” function. Our memories are a “Save As”: They are files that get rewritten every time we remember them, which is why the more we remember something, the less accurate the memory becomes. And so that pretty picture of popcorn becomes a taste we definitely remember, and that alluring soda commercial becomes a scene from my own life. We steal our stories from everywhere. Marketers, it turns out, are just really good at giving us stories we want to steal.

    A new study, published in The Journal of Consumer Research, helps explain both the success of this marketing strategy and my flawed nostalgia for Coke. It turns out that vivid commercials are incredibly good at tricking the hippocampus (a center of long-term memory in the brain) into believing that the scene we just watched on television actually happened. And it happened to us.

Memory Search Google Transactive Memory

shared by Weiye Loh on 15 Jul 11 - No Cached
  • study co-author and Columbia University psychologist Elizabeth Sparrow said it’s just another form of so-called transactive memory, exhibited by people working in groups in which facts and expertise are distributed.
  • A direct comparison of transactive learning by individuals in groups and on computers has not been performed. It would be interesting to see how they stack up, said Sparrow. It would also be interesting to further compare how transactive and internal memory function. They could affect other thought processes: For example, someone relying on internalized memory may review and synthesize other memories during recall. One small but intriguing effect in the new study involved students who were less able to identify subtly manipulated facts, such as a changed name or date, when drawing on memories they thought were saved online.
  • Weiye Loh on 15 Jul 11
     
    Thanks to search engines, most simple facts don't need to be remembered. They can be accessed with a few keystrokes, plucked from ubiquitous server-stored external memory - and that may be changing how our own memories are maintained. A study of 46 college students found lower rates of recall on newly-learned facts when students thought those facts were saved on a computer for later recovery. If you think a fact is conveniently available online, then, you may be less apt to learn it.

Information Language Data History Science

  • Another example illustrating the central dogma is the French optical telegraph.
  • The telegraph was an optical communication system with stations consisting of large movable pointers mounted on the tops of sixty-foot towers. Each station was manned by an operator who could read a message transmitted by a neighboring station and transmit the same message to the next station in the transmission line.
  • The distance between neighbors was about seven miles. Along the transmission lines, optical messages in France could travel faster than drum messages in Africa. When Napoleon took charge of the French Republic in 1799, he ordered the completion of the optical telegraph system to link all the major cities of France from Calais and Paris to Toulon and onward to Milan. The telegraph became, as Claude Chappe had intended, an important instrument of national power. Napoleon made sure that it was not available to private users.

  • Unlike the drum language, which was based on spoken language, the optical telegraph was based on written French. Chappe invented an elaborate coding system to translate written messages into optical signals. Chappe had the opposite problem from the drummers. The drummers had a fast transmission system with ambiguous messages. They needed to slow down the transmission to make the messages unambiguous. Chappe had a painfully slow transmission system with redundant messages. The French language, like most alphabetic languages, is highly redundant, using many more letters than are needed to convey the meaning of a message. Chappe’s coding system allowed messages to be transmitted faster. Many common phrases and proper names were encoded by only two optical symbols, with a substantial gain in speed of transmission. The composer and the reader of the message had code books listing the message codes for eight thousand phrases and names. For Napoleon it was an advantage to have a code that was effectively cryptographic, keeping the content of the messages secret from citizens along the route.
  • After these two historical examples of rapid communication in Africa and France, the rest of Gleick’s book is about the modern development of information technolog
  • The modern history is dominated by two Americans, Samuel Morse and Claude Shannon. Samuel Morse was the inventor of Morse Code. He was also one of the pioneers who built a telegraph system using electricity conducted through wires instead of optical pointers deployed on towers. Morse launched his electric telegraph in 1838 and perfected the code in 1844. His code used short and long pulses of electric current to represent letters of the alphabet.
  • Morse was ideologically at the opposite pole from Chappe. He was not interested in secrecy or in creating an instrument of government power. The Morse system was designed to be a profit-making enterprise, fast and cheap and available to everybody. At the beginning the price of a message was a quarter of a cent per letter. The most important users of the system were newspaper correspondents spreading news of local events to readers all over the world. Morse Code was simple enough that anyone could learn it. The system provided no secrecy to the users. If users wanted secrecy, they could invent their own secret codes and encipher their messages themselves. The price of a message in cipher was higher than the price of a message in plain text, because the telegraph operators could transcribe plain text faster. It was much easier to correct errors in plain text than in cipher.
  • Claude Shannon was the founding father of information theory. For a hundred years after the electric telegraph, other communication systems such as the telephone, radio, and television were invented and developed by engineers without any need for higher mathematics. Then Shannon supplied the theory to understand all of these systems together, defining information as an abstract quantity inherent in a telephone message or a television picture. Shannon brought higher mathematics into the game.
  • When Shannon was a boy growing up on a farm in Michigan, he built a homemade telegraph system using Morse Code. Messages were transmitted to friends on neighboring farms, using the barbed wire of their fences to conduct electric signals. When World War II began, Shannon became one of the pioneers of scientific cryptography, working on the high-level cryptographic telephone system that allowed Roosevelt and Churchill to talk to each other over a secure channel. Shannon’s friend Alan Turing was also working as a cryptographer at the same time, in the famous British Enigma project that successfully deciphered German military codes. The two pioneers met frequently when Turing visited New York in 1943, but they belonged to separate secret worlds and could not exchange ideas about cryptography.
  • In 1945 Shannon wrote a paper, “A Mathematical Theory of Cryptography,” which was stamped SECRET and never saw the light of day. He published in 1948 an expurgated version of the 1945 paper with the title “A Mathematical Theory of Communication.” The 1948 version appeared in the Bell System Technical Journal, the house journal of the Bell Telephone Laboratories, and became an instant classic. It is the founding document for the modern science of information. After Shannon, the technology of information raced ahead, with electronic computers, digital cameras, the Internet, and the World Wide Web.
  • According to Gleick, the impact of information on human affairs came in three installments: first the history, the thousands of years during which people created and exchanged information without the concept of measuring it; second the theory, first formulated by Shannon; third the flood, in which we now live
  • The event that made the flood plainly visible occurred in 1965, when Gordon Moore stated Moore’s Law. Moore was an electrical engineer, founder of the Intel Corporation, a company that manufactured components for computers and other electronic gadgets. His law said that the price of electronic components would decrease and their numbers would increase by a factor of two every eighteen months. This implied that the price would decrease and the numbers would increase by a factor of a hundred every decade. Moore’s prediction of continued growth has turned out to be astonishingly accurate during the forty-five years since he announced it. In these four and a half decades, the price has decreased and the numbers have increased by a factor of a billion, nine powers of ten. Nine powers of ten are enough to turn a trickle into a flood.
  • Gordon Moore was in the hardware business, making hardware components for electronic machines, and he stated his law as a law of growth for hardware. But the law applies also to the information that the hardware is designed to embody. The purpose of the hardware is to store and process information. The storage of information is called memory, and the processing of information is called computing. The consequence of Moore’s Law for information is that the price of memory and computing decreases and the available amount of memory and computing increases by a factor of a hundred every decade. The flood of hardware becomes a flood of information.
  • In 1949, one year after Shannon published the rules of information theory, he drew up a table of the various stores of memory that then existed. The biggest memory in his table was the US Library of Congress, which he estimated to contain one hundred trillion bits of information. That was at the time a fair guess at the sum total of recorded human knowledge. Today a memory disc drive storing that amount of information weighs a few pounds and can be bought for about a thousand dollars. Information, otherwise known as data, pours into memories of that size or larger, in government and business offices and scientific laboratories all over the world. Gleick quotes the computer scientist Jaron Lanier describing the effect of the flood: “It’s as if you kneel to plant the seed of a tree and it grows so fast that it swallows your whole town before you can even rise to your feet.”
  • On December 8, 2010, Gleick published on the The New York Review’s blog an illuminating essay, “The Information Palace.” It was written too late to be included in his book. It describes the historical changes of meaning of the word “information,” as recorded in the latest quarterly online revision of the Oxford English Dictionary. The word first appears in 1386 a parliamentary report with the meaning “denunciation.” The history ends with the modern usage, “information fatigue,” defined as “apathy, indifference or mental exhaustion arising from exposure to too much information.”
  • The consequences of the information flood are not all bad. One of the creative enterprises made possible by the flood is Wikipedia, started ten years ago by Jimmy Wales. Among my friends and acquaintances, everybody distrusts Wikipedia and everybody uses it. Distrust and productive use are not incompatible. Wikipedia is the ultimate open source repository of information. Everyone is free to read it and everyone is free to write it. It contains articles in 262 languages written by several million authors. The information that it contains is totally unreliable and surprisingly accurate. It is often unreliable because many of the authors are ignorant or careless. It is often accurate because the articles are edited and corrected by readers who are better informed than the authors
  • Jimmy Wales hoped when he started Wikipedia that the combination of enthusiastic volunteer writers with open source information technology would cause a revolution in human access to knowledge. The rate of growth of Wikipedia exceeded his wildest dreams. Within ten years it has become the biggest storehouse of information on the planet and the noisiest battleground of conflicting opinions. It illustrates Shannon’s law of reliable communication. Shannon’s law says that accurate transmission of information is possible in a communication system with a high level of noise. Even in the noisiest system, errors can be reliably corrected and accurate information transmitted, provided that the transmission is sufficiently redundant. That is, in a nutshell, how Wikipedia works.
  • The information flood has also brought enormous benefits to science. The public has a distorted view of science, because children are taught in school that science is a collection of firmly established truths. In fact, science is not a collection of truths. It is a continuing exploration of mysteries. Wherever we go exploring in the world around us, we find mysteries. Our planet is covered by continents and oceans whose origin we cannot explain. Our atmosphere is constantly stirred by poorly understood disturbances that we call weather and climate. The visible matter in the universe is outweighed by a much larger quantity of dark invisible matter that we do not understand at all. The origin of life is a total mystery, and so is the existence of human consciousness. We have no clear idea how the electrical discharges occurring in nerve cells in our brains are connected with our feelings and desires and actions.
  • Even physics, the most exact and most firmly established branch of science, is still full of mysteries. We do not know how much of Shannon’s theory of information will remain valid when quantum devices replace classical electric circuits as the carriers of information. Quantum devices may be made of single atoms or microscopic magnetic circuits. All that we know for sure is that they can theoretically do certain jobs that are beyond the reach of classical devices. Quantum computing is still an unexplored mystery on the frontier of information theory. Science is the sum total of a great multitude of mysteries. It is an unending argument between a great multitude of voices. It resembles Wikipedia much more than it resembles the Encyclopaedia Britannica.
  • The rapid growth of the flood of information in the last ten years made Wikipedia possible, and the same flood made twenty-first-century science possible. Twenty-first-century science is dominated by huge stores of information that we call databases. The information flood has made it easy and cheap to build databases. One example of a twenty-first-century database is the collection of genome sequences of living creatures belonging to various species from microbes to humans. Each genome contains the complete genetic information that shaped the creature to which it belongs. The genome data-base is rapidly growing and is available for scientists all over the world to explore. Its origin can be traced to the year 1939, when Shannon wrote his Ph.D. thesis with the title “An Algebra for Theoretical Genetics.
  • Shannon was then a graduate student in the mathematics department at MIT. He was only dimly aware of the possible physical embodiment of genetic information. The true physical embodiment of the genome is the double helix structure of DNA molecules, discovered by Francis Crick and James Watson fourteen years later. In 1939 Shannon understood that the basis of genetics must be information, and that the information must be coded in some abstract algebra independent of its physical embodiment. Without any knowledge of the double helix, he could not hope to guess the detailed structure of the genetic code. He could only imagine that in some distant future the genetic information would be decoded and collected in a giant database that would define the total diversity of living creatures. It took only sixty years for his dream to come true.
  • In the twentieth century, genomes of humans and other species were laboriously decoded and translated into sequences of letters in computer memories. The decoding and translation became cheaper and faster as time went on, the price decreasing and the speed increasing according to Moore’s Law. The first human genome took fifteen years to decode and cost about a billion dollars. Now a human genome can be decoded in a few weeks and costs a few thousand dollars. Around the year 2000, a turning point was reached, when it became cheaper to produce genetic information than to understand it. Now we can pass a piece of human DNA through a machine and rapidly read out the genetic information, but we cannot read out the meaning of the information. We shall not fully understand the information until we understand in detail the processes of embryonic development that the DNA orchestrated to make us what we are.
  • The explosive growth of information in our human society is a part of the slower growth of ordered structures in the evolution of life as a whole. Life has for billions of years been evolving with organisms and ecosystems embodying increasing amounts of information. The evolution of life is a part of the evolution of the universe, which also evolves with increasing amounts of information embodied in ordered structures, galaxies and stars and planetary systems. In the living and in the nonliving world, we see a growth of order, starting from the featureless and uniform gas of the early universe and producing the magnificent diversity of weird objects that we see in the sky and in the rain forest. Everywhere around us, wherever we look, we see evidence of increasing order and increasing information. The technology arising from Shannon’s discoveries is only a local acceleration of the natural growth of information.
  • . Lord Kelvin, one of the leading physicists of that time, promoted the heat death dogma, predicting that the flow of heat from warmer to cooler objects will result in a decrease of temperature differences everywhere, until all temperatures ultimately become equal. Life needs temperature differences, to avoid being stifled by its waste heat. So life will disappear
  • Thanks to the discoveries of astronomers in the twentieth century, we now know that the heat death is a myth. The heat death can never happen, and there is no paradox. The best popular account of the disappearance of the paradox is a chapter, “How Order Was Born of Chaos,” in the book Creation of the Universe, by Fang Lizhi and his wife Li Shuxian.2 Fang Lizhi is doubly famous as a leading Chinese astronomer and a leading political dissident. He is now pursuing his double career at the University of Arizona.
  • The belief in a heat death was based on an idea that I call the cooking rule. The cooking rule says that a piece of steak gets warmer when we put it on a hot grill. More generally, the rule says that any object gets warmer when it gains energy, and gets cooler when it loses energy. Humans have been cooking steaks for thousands of years, and nobody ever saw a steak get colder while cooking on a fire. The cooking rule is true for objects small enough for us to handle. If the cooking rule is always true, then Lord Kelvin’s argument for the heat death is correct.
  • the cooking rule is not true for objects of astronomical size, for which gravitation is the dominant form of energy. The sun is a familiar example. As the sun loses energy by radiation, it becomes hotter and not cooler. Since the sun is made of compressible gas squeezed by its own gravitation, loss of energy causes it to become smaller and denser, and the compression causes it to become hotter. For almost all astronomical objects, gravitation dominates, and they have the same unexpected behavior. Gravitation reverses the usual relation between energy and temperature. In the domain of astronomy, when heat flows from hotter to cooler objects, the hot objects get hotter and the cool objects get cooler. As a result, temperature differences in the astronomical universe tend to increase rather than decrease as time goes on. There is no final state of uniform temperature, and there is no heat death. Gravitation gives us a universe hospitable to life. Information and order can continue to grow for billions of years in the future, as they have evidently grown in the past.
  • The vision of the future as an infinite playground, with an unending sequence of mysteries to be understood by an unending sequence of players exploring an unending supply of information, is a glorious vision for scientists. Scientists find the vision attractive, since it gives them a purpose for their existence and an unending supply of jobs. The vision is less attractive to artists and writers and ordinary people. Ordinary people are more interested in friends and family than in science. Ordinary people may not welcome a future spent swimming in an unending flood of information.
  • A darker view of the information-dominated universe was described in a famous story, “The Library of Babel,” by Jorge Luis Borges in 1941.3 Borges imagined his library, with an infinite array of books and shelves and mirrors, as a metaphor for the universe.
  • Gleick’s book has an epilogue entitled “The Return of Meaning,” expressing the concerns of people who feel alienated from the prevailing scientific culture. The enormous success of information theory came from Shannon’s decision to separate information from meaning. His central dogma, “Meaning is irrelevant,” declared that information could be handled with greater freedom if it was treated as a mathematical abstraction independent of meaning. The consequence of this freedom is the flood of information in which we are drowning. The immense size of modern databases gives us a feeling of meaninglessness. Information in such quantities reminds us of Borges’s library extending infinitely in all directions. It is our task as humans to bring meaning back into this wasteland. As finite creatures who think and feel, we can create islands of meaning in the sea of information. Gleick ends his book with Borges’s image of the human condition:We walk the corridors, searching the shelves and rearranging them, looking for lines of meaning amid leagues of cacophony and incoherence, reading the history of the past and of the future, collecting our thoughts and collecting the thoughts of others, and every so often glimpsing mirrors, in which we may recognize creatures of the information.

    In the age of Google and Wikipedia, an almost unlimited amount of information is available at our fingertips, and with the rise of smartphones, many of us have nonstop access. The potential to find almost any piece of information in seconds is beneficial, but is this ability actually negatively impacting our memory? The authors of a paper that is being released by Science Express describe four experiments testing this. Based on their results, people are recalling information less, and instead can remember where to find the information they have forgotten.

  • N.Y.U. professor Clay Shirky—the author of “Cognitive Surplus” and many articles and blog posts proclaiming the coming of the digital millennium—is the breeziest and seemingly most self-confident
  • Shirky believes that we are on the crest of an ever-surging wave of democratized information: the Gutenberg printing press produced the Reformation, which produced the Scientific Revolution, which produced the Enlightenment, which produced the Internet, each move more liberating than the one before.
  • The idea, for instance, that the printing press rapidly gave birth to a new order of information, democratic and bottom-up, is a cruel cartoon of the truth. If the printing press did propel the Reformation, one of the biggest ideas it propelled was Luther’s newly invented absolutist anti-Semitism. And what followed the Reformation wasn’t the Enlightenment, a new era of openness and freely disseminated knowledge. What followed the Reformation was, actually, the Counter-Reformation, which used the same means—i.e., printed books—to spread ideas about what jerks the reformers were, and unleashed a hundred years of religious warfare.
  • ...17 more annotations...
  • If ideas of democracy and freedom emerged at the end of the printing-press era, it wasn’t by some technological logic but because of parallel inventions, like the ideas of limited government and religious tolerance, very hard won from history.
  • As Andrew Pettegree shows in his fine new study, “The Book in the Renaissance,” the mainstay of the printing revolution in seventeenth-century Europe was not dissident pamphlets but royal edicts, printed by the thousand: almost all the new media of that day were working, in essence, for kinglouis.gov.
  • Even later, full-fledged totalitarian societies didn’t burn books. They burned some books, while keeping the printing presses running off such quantities that by the mid-fifties Stalin was said to have more books in print than Agatha Christie.
  • Many of the more knowing Never-Betters turn for cheer not to messy history and mixed-up politics but to psychology—to the actual expansion of our minds.
  • The argument, advanced in Andy Clark’s “Supersizing the Mind” and in Robert K. Logan’s “The Sixth Language,” begins with the claim that cognition is not a little processing program that takes place inside your head, Robby the Robot style. It is a constant flow of information, memory, plans, and physical movements, in which as much thinking goes on out there as in here. If television produced the global village, the Internet produces the global psyche: everyone keyed in like a neuron, so that to the eyes of a watching Martian we are really part of a single planetary brain. Contraptions don’t change consciousness; contraptions are part of consciousness. We may not act better than we used to, but we sure think differently than we did.
  • Cognitive entanglement, after all, is the rule of life. My memories and my wife’s intermingle. When I can’t recall a name or a date, I don’t look it up; I just ask her. Our machines, in this way, become our substitute spouses and plug-in companions.
  • But, if cognitive entanglement exists, so does cognitive exasperation. Husbands and wives deny each other’s memories as much as they depend on them. That’s fine until it really counts (say, in divorce court). In a practical, immediate way, one sees the limits of the so-called “extended mind” clearly in the mob-made Wikipedia, the perfect product of that new vast, supersized cognition: when there’s easy agreement, it’s fine, and when there’s widespread disagreement on values or facts, as with, say, the origins of capitalism, it’s fine, too; you get both sides. The trouble comes when one side is right and the other side is wrong and doesn’t know it. The Shakespeare authorship page and the Shroud of Turin page are scenes of constant conflict and are packed with unreliable information. Creationists crowd cyberspace every bit as effectively as evolutionists, and extend their minds just as fully. Our trouble is not the over-all absence of smartness but the intractable power of pure stupidity, and no machine, or mind, seems extended enough to cure that.
  • Nicholas Carr, in “The Shallows,” William Powers, in “Hamlet’s BlackBerry,” and Sherry Turkle, in “Alone Together,” all bear intimate witness to a sense that the newfound land, the ever-present BlackBerry-and-instant-message world, is one whose price, paid in frayed nerves and lost reading hours and broken attention, is hardly worth the gains it gives us. “The medium does matter,” Carr has written. “As a technology, a book focuses our attention, isolates us from the myriad distractions that fill our everyday lives. A networked computer does precisely the opposite. It is designed to scatter our attention. . . . Knowing that the depth of our thought is tied directly to the intensity of our attentiveness, it’s hard not to conclude that as we adapt to the intellectual environment of the Net our thinking becomes shallower.
  • Carr is most concerned about the way the Internet breaks down our capacity for reflective thought.
  • Powers’s reflections are more family-centered and practical. He recounts, very touchingly, stories of family life broken up by the eternal consultation of smartphones and computer monitors
  • He then surveys seven Wise Men—Plato, Thoreau, Seneca, the usual gang—who have something to tell us about solitude and the virtues of inner space, all of it sound enough, though he tends to overlook the significant point that these worthies were not entirely in favor of the kinds of liberties that we now take for granted and that made the new dispensation possible.
  • Similarly, Nicholas Carr cites Martin Heidegger for having seen, in the mid-fifties, that new technologies would break the meditational space on which Western wisdoms depend. Since Heidegger had not long before walked straight out of his own meditational space into the arms of the Nazis, it’s hard to have much nostalgia for this version of the past. One feels the same doubts when Sherry Turkle, in “Alone Together,” her touching plaint about the destruction of the old intimacy-reading culture by the new remote-connection-Internet culture, cites studies that show a dramatic decline in empathy among college students, who apparently are “far less likely to say that it is valuable to put oneself in the place of others or to try and understand their feelings.” What is to be done?
  • Among Ever-Wasers, the Harvard historian Ann Blair may be the most ambitious. In her book “Too Much to Know: Managing Scholarly Information Before the Modern Age,” she makes the case that what we’re going through is like what others went through a very long while ago. Against the cartoon history of Shirky or Tooby, Blair argues that the sense of “information overload” was not the consequence of Gutenberg but already in place before printing began. She wants us to resist “trying to reduce the complex causal nexus behind the transition from Renaissance to Enlightenment to the impact of a technology or any particular set of ideas.” Anyway, the crucial revolution was not of print but of paper: “During the later Middle Ages a staggering growth in the production of manuscripts, facilitated by the use of paper, accompanied a great expansion of readers outside the monastic and scholastic contexts.” For that matter, our minds were altered less by books than by index slips. Activities that seem quite twenty-first century, she shows, began when people cut and pasted from one manuscript to another; made aggregated news in compendiums; passed around précis. “Early modern finding devices” were forced into existence: lists of authorities, lists of headings.
  • Everyone complained about what the new information technologies were doing to our minds. Everyone said that the flood of books produced a restless, fractured attention. Everyone complained that pamphlets and poems were breaking kids’ ability to concentrate, that big good handmade books were ignored, swept aside by printed works that, as Erasmus said, “are foolish, ignorant, malignant, libelous, mad.” The reader consulting a card catalogue in a library was living a revolution as momentous, and as disorienting, as our own.
  • The book index was the search engine of its era, and needed to be explained at length to puzzled researchers
  • That uniquely evil and necessary thing the comprehensive review of many different books on a related subject, with the necessary oversimplification of their ideas that it demanded, was already around in 1500, and already being accused of missing all the points. In the period when many of the big, classic books that we no longer have time to read were being written, the general complaint was that there wasn’t enough time to read big, classic books.
  • at any given moment, our most complicated machine will be taken as a model of human intelligence, and whatever media kids favor will be identified as the cause of our stupidity. When there were automatic looms, the mind was like an automatic loom; and, since young people in the loom period liked novels, it was the cheap novel that was degrading our minds. When there were telephone exchanges, the mind was like a telephone exchange, and, in the same period, since the nickelodeon reigned, moving pictures were making us dumb. When mainframe computers arrived and television was what kids liked, the mind was like a mainframe and television was the engine of our idiocy. Some machine is always showing us Mind; some entertainment derived from the machine is always showing us Non-Mind.

  • . Is it morally permissible to submit to total instrumentalization living beings that, though they do not have a central nervous system, are capable of basic learning and communication? Should their swift response to stress leave us coldly indifferent, while animal suffering provokes intense feelings of pity and compassion?
  • When it comes to a plant, it turns out to be not only a what but also a who — an agent in its milieu, with its own intrinsic value or version of the good. Inquiring into justifications for consuming vegetal beings thus reconceived, we reach one of the final frontiers of dietary ethics.

  • the subjectivity of plants is not centered in a single organ or function but is dispersed throughout their bodies, from the roots to the leaves and shoots. Nevertheless, this dispersion of vitality holds out a promise of its own: the plasticity of plants and their wondrous capacity for regeneration, their growth by increments, quantitative additions or reiterations of already existing parts does little to change the form of living beings that are neither parts nor wholes because they are not hierarchically structured organisms. The “renewable” aspects of perennial plants may be accepted by humans as a gift of vegetal being and integrated into their diets.
  • The desire to eat ethically is, perhaps, akin to this royal sensitivity, as some would argue that it is a luxury of those who do have enough food to select, in a conscious manner, their dietary patterns.
  • Weiye Loh on 29 Apr 12
     
    a pea plant subjected to drought conditions communicated its stress to other such plants, with which it shared its soil. In other words, through the roots, it relayed to its neighbors the biochemical message about the onset of drought, prompting them to react as though they, too, were in a similar predicament. Curiously, having received the signal, plants not directly affected by this particular environmental stress factor were better able to withstand adverse conditions when they actually occurred. This means that the recipients of biochemical communication could draw on their "memories" - information stored at the cellular level - to activate appropriate defenses and adaptive responses when the need arose.

    while I was watching this video, I suddenly had a desire to share this video with my friends. Then I realised that there are serious ethics issues here. Such is the life of a NM4204 student. 1. Is it alright to video a clip of a live performance? Seeing as I have just spent a couple of hundreds on a ticket, surely I am allowed to bring home some memories. Leaving uploading online aside, is the act of recording infringing on rights? Seeing as it does not harm either party if the clip is stroed in my device, and I viewed at my own time. 2. By us (me that is to say) sharing this file while everyone in the class, have I stepped into the boundaries of infringing on copyrights, seeing as the playback of this clip asynchronously can constitute as a public performance right? In any case, enjoy this song first before you think about these. One of my favourite artist.

Internet Polarisation

shared by Weiye Loh on 15 Aug 10 - Cached
  • American magazine the Atlantic lobs an intellectual grenade into our culture. In the summer of 1945, for example, it published an essay by the Massachusetts Institute of Technology (MIT) engineer Vannevar Bush entitled "As We May Think". It turned out to be the blueprint for what eventually emerged as the world wide web. Two summers ago, the Atlantic published an essay by Nicholas Carr, one of the blogosphere's most prominent (and thoughtful) contrarians, under the headline "Is Google Making Us Stupid?".
  • Carr wrote, "I've had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn't going – so far as I can tell – but it's changing. I'm not thinking the way I used to think. I can feel it most strongly when I'm reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument and I'd spend hours strolling through long stretches of prose. That's rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I'm always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle."
  • Carr's target was not really the world's leading search engine, but the impact that ubiquitous, always-on networking is having on our cognitive processes. His argument was that our deepening dependence on networking technology is indeed changing not only the way we think, but also the structure of our brains.
  • ...9 more annotations...
  • Carr's article touched a nerve and has provoked a lively, ongoing debate on the net and in print (he has now expanded it into a book, The Shallows: What the Internet Is Doing to Our Brains). This is partly because he's an engaging writer who has vividly articulated the unease that many adults feel about the way their modi operandi have changed in response to ubiquitous networking.
  • Who bothers to write down or memorise detailed information any more, for example, when they know that Google will always retrieve it if it's needed again? The web has become, in a way, a global prosthesis for our collective memory.
  • easy to dismiss Carr's concern as just the latest episode of the moral panic that always accompanies the arrival of a new communications technology. People fretted about printing, photography, the telephone and television in analogous ways. It even bothered Plato, who argued that the technology of writing would destroy the art of remembering.
  • many commentators who accept the thrust of his argument seem not only untroubled by its far-reaching implications but are positively enthusiastic about them. When the Pew Research Centre's Internet & American Life project asked its panel of more than 370 internet experts for their reaction, 81% of them agreed with the proposition that "people's use of the internet has enhanced human intelligence".
  • As a writer, thinker, researcher and teacher, what I can attest to is that the internet is changing our habits of thinking, which isn't the same thing as changing our brains. The brain is like any other muscle – if you don't stretch it, it gets both stiff and flabby. But if you exercise it regularly, and cross-train, your brain will be flexible, quick, strong and versatile.
  • he internet is analogous to a weight-training machine for the brain, as compared with the free weights provided by libraries and books. Each method has its advantage, but used properly one works you harder. Weight machines are directive and enabling: they encourage you to think you've worked hard without necessarily challenging yourself. The internet can be the same: it often tells us what we think we know, spreading misinformation and nonsense while it's at it. It can substitute surface for depth, imitation for originality, and its passion for recycling would surpass the most committed environmentalist.
  • I've seen students' thinking habits change dramatically: if information is not immediately available via a Google search, students are often stymied. But of course what a Google search provides is not the best, wisest or most accurate answer, but the most popular one.
  • But knowledge is not the same thing as information, and there is no question to my mind that the access to raw information provided by the internet is unparalleled and democratising. Admittance to elite private university libraries and archives is no longer required, as they increasingly digitise their archives. We've all read the jeremiads that the internet sounds the death knell of reading, but people read online constantly – we just call it surfing now. What they are reading is changing, often for the worse; but it is also true that the internet increasingly provides a treasure trove of rare books, documents and images, and as long as we have free access to it, then the internet can certainly be a force for education and wisdom, and not just for lies, damned lies, and false statistics.
  • In the end, the medium is not the message, and the internet is just a medium, a repository and an archive. Its greatest virtue is also its greatest weakness: it is unselective. This means that it is undiscriminating, in both senses of the word. It is indiscriminate in its principles of inclusion: anything at all can get into it. But it also – at least so far – doesn't discriminate against anyone with access to it. This is changing rapidly, of course, as corporations and governments seek to exert control over it. Knowledge may not be the same thing as power, but it is unquestionably a means to power. The question is, will we use the internet's power for good, or for evil? The jury is very much out. The internet itself is disinterested: but what we use it for is not.

  • astrobiologists, working with oncologists in the US, have suggested that cancer resembles ancient forms of life that flourished between 600 million and 1 billion years ago.
  • Read more about what this discovery means for cancer research.
  • The genes that controlled the behaviour of these early multicellular organisms still reside within our own cells, managed by more recent genes that keep them in check.It's when these newer controlling genes fail that the older mechanisms take over, and the cell reverts to its earlier behaviours and grows out of control.
  • ...11 more annotations...
  • The new theory, published in the journal Physical Biology, has been put forward by two leading figures in the world of cosmology and astrobiology: Paul Davies, director of the Beyond Center for Fundamental Concepts in Science, Arizona State University; and Charles Lineweaver, from the Australian National University.
  • According to Lineweaver, this suggests that cancer is an atavism, or an evolutionary throwback.
  • In the paper, they suggest that a close look at cancer shows similarities with early forms of multicellular life.
  • “Unlike bacteria and viruses, cancer has not developed the capacity to evolve into new forms. In fact, cancer is better understood as the reversion of cells to the way they behaved a little over one billion years ago, when humans were nothing more than loose-knit colonies of only partially differentiated cells. “We think that the tumours that develop in cancer patients today take the same form as these simple cellular structures did more than a billion years ago,” he said.
  • One piece of evidence to support this theory is that cancers appear in virtually all metazoans, with the notable exception of the bizarre naked mole rat."This quasi-ubiquity suggests that the mechanisms of cancer are deep-rooted in evolutionary history, a conjecture that receives support from both paleontology and genetics," they write.
  • the genes that controlled this early multi-cellular form of life are like a computer operating system's 'safe mode', and when there are failures or mutations in the more recent genes that manage the way cells specialise and interact to form the complex life of today, then the earlier level of programming takes over.
  • Their notion is in contrast to a prevailing theory that cancer cells are 'rogue' cells that evolve rapidly within the body, overcoming the normal slew of cellular defences.
  • However, Davies and Lineweaver point out that cancer cells are highly cooperative with each other, if competing with the host's cells. This suggests a pre-existing complexity that is reminiscent of early multicellular life.
  • cancers' manifold survival mechanisms are predictable, and unlikely to emerge spontaneously through evolution within each individual in such a consistent way.
  • The good news is that this means combating cancer is not necessarily as complex as if the cancers were rogue cells evolving new and novel defence mechanisms within the body.Instead, because cancers fall back on the same evolved mechanisms that were used by early life, we can expect them to remain predictable, thus if they're susceptible to treatment, it's unlikely they'll evolve new ways to get around it.
  • If the atavism hypothesis is correct, there are new reasons for optimism," they write.

    The environmental movement has a strange historical relationship with nuclear power. In many countries, opposition to nuclear reactors in the wake of Chernobyl gave rise to major Green political parties. Many environmentalists still oppose nuclear power--Greenpeace, for example, still calls for the phase out of all reactors. But as climate change has taken over the Green agenda, other environmentalists have come to favor nuclear  as part of a low-carbon energy mix.  It was this confluence of factors-fading memories of Chernobyl and increased concern about greenhouse gases--that gave the nuclear industry such confidence just a few years ago. That confidence will have been deeply shaken by events in Japan.

Religion Immortality Transhumanism Scientism Bioethics

shared by Weiye Loh on 19 Apr 11 - No Cached
  • There is something almost religious about Kurzweil’s scientism, an observation he himself makes in the film, noting the similarities between his goals and that of the world’s religions: “the idea of a profound transformation in the future, eternal life, bringing back the dead—but the fact that we’re applying technology to achieve the goals that have been talked about in all human philosophies is not accidental because it does reflect the goal of humanity.” Although the film never discloses Kurzweil’s religious beliefs (he was raised by Jewish parents as a Unitarian Universalist), in a (presumably) unintentionally humorous moment that ends the film Kurzweil reflects on the God question and answers it himself: “Does God exist? I would say, ‘Not yet.’”
  • Transcendent Man is Barry Ptolemy’s beautifully crafted and artfully edited documentary film about Kurzweil and his quest to save humanity.
  • Transcendent Man pulls viewers in through Kurzweil’s visage of a future in which we merge with our machines and vastly extend our longevity and intelligence to the point where even death will be defeated. This point is what Kurzweil calls the “singularity” (inspired by the physics term denoting the infinitely dense point at the center of a black hole), and he arrives at the 2029 date by extrapolating curves based on what he calls the “law of accelerating returns.” This is “Moore’s Law” (the doubling of computing power every year) on steroids, applied to every conceivable area of science, technology and economics.
  • ...6 more annotations...
  • Ptolemy’s portrayal of Kurzweil is unmistakably positive, but to his credit he includes several critics from both religion and science. From the former, a radio host named Chuck Missler, a born-again Christian who heads the Koinonia Institute (“dedicated to training and equipping the serious Christian to sojourn in today’s world”), proclaims: “We have a scenario laid out that the world is heading for an Armageddon and you and I are going to be the generation that’s alive that is going to see all this unfold.” He seems to be saying that Kurzweil is right about the second coming, but wrong about what it is that is coming. (Of course, Missler’s prognostication is the N+1 failed prophecy that began with Jesus himself, who told his followers (Mark 9:1): “Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.”) Another religiously-based admonition comes from the Stanford University neuroscientist William Huribut, who self-identifies as a “practicing Christian” who believes in immortality, but not in the way Kurzweil envisions it. “Death is conquered spiritually,” he pronounced.
  • On the science side of the ledger, Neil Gershenfeld, director of the Center for Bits and Atoms at the Massachusetts Institute of Technology, sagely notes: “What Ray does consistently is to take a whole bunch of steps that everybody agrees on and take principles for extrapolating that everybody agrees on and show they lead to things that nobody agrees on.” Likewise, the estimable futurist Kevin Kelly, whose 2010 book What Technology Wants paints a much more realistic portrait of what our futures may (or may not) hold
  • Kelly agrees that Kurzweil’s exponential growth curves are accurate but that the conclusions and especially the inspiration drawn from them are not. “He seems to have no doubts about it and in this sense I think he is a prophetic type figure who is completely sure and nothing can waiver his absolute certainty about this. So I would say he is a modern day prophet…that’s wrong.”
  • Transcendent Man is clearly meant to be an uplifting film celebrating all the ways science and technology have and are going to enrich our lives.
  • An especially lachrymose moment is when Kurzweil is rifling through his father’s journals and documents in a storage room dedicated to preserving his memory until the day that all this “data” (including Ray’s own fading memories) can be reconfigured into an A.I. simulacrum so that father and son can be reunited.
  • Although Kurzweil says he is optimistic and cheery about life, he can’t seem to stop talking about death: “It’s such a profoundly sad, lonely feeling that I really can’t bear it,” he admits. “So I go back to thinking about how I’m not going to die.” One wonders how much of life he is missing by over thinking death, or how burdensome it must surely be to imbibe over 200 supplement tables a day and have your blood tested and cleansed every couple of months, all in an effort to reprogram the body’s biochemistry.

Evolution Rationality

shared by Weiye Loh on 18 Aug 10 - Cached
  • The reason we succumb to confirmation bias, why we are blind to counterexamples, and why we fall short of CartesianCartesian logic in so many other ways is that these lapses have a purpose: they help us “devise and evaluate arguments that are intended to persuade other people,” says psychologist Hugo Mercier of the University of Pennsylvania. Failures of logic, he and cognitive scientist Dan Sperber of the Institut Jean Nicod in Paris propose, are in fact effective ploys to win arguments.
  • That puts poor reasoning in a completely different light. Arguing, after all, is less about seeking truth than about overcoming opposing views.
  • while confirmation bias, for instance, may mislead us about what’s true and real, by letting examples that support our view monopolize our memory and perception, it maximizes the artillery we wield when trying to convince someone that, say, he really is “late all the time.” Confirmation bias “has a straightforward explanation,” argues Mercier. “It contributes to effective argumentation.”
  • ...2 more annotations...
  • finding counterexamples can, in general, weaken our confidence in our own arguments. Forms of reasoning that are good for solving logic puzzles but bad for winning arguments lost out, over the course of evolution, to those that help us be persuasive but cause us to struggle with abstract syllogisms. Interestingly, syllogisms are easier to evaluate in the form “No flying things are penguins; all penguins are birds; so some birds are not fliers.” That’s because we are more likely to argue about animals than A, B, and C.
  • The sort of faulty thinking called motivated reasoning also impedes our search for truth but advances arguments. For instance, we tend to look harder for flaws in a study when we don’t agree with its conclusions and are more critical of evidence that undermines our point of view.

Free Trade Innovation Copyright Patent

shared by Weiye Loh on 04 Sep 10 - Cached
  • In terms of processing power, speed, memory, and so on, how do Macs and PCs actually compare? And does Apple innovate in terms of basic hardware quality as often or less often than the likes of HP, Compaq, and other producers? This question is of broader interest from an economist's point of view because it also has to do with the age-old question of whether competition or monopoly is a better spur to innovation. In a certain sense, Apple is a monopolist, and PC makers are in a more competitive market. (I say in a certain sense because obviously Macs and PCs are substitutes; it's just that they're more imperfect substitutes than two PCs are for each other, in part because of software migration issues.)
  • Schumpeter argued long back that because a monopolist reaps the full reward from innovation, such firms would be more innovative. The case for patents relies in part on a version of this argument: companies are given monopoly rights over a new product for a period of time in order for them to be able to recoup the costs of innovation; without such protection, it is argued, they would not find it beneficial to innovate in the first place.
  • others have argued that competition spurs innovation by giving firms a way to differentiate themselves from their competitors (in a way, creating something new gives a company a temporary, albeit brief, "monopoly")

  • Few devices know more personal details about people than the smartphones in their pockets: phone numbers, current location, often the owner's real name—even a unique ID number that can never be changed or turned off.
  • An examination of 101 popular smartphone "apps"—games and other software applications for iPhone and Android phones—showed that 56 transmitted the phone's unique device ID to other companies without users' awareness or consent. Forty-seven apps transmitted the phone's location in some way. Five sent age, gender and other personal details to outsiders.
  • The findings reveal the intrusive effort by online-tracking companies to gather personal data about people in order to flesh out detailed dossiers on them.
  • ...24 more annotations...
  • iPhone apps transmitted more data than the apps on phones using Google Inc.'s Android operating system. Because of the test's size, it's not known if the pattern holds among the hundreds of thousands of apps available.
  • TextPlus 4, a popular iPhone app for text messaging. It sent the phone's unique ID number to eight ad companies and the phone's zip code, along with the user's age and gender, to two of them.
  • Pandora, a popular music app, sent age, gender, location and phone identifiers to various ad networks. iPhone and Android versions of a game called Paper Toss—players try to throw paper wads into a trash can—each sent the phone's ID number to at least five ad companies. Grindr, an iPhone app for meeting gay men, sent gender, location and phone ID to three ad companies.
  • iPhone maker Apple Inc. says it reviews each app before offering it to users. Both Apple and Google say they protect users by requiring apps to obtain permission before revealing certain kinds of information, such as location.
  • The Journal found that these rules can be skirted. One iPhone app, Pumpkin Maker (a pumpkin-carving game), transmits location to an ad network without asking permission. Apple declines to comment on whether the app violated its rules.
  • With few exceptions, app users can't "opt out" of phone tracking, as is possible, in limited form, on regular computers. On computers it is also possible to block or delete "cookies," which are tiny tracking files. These techniques generally don't work on cellphone apps.
  • makers of TextPlus 4, Pandora and Grindr say the data they pass on to outside firms isn't linked to an individual's name. Personal details such as age and gender are volunteered by users, they say. The maker of Pumpkin Maker says he didn't know Apple required apps to seek user approval before transmitting location. The maker of Paper Toss didn't respond to requests for comment.
  • Many apps don't offer even a basic form of consumer protection: written privacy policies. Forty-five of the 101 apps didn't provide privacy policies on their websites or inside the apps at the time of testing. Neither Apple nor Google requires app privacy policies.
  • the most widely shared detail was the unique ID number assigned to every phone.
  • On iPhones, this number is the "UDID," or Unique Device Identifier. Android IDs go by other names. These IDs are set by phone makers, carriers or makers of the operating system, and typically can't be blocked or deleted. "The great thing about mobile is you can't clear a UDID like you can a cookie," says Meghan O'Holleran of Traffic Marketplace, an Internet ad network that is expanding into mobile apps. "That's how we track everything."
  • O'Holleran says Traffic Marketplace, a unit of Epic Media Group, monitors smartphone users whenever it can. "We watch what apps you download, how frequently you use them, how much time you spend on them, how deep into the app you go," she says. She says the data is aggregated and not linked to an individual.
  • Apple and Google ad networks let advertisers target groups of users. Both companies say they don't track individuals based on the way they use apps.
  • Apple limits what can be installed on an iPhone by requiring iPhone apps to be offered exclusively through its App Store. Apple reviews those apps for function, offensiveness and other criteria.
  • Apple says iPhone apps "cannot transmit data about a user without obtaining the user's prior permission and providing the user with access to information about how and where the data will be used." Many apps tested by the Journal appeared to violate that rule, by sending a user's location to ad networks, without informing users. Apple declines to discuss how it interprets or enforces the policy.
  • Google doesn't review the apps, which can be downloaded from many vendors. Google says app makers "bear the responsibility for how they handle user information." Google requires Android apps to notify users, before they download the app, of the data sources the app intends to access. Possible sources include the phone's camera, memory, contact list, and more than 100 others. If users don't like what a particular app wants to access, they can choose not to install the app, Google says.
  • Neither Apple nor Google requires apps to ask permission to access some forms of the device ID, or to send it to outsiders. When smartphone users let an app see their location, apps generally don't disclose if they will pass the location to ad companies.
  • Lack of standard practices means different companies treat the same information differently. For example, Apple says that, internally, it treats the iPhone's UDID as "personally identifiable information." That's because, Apple says, it can be combined with other personal details about people—such as names or email addresses—that Apple has via the App Store or its iTunes music services. By contrast, Google and most app makers don't consider device IDs to be identifying information.
  • A growing industry is assembling this data into profiles of cellphone users. Mobclix, the ad exchange, matches more than 25 ad networks with some 15,000 apps seeking advertisers. The Palo Alto, Calif., company collects phone IDs, encodes them (to obscure the number), and assigns them to interest categories based on what apps people download and how much time they spend using an app, among other factors. By tracking a phone's location, Mobclix also makes a "best guess" of where a person lives, says Mr. Gurbuxani, the Mobclix executive. Mobclix then matches that location with spending and demographic data from Nielsen Co.
  • Mobclix can place a user in one of 150 "segments" it offers to advertisers, from "green enthusiasts" to "soccer moms." For example, "die hard gamers" are 15-to-25-year-old males with more than 20 apps on their phones who use an app for more than 20 minutes at a time. Mobclix says its system is powerful, but that its categories are broad enough to not identify individuals. "It's about how you track people better," Mr. Gurbuxani says.
  • four app makers posted privacy policies after being contacted by the Journal, including Rovio Mobile Ltd., the Finnish company behind the popular game Angry Birds (in which birds battle egg-snatching pigs). A spokesman says Rovio had been working on the policy, and the Journal inquiry made it a good time to unveil it.
  • Free and paid versions of Angry Birds were tested on an iPhone. The apps sent the phone's UDID and location to the Chillingo unit of Electronic Arts Inc., which markets the games. Chillingo says it doesn't use the information for advertising and doesn't share it with outsiders.
  • Some developers feel pressure to release more data about people. Max Binshtok, creator of the DailyHoroscope Android app, says ad-network executives encouraged him to transmit users' locations. Mr. Binshtok says he declined because of privacy concerns. But ads targeted by location bring in two to five times as much money as untargeted ads, Mr. Binshtok says. "We are losing a lot of revenue."
  • Apple targets ads to phone users based largely on what it knows about them through its App Store and iTunes music service. The targeting criteria can include the types of songs, videos and apps a person downloads, according to an Apple ad presentation reviewed by the Journal. The presentation named 103 targeting categories, including: karaoke, Christian/gospel music, anime, business news, health apps, games and horror movies. People familiar with iAd say Apple doesn't track what users do inside apps and offers advertisers broad categories of people, not specific individuals. Apple has signaled that it has ideas for targeting people more closely. In a patent application filed this past May, Apple outlined a system for placing and pricing ads based on a person's "web history or search history" and "the contents of a media library." For example, home-improvement advertisers might pay more to reach a person who downloaded do-it-yourself TV shows, the document says.
  • The patent application also lists another possible way to target people with ads: the contents of a friend's media library. How would Apple learn who a cellphone user's friends are, and what kinds of media they prefer? The patent says Apple could tap "known connections on one or more social-networking websites" or "publicly available information or private databases describing purchasing decisions, brand preferences," and other data. In September, Apple introduced a social-networking service within iTunes, called Ping, that lets users share music preferences with friends. Apple declined to comment.

Reading Internet Thinking

shared by Weiye Loh on 03 Mar 11 - No Cached
  • There are two ways that computers might add to our wellbeing. First, they could do so indirectly, by increasing our ability to produce other goods and services. In this they have proved something of a disappointment. In the early 1970s, American businesses began to invest heavily in computer hardware and software, but for decades this enormous investment seemed to pay no dividends. As the economist Robert Solow put it in 1987, ‘You can see the computer age everywhere but in the productivity statistics.’ Perhaps too much time was wasted in training employees to use computers; perhaps the sorts of activity that computers make more efficient, like word processing, don’t really add all that much to productivity; perhaps information becomes less valuable when it’s more widely available. Whatever the case, it wasn’t until the late 1990s that some of the productivity gains promised by the computer-driven ‘new economy’ began to show up – in the United States, at any rate. So far, Europe appears to have missed out on them.
  • The other way computers could benefit us is more direct. They might make us smarter, or even happier. They promise to bring us such primary goods as pleasure, friendship, sex and knowledge. If some lotus-eating visionaries are to be believed, computers may even have a spiritual dimension: as they grow ever more powerful, they have the potential to become our ‘mind children’. At some point – the ‘singularity’ – in the not-so-distant future, we humans will merge with these silicon creatures, thereby transcending our biology and achieving immortality. It is all of this that Woody Allen is missing out on.
  • But there are also sceptics who maintain that computers are having the opposite effect on us: they are making us less happy, and perhaps even stupider. Among the first to raise this possibility was the American literary critic Sven Birkerts. In his book The Gutenberg Elegies (1994), Birkerts argued that the computer and other electronic media were destroying our capacity for ‘deep reading’. His writing students, thanks to their digital devices, had become mere skimmers and scanners and scrollers. They couldn’t lose themselves in a novel the way he could. This didn’t bode well, Birkerts thought, for the future of literary culture.

  • Suppose we found that computers are diminishing our capacity for certain pleasures, or making us worse off in other ways. Why couldn’t we simply spend less time in front of the screen and more time doing the things we used to do before computers came along – like burying our noses in novels? Well, it may be that computers are affecting us in a more insidious fashion than we realise. They may be reshaping our brains – and not for the better. That was the drift of ‘Is Google Making Us Stupid?’, a 2008 cover story by Nicholas Carr in the Atlantic.
  • Carr thinks that he was himself an unwitting victim of the computer’s mind-altering powers. Now in his early fifties, he describes his life as a ‘two-act play’, ‘Analogue Youth’ followed by ‘Digital Adulthood’. In 1986, five years out of college, he dismayed his wife by spending nearly all their savings on an early version of the Apple Mac. Soon afterwards, he says, he lost the ability to edit or revise on paper. Around 1990, he acquired a modem and an AOL subscription, which entitled him to spend five hours a week online sending email, visiting ‘chat rooms’ and reading old newspaper articles. It was around this time that the programmer Tim Berners-Lee wrote the code for the World Wide Web, which, in due course, Carr would be restlessly exploring with the aid of his new Netscape browser.
  • Carr launches into a brief history of brain science, which culminates in a discussion of ‘neuroplasticity’: the idea that experience affects the structure of the brain. Scientific orthodoxy used to hold that the adult brain was fixed and immutable: experience could alter the strengths of the connections among its neurons, it was believed, but not its overall architecture. By the late 1960s, however, striking evidence of brain plasticity began to emerge. In one series of experiments, researchers cut nerves in the hands of monkeys, and then, using microelectrode probes, observed that the monkeys’ brains reorganised themselves to compensate for the peripheral damage. Later, tests on people who had lost an arm or a leg revealed something similar: the brain areas that used to receive sensory input from the lost limbs seemed to get taken over by circuits that register sensations from other parts of the body (which may account for the ‘phantom limb’ phenomenon). Signs of brain plasticity have been observed in healthy people, too. Violinists, for instance, tend to have larger cortical areas devoted to processing signals from their fingering hands than do non-violinists. And brain scans of London cab drivers taken in the 1990s revealed that they had larger than normal posterior hippocampuses – a part of the brain that stores spatial representations – and that the increase in size was proportional to the number of years they had been in the job.
  • The brain’s ability to change its own structure, as Carr sees it, is nothing less than ‘a loophole for free thought and free will’. But, he hastens to add, ‘bad habits can be ingrained in our neurons as easily as good ones.’ Indeed, neuroplasticity has been invoked to explain depression, tinnitus, pornography addiction and masochistic self-mutilation (this last is supposedly a result of pain pathways getting rewired to the brain’s pleasure centres). Once new neural circuits become established in our brains, they demand to be fed, and they can hijack brain areas devoted to valuable mental skills. Thus, Carr writes: ‘The possibility of intellectual decay is inherent in the malleability of our brains.’ And the internet ‘delivers precisely the kind of sensory and cognitive stimuli – repetitive, intensive, interactive, addictive – that have been shown to result in strong and rapid alterations in brain circuits and functions’. He quotes the brain scientist Michael Merzenich, a pioneer of neuroplasticity and the man behind the monkey experiments in the 1960s, to the effect that the brain can be ‘massively remodelled’ by exposure to the internet and online tools like Google. ‘THEIR HEAVY USE HAS NEUROLOGICAL CONSEQUENCES,’ Merzenich warns in caps – in a blog post, no less.
  • It’s not that the web is making us less intelligent; if anything, the evidence suggests it sharpens more cognitive skills than it dulls. It’s not that the web is making us less happy, although there are certainly those who, like Carr, feel enslaved by its rhythms and cheated by the quality of its pleasures. It’s that the web may be an enemy of creativity. Which is why Woody Allen might be wise in avoiding it altogether.
  • empirical support for Carr’s conclusion is both slim and equivocal. To begin with, there is evidence that web surfing can increase the capacity of working memory. And while some studies have indeed shown that ‘hypertexts’ impede retention – in a 2001 Canadian study, for instance, people who read a version of Elizabeth Bowen’s story ‘The Demon Lover’ festooned with clickable links took longer and reported more confusion about the plot than did those who read it in an old-fashioned ‘linear’ text – others have failed to substantiate this claim. No study has shown that internet use degrades the ability to learn from a book, though that doesn’t stop people feeling that this is so – one medical blogger quoted by Carr laments, ‘I can’t read War and Peace any more.’

Homeopathy Science Medicine Health News

shared by Weiye Loh on 22 Feb 11 - No Cached
  • The 10:23 demonstrations and the CBC Marketplace coverage have elicited fascinating case studies in CAM professionalism. Rather than offering any new information or evidence about homeopathy itself, some homeopaths have spuriously accused skeptical groups of being malicious Big Pharma shills.
  • Mike Adams of the Natural News website
  • has decided to provide his own coverage of the 10:23 campaign
  • ...17 more annotations...
  • Mike’s thesis is essentially: Silly skeptics, it’s impossible to OD on homeopathy!
  • 1. “Notice that they never consume their own medicines in large doses? Chemotherapy? Statin drugs? Blood thinners? They wouldn’t dare drink those.
  • Of course we wouldn’t. Steven Novella rightly points out that, though Mike thinks he’s being clever here, he’s actually demonstrating a lack of understanding for what the 10:23 campaign is about by using a straw man. Mike later issues a challenge for skeptics to drink their favourite medicines while he drinks homeopathy. Since no one will agree to that for the reasons explained above, he can claim some sort of victory — hence his smugness. But no one is saying that drugs aren’t harmful.
  • The difference between medicine and poison is in the dose. The vitamins and herbs promoted by the CAM industry are just as potentially harmful as any pharmaceutical drug, given enough of it. Would Adams be willing to OD on the vitamins or herbal remedies that he sells?
  • Even Adams’ favorite panacea, vitamin D, is toxic if you take enough of it (just ask Gary Null). Notice how skeptics don’t consume those either, because that is not the point they’re making.
  • The point of these demonstrations is that homeopathy has nothing in it, has no measurable physiological effects, and does not do what is advertised on the package.
  • 2. “Homeopathy, you see, isn’t a drug. It’s not a chemical.” Well, he’s got that right. “You know the drugs are kicking in when you start getting worse. Toxicity and conventional medicine go hand in hand.” [emphasis his]
  • Here I have to wonder if Adams knows any people with diabetes, AIDS, or any other illness that used to mean a death sentence before the significant medical advances of the 20th century that we now take for granted. So far he seems to be a firm believer in the false dichotomy that drugs are bad and natural products are good, regardless of what’s in them or how they’re used (as we know, natural products can have biologically active substances and effectively act as impure drugs – but leave it to Adams not to get bogged down with details). There is nothing to support the assertion that conventional medicine is nothing but toxic symptom-inducers.
  • 3-11. “But homeopathy isn’t a chemical. It’s a resonance. A vibration, or a harmony. It’s the restructuring of water to resonate with the particular energy of a plant or substance. We can get into the physics of it in a subsequent article, but for now it’s easy to recognize that even from a conventional physics point of view, liquid water has tremendous energy, and it’s constantly in motion, not just at the molecular level but also at the level of its subatomic particles and so-called “orbiting electrons” which aren’t even orbiting in the first place. Electrons are vibrations and not physical objects.” [emphasis his]
  • This is Star Trek-like technobabble – lots of sciency words
  • if something — anything — has an effect, then that effect is measurable by definition. Either something works or it doesn’t, regardless of mechanism. In any case, I’d like to see the well-documented series of research that conclusively proves this supposed mechanism. Actually, I’d like to see any credible research at all. I know what the answer will be to that: science can’t detect this yet. Well if you agree with that statement, reader, ask yourself this: then how does Adams know? Where did he get this information? Without evidence, he is guessing, and what is that really worth?
  • 13. “But getting back to water and vibrations, which isn’t magic but rather vibrational physics, you can’t overdose on a harmony. If you have one violin playing a note in your room, and you add ten more violins — or a hundred more — it’s all still the same harmony (with all its complex higher frequencies, too). There’s no toxicity to it.” [emphasis his]
  • Homeopathy has standard dosing regimes (they’re all the same), but there is no “dose” to speak of: the ingredients have usually been diluted out to nothing. But Adams is also saying that homeopathy doesn’t work by dose at all, it works by the properties of “resonance” and “vibration”. Then why any dosing regimen? To maintain the resonance? How is this resonance measured? How long does the “resonance” last? Why does it wear off? Why does he think televisions can inactivate homeopathy? (I think I might know the answer to that last one, as electronic interference is a handy excuse for inefficacy.)
  • “These skeptics just want to kill themselves… and they wouldn’t mind taking a few of you along with them, too. Hence their promotion of vaccines, pharmaceuticals, chemotherapy and water fluoridation. We’ll title the video, “SKEPTICS COMMIT MASS SUICIDE BY DRINKING PHARMACEUTICALS AS IF THEY WERE KOOL-AID.” Jonestown, anyone?”
  • “Do you notice the irony here? The only medicines they’re willing to consume in large doses in public are homeopathic remedies! They won’t dare consume large quantities of the medicines they all say YOU should be taking! (The pharma drugs.)” [emphasis his]
  • what Adams seems to have missed is that the skeptics have no intention of killing themselves, so his bizarre claims that the 10:23 participants are psychopathic, self-loathing, and suicidal makes not even a little bit of sense. Skeptics know they aren’t going to die with these demonstrations, because homeopathy has no active ingredients and no evidence of efficacy.
  • The inventor of homeopathy himself, Samuel Hahnemann believed that excessive doses of homeopathy could be harmful (see sections 275 and 276 of his Organon). Homeopaths are pros at retconning their own field to fit in with Hahnemann’s original ideas (inventing new mechanisms, such as water memory and resonance, in the face of germ theory). So how does Adams reconcile this claim?
