Introduction: The Human Brain - life - 04 September 2006 - New Scientist - 0 views

  • The brain is the most complex organ in the human body
  • It is in these changing connections that memories are stored, habits learned and personalities shaped, by reinforcing certain patterns of brain activity, and losing others.
  • While people often speak of their "grey matter", the brain also contains white matter. The grey matter is the cell bodies of the neurons, while the white matter is the branching network of thread-like tendrils - called dendrites and axons - that spread out from the cell bodies to connect to other neurons.

  • The brain has bursts of growth and then periods of consolidation, when excess connections are pruned. The most notable bursts are in the first two or three years of life, during puberty, and also a final burst in young adulthood.
  • t is the most evolutionarily recent brain structure, dealing with more complex cognitive brain activities.

MSNBC, Its Ratings Rising, Gains Ground on Fox News - NYTimes.com - 0 views

  • During Mr. Obama’s first term, MSNBC underwent a metamorphosis from a CNN also-ran to the anti-Fox, and handily beat CNN in the ratings along the way. Now that it is known, at least to those who cannot get enough politics, as the nation’s liberal television network, the challenge in the next four years will be to capitalize on that identity.
  • MSNBC, a unit of NBCUniversal, has a long way to go to overtake the Fox News Channel, a unit of News Corporation: on most nights this year, Fox had two million more viewers than MSNBC. But the two channels, which skew toward an audience that is 55 or older, are on average separated by fewer than 300,000 viewers in the 25- to 54-year-old demographic that advertisers desire. On three nights in a row after the election last week, MSNBC — whose hosts reveled in Mr. Obama’s victory — had more viewers than Fox in that demographic.
  • MSNBC sees itself as the voice of Mr. Obama’s America.

  • MSNBC, which until 2005 was partly owned by Microsoft, is where Fox was a decade ago — in the early stages of profiting from its popularity. The channel receives a per-subscriber fee of 30 cents a month from cable operators; CNN receives twice that, and Fox News at least three times as much.
  • Many progressives (and conservatives) now view the channel as a megaphone for liberal politicians, ideas and attacks against those who disagree. Such a megaphone — clearly marked, always on — has never existed before on television.
  • It has all happened rather suddenly. During the presidential election in 2008, Ms. Maddow was so new that she was still getting lost in the labyrinth of Rockefeller Center. And MSNBC was so timid about applying a political point of view that it paired an NBC News anchor, David Gregory, with the outspoken Mr. Olbermann on election nigh
  • Fears among some MSNBC viewers that Comcast would water down the channel’s liberal streak have not come to pass. Of MSNBC, former President Bill Clinton remarked last winter, “Boy, it really has become our version of Fox.”
  • Any comparison of the two channels is colored by charges of false equivalencies — “I think that we are more information-based,” Ms. Maddow has said — and reminders that Fox is far more popular.

A Super-Simple Way to Understand the Net Neutrality Debate - NYTimes.com - 0 views

  • there is a really simple way of thinking of the debate over net neutrality: Is access to the Internet more like access to electricity, or more like cable television service?
  • For all the technical complexity of generating electricity and distributing it to millions of people, the economic arrangement is very simple: I give them money. They give me electricity. I do with it what I will.
  • One theory of the case, and the one that the Obama administration embraced Monday, is that the Internet is like electricity. It is fundamental to the 21st century economy, as essential to functioning in modern society as electricity. It is a public utility. “We cannot allow Internet service providers (ISPs) to restrict the best access or to pick winners and losers in the online marketplace for services and ideas,” the president said in his written statement.

  • Comcast, my cable provider, offers me a menu of packages from which I might choose, each with a different mix of channels. It goes through long and sometimes arduous negotiations with the owners of those cable channels and has a different business arrangement with each of them. The details of those arrangements are opaque to me as the consumer; all I know is that I can get the movie package for X dollars a month or the sports package for Y dollars and so on.
  • just as your electric utility has no say in how you use the electricity they sell you, the Internet should be a reliable way to access content produced by anyone, regardless of whether they have any special business arrangement with the utility.
  • Those arguing against net neutrality, most significantly the cable companies, say the Internet will be a richer experience if the profit motive applies, if they can negotiate deals with major content providers (the equivalent of cable channels) so that Netflix or Hulu or other streaming services that use huge bandwidth have to pay for the privilege.
  • It would also give your Internet provider considerably more economic leverage. It would, in the non-net-neutrality world, be free to throttle the speed with which you could access services that don’t pay up, or block sites entirely, as surely as you cannot watch a cable channel that your cable provider chooses not to offer (perhaps because of a dispute with the channel over fees).

How Does Science Really Work? | The New Yorker - 1 views

  • I wanted to be a scientist. So why did I find the actual work of science so boring? In college science courses, I had occasional bursts of mind-expanding insight. For the most part, though, I was tortured by drudgery.
  • I’d found that science was two-faced: simultaneously thrilling and tedious, all-encompassing and narrow. And yet this was clearly an asset, not a flaw. Something about that combination had changed the world completely.
  • “Science is an alien thought form,” he writes; that’s why so many civilizations rose and fell before it was invented. In his view, we downplay its weirdness, perhaps because its success is so fundamental to our continued existence.
  • ...50 more annotations...
  • In school, one learns about “the scientific method”—usually a straightforward set of steps, along the lines of “ask a question, propose a hypothesis, perform an experiment, analyze the results.”
  • That method works in the classroom, where students are basically told what questions to pursue. But real scientists must come up with their own questions, finding new routes through a much vaster landscape.
  • Since science began, there has been disagreement about how those routes are charted. Two twentieth-century philosophers of science, Karl Popper and Thomas Kuhn, are widely held to have offered the best accounts of this process.
  • For Popper, Strevens writes, “scientific inquiry is essentially a process of disproof, and scientists are the disprovers, the debunkers, the destroyers.” Kuhn’s scientists, by contrast, are faddish true believers who promulgate received wisdom until they are forced to attempt a “paradigm shift”—a painful rethinking of their basic assumptions.
  • Working scientists tend to prefer Popper to Kuhn. But Strevens thinks that both theorists failed to capture what makes science historically distinctive and singularly effective.
  • Sometimes they seek to falsify theories, sometimes to prove them; sometimes they’re informed by preëxisting or contextual views, and at other times they try to rule narrowly, based on t
  • Why do scientists agree to this scheme? Why do some of the world’s most intelligent people sign on for a lifetime of pipetting?
  • Strevens thinks that they do it because they have no choice. They are constrained by a central regulation that governs science, which he calls the “iron rule of explanation.” The rule is simple: it tells scientists that, “if they are to participate in the scientific enterprise, they must uncover or generate new evidence to argue with”; from there, they must “conduct all disputes with reference to empirical evidence alone.”
  • , it is “the key to science’s success,” because it “channels hope, anger, envy, ambition, resentment—all the fires fuming in the human heart—to one end: the production of empirical evidence.”
  • Strevens arrives at the idea of the iron rule in a Popperian way: by disproving the other theories about how scientific knowledge is created.
  • The problem isn’t that Popper and Kuhn are completely wrong. It’s that scientists, as a group, don’t pursue any single intellectual strategy consistently.
  • Exploring a number of case studies—including the controversies over continental drift, spontaneous generation, and the theory of relativity—Strevens shows scientists exerting themselves intellectually in a variety of ways, as smart, ambitious people usually do.
  • “Science is boring,” Strevens writes. “Readers of popular science see the 1 percent: the intriguing phenomena, the provocative theories, the dramatic experimental refutations or verifications.” But, he says,behind these achievements . . . are long hours, days, months of tedious laboratory labor. The single greatest obstacle to successful science is the difficulty of persuading brilliant minds to give up the intellectual pleasures of continual speculation and debate, theorizing and arguing, and to turn instead to a life consisting almost entirely of the production of experimental data.
  • Ultimately, in fact, it was good that the geologists had a “splendid variety” of somewhat arbitrary opinions: progress in science requires partisans, because only they have “the motivation to perform years or even decades of necessary experimental work.” It’s just that these partisans must channel their energies into empirical observation. The iron rule, Strevens writes, “has a valuable by-product, and that by-product is data.”
  • Science is often described as “self-correcting”: it’s said that bad data and wrong conclusions are rooted out by other scientists, who present contrary findings. But Strevens thinks that the iron rule is often more important than overt correction.
  • Eddington was never really refuted. Other astronomers, driven by the iron rule, were already planning their own studies, and “the great preponderance of the resulting measurements fit Einsteinian physics better than Newtonian physics.” It’s partly by generating data on such a vast scale, Strevens argues, that the iron rule can power science’s knowledge machine: “Opinions converge not because bad data is corrected but because it is swamped.”
  • Why did the iron rule emerge when it did? Strevens takes us back to the Thirty Years’ War, which concluded with the Peace of Westphalia, in 1648. The war weakened religious loyalties and strengthened national ones.
  • Two regimes arose: in the spiritual realm, the will of God held sway, while in the civic one the decrees of the state were paramount. As Isaac Newton wrote, “The laws of God & the laws of man are to be kept distinct.” These new, “nonoverlapping spheres of obligation,” Strevens argues, were what made it possible to imagine the iron rule. The rule simply proposed the creation of a third sphere: in addition to God and state, there would now be science.
  • Strevens imagines how, to someone in Descartes’s time, the iron rule would have seemed “unreasonably closed-minded.” Since ancient Greece, it had been obvious that the best thinking was cross-disciplinary, capable of knitting together “poetry, music, drama, philosophy, democracy, mathematics,” and other elevating human disciplines.
  • We’re still accustomed to the idea that a truly flourishing intellect is a well-rounded one. And, by this standard, Strevens says, the iron rule looks like “an irrational way to inquire into the underlying structure of things”; it seems to demand the upsetting “suppression of human nature.”
  • Descartes, in short, would have had good reasons for resisting a law that narrowed the grounds of disputation, or that encouraged what Strevens describes as “doing rather than thinking.”
  • In fact, the iron rule offered scientists a more supple vision of progress. Before its arrival, intellectual life was conducted in grand gestures.
  • Descartes’s book was meant to be a complete overhaul of what had preceded it; its fate, had science not arisen, would have been replacement by some equally expansive system. The iron rule broke that pattern.
  • by authorizing what Strevens calls “shallow explanation,” the iron rule offered an empirical bridge across a conceptual chasm. Work could continue, and understanding could be acquired on the other side. In this way, shallowness was actually more powerful than depth.
  • it also changed what counted as progress. In the past, a theory about the world was deemed valid when it was complete—when God, light, muscles, plants, and the planets cohered. The iron rule allowed scientists to step away from the quest for completeness.
  • The consequences of this shift would become apparent only with time
  • In 1713, Isaac Newton appended a postscript to the second edition of his “Principia,” the treatise in which he first laid out the three laws of motion and the theory of universal gravitation. “I have not as yet been able to deduce from phenomena the reason for these properties of gravity, and I do not feign hypotheses,” he wrote. “It is enough that gravity really exists and acts according to the laws that we have set forth.”
  • What mattered, to Newton and his contemporaries, was his theory’s empirical, predictive power—that it was “sufficient to explain all the motions of the heavenly bodies and of our sea.”
  • Descartes would have found this attitude ridiculous. He had been playing a deep game—trying to explain, at a fundamental level, how the universe fit together. Newton, by those lights, had failed to explain anything: he himself admitted that he had no sense of how gravity did its work
  • Strevens sees its earliest expression in Francis Bacon’s “The New Organon,” a foundational text of the Scientific Revolution, published in 1620. Bacon argued that thinkers must set aside their “idols,” relying, instead, only on evidence they could verify. This dictum gave scientists a new way of responding to one another’s work: gathering data.
  • Quantum theory—which tells us that subatomic particles can be “entangled” across vast distances, and in multiple places at the same time—makes intuitive sense to pretty much nobody.
  • Without the iron rule, Strevens writes, physicists confronted with such a theory would have found themselves at an impasse. They would have argued endlessly about quantum metaphysics.
  • ollowing the iron rule, they can make progress empirically even though they are uncertain conceptually. Individual researchers still passionately disagree about what quantum theory means. But that hasn’t stopped them from using it for practical purposes—computer chips, MRI machines, G.P.S. networks, and other technologies rely on quantum physics.
  • One group of theorists, the rationalists, has argued that science is a new way of thinking, and that the scientist is a new kind of thinker—dispassionate to an uncommon degree.
  • As evidence against this view, another group, the subjectivists, points out that scientists are as hopelessly biased as the rest of us. To this group, the aloofness of science is a smoke screen behind which the inevitable emotions and ideologies hide.
  • At least in science, Strevens tells us, “the appearance of objectivity” has turned out to be “as important as the real thing.”
  • The subjectivists are right, he admits, inasmuch as scientists are regular people with a “need to win” and a “determination to come out on top.”
  • But they are wrong to think that subjectivity compromises the scientific enterprise. On the contrary, once subjectivity is channelled by the iron rule, it becomes a vital component of the knowledge machine. It’s this redirected subjectivity—to come out on top, you must follow the iron rule!—that solves science’s “problem of motivation,” giving scientists no choice but “to pursue a single experiment relentlessly, to the last measurable digit, when that digit might be quite meaningless.”
  • If it really was a speech code that instigated “the extraordinary attention to process and detail that makes science the supreme discriminator and destroyer of false ideas,” then the peculiar rigidity of scientific writing—Strevens describes it as “sterilized”—isn’t a symptom of the scientific mind-set but its cause.
  • The iron rule—“a kind of speech code”—simply created a new way of communicating, and it’s this new way of communicating that created science.
  • Other theorists have explained science by charting a sweeping revolution in the human mind; inevitably, they’ve become mired in a long-running debate about how objective scientists really are
  • In “The Knowledge Machine: How Irrationality Created Modern Science” (Liveright), Michael Strevens, a philosopher at New York University, aims to identify that special something. Strevens is a philosopher of science
  • Compared with the theories proposed by Popper and Kuhn, Strevens’s rule can feel obvious and underpowered. That’s because it isn’t intellectual but procedural. “The iron rule is focused not on what scientists think,” he writes, “but on what arguments they can make in their official communications.”
  • Like everybody else, scientists view questions through the lenses of taste, personality, affiliation, and experience
  • geologists had a professional obligation to take sides. Europeans, Strevens reports, tended to back Wegener, who was German, while scholars in the United States often preferred Simpson, who was American. Outsiders to the field were often more receptive to the concept of continental drift than established scientists, who considered its incompleteness a fatal flaw.
  • Strevens’s point isn’t that these scientists were doing anything wrong. If they had biases and perspectives, he writes, “that’s how human thinking works.”
  • Eddington’s observations were expected to either confirm or falsify Einstein’s theory of general relativity, which predicted that the sun’s gravity would bend the path of light, subtly shifting the stellar pattern. For reasons having to do with weather and equipment, the evidence collected by Eddington—and by his colleague Frank Dyson, who had taken similar photographs in Sobral, Brazil—was inconclusive; some of their images were blurry, and so failed to resolve the matter definitively.
  • it was only natural for intelligent people who were free of the rule’s strictures to attempt a kind of holistic, systematic inquiry that was, in many ways, more demanding. It never occurred to them to ask if they might illuminate more collectively by thinking about less individually.
  • In the single-sphered, pre-scientific world, thinkers tended to inquire into everything at once. Often, they arrived at conclusions about nature that were fascinating, visionary, and wrong.

The Age of Social Media Is Ending - The Atlantic - 0 views

  • Slowly and without fanfare, around the end of the aughts, social media took its place. The change was almost invisible, but it had enormous consequences. Instead of facilitating the modest use of existing connections—largely for offline life (to organize a birthday party, say)—social software turned those connections into a latent broadcast channel. All at once, billions of people saw themselves as celebrities, pundits, and tastemakers.
  • A global broadcast network where anyone can say anything to anyone else as often as possible, and where such people have come to think they deserve such a capacity, or even that withholding it amounts to censorship or suppression—that’s just a terrible idea from the outset. And it’s a terrible idea that is entirely and completely bound up with the concept of social media itself: systems erected and used exclusively to deliver an endless stream of content.
  • “social media,” a name so familiar that it has ceased to bear meaning. But two decades ago, that term didn’t exist
  • ...35 more annotations...
  • a “web 2.0” revolution in “user-generated content,” offering easy-to-use, easily adopted tools on websites and then mobile apps. They were built for creating and sharing “content,”
  • As the original name suggested, social networking involved connecting, not publishing. By connecting your personal network of trusted contacts (or “strong ties,” as sociologists call them) to others’ such networks (via “weak ties”), you could surface a larger network of trusted contacts
  • The whole idea of social networks was networking: building or deepening relationships, mostly with people you knew. How and why that deepening happened was largely left to the users to decide.
  • That changed when social networking became social media around 2009, between the introduction of the smartphone and the launch of Instagram. Instead of connection—forging latent ties to people and organizations we would mostly ignore—social media offered platforms through which people could publish content as widely as possible, well beyond their networks of immediate contacts.
  • Social media turned you, me, and everyone into broadcasters (if aspirational ones). The results have been disastrous but also highly pleasurable, not to mention massively profitable—a catastrophic combination.
  • A social network is an idle, inactive system—a Rolodex of contacts, a notebook of sales targets, a yearbook of possible soul mates. But social media is active—hyperactive, really—spewing material across those networks instead of leaving them alone until needed.
  • The authors propose social media as a system in which users participate in “information exchange.” The network, which had previously been used to establish and maintain relationships, becomes reinterpreted as a channel through which to broadcast.
  • The toxicity of social media makes it easy to forget how truly magical this innovation felt when it was new. From 2004 to 2009, you could join Facebook and everyone you’d ever known—including people you’d definitely lost track of—was right there, ready to connect or reconnect. The posts and photos I saw characterized my friends’ changing lives, not the conspiracy theories that their unhinged friends had shared with them
  • Twitter, which launched in 2006, was probably the first true social-media site, even if nobody called it that at the time. Instead of focusing on connecting people, the site amounted to a giant, asynchronous chat room for the world. Twitter was for talking to everyone—which is perhaps one of the reasons journalists have flocked to it
  • on Twitter, anything anybody posted could be seen instantly by anyone else. And furthermore, unlike posts on blogs or images on Flickr or videos on YouTube, tweets were short and low-effort, making it easy to post many of them a week or even a day.
  • soon enough, all social networks became social media first and foremost. When groups, pages, and the News Feed launched, Facebook began encouraging users to share content published by others in order to increase engagement on the service, rather than to provide updates to friends. LinkedIn launched a program to publish content across the platform, too. Twitter, already principally a publishing platform, added a dedicated “retweet” feature, making it far easier to spread content virally across user networks.
  • When we look back at this moment, social media had already arrived in spirit if not by name. RSS readers offered a feed of blog posts to catch up on, complete with unread counts. MySpace fused music and chatter; YouTube did it with video (“Broadcast Yourself”)
  • From being asked to review every product you buy to believing that every tweet or Instagram image warrants likes or comments or follows, social media produced a positively unhinged, sociopathic rendition of human sociality.
  • Other services arrived or evolved in this vein, among them Reddit, Snapchat, and WhatsApp, all far more popular than Twitter. Social networks, once latent routes for possible contact, became superhighways of constant content
  • Although you can connect the app to your contacts and follow specific users, on TikTok, you are more likely to simply plug into a continuous flow of video content that has oozed to the surface via algorithm.
  • In the social-networking era, the connections were essential, driving both content creation and consumption. But the social-media era seeks the thinnest, most soluble connections possible, just enough to allow the content to flow.
  • This is also why journalists became so dependent on Twitter: It’s a constant stream of sources, events, and reactions—a reporting automat, not to mention an outbound vector for media tastemakers to make tastes.
  • “influencer” became an aspirational role, especially for young people for whom Instagram fame seemed more achievable than traditional celebrity—or perhaps employment of any kind.
  • social-media operators discovered that the more emotionally charged the content, the better it spread across its users’ networks. Polarizing, offensive, or just plain fraudulent information was optimized for distribution. By the time the platforms realized and the public revolted, it was too late to turn off these feedback loops.
  • The ensuing disaster was multipar
  • Rounding up friends or business contacts into a pen in your online profile for possible future use was never a healthy way to understand social relationships.
  • when social networking evolved into social media, user expectations escalated. Driven by venture capitalists’ expectations and then Wall Street’s demands, the tech companies—Google and Facebook and all the rest—became addicted to massive scale
  • Social media showed that everyone has the potential to reach a massive audience at low cost and high gain—and that potential gave many people the impression that they deserve such an audience.
  • On social media, everyone believes that anyone to whom they have access owes them an audience: a writer who posted a take, a celebrity who announced a project, a pretty girl just trying to live her life, that anon who said something afflictive
  • When network connections become activated for any reason or no reason, then every connection seems worthy of traversing.
  • people just aren’t meant to talk to one another this much. They shouldn’t have that much to say, they shouldn’t expect to receive such a large audience for that expression, and they shouldn’t suppose a right to comment or rejoinder for every thought or notion either.
  • Facebook and all the rest enjoyed a massive rise in engagement and the associated data-driven advertising profits that the attention-driven content economy created. The same phenomenon also created the influencer economy, in which individual social-media users became valuable as channels for distributing marketing messages or product sponsorships by means of their posts’ real or imagined reach
  • That’s no surprise, I guess, given that the model was forged in the fires of Big Tech companies such as Facebook, where sociopathy is a design philosophy.
  • If change is possible, carrying it out will be difficult, because we have adapted our lives to conform to social media’s pleasures and torments. It’s seemingly as hard to give up on social media as it was to give up smoking en masse
  • Quitting that habit took decades of regulatory intervention, public-relations campaigning, social shaming, and aesthetic shifts. At a cultural level, we didn’t stop smoking just because the habit was unpleasant or uncool or even because it might kill us. We did so slowly and over time, by forcing social life to suffocate the practice. That process must now begin in earnest for social media.
  • Something may yet survive the fire that would burn it down: social networks, the services’ overlooked, molten core. It was never a terrible idea, at least, to use computers to connect to one another on occasion, for justified reasons, and in moderation
  • The problem came from doing so all the time, as a lifestyle, an aspiration, an obsession. The offer was always too good to be true, but it’s taken us two decades to realize the Faustian nature of the bargain.
  • when I first wrote about downscale, the ambition seemed necessary but impossible. It still feels unlikely—but perhaps newly plausible.
  • To win the soul of social life, we must learn to muzzle it again, across the globe, among billions of people. To speak less, to fewer people and less often–and for them to do the same to you, and everyone else as well
  • We cannot make social media good, because it is fundamentally bad, deep in its very structure. All we can do is hope that it withers away, and play our small part in helping abandon it.

Sarah Palin dives in poll ratings as Tina Fey impersonates her on Saturday Night Live -... - 0 views

  • Palin's poll ratings are telling a more devastating story.
  • In a Newsweek poll in September, voters were asked whether Palin was qualified or unqualified to be president. The result was a near dead-heat. In the same poll this month, those saying she was "unqualified" outnumbered those saying she was "qualified" by a massive 16 points

  • I think that shows that people are looking for different stripes of political news."
  • American political TV certainly is polarised. When Governor Palin attacked the media in her speech at the Republican convention last month, the crowd chanted "NBC"

  • All three major US networks – ABC, CBS and NBC – offer a large amount of serious (and unbiased) political coverage, both in their evening network newscasts and in their morning equivalents of GMTV
  • Impartiality and the public service ethos hardly characterise Tina Fey's performances. Tonight's presidential debate forms part of a series driven largely by commercial networks, not publicly funded channels. Neither Fox News nor MSNBC was set up as a sop to a regulator

PBS Is Creating a Channel Exclusively for Children - The New York Times - 0 views

  • “There’s a huge distinction between the content that’s available through other media providers and PBS,” said Lesli Rotenberg, the broadcaster’s general manager of children’s programming. “Even though there may be more, there isn’t necessarily more educational content for kids.”
  • “There are a lot of children, particularly that are home in early prime time, we aren’t able to accommodate them except for on-demand.
  • “Actually, deep into prime time, there are still a lot of kids watching television

How YouTube Drives People to the Internet's Darkest Corners - WSJ - 0 views

  • YouTube is the new television, with more than 1.5 billion users, and videos the site recommends have the power to influence viewpoints around the world.
  • Those recommendations often present divisive, misleading or false content despite changes the site has recently made to highlight more-neutral fare, a Wall Street Journal investigation found.
  • Behind that growth is an algorithm that creates personalized playlists. YouTube says these recommendations drive more than 70% of its viewing time, making the algorithm among the single biggest deciders of what people watch.
  • ...25 more annotations...
  • People cumulatively watch more than a billion YouTube hours daily world-wide, a 10-fold increase from 2012
  • After the Journal this week provided examples of how the site still promotes deceptive and divisive videos, YouTube executives said the recommendations were a problem.
  • When users show a political bias in what they choose to view, YouTube typically recommends videos that echo those biases, often with more-extreme viewpoints.
  • Such recommendations play into concerns about how social-media sites can amplify extremist voices, sow misinformation and isolate users in “filter bubbles”
  • Unlike Facebook Inc. and Twitter Inc. sites, where users see content from accounts they choose to follow, YouTube takes an active role in pushing information to users they likely wouldn’t have otherwise seen.
  • “The editorial policy of these new platforms is to essentially not have one,”
  • “That sounded great when it was all about free speech and ‘in the marketplace of ideas, only the best ones win.’ But we’re seeing again and again that that’s not what happens. What’s happening instead is the systems are being gamed and people are being gamed.”
  • YouTube has been tweaking its algorithm since last autumn to surface what its executives call “more authoritative” news source
  • YouTube last week said it is considering a design change to promote relevant information from credible news sources alongside videos that push conspiracy theories.
  • The Journal investigation found YouTube’s recommendations often lead users to channels that feature conspiracy theories, partisan viewpoints and misleading videos, even when those users haven’t shown interest in such content.
  • YouTube engineered its algorithm several years ago to make the site “sticky”—to recommend videos that keep users staying to watch still more, said current and former YouTube engineers who helped build it. The site earns money selling ads that run before and during videos.
  • YouTube’s algorithm tweaks don’t appear to have changed how YouTube recommends videos on its home page. On the home page, the algorithm provides a personalized feed for each logged-in user largely based on what the user has watched.
  • There is another way to calculate recommendations, demonstrated by YouTube’s parent, Alphabet Inc.’s Google. It has designed its search-engine algorithms to recommend sources that are authoritative, not just popular.
  • Google spokeswoman Crystal Dahlen said that Google improved its algorithm last year “to surface more authoritative content, to help prevent the spread of blatantly misleading, low-quality, offensive or downright false information,” adding that it is “working with the YouTube team to help share learnings.”
  • In recent weeks, it has expanded that change to other news-related queries. Since then, the Journal’s tests show, news searches in YouTube return fewer videos from highly partisan channels.
  • YouTube’s recommendations became even more effective at keeping people on the site in 2016, when the company began employing an artificial-intelligence technique called a deep neural network that makes connections between videos that humans wouldn’t. The algorithm uses hundreds of signals, YouTube says, but the most important remains what a given user has watched.
  • Using a deep neural network makes the recommendations more of a black box to engineers than previous techniques,
  • “We don’t have to think as much,” he said. “We’ll just give it some raw data and let it figure it out.”
  • To better understand the algorithm, the Journal enlisted former YouTube engineer Guillaume Chaslot, who worked on its recommendation engine, to analyze thousands of YouTube’s recommendations on the most popular news-related queries
  • Mr. Chaslot created a computer program that simulates the “rabbit hole” users often descend into when surfing the site. In the Journal study, the program collected the top five results to a given search. Next, it gathered the top three recommendations that YouTube promoted once the program clicked on each of those results. Then it gathered the top three recommendations for each of those promoted videos, continuing four clicks from the original search.
  • The first analysis, of November’s top search terms, showed YouTube frequently led users to divisive and misleading videos. On the 21 news-related searches left after eliminating queries about entertainment, sports and gaming—such as “Trump,” “North Korea” and “bitcoin”—YouTube most frequently recommended these videos:
  • The algorithm doesn’t seek out extreme videos, they said, but looks for clips that data show are already drawing high traffic and keeping people on the site. Those videos often tend to be sensationalist and on the extreme fringe, the engineers said.
  • Repeated tests by the Journal as recently as this week showed the home page often fed far-right or far-left videos to users who watched relatively mainstream news sources, such as Fox News and MSNBC.
  • Searching some topics and then returning to the home page without doing a new search can produce recommendations that push users toward conspiracy theories even if they seek out just mainstream sources.
  • After searching for “9/11” last month, then clicking on a single CNN clip about the attacks, and then returning to the home page, the fifth and sixth recommended videos were about claims the U.S. government carried out the attacks. One, titled “Footage Shows Military Plane hitting WTC Tower on 9/11—13 Witnesses React”—had 5.3 million views.

Erick Erickson: How to Find Common Ground - The New York Times - 1 views

  • Our family life is now focused on three-month windows of normalcy between my wife’s CT scans.
  • Contemplating these things, last November I posted a short essay on my website of things I would want my children to know if their mother and I died before they woke.
  • I want them to do what is right, not what is popular, and I want them to measure their self-worth by being ethical individuals, not by the applause they receive on social media.
  • ...7 more annotations...
  • As we have moved more of our lives onto the internet, we have stopped living in actual communities. Instead we have created virtual communities where everyone thinks the same. We do not have to worry about the homeless man under the bridge because he is no longer part of our community. He is someone else’s problem. But that simply is not true.
  • Not everything should be political, and we can only make everything political when we decide the other side is evil just because they disagree with us. We can see the world only in this polarized way if we never take the time to know anyone on the other side, if we never find ways to build friendship despite our differences.
  • Even as the internet provides us great advances, it also segments us. We have social-media tribes and our self-esteem is based on likes and retweets. We have hundreds of television channels and even more video choices online where Hollywood no longer has to worry about broad appeal. There is a channel for everyone, and everyone in the tribe will get the inside jokes. Social-media interactions have replaced the value of character.
  • The kitchen table is the most important tool they have to reshape their community. Preparing a home-cooked meal and inviting people over, both those we know and those we want to know, forces us to find common ground.
  • The truth, though, is that our Facebook friends are probably not going to water our flowers while we are on vacation and our Twitter followers will not bring us a meal if we are sick. But the actual human being next door might do both if we meet him.
  • Every person has an interesting story to tell. I want my children to know my story.
  • We may also never find that common ground with people whose politics or faith conflicts with ours. But we owe it to one another to disagree agreeably, without anger or intimidation, whether on a front porch or a Facebook page. A little more grace among us all would go a long way toward healing the nation.

COVID-19 and Compassion Fatigue | Psychology Today - 0 views

  • “Researchers say our brains aren’t wired to make sense of big numbers.” A story about a single tragic death evokes waves of sadness and emotion in us. We focus on the individual’s details, their life story, and the circumstances of their death. As the number of victims increases, our ability to muster empathy fades, something often called compassion fatigue.
  • If we talk instead about multiple people like Constance Johnson at once or just give the numbers involved—about 4,200 women die every year from cervical cancer—the information loses its impact. We don’t comprehend a number like 4,200 the way we do the story of a single individual.
  • As the&nbsp;results of a study by Paul Slovic and colleagues in 2014 showed, the&nbsp;tendency to be charitable and feel compassion diminishes rapidly as the number of people involved increases from one.
  • ...5 more annotations...
  • In support of compassion fatigue, both self-report and physiological measures of affect showed that positive affect declined substantially when the group size was two or more.”
  • After several puffs of neurotransmitter are released, however, that channel may undergo a process called “desensitization” in which it closes and stops responding to signals from the presynaptic neuron.
  • “Observing that the tendency to mentalize with one person more than many people is built into our brains does not mean we should accept it as an excuse for acting passively when facing large-scale crises. This observation implies, however, that we can no longer rely on our moral intuitions.”
  • eople may cope with the enormity of the pandemic by trying to find ways to minimize or even dismiss it. Saying that there are other diseases that cause more deaths than COVID-19 could be one such emotional mechanism.
  • We need to tell more stories about real people who have had COVID-19 and experienced it as more than mild symptoms, including stories about people who have been killed by&nbsp;the disease. The stories need to be told one by one. That way, we will be harnessing what we know from cognitive neuroscience to bring the sad message home.

Fox News's Election Coverage Followed Journalistic Instincts - NYTimes.com - 0 views

  • It has been suggested, here and elsewhere, that Fox News effectively became part of the Republican propaganda apparatus during the presidential campaign by giving pundit slots to many of the Republican candidates and relentlessly advocating for Mitt Romney once he won the nomination. Over many months, Fox lulled its conservative base with agitprop: that President Obama was a clear failure, that a majority of Americans saw Mr. Romney as a good alternative in hard times, and that polls showing otherwise were politically motivated and not to be believed. But on Tuesday night, the people in charge of Fox News were confronted with a stark choice after it became clear that Mr. Romney had fallen short: was Fox, first and foremost, a place for advocacy or a place for news?

One of Us - Lapham's Quarterly - 0 views

  • On what seems like a monthly basis, scientific teams announce the results of new experiments, adding to a preponderance of evidence that we’ve been underestimating animal minds, even those of us who have rated them fairly highly
  • an international group of prominent neuroscientists meeting at the University of Cambridge issued “The Cambridge Declaration on Consciousness in Non-Human Animals,” a document stating that “humans are not unique in possessing the neurological substrates that generate consciousness.” It goes further to conclude that numerous documented animal behaviors must be considered “consistent with experienced feeling states.”
  • Only with the Greeks does there enter the notion of a formal divide between our species, our animal, and every other on earth.

  • there’s that exquisite verse, one of the most beautiful in the Bible, the one that says if God cares deeply about sparrows, don’t you think He cares about you? One is so accustomed to dwelling on the second, human, half of the equation, the comforting part, but when you put your hand over that and consider only the first, it’s a little startling: God cares deeply about the sparrows. Not just that, He cares about them individually. “Are not five sparrows sold for two pennies?” Jesus says. “Yet not one of them is forgotten in God’s sight.”
  • The modern conversation on animal consciousness proceeds, with the rest of the Enlightenment, from the mind of René Descartes, whose take on animals was vividly (and approvingly) paraphrased by the French philosopher Nicolas Malebranche: they “eat without pleasure, cry without pain, grow without knowing it; they desire nothing, fear nothing, know nothing.” Descartes’ term for them was automata
  • In On the Origin of Species, Charles Darwin made the intriguing claim that among the naturalists he knew it was consistently the case that the better a researcher got to know a certain species, the more each individual animal’s actions appeared attributable to “reason and the less to unlearnt instinct.” The more you knew, the more you suspected that they were rational. That marks an important pivot, that thought, insofar as it took place in the mind of someone devoted to extremely close and meticulous study of living animals, a mind that had trained itself not to sentimentalize.
  • The sheer number and variety of experiments carried out in the twentieth century—and with, if anything, a renewed intensity in the twenty-first—exceeds summary. Reasoning, language, neurology, the science of emotions—every chamber where “consciousness” is thought to hide has been probed. Birds and chimps and dolphins have been made to look at themselves in mirrors—to observe whether, on the basis of what they see, they groom or preen (a measure, if somewhat arbitrary, of self-awareness). Dolphins have been found to grieve. Primates have learned symbolic or sign languages and then been interrogated with them. Their answers show thinking but have proved stubbornly open to interpretation on the issue of “consciousness,” with critics warning, as always, about the dangers of anthropomorphism, animal-rights bias, etc.
  • If we put aside the self-awareness standard—and really, how arbitrary and arrogant is that, to take the attribute of consciousness we happen to possess over all creatures and set it atop the hierarchy, proclaiming it the very definition of consciousness (Georg Christoph Lichtenberg wrote something wise in his notebooks, to the effect of: only a man can draw a self-portrait, but only a man wants to)—it becomes possible to say at least the following: the overwhelming tendency of all this scientific work, of its results, has been toward more consciousness. More species having it, and species having more of it than assumed.
  • The animal kingdom is symphonic with mental activity, and of its millions of wavelengths, we’re born able to understand the minutest sliver. The least we can do is have a proper respect for our ignorance.
  • The philosopher Thomas Nagel wrote an essay in 1974 titled, “What Is It Like To Be a Bat?”, in which he put forward perhaps the least overweening, most useful definition of “animal consciousness” ever written, one that channels Spinoza’s phrase about “that nature belonging to him wherein he has his being.” Animal consciousness occurs, Nagel wrote, when “there is something that it is to be that organism—something it is like for the organism.” The strangeness of his syntax carries the genuine texture of the problem. We’ll probably never be able to step far enough outside of our species-reality to say much about what is going on with them, beyond saying how like or unlike us they are. Many things are conscious on the earth, and we are one, and our consciousness feels like this; one of the things it causes us to do is doubt the existence of the consciousness of the other millions of species. But it also allows us to imagine a time when we might stop doing that.

Inequality and the Modern Culture of Celebrity - NYTimes.com - 0 views

  • The Depression that ended Fitzgerald’s Jazz Age yielded to a new order that might be called the Roosevelt Republic. In the quarter-century after World War II, the country established collective structures, not individual monuments, that channeled the aspirations of ordinary people: state universities, progressive taxation, interstate highways, collective bargaining, health insurance for the elderly, credible news organizations.
  • One virtue of those hated things called bureaucracies is that they oblige everyone to follow a common set of rules, regardless of station or background; they are inherently equalizing.
  • Our age is lousy with celebrities. They can be found in every sector of society, including ones that seem less than glamorous
  • ...2 more annotations...
  • This new kind of celebrity is the ultimate costume ball, far more exclusive and decadent than even the most potent magnates of Hollywood’s studio era could have dreamed up.
  • after decades of widening income gaps, unequal distributions of opportunity and reward, and corroding public institutions, we have gone back to Gatsby’s time — or something far more perverse. The celebrity monuments of our age have grown so huge that they dwarf the aspirations of ordinary people, who are asked to yield their dreams to the gods: to flash their favorite singer’s corporate logo at concerts, to pour open their lives (and data) on Facebook, to adopt Apple as a lifestyle. We know our stars aren’t inviting us to think we can be just like them. Their success is based on leaving the rest of us behind.

Ad About Women's Self-Image Creates a Sensation - NYTimes.com - 0 views

  • An online video, presented in three- and six-minute versions, shows a forensic sketch artist who is asked to draw a series of women based only on their descriptions. Seated at a drafting table with his back to his subject, the artist, Gil Zamora, asks the women a series of questions about their features. “Tell me about your chin,” he says in the soft voice reminiscent of a therapist’s. Crow’s feet, big jaws, protruding chins and dark circles are just some of the many physical features that women criticized about themselves. After he finishes a drawing of a woman, he then draws another sketch of the same woman, only this time it is based on how someone else describes her. The sketches are then hung side by side and the women are asked to compare them. In every instance, the second sketch is more flattering than the first.
  • The video, shot in a loft in San Francisco, has become a sensation online. The three-minute version has been viewed more than 7.5 million times on the Dove YouTube channel, and the version that is twice as long has been viewed more than 936,000 times.
  • Dove executives said the campaign resulted from company research that showed only 4 percent of women consider themselves beautiful.
  • ...3 more annotations...
  • “As women we are so hard on ourselves physically and emotionally,” Ms. Olive said. “It gets you to stop and think about how we think of ourselves.”
  • Ms. Brice took issue with the tag line for the ad, “You’re More Beautiful Than You Think.” “I think it makes people much more susceptible to absorbing the subconscious messages,” Ms. Brice said, “that at the heart of it all is that beauty is still what defines women. It is a little hypocritical.”
  • “What if I did look like that woman on the left?” she said, referring to the less flattering sketches of the women. “There are people that look like that.”
