What Architecture Is Doing to Your Brain - CityLab - 1 views

  • Much of the student population would likely agree that the library’s menacing figure on the quad is nothing short of soul-crushing. New research conducted by a team of architects and neuroscientists suggests that architecture may indeed affect mental states, though they choose to focus on the positive.
  • I spoke with Dr. Julio Bermudez, the lead of a new study that uses fMRI to capture the effects of architecture on the brain. His team operates with the goal of using the scientific method to transform something opaque—the qualitative “phenomenologies of our built environment”—into neuroscientific observations that architects and city planners can deliberately design for. Bermudez and his team’s research question focuses on buildings and sites designed to elicit contemplation: They theorize that the presence of “contemplative architecture” in one’s environment may over time produce the same health benefits as traditional “internally induced” meditation, except with much less effort by the individual.
  • By showing 12 architects photos of contemplative and non-contemplative buildings from facade to interior, the researchers were able to observe the brain activity that occurred as subjects "imagined they were transported to the places being shown." All of the architects were white, right-handed men with no prior meditative training, creating the necessary (if comical) uniformity for neuroscientific research—the team wanted to ensure that the brain scans would not be influenced by factors unrelated to the photos, like gender, race, or handedness. For instance, the brain scans of left- and right-handed people often look different even when subjects are performing the same task.

  • In addition to posing an interesting control on the experiment, the decision to use architects was a strategic one meant to increase the researchers’ chances of achieving conclusive results. Though everyone encounters architecture, studies on the built environment struggle for funding because, as Bermudez remarked with a sigh, “it’s difficult to suggest that people are dying from it.” Architects were a natural choice for the pilot study because, the team reasoned, their critical training and experience would make them sensitive to features of the buildings that a lay person might overlook.
  • they deployed online surveys in Spanish and English to gather testimony on extraordinary architectural experiences (EAEs), or encounters with places that fundamentally alter one’s normal state of being. Critically, most of the buildings or sites mentioned in the 2,982 testimonies were designed with contemplation in mind, whether spiritual, aesthetic, religious, or symbolic, leading the researchers to conclude that “buildings may induce insightful, profound, and transformative contemplative states, [and] buildings designed to provoke contemplation seem to be succeeding”
  • Anticipating skeptics who would claim that these experiences are subjective, the researchers expanded the question to draw on the established neuroscientific subfield of meditation, with some important differences. Related studies to date have focused on internally produced states that are easily replicated in the lab, and on aesthetic evaluation, or the activity that occurs in the orbital frontal cortex as we make snap judgments about whether we find things ugly or beautiful.
  • Bermudez and his team expected that architecturally induced contemplative states would be strong, non-evaluative aesthetic experiences— eliciting more activity in areas associated with emotion and pleasure, but less activity in the orbital frontal cortex.
  • The presence of an external stimulus (the photos of the buildings) also removes the tedious self-regulation that occurs in the prefrontal cortex during traditional meditation. The interviews of the 12 subjects revealed that “peacefulness and relaxation, lessening of mind wandering, increasing of attention, and deepening of experience” were all common effects of viewing the photos—also common was a slight element of aesthetic judgment, seemingly inescapable in the crowd of critics.
  • The provisional conclusions of the study are that the brain behaves differently when exposed to contemplative and non-contemplative buildings, contemplative states elicited through “architectural aesthetics” are similar to the contemplation of traditional meditation in some ways, and different in other ways, and, finally, that “architectural design matters.”
  • reinforces a growing trend in architecture and design as researchers are beginning to study how the built environment affects the people who live in it. ANFA proclaims that “some observers have characterized what is happening in neuroscience as the most exciting frontier of human discovery since the Renaissance.”
  • gritty details: the optimal ceiling heights for different cognitive functions; the best city design for eliciting our natural exploratory tendencies and making way-finding easier; the ideal hospital layout to improve memory-related tasks in patients recovering from certain brain injuries; the influence of different types and quantities of light within a built space on mood and performance.

Smart Buildings: Architects Turn to Brain Science | Al Jazeera America - 0 views

  • The public middle school, which is part of a larger complex that includes Corona del Mar High School, now is attracting more students who would normally have gone to private school in this affluent Orange County district, said Principal Rebecca Gogel. “There has been a significant change in student behavior,” she said.
  • But what has gone into the design of this school goes much deeper than sheer aesthetics. Architects are now applying neuroscience to design schools, hospitals, community centers and even single-family homes.

  • The role of neuroscience in architecture is a contemporary concept that attaches scientific proof, measurement and research to the design of buildings.
  • The brain controls behavior, and genes control the design and structure of the brain. Science shows that environment can modulate the function of genes and, ultimately, the structure of the brain. So if changes in the environment change behavior, architectural design can change it too.

A Modest Proposal for More Back-Stabbing in Preschool - NYTimes.com - 0 views

  • I am a deluded throwback to carefree days, and in my attempt to raise a conscious, creative and socially and environmentally responsible child while lacking the means to also finance her conscious, creative and environmentally and socially responsible lifestyle forever, I’d accidentally gone and raised a hothouse serf. Oops.
  • Reich’s thesis is that some inequality is inevitable, even necessary, in a free-market system. But what makes an economy stable and prosperous is a strong, vibrant, growing middle class. In the three decades after World War II, a period that Reich calls “the great prosperity,” the G.I. Bill, the expansion of public universities and the rise of labor unions helped create the biggest, best-educated middle class in the world. Reich describes this as an example of a “virtuous circle” in which productivity grows, wages increase, workers buy more, companies hire more, tax revenues increase, government invests more, workers are better educated. On the flip side, when the middle class doesn’t share in the economic gains, it results over time in a downward vicious cycle: Wages stagnate, workers buy less, companies downsize, tax revenues decrease, government cuts programs, workers are less educated, unemployment rises, deficits grow. Since the crash that followed the deregulation of the financial markets, we have struggled to emerge from such a cycle.

  • Are we feeding our children a bunch of dangerous illusions about fairness and hard work and level playing fields? Are ideals a luxury only the rich can afford?
  • I’m reminded of the quote by John Adams: “I must study politics and war, that my sons may have the liberty to study mathematics and philosophy. My sons ought to study mathematics and philosophy, geography, natural history [and] naval architecture . . . in order to give their children a right to study painting, poetry, music, architecture, tapestry and porcelain.” For all intents and purposes, I guess I studied porcelain. The funny thing is that my parents came from a country (Peru) with a middle class so small that parents had to study business so that their children could study business. If I didn’t follow suit, it’s at least in part because I spent my childhood in the 1970s absorbing the nurturing message of a progressive pop culture that told me I could be anything I wanted, because this is America.

CES 2020: Toyota is building a 'smart' city to test AI, robots and self-driving cars - ... - 0 views

  • armaker Toyota has unveiled plans for a 2,000-person "city of the future," where it will test autonomous vehicles, smart technology and robot-assisted living.
  • "With people buildings and vehicles all connected and communicating with each other through data and sensors, we will be able to test AI technology, in both the virtual and the physical world, maximizing its potential," he said on stage during Tuesday's unveiling. "We want to turn artificial intelligence into intelligence amplified."
  • The project is a collaboration between the Japanese carmaker and Danish architecture firm Bjarke Ingels Group (BIG), which designed the city's master plan. Buildings on the site will be made primarily from wood, and partly constructed using robotics. But the designs also look to Japan's past for inspiration, incorporating traditional joinery techniques and the sweeping roofs characteristic of the country's architecture.

  • Smart technology will extend inside residents' homes, according to Ingels, whose firm also designed the 2 World Trade Center in New York, and Google's headquarters in both London and Silicon Valley.
  • "In an age when technology, social media and online retail is replacing and eliminating our natural meeting places, the Woven City will explore ways to stimulate human interaction in the urban space," he said. "After all, human connectivity is the kind of connectivity that triggers wellbeing and happiness, productivity and innovation."

Understanding What's Wrong With Facebook | Talking Points Memo - 0 views

  • to really understand the problem with Facebook we need to understand the structural roots of that problem, how much of it is baked into the core architecture of the site and its very business model
  • much of it is inherent in the core strategies of the post-2000, second wave Internet tech companies that now dominate our information space and economy.
  • Facebook is an ingenious engine for information and ideational manipulation.
  • ...17 more annotations...
  • Good old fashioned advertising does that to a degree. But Facebook is much more powerful, adaptive and efficient.
  • Facebook is designed to do specific things. It’s an engine to understand people’s minds and then manipulate their thinking.
  • Those tools are refined for revenue making but can be used for many other purposes. That makes it ripe for misuse and bad acting.
  • The core of all second wave Internet commerce operations was finding network models where costs grow mathematically and revenues grow exponentially.
  • The network and its dominance is the product and once it takes hold the cost inputs remained constrained while the revenues grow almost without limit.
  • Facebook is best understood as a fantastically profitable nuclear energy company whose profitability is based on dumping the waste on the side of the road and accepting frequent accidents and explosions as inherent to the enterprise.
  • That’s why these companies employ so few people relative to scale and profitability.
  • That’s why there’s no phone support for Google or Facebook or Twitter. If half the people on the planet are ‘customers’ or users that’s not remotely possible.
  • The core economic model requires doing all of it on the cheap. Indeed, what Zuckerberg et al. have created with Facebook is so vast that the money required not to do it on the cheap almost defies imagination.
  • Facebook’s core model and concept requires not taking responsibility for what others do with the engine created to drive revenue.
  • It all amounts to a grand exercise in socializing the externalities and keeping all the revenues for the owners.
  • Here’s a way to think about it. Nuclear power is actually incredibly cheap. The fuel is fairly plentiful and easy to pull out of the ground. You set up a little engine and it generates energy almost without limit. What makes it ruinously expensive is managing the externalities – all the risks and dangers, the radiation, accidents, the constant production of radioactive waste.
  • managing or distinguishing between legitimate and bad-acting uses of the powerful Facebook engine is one that would require huge, huge investments of money and armies of workers to manage
  • But back to Facebook. The point is that they’ve created a hugely powerful and potentially very dangerous machine
  • The core business model is based on harvesting the profits from the commercial uses of the machine and using algorithms and very, very limited personnel (relative to scale) to try to get a handle on the most outrageous and shocking abuses which the engine makes possible.
  • Zuckerberg may be a jerk and there really is a culture of bad acting within the organization. But it’s not about him being a jerk. Replace him and his team with non-jerks and you’d still have a similar core problem.
  • To manage the potential negative externalities, to take some responsibility for all the dangerous uses the engine makes possible would require money the owners are totally unwilling and in some ways are unable to spend.

The Man Who Would Teach Machines to Think - James Somers - The Atlantic - 1 views

  • Douglas Hofstadter, the Pulitzer Prize–winning author of Gödel, Escher, Bach, thinks we've lost sight of what artificial intelligence really means. His stubborn quest to replicate the human mind.
  • “If somebody meant by artificial intelligence the attempt to understand the mind, or to create something human-like, they might say—maybe they wouldn’t go this far—but they might say this is some of the only good work that’s ever been done
  • Their operating premise is simple: the mind is a very unusual piece of software, and the best way to understand how a piece of software works is to write it yourself.

  • “It depends on what you mean by artificial intelligence.”
  • Computers are flexible enough to model the strange evolved convolutions of our thought, and yet responsive only to precise instructions. So if the endeavor succeeds, it will be a double victory: we will finally come to know the exact mechanics of our selves—and we’ll have made intelligent machines.
  • Ever since he was about 14, when he found out that his youngest sister, Molly, couldn’t understand language, because she “had something deeply wrong with her brain” (her neurological condition probably dated from birth, and was never diagnosed), he had been quietly obsessed by the relation of mind to matter.
  • How could consciousness be physical? How could a few pounds of gray gelatin give rise to our very thoughts and selves?
  • Consciousness, Hofstadter wanted to say, emerged via just the same kind of “level-crossing feedback loop.”
  • In 1931, the Austrian-born logician Kurt Gödel had famously shown how a mathematical system could make statements not just about numbers but about the system itself.
  • But then AI changed, and Hofstadter didn’t change with it, and for that he all but disappeared.
  • By the early 1980s, the pressure was great enough that AI, which had begun as an endeavor to answer yes to Alan Turing’s famous question, “Can machines think?,” started to mature—or mutate, depending on your point of view—into a subfield of software engineering, driven by applications.
  • Take Deep Blue, the IBM supercomputer that bested the chess grandmaster Garry Kasparov. Deep Blue won by brute force.
  • Hofstadter wanted to ask: Why conquer a task if there’s no insight to be had from the victory? “Okay,” he says, “Deep Blue plays very good chess—so what? Does that tell you something about how we play chess? No. Does it tell you about how Kasparov envisions, understands a chessboard?”
  • AI started working when it ditched humans as a model, because it ditched them. That’s the thrust of the analogy: Airplanes don’t flap their wings; why should computers think?
  • It’s a compelling point. But it loses some bite when you consider what we want: a Google that knows, in the way a human would know, what you really mean when you search for something

  • analogy is “the fuel and fire of thinking,” the bread and butter of our daily mental lives.
  • there’s an analogy, a mental leap so stunningly complex that it’s a computational miracle: somehow your brain is able to strip any remark of the irrelevant surface details and extract its gist, its “skeletal essence,” and retrieve, from your own repertoire of ideas and experiences, the story or remark that best relates.
  • in Hofstadter’s telling, the story goes like this: when everybody else in AI started building products, he and his team, as his friend, the philosopher Daniel Dennett, wrote, “patiently, systematically, brilliantly,” way out of the light of day, chipped away at the real problem. “Very few people are interested in how human intelligence works,”

  • project out of IBM called Candide. The idea behind Candide, a machine-translation system, was to start by admitting that the rules-based approach requires too deep an understanding of how language is produced; how semantics, syntax, and morphology work; and how words commingle in sentences and combine into paragraphs—to say nothing of understanding the ideas for which those words are merely conduits.
  • , Hofstadter directs the Fluid Analogies Research Group, affectionately known as FARG.
  • Parts of a program can be selectively isolated to see how it functions without them; parameters can be changed to see how performance improves or degrades. When the computer surprises you—whether by being especially creative or especially dim-witted—you can see exactly why.
  • When you read Fluid Concepts and Creative Analogies: Computer Models of the Fundamental Mechanisms of Thought, which describes in detail this architecture and the logic and mechanics of the programs that use it, you wonder whether maybe Hofstadter got famous for the wrong book.
  • ut very few people, even admirers of GEB, know about the book or the programs it describes. And maybe that’s because FARG’s programs are almost ostentatiously impractical. Because they operate in tiny, seemingly childish “microdomains.” Because there is no task they perform better than a human.
  • “The entire effort of artificial intelligence is essentially a fight against computers’ rigidity.”
  • “Nobody is a very reliable guide concerning activities in their mind that are, by definition, subconscious,” he once wrote. “This is what makes vast collections of errors so important. In an isolated error, the mechanisms involved yield only slight traces of themselves; however, in a large collection, vast numbers of such slight traces exist, collectively adding up to strong evidence for (and against) particular mechanisms.
  • So IBM threw that approach out the window. What the developers did instead was brilliant, but so straightforward,
  • The technique is called “machine learning.” The goal is to make a device that takes an English sentence as input and spits out a French sentence
  • What you do is feed the machine English sentences whose French translations you already know. (Candide, for example, used 2.2 million pairs of sentences, mostly from the bilingual proceedings of Canadian parliamentary debates.)
  • By repeating this process with millions of pairs of sentences, you will gradually calibrate your machine, to the point where you’ll be able to enter a sentence whose translation you don’t know and get a reasonable resul
  • Google Translate team can be made up of people who don’t speak most of the languages their application translates. “It’s a bang-for-your-buck argument,” Estelle says. “You probably want to hire more engineers instead” of native speakers.
  • But the need to serve 1 billion customers has a way of forcing the company to trade understanding for expediency. You don’t have to push Google Translate very far to see the compromises its developers have made for coverage, and speed, and ease of engineering. Although Google Translate captures, in its way, the products of human intelligence, it isn’t intelligent itself.
  • “Did we sit down when we built Watson and try to model human cognition?” Dave Ferrucci, who led the Watson team at IBM, pauses for emphasis. “Absolutely not. We just tried to create a machine that could win at Jeopardy.”
  • For Ferrucci, the definition of intelligence is simple: it’s what a program can do. Deep Blue was intelligent because it could beat Garry Kasparov at chess. Watson was intelligent because it could beat Ken Jennings at Jeopardy.
  • “There’s a limited number of things you can do as an individual, and I think when you dedicate your life to something, you’ve got to ask yourself the question: To what end? And I think at some point I asked myself that question, and what it came out to was, I’m fascinated by how the human mind works, it would be fantastic to understand cognition, I love to read books on it, I love to get a grip on it”—he called Hofstadter’s work inspiring—“but where am I going to go with it? Really what I want to do is build computer systems that do something.
  • Peter Norvig, one of Google’s directors of research, echoes Ferrucci almost exactly. “I thought he was tackling a really hard problem,” he told me about Hofstadter’s work. “And I guess I wanted to do an easier problem.”
  • Of course, the folly of being above the fray is that you’re also not a part of it
  • As our machines get faster and ingest more data, we allow ourselves to be dumber. Instead of wrestling with our hardest problems in earnest, we can just plug in billions of examples of them.
  • Hofstadter hasn’t been to an artificial-intelligence conference in 30 years. “There’s no communication between me and these people,” he says of his AI peers. “None. Zero. I don’t want to talk to colleagues that I find very, very intransigent and hard to convince of anything
  • Everything from plate tectonics to evolution—all those ideas, someone had to fight for them, because people didn’t agree with those ideas.
  • Academia is not an environment where you just sit in your bath and have ideas and expect everyone to run around getting excited. It’s possible that in 50 years’ time we’ll say, ‘We really should have listened more to Doug Hofstadter.’ But it’s incumbent on every scientist to at least think about what is needed to get people to understand the ideas.”

Facebook's Subtle Empire - The New York Times - 1 views

  • Mark Zuckerberg’s empire has become an immensely powerful media organization in its own right, albeit one that effectively subcontracts actual news gathering to other entities (this newspaper included).

New Ways Into the Brain's 'Music Room' - The New York Times - 5 views

  • Every culture ever studied has been found to make music, and among the oldest artistic objects known are slender flutes carved from mammoth bone some 43,000 years ago — 24,000 years before the cave paintings of Lascaux.
  • , many researchers had long assumed that the human brain must be equipped with some sort of music room, a distinctive piece of cortical architecture dedicated to detecting and interpreting the dulcet signals of song. Yet for years, scientists failed to find any clear evidence of a music-specific domain through conventional brain-scanning technology
  • devised a radical new approach to brain imaging that reveals what past studies had missed. By mathematically analyzing scans of the auditory cortex and grouping clusters of brain cells with similar activation patterns, the scientists have identified neural pathways that react almost exclusively to the sound of music — any music. It may be Bach, bluegrass, hip-hop, big band, sitar or Julie Andrews. A listener may relish the sampled genre or revile it. No matter. When a musical passage is played, a distinct set of neurons tucked inside a furrow of a listener’s auditory cortex will fire in response.Other sounds, by contrast — a dog barking, a car skidding, a toilet flushing — leave the musical circuits unmoved.
  • ...11 more annotations...
  • “Why do we have music?” Dr. Kanwisher said in an interview. “Why do we enjoy it so much and want to dance when we hear it? How early in development can we see this sensitivity to music, and is it tunable with experience? These are the really cool first-order questions we can begin to address.”
  • Dr. McDermott said the new method could be used to computationally dissect any scans from a functional magnetic resonance imaging device, or F.M.R.I. — the trendy workhorse of contemporary neuroscience — and so may end up divulging other hidden gems of cortical specialization. As proof of principle, the researchers showed that their analytical protocol had detected a second neural pathway in the brain for which scientists already had evidence — this one tuned to the sounds of human speech.
  • Importantly, the M.I.T. team demonstrated that the speech and music circuits are in different parts of the brain’s sprawling auditory cortex, where all sound signals are interpreted, and that each is largely deaf to the other’s sonic cues, although there is some overlap when it comes to responding to songs with lyrics.
  • In fact, Dr. Rauschecker said, music sensitivity may be more fundamental to the human brain than is speech perception. “There are theories that music is older than speech or language,” he said. “Some even argue that speech evolved from music.”
  • And though the survival value that music held for our ancestors may not be as immediately obvious as the power to recognize words, Dr. Rauschecker added, “music works as a group cohesive. Music-making with other people in your tribe is a very ancient, human thing to do.”
  • when previous neuroscientists failed to find any anatomically distinct music center in the brain, they came up with any number of rationales to explain the results.“The story was, oh, what’s special about music perception is how it recruits areas from all over the brain, how it draws on the motor system, speech circuitry, social understanding, and brings it all together,” she said. Some researchers dismissed music as “auditory cheesecake,” a pastime that co-opted other essential communicative urges. “This paper says, no, when you peer below the cruder level seen with some methodologies, you find very specific circuitry that responds to music over speech.”
  • The researchers wondered if the auditory system might be similarly organized to make sense of the soundscape through a categorical screen. If so, what would the salient categories be? What are the aural equivalents of a human face or a human leg — sounds or sound elements so essential the brain assigns a bit of gray matter to the task of detecting them?
  • Focusing on the brain’s auditory region — located, appropriately enough, in the temporal lobes right above the ears — the scientists analyzed voxels, or three-dimensional pixels, of the images mathematically to detect similar patterns of neuronal excitement or quietude.“The strength of our method is that it’s hypothesis-neutral,” Dr. McDermott said. “We just present a bunch of sounds and let the data do the talking.”
  • Matching sound clips to activation patterns, the researchers determined that four of the patterns were linked to general physical properties of sound, like pitch and frequency. The fifth traced the brain’s perception of speech, and for the sixth the data turned operatic, disclosing a neuronal hot spot in the major crevice, or sulcus, of the auditory cortex that attended to every music clip the researchers had played.
  • “The sound of a solo drummer, whistling, pop songs, rap, almost everything that has a musical quality to it, melodic or rhythmic, would activate it,” Dr. Norman-Haignere said. “That’s one reason the result surprised us. The signals of speech are so much more homogeneous.”
  • The researchers have yet to determine exactly which acoustic features of music stimulate its dedicated pathway. The relative constancy of a musical note’s pitch? Its harmonic overlays? Even saying what music is can be tricky.

How 'Empowerment' Became Something for Women to Buy - The New York Times - 0 views

  • The mix of things presumed to transmit and increase female power is without limit yet still depressingly limiting.“Empowerment” wasn’t always so trivialized, or so corporate, or even so clamorously attached to women.
  • Four decades ago, the word had much more in common with Latin American liberation theology than it did with “Lean In.” In 1968, the Brazilian academic Paulo Freire coined the word “conscientization,” empowerment’s precursor, as the process by which an oppressed person perceives the structural conditions of his oppression and is subsequently able to take action against his oppressors.
  • Eight years later, the educator Barbara Bryant Solomon, writing about American black communities, gave this notion a new name, “empowerment.” It was meant as an ethos for social workers in marginalized communities, to discourage paternalism and encourage their clients to solve problems in their own ways. Then in 1981, Julian Rappaport, a psychologist, broadened the concept into a political theory of power that viewed personal competency as fundamentally limitless; it placed faith in the individual and laid at her feet a corresponding amount of responsibility too.

  • Sneakily, empowerment had turned into a theory that applied to the needy while describing a process more realistically applicable to the rich. The word was built on a misaligned foundation; no amount of awareness can change the fact that it’s the already-powerful who tend to experience empowerment at any meaningful rate. Today “empowerment” invokes power while signifying the lack of it. It functions like an explorer staking a claim on new territory with a white flag.
  • highly marketable “women’s empowerment,” neither practice nor praxis, nor really theory, but a glossy, dizzying product instead. Women’s empowerment borrows the virtuous window-dressing of the social worker’s doctrine and kicks its substance to the side. It’s about pleasure, not power; it’s individualistic and subjective, tailored to insecurity and desire.
  • The new empowerment doesn’t increase potential so much as it assures you that your potential is just fine. Even when the thing being described as “empowering” is personal and mildly defiant (not shaving, not breast-feeding, not listening to men, et cetera), what’s being mar­keted is a certain identity.
  • When consumer purchases aren’t made out to be a path to female empowerment, a branded corporate experience often is. There’s TEDWomen (“about the power of women”), the Forbes Women’s Summit (“#RedefinePower”) and Fortune’s Most Powerful Women Conference (tickets are $10,000).
  • This consumption-and-conference empowerment dilutes the word to pitch-speak, and the concept to something that imitates rather than alters the structures of the world. This version of empowerment can be actively disempowering: It’s a series of objects and experiences you can purchase while the conditions determining who can access and accumulate power stay the same. The ready partici­pation of well-off women in this strat­egy also points to a deep truth about the word “empowerment”: that it has never been defined by the people who actually need it. People who talk empowerment are, by definition, already there.
  • I have never said “empowerment” sincerely or heard it from a single one of my friends. The formulation has been diluted to something representational and bloodless — an architectural rendering of a building that will never be built.But despite its nonexistence in honest conversation, “empowerment” goes on thriving. It’s uniquely marketable, like the female body, which is where women’s empowerment is forced to live.

The Age of 'Infopolitics' - NYTimes.com - 0 views

  • we need a new way of thinking about our informational milieu. What we need is a concept of infopolitics that would help us understand the increasingly dense ties between politics and information
  • Infopolitics encompasses not only traditional state surveillance and data surveillance, but also “data analytics” (the techniques that enable marketers at companies like Target to detect, for instance, if you are pregnant), digital rights movements (promoted by organizations like the Electronic Frontier Foundation), online-only crypto-currencies (like Bitcoin or Litecoin), algorithmic finance (like automated micro-trading) and digital property disputes (from peer-to-peer file sharing to property claims in the virtual world of Second Life)
  • Surveying this iceberg is crucial because atop it sits a new kind of person: the informational person. Politically and culturally, we are increasingly defined through an array of information architectures: highly designed environments of data, like our social media profiles, into which we often have to squeeze ourselves

  • We have become what the privacy theorist Daniel Solove calls “digital persons.” As such we are subject to infopolitics (or what the philosopher Grégoire Chamayou calls “datapower,” the political theorist Davide Panagia “datapolitik” and the pioneering thinker Donna Haraway “informatics of domination”).
  • Once fingerprints, biometrics, birth certificates and standardized names were operational, it became possible to implement an international passport system, a social security number and all other manner of paperwork that tells us who someone is. When all that paper ultimately went digital, the reams of data about us became radically more assessable and subject to manipulation,
  • We like to think of ourselves as somehow apart from all this information. We are real — the information is merely about us.
  • But what is it that is real? What would be left of you if someone took away all your numbers, cards, accounts, dossiers and other informational prostheses? Information is not just about you — it also constitutes who you are.
  • We understandably do not want to see ourselves as bits and bytes. But unless we begin conceptualizing ourselves in this way, we leave it to others to do it for us
  • agencies and corporations will continue producing new visions of you and me, and they will do so without our input if we remain stubbornly attached to antiquated conceptions of selfhood that keep us from admitting how informational we already are.
  • What should we do about our Internet and phone patterns’ being fastidiously harvested and stored away in remote databanks where they await inspection by future algorithms developed at the National Security Agency, Facebook, credit reporting firms like Experian and other new institutions of information and control that will come into existence in future decades?
  • What bits of the informational you will fall under scrutiny? The political you? The sexual you? What next-generation McCarthyisms await your informational self? And will those excesses of oversight be found in some Senate subcommittee against which we democratic citizens might hope to rise up in revolt — or will they lurk among algorithmic automatons that silently seal our fates in digital filing systems?

Brain Connectivity Study Reveals Striking Differences Between Men and Women - 0 views

  • In contrast, in females, the wiring goes between the left and right hemispheres, suggesting that they facilitate communication between the analytical and intuition.
  • “These maps show us a stark difference--and complementarity--in the architecture of the human brain that helps provide a potential neural basis as to why men excel at certain tasks, and women at others,” said Verma.
  • In the study, the researchers found that females displayed greater connectivity in the supratentorial region, which contains the cerebrum, the largest part of the brain, between the left and right hemispheres. Males, on the other hand, displayed greater connectivity within each hemisphere. 
  • ...3 more annotations...
  • The female connections likely facilitate integration of the analytic and sequential processing modes of the left hemisphere with the spatial, intuitive information processing modes of the right side.
  • the opposite prevailed in the cerebellum, the part of the brain that plays a major role in motor control,
  • Females outperformed males on attention, word and face memory, and social cognition tests.

How the Brain Creates Personality: A New Theory - Stephen M. Kosslyn and G. Wayne Mille... - 0 views

  • It is possible to examine any object—including a brain—at different levels
  • if we want to know how the brain gives rise to thoughts, feelings, and behaviors, we want to focus on the bigger picture of how its structure allows it to store and process information—the architecture, as it were. To understand the brain at this level, we don’t have to know everything about the individual connections among brain cells or about any other biochemical process.
  • top parts and the bottom parts of the brain have differ­ent functions. The top brain formulates and executes plans (which often involve deciding where to move objects or how to move the body in space), whereas the bottom brain classifies and interprets incoming information about the world. The two halves always work together;
  • ...9 more annotations...
  • You have probably heard of this theory, in which the left and right halves of the brain are characterized, respectively, as logical versus intuitive, verbal versus perceptual, analytic versus synthetic, and so forth. The trouble is that none of these sweeping generalizations has stood up to careful scientific scrutiny. The dif­ferences between the left and right sides of the brain are nuanced, and simple, sweeping dichotomies do not in fact explain how the two sides function.
  • top and bottom portions of the brain have very different functions. This fact was first discovered in the context of visual perception, and it was supported in 1982 in a landmark report by National Medal of Science winner Mortimer Mishkin and Leslie G. Ungerleider, of the National Institute of Mental Health.
  • scientists trained monkeys to perform two tasks. In the first task, the monkeys had to learn to recognize which of two shapes concealed a bit of food.
  • These functions occur relatively close to where neural connec­tions deliver inputs from the eyes and ears—but processing doesn’t just stop there.
  • top parts of our frontal lobe can take into account the confluence of information about “what’s out there,” our emo­tional reactions to it, and our goals.
  • Four distinct cognitive modes emerge from how the top-brain and bottom-brain systems can interac
  • The two systems always work together. You use the top brain to decide to walk over to talk to your friend only after you know who she is (courtesy of the bottom brain). And after talking to her, you formulate another plan, to enter the date and time in your calendar, and then you need to monitor what hap­pens (again using the bottom brain) as you try to carry out this plan (a top-brain activity).
  • speak of differences in the degree to which a person relies on the top-brain and bottom-brain systems, we are speaking of differences in this second kind of utilization, in the kind of processing that’s not simply dictated by a given situation. In this sense, you can rely on one or the other brain system to a greater or lesser degree.
  • The degree to which you tend to use each system will affect your thoughts, feel­ings, and behavior in profound ways. The notion that each system can be more or less highly utilized, in this sense is the foundation of the Theory of Cognitive Modes.

Gut Bacteria Might Guide The Workings Of Our Minds : Shots - Health News : NPR - 0 views

  • Turns out you really can have a gut feeling about something, because evidence has been mounting that those microbes in the body may be important for our emotional health as well as our physical health.
  • PRIA TEWARI: Growing up in India we believe that what you eat influences your thoughts.
  • MAYER: We found that the type of community you have, of microbes you have in your gut, is reflected in some ways in some basic architectural aspects of the brain.
  • ...7 more annotations...
  • STEIN: The brain connections of people whose microbes are dominated by one species of bacteria look different than those of people whose microbes are dominated by another species. That suggests that the specific mix of microbes in our guts helps determine what kinds of brains we have, how our brain circuits develop, how they're wired.
  • STEIN: It worked the other way around too. The bold mice became timid when they got the microbes of anxious ones. Aggressive mice also calmed down when the scientists altered their microbes by changing their diet, feeding them probiotics, or dosing them with antibiotics.
  • This could help explain why some people are born with brains that don't work the way they're supposed to, causing problems like autism, anxiety, depression.
  • COLLINS: And this resulted in a change in behavior. The mice became a little bit less anxious, a little bit more gregarious.
  • They did things like replace the gut bacteria of anxious mice with bacteria from fearless mice.
  • STEIN: Finally, these scientists figured out how the microbes in the guts of the mice were communicating with their brains - by sending signals up a big nerve known as the vagus nerve.
  • All this is raising the possibility that scientists could create drugs that mimic these signals. Or just give people the good bacteria - probiotics - to prevent or treat problems involving the brain.

Book Club: A Guide To Living « The Dish - 0 views

  • He proves nothing that he doesn’t simultaneously subvert a little; he makes no over-arching argument about the way humans must live; he has no logician’s architecture or religious doctrine. He slips past all those familiar means of telling other people what’s good for them, and simply explains what has worked for him and others and leaves the reader empowered to forge her own future
  • You can see its eccentric power by considering the alternative ways of doing what Montaigne was doing. Think of contemporary self-help books – and all the fake certainty and rigid formulae they contain. Or think of a hideous idea like “the purpose-driven life” in which everything must be forced into the box of divine guidance in order to really live at all. Think of the stringency of Christian disciplines – say, the spiritual exercises of Ignatius of Loyola – and marvel at how Montaigne offers an entirely different and less compelling way to live. Think of the rigidity of Muslim practice and notice how much lee-way Montaigne gives to sin
  • This is a non-philosophical philosophy. It is a theory of practical life as told through one man’s random and yet not-so-random reflections on his time on earth. And it is shot through with doubt. Even the maxims that Montaigne embraces for living are edged with those critical elements of Montaigne’s thought that say “as far as I know”
  • ...4 more annotations...
  • Is this enough? Or is it rather a capitulation to relativism, a manifesto for political quietism, a worldview that treats injustice as something to be abhorred but not constantly fought against? This might be seen as the core progressive objection to the way of Montaigne. Or is his sensibility in an age of religious terror and violence and fanaticism the only ultimate solution we have?
  • here’s what we do know. We are fallible beings; we have nothing but provisional knowledge; and we will die. And this is enough. This does not mean we should give up inquiring or seeking to understand. Skepticism is not nihilism. It doesn’t posit that there is no truth; it merely notes that if truth exists, it is inherently beyond our ultimate grasp. And accepting those limits is the first step toward sanity, toward getting on with life. This is what I mean by conservatism.
  • you can find in philosophy any number of clues about how to live; you can even construct them into an ideology that explains all of human life and society – like Marxism or free market fundamentalism or a Nietzschean will to power. But as each totalist system broke down upon my further inspection, I found myself returning to Montaigne and the tradition of skepticism he represents
  • If I were to single out one theme of Montaigne’s work that has stuck with me, it would be this staring of death in the face, early and often, and never flinching. It is what our culture refuses to do much of the time, thereby disempowering us in the face of our human challenges.

The 50 Greatest Breakthroughs Since the Wheel - James Fallows - The Atlantic - 0 views

  • Some questions you ask because you want the right answer. Others are valuable because no answer is right; the payoff comes from the range of attempts.
  • That is the diversity of views about the types of historical breakthroughs that matter, with a striking consensus on whether the long trail of innovation recorded here is now nearing its end.
  • The clearest example of consensus was the first item on the final compilation, the printing press
  • ...27 more annotations...
  • Leslie Berlin, a historian of business at Stanford, organized her nominations not as an overall list but grouped into functional categories.
  • Innovations that expand the human intellect and its creative, expressive, and even moral possibilities.
  • Innovations that are integral to the physical and operating infrastructure of the modern world
  • Innovations that enabled the Industrial Revolution and its successive waves of expanded material output
  • Innovations extending life, to use Leslie Berlin’s term
  • Innovations that allowed real-time communication beyond the range of a single human voice
  • Innovations in the physical movement of people and goods.
  • Organizational breakthroughs that provide the software for people working and living together in increasingly efficient and modern ways
  • For our era, the major problems that technology has helped cause, and that faster innovation may or may not correct, are environmental, demographic, and socioeconomic.
  • Any collection of 50 breakthroughs must exclude 50,000 more.
  • We learn, finally, why technology breeds optimism, which may be the most significant part of this exercise.
  • Popular culture often lionizes the stars of discovery and invention
  • Finally, and less prominently than we might have found in 1950 or 1920—and less prominently than I initially expected—we have innovations in killing,
  • people who have thought deeply about innovation’s sources and effects, like our panelists, were aware of the harm it has done along with the good.
  • “Does innovation raise the wealth of the planet? I believe it does,” John Doerr, who has helped launch Google, Amazon, and other giants of today’s technology, said. “But technology left to its own devices widens rather than narrows the gap between the rich and the poor.”
  • Are today’s statesmen an improvement over those of our grandparents’ era? Today’s level of public debate? Music, architecture, literature, the fine arts—these and other manifestations of world culture continually change, without necessarily improving. Tolstoy and Dostoyevsky, versus whoever is the best-selling author in Moscow right now?
  • The argument that a slowdown might happen, and that it would be harmful if it did, takes three main forms.
  • Some societies have closed themselves off and stopped inventing altogether:
  • By failing to move forward, they inevitably moved backward relative to their rivals and to the environmental and economic threats they faced. If the social and intellectual climate for innovation sours, what has happened before can happen again.
  • visible slowdown in the pace of solutions that technology offers to fundamental problems.
  • a slowdown in, say, crop yields or travel time is part of a general pattern of what economists call diminishing marginal returns. The easy improvements are, quite naturally, the first to be made; whatever comes later is slower and harder.
  • America’s history as a nation happens to coincide with a rare moment in technological history now nearing its end. “There was virtually no economic growth before 1750,” he writes in a recent paper.
  • “We can be concerned about the last 1 percent of an environment for innovation, but that is because we take everything else for granted,” Leslie Berlin told me.
  • This reduction in cost, he says, means that the next decade should be a time of “amazing advances in understanding the genetic basis of disease, with especially powerful implications for cancer.”
  • the very concept of an end to innovation defied everything they understood about human inquiry. “If you look just at the 20th century, the odds against there being any improvement in living standards are enormous,”
  • “Two catastrophic world wars, the Cold War, the Depression, the rise of totalitarianism—it’s been one disaster after another, a sequence that could have been enough to sink us back into barbarism. And yet this past half century has been the fastest-ever time of technological growth. I see no reason why that should be slowing down.”
  • “I am a technological evolutionist,” he said. “I view the universe as a phase-space of things that are possible, and we’re doing a random walk among them. Eventually we are going to fill the space of everything that is possible.”

A German Writer Translates a Puzzling Illness Into a Best-Selling Book - The New York T... - 0 views

  • Back in 2007, after a series of mostly ineffective treatments prescribed by doctors, Ms. Enders, then 17, decided to take matters into her own hands. Convinced that the illness was somehow associated with her intestines, she pored over gastroenterological research, consumed probiotic bacterial cultures meant to aid digestion and tried out mineral supplements.
  • The experiments worked (although she is not sure which one did the trick), leaving her with healthy skin and a newfound interest in her intestines. “I experienced with my own body that knowledge is power,” she writes of the episode in “Gut: The Inside Story of Our Body’s Most Underrated Organ,”

Teachers - Will We Ever Learn? - NYTimes.com - 0 views

  • America’s overall performance in K-12 education remains stubbornly mediocre.
  • The debate over school reform has become a false polarization
  • teaching is a complex activity that is hard to direct and improve from afar. The factory model is appropriate to simple work that is easy to standardize; it is ill suited to disciplines like teaching that require considerable skill and discretion.
  • ...13 more annotations...
  • In the nations that lead the international rankings — Singapore, Japan, South Korea, Finland, Canada — teachers are drawn from the top third of college graduates, rather than the bottom 60 percent as is the case in the United States. Training in these countries is more rigorous, more tied to classroom practice and more often financed by the government than in America. There are also many fewer teacher-training institutions, with much higher standards.
  • By these criteria, American education is a failed profession. There is no widely agreed-upon knowledge base, training is brief or nonexistent, the criteria for passing licensing exams are much lower than in other fields, and there is little continuous professional guidance. It is not surprising, then, that researchers find wide variation in teaching skills across classrooms; in the absence of a system devoted to developing consistent expertise, we have teachers essentially winging it as they go along, with predictably uneven results.
  • Teaching requires a professional model, like we have in medicine, law, engineering, accounting, architecture and many other fields. In these professions, consistency of quality is created less by holding individual practitioners accountable and more by building a body of knowledge, carefully training people in that knowledge, requiring them to show expertise before they become licensed, and then using their professions’ standards to guide their work.
  • Teachers in leading nations’ schools also teach much less than ours do. High school teachers provide 1,080 hours per year of instruction in America, compared with fewer than 600 in South Korea and Japan, where the balance of teachers’ time is spent collaboratively on developing and refining lesson plans
  • These countries also have much stronger welfare states; by providing more support for students’ social, psychological and physical needs, they make it easier for teachers to focus on their academic needs.
  • hese elements create a virtuous cycle: strong academic performance leads to schools with greater autonomy and more public financing, which in turn makes education an attractive profession for talented people.
  • In America, both major teachers’ unions and the organization representing state education officials have, in the past year, called for raising the bar for entering teachers; one of the unions, the American Federation of Teachers, advocates a “bar exam.”
  • Ideally the exam should not be a one-time paper-and-pencil test, like legal bar exams, but a phased set of milestones to be attained over the first few years of teaching. Akin to medical boards, they would require prospective teachers to demonstrate subject and pedagogical knowledge — as well as actual teaching skill.
  • We let doctors operate, pilots fly, and engineers build because their fields have developed effective ways of certifying that they can do these things. Teaching, on the whole, lacks this specialized knowledge base; teachers teach based mostly on what they have picked up from experience and from their colleagues.
  • other fields spend 5 percent to 15 percent of their budgets on research and development, while in education, it is around 0.25 percent
  • Education-school researchers publish for fellow academics; teachers develop practical knowledge but do not evaluate or share it; commercial curriculum designers make what districts and states will buy, with little regard for quality.
  • Early- to mid-career teachers need time to collaborate and explore new directions — having mastered the basics, this is the stage when they can refine their skills. The system should reward master teachers with salaries commensurate with leading professionals in other fields.
  • research suggests that the labels don’t matter — there are good and bad programs of all types, including university-based ones. The best programs draw people who majored as undergraduates in the subjects they wanted to teach; focus on extensive clinical practice rather than on classroom theory; are selective in choosing their applicants rather than treating students as a revenue stream; and use data about how their students fare as teachers to assess and revise their practice.

What Would Plato Tweet? - NYTimes.com - 1 views

  • In a mere couple of centuries, Greek speakers went from anomie and illiteracy, lacking even an alphabet, to Aeschylus and Aristotle. They invented not only the discipline of philosophy, but also science, mathematics, the study of history (as opposed to mere chronicles) and that special form of government they called democracy — literally rule of the people (though it goes without saying that “the people” didn’t include women and slaves). They also produced timeless art, architecture, poetry and drama.
  • The more outstanding you were, the more mental replication of you there would be, and the more replication, the more you mattered.
  • Kleos lay very near the core of the Greek value system. Their value system was at least partly motivated, as perhaps all value systems are partly motivated, by the human need to feel as if our lives matter

  • Greek philosophy also represented a departure from its own culture. Mattering wasn’t acquired by gathering attention of any kind, mortal or immortal. Acquiring mattering was something people had to do for themselves, cultivating such virtuous qualities of character as justice and wisdom. They had to put their own souls in order.
  • the Ivrim, the Hebrews, apparently from their word for “over,” since they were over on the other side of the Jordan
  • the one and only God, the Master of the Universe, providing the foundation for both the physical world without and the moral world within. From his position of remotest transcendence, this god nevertheless maintains a rapt interest in human concerns, harboring many intentions directed at us, his creations, who embody nothing less than his reasons for going to the trouble of creating the world ex nihilo
  • what the Greeks had called kleos. The word comes from the old Homeric word for “I hear,” and it meant a kind of auditory renown. Vulgarly speaking, it was fame. But it also could mean the glorious deed that merited the fame, as well as the poem that sang of the deed and so produced the fame.
  • Over the centuries, philosophy, perhaps aided by religion, learned to abandon entirely the flawed Greek presumption that only extraordinary lives matter. This was progress of the philosophical variety, subtler than the dazzling triumphs of science, but nevertheless real. Philosophy has laboriously put forth arguments that have ever widened the sphere of mattering.
  • We’ve come a long way from the kleos of Greeks, with its unexamined presumption that mattering is inequitably distributed among us, with the multireplicated among us mattering more.
  • our culture has, with the dwindling of theism, returned to the answer to the problem of mattering that Socrates and Plato judged woefully inadequate.

Our Machine Masters - NYTimes.com - 0 views

  • the smart machines of the future won’t be humanlike geniuses like HAL 9000 in the movie “2001: A Space Odyssey.” They will be more modest machines that will drive your car, translate foreign languages, organize your photos, recommend entertainment options and maybe diagnose your illnesses. “Everything that we formerly electrified we will now cognitize,” Kelly writes. Even more than today, we’ll lead our lives enmeshed with machines that do some of our thinking tasks for us.
  • This artificial intelligence breakthrough, he argues, is being driven by cheap parallel computation technologies, big data collection and better algorithms. The upshot is clear, “The business plans of the next 10,000 start-ups are easy to forecast: Take X and add A.I.”

  • Advances in artificial intelligence will accelerate this centralizing trend. That’s because A.I. companies will be able to reap the rewards of network effects. The bigger their network and the more data they collect, the more effective and attractive they become.
  • As a result, our A.I. future is likely to be ruled by an oligarchy of two or three large, general-purpose cloud-based commercial intelligences.”
  • engineers at a few gigantic companies will have vast-though-hidden power to shape how data are collected and framed, to harvest huge amounts of information, to build the frameworks through which the rest of us make decisions and to steer our choices. If you think this power will be used for entirely benign ends, then you have not read enough history.
  • The second implication is philosophical. A.I. will redefine what it means to be human. Our identity as humans is shaped by what machines and other animals can’t do
  • On the other hand, machines cannot beat us at the things we do without conscious thinking: developing tastes and affections, mimicking each other and building emotional attachments, experiencing imaginative breakthroughs, forming moral sentiments.
  • For the last few centuries, reason was seen as the ultimate human faculty. But now machines are better at many of the tasks we associate with thinking — like playing chess, winning at Jeopardy, and doing math.
  • In the age of smart machines, we’re not human because we have big brains. We’re human because we have social skills, emotional capacities and moral intuitions.
  • I could paint two divergent A.I. futures, one deeply humanistic, and one soullessly utilitarian.
  • In the cold, utilitarian future, on the other hand, people become less idiosyncratic. If the choice architecture behind many decisions is based on big data from vast crowds, everybody follows the prompts and chooses to be like each other. The machine prompts us to consume what is popular, the things that are easy and mentally undemanding.
  • In this future, there is increasing emphasis on personal and moral faculties: being likable, industrious, trustworthy and affectionate. People are evaluated more on these traits, which supplement machine thinking, and not the rote ones that duplicate it
  • In the humanistic one, machines liberate us from mental drudgery so we can focus on higher and happier things. In this future, differences in innate I.Q. are less important. Everybody has Google on their phones so having a great memory or the ability to calculate with big numbers doesn’t help as much.
  • In the current issue of Wired, the technology writer Kevin Kelly says that we had all better get used to this level of predictive prowess. Kelly argues that the age of artificial intelligence is finally at hand.
