Eric Kandel's Visions - The Chronicle Review - The Chronicle of Higher Education - 0 views

  • Judith, "barely clothed and fresh from the seduction and slaying of Holofernes, glows in her voluptuousness. Her hair is a dark sky between the golden branches of Assyrian trees, fertility symbols that represent her eroticism. This young, ecstatic, extravagantly made-up woman confronts the viewer through half-closed eyes in what appears to be a reverie of orgasmic rapture," writes Eric Kandel in his new book, The Age of Insight. Wait a minute. Writes who? Eric Kandel, the Nobel-winning neuroscientist who's spent most of his career fixated on the generously sized neurons of sea snails
  • Kandel goes on to speculate, in a bravura paragraph a few hundred pages later, on the exact neurochemical cognitive circuitry of the painting's viewer:
  • "At a base level, the aesthetics of the image's luminous gold surface, the soft rendering of the body, and the overall harmonious combination of colors could activate the pleasure circuits, triggering the release of dopamine. If Judith's smooth skin and exposed breast trigger the release of endorphins, oxytocin, and vasopressin, one might feel sexual excitement. The latent violence of Holofernes's decapitated head, as well as Judith's own sadistic gaze and upturned lip, could cause the release of norepinephrine, resulting in increased heart rate and blood pressure and triggering the fight-or-flight response. In contrast, the soft brushwork and repetitive, almost meditative, patterning may stimulate the release of serotonin. As the beholder takes in the image and its multifaceted emotional content, the release of acetylcholine to the hippocampus contributes to the storing of the image in the viewer's memory. What ultimately makes an image like Klimt's 'Judith' so irresistible and dynamic is its complexity, the way it activates a number of distinct and often conflicting emotional signals in the brain and combines them to produce a staggeringly complex and fascinating swirl of emotions."

  • His key findings on the snail, for which he shared the 2000 Nobel Prize in Physiology or Medicine, showed that learning and memory change not the neuron's basic structure but rather the nature, strength, and number of its synaptic connections. Further, through focus on the molecular biology involved in a learned reflex like Aplysia's gill retraction, Kandel demonstrated that experience alters nerve cells' synapses by changing their pattern of gene expression. In other words, learning doesn't change what neurons are, but rather what they do.
  • In Search of Memory (Norton), Kandel offered what sounded at the time like a vague research agenda for future generations in the budding field of neuroaesthetics, saying that the science of memory storage lay "at the foothills of a great mountain range." Experts grasp the "cellular and molecular mechanisms," he wrote, but need to move to the level of neural circuits to answer the question, "How are internal representations of a face, a scene, a melody, or an experience encoded in the brain?
  • Since giving a talk on the matter in 2001, he has been piecing together his own thoughts in relation to his favorite European artists
  • The field of neuroaesthetics, says one of its founders, Semir Zeki, of University College London, is just 10 to 15 years old. Through brain imaging and other studies, scholars like Zeki have explored the cognitive responses to, say, color contrasts or ambiguities of line or perspective in works by Titian, Michelangelo, Cubists, and Abstract Expressionists. Researchers have also examined the brain's pleasure centers in response to appealing landscapes.
  • it is fundamental to an understanding of human cognition and motivation. Art isn't, as Kandel paraphrases a concept from the late philosopher of art Denis Dutton, "a byproduct of evolution, but rather an evolutionary adaptation—an instinctual trait—that helps us survive because it is crucial to our well-being." The arts encode information, stories, and perspectives that allow us to appraise courses of action and the feelings and motives of others in a palatable, low-risk way.
  • "as far as activity in the brain is concerned, there is a faculty of beauty that is not dependent on the modality through which it is conveyed but which can be activated by at least two sources—musical and visual—and probably by other sources as well." Specifically, in this "brain-based theory of beauty," the paper says, that faculty is associated with activity in the medial orbitofrontal cortex.
  • It also enables Kandel—building on the work of Gombrich and the psychoanalyst and art historian Ernst Kris, among others—to compare the painters' rendering of emotion, the unconscious, and the libido with contemporaneous psychological insights from Freud about latent aggression, pleasure and death instincts, and other primal drives.
  • Kandel views the Expressionists' art through the powerful multiple lenses of turn-of-the-century Vienna's cultural mores and psychological insights. But then he refracts them further, through later discoveries in cognitive science. He seeks to reassure those who fear that the empirical and chemical will diminish the paintings' poetic power. "In art, as in science," he writes, "reductionism does not trivialize our perception—of color, light, and perspective—but allows us to see each of these components in a new way. Indeed, artists, particularly modern artists, have intentionally limited the scope and vocabulary of their expression to convey, as Mark Rothko and Ad Reinhardt do, the most essential, even spiritual ideas of their art."
  • The author of a classic textbook on neuroscience, he seems here to have written a layman's cognition textbook wrapped within a work of art history.
  • "our initial response to the most salient features of the paintings of the Austrian Modernists, like our response to a dangerous animal, is automatic. ... The answer to James's question of how an object simply perceived turns into an object emotionally felt, then, is that the portraits are never objects simply perceived. They are more like the dangerous animal at a distance—both perceived and felt."
  • If imaging is key to gauging therapeutic practices, it will be key to neuroaesthetics as well, Kandel predicts—a broad, intense array of "imaging experiments to see what happens with exaggeration, distorted faces, in the human brain and the monkey brain," viewers' responses to "mixed eroticism and aggression," and the like.
  • while the visual-perception literature might be richer at the moment, there's no reason that neuroaesthetics should restrict its emphasis to the purely visual arts at the expense of music, dance, film, and theater.
  • although Kandel considers The Age of Insight to be more a work of intellectual history than of science, the book summarizes centuries of research on perception. And so you'll find, in those hundreds of pages between Kandel's introduction to Klimt's "Judith" and the neurochemical cadenza about the viewer's response to it, dossiers on vision as information processing; the brain's three-dimensional-space mapping and its interpretations of two-dimensional renderings; face recognition; the mirror neurons that enable us to empathize and physically reflect the affect and intentions we see in others; and many related topics. Kandel elsewhere describes the scientific evidence that creativity is nurtured by spells of relaxation, which foster a connection between conscious and unconscious cognition.
  • Zeki's message to art historians, aesthetic philosophers, and others who chafe at that idea is twofold. The more diplomatic pitch is that neuroaesthetics is different, complementary, and not oppositional to other forms of arts scholarship. But "the stick," as he puts it, is that if arts scholars "want to be taken seriously" by neurobiologists, they need to take advantage of the discoveries of the past half-century. If they don't, he says, "it's a bit like the guys who said to Galileo that we'd rather not look through your telescope."
  • Matthews, a co-author of The Bard on the Brain: Understanding the Mind Through the Art of Shakespeare and the Science of Brain Imaging (Dana Press, 2003), seems open to the elucidations that science and the humanities can cast on each other. The neural pathways of our aesthetic responses are "good explanations," he says. But "does one [type of] explanation supersede all the others? I would argue that they don't, because there's a fundamental disconnection still between ... explanations of neural correlates of conscious experience and conscious experience" itself.
  • There are, Matthews says, "certain kinds of problems that are fundamentally interesting to us as a species: What is love? What motivates us to anger?" Writers put their observations on such matters into idiosyncratic stories, psychologists conceive their observations in a more formalized framework, and neuroscientists like Zeki monitor them at the level of functional changes in the brain. All of those approaches to human experience "intersect," Matthews says, "but no one of them is the explanation."
  • "Conscious experience," he says, "is something we cannot even interrogate in ourselves adequately. What we're always trying to do in effect is capture the conscious experience of the last moment. ... As we think about it, we have no way of capturing more than one part of it."
  • Kandel sees art and art history as "parent disciplines" and psychology and brain science as "antidisciplines," to be drawn together in an E.O. Wilson-like synthesis toward "consilience as an attempt to open a discussion between restricted areas of knowledge." Kandel approvingly cites Stephen Jay Gould's wish for "the sciences and humanities to become the greatest of pals ... but to keep their ineluctably different aims and logics separate as they ply their joint projects and learn from each other."

How Life Began: New Clues | TIME.com - 0 views

  • Astronomers recently announced that there could be an astonishing 20 billion Earthlike planets in the Milky Way
  • How abundant life actually is, however, hinges on one crucial factor: given the right conditions and the right raw materials,
  • what is the mathematical likelihood that life will actually would arise?
  • ...8 more annotations...
  • biology would have to be popping up all over the place.
  • Andrew Ellington, of the Center for Systems and Synthetic Biology at the University of Texas, Austin, “I can’t tell you what the probability is. It’s a chapter of the story that’s pretty much blank.”
  • Given that rather bleak-sounding assessment, it may be surprising to learn that Ellington is actually pretty upbeat. But that’s how he and two colleagues come across in a paper in the latest Science. The crucial step from nonliving stuff to a live cell is still a mystery, they acknowledge, but the number of pathways a mix of inanimate chemicals could have taken to reach the threshold of the living turns out to be many and varied. “It’s difficult to say exactly how things did occur,” says Ellington. “But there are many ways it could have occurred.
  • The first stab at answering the question came all the way back in the 1950s, when chemists Stanley Miller and Harold Urey passed an electrical spark through a beaker containing methane, ammonia, water vapor and hydrogen, thought at the time to represent Earth’s primordial atmosphere.
  • Scientists have learned so much, in fact, that the number of places life might have begun has grown to include such disparate locations as the hydrothermal vents at the bottom of the ocean; beds of clay; the billowing clouds of gas emerging from volcanoes; and the spaces in between ice crystals.
  • The number of ideas about how the key step from organic chemicals to living organisms might have been taken has multiplied as well: there’s the “RNA world hypothesis” and the “lipid world hypothesis” and the “iron-sulfur world hypothesis” and more, all of them dependent on a particular set of chemical circumstances and a particular set of dynamics and all highly speculative.
  • “Maybe when they do,” says Ellington, “we’ll all do a face-plant because it turns out to be so obvious in retrospect.” But even if they succeed, it will only prove that a manufactured cell could represent the earliest life forms, not that it actually does. “It will be a story about what we think might have happened, but it will still be a story.”
  • The story Ellington and his colleagues have been able to tell already, however, is a reason for optimism. We still don’t know the odds that life will arise under the right conditions. But the underlying biochemistry is abundantly, ubiquitously available—and it would take an awfully perverse universe to take things so far only to shut them down at the last moment.

Hunting boosts lizard numbers in Australian desert | Science News - 0 views

  • The presence of humans rarely improves the lives of neighboring species. Yet a study shows that indigenous Australian hunters create prime habitat for a desert-dwelling lizard.
  • The frequent burning creates a patchy mosaic of charred lands and vegetation springing up in various stages of regrowth.
  • The lizards may prefer these edges because emerging vegetation from recently burned patches bears more food, the researchers speculate.

  • Indeed, when the Martu and other desert foragers were forced to leave their lands between the 1950s and 1970s, surveys showed that 10 to 20 native mammal species went extinct and the numbers of 43 others dropped sharply
  • The research compellingly argues that “small-scale human societies can actually exist in an ecosystem without damaging it over a very long period of time,” says archeologist Bruce Smith of the Smithsonian National Museum of Natural History. “It’s just wonderful science.”

As Researchers Turn to Google, Libraries Navigate the Messy World of Discovery Tools - ... - 0 views

  • a major change is under way in how libraries organize information. Instead of bewildering users with a bevy of specialized databases—books here, articles there—many libraries are bulldozing their digital silos. They now offer one-stop search boxes that comb entire collections, Google style.
  • one fear is that firms could favor their own content in results.
  • Another is that discovery software, by sluicing content together, could deluge users with less-appropriate resources
  • ...8 more annotations...
  • the rollout of one-stop search tools is "really intentionally trying to change the way people do research,"
  • "That’s bound to change what people find."
  • Vendors of discovery tools will make deals with providers that sell content to libraries, he says, so that content can be represented in the discovery tools’ indexes and made available for search. (Beyond products from Ebsco and ProQuest, other major tools in this genre, known as "web scale" or "index based" discovery, include Primo, from Ex Libris, and WorldCat Discovery Services, from OCLC.)
  • Mr. Asher’s experiment discovered that default settings of the tools had a major effect on what resources students chose. Working with Google Scholar, which is integrated with Google Books, students used more books. With Summon, they used a lot of shorter newspaper and magazine articles. With ­Ebsco Discovery Service, they used more journals, which meant they scored highest under the study’s rating rubric.
  • Mr. Asher believes that "it’s a logical impossibility to create a querying tool that doesn’t have any form of bias." He speculates that discovery vendors may have better information about their own content, boosting certain articles higher in results.
  • the competition for student and faculty attention has only intensified since 2004, when Google’s "simple way to broadly search for scholarly literature" made its debut. That free service, called Google Scholar, has many fans in academe.
  • Mr. Asher is familiar with the criticisms of Google Scholar. After all, his own study listed them: "limited advanced search functionality, incomplete or inaccurate metadata, inflated citation counts, lack of usage statistics, and inconsistent coverage across disciplines."
  • "I kind of hate to say it, since I am a librarian," he says. "We pay a lot of money for discovery tools. And then I go off and just use Google Scholar."

The bright side of sadness - 1 views

  • Thomas Jefferson defended the right to pursue happiness in the Declaration of Independence.
  • “Bad moods are seen in our happiness-focused culture as representing a problem, but we need to be aware that temporary, mild negative feelings have important benefits,”
  • One investigation found that people in sad moods have an advantage remembering the details of unusual incidents that they have witnessed. And a little gloominess could help job applicants; lousy moods cut down on the tendency to stereotype others, thus boosting the accuracy of first impressions.
  • ...18 more annotations...
  • Growing evidence suggests that gloomy moods improve key types of thinking and behavior, Forgas asserts in a new review paper aptly titled “Don’t worry, be sad!” For good evolutionary reasons, positive and negative moods subtly recruit thinking styles suited to either benign or troubling situations,
  • Alternatively, good moods trigger a loose mode of thought conducive to creativity and seeing the big picture. Happiness signals that a situation is safe, or at least not immediately threatening,
  • Whether good or bad, moods are relatively low-intensity, background feelings that can last for anywhere from a few minutes to the whole day. A person may feel somewhat good or bad, happy or sad, without knowing why or even being aware of such moods.
  • On “good” days, he reasoned, everything just felt right without any past triumphs coming to mind. On “bad” days, life felt lousy in the moment, without any tragic memories returning for an encore.
  • Individuals aren’t slaves to their moods, Schwarz cautions. A sad person can think outside the box if necessary, say, to solve problems at work. And a happy person can accurately fill out tax forms or complete other detail-heavy tasks.
  • Moods provide surprisingly keen insights into one’s environment, the team concluded.
  • By embracing their moods, superior forecasters gained unconscious access to a vast amount of learned information that informed their predictions, Pham speculated.
  • Many emotion theorists now agree that negative moods direct attention to tasks at hand and promote analytical thinking, whereas positive moods broaden attention and prompt original thinking. Researchers in a field dubbed “positive psychology” have put a lot of recent focus on exploring how happiness profits mind and body.
  • Sad moods also improve eyewitness memory, apparently by lowering the tendency to incorporate false and misleading details into accounts of what was observed. In a 2005 study in the Journal of Experimental Social Psychology, college students witnessed a staged altercation between a lecturer and a woman who angrily interrupted the talk.
  • Sad moods can also make first impressions of others more reliable,
  • Sad folks took longer to read and rate the essays than happy and neutral participants did. That’s probably because feeling sad fostered a more careful appraisal of essays and photos, Forgas suggests. As a result, he proposes, sad volunteers largely rejected the stereotype of philosophers as tweedy, professorial men, helping to minimize the halo effect.
  • In these experiments, moods were induced either by having participants watch happy or sad film clips or by falsely telling volunteers that they had scored extremely well or poorly on a test of spatial abilities.
  • In both conditions, raters determined that sad volunteers communicated more information relevant to the movie scenes and less unrelated information than the other two groups did, especially the happy folks. Those in a sad mood were especially good at keeping accounts brief, clear and to the point.
  • Moods were induced after participants watched movie clips but before they described the scenes, ensuring that the clips didn’t sway their manipulated moods.
  • Sad feelings may influence communication differently in situations where conversation
  • But moods may not engage specific mental strategies as proposed
  • If these findings hold up, happy and sad moods simply signal whether or not to change one’s current thinking style, Huntsinger says, rather than indicating whether to adopt an analytical or playful thinking style. Researchers have yet to test which of these two possibilities best explains mood-related behaviors.

Researchers Link Feelings Of Disgust And Ethical Behavior : NPR - 0 views

  • Next, we examine what happens when you feel disgusted. Maybe you've come across rotting food or a bathroom that's dirty. Well, there's new research exploring how that kind of experience affects the ethical choices you might make afterward.
  • Disgust seems to make people behave in more unethical ways, Steve. This is research by Karen Winterich, Vikas Mittal and Andrea Morales. They conducted a series of experiments. In one of them, they had volunteers view a scene from the movie "Trainspotting," and the movie showed a disgustingly dirty toilet. Other volunteers watched a documentary about a coral reef. The researchers find that volunteers who watched the disgusting scene are more likely to cheat a partner in a game they play right afterwards.
  • And they're arguing that the feeling of disgust triggers feelings of self-preservation - wanting to protect yourself from the thing that's disgusting. And the researchers are speculating that these feelings of self-preservation translate more generally into feelings of selfishness, of looking out for yourself and this produces a willingness to cheat.

Feeling Sad Makes Us More Creative | Wired Science | Wired.com - 0 views

  • For thousands of years, people have speculated that there’s some correlation between sadness and creativity, so that people who are a little bit miserable (think Van Gogh, or Dylan in 1965, or Virginia Woolf) are also the most innovative.
  • People who received negative feedback created better collages, at least when compared to those who received positive feedback or no feedback at all. Furthermore, those with low baselines of DHEAS proved particularly vulnerable to the external effects of frowns, so that they proved to be the most creative of all.
  • It turns out that states of sadness make us more attentive and detail oriented, more focused
  • ...5 more annotations...
  • angst and sadness promote “information-processing strategies best suited to dealing with more-demanding situations.” This helps explain why test subjects who are melancholy — Forgas induces the mood with a short film about death and cancer — are better at judging the accuracy of rumors and recalling past events; they’re also much less likely to stereotype strangers and make fewer arithmetic mistakes.
  • shoppers in the “low mood” condition remembered nearly four times as many of the trinkets. The wet weather made them sad, and their sadness made them more aware and attentive.
  • There are two important lessons of this research. The first is that our fleeting feelings can change the way we think. While sadness makes us more focused and diligent — the spotlight of attention is sharpened — happiness seems to have the opposite effect, so that good moods make us 20 percent more likely to have a moment of insight. The second takeaway is that many of our creative challenges involve tasks that require diligence, persistence and focus. It’s not easy making a collage or writing a poem or solving a hard technical problem, which is why sometimes being a little miserable can improve our creative performance.
  • Why is mental illness so closely associated with creativity? Andreasen argues that depression is intertwined with a “cognitive style” that makes people more likely to produce successful works of art. In the creative process, Andreasen says, “one of the most important qualities is persistence.”
  • While Andreasen acknowledges the burden of mental illness — she quotes Robert Lowell on depression not being a “gift of the Muse” and describes his reliance on lithium to escape the pain — she argues that many forms of creativity benefit from the relentless focus it makes possible. “Unfortunately, this type of thinking is often inseparable from the suffering,” she says. “If you’re at the cutting edge, then you’re going to bleed.”

Journeys in Alterity: Living According to a Story: A Reflection on Faith - 0 views

  • While I’ve not given up on religion in general or Catholicism in particular, I have said farewell to a specific conception of God, namely God as explanation, and in so doing have joined hands with the atheists and agnostics, if not for the whole of life’s journey, at least for a section of the walk. To clarify, I continue to call God creator and savior, but for me God is not the solution to riddle or a formula. God’s not an answer to scientific inquiry or the end result of metaphysical speculation. God is wholly other than all these lines of human reasoning, all these constructions fashioned to explain the world. My need for God is not the need of a student seeking to explain a mathematical theorem, or the need of an ethicist looking for a basis for good behavior, or someone searching for the last piece to a grand puzzle. The divine isn’t the intellectual rope that ties the whole system together.
  • I find it unwise to hold on to God as an explanation, for sooner or later, what I use God to explain will likely be revealed to have a different basis. If I believe in God because God explains this, that, and the other thing, then I can be almost sure to have a belief that’s not long for this world.
  • What is left of my faith when I have forsaken this idea of God? Having fled from the crumbling ruins of the unmoved mover and the uncaused cause, where do I go in search of the sacred? What conception of the divine lies ahead of me, having kicked the dust from my feet and departed the cities of certainty and supernatural explanation? In short, why do I still believe?
  • ...3 more annotations...
  • I continue to believe, to walk the paths of faith, because I believe a story and continue to choose to believe that story. More precisely, I believe in a grand sacred history that has been given embodiment in a plurality of diverse narratives, epistles, and other sacred writings. I interpret these writings in ways literal and figurative and in ways between. While I don’t look to the books of the New Testament for a historical transcript of the life of Christ, I cling to the hope that they reveal a Divine Person and give flesh and blood anew to impossible events, namely the Incarnation, the Crucifixion, the Resurrection, and the Ascension. On the one hand, my choice to believe the truth of these writings—writings that don’t perfectly add up, to be sure—is a decision to believe that an underlying thematic truth speaks through incredible, fantastical tales told to me by mostly unknown strangers, and passed down to me by figures holy and insidious, self-giving and power-hungry, saintly and vicious. On the other hand, I find some of those who have told and retold these stories, particularly the early Christian martyrs, to be credible witnesses. Those who have given their lives for Christ did so not merely in defiance of their murders, but as an act of witness embraced in the hope that their enemies would become their brothers and sisters. That kind of love strikes me as the height of love. And it’s been known to work wonders.
  • What does my faith give me? It gives me a love story. Not a story that explains love, but a story that gives birth to—and directs my heart, mind, and very being to—the fullest expression and fulfillment of love. It is a story that means everything if it means anything at all. It is a story about what it means to be human and what it means to be divine, both of which tell of what it means to love. My religion tells a love story about a humble God who reveals and who gives humanity, through the sacraments and other gifts, the grace to respond in faith, hope, and most importantly love. In this sacred romance, faith and hope are not ends in themselves, or even eternal things, but the temporal means to an eternal end. That end is love. According to this story, there is no need for faith or hope in heaven, and so you will not find them there. What you will find, if there is anything after death to find or a paradise to find it, is love.
  • My faith doesn’t free me from these unsettling possibilities. It doesn’t whisk me away from the battlefield like a protective Aphrodite. Instead, it fills me with fear and trembling and places me in the hopeless situation of not knowing what I love when I love my God. Yet I would not choose to be anywhere else. I’ve no interest in certainty, gnosis, or other false comforts. Nor do I wish to close the book of faith and place it on the bookshelf, unread, ignored and unlived. I intend to live according to a story I love, to share it with those I love, and to allow it to guide my steps and convert my soul, even though I journey to who knows where. And I intend as well to incline an ear to the voice of alterity, to reasons and rhymes that might expose my faith to its undoing.

The Backfire Effect « You Are Not So Smart - 0 views

  • corrections tended to increase the strength of the participants’ misconceptions if those corrections contradicted their ideologies. People on opposing sides of the political spectrum read the same articles and then the same corrections, and when new evidence was interpreted as threatening to their beliefs, they doubled down. The corrections backfired.
  • Once something is added to your collection of beliefs, you protect it from harm. You do it instinctively and unconsciously when confronted with attitude-inconsistent information. Just as confirmation bias shields you when you actively seek information, the backfire effect defends you when the information seeks you, when it blindsides you. Coming or going, you stick to your beliefs instead of questioning them. When someone tries to correct you, tries to dilute your misconceptions, it backfires and strengthens them instead. Over time, the backfire effect helps make you less skeptical of those things which allow you to continue seeing your beliefs and attitudes as true and proper.

Instead, they said the issue was something science couldn’t understand. When asked about other topics later on, like spanking or astrology, these same people said they no longer trusted research to determine the truth. Rather than shed their belief and face facts, they rejected science altogether.
  • As social media and advertising progresses, confirmation bias and the backfire effect will become more and more difficult to overcome. You will have more opportunities to pick and choose the kind of information which gets into your head along with the kinds of outlets you trust to give you that information. In addition, advertisers will continue to adapt, not only generating ads based on what they know about you, but creating advertising strategies on the fly based on what has and has not worked on you so far. The media of the future may be delivered based not only on your preferences, but on how you vote, where you grew up, your mood, the time of day or year – every element of you which can be quantified. In a world where everything comes to you on demand, your beliefs may never be challenged.

It's Consumer Spending, Stupid - NYTimes.com - 0 views

  • using business profits to increase productivity and output — doesn’t actually drive economic growth. Consumer debt and government spending do. Private investment isn’t even necessary to promote growth.
  • Economists will tell you that private business investment causes growth because it pays for the new plant or equipment that creates jobs, improves labor productivity and increases workers’ incomes. As a result, you’ll hear politicians insisting that more incentives for private investors — lower taxes on corporate profits — will lead to faster and better-balanced growth.
  • But history shows that this is wrong.
  • ...7 more annotations...
  • President George W. Bush’s tax cuts had similar effects between 2001 and 2007: real growth in the absence of new investment.
  • over the course of the last century, net business investment atrophied while G.D.P. per capita increased spectacularly. And the source of that growth? Increased consumer spending, coupled with and amplified by government outlays.
  • Between 1900 and 2000, real gross domestic product per capita (the output of goods and services per person) grew more than 600 percent. Meanwhile, net business investment declined 70 percent as a share of G.D.P. What’s more, in 1900 almost all investment came from the private sector — from companies, not from government — whereas in 2000, most investment was either from government spending (out of tax revenues) or “residential investment,” which means consumer spending on housing, rather than business expenditure on plants, equipment and labor.
  • According to the Organization for Economic Cooperation and Development, retained corporate earnings that remain uninvested are now close to 8 percent of G.D.P., a staggering sum in view of the unemployment crisis we face.
  • So corporate profits do not drive economic growth — they’re just restless sums of surplus capital, ready to flood speculative markets at home and abroad. In the 1920s, they inflated the stock market bubble, and then caused the Great Crash. Since the Reagan revolution, these superfluous profits have fed corporate mergers and takeovers, driven the dot-com craze, financed the “shadow banking” system of hedge funds and securitized investment vehicles, fueled monetary meltdowns in every hemisphere and inflated the housing bubble.
  • we doubt the moral worth of consumer culture. Like the abstemious ant who scolds the feckless grasshopper as winter approaches, we think that saving is the right thing to do. Even as we shop with abandon, we feel that if only we could contain our unruly desires, we’d be committing ourselves to a better future. But we’re wrong.
  • Consumer spending is not only the key to economic recovery in the short term; it’s also necessary for balanced growth in the long term. If our goal is to repair our damaged economy, we should bank on consumer culture — and that entails a redistribution of income away from profits toward wages, enabled by tax policy and enforced by government spending.

How to Raise a University's Profile: Pricing and Packaging - NYTimes.com - 0 views

  • I talked to a half-dozen of Hugh Moren’s fellow students. A highly indebted senior who was terrified of the weak job market described George Washington, where he had invested considerable time getting and doing internships, as “the world’s most expensive trade school.” Another mentioned the abundance of rich students whose parents were giving them a fancy-sounding diploma the way they might a new car. There are serious students here, he acknowledged, but: “You can go to G.W. and essentially buy a degree.”
  • A recent study from the Organization for Economic Cooperation and Development found that, on average, American college graduates score well below college graduates from most other industrialized countries in mathematics. In literacy (“understanding, evaluating, using and engaging with written text”), scores are just average. This comes on the heels of Richard Arum and Josipa Roksa’s “Academically Adrift,” a study that found “limited or no learning” among many college students.Instead of focusing on undergraduate learning, nu
  • colleges have been engaged in the kind of building spree I saw at George Washington. Recreation centers with world-class workout facilities and lazy rivers rise out of construction pits even as students and parents are handed staggeringly large tuition bills. Colleges compete to hire famous professors even as undergraduates wander through academic programs that often lack rigor or coherence. Campuses vie to become the next Harvard — or at least the next George Washington — while ignoring the growing cost and suspect quality of undergraduate education.

  • Mr. Trachtenberg understood the centrality of the university as a physical place. New structures were a visceral sign of progress. They told visitors, donors and civic leaders that the institution was, like beams and scaffolding rising from the earth, ascending. He added new programs, recruited more students, and followed the dictate of constant expansion.
  • the American research university had evolved into a complicated and somewhat peculiar organization. It was built to be all things to all people: to teach undergraduates, produce knowledge, socialize young men and women, train workers for jobs, anchor local economies, even put on weekend sports events. And excellence was defined by similarity to old, elite institutions. Universities were judged by the quality of their scholars, the size of their endowments, the beauty of their buildings and the test scores of their incoming students.
  • John Silber embarked on a huge building campaign while bringing luminaries like Saul Bellow and Elie Wiesel on board to teach and lend their prestige to the B.U. name, creating a bigger, more famous and much more costly institution. He had helped write a game plan for the aspiring college president.
  • GWU is, for all intents and purposes, a for-profit organization. Best example: study abroad. Their top program, a partnering with Sciences Po, costs each student (30 of them, on a program with 'prestige' status?) a full semester's tuition. It costs GW, according to Sciences Po website, €1000. A neat $20,000 profit per student (who is in digging her/himself deeper and deeper in debt.) Moreover, the school takes a $500 admin fee for the study abroad application! With no guarantee that all credits transfer. Students often lose a partial semester, GW profits again. Nor does GW offer help with an antiquated, one-shot/no transfers, tricky registration process. It's tough luck in gay Paris.Just one of many examples. Dorms with extreme mold, off-campus housing impossible for freshmen and sophomores. Required meal plan: Chick-o-Filet etc. Classes with over 300 students (required).This is not Harvard, but costs same.Emotional problems? Counselors too few. Suicides continue and are not appropriately addressed. Caring environment? Extension so and so, please hold.It's an impressive campus, I'm an alum. If you apply, make sure the DC experience is worth the price: good are internships, a few colleges like Elliot School, post-grad.GWU uses undergrad $$ directly for building projects, like the medical center to which students have NO access. (Student health facility is underfunded, outsourced.)Outstanding professors still make a difference. But is that enough?
  • Mr. Trachtenberg, however, understood something crucial about the modern university. It had come to inhabit a market for luxury goods. People don’t buy Gucci bags merely for their beauty and functionality. They buy them because other people will know they can afford the price of purchase. The great virtue of a luxury good, from the manufacturer’s standpoint, isn’t just that people will pay extra money for the feeling associated with a name brand. It’s that the high price is, in and of itself, a crucial part of what people are buying.
  • Mr. Trachtenberg convinced people that George Washington was worth a lot more money by charging a lot more money. Unlike most college presidents, he was surprisingly candid about his strategy. College is like vodka, he liked to explain.
  • The Absolut Rolex plan worked. The number of applicants surged from some 6,000 to 20,000, the average SAT score of students rose by nearly 200 points, and the endowment jumped from $200 million to almost $1 billion.
  • The university became a magnet for the children of new money who didn’t quite have the SATs or family connections required for admission to Stanford or Yale. It also aggressively recruited international students, rich families from Asia and the Middle East who believed, as nearly everyone did, that American universities were the best in the world.
  • U.S. News & World Report now ranks the university at No. 54 nationwide, just outside the “first tier.”
  • The watch and vodka analogies are correct. Personally, I used car analogies when discussing college choices with my kids. We were in the fortunate position of being able to comfortably send our kids to any college in the country and have them leave debt free. Notwithstanding, I told them that they would be going to a state school unless they were able to get into one of about 40 schools that I felt, in whatever arbitrary manner I decided, that was worth the extra cost. They both ended up going to state schools.College is by and large a commodity and you get out of it what you put into it. Both of my kids worked hard in college and were involved in school life. They both left the schools better people and the schools better schools for them being there. They are both now successful adults.I believe too many people look for the prestige of a named school and that is not what college should be primarily about.
  • In 2013, only 14 percent of the university’s 10,000 undergraduates received a grant — a figure on a par with elite schools but far below the national average. The average undergraduate borrower leaves with about $30,800 in debt.
  • When I talk to the best high school students in my state I always stress the benefits of the honors college experience at an affordable public university. For students who won't qualify for a public honors college. the regular pubic university experience is far preferable to the huge debt of places like GW.
  • Carey would do well to look beyond high ticket private universities (which after all are still private enterprises) and what he describes as the Olympian heights of higher education (which for some reason seems also to embitter him) and look at the system overall . The withdrawal of public support was never a policy choice; it was a political choice, "packaged and branded" as some tax cutting palaver all wrapped up in the argument that a free-market should decide how much college should cost and how many seats we need. In such an environment, trustees at private universities are no more solely responsible for turning their degrees into commodities than the administrations of state universities are for raising the number of out-of-state students in order to offset the loss of support from their legislatures. No doubt, we will hear more about market based solutions and technology from Mr. Carey
  • I went to GW back in the 60s. It was affordable and it got me away from home in New York. While I was there, Newsweek famously published a article about the DC Universities - GW, Georgetown, American and Catholic - dubbing them the Pony league, the schools for the children of wealthy middle class New Yorkers who couldn't get into the Ivy League. Nobody really complained. But that wasn't me. I went because I wanted to be where the action was in the 60s, and as we used to say - "GW was literally a stone's throw from the White House. And we could prove it." Back then, the two biggest alumni names were Jackie Kennedy, who's taken some classes there, and J. Edgar Hoover. Now, according to the glossy magazine they send me each month, it's the actress Kerry Washington. There's some sort of progress there, but I'm a GW alum and not properly trained to understand it.
  • This explains a lot of the modern, emerging mentality. It encompasses the culture of enforced grade inflation, cheating and anti-intellectualism in much of higher education. It is consistent with our culture of misleading statistics and information, cronyism and fake quality, the "best and the brightest" being only schemers and glad handers. The wisdom and creativity engendered by an honest, rigorous academic education are replaced by the disingenuous quick fix, the winner-take-all mentality that neglects the common good.
  • I attended nearby Georgetown University and graduated in 1985. Relative to state schools and elite schools, it was expensive then. I took out loans. I had Pell grants. I had work-study and GSL. I paid my debt of $15,000 off in ten years. Would I have done it differently? Yes: I would have continued on to graduate school and not worried about paying off those big loans right after college. My career work out and I am grateful for the education I received and paid for. But I would not recommend to my nieces and nephews debts north of $100,000 for a BA in liberal arts. Go community. Then go state. Then punch your ticket to Harvard, Yale or Stanford — if you are good enough.
  • American universities appear to have more and more drifted away from educating individuals and citizens to becoming high priced trade schools and purveyors of occupational licenses. Lost in the process is the concept of expanding a student's ability to appreciate broadly and deeply, as well as the belief that a republican democracy needs an educated citizenry, not a trained citizenry, to function well.Both the Heisman Trophy winner and the producer of a successful tech I.P.O. likely have much in common, a college education whose rewards are limited to the financial. I don't know if I find this more sad on the individual level or more worrisome for the future of America.
  • This is now a consumer world for everything, including institutions once thought to float above the Shakespearean briars of the work-a-day world such as higher education, law and medicine. Students get this. Parents get this. Everything is negotiable: financial aid, a spot in the nicest dorm, tix to the big game. But through all this, there are faculty - lots of 'em - who work away from the fluff to link the ambitions of the students with the reality and rigor of the 21st century. The job of the student is to get beyond the visible hype of the surroundings and find those faculty members. They will make sure your investment is worth it
  • My experience in managing or working with GW alumni in their 20's or 30's has not been good. Virtually all have been mentally lazy and/or had a stunning sense of entitlement. Basically they've been all talk and no results. That's been quite a contrast to the graduates from VA/MD state universities.
  • More and more, I notice what my debt-financed contributions to the revenue streams of my vendors earn them, not me. My banks earned enough to pay ridiculous bonuses to employees for reckless risk-taking. My satellite tv operator earned enough to overpay ESPN for sports programming that I never watch--and that, in turn, overpays these idiotic pro athletes and college sports administrators. My health insurer earned enough to defeat one-payor insurance; to enable the opaque, inefficient billing practices of hospitals and other providers; and to feed the behemoth pharmaceutical industry. My church earned enough to buy the silence of sex abuse victims and oppose progressive political candidates. And my govt earned enough to continue ag subsidies, inefficient defense spending, and obsolete transportation and energy policies.
  • as the parent of GWU freshman I am grateful for every opportunity afforded her. She has a generous merit scholarship, is in the honors program with some small classes, and has access to internships that can be done while at school. GWU also gave her AP credits to advance her to sophomore status. Had she attended the state flagship school (where she was accepted into that exclusive honors program) she would have a great education but little else. It's not possible to do foreign affairs related internship far from D.C. or Manhattan. She went to a very competitive high school where for the one or two ivy league schools in which she was interested, she didn't have the same level of connections or wealth as many of her peers. Whether because of the Common Application or other factors, getting into a good school with financial help is difficult for a middle class student like my daughter who had a 4.0 GPA and 2300 on the SAT. She also worked after school.The bottom line - GWU offered more money than perceived "higher tier" universities, and brought tuition to almost that of our state school system. And by the way, I think she is also getting a very good education.
  • This article reinforces something I have learned during my daughter's college application process. Most students choose a school based on emotion (reputation) and not value. This luxury good analogy holds up.
  • The entire education problem can be solved by MOOCs lots and lots of them plus a few closely monitored tests and personal interviews with people. Of course many many people make MONEY off of our entirely inefficient way of "educating" -- are we even really doing that -- getting a degree does NOT mean one is actually educated
  • As a first-generation college graduate I entered GW ambitious but left saddled with debt, and crestfallen at the hard-hitting realization that my four undergraduate years were an aberration from what life is actually like post-college: not as simple as getting an [unpaid] internship with a fancy titled institution, as most Colonials do. I knew how to get in to college, but what do you do after the recess of life ends?I learned more about networking, resume plumping (designated responses to constituents...errr....replied to emails), and elevator pitches than actual theory, economic principles, strong writing skills, critical thinking, analysis, and philosophy. While relatively easy to get a job after graduating (for many with a GW degree this is sadly not the case) sustaining one and excelling in it is much harder. It's never enough just to be able to open a new door, you also need to be prepared to navigate your way through that next opportunity.
  • this is a very telling article. Aimless and directionless high school graduates are matched only by aimless and directionless institutes of higher learning. Each child and each parent should start with a goal - before handing over their hard earned tuition dollars, and/or leaving a trail of broken debt in the aftermath of a substandard, unfocused education.
  • it is no longer the most expensive university in America. It is the 46th.Others have been implementing the Absolut Rolex Plan. John Sexton turned New York University into a global higher-education player by selling the dream of downtown living to students raised on “Sex and the City.” Northeastern followed Boston University up the ladder. Under Steven B. Sample, the University of Southern California became a U.S. News top-25 university. Washington University in St. Louis did the same.
  • I currently attend GW, and I have to say, this article completely misrepresents the situation. I have yet to meet a single person who is paying the full $60k tuition - I myself am paying $30k, because the school gave me $30k in grants. As for the quality of education, Foreign Policy rated GW the #8 best school in the world for undergraduate education in international affairs, Princeton Review ranks it as one of the best schools for political science, and U.S. News ranks the law school #20. The author also ignores the role that an expanding research profile plays in growing a university's prestige and educational power.
  • And in hundreds of regional universities and community colleges, presidents and deans and department chairmen have watched this spectacle of ascension and said to themselves, “That could be me.” Agricultural schools and technical institutes are lobbying state legislatures for tuition increases and Ph.D. programs, fitness centers and arenas for sport. Presidents and boards are drawing up plans to raise tuition, recruit “better” students and add academic programs. They all want to go in one direction — up! — and they are all moving with a single vision of what they want to be.
  • this is the same playbook used by hospitals the past 30 years or so. It is how Hackensack Hospital became Hackensack Medical Center and McComb Hospital became Southwest Mississippi Regional Medical Center. No wonder the results have been the same in healthcare and higher education; both have priced themselves out of reach for average Americans.
  • a world where a college is rated not by the quality of its output, but instaed, by the quality of its inputs. A world where there is practically no work to be done by the administration because the college's reputation is made before the first class even begins! This is isanity! But this is the swill that the mammoth college marketing departments nationwide have shoved down America's throat. Colleges are ranked not by the quality of their graduates, but rather, by the test scores of their incoming students!
  • The Pew Foundation has been doing surveys on what students learn, how much homework they do, how much time they spend with professors etc. All good stuff to know before a student chooses a school. It is called the National Survey of Student Engagement (NSSE - called Nessy). It turns out that the higher ranked schools do NOT allow their information to be released to the public. It is SECRET.Why do you think that is?
  • The article blames "the standard university organizational model left teaching responsibilities to autonomous academic departments and individual faculty members, each of which taught and tested in its own way." This is the view of someone who has never taught at a university, nor thought much about how education there actually happens. Once undergraduates get beyond the general requirements, their educations _have_ to depend on "autonomous departments" because it's only those departments know what the requirements for given degree can be, and can grant the necessary accreditation of a given student. The idea that some administrator could know what's necessary for degrees in everything from engineering to fiction writing is nonsense, except that's what the people who only know the theory of education (but not its practice) actually seem to think. In the classroom itself, you have tremendously talented people, who nevertheless have their own particular strengths and approaches. Don't you think it's a good idea to let them do what they do best rather than trying to make everyone teach the same way? Don't you think supervision of young teachers by older colleagues, who actually know their field and its pedagogy, rather than some administrator, who knows nothing of the subject, is a good idea?
  • it makes me very sad to see how expensive some public schools have become. Used to be you could work your way through a public school without loans, but not any more. Like you, I had the advantage of a largely-scholarship paid undergraduate education at a top private college. However, I was also offered a virtually free spot in my state university's (then new) honors college
  • My daughter attended a good community college for a couple of classes during her senior year of high school and I could immediately see how such places are laboratories for failure. They seem like high schools in atmosphere and appearance. Students rush in by car and rush out again when the class is over.The four year residency college creates a completely different feel. On arrival, you get the sense that you are engaging in something important, something apart and one that will require your full attention. I don't say this is for everyone or that the model is not flawed in some ways (students actually only spend 2 1/2 yrs. on campus to get the four yr. degree). College is supposed to be a 60 hour per week job. Anything less than that and the student is seeking himself or herself
  • This. Is. STUNNING. I have always wondered, especially as my kids have approached college age, why American colleges have felt justified in raising tuition at a rate that has well exceeded inflation, year after year after year. (Nobody needs a dorm with luxury suites and a lazy river pool at college!) And as it turns out, they did it to become luxury brands. Just that simple. Incredible.I don't even blame this guy at GWU for doing what he did. He wasn't made responsible for all of American higher ed. But I do think we all need to realize what happened, and why. This is front page stuff.
  • I agree with you, but, unfortunately, given the choice between low tuition, primitive dorms, and no athletic center VS expensive & luxurious, the customers (and their parents) are choosing the latter. As long as this is the case, there is little incentive to provide bare-bones and cheap education.
  • Wesleyan University in CT is one school that is moving down the rankings. Syracuse University is another. Reed College is a third. Why? Because these schools try hard to stay out of the marketing game. (With its new president, Syracuse has jumped back into the game.) Bryn Mawr College, outside Philadelphia hasn't fared well over the past few decades in the rankings, which is true of practically every women's college. Wellesley is by far the highest ranked women's college, but even there the acceptance rate is significantly higher than one finds at comparable coed liberal arts colleges like Amherst & Williams. University of Chicago is another fascinating case for Mr. Carey to study (I'm sure he does in his forthcoming book, which I look forward to reading). Although it has always enjoyed an illustrious academic reputation, until recently Chicago's undergraduate reputation paled in comparison to peer institutions on the two coasts. A few years ago, Chicago changed its game plan to more closely resemble Harvard and Stanford in undergraduate amenities, and lo and behold, its rankings shot up. It was a very cynical move on the president's part to reassemble the football team, but it was a shrewd move because athletics draw more money than academics ever can (except at engineering schools like Cal Tech & MIT), and more money draws richer students from fancier secondary schools with higher test scores, which lead to higher rankings - and the beat goes on.
  • College INDUSTRY is out of control. Sorry, NYU, GW, BU are not worth the price. Are state schools any better? We have the University of Michigan, which is really not a state school, but a university that gives a discount to people who live in Michigan. Why? When you have an undergraduate body 40+% out-of-state that pays tuition of over $50K/year, you tell me?Perhaps the solution is two years of community college followed by two at places like U of M or Michigan State - get the same diploma at the end for much less and beat the system.
  • In one recent yr., the majority of undergrad professors at Harvard, according to Boston.com, where adjuncts. That means low pay, no benefits, no office, temp workers. Harvard.Easily available student loans fueled this arms race of amenities and frills that in which colleges now engage. They moved the cost of education onto the backs of people, kids, who don't understand what they are doing.Students in colleges these days are customers and the customers must be able to get through. If it requires dumbing things down, so be it. On top of tuition, G.W. U. is known by its students as the land of added fees on top of added fees. The joke around campus was that they would soon be installing pay toilets in the student union. No one was laughing.
  • You could written the same story about my alma mater, American University. The place reeked of ambition and upward mobility decades ago and still does. Whoever's running it now must look at its measly half-billion-dollar endowment and compare it to GWU's $1.5 billion and seethe with envy, while GWU's president sets his sights on an Ivy League-size endowment. And both get back to their real jobs: 24/7 fundraising,Which is what university presidents are all about these days. Money - including million-dollar salaries for themselves (GWU's president made more than Harvard's in 2011) - pride, cachet, power, a mansion, first-class all the way. They should just be honest about it and change their university's motto to Ostende mihi pecuniam! (please excuse my questionable Latin)Whether the students are actually learning anything is up to them, I guess - if they do, it's thanks to the professors, adjuncts and the administrative staff, who do the actual work of educating and keep the school running.
  • When I was in HS (70s), many of my richer friends went to GW and I was then of the impression that GW was a 'good' school. As I age, I have come to realize that this place is just another façade to the emptiness that has become America. All too often are we faced with a dilemma: damned if we do, damned if we don't. Yep, 'education' has become a trap for all too many of our citizen.
  • I transferred to GWU from a state school. I am forever grateful that I did. I wanted to get a good rigorous education and go to one of the best International Affairs schools in the world. Even though the state school I went to was dirt-cheap, the education and the faculty was awful. I transferred to GW and was amazed at the professors at that university. An ambassador or a prominent IA scholar taught every class. GW is an expensive school, but that is the free market. If you want a good education you need to be willing to pay for it or join the military. I did the latter and my school was completely free with no debt and I received an amazing education. If young people aren't willing to make some sort of sacrifice to get ahead or just expect everything to be given to then our country is in a sad state.We need to stop blaming universities like GWU that strive to attract better students, better professors, and better infrastructure. They are doing what is expected in America, to better oneself.
  • "Whether the students are actually learning anything is up to them, I guess." How could it possibly be otherwise??? I am glad that you are willing to give credit to teachers and administrators, but it is not they who "do the actual work of educating." From this fallacy comes its corollary, that we should blame teachers first for "under-performing schools". This long-running show of scapegoating may suit the wallets and vanity of American parents, but it is utterly senseless. When, if ever, American culture stops reeking of arrogance, greed and anti-intellectualism, things may improve, and we may resume the habit of bothering to learn. Until then, nothing doing.
  • Universities sell knowledge and grade students on how much they have learned. Fundamentally, there is conflict of interest in thsi setup. Moreover, students who are poorly educated, even if they know this, will not criticize their school, because doing so would make it harder for them to have a career. As such, many problems with higher education remain unexposed to the public.
  • I've lectured and taught in at least five different countries in three continents and the shortest perusal of what goes on abroad would totally undermine most of these speculations. For one thing American universities are unique in their dedication to a broad based liberal arts type education. In France, Italy or Germany, for example, you select a major like mathematics or physics and then in your four years you will not take even one course in another subject. The amount of work that you do that is critically evaluated by an instructor is a tiny fraction of what is done in an American University. While half educated critics based on profoundly incomplete research write criticism like this Universities in Germany Italy, the Netherlands, South Korea and Japan as well as France have appointed committees and made studies to explain why the American system of higher education so drastically outperforms their own system. Elsewhere students do get a rather nice dose of general education but it ends in secondary school and it has the narrowness and formulaic quality that we would just normally associate with that. The character who wrote this article probably never set foot on a "campus" of the University of Paris or Rome
  • The university is part of a complex economic system and it is responding to the demands of that system. For example, students and parents choose universities that have beautiful campuses and buildings. So universities build beautiful campuses. State support of universities has greatly declined, and this decline in funding is the greatest cause of increased tuition. Therefore universities must compete for dollars and must build to attract students and parents. Also, universities are not ranked based on how they educate students -- that's difficult to measure so it is not measured. Instead universities are ranked on research publications. So while universities certainly put much effort into teaching, research has to have a priority in order for the university to survive. Also universities do not force students and parents to attend high price institutions. Reasonably priced state institutions and community colleges are available to every student. Community colleges have an advantage because they are funded by property taxes. Finally learning requires good teaching, but it also requires students that come to the university funded, prepared, and engaged. This often does not happen. Conclusion- universities have to participate in profile raising actions in order to survive. The day that funding is provided for college, ranking is based on education, and students choose campuses with simple buildings, then things will change at the university.
  • This is the inevitable result of privatizing higher education. In the not-so-distant past, we paid for great state universities through our taxes, not tuition. Then, the states shifted funding to prisons and the Federal government radically cut research support and the GI bill. Instead, today we expect universities to support themselves through tuition, and to the extent that we offered students support, it is through non-dischargeable loans. To make matters worse, the interest rates on those loans are far above the government's cost of funds -- so in effect the loans are an excise tax on education (most of which is used to support a handful of for-profit institutions that account for the most student defaults). This "consumer sovereignty" privatized model of funding education works no better than privatizing California's electrical system did in the era of Enron, or our privatized funding of medical service, or our increasingly privatized prison system: it drives up costs at the same time that it replace quality with marketing.
  • There are data in some instances on student learning, but the deeper problem, as I suspect the author already knows, is that there is nothing like a consensus on how to measure that learning, or even on when is the proper end point to emphasize (a lot of what I teach -- I know this from what students have told me -- tends to come into sharp focus years after graduation).
  • Michael (Baltimore) has hit the nail on the head. Universities are increasingly corporatized institutions in the credentialing business. Knowledge, for those few who care about it (often not those paying for the credentials) is available freely because there's no profit in it. Like many corporate entities, it is increasingly run by increasingly highly paid administrators, not faculty.
  • GWU has not defined itself in any unique way, it has merely embraced the bland, but very expensive, accoutrements of American private education: luxury dorms, food courts, spa-like gyms, endless extracurricular activities, etc. But the real culprit for this bloat that students have to bear financially is the college ranking system by US News, Princeton Review, etc. An ultimately meaningless exercise in competition that has nevertheless pushed colleges and universities to be more like one another. A sad state of affairs, and an extremely expensive one for students
  • It is long past time to realize the failure of the Reagonomics-neoliberal private profits over public good program. In education, we need to return to public institutions publicly funded. Just as we need to recognize that Medicare, Social Security, the post office, public utilities, fire departments, interstate highway system, Veterans Administration hospitals and the GI bill are models to be improved and expanded, not destroyed.
  • George Washington is actually not a Rolex watch, it is a counterfeit Rolex. The real Rolexes of higher education -- places like Hopkins, Georgetown, Duke, the Ivies etc. -- have real endowments and real financial aid. No middle class kid is required to borrow $100,000 to get a degree from those schools, because they offer generous need-based financial aid in the form of grants, not loans. The tuition at the real Rolexes is really a sticker price that only the wealthy pay -- everybody else on a sliding scale. For middle class kids who are fortunate enough to get in, Penn actually ends up costing considerably less than a state university.The fake Rolexes -- BU, NYU, Drexel in Philadelphia -- don't have the sliding scale. They bury middle class students in debt.And really, though it is foolish to borrow $100,000 or $120,000 for an undergraduate degree, I don't find the transaction morally wrong. What is morally wrong is our federal government making that loan non-dischargeable in bankruptcy, so many if these kids will be having their wages garnished for the REST OF THEIR LIVES.There is a very simple solution to this, by the way. Cap the amount of non-dischargeable student loan debt at, say, $50,000
  • The slant of this article is critical of the growth of research universities. Couldn't disagree more. Modern research universities create are incredibly engines of economic opportunity not only for the students (who pay the bills) but also for the community via the creation of blue and white collar jobs. Large research university employ tens of thousands of locals from custodial and food service workers right up to high level administrators and specialist in finance, computer services, buildings and facilities management, etc. Johns Hopkins University and the University of Maryland system employ more people than any other industry in Maryland -- including the government. Research universities typically have hospitals providing cutting-edge medical care to the community. Local business (from cafes to property rental companies) benefit from a built-in, long-term client base as well as an educated workforce. And of course they are the foundry of new knowledge which is critical for the future growth of our country.Check out the work of famed economist Dr. Julia Lane on modeling the economic value of the research university. In a nutshell, there are few better investments America can make in herself than research universities. We are the envy of the world in that regard -- and with good reason. How many *industries* (let alone jobs) have Stanford University alone catalyzed?
  • What universities have the monopoly on is the credential. Anyone can learn, from books, from free lectures on the internet, from this newspaper, etc. But only universities can endow you with the cherished degree. For some reason, people are will to pay more for one of these pieces of paper with a certain name on it -- Ivy League, Stanford, even GW -- than another -- Generic State U -- though there is no evidence one is actually worth more in the marketplace of reality than the other. But, by the laws of economics, these places are actually underpriced: after all, something like 20 times more people are trying to buy a Harvard education than are allowed to purchase one. Usually that means you raise your price.
  • Overalll a good article, except for - "This comes on the heels of Richard Arum and Josipa Roksa’s “Academically Adrift,” a study that found “limited or no learning” among many college students." The measure of learning you report was a general thinking skills exam. That's not a good measure of college gains. Most psychologists and cognitive scientists worth their salt would tell you that improvement in critical thinking skills is going to be limited to specific areas. In other words, learning critical thinking skills in math will make little change in critical thinking about political science or biology. Thus we should not expect huge improvements in general critical thinking skills, but rather improvements in a student's major and other areas of focus, such as a minor. Although who has time for a minor when it is universally acknowledged that the purpose of a university is to please and profit an employer or, if one is lucky, an investor. Finally, improved critical thinking skills are not the end all and be all of a college education even given this profit centered perspective. Learning and mastering the cumulative knowledge of past generations is arguably the most important thing to be gained, and most universities still tend to excel at that even with the increasing mandate to run education like a business and cultivate and cull the college "consumer".
  • As for community colleges, there was an article in the Times several years ago that said it much better than I could have said it myself: community colleges are places where dreams are put on hold. Without making the full commitment to study, without leaving the home environment, many, if not most, community college students are caught betwixt and between, trying to balance work responsibilities, caring for a young child or baby and attending classes. For males, the classic "end of the road" in community college is to get a car, a job and a girlfriend, one who is not in college, and that is the end of the dream. Some can make it, but most cannot.
  • as a scientist I disagree with the claim that undergrad tuition subsidizes basic research. Nearly all lab equipment and research personnel (grad students, technicians, anyone with the title "research scientist" or similar) on campus is paid for through federal grants. Professors often spend all their time outside teaching and administration writing grant proposals, as the limited federal grant funds mean ~%85 of proposals must be rejected. What is more, out of each successful grant the university levies a "tax", called "overhead", of 30-40%, nominally to pay for basic operations (utilities, office space, administrators). So in fact one might say research helps fund the university rather than the other way around. Flag
  • It's certainly overrated as a research and graduate level university. Whether it is good for getting an undergraduate education is unclear, but a big part of the appeal is getting to live in D.C..while attending college instead of living in some small college town in the corn fields.

The Economist explains: How teenage brains are different | The Economist - 0 views

  • is there such a thing as a “teenage brain”, and does it help to explain the high rates of recklessness among teenagers?
  • the brain blooms with neural connections until a child reaches the age of 11 or 12, and then it selectively prunes away the underused ones, or “grey matter”, throughout adolescence. As the brain grows more streamlined, it becomes better at processing information.
  • The remaining connections are then made more efficient by a process called myelination, which essentially insulates neuronal axons with a sheath of fatty cell material, or “white matter”. The process of replacing grey matter with white matter does not reach the prefrontal cortex until people are in their early 20s. Studies show a relationship between increased myelination and an improved ability to make decisions and control impulses.

  • But although it is always tempting to use hard science to explain otherwise perplexing behaviour, neuroimaging research is still in its infancy
  • There is much about the brain that no one understands yet, and there is rarely a clear relationship between a particular brain region and a discrete function, so any links between brain structure and behaviour remain speculative. Indeed, while researchers often take care to show that the relationship between how a brain looks and how someone behaves is correlative, often this link is misinterpreted as a sign of causation
  • Scientists also point out that brain science cannot be understood in a vacuum. All behaviour is a function of many influences, including parenting, socioeconomic status, nutrition, culture and so on

Which Type of Exercise Is Best for the Brain? - The New York Times - 1 views

  • Some forms of exercise may be much more effective than others at bulking up the brain, according to a remarkable new study in rats. For the first time, scientists compared head-to-head the neurological impacts of different types of exercise: running, weight training and high-intensity interval training. The surprising results suggest that going hard may not be the best option for long-term brain health.
  • exercise changes the structure and function of the brain. Studies in animals and people have shown that physical activity generally increases brain volume and can reduce the number and size of age-related holes in the brain’s white and gray matter.
  • Exercise also, and perhaps most resonantly, augments adult neurogenesis, which is the creation of new brain cells in an already mature brain. In studies with animals, exercise, in the form of running wheels or treadmills, has been found to double or even triple the number of new neurons that appear afterward in the animals’ hippocampus, a key area of the brain for learning and memory, compared to the brains of animals that remain sedentary. Scientists believe that exercise has similar impacts on the human hippocampus.
  • ...7 more annotations...
  • These past studies of exercise and neurogenesis understandably have focused on distance running. Lab rodents know how to run. But whether other forms of exercise likewise prompt increases in neurogenesis has been unknown and is an issue of increasing interest
  • new study, which was published this month in the Journal of Physiology, researchers at the University of Jyvaskyla in Finland and other institutions gathered a large group of adult male rats. The researchers injected the rats with a substance that marks new brain cells and then set groups of them to an array of different workouts, with one group remaining sedentary to serve as controls.
  • They found very different levels of neurogenesis, depending on how each animal had exercised. Those rats that had jogged on wheels showed robust levels of neurogenesis. Their hippocampal tissue teemed with new neurons, far more than in the brains of the sedentary animals. The greater the distance that a runner had covered during the experiment, the more new cells its brain now contained. There were far fewer new neurons in the brains of the animals that had completed high-intensity interval training. They showed somewhat higher amounts than in the sedentary animals but far less than in the distance runners. And the weight-training rats, although they were much stronger at the end of the experiment than they had been at the start, showed no discernible augmentation of neurogenesis. Their hippocampal tissue looked just like that of the animals that had not exercised at all.
  • “sustained aerobic exercise might be most beneficial for brain health also in humans.”
  • Just why distance running was so much more potent at promoting neurogenesis than the other workouts is not clear, although Dr. Nokia and her colleagues speculate that distance running stimulates the release of a particular substance in the brain known as brain-derived neurotrophic factor that is known to regulate neurogenesis. The more miles an animal runs, the more B.D.N.F. it produces. Weight training, on the other hand, while extremely beneficial for muscular health, has previously been shown to have little effect on the body’s levels of B.D.N.F.
  • As for high-intensity interval training, its potential brain benefits may be undercut by its very intensity, Dr. Nokia said. It is, by intent, much more physiologically draining and stressful than moderate running, and “stress tends to decrease adult hippocampal neurogenesis,” she said.
  • These results do not mean, however, that only running and similar moderate endurance workouts strengthen the brain, Dr. Nokia said. Those activities do seem to prompt the most neurogenesis in the hippocampus. But weight training and high-intensity intervals probably lead to different types of changes elsewhere in the brain. They might, for instance, encourage the creation of additional blood vessels or new connections between brain cells or between different parts of the brain.

BBC - Future - The surprising downsides of being clever - 0 views

  • If ignorance is bliss, does a high IQ equal misery? Popular opinion would have it so. We tend to think of geniuses as being plagued by existential angst, frustration, and loneliness. Think of Virginia Woolf, Alan Turing, or Lisa Simpson – lone stars, isolated even as they burn their brightest. As Ernest Hemingway wrote: “Happiness in intelligent people is the rarest thing I know.”
  • Combing California’s schools for the creme de la creme, he selected 1,500 pupils with an IQ of 140 or more – 80 of whom had IQs above 170. Together, they became known as the “Termites”, and the highs and lows of their lives are still being studied to this day.
  • Termites’ average salary was twice that of the average white-collar job. But not all the group met Terman’s expectations – there were many who pursued more “humble” professions such as police officers, seafarers, and typists. For this reason, Terman concluded that “intellect and achievement are far from perfectly correlated”. Nor did their smarts endow personal happiness. Over the course of their lives, levels of divorce, alcoholism and suicide were about the same as the national average.
  • ...16 more annotations...
  • One possibility is that knowledge of your talents becomes something of a ball and chain. Indeed, during the 1990s, the surviving Termites were asked to look back at the events in their 80-year lifespan. Rather than basking in their successes, many reported that they had been plagued by the sense that they had somehow failed to live up to their youthful expectations.
  • The most notable, and sad, case concerns the maths prodigy Sufiah Yusof. Enrolled at Oxford University aged 12, she dropped out of her course before taking her finals and started waitressing. She later worked as a call girl, entertaining clients with her ability to recite equations during sexual acts.
  • Another common complaint, often heard in student bars and internet forums, is that smarter people somehow have a clearer vision of the world’s failings. Whereas the rest of us are blinkered from existential angst, smarter people lay awake agonising over the human condition or other people’s folly.
  • MacEwan University in Canada found that those with the higher IQ did indeed feel more anxiety throughout the day. Interestingly, most worries were mundane, day-to-day concerns, though; the high-IQ students were far more likely to be replaying an awkward conversation, than asking the “big questions”. “It’s not that their worries were more profound, but they are just worrying more often about more things,” says Penney. “If something negative happened, they thought about it more.”
  • seemed to correlate with verbal intelligence – the kind tested by word games in IQ tests, compared to prowess at spatial puzzles (which, in fact, seemed to reduce the risk of anxiety). He speculates that greater eloquence might also make you more likely to verbalise anxieties and ruminate over them. It’s not necessarily a disadvantage, though. “Maybe they were problem-solving a bit more than most people,” he says – which might help them to learn from their mistakes.
  • The harsh truth, however, is that greater intelligence does not equate to wiser decisions; in fact, in some cases it might make your choices a little more foolish.
  • we need to turn our minds to an age-old concept: “wisdom”. His approach is more scientific that it might at first sound. “The concept of wisdom has an ethereal quality to it,” he admits. “But if you look at the lay definition of wisdom, many people would agree it’s the idea of someone who can make good unbiased judgement.”
  • “my-side bias” – our tendency to be highly selective in the information we collect so that it reinforces our previous attitudes. The more enlightened approach would be to leave your assumptions at the door as you build your argument – but Stanovich found that smarter people are almost no more likely to do so than people with distinctly average IQs.
  • People who ace standard cognitive tests are in fact slightly more likely to have a “bias blind spot”. That is, they are less able to see their own flaws, even when though they are quite capable of criticising the foibles of others. And they have a greater tendency to fall for the “gambler’s fallacy”
  • A tendency to rely on gut instincts rather than rational thought might also explain why a surprisingly high number of Mensa members believe in the paranormal; or why someone with an IQ of 140 is about twice as likely to max out their credit card.
  • “The people pushing the anti-vaccination meme on parents and spreading misinformation on websites are generally of more than average intelligence and education.” Clearly, clever people can be dangerously, and foolishly, misguided.
  • spent the last decade building tests for rationality, and he has found that fair, unbiased decision-making is largely independent of IQ.
  • Crucially, Grossmann found that IQ was not related to any of these measures, and certainly didn’t predict greater wisdom. “People who are very sharp may generate, very quickly, arguments [for] why their claims are the correct ones – but may do it in a very biased fashion.”
  • employers may well begin to start testing these abilities in place of IQ; Google has already announced that it plans to screen candidates for qualities like intellectual humility, rather than sheer cognitive prowess.
  • He points out that we often find it easier to leave our biases behind when we consider other people, rather than ourselves. Along these lines, he has found that simply talking through your problems in the third person (“he” or “she”, rather than “I”) helps create the necessary emotional distance, reducing your prejudices and leading to wiser arguments.
  • If you’ve been able to rest on the laurels of your intelligence all your life, it could be very hard to accept that it has been blinding your judgement. As Socrates had it: the wisest person really may be the one who can admit he knows nothing.

Physicists in Europe Find Tantalizing Hints of a Mysterious New Particle - The New York... - 1 views

  • seen traces of what could be a new fundamental particle of nature.
  • One possibility, out of a gaggle of wild and not-so-wild ideas springing to life as the day went on, is that the particle — assuming it is real — is a heavier version of the Higgs boson, a particle that explains why other particles have mass. Another is that it is a graviton, the supposed quantum carrier of gravity, whose discovery could imply the existence of extra dimensions of space-time.
  • At the end of a long chain of “ifs” could be a revolution, the first clues to a theory of nature that goes beyond the so-called Standard Model, which has ruled physics for the last quarter-century.

  • noting that the history of particle physics is rife with statistical flukes and anomalies that disappeared when more data was compiled
  • A coincidence is the most probable explanation for the surprising bumps in data from the collider, physicists from the experiments cautioned
  • Physicists could not help wondering if history was about to repeat itself. It was four years ago this week that the same two teams’ detection of matching bumps in Large Hadron Collider data set the clock ticking for the discovery of the Higgs boson six months later.
  • If the particle is real, Dr. Lykken said, physicists should know by this summer, when they will have 10 times as much data to present to scientists from around the world who will convene in Chicago
  • The Higgs boson was the last missing piece of the Standard Model, which explains all we know about subatomic particles and forces. But there are questions this model does not answer, such as what happens at the bottom of a black hole, the identity of the dark matter and dark energy that rule the cosmos, or why the universe is matter and not antimatter.
  • CERN physicists have been running their collider at nearly twice the energy with which they discovered the Higgs, firing twin beams of protons with 6.5 trillion electron volts of energy at each other in search of new particles to help point them to deeper laws.The main news since then has been mainly that there is no news yet, only tantalizing hints, bumps in the data, that might be new particles and signposts of new theories, or statistical demons.
  • Or it could be a more massive particle that has decayed in steps down to a pair of photons. Nobody knows. No model predicted this, which is how some scientists like it.
  • “The more nonstandard the better,” said Joe Lykken, the director of research at the Fermi National Accelerator Laboratory and a member of one of the CERN teams. “It will give people a lot to think about. We get paid to speculate.”
  • When physicists announced in 2012 that they had indeed discovered the Higgs boson, it was not the end of physics. It was not even, to paraphrase Winston Churchill, the beginning of the end.It might, they hoped, be the end of the beginning.
  • Such a discovery would augur a fruitful future for cosmological wanderings and for the CERN collider, which will be running for the next 20 years.

Opinion | Knowledge, Ignorance and Climate Change - The New York Times - 1 views

  • the value of being aware of our ignorance has been a recurring theme in Western thought: René Descartes said it’s necessary to doubt all things to build a solid foundation for science; and Ludwig Wittgenstein, reflecting on the limits of language, said that “the difficulty in philosophy is to say no more than we know.”
  • Sometimes, when it appears that someone is expressing doubt, what he is really doing is recommending a course of action. For example, if I tell you that I don’t know whether there is milk in the fridge, I’m not exhibiting philosophical wisdom — I’m simply recommending that you check the fridge before you go shopping.
  • According to NASA, at least 97 percent of actively publishing climate scientists think that “climate-warming trends over the past century are extremely likely caused by human activities.”
  • ...14 more annotations...
  • As a philosopher, I have nothing to add to the scientific evidence of global warming, but I can tell you how it’s possible to get ourselves to sincerely doubt things, despite abundant evidence to the contrary
  • scenarios suggest that it’s possible to feel as though you don’t know something even when possessing enormous evidence in its favor. Philosophers call scenarios like these “skeptical pressure” cases
  • In general, a skeptical pressure case is a thought experiment in which the protagonist has good evidence for something that he or she believes, but the reader is reminded that the protagonist could have made a mistake
  • If the story is set up in the right way, the reader will be tempted to think that the protagonist’s belief isn’t genuine knowledge
  • When presented with these thought experiments, some philosophy students conclude that what these examples show is that knowledge requires full-blown certainty. In these skeptical pressure cases, the evidence is overwhelming, but not 100 percent. It’s an attractive idea, but it doesn’t sit well with the fact that we ordinarily say we know lots of things with much lower probability.
  • Although there is no consensus about how it arises, a promising idea defended by the philosopher David Lewis is that skeptical pressure cases often involve focusing on the possibility of error. Once we start worrying and ruminating about this possibility, no matter how far-fetched, something in our brains causes us to doubt. The philosopher Jennifer Nagel aptly calls this type of effect “epistemic anxiety.”
  • In my own work, I have speculated that an extreme version of this phenomenon is operative in obsessive compulsive disorder
  • The standard response by climate skeptics is a lot like our reaction to skeptical pressure cases. Climate skeptics understand that 97 percent of scientists disagree with them, but they focus on the very tiny fraction of holdouts. As in the lottery case, this focus might be enough to sustain their skepticism.
  • Anti-vaccine proponents, for example, aware that medical professionals disagree with their position, focus on any bit of fringe research that might say otherwise.
  • Skeptical allure can be gripping. Piling on more evidence does not typically shake you out of it, just as making it even more probable that you will lose the lottery does not all of a sudden make you feel like you know your ticket is a loser.
  • One way to counter the effects of skepticism is to stop talking about “knowledge” and switch to talking about probabilities. Instead of saying that you don’t know some claim, try to estimate the probability that it is true. As hedge fund managers, economists, policy researchers, doctors and bookmakers have long been aware, the way to make decisions while managing risk is through probabilities.
  • Once we switch to this perspective, claims to “not know,” like those made by Trump, lose their force and we are pushed to think more carefully about the existing data and engage in cost-benefit analyses.
  • It’s easy to say you don’t know, but it’s harder to commit to an actual low probability estimate in the face of overwhelming contrary evidence.
  • Socrates was correct that awareness of one’s ignorance is virtuous, but philosophers have subsequently uncovered many pitfalls associated with claims of ignorance. An appreciation of these issues can help elevate public discourse on important topics, including the future of our planet.

  • The multiverse idea has two strikes against it, though. First, physicists would refer to it as an unnatural explanation because it simply happened by chance. And second, no real evidence for it exists and we have no experiment that could currently test for it.
