FBI arrests spotlight lessons learned after Charlottesville (opinion) - CNN - 0 views

  • On Thursday, the FBI arrested three men, Patrik J. Mathews, 27, Brian M. Lemley Jr., 33, and William G. Bilbrough IV, 19, with firearms charges, and they had plans, an official said, to attend a Virginia pro-gun rally. This followed Virginia Gov. Ralph Northam's declaration of a temporary state of emergency after authorities learned that extremists hoped to use the anti-gun control rally planned next Monday -- Martin Luther King, Jr. Day -- to incite a violent clash.
  • These arrests add to mounting evidence that a decades-old and violent white-power movement is alive and well, perhaps even gaining strength. White power is a social movement that has united neo-Nazis, Klansmen, skinheads, and militiamen around a shared fear of racial annihilation and cultural change. Since 1983, when movement leaders declared war on the federal government, members of such groups have worked together to bring about a race war.

  • Silver linings aside, it will take many, many more instances of coordinated response to stop a movement generations in the making. In more than a decade of studying the earlier white power movement, I have become familiar with the themes of underground activity that are today clearly drawing from the earlier movement. In the absence of decisive action across multiple institutions, a rich record of criminal activity and violence will continue to provide these activists with a playbook for further chaos.
  • The Base, furthermore, is what experts call "accelerationist," meaning that its members hope to provoke what they see as an inevitable race war. They have conducted paramilitary training in the Pacific Northwest. Both of these strategies date back to the 1980s, when the Order trained in those forests with hopes of provoking the same race war.
  • One of the men arrested Thursday was formerly a reservist in the Canadian Army, where he received training in explosives and demolition, according to the New York Times. This kind of preparation, too, is common among extremists like these. To take just a few representative examples, in the 1960s, Bobby Frank Cherry, a former Marine trained in demolition, helped fellow members of the United Klans of America to bomb the 16th Street Birmingham Baptist Church, killing four black girls.
  • This news out of Virginia shows that there is a real social benefit when people direct their attention to these events -- and sustain the public conversation about the presence of a renewed white-power movement and what it means for our society.

Wine-tasting: it's junk science | Life and style | The Observer - 0 views

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

Do Political Experts Know What They're Talking About? | Wired Science | Wired... - 1 views

  • I often joke that every cable news show should be forced to display a disclaimer, streaming in a loop at the bottom of the screen. The disclaimer would read: “These talking heads have been scientifically proven to not know what they are talking about. Their blather is for entertainment purposes only.” The viewer would then be referred to Tetlock’s most famous research project, which began in 1984.
  • He picked a few hundred political experts – people who made their living “commenting or offering advice on political and economic trends” – and began asking them to make predictions about future events. He had a long list of pertinent questions. Would George Bush be re-elected? Would there be a peaceful end to apartheid in South Africa? Would Quebec secede from Canada? Would the dot-com bubble burst? In each case, the pundits were asked to rate the probability of several possible outcomes. Tetlock then interrogated the pundits about their thought process, so that he could better understand how they made up their minds.
  • Most of Tetlock’s questions had three possible answers; the pundits, on average, selected the right answer less than 33 percent of the time. In other words, a dart-throwing chimp would have beaten the vast majority of professionals. These results are summarized in his excellent Expert Political Judgment.
  • ...5 more annotations...
  • Some experts displayed a top-down style of reasoning: politics as a deductive art. They started with a big-idea premise about human nature, society, or economics and applied it to the specifics of the case. They tended to reach more confident conclusions about the future. And the positions they reached were easier to classify ideologically: that is the Keynesian prediction and that is the free-market fundamentalist prediction and that is the worst-case environmentalist prediction and that is the best case technology-driven growth prediction etc. Other experts displayed a bottom-up style of reasoning: politics as a much messier inductive art. They reached less confident conclusions and they are more likely to draw on a seemingly contradictory mix of ideas in reaching those conclusions (sometimes from the left, sometimes from the right). We called the big-idea experts “hedgehogs” (they know one big thing) and the more eclectic experts “foxes” (they know many, not so big things).
  • The most consistent predictor of consistently more accurate forecasts was “style of reasoning”: experts with the more eclectic, self-critical, and modest cognitive styles tended to outperform the big-idea people (foxes tended to outperform hedgehogs).
  • Lehrer: Can non-experts do anything to encourage a more effective punditocracy?
  • Tetlock: Yes, non-experts can encourage more accountability in the punditocracy. Pundits are remarkably skillful at appearing to go out on a limb in their claims about the future, without actually going out on one. For instance, they often “predict” continued instability and turmoil in the Middle East (predicting the present) but they virtually never get around to telling you exactly what would have to happen to disconfirm their expectations. They are essentially impossible to pin down. If pundits felt that their public credibility hinged on participating in level playing field forecasting exercises in which they must pit their wits against an extremely difficult-to-predict world, I suspect they would be learn, quite quickly, to be more flexible and foxlike in their policy pronouncements.

  • First, making a choice is physically exhausting, literally, so that somebody forced to make a number of decisions in a row is likely to get lazy and dumb.
  • Second, having too many choices can make us less likely to come to a conclusion. In a famous study of the so-called "paradox of choice", psychologists Mark Lepper and Sheena Iyengar found that customers presented with six jam varieties were more likely to buy one than customers offered a choice of 24.
  • ...7 more annotations...
  • Many of our mistakes stem from a central "availability bias." Our brains are computers, and we like to access recently opened files, even though many decisions require a deep body of information that might require some searching. Cheap example: We remember the first, last, and peak moments of certain experiences.
  • The third check against the theory of the rational consumer is the fact that we're social animals. We let our friends and family and tribes do our thinking for us
  • neurologists are finding that many of the biases behavioral economists perceive in decision-making start in our brains. "Brain studies indicate that organisms seem to be on a hedonic treadmill, quickly habituating to homeostasis," McFadden writes. In other words, perhaps our preference for the status quo isn't just figuratively our heads, but also literally sculpted by the hand of evolution inside of our brains.
  • The popular psychological theory of "hyperbolic discounting" says people don't properly evaluate rewards over time. The theory seeks to explain why many groups -- nappers, procrastinators, Congress -- take rewards now and pain later, over and over again. But neurology suggests that it hardly makes sense to speak of "the brain," in the singular, because it's two very different parts of the brain that process choices for now and later. The choice to delay gratification is mostly processed in the frontal system. But studies show that the choice to do something immediately gratifying is processed in a different system, the limbic system, which is more viscerally connected to our behavior, our "reward pathways," and our feelings of pain and pleasure.
  • the final message is that neither the physiology of pleasure nor the methods we use to make choices are as simple or as single-minded as the classical economists thought. A lot of behavior is consistent with pursuit of self-interest, but in novel or ambiguous decision-making environments there is a good chance that our habits will fail us and inconsistencies in the way we process information will undo us.
  • Our brains seem to operate like committees, assigning some tasks to the limbic system, others to the frontal system. The "switchboard" does not seem to achieve complete, consistent communication between different parts of the brain. Pleasure and pain are experienced in the limbic system, but not on one fixed "utility" or "self-interest" scale. Pleasure and pain have distinct neural pathways, and these pathways adapt quickly to homeostasis, with sensation coming from changes rather than levels
  • Social networks are sources of information, on what products are available, what their features are, and how your friends like them. If the information is accurate, this should help you make better choices. On the other hand, it also makes it easier for you to follow the crowd rather than engaging in the due diligence of collecting and evaluating your own information and playing it against your own preferences

Saudi Arabia's crown prince is making a lot of enemies (opinion) - CNN - 0 views

  • Saudi Arabia's Prince Mohammed bin Salman, first in line to inherit the throne from his 81-year-old father, is not a patient man. The 32-year-old is driving a frenetic pace of change in pursuit of three goals: securing his hold on power, transforming Saudi Arabia into a very different country, and pushing back against Iran.
  • In the two years since his father ascended the throne, this favorite son of King Salman bin Abdulaziz has been spectacularly successful at achieving the first item on his agenda. He has become so powerful so fast that observers can hardly believe how brazenly he is dismantling the old sedate system of family consensus, shared privilege and rigid ultraconservatism.
  • He has vowed to improve the status of women, announcing that the ban on women driving will be lifted next year, and limiting the scope of the execrable "guardianship" system, which treats women like children, requiring permission from male guardians for basic activities. He has also restrained the despised religious police. And just last month he called for a return to a "moderate Islam open to the world and all religions," combating extremism and empowering its citizens.

Why 1.2 billion people in China share the same 100 surnames - CNN - 0 views

  • five most common surnames in China -- shared by more than 433 million people, or 30% of the population
  • With 1.37 billion citizens, China has the world's largest population, but has one of the smallest surname pools. Only about 6,000 surnames are in use, according to the Ministry of Public Security. And the vast majority of the population -- almost 86% -- share just 100 of those surnames.
  • To put that in perspective, the United States -- with less than a quarter of China's population -- reported 6.3 million surnames in its 2010 census

      Language!
  • people with rare characters in their names, which aren't compatible with existing computer systems, can get left behind -- pushing many to change their names for the sake of convenience, even if it means abandoning centuries of heritage and language.
  • China's history, full of migration, political turmoil and warfare, meant people's names were often in flux -- which is partly why many have since vanished.
  • People sometimes changed their names for convenience, too -- for instance, simplifying complex characters by adopting similar-sounding ones with fewer strokes. Other times they did it out of superstition, abandoning a name believed to bring ill fortune, said Chen, the associate professor.
  • surnames are lost or die out over time with each new generation as women take on their husbands' surnames.
  • With China roaring into the digital age, nearly everything -- from making appointments to buying train tickets -- has moved online. That meant a world of trouble if you happened to have a rare character in your name, that might not be in the database.
  • China's digitized ID cards made the problem even more pressing. The first generation of these cards allowed people to hand-write their names on -- but the second-generation cards, launched in 2004 and dubbed "smart cards" for their digital features, exclusively used computer-printed text.
    • cvanderloo
       
      Reminds me of requiring people in Guatemala to fill out a form in Spanish even though half of the population doesn't speak spanish.

  • To try to address this, experts have increased the database from 32,000 characters to 70,000 characters, according to the government. They're still working to expand it to include more than 90,000 character
  • This struggle, and the cost of adapting to the modern age, was exemplified in a village in the eastern Shandong province in the late 2000s. Many villagers shared the ancestral name "Shan" -- but when they began applying for the digitized ID cards, local officials advised them to change their surnames to "Xian," a similar-sounding but more common character, according to state-owned news service CNTV.
  • In the end, more than 200 villagers were forced to change their surnames, a source of sorrow for many.

All Can Be Lost: The Risk of Putting Our Knowledge in the Hands of Machines - Nicholas ... - 0 views

  • We rely on computers to fly our planes, find our cancers, design our buildings, audit our businesses. That's all well and good. But what happens when the computer fails?

He reacted quickly, but he did precisely the wrong thing: he jerked back on the yoke, lifting the plane’s nose and reducing its airspeed, instead of pushing the yoke forward to gain velocity.

It's Time for a Real Code of Ethics in Teaching - Noah Berlatsky - The Atlantic - 3 views

  • More 5inShare Email Print A defendant in the Atlanta Public Schools case turns herself in at the Fulton County Jail on April 2. (David Goldman/AP) Earlier this week at The Atlantic, Emily Richmond asked whether high-stakes testing caused the Atlanta schools cheating scandal. The answer, I would argue, is yes... just not in the way you might think. Tests don't cause unethical behavior. But they did cause the Atlanta cheating scandal, and they are doing damage to the teaching profession. The argument that tests do not cause unethical behavior is fairly straightforward, and has been articulated by a number of writers. Jonathan Chait quite correctly points out that unethical behavior occurs in virtually all professions -- and that it occurs particularly when there are clear incentives to succeed. Incentivizing any field increases the impetus to cheat. Suppose journalism worked the way teaching traditionally had. You get hired at a newspaper, and your advancement and pay are dictated almost entirely by your years on the job, with almost no chance of either becoming a star or of getting fired for incompetence. Then imagine journalists changed that and instituted the current system, where you can get really successful if your bosses like you or be fired if they don't. You could look around and see scandal after scandal -- phone hacking! Jayson Blair! NBC's exploding truck! Janet Cooke! Stephen Glass! -- that could plausibly be attributed to this frightening new world in which journalists had an incentive to cheat in order to get ahead. It holds true of any field. If Major League Baseball instituted tenure, and maybe used tee-ball rules where you can't keep score and everybody gets a chance to hit, it could stamp out steroid use. Students have been cheating on tests forever -- massive, systematic cheating, you could say. Why? Because they have an incentive to do well. Give teachers and administrators an incentive for their students to do well, and more of them will cheat. For Chait, then, teaching has just been made more like journalism or baseball; it has gone from an incentiveless occupation to one with incentives.
  • Chait refers to violations of journalistic ethics -- like the phone-hacking scandal -- and suggests they are analogous to Major-League steroid use, and that both are similar to teachers (or students) cheating on tests. But is phone hacking "cheating"
  • Phone hacking was, then, not an example of cheating. It was a violation of professional ethics. And those ethics are not arbitrarily imposed, but are intrinsic to the practice of journalism as a profession committed to public service and to truth.
  • ...8 more annotations...
  • Behaving ethically matters, but how it matters, and what it means, depends strongly on the context in which it occurs.
  • Ethics for teachers is not, apparently, first and foremost about educating their students, or broadening their minds. Rather, ethics for teachers in our current system consists in following the rules. The implicit, linguistic signal being given is that teachers are not like journalists or doctors, committed to a profession and to the moral code needed to achieve their professional goals. Instead, they are like athletes playing games, or (as Chait says) like children taking tests.
  • Using "cheating" as an ethical lens tends to both trivialize and infantilize teacher's work
  • Professions with social respect and social capital, like doctors and lawyers, collaborate in the creation of their own standards. The assumption is that those standards are intrinsic to the profession's goals, and that, therefore, professionals themselves are best equipped to establish and monitor them. Teachers' standards, though, are imposed from outside -- as if teachers are children, or as if teaching is a game.
  • High-stakes testing, then, does leads to cheating. It does not create unethical behavior -- but it does create the particular unethical behavior of "cheating."
  • We have reached a point where we can only talk about the ethics of the profession in terms of cheating or not cheating, as if teachers' main ethical duty is to make sure that scantron bubbles get filled in correctly. Teachers, like journalists, should have a commitment to truth; like doctors, they have a duty of care. Translating those commitments and duties into a bureaucratized measure of cheating-or-not-cheating diminishes ethic
  • For teachers it is, literally, demoralizing. It severs the moral experience of teaching from the moral evaluation of teaching, which makes it almost impossible for good teachers (in all the senses of "good") to stay in the system.
  • We need better ethics for teachers -- ethics that treat them as adults and professionals, not like children playing games.

What Is Synesthesia? Definition and Types - 0 views

  • The term "synesthesia" comes from the Greek words&nbsp;syn, which means "together", and&nbsp;aisthesis, which means "sensation." Synesthesia is a perception in which stimulating one sensory or cognitive pathway&nbsp; causes experiences in another sense or cognitive pathway. In other words, a sense or concept is connected to a different sense or concept, such as hearing a color or tasting a word. The connection between pathways is involuntary and consistent over time, rather than conscious or arbitrary.
  • Types of SynesthesiaThere are many different types of synesthesia, but they may be categorized as falling into one of two groups: associative&nbsp;synesthesia and projective synesthesia. An associate feels a connection between a stimulus and a sense, w
  • There are at least 80 known types of synesthesia, but some are more common than others: Chromesthesia:&nbsp;In this common form of synesthesia, sounds and colors are associated with each other. For example, the musical note "D" may correspond to seeing the color green.Grapheme-color synesthesia: This is a common form of synesthesia characterized by seeing graphemes (letter or numerals) shaded with a color. Synesthetes don't associate the same colors for a grapheme as each other, although the letter "A" does appear to be red to many individuals. Persons who experience grapheme-color synesthesia sometimes report seeing impossible colors when red and green or blue and yellow graphemes appear next to each other in a word or number. Number form: A number form is a mental shape or map of numbers resulting from seeing or thinking about numbers.Lexical-gustatory synesthesia: This a rare type of synesthesia in which hearing a word results in tasting a flavor. For example, a person's name might taste like chocolate.Mirror-touch synesthesia: While rare, mirror-touch synesthesia is noteworthy because it can be disruptive to a synesthete's life. In this form of synesthesia, an individual feels the same sensation in response to a stimulus as another person. For example, seeing a person being tapped on the shoulder would cause the synesthete to feel a tap on
  • ...3 more annotations...
  • How Synesthesia WorksScientists have yet to make a definitive determination of the mechanism of synesthesia. It may be due to increased cross-talk between specialized regions of the brain. Another possible mechanism is that inhibition in a neural pathway is reduced in synesthetes, allowing multi-sensory processing of stimuli. Some researchers believe synesthesia is based on the way the brain extracts and assigns the meaning of a stimulus (ideasthesia).
  • Who Has Synesthesia?Julia Simner, a psychologist studying synesthesia at&nbsp;of the University of Edinburgh, estimates at least 4% of the population has synesthesia and that over 1% of people have grapheme-color synesthesia (colored numbers and letters). More women have synesthesia than men. Some research suggests the incidenc
  • Can You Develop Synesthesia?There are documented cases of non-synesthetes developing synesthesia. Specifically, head trauma, stroke, brain tumors, and temporal lobe epilepsy may produce synesthesia. Temporary synesthesia may result from exposure to the psychedelic drugs mescaline or LSD, from sensory deprivation, or from meditation.

  • At some centers, he said, brain surgeons do not even order frozen sections because they do not trust them and prefer to wait for tissue processing after the surgery, which may take weeks to complete.
  • Some types of brain tumor are so rare that there is not enough data on them to train an A.I. system, so the system in the study was designed to essentially toss out samples it could not identify.

The American Scholar: The Disadvantages of an Elite Education - William Deresiewicz - 1 views

  • the last thing an elite education will teach you is its own inadequacy
  • I’m talking about the whole system in which these skirmishes play out. Not just the Ivy League and its peer institutions, but also the mechanisms that get you there in the first place: the private and affluent public “feeder” schools, the ever-growing parastructure of tutors and test-prep courses and enrichment programs, the whole admissions frenzy and everything that leads up to and away from it. The message, as always, is the medium. Before, after, and around the elite college classroom, a constellation of values is ceaselessly inculcated.
  • The first disadvantage of an elite education, as I learned in my kitchen that day, is that it makes you incapable of talking to people who aren’t like you. Elite schools pride themselves on their diversity, but that diversity is almost entirely a matter of ethnicity and race. With respect to class, these schools are largely—indeed increasingly—homogeneous. Visit any elite campus in our great nation and you can thrill to the heartwarming spectacle of the children of white businesspeople and professionals studying and playing alongside the children of black, Asian, and Latino businesspeople and professionals.
  • ...34 more annotations...
  • My education taught me to believe that people who didn’t go to an Ivy League or equivalent school weren’t worth talking to, regardless of their class. I was given the unmistakable message that such people were beneath me.
  • The existence of multiple forms of intelligence has become a commonplace, but however much elite universities like to sprinkle their incoming classes with a few actors or violinists, they select for and develop one form of intelligence: the analytic.
  • Students at places like Cleveland State, unlike those at places like Yale, don’t have a platoon of advisers and tutors and deans to write out excuses for late work, give them extra help when they need it, pick them up when they fall down.
  • When people say that students at elite schools have a strong sense of entitlement, they mean that those students think they deserve more than other people because their SAT scores are higher.
  • The political implications should be clear. As John Ruskin told an older elite, grabbing what you can get isn’t any less wicked when you grab it with the power of your brains than with the power of your fists.
  • students at places like Yale get an endless string of second chances. Not so at places like Cleveland State.
  • The second disadvantage, implicit in what I’ve been saying, is that an elite education inculcates a false sense of self-worth. Getting to an elite college, being at an elite college, and going on from an elite college—all involve numerical rankings: SAT, GPA, GRE. You learn to think of yourself in terms of those numbers. They come to signify not only your fate, but your identity; not only your identity, but your value.
  • For the elite, there’s always another extension—a bailout, a pardon, a stint in rehab—always plenty of contacts and special stipends—the country club, the conference, the year-end bonus, the dividend.
  • In short, the way students are treated in college trains them for the social position they will occupy once they get out. At schools like Cleveland State, they’re being trained for positions somewhere in the middle of the class system, in the depths of one bureaucracy or another. They’re being conditioned for lives with few second chances, no extensions, little support, narrow opportunity—lives of subordination, supervision, and control, lives of deadlines, not guidelines. At places like Yale, of course, it’s the reverse.
  • Elite schools nurture excellence, but they also nurture what a former Yale graduate student I know calls “entitled mediocrity.”
  • An elite education gives you the chance to be rich—which is, after all, what we’re talking about—but it takes away the chance not to be. Yet the opportunity not to be rich is one of the greatest opportunities with which young Americans have been blessed. We live in a society that is itself so wealthy that it can afford to provide a decent living to whole classes of people who in other countries exist (or in earlier times existed) on the brink of poverty or, at least, of indignity. You can live comfortably in the United States as a schoolteacher, or a community organizer, or a civil rights lawyer, or an artist
  • The liberal arts university is becoming the corporate university, its center of gravity shifting to technical fields where scholarly expertise can be parlayed into lucrative business opportunities.
  • You have to live in an ordinary house instead of an apartment in Manhattan or a mansion in L.A.; you have to drive a Honda instead of a BMW or a Hummer; you have to vacation in Florida instead of Barbados or Paris, but what are such losses when set against the opportunity to do work you believe in, work you’re suited for, work you love, every day of your life? Yet it is precisely that opportunity that an elite education takes away. How can I be a schoolteacher—wouldn’t that be a waste of my expensive education?
  • Isn’t it beneath me? So a whole universe of possibility closes, and you miss your true calling.
  • This is not to say that students from elite colleges never pursue a riskier or less lucrative course after graduation, but even when they do, they tend to give up more quickly than others.
  • But if you’re afraid to fail, you’re afraid to take risks, which begins to explain the final and most damning disadvantage of an elite education: that it is profoundly anti-intellectual.
  • being an intellectual is not the same as being smart. Being an intellectual means more than doing your homework.
  • The system forgot to teach them, along the way to the prestige admissions and the lucrative jobs, that the most important achievements can’t be measured by a letter or a number or a name. It forgot that the true purpose of education is to make minds, not careers.
  • Being an intellectual means, first of all, being passionate about ideas—and not just for the duration of a semester, for the sake of pleasing the teacher, or for getting a good grade.
  • Only a small minority have seen their education as part of a larger intellectual journey, have approached the work of the mind with a pilgrim soul. These few have tended to feel like freaks, not least because they get so little support from the university itself. Places like Yale, as one of them put it to me, are not conducive to searchers. GA_googleFillSlot('Rectangle_InArticle_Right'); GA_googleCreateDomIframe("google_ads_div_Rectangle_InArticle_Right_ad_container" ,"Rectangle_InArticle_Right"); Places like Yale are simply not set up to help students ask the big questions
  • Professors at top research institutions are valued exclusively for the quality of their scholarly work; time spent on teaching is time lost. If students want a conversion experience, they’re better off at a liberal arts college.
  • When elite universities boast that they teach their students how to think, they mean that they teach them the analytic and rhetorical skills necessary for success in law or medicine or science or business.
  • Although the notion of breadth is implicit in the very idea of a liberal arts education, the admissions process increasingly selects for kids who have already begun to think of themselves in specialized terms—the junior journalist, the budding astronomer, the language prodigy. We are slouching, even at elite schools, toward a glorified form of vocational training.
  • There’s a reason elite schools speak of training leaders, not thinkers—holders of power, not its critics. An independent mind is independent of all allegiances, and elite schools, which get a large percentage of their budget from alumni giving, are strongly invested in fostering institutional loyalty.
  • At a school like Yale, students who come to class and work hard expect nothing less than an A-. And most of the time, they get it.
  • Yet there is a dimension of the intellectual life that lies above the passion for ideas, though so thoroughly has our culture been sanitized of it that it is hardly surprising if it was beyond the reach of even my most alert students. Since the idea of the intellectual emerged in the 18th century, it has had, at its core, a commitment to social transformation. Being an intellectual means thinking your way toward a vision of the good society and then trying to realize that vision by speaking truth to power.
  • It takes more than just intellect; it takes imagination and courage.
  • Being an intellectual begins with thinking your way outside of your assumptions and the system that enforces them. But students who get into elite schools are precisely the ones who have best learned to work within the system, so it’s almost impossible for them to see outside it, to see that it’s even there.
  • Paradoxically, the situation may be better at second-tier schools and, in particular, again, at liberal arts colleges than at the most prestigious universities. Some students end up at second-tier schools because they’re exactly like students at Harvard or Yale, only less gifted or driven. But others end up there because they have a more independent spirit. They didn’t get straight A’s because they couldn’t be bothered to give everything in every class. They concentrated on the ones that meant the most to them or on a single strong extracurricular passion or on projects that had nothing to do with school
  • I’ve been struck, during my time at Yale, by how similar everyone looks. You hardly see any hippies or punks or art-school types, and at a college that was known in the ’80s as the Gay Ivy, few out lesbians and no gender queers. The geeks don’t look all that geeky; the fashionable kids go in for understated elegance. Thirty-two flavors, all of them vanilla.
  • The most elite schools have become places of a narrow and suffocating normalcy. Everyone feels pressure to maintain the kind of appearance—and affect—that go with achievement
  • Now that students are in constant electronic contact, they never have trouble finding each other. But it’s not as if their compulsive sociability is enabling them to develop deep friendships.
  • What happens when busyness and sociability leave no room for solitude? The ability to engage in introspection, I put it to my students that day, is the essential precondition for living an intellectual life, and the essential precondition for introspection is solitude
  • the life of the mind is lived one mind at a time: one solitary, skeptical, resistant mind at a time. The best place to cultivate it is not within an educational system whose real purpose is to reproduce the class system.

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

  • He proves nothing that he doesn’t simultaneously subvert a little; he makes no over-arching argument about the way humans must live; he has no logician’s architecture or religious doctrine. He slips past all those familiar means of telling other people what’s good for them, and simply explains what has worked for him and others and leaves the reader empowered to forge her own future
  • You can see its eccentric power by considering the alternative ways of doing what Montaigne was doing. Think of contemporary self-help books – and all the fake certainty and rigid formulae they contain. Or think of a hideous idea like “the purpose-driven life” in which everything must be forced into the box of divine guidance in order to really live at all. Think of the stringency of Christian disciplines – say, the spiritual exercises of Ignatius of Loyola – and marvel at how Montaigne offers an entirely different and less compelling way to live. Think of the rigidity of Muslim practice and notice how much lee-way Montaigne gives to sin
  • This is a non-philosophical philosophy. It is a theory of practical life as told through one man’s random and yet not-so-random reflections on his time on earth. And it is shot through with doubt. Even the maxims that Montaigne embraces for living are edged with those critical elements of Montaigne’s thought that say “as far as I know”

  • Is this enough? Or is it rather a capitulation to relativism, a manifesto for political quietism, a worldview that treats injustice as something to be abhorred but not constantly fought against? This might be seen as the core progressive objection to the way of Montaigne. Or is his sensibility in an age of religious terror and violence and fanaticism the only ultimate solution we have?
  • here’s what we do know. We are fallible beings; we have nothing but provisional knowledge; and we will die. And this is enough. This does not mean we should give up inquiring or seeking to understand. Skepticism is not nihilism. It doesn’t posit that there is no truth; it merely notes that if truth exists, it is inherently beyond our ultimate grasp. And accepting those limits is the first step toward sanity, toward getting on with life. This is what I mean by conservatism.
  • you can find in philosophy any number of clues about how to live; you can even construct them into an ideology that explains all of human life and society – like Marxism or free market fundamentalism or a Nietzschean will to power. But as each totalist system broke down upon my further inspection, I found myself returning to Montaigne and the tradition of skepticism he represents
  • If I were to single out one theme of Montaigne’s work that has stuck with me, it would be this staring of death in the face, early and often, and never flinching. It is what our culture refuses to do much of the time, thereby disempowering us in the face of our human challenges.

Shady Science: How the Brain Remembers Colors - 0 views

  • When you bring home the wrong color of paint from the hardware store, it may not be your foggy memory at fault
  • Flombaum and his colleagues conducted four experiments on four different groups of people.
  • while the human brain can distinguish between millions of colors, it has difficulty remembering specific shades.
  • ...7 more annotations...
  • The exercise was designed to find the perceived boundaries between colors, the researchers said
  • scientists showed different people the same colors, but this time they asked them to find the "best example" of a particular color.
  • researchers showed participants colored squares, and asked them to select the best match on the color wheel. In a fourth experiment, another group of participants completed the same task, but there was a delay of 90 milliseconds between when each color square was displayed and when they were asked to select the best match on the color wheel.
  • This tendency to lump colors together could explain why it's so hard to match the color of house paint based on memory alone, the researchers said
  • categories are indeed important in how people identify and remember colors.
  • participants who were asked to name the colors reliably saw five hues: blue, yellow, pink, purple and green
  • "Where that fuzzy naming happened, those are the boundaries"
