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.

  • 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.

Give the Data to the People - NYTimes.com - 1 views

  • Johnson & Johnson announced that it was making all of its clinical trial data available to scientists around the world. It has hired my group, Yale University Open Data Access Project, or YODA, to fully oversee the release of the data. Everything in the company’s clinical research vaults, including unpublished raw data, will be available for independent review.
  • Today, more than half of the clinical trials in the United States, including many sponsored by academic and governmental institutions, are not published within two years of their completion. Often they are never published at all.
  • As a result, evidence-based medicine is, at best, based on only some of the evidence.
  • ...3 more annotations...
  • Even when studies are published, the actual data are usually not made available. End users of research — patients, doctors and policy makers — are implicitly told by a single group of researchers to “take our word for it.” They are often forced to accept the report without the prospect of other independent scientists’ reproducing the findings — a violation of a central tenet of the scientific method.
  • Companies worry that their competitors will benefit, that lawyers will take advantage, that incompetent scientists will misconstrue the data and come to mistaken conclusions.
  • We require those who want the data to submit a proposal and identify their research team, funding and any conflicts of interest. They have to complete a short course on responsible conduct and sign an agreement that restricts them to their proposed research question. Most important, they must agree to share whatever they find. And we exclude applicants who seek data for commercial or legal purposes. Our intent is not to be tough gatekeepers, but to ensure that the data are used in a transparent way and contribute to overall scientific knowledge.

What's Lost as Handwriting Fades - NYTimes.com - 3 views

  • Children who had not yet learned to read and write were presented with a letter or a shape on an index card and asked to reproduce it in one of three ways: trace the image on a page with a dotted outline, draw it on a blank white sheet, or type it on a computer. They were then placed in a brain scanner and shown the image again.
  • When children had drawn a letter freehand, they exhibited increased activity in three areas of the brain that are activated in adults when they read and write
  • By contrast, children who typed or traced the letter or shape showed no such effect. The activation was significantly weaker.
  • ...7 more annotations...
  • Dr. James attributes the differences to the messiness inherent in free-form handwriting: Not only must we first plan and execute the action in a way that is not required when we have a traceable outline, but we are also likely to produce a result that is highly variable.
  • That variability may itself be a learning tool. “When a kid produces a messy letter,” Dr. James said, “that might help him learn it.”
  • printing, cursive writing, and typing on a keyboard are all associated with distinct and separate brain patterns — and each results in a distinct end product.
  • When the children composed text by hand, they not only consistently produced more words more quickly than they did on a keyboard, but expressed more ideas. And brain imaging in the oldest subjects suggested that the connection between writing and idea generation went even further. When these children were asked to come up with ideas for a composition, the ones with better handwriting exhibited greater neural activation in areas associated with working memory — and increased overall activation in the reading and writing networks.
  • In alexia, or impaired reading ability, some individuals who are unable to process print can still read cursive, and vice versa — suggesting that the two writing modes activate separate brain networks and engage more cognitive resources than would be the case with a single approach.
  • in both laboratory settings and real-world classrooms, students learn better when they take notes by hand than when they type on a keyboard. Contrary to earlier studies attributing the difference to the distracting effects of computers, the new research suggests that writing by hand allows the student to process a lecture’s contents and reframe it — a process of reflection and manipulation that can lead to better understanding and memory encoding.
  • “With handwriting, the very act of putting it down forces you to focus on what’s important,” he said. He added, after pausing to consider, “Maybe it helps you think better.”

Is This the Future of Punctuation!? - WSJ.com - 1 views

  • Punctuation arouses strong feelings. You have probably come across the pen-wielding vigilantes who skulk around defacing movie posters and amending handwritten signs that advertise "Rest Room's" or "Puppy's For Sale." People fuss about punctuation not only because it clarifies meaning but also because its neglect appears to reflect wider social decline. And while the big social battles seem intractable, smaller battles over the use of the apostrophe feel like they can be won. Enlarge ImageClose Yet the status of this and other cherished marks has long been precarious. The story of punctuation is one of comings and goings.
  • How might punctuation now evolve? The dystopian view is that it will vanish. I find this conceivable, though not likely. But we can see harbingers of such change: editorial austerity with commas, the newsroom preference for the period over all other marks, and the taste for visual crispness. Though it is not unusual to hear calls for new punctuation, the marks proposed tend to cannibalize existing ones. In this vein, you may have encountered the interrobang , which signals excited disbelief. Such marks are symptoms of an increasing tendency to punctuate for rhetorical rather than grammatical effect. Instead of presenting syntactical and logical relationships, punctuation reproduces the patterns of speech.
  • Defenders of the apostrophe insist that it minimizes ambiguity, but there are few situations in which its omission can lead to real misunderstanding.

Education and class: America's new aristocracy | The Economist - 0 views

  • Because America never had kings or lords, it sometimes seems less inclined to worry about signs that its elite is calcifying.
  • Thomas Jefferson drew a distinction between a natural aristocracy of the virtuous and talented, which was a blessing to a nation, and an artificial aristocracy founded on wealth and birth, which would slowly strangle it.
  • When the robber barons accumulated fortunes that made European princes envious, the combination of their own philanthropy, their children’s extravagance and federal trust-busting meant that Americans never discovered what it would be like to live in a country where the elite could reliably reproduce themselves.

  • Intellectual capital drives the knowledge economy, so those who have lots of it get a fat slice of the pie. And it is increasingly heritable. Far more than in previous generations, clever, successful men marry clever, successful women.
  • Such “assortative mating” increases inequality by 25%, by one estimate, since two-degree households typically enjoy two large incomes.
  • Power couples conceive bright children and bring them up in stable homes
  • They stimulate them relentlessly: children of professionals hear 32m more words by the age of four than those of parents on welfare. They move to pricey neighbourhoods with good schools, spend a pa
  • The link between parental income and a child’s academic success has grown stronger, as clever people become richer and splash out on their daughter’s Mandarin tutor, and education matters more than it used to, because the demand for brainpower has soared.
  • For those at the top of the pile, moving straight from the best universities into the best jobs, the potential rewards are greater than they have ever been.
  • None of this is peculiar to America, but the trend is most visible there. This is partly because the gap between rich and poor is bigger than anywhere else in the rich world
  • It is also because its education system favours the well-off more than anywhere else in the rich world. Thanks to hyperlocal funding, America is one of only three advanced countries where the government spends more on schools in rich areas than in poor ones.
  • Its university fees have risen 17 times as fast as median incomes since 1980, partly to pay for pointless bureaucracy and flashy buildings. And many universities offer “legacy” preferences, favouring the children of alumni in admissions.
  • There is no substitute for parents who talk and read to their babies, but good nurseries can help, especially for the most struggling families; and America scores poorly by international standards
  • The solution is not to discourage rich people from investing in their children, but to do a lot more to help clever kids who failed to pick posh parents
  • America’s universities need an injection of meritocracy. Only a handful, such as Caltech, admit applicants solely on academic merit. All should.
  • Loosening the link between birth and success would make America richer—far too much talent is currently wasted. It might also make the nation more cohesive. If Americans suspect that the game is rigged, they may be tempted to vote for demagogues

Book Review: 'A New History of Life' by Peter Ward and Joe Kirschvink - WSJ - 0 views

  • I imagine that physicists are similarly deluged with revelations about how to build a perpetual-motion machine or about the hitherto secret truth behind relativity. And so I didn’t view the arrival of “A New History of Life” with great enthusiasm.
  • subtitle breathlessly promises “radical new discoveries about the origins and evolution of life on earth,” while the jacket copy avers that “our current paradigm for understanding the history of life on Earth dates back to Charles Darwin’s time, yet scientific advances of the last few decades have radically reshaped that aging picture.”
  • authors Peter Ward and Joe Kirschvink are genuine scientists—paleontologists, to be exact. And they can write.
  • ...16 more annotations...
  • even genuine scientists are human and as such susceptible to the allure of offering up new paradigms (as the historian of science Thomas Kuhn put it)
  • paleontologist Stephen Jay Gould insisted that his conception of “punctuated equilibria” (a kind of Marxist biology that blurred the lines between evolution and revolution), which he developed along with fellow paleontologist Niles Eldredge, upended the traditional Darwinian understanding of how natural selection works.
  • This notion doesn’t constitute a fundamental departure from plain old evolution by natural selection; it simply italicizes that sometimes the process is comparatively rapid, other times slower.
  • In addition, they have long had a peculiar perspective on evolution, because of the limitations of the fossil record
  • Darwin was a pioneering geologist as well as the greatest of all biologists, and his insights were backgrounded by the key concept of uniformitarianism, as advocated by Charles Lyell, his friend and mentor
  • previously regnant paradigm among geologists had been “catastrophism
  • fossil record was therefore seen as reflecting the creation and extinction of new species by an array of dramatic and “unnatural” dei ex machina.
  • Of late, however, uniformitarianism has been on a losing streak. Catastrophism is back, with a bang . . . or a flood, or a burst of extraterrestrial radiation, or an onslaught of unpleasant, previously submerged chemicals
  • This emphasis on catastrophes is the first of a triad of novelties on which “A New History of Life” is based. The second involves an enhanced role for some common but insufficiently appreciated inorganic molecules, notably carbon dioxide, oxygen and hydrogen sulfide.
  • Life didn’t so much unfold smoothly over hundreds of millions of years as lurch chaotically in response to diverse crises and opportunities: too much oxygen, too little carbon dioxide, too little oxygen, too much carbon dioxide, too hot, too cold
  • So far, so good, except that in their eagerness to emphasize what is new and different, the authors teeter on the verge of the same trap as Gould: exaggerating the novelty of their own ideas.
  • Things begin to unravel when it comes to the third leg of Messrs. Ward and Kirschvink’s purported paradigmatic novelty: a supposed role for ecosystems—rain forests, deserts, rivers, coral reefs, deep-sea vents—as units of evolutionary change
  • “While the history of life may be populated by species,” they write, “it has been the evolution of ecosystems that has been the most influential factor in arriving at the modern-day assemblage of life. . . . [W]e know that on occasion in the deep past entirely new ecosystems appear, populated by new kinds of life.” True enough, but it is those “new kinds of life,” not whole ecosystems, upon which natural selection acts.
  • One of the most common popular misconceptions about evolution is that it proceeds “for the good of the species.”
  • The problem is that smaller, nimbler units are far more likely to reproduce differentially than are larger, clumsier, more heterogeneous ones. Insofar as ecosystems are consequential for evolution—and doubtless they are—it is because, like occasional catastrophes, they provide the immediate environment within which something not-so-new is acted out.
  • This is natural selection doing its same-old, same-old thing: acting by a statistically potent process of variation combined with selective retention and differential reproduction, a process that necessarily operates within the particular ecosystem that a given lineage occupies.

The Government's Bad Diet Advice - NYTimes.com - 0 views

  • How did experts get it so wrong?
  • the primary problem is that nutrition policy has long relied on a very weak kind of science: epidemiological, or “observational,” studies in which researchers follow large groups of people over many years. But even the most rigorous epidemiological studies suffer from a fundamental limitation. At best they can show only association, not causation.
  • Instead of accepting that this evidence was inadequate to give sound advice, strong-willed scientists overstated the significance of their studies.
  • ...7 more annotations...
  • In clearing our plates of meat, eggs and cheese (fat and protein), we ate more grains, pasta and starchy vegetables (carbohydrates). Over the past 50 years, we cut fat intake by 25 percent and increased carbohydrates by more than 30 percent, according to a new analysis of government data. Yet recent science has increasingly shown that a high-carb diet rich in sugar and refined grains increases the risk of obesity, diabetes and heart disease — much more so than a diet high in fat and cholesterol.
  • In 2013, government advice to reduce salt intake (which remains in the current report) was contradicted by an authoritative Institute of Medicine study. And several recent meta-analyses have cast serious doubt on whether saturated fats are linked to heart disease, as the dietary guidelines continue to assert.
  • Much of the epidemiological data underpinning the government’s dietary advice comes from studies run by Harvard’s school of public health. In 2011, directors of the National Institute of Statistical Sciences analyzed many of Harvard’s most important findings and found that they could not be reproduced in clinical trials.
  • Today, we are poised to make the same mistakes. The committee’s new report also advised eliminating “lean meat” from the list of recommended healthy foods, as well as cutting back on red and processed meats. Fewer protein choices will likely encourage Americans to eat even more carbs. It will also have policy implications: Meat could be limited in school lunches and other federal food programs.
  • It’s possible that a mostly meatless diet could be healthy for all Americans — but then again, it might not be. We simply do not know. There are no rigorous clinical trials on such a diet, and although epidemiological data exists for adult vegetarians, there is none for children.
  • We have to start looking more skeptically at epidemiological studies and rethinking nutrition policy from the ground up.
  • Until then, we would be wise to return to what worked better for previous generations: a diet that included fewer grains, less sugar and more animal foods like meat, full-fat dairy and eggs

Technology Imperialism, the Californian Ideology, and the Future of Higher Education - 2 views

  • What I hope to make explicit today is how much California – the place, the concept, “the dream machine” – shapes (wants to shape) the future of technology and the future of education.
  • In an announcement on Facebook – of course – Zuckerberg argued that “connectivity is a human right.”
  • As Zuckerberg frames it at least, the “human right” in this case is participation in the global economy
  • ...34 more annotations...
  • This is a revealing definition of “human rights,” I’d argue, particularly as it’s one that never addresses things like liberty, equality, or justice. It never addresses freedom of expression or freedom of assembly or freedom of association.
  • in certain countries, a number of people say they do not use the Internet yet they talk about how much time they spend on Facebook. According to one survey, 11% of Indonesians who said they used Facebook also said they did not use the Internet. A survey in Nigeria had similar results:
  • Evgeny Morozov has described this belief as “Internet-centrism,” an ideology he argues permeates the tech industry, its PR wing the tech blogosphere, and increasingly government policy
  • “Internet-centrism” describes the tendency to see “the Internet” – Morozov uses quotations around the phrase – as a new yet unchanging, autonomous, benevolent, and inevitable socio-technological development. “The Internet” is a master framework for how all institutions will supposedly operate moving forward
  • “The opportunity to connect” as a human right assumes that “connectivity” will hasten the advent of these other rights, I suppose – that the Internet will topple dictatorships, for example, that it will extend participation in civic life to everyone and, for our purposes here at this conference, that it will “democratize education.”
  • Empire is not simply an endeavor of the nation-state – we have empire through technology (that’s not new) and now, the technology industry as empire.
  • Facebook is really just synecdochal here, I should add – just one example of the forces I think are at play, politically, economically, technologically, culturally.
  • it matters at the level of ideology. Infrastructure is ideological, of course. The new infrastructure – “the Internet” if you will – has a particular political, economic, and cultural bent to it. It is not neutral.
  • This infrastructure matters. In this case, this is a French satellite company (Eutelsat). This is an American social network (Facebook). Mark Zuckerberg’s altruistic rhetoric aside, this is their plan – an economic plan – to monetize the world’s poor.
  • The content and the form of “connectivity” perpetuate imperialism, and not only in Africa but in all of our lives. Imperialism at the level of infrastructure – not just cultural imperialism but technological imperialism
  • “The Silicon Valley Narrative,” as I call it, is the story that the technology industry tells about the world – not only the world-as-is but the world-as-Silicon-Valley-wants-it-to-be.
  • To better analyze and assess both technology and education technology requires our understanding of these as ideological, argues Neil Selwyn – “‘a site of social struggle’ through which hegemonic positions are developed, legitimated, reproduced and challenged.”
  • This narrative has several commonly used tropes
  • It often features a hero: the technology entrepreneur. Smart. Independent. Bold. Risk-taking. White. Male
  • “The Silicon Valley narrative” invokes themes like “innovation” and “disruption.” It privileges the new; everything else that can be deemed “old” is viewed as obsolete.
  • It contends that its workings are meritocratic: anyone who hustles can make it.
  • “The Silicon Valley narrative” fosters a distrust of institutions – the government, the university. It is neoliberal. It hates paying taxes.
  • “The Silicon Valley narrative” draws from the work of Ayn Rand; it privileges the individual at all costs; it calls this “personalization.”
  • “The Silicon Valley narrative” does not neatly co-exist with public education. We forget this at our peril. This makes education technology, specifically, an incredibly fraught area.
  • Here’s the story I think we like to hear about ed-tech, about distance education, about “connectivity” and learning: Education technology is supportive, not exploitative. Education technology opens, not forecloses, opportunities. Education technology is driven by a rethinking of teaching and learning, not expanding markets or empire. Education technology meets individual and institutional and community goals.
  • That’s not really what the “Silicon Valley narrative” says about education
  • It is interested in data extraction and monetization and standardization and scale. It is interested in markets and return on investment. “Education is broken,” and technology will fix it
  • If “Silicon Valley” isn’t quite accurate, then I must admit that the word “narrative” is probably inadequate too
  • The better term here is “ideology.”
  • Facebook is “the Internet” for a fairly sizable number of people. They know nothing else – conceptually, experientially. And, let’s be honest, Facebook wants to be “the Internet” for everyone.
  • We tend to not see technology as ideological – its connections to libertarianism, neoliberalism, global capitalism, empire.
  • The California ideology ignores race and labor and the water supply; it is sustained by air and fantasy. It is built upon white supremacy and imperialism.
  • As is the technology sector, which has its own history, of course, in warfare and cryptography.
  • So far this year, some $3.76 billion of venture capital has been invested in education technology – a record-setting figure. That money will change the landscape – that’s its intention. That money carries with it a story about the future; it carries with it an ideology.
  • When a venture capitalist says that “software is eating the world,” we can push back on the inevitability implied in that. We can resist – not in the name of clinging to “the old” as those in educational institutions are so often accused of doing – but we can resist in the name of freedom and justice and a future that isn’t dictated by the wealthiest white men in Hollywood or Silicon Valley.
  • We in education would be naive, I think, to think that the designs that venture capitalists and technology entrepreneurs have for us would be any less radical than creating a new state, like Draper’s proposed state of Silicon Valley, that would enormously wealthy and politically powerful.
  • When I hear talk of “unbundling” in education – one of the latest gerunds you’ll hear venture capitalists and ed-tech entrepreneurs invoke, meaning the disassembling of institutions into products and services – I can’t help but think of the “unbundling” that Draper wished to do to my state: carving up land and resources, shifting tax revenue and tax burdens, creating new markets, privatizing public institutions, redistributing power and doing so explicitly not in the service of equity or justice.
  • I want to show you this map, a proposal – a failed proposal, thankfully – by venture capitalist Tim Draper to split the state of California into six separate states: Jefferson, North California, Silicon Valley, Central California, West California, and South California. The proposal, which Draper tried to collect enough signatures to get on the ballot in California, would have created the richest state in the US – Silicon Valley would be first in per-capita income. It would also have created the nation’s poorest state, Central California, which would rank even below Mississippi.
  • that’s not all that Silicon Valley really does.

Narcissism Is Increasing. So You're Not So Special. - The New York Times - 1 views

  • A 2010 study in the journal Social Psychological and Personality Science found that the percentage of college students exhibiting narcissistic personality traits, based on their scores on the Narcissistic Personality Inventory, a widely used diagnostic test, has increased by more than half since the early 1980s, to 30 percent. In their book “Narcissism Epidemic,” the psychology professors Jean M. Twenge and W. Keith Campbell show that narcissism has increased as quickly as obesity has since the 1980s. Even our egos are getting fat.
  • This is a costly problem. While full-blown narcissists often report high levels of personal satisfaction, they create havoc and misery around them. There is overwhelming evidence linking narcissism with lower honesty and raised aggression.
  • narcissism isn’t an either-or characteristic. It’s more of a set of progressive symptoms (like alcoholism) than an identifiable state (like diabetes). Millions of Americans exhibit symptoms, but still have a conscience and a hunger for moral improvement. At the very least, they really don’t want to be terrible people.

  • Rousseau wrote about “amour-propre,” a kind of self-love based on the opinions of others. He considered it unnatural and unhealthy, and believed that arbitrary social comparison led to people wasting their lives trying to look and sound attractive to others.
  • Narcissus falls in love not with himself, but with his reflection. In the modern version, Narcissus would fall in love with his own Instagram feed, and starve himself to death while compulsively counting his followers.
  • If our egos are obese with amour-propre, social media can indeed serve up the empty emotional carbs we crave. Instagram and the like doesn’t create a narcissist, but studies suggest it acts as an accelerant — a near ideal platform to facilitate what psychologists call “grandiose exhibitionism.”
  • No doubt you have seen this in others, and maybe even a little of it in yourself as you posted a flattering selfie — and then checked back 20 times for “likes.”
  • A healthy self-love that leads to true happiness is what Rousseau called “amour de soi.” It builds up one’s intrinsic well-being, as opposed to feeding shallow cravings to be admired.
  • First, take the Narcissistic Personality Inventory test.
  • Here is an individual self-improvement strategy that combines a healthy self-love (for Valentine’s Day) with a small sacrifice (possibly for Lent).
  • Cultivating amour de soi requires being fully alive at this moment, as opposed to being virtually alive while wondering what others think. The soulful connection with another person, the enjoyment of a beautiful hike alone (not shared on Facebook) or a prayer of thanks over your sleeping child (absent a #blessed tweet) could be considered expressions of amour de soi.
  • Second, get rid of the emotional junk food that is feeding any unhealthy self-obsession. Make a list of opinions to disregard — especially those of flatterers and critics — and review the list each day. Resolve not to waste a moment trying to impress others,
  • Third, go on a social media fast. Post to communicate, praise and learn — never to self-promote.
  • As for clinically significant narcissism—along with greed, invidious prejudice, and habitual lying—it is simply another one of our anti-social behaviors that mutated from our basic genetic drives…in this case the drive to survive. The opposite of narcissism is empathy, a brain-wiring that evolved much later and in parallel with our increased reliance on social interaction as a means to improve the chances of sending our genes down the line (the drive to reproduce). There is thus a certain irony in the fact that the misnamed “social” media are encouraging a decline in empathy. Your thoughts?
  • Sure you're not confusing narcissism with vanity? If you've ever had the misfortune of having someone with narcissistic personality disorder in your life, you would know it's about more than selfies and seeking constant approval. They are truly sick individuals that destroy the lives of those they claim to love.I would say people's addictions to social media "likes" and posting selfies is vanity
  • Perhaps we need to distinguish between Narcissistic Personality Disorder (NPD) and the adjective "narcissistic." We all know lots of people with way too much self-regard. NPD on the other hand ruins lives and certainly families. People who have NPD are way beyond self centered. They see the world as black and white and all people they interact with become reflections. People with NPD go to extreme lengths to control those around them and will lie, cheat and steal to do that. They are never wrong the other person is always wrong. I have worked for Narcissists and lived with one. Let's not throw around this term without defining it, please.

Who's to blame when fake science gets published? - 1 views

  • The now-discredited study got headlines because it offered hope. It seemed to prove that our sense of empathy, our basic humanity, could overcome prejudice and bridge seemingly irreconcilable differences. It was heartwarming, and it was utter bunkum. The good news is that this particular case of scientific fraud isn't going to do much damage to anyone but the people who concocted and published the study. The bad news is that the alleged deception is a symptom of a weakness at the heart of the scientific establishment.
  • When it was published in Science magazine last December, the research attracted academic as well as media attention; it seemed to provide solid evidence that increasing contact between minority and majority groups could reduce prejudice.
  • But in May, other researchers tried to reproduce the study using the same methods, and failed. Upon closer examination, they uncovered a number of devastating "irregularities" - statistical quirks and troubling patterns - that strongly implied that the whole LaCour/Green study was based upon made-up data.
  • ...6 more annotations...
  • The data hit the fan, at which point Green distanced himself from the survey and called for the Science article to be retracted. The professor even told Retraction Watch, the website that broke the story, that all he'd really done was help LaCour write up the findings.
  • Science magazine didn't shoulder any blame, either. In a statement, editor in chief Marcia McNutt said the magazine was essentially helpless against the depredations of a clever hoaxer: "No peer review process is perfect, and in fact it is very difficult for peer reviewers to detect artful fraud."
  • This is, unfortunately, accurate. In a scientific collaboration, a smart grad student can pull the wool over his adviser's eyes - or vice versa. And if close collaborators aren't going to catch the problem, it's no surprise that outside reviewers dragooned into critiquing the research for a journal won't catch it either. A modern science article rests on a foundation of trust.
  • If the process can't catch such obvious fraud - a hoax the perpetrators probably thought wouldn't work - it's no wonder that so many scientists feel emboldened to sneak a plagiarised passage or two past the gatekeepers.
  • Major peer-review journals tend to accept big, surprising, headline-grabbing results when those are precisely the ones that are most likely to be wrong.
  • Despite the artful passing of the buck by LaCour's senior colleague and the editors of Science magazine, affairs like this are seldom truly the product of a single dishonest grad student. Scientific publishers and veteran scientists - even when they don't take an active part in deception - must recognise that they are ultimately responsible for the culture producing the steady drip-drip-drip of falsification, exaggeration and outright fabrication eroding the discipline they serve.

Here's what the government's dietary guidelines should really say - The Washington Post - 0 views

  • If I were writing the dietary guidelines, I would give them a radical overhaul. I’d go so far as to radically overhaul the way we evaluate diet. Here’s why and how.
  • Lately, as scientists try, and fail, to reproduce results, all of science is taking a hard look at funding biases, statistical shenanigans and groupthink. All that criticism, and then some, applies to nutrition.
  • Prominent in the charge to change the way we do science is John Ioannidis, professor of health research and policy at Stanford University. In 2005, he published “Why Most Research Findings Are False” in the journal PLOS Medicin
  • ...15 more annotations...
  • He came down hard on nutrition in a pull-no-punches 2013 British Medical Journal editorial titled, “Implausible results in human nutrition research,” in which he noted, “Almost every single nutrient imaginable has peer reviewed publications associating it with almost any outcome.”
  • Ioannidis told me that sussing out the connection between diet and health — nutritional epidemiology — is enormously challenging, and “the tools that we’re throwing at the problem are not commensurate with the complexity and difficulty of the problem.” The biggest of those tools is observational research, in which we collect data on what people eat, and track what happens to them.
  • He lists plant-based foods — fruit, veg, whole grains, legumes — but acknowledges that we don’t understand enough to prescribe specific combinations or numbers of servings.
  • funding bias isn’t the only kind. “Fanatical opinions abound in nutrition,” Ioannidis wrote in 2013, and those have bias power too.
  • “Definitive solutions won’t come from another million observational papers or small randomized trials,” reads the subtitle of Ioannidis’s paper. His is a burn-down-the-house ethos.
  • When it comes to actual dietary recommendations, the disagreement is stark. “Ioannidis and others say we have no clue, the science is so bad that we don’t know anything,” Hu told me. “I think that’s completely bogus. We know a lot about the basic elements of a healthy diet.”
  • Give tens of thousands of people that FFQ, and you end up with a ginormous repository of possible correlations. You can zero in on a vitamin, macronutrient or food, and go to town. But not only are you starting with flawed data, you’ve got a zillion possible confounding variables — dietary, demographic, socioeconomic. I’ve heard statisticians call it “noise mining,” and Ioannidis is equally skeptical. “With this type of data, you can get any result you want,” he said. “You can align it to your beliefs.”
  • Big differences in what people eat track with other differences. Heavy plant-eaters are different from, say, heavy meat-eaters in all kinds of ways (income, education, physical activity, BMI). Red meat consumption correlates with increased risk of dying in an accident as much as dying from heart disease. The amount of faith we put in observational studies is a judgment call.
  • I find myself in Ioannidis’s camp. What have we learned, unequivocally enough to build a consensus in the nutrition community, about how diet affects health? Well, trans-fats are bad.
  • Over and over, large population studies get sliced and diced, and it’s all but impossible to figure out what’s signal and what’s noise. Researchers try to do that with controlled trials to test the connections, but those have issues too. They’re expensive, so they’re usually small and short-term. People have trouble sticking to the diet being studied. And scientists are generally looking for what they call “surrogate endpoints,” like increased cholesterol rather than death from heart disease, since it’s impractical to keep a trial going until people die.
  • , what do we do? Hu and Ioannidis actually have similar suggestions. For starters, they both think we should be looking at dietary patterns rather than single foods or nutrients. They also both want to look across the data sets. Ioannidis emphasizes transparency. He wants to open data to the world and analyze all the data sets in the same way to see if “any signals survive.” Hu is more cautious (partly to safeguard confidentiality
  • I have a suggestion. Let’s give up on evidence-based eating. It’s given us nothing but trouble and strife. Our tools can’t find any but the most obvious links between food and health, and we’ve found those already.
  • Instead, let’s acknowledge the uncertainty and eat to hedge against what we don’t know
  • We’ve got two excellent hedges: variety and foods with nutrients intact (which describes such diets as the Mediterranean, touted by researchers). If you severely limit your foods (vegan, keto), you might miss out on something. Ditto if you eat foods with little nutritional value (sugar, refined grains). Oh, and pay attention to the two things we can say with certainty: Keep your weight down, and exercise.
  • I used to say I could tell you everything important about diet in 60 seconds. Over the years, my spiel got shorter and shorter as truisms fell by the wayside, and my confidence waned in a field where we know less, rather than more, over time. I’m down to five seconds now: Eat a wide variety of foods with their nutrients intact, keep your weight down and get some exercise.

Ivy League Schools Are Overrated. Send Your Kids Elsewhere. | New Republic - 1 views

  • a blizzard of admissions jargon that I had to pick up on the fly. “Good rig”: the transcript exhibits a good degree of academic rigor. “Ed level 1”: parents have an educational level no higher than high school, indicating a genuine hardship case. “MUSD”: a musician in the highest category of promise. Kids who had five or six items on their list of extracurriculars—the “brag”—were already in trouble, because that wasn’t nearly enough.
  • With so many accomplished applicants to choose from, we were looking for kids with something special, “PQs”—personal qualities—that were often revealed by the letters or essays. Kids who only had the numbers and the résumé were usually rejected: “no spark,” “not a team-builder,” “this is pretty much in the middle of the fairway for us.” One young person, who had piled up a truly insane quantity of extracurriculars and who submitted nine letters of recommendation, was felt to be “too intense.”
  • On the other hand, the numbers and the résumé were clearly indispensable. I’d been told that successful applicants could either be “well-rounded” or “pointy”—outstanding in one particular way—but if they were pointy, they had to be really pointy: a musician whose audition tape had impressed the music department, a scientist who had won a national award.

  • When I speak of elite education, I mean prestigious institutions like Harvard or Stanford or Williams as well as the larger universe of second-tier selective schools, but I also mean everything that leads up to and away from them—the private and affluent public high schools; the ever-growing industry of tutors and consultants and test-prep courses; the admissions process itself, squatting like a dragon at the entrance to adulthood; the brand-name graduate schools and employment opportunities that come after the B.A.; and the parents and communities, largely upper-middle class, who push their children into the maw of this machine.
  • Our system of elite education manufactures young people who are smart and talented and driven, yes, but also anxious, timid, and lost, with little intellectual curiosity and a stunted sense of purpose: trapped in a bubble of privilege, heading meekly in the same direction, great at what they’re doing but with no idea why they’re doing it.
  • “Super People,” the writer James Atlas has called them—the stereotypical ultra-high-achieving elite college students of today. A double major, a sport, a musical instrument, a couple of foreign languages, service work in distant corners of the globe, a few hobbies thrown in for good measure: They have mastered them all, and with a serene self-assurance
  • Like so many kids today, I went off to college like a sleepwalker. You chose the most prestigious place that let you in; up ahead were vaguely understood objectives: status, wealth—“success.” What it meant to actually get an education and why you might want one—all this was off the table.
  • It was only after 24 years in the Ivy League—college and a Ph.D. at Columbia, ten years on the faculty at Yale—that I started to think about what this system does to kids and how they can escape from it, what it does to our society and how we can dismantle it.
  • I taught many wonderful young people during my years in the Ivy League—bright, thoughtful, creative kids whom it was a pleasure to talk with and learn from. But most of them seemed content to color within the lines that their education had marked out for them. Very few were passionate about ideas. Very few saw college as part of a larger project of intellectual discovery and development. Everyone dressed as if they were ready to be interviewed at a moment’s notice.
  • Look beneath the façade of seamless well-adjustment, and what you often find are toxic levels of fear, anxiety, and depression, of emptiness and aimlessness and isolation. A large-scale survey of college freshmen recently found that self-reports of emotional well-being have fallen to their lowest level in the study’s 25-year history.
  • So extreme are the admission standards now that kids who manage to get into elite colleges have, by definition, never experienced anything but success. The prospect of not being successful terrifies them, disorients them. The cost of falling short, even temporarily, becomes not merely practical, but existential. The result is a violent aversion to risk.
  • There are exceptions, kids who insist, against all odds, on trying to get a real education. But their experience tends to make them feel like freaks. One student told me that a friend of hers had left Yale because she found the school “stifling to the parts of yourself that you’d call a soul.”
  • What no one seems to ask is what the “return” is supposed to be. Is it just about earning more money? Is the only purpose of an education to enable you to get a job? What, in short, is college for?
  • The first thing that college is for is to teach you to think.
  • College is an opportunity to stand outside the world for a few years, between the orthodoxy of your family and the exigencies of career, and contemplate things from a distance.
  • it is only through the act of establishing communication between the mind and the heart, the mind and experience, that you become an individual, a unique being—a soul. The job of college is to assist you to begin to do that. Books, ideas, works of art and thought, the pressure of the minds around you that are looking for their own answers in their own ways.
  • College is not the only chance to learn to think, but it is the best. One thing is certain: If you haven’t started by the time you finish your B.A., there’s little likelihood you’ll do it later. That is why an undergraduate experience devoted exclusively to career preparation is four years largely wasted.
  • Elite schools like to boast that they teach their students how to think, but all they mean is that they train them in the analytic and rhetorical skills that are necessary for success in business and the professions.
  • Everything is technocratic—the development of expertise—and everything is ultimately justified in technocratic terms.
  • Religious colleges—even obscure, regional schools that no one has ever heard of on the coasts—often do a much better job in that respect.
  • At least the classes at elite schools are academically rigorous, demanding on their own terms, no? Not necessarily. In the sciences, usually; in other disciplines, not so much
  • professors and students have largely entered into what one observer called a “nonaggression pact.”
  • higher marks for shoddier work.
  • today’s young people appear to be more socially engaged than kids have been for several decades and that they are more apt to harbor creative or entrepreneurial impulses
  • they tend to be played out within the same narrow conception of what constitutes a valid life: affluence, credentials, prestige.
  • Experience itself has been reduced to instrumental function, via the college essay. From learning to commodify your experiences for the application, the next step has been to seek out experiences in order to have them to commodify
  • there is now a thriving sector devoted to producing essay-ready summers
  • To be a high-achieving student is to constantly be urged to think of yourself as a future leader of society.
  • what these institutions mean by leadership is nothing more than getting to the top. Making partner at a major law firm or becoming a chief executive, climbing the greasy pole of whatever hierarchy you decide to attach yourself to. I don’t think it occurs to the people in charge of elite colleges that the concept of leadership ought to have a higher meaning, or, really, any meaning.
  • The irony is that elite students are told that they can be whatever they want, but most of them end up choosing to be one of a few very similar things
  • As of 2010, about a third of graduates went into financing or consulting at a number of top schools, including Harvard, Princeton, and Cornell.
  • Whole fields have disappeared from view: the clergy, the military, electoral politics, even academia itself, for the most part, including basic science
  • It’s considered glamorous to drop out of a selective college if you want to become the next Mark Zuckerberg, but ludicrous to stay in to become a social worker. “What Wall Street figured out,” as Ezra Klein has put it, “is that colleges are producing a large number of very smart, completely confused graduates. Kids who have ample mental horsepower, an incredible work ethic and no idea what to do next.”
  • t almost feels ridiculous to have to insist that colleges like Harvard are bastions of privilege, where the rich send their children to learn to walk, talk, and think like the rich. Don’t we already know this? They aren’t called elite colleges for nothing. But apparently we like pretending otherwise. We live in a meritocracy, after all.
  • Visit any elite campus across our great nation, and you can thrill to the heart-warming spectacle of the children of white businesspeople and professionals studying and playing alongside the children of black, Asian, and Latino businesspeople and professionals
  • That doesn’t mean there aren’t a few exceptions, but that is all they are. In fact, the group that is most disadvantaged by our current admissions policies are working-class and rural whites, who are hardly present
  • The college admissions game is not primarily about the lower and middle classes seeking to rise, or even about the upper-middle class attempting to maintain its position. It is about determining the exact hierarchy of status within the upper-middle class itself.
  • This system is exacerbating inequality, retarding social mobility, perpetuating privilege, and creating an elite that is isolated from the society that it’s supposed to lead. The numbers are undeniable. In 1985, 46 percent of incoming freshmen at the 250 most selective colleges came from the top quarter of the income distribution. By 2000, it was 55 percent
  • The major reason for the trend is clear. Not increasing tuition, though that is a factor, but the ever-growing cost of manufacturing children who are fit to compete in the college admissions game
  • Wealthy families start buying their children’s way into elite colleges almost from the moment they are born: music lessons, sports equipment, foreign travel (“enrichment” programs, to use the all-too-perfect term)—most important, of course, private-school tuition or the costs of living in a place with top-tier public schools.
  • s there anything that I can do, a lot of young people have written to ask me, to avoid becoming an out-of-touch, entitled little shit? I don’t have a satisfying answer, short of telling them to transfer to a public university. You cannot cogitate your way to sympathy with people of different backgrounds, still less to knowledge of them. You need to interact with them directly, and it has to be on an equal footing
  • Elite private colleges will never allow their students’ economic profile to mirror that of society as a whole. They can’t afford to—they need a critical mass of full payers and they need to tend to their donor base—and it’s not even clear that they’d want to.
  • Elite colleges are not just powerless to reverse the movement toward a more unequal society; their policies actively promote it.
  • The SAT is supposed to measure aptitude, but what it actually measures is parental income, which it tracks quite closely
  • U.S. News and World Report supplies the percentage of freshmen at each college who finished in the highest 10 percent of their high school class. Among the top 20 universities, the number is usually above 90 percent. I’d be wary of attending schools like that. Students determine the level of classroom discussion; they shape your values and expectations, for good and ill. It’s partly because of the students that I’d warn kids away from the Ivies and their ilk. Kids at less prestigious schools are apt to be more interesting, more curious, more open, and far less entitled and competitive.
  • The best option of all may be the second-tier—not second-rate—colleges, like Reed, Kenyon, Wesleyan, Sewanee, Mount Holyoke, and others. Instead of trying to compete with Harvard and Yale, these schools have retained their allegiance to real educational values.
  • Not being an entitled little shit is an admirable goal. But in the end, the deeper issue is the situation that makes it so hard to be anything else. The time has come, not simply to reform that system top to bottom, but to plot our exit to another kind of society altogether.
  • The education system has to act to mitigate the class system, not reproduce it. Affirmative action should be based on class instead of race, a change that many have been advocating for years. Preferences for legacies and athletes ought to be discarded. SAT scores should be weighted to account for socioeconomic factors. Colleges should put an end to résumé-stuffing by imposing a limit on the number of extracurriculars that kids can list on their applications. They ought to place more value on the kind of service jobs that lower-income students often take in high school and that high achievers almost never do. They should refuse to be impressed by any opportunity that was enabled by parental wealth
  • More broadly, they need to rethink their conception of merit. If schools are going to train a better class of leaders than the ones we have today, they’re going to have to ask themselves what kinds of qualities they need to promote. Selecting students by GPA or the number of extracurriculars more often benefits the faithful drudge than the original mind.
  • reforming the admissions process. That might address the problem of mediocrity, but it won’t address the greater one of inequality
  • The problem is the Ivy League itself. We have contracted the training of our leadership class to a set of private institutions. However much they claim to act for the common good, they will always place their interests first.
  • I’ve come to see that what we really need is to create one where you don’t have to go to the Ivy League, or any private college, to get a first-rate education.
  • High-quality public education, financed with public money, for the benefit of all
  • Everybody gets an equal chance to go as far as their hard work and talent will take them—you know, the American dream. Everyone who wants it gets to have the kind of mind-expanding, soul-enriching experience that a liberal arts education provides.
  • We recognize that free, quality K–12 education is a right of citizenship. We also need to recognize—as we once did and as many countries still do—that the same is true of higher education. We have tried aristocracy. We have tried meritocracy. Now it’s time to try democracy.

Is our world a simulation? Why some scientists say it's more likely than not | Technolo... - 3 views

  • Musk is just one of the people in Silicon Valley to take a keen interest in the “simulation hypothesis”, which argues that what we experience as reality is actually a giant computer simulation created by a more sophisticated intelligence
  • Oxford University’s Nick Bostrom in 2003 (although the idea dates back as far as the 17th-century philosopher René Descartes). In a paper titled “Are You Living In a Simulation?”, Bostrom suggested that members of an advanced “posthuman” civilization with vast computing power might choose to run simulations of their ancestors in the universe.
  • If we believe that there is nothing supernatural about what causes consciousness and it’s merely the product of a very complex architecture in the human brain, we’ll be able to reproduce it. “Soon there will be nothing technical standing in the way to making machines that have their own consciousness,
  • ...14 more annotations...
  • At the same time, videogames are becoming more and more sophisticated and in the future we’ll be able to have simulations of conscious entities inside them.
  • “Forty years ago we had Pong – two rectangles and a dot. That’s where we were. Now 40 years later, we have photorealistic, 3D simulations with millions of people playing simultaneously and it’s getting better every year. And soon we’ll have virtual reality, we’ll have augmented reality,” said Musk. “If you assume any rate of improvement at all, then the games will become indistinguishable from reality.”
  • “If one progresses at the current rate of technology a few decades into the future, very quickly we will be a society where there are artificial entities living in simulations that are much more abundant than human beings.
  • If there are many more simulated minds than organic ones, then the chances of us being among the real minds starts to look more and more unlikely. As Terrile puts it: “If in the future there are more digital people living in simulated environments than there are today, then what is to say we are not part of that already?”
  • Reasons to believe that the universe is a simulation include the fact that it behaves mathematically and is broken up into pieces (subatomic particles) like a pixelated video game. “Even things that we think of as continuous – time, energy, space, volume – all have a finite limit to their size. If that’s the case, then our universe is both computable and finite. Those properties allow the universe to be simulated,” Terrile said
  • “Is it logically possible that we are in a simulation? Yes. Are we probably in a simulation? I would say no,” said Max Tegmark, a professor of physics at MIT.
  • “In order to make the argument in the first place, we need to know what the fundamental laws of physics are where the simulations are being made. And if we are in a simulation then we have no clue what the laws of physics are. What I teach at MIT would be the simulated laws of physics,”
  • Terrile believes that recognizing that we are probably living in a simulation is as game-changing as Copernicus realizing that the Earth was not the center of the universe. “It was such a profound idea that it wasn’t even thought of as an assumption,”
  • That we might be in a simulation is, Terrile argues, a simpler explanation for our existence than the idea that we are the first generation to rise up from primordial ooze and evolve into molecules, biology and eventually intelligence and self-awareness. The simulation hypothesis also accounts for peculiarities in quantum mechanics, particularly the measurement problem, whereby things only become defined when they are observed.
  • “For decades it’s been a problem. Scientists have bent over backwards to eliminate the idea that we need a conscious observer. Maybe the real solution is you do need a conscious entity like a conscious player of a video game,
  • How can the hypothesis be put to the test
  • scientists can look for hallmarks of simulation. “Suppose someone is simulating our universe – it would be very tempting to cut corners in ways that makes the simulation cheaper to run. You could look for evidence of that in an experiment,” said Tegmark
  • First, it provides a scientific basis for some kind of afterlife or larger domain of reality above our world. “You don’t need a miracle, faith or anything special to believe it. It comes naturally out of the laws of physics,”
  • it means we will soon have the same ability to create our own simulations. “We will have the power of mind and matter to be able to create whatever we want and occupy those worlds.”

Five months on, what scientists now know about the coronavirus | World news | The Guardian - 0 views

  • The Sars-CoV-2 virus almost certainly originated in bats, which have evolved fierce immune responses to viruses, researchers have discovered. These defences drive viruses to replicate faster so that they can get past bats’ immune defences. In turn, that transforms the bat into a reservoir of rapidly reproducing and highly transmissible viruses
  • “This virus probably jumped from a bat into another animal, and that other animal was probably near a human, maybe in a market,
  • Virus-ridden particles are inhaled by others and come into contact with cells lining the throat and larynx. These cells have large numbers of receptors – known as Ace-2 receptors – on their surfaces. (Cell receptors play a key role in passing chemicals into cells and in triggering signals between cells.
  • ...19 more annotations...
  • “This virus has a surface protein that is primed to lock on that receptor and slip its RNA into the cell,”
  • Once inside, that RNA inserts itself into the cell’s own replication machinery and makes multiple copies of the virus. These burst out of the cell, and the infection spreads. Antibodies generated by the body’s immune system eventually target the virus and in most cases halt its progress.
  • “A Covid-19 infection is generally mild, and that really is the secret of the virus’s success,” adds Ball. “Many people don’t even notice they have got an infection and so go around their work, homes and supermarkets infecting others.”
  • the virus can cause severe problems. This happens when it moves down the respiratory tract and infects the lungs, which are even richer in cells with Ace-2 receptors. Many of these cells are destroyed, and lungs become congested with bits of broken cell. In these cases, patients will require treatment in intensive care.
  • Even worse, in some cases, a person’s immune system goes into overdrive, attracting cells to the lungs in order to attack the virus, resulting in inflammation
  • This process can run out of control, more immune cells pour in, and the inflammation gets worse. This is known as a cytokine storm.
  • Just why cytokine storms occur in some patients but not in the vast majority is unclear
  • Doctors examining patients recovering from a Covid-19 infection are finding fairly high levels of neutralising antibodies in their blood. These antibodies are made by the immune system, and they coat an invading virus at specific points, blocking its ability to break into cells.

  • “It is clear that immune responses are being mounted against Covid-19 in infected people,” says virologist Mike Skinner of Imperial College London. “And the antibodies created by that response will provide protection against future infections – but we should note that it is unlikely this protection will be for life.”
  • “That means that even if most people do eventually become exposed to the virus, it is still likely to become endemic – which means we would see seasonal peaks of infection of this disease. We will have reached a steady state with regard to Covid-19.”
  • Skinner is doubtful. “We have got to consider this pandemic from the virus’s position,” he says. “It is spreading round the world very nicely. It is doing OK. Change brings it no benefit.”
  • In the end, it will be the development and roll-out of an effective vaccine that will free us from the threat of Covid-19,
  • the journal Nature reported that 78 vaccine projects had been launched round the globe – with a further 37 in development.
  • vaccines require large-scale safety and efficacy studies. Thousands of people would receive either the vaccine itself or a placebo to determine if the former were effective at preventing infection from the virus which they would have encountered naturally. That, inevitably, is a lengthy process.
  • some scientists have proposed a way to speed up the process – by deliberately exposing volunteers to the virus to determine a vaccine’s efficacy.
  • Volunteers would have to be young and healthy, he stresses: “Their health would also be closely monitored, and they would have access to intensive care and any available medicines.”
  • The result could be a vaccine that would save millions of lives by being ready for use in a much shorter time than one that went through standard phase three trials.
  • phase-three trials are still some way off, so we have time to consider the idea carefully.”

Opinion | The Atlanta Shootings and a Religious Toxicity - The New York Times - 0 views

  • I’m a Scholar of Religion. Here’s What I See in the Atlanta Shootings.
  • Did racism or theology or gender motivate the shootings in Georgia? All of the above.
  • I saw in Korean sources first that six of the dead were Asian women, four of Korean descent
  • ...28 more annotations...
  • I didn’t yet know their names; I mourned them as Daughter, Big Sister, Mother, Aunt.
  • As a child I asked my parents why we did this. They explained that who we are is inseparable from who loves us and whom we love.
  • Who are you? Where are you from? What do you believe? To move through this world as an Asian who is American is to exist under the gaze of white supremacy.
  • In other words, we have to constantly give an accounting of ourselves to justify and explain why we are here.
  • I walked through the world in a kind of haze of anger and despair.
  • So we learned early on the name of the alleged murderer.
  • Was it racism? Was it deep-rooted misogyny? Was it a fetishization of Asian women in particular? Was it toxic theology — an extreme fear of God and an equally extreme self-loathing?
  • Race, gender, religion and culture are all implicated
  • The Asian who is American is an accessory — the one you want for your group projects, or the one who makes your farms yield more.
  • And the Asian woman who is American is simultaneously translucent, a mirror and a looking glass; she is a ghost, invisible, unknowable, stripped of her identity, making her both desirable and expendable. How else to explain how easily she is attacked?
  • We learned that he is white. We learned that he is a Southern Baptist, but not his motivation.
  • All the moments I’d kept hidden for years suddenly rushed to the surface: the attacks, the looks, the vandalism, the endless stream of questions
  • The long history of anti-Asian racism is rooted in the history of American expansionism amid wide-ranging legal, cultural and military projects across the Pacific.
  • These colonial projects hypersexualized Asian women, through forced sex and sex work, casting them as docile creatures that brought comfort
  • They also shaped Asian men as submissive and feminine, objects to be conquered, dominated and consumed.
  • Even the humanitarian interventions and the religious outreach that helped to shape much of white imagination about Asian women’s bodies overseas were then continuously reproduced here in America.
  • But churches are imperfect, man-made institutions, burdened by ego and fear
  • I grew up never seeing a woman preach from the pulpit.
  • Later I discovered stories that centered on people on the margins — Black, queer, women and others.
  • These theologies radicalized my faith; I saw myriad possibilities of God in the world.
  • When I looked in the mirror, I saw the divine in myself and in the faces of those around me. This changed everything. The God of grace I proclaim from the pulpit lives in us, loves every single one of us, and this was liberation.
  • But fear is not so easily uprooted, and shame is not limited to one culture or religion.
  • Absolute moral ideals of virginity or marital sex have long been linked to conservative white Christian attempts at what is sometimes called “sexual containment” or more popularly known as purity culture.
  • Though more and more people of faith have questioned the psychological impact of purity culture, shame around sex persists.
  • The Asian women murdered in Atlanta were an explicit threat to the purported ideal; their perceived entanglement with sex work justified this violence.
  • “I just don’t see you as Asian.” Proximity to whiteness is seen as our saving grace, but we are still dying.

A Single Fire Killed At Least 10% Of The World's Giant Sequoias, Study Says : NPR - 2 views

  • At least a tenth of the world's mature giant sequoia trees were destroyed by a single California wildfire that tore through the southern Sierra Nevada last year,
  • a copy of the report that describes catastrophic destruction from the Castle Fire, which charred 273 square miles (707 square km) of timber in Sequoia National Park.
  • Researchers used satellite imagery and modeling from previous fires to determine that between 7,500 and 10,000 of the towering species perished in the fire. That equates to 10% to 14% of the world's mature giant sequoia population, the newspaper said.

  • These trees have lived for thousands of years. They've survived dozens of wildfires already,"
  • The consequences of losing large numbers of giant sequoias could be felt for decades, forest managers said.
  • Redwood and sequoia forests are among the world's most efficient at removing and storing carbon dioxide in the atmosphere.
  • "I have a vain hope that once we get out on the ground the situation won't be as bad, but that's hope — that's not science," she said.
  • The newspaper said the extent of the damage to one of the world's most treasured trees is noteworthy because the sequoias themselves are incredibly well adapted to fire.
  • The old-growth trees — some of which are more than 2,000 years old and 250 feet (76 meters) tall — require fire to burst their pine cones and reproduce.
  • Brigham estimates that the park will need to burn around 30 times that number to get the forest back to a healthy state.
  •  
    Wildfires destroy forests all the time, what surprised me the most about this article was the fact that between 7,500 and 10,000 of the towering species perished in the fire that is just mind-blowing to me.
