The Two Contradictory Ideas Many Americans Have About the Economy - The Atlantic - 0 views

  • How do people reconcile a belief in individual autonomy with nationwide wage stagnation?
  • “Many middle-class wage earners are victims of the economy, and, perhaps, of that great, glowing, irresistible American promise that has been drummed into our heads since birth: Just work hard and you can have it all.”
  • This sentiment taunts at two sacred and quintessentially American convictions—that success is self-determined and that advancement is inevitable for anyone with a serious work ethic. According to a 2014 Pew Global Attitudes Study, people in the United States are much more likely to hold these two beliefs than many of their European counterparts.

  • Many Americans, then, are holding two contradictory ideas in their mind at once: the optimistic belief that their success is in their hands (on display since Tocqueville’s Democracy in America) and the acknowledgement that wages have been steadily stagnating (on decline since the band America).
  • In his story, Gabler concedes that, no matter how illogical and uninformed his financial decisions might have been, he remained seduced by a superseding assumption that he “would always overcome any adversity, should it arrive.”
  • “This is the genius and the Achilles’ heel of American culture,” Newman says. “We do have a strong belief in self-determination and agency, even when our expectations fly in the face of reality.”
  • Struggling white-collar workers and managers, she says, especially stood out in her research for how likely they were to believe they were the authors of their own fate. “And if your destiny isn’t working out very well,” she says, “you only have yourself to blame,” in their telling.
  • part of what makes financial fragility so distressing in the United States is that citizens aren’t afforded the regimen of protections offered by Europe’s wealthier governments.
  • “These are social democracies that come to the rescue of people in trouble or are just more generous even if they’re not in trouble,” says Newman. “So the kind of suffering that will happen in a society like that is not one of material deprivation nearly as much as what we call in the trade ‘social exclusion.’”

The Stereotypes About Math That Hold Americans Back - Jo Boaler - The Atlantic - 2 views

  • Mathematics education in the United States is broken. Open any newspaper and stories of math failure shout from the pages: low international rankings, widespread innumeracy in the general population, declines in math majors. Here’s the most shocking statistic I have read in recent years: 60 percent of the 13 million two-year college students in the U.S. are currently placed into remedial math courses; 75 percent of them fail or drop the courses and leave college with no degree.
  • We need to change the way we teach math in the U.S., and it is for this reason that I support the move to Common Core mathematics.
  • One of the reasons for these results is that mathematical problems that need thought, connection making, and even creativity are more engaging for students of all levels and for students of different genders, races, and socio-economic groups. This is not only shown by my research but by decades of research in our field.

  • ways of working are critical in mathematical work and when they are taught and valued, many more students contribute, leading to higher achievement
  • mathematics education we suffer from the widespread, distinctly American idea that only some people can be “math people.” This idea has been disproved by scientific research showing the incredible potential of the brain to grow and adapt. But the idea that math is hard, uninteresting, and accessible only to “nerds” persists. 
  • harsh stereotypical thinking—mathematics is for select racial groups and men. This thinking, as well as the teaching practices that go with it, have provided the perfect conditions for the creation of a math underclass.
  • There is a good reason for this: Justification and reasoning are two of the acts that lie at the heart of mathematics. They are, in many ways, the essence of what mathematics is.  Scientists work to prove or disprove new theories by finding many cases that work or counter-examples that do not. Mathematicians, by contrast prove the validity of their propositions through justification and reasoning.
  • does not simply test a mathematical definition, as the first does. It requires that students visualize a triangle, use transformational geometry, consider whether different cases satisfy the mathematical definition, and then justify their thinking.
  • online platform explaining research evidence on ability and the brain and on good mathematics teaching, for teachers and parents. The course had a transformative effect. It was taken by 40,000 people, and 95 percent said they would change their teaching or parenting as a result.
  • The young people who are successful in today’s workforce are those who can discuss and reason about productive mathematical pathways, and who can be wrong, but can trace back to errors and work to correct them.
  • American idea that those who are good at math are those who are fast. Speed is revered in math classes across the U.S., and students as young as five years old are given timed tests—even though these have been shown to create math anxiety in young children. Parents use flash cards and other devices to promote speed, not knowing that they are probably damaging their children’s mathematical development
  • The fact of being quick or slow isn't really relevant
  • gives more time for depth and exploration than the curricula it has replaced by removing some of the redundant methods students will never need or use.

What's at Stake in a Health Bill That Slashes the Safety Net - The New York Times - 0 views

  • It is startling to realize just how much the social safety net expanded during Barack Obama’s presidency. In 2016, means-tested entitlements like Medicaid and food stamps absorbed 3.8 percent of the nation’s gross domestic product, almost a full percentage point more than in 2008
  • Public social spending writ large — including health care, pensions, unemployment insurance, poverty alleviation and the like — reached 19.3 percent of G.D.P.
  • Government in the United States still spends less than most of its peers across the industrialized world to support the general welfare of its citizens.

  • Last week, President Trump’s sketch of a budget underscored how little interest he has in the nation’s social insurance programs — proposing to shift $54 billion next year to the military
  • Republicans in the House plan to vote this week to undo the Affordable Care Act. That law was Mr. Obama’s singular contribution toward an American welfare state, the biggest expansion of the nation’s safety net in half a century.
  • Welfare reform did hurt many poor people by converting antipoverty funds into block grants to the states. But it was accompanied by a big increase in the earned-income tax credit, the nation’s most effective antipoverty tool today.
  • “No other Congress or administration has ever put forward a plan with the intention of having fewer people covered.”
  • Who knows where this retrenchment takes the country? Maybe attaching a work requirement to Medicaid, as conservatives propose, will prod the poor to get a job. Or perhaps it will just cut more people from Medicaid’s rolls. Further up the income ladder, losing a job will become more costly when it means losing health insurance, too.
  • Millions of Americans — poor ones, mainly — will use much less health care. They will make fewer outpatient visits, have fewer mammograms and cholesterol checks.
  • In any event, public health insurance will take a big hit.
  • Under the House Republican plan, 24 million more Americans will lack health insurance by 2026, according to the nonpartisan Congressional Budget Office.
  • Might depression and mental health problems destabilize families, feeding down into the health, education and well-being of the next generation?
  • Yet it is worth remembering that among advanced nations, the United States is a laggard in life expectancy and has one of the highest infant mortality rates.
  • If American history provides any sort of guidance, it is that continuing to shred the social safety net will definitely make things worse.
  •  
    Directing spending away from American people and their access to healthcare is a definite possibility for Trump. It will be interesting to see the effect this has on the healthcare market and the American people. This article says it will probably hurt many poor people and decrease their health.

Clouds' Effect on Climate Change Is Last Bastion for Dissenters - NYTimes.com - 0 views

  • For decades, a small group of scientific dissenters has been trying to shoot holes in the prevailing science of climate change, offering one reason after another why the outlook simply must be wrong.

Go to Blog » Readers’ Comments "There is always some possibility that the scientific consensus may be wrong and Dr. Lindzen may be right, or that both may be wrong. But the worst possible place to resolve such issues is the political arena." Alexander Flax, Potomac, MD Read Full Comment » Post a Comment » Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97 percent of working climate scientists now see global warming as a serious risk.
  • They acknowledge that the human release of greenhouse gases will cause the planet to warm. But they assert that clouds — which can either warm or cool the earth, depending on the type and location — will shift in such a way as to counter much of the expected temperature rise and preserve the equable climate on which civilization depends.
  • At gatherings of climate change skeptics on both sides of the Atlantic, Dr. Lindzen has been treated as a star. During a debate in Australia over carbon taxes, his work was cited repeatedly. When he appears at conferences of the Heartland Institute, the primary American organization pushing climate change skepticism, he is greeted by thunderous applause.
  • ...13 more annotations...
  • His idea has drawn withering criticism from other scientists, who cite errors in his papers and say proof is lacking. Enough evidence is already in hand, they say, to rule out the powerful cooling effect from clouds that would be needed to offset the increase of greenhouse gases.
  • “If you listen to the credible climate skeptics, they’ve really pushed all their chips onto clouds.”
  • Dr. Lindzen is “feeding upon an audience that wants to hear a certain message, and wants to hear it put forth by people with enough scientific reputation that it can be sustained for a while, even if it’s wrong science,” said Christopher S. Bretherton, an atmospheric researcher at the University of Washington. “I don’t think it’s intellectually honest at all.”
  • With climate policy nearly paralyzed in the United States, many other governments have also declined to take action, and worldwide emissions of greenhouse gases are soaring.
  • The most elaborate computer programs have agreed on a broad conclusion: clouds are not likely to change enough to offset the bulk of the human-caused warming. Some of the analyses predict that clouds could actually amplify the warming trend sharply through several mechanisms, including a reduction of some of the low clouds that reflect a lot of sunlight back to space. Other computer analyses foresee a largely neutral effect. The result is a big spread in forecasts of future temperature, one that scientists have not been able to narrow much in 30 years of effort.
  • The earth’s surface has already warmed about 1.4 degrees Fahrenheit since the Industrial Revolution, most of that in the last 40 years. Modest as it sounds, it is an average for the whole planet, representing an enormous addition of heat. An even larger amount is being absorbed by the oceans. The increase has caused some of the world’s land ice to melt and the oceans to rise.
  • Even in the low projection, many scientists say, the damage could be substantial. In the high projection, some polar regions could heat up by 20 or 25 degrees Fahrenheit — more than enough, over centuries or longer, to melt the Greenland ice sheet, raising sea level by a catastrophic 20 feet or more. Vast changes in  rainfall, heat waves and other weather patterns would most likely accompany such a large warming. “The big damages come if the climate sensitivity to greenhouse gases turns out to be high,” said Raymond T. Pierrehumbert, a climate scientist at the University of Chicago. “Then it’s not a bullet headed at us, but a thermonuclear warhead.”
  • But the problem of how clouds will behave in a future climate is not yet solved — making the unheralded field of cloud research one of the most important pursuits of modern science.
  • for more than a decade, Dr. Lindzen has said that when surface temperature increases, the columns of moist air rising in the tropics will rain out more of their moisture, leaving less available to be thrown off as ice, which forms the thin, high clouds known as cirrus. Just like greenhouse gases, these cirrus clouds act to reduce the cooling of the earth, and a decrease of them would counteract the increase of greenhouse gases. Dr. Lindzen calls his mechanism the iris effect, after the iris of the eye, which opens at night to let in more light. In this case, the earth’s “iris” of high clouds would be opening to let more heat escape.
  • Dr. Lindzen acknowledged that the 2009 paper contained “some stupid mistakes” in his handling of the satellite data. “It was just embarrassing,” he said in an interview. “The technical details of satellite measurements are really sort of grotesque.” Last year, he tried offering more evidence for his case, but after reviewers for a prestigious American journal criticized the paper, Dr. Lindzen published it in a little-known Korean journal. Dr. Lindzen blames groupthink among climate scientists for his publication difficulties, saying the majority is determined to suppress any dissenting views. They, in turn, contend that he routinely misrepresents the work of other researchers.
  • Ultimately, as the climate continues warming and more data accumulate, it will become obvious how clouds are reacting. But that could take decades, scientists say, and if the answer turns out to be that catastrophe looms, it would most likely be too late. By then, they say, the atmosphere would contain so much carbon dioxide as to make a substantial warming inevitable, and the gas would not return to a normal level for thousands of years.
  • In his Congressional appearances, speeches and popular writings, Dr. Lindzen offers little hint of how thin the published science supporting his position is. Instead, starting from his disputed iris mechanism, he makes what many of his colleagues see as an unwarranted leap of logic, professing near-certainty that climate change is not a problem society needs to worry about.
  • “Even if there were no political implications, it just seems deeply unprofessional and irresponsible to look at this and say, ‘We’re sure it’s not a problem,’ ” said Kerry A. Emanuel, another M.I.T. scientist. “It’s a special kind of risk, because it’s a risk to the collective civilization.”

Why It's OK to Let Apps Make You a Better Person - Evan Selinger - Technology - The Atlantic - 0 views

  • one theme emerges from the media coverage of people's relationships with our current set of technologies: Consumers want digital willpower. App designers in touch with the latest trends in behavioral modification--nudging, the quantified self, and gamification--and good old-fashioned financial incentive manipulation, are tackling weakness of will. They're harnessing the power of payouts, cognitive biases, social networking, and biofeedback. The quantified self becomes the programmable self.
  • the trend still has multiple interesting dimensions
  • Individuals are turning ever more aspects of their lives into managerial problems that require technological solutions. We have access to an ever-increasing array of free and inexpensive technologies that harness incredible computational power that effectively allows us to self-police behavior everywhere we go. As pervasiveness expands, so does trust.

  • Some embrace networked, data-driven lives and are comfortable volunteering embarrassing, real time information about what we're doing, whom we're doing it with, and how we feel about our monitored activities.
  • Put it all together and we can see that our conception of what it means to be human has become "design space." We're now Humanity 2.0, primed for optimization through commercial upgrades. And today's apps are more harbinger than endpoint.
  • philosophers have had much to say about the enticing and seemingly inevitable dispersion of technological mental prosthetic that promise to substitute or enhance some of our motivational powers.
  • beyond the practical issues lie a constellation of central ethical concerns.
  • they should cause us to pause as we think about a possible future that significantly increases the scale and effectiveness of willpower-enhancing apps. Let's call this hypothetical future Digital Willpower World and characterize the ethical traps we're about to discuss as potential general pitfalls
  • it is antithetical to the ideal of " resolute choice." Some may find the norm overly perfectionist, Spartan, or puritanical. However, it is not uncommon for folks to defend the idea that mature adults should strive to develop internal willpower strong enough to avoid external temptations, whatever they are, and wherever they are encountered.
  • In part, resolute choosing is prized out of concern for consistency, as some worry that lapse of willpower in any context indicates a generally weak character.
  • Fragmented selves behave one way while under the influence of digital willpower, but another when making decisions without such assistance. In these instances, inconsistent preferences are exhibited and we risk underestimating the extent of our technological dependency.
  • It simply means that when it comes to digital willpower, we should be on our guard to avoid confusing situational with integrated behaviors.
  • the problem of inauthenticity, a staple of the neuroethics debates, might arise. People might start asking themselves: Has the problem of fragmentation gone away only because devices are choreographing our behavior so powerfully that we are no longer in touch with our so-called real selves -- the selves who used to exist before Digital Willpower World was formed?
  • Infantalized subjects are morally lazy, quick to have others take responsibility for their welfare. They do not view the capacity to assume personal responsibility for selecting means and ends as a fundamental life goal that validates the effort required to remain committed to the ongoing project of maintaining willpower and self-control.
  • Michael Sandel's Atlantic essay, "The Case Against Perfection." He notes that technological enhancement can diminish people's sense of achievement when their accomplishments become attributable to human-technology systems and not an individual's use of human agency.
  • Borgmann worries that this environment, which habituates us to be on auto-pilot and delegate deliberation, threatens to harm the powers of reason, the most central component of willpower (according to the rationalist tradition).
  • In several books, including Technology and the Character of Contemporary Life, he expresses concern about technologies that seem to enhance willpower but only do so through distraction. Borgmann's paradigmatic example of the non-distracted, focally centered person is a serious runner. This person finds the practice of running maximally fulfilling, replete with the rewarding "flow" that can only comes when mind/body and means/ends are unified, while skill gets pushed to the limit.
  • Perhaps the very conception of a resolute self was flawed. What if, as psychologist Roy Baumeister suggests, willpower is more "staple of folk psychology" than real way of thinking about our brain processes?
  • novel approaches suggest the will is a flexible mesh of different capacities and cognitive mechanisms that can expand and contract, depending on the agent's particular setting and needs. Contrary to the traditional view that identifies the unified and cognitively transparent self as the source of willed actions, the new picture embraces a rather diffused, extended, and opaque self who is often guided by irrational trains of thought. What actually keeps the self and its will together are the given boundaries offered by biology, a coherent self narrative created by shared memories and experiences, and society. If this view of the will as an expa
  • nding and contracting system with porous and dynamic boundaries is correct, then it might seem that the new motivating technologies and devices can only increase our reach and further empower our willing selves.
  • "It's a mistake to think of the will as some interior faculty that belongs to an individual--the thing that pushes the motor control processes that cause my action," Gallagher says. "Rather, the will is both embodied and embedded: social and physical environment enhance or impoverish our ability to decide and carry out our intentions; often our intentions themselves are shaped by social and physical aspects of the environment."
  • It makes perfect sense to think of the will as something that can be supported or assisted by technology. Technologies, like environments and institutions can facilitate action or block it. Imagine I have the inclination to go to a concert. If I can get my ticket by pressing some buttons on my iPhone, I find myself going to the concert. If I have to fill out an application form and carry it to a location several miles away and wait in line to pick up my ticket, then forget it.
  • Perhaps the best way forward is to put a digital spin on the Socratic dictum of knowing myself and submit to the new freedom: the freedom of consuming digital willpower to guide me past the sirens.

Do People Eat Too Much Because They Enjoy It Too Little? - Hit & Run : Reason Magazine - 0 views

  • Qnexa, which in clinical trials helped subjects lose about one-tenth of their weight on average, combines an appetite-suppressing stimulant with "an anticonvulsant shown to reduce cravings for binge-eaters." Lehrer says it seems to work partly by increasing "activity in the dopamine reward pathway," which "allows dieters to squeeze more satisfaction from every bite."
  • "People crave pleasure, and they don't stop until they get their fill, even if means consuming the entire pint of Häagen-Dazs." He says one lesson for dieters is that "it's important to seek pleasure from many sources," since "people quickly adapt to the pleasure of any single food." 
  • it contradicts the advice commonly heard from anti-obesity crusaders such as Kelly Brownell and David Kessler, who say the problem is that food is too delicious and too varied. Rats who eat their fill of one food, they note, will begin chowing down again if given something different. Hence variety is the dieter's enemy—not, as Lehrer suggests, his friend.

When that happens, they won't just put individuals out of work temporarily. Entire classes of workers will be out of work permanently. In other words, the Luddites weren't wrong. They were just 200 years too early
  • Slowly but steadily, labor's share of total national income has gone down, while the share going to capital owners has gone up. The most obvious effect of this is the skyrocketing wealth of the top 1 percent, due mostly to huge increases in capital gains and investment income.
  • Robotic pets are growing so popular that Sherry Turkle, an MIT professor who studies the way we interact with technology, is uneasy about it: "The idea of some kind of artificial companionship," she says, "is already becoming the new normal."
  • robots will take over more and more jobs. And guess who will own all these robots? People with money, of course. As this happens, capital will become ever more powerful and labor will become ever more worthless. Those without money—most of us—will live on whatever crumbs the owners of capital allow us.
  • Economist Paul Krugman recently remarked that our long-standing belief in skills and education as the keys to financial success may well be outdated. In a blog post titled "Rise of the Robots," he reviewed some recent economic data and predicted that we're entering an era where the prime cause of income inequality will be something else entirely: capital vs. labor.
  • while it's easy to believe that some jobs can never be done by machines—do the elderly really want to be tended by robots?—that may not be true.
  • Third, as more people compete for fewer jobs, we'd expect to see middle-class incomes flatten in a race to the bottom.
  • The question we want to answer is simple: If CBTC is already happening—not a lot, but just a little bit—what trends would we expect to see? What are the signs of a computer-driven economy?
  • if automation were displacing labor, we'd expect to see a steady decline in the share of the population that's employed.
  • Second, we'd expect to see fewer job openings than in the past.
  • In the economics literature, the increase in the share of income going to capital owners is known as capital-biased technological change
  • Fourth, with consumption stagnant, we'd expect to see corporations stockpile more cash and, fearing weaker sales, invest less in new products and new factories
  • Fifth, as a result of all this, we'd expect to see labor's share of national income decline and capital's share rise.
  • We're already seeing them, and not just because of the crash of 2008. They started showing up in the statistics more than a decade ago. For a while, though, they were masked by the dot-com and housing bubbles, so when the financial crisis hit, years' worth of decline was compressed into 24 months. The trend lines dropped off the cliff.
  • Corporate executives should worry too. For a while, everything will seem great for them: Falling labor costs will produce heftier profits and bigger bonuses. But then it will all come crashing down. After all, robots might be able to produce goods and services, but they can't consume them
  • in another sense, we should be very alarmed. It's one thing to suggest that robots are going to cause mass unemployment starting in 2030 or so. We'd have some time to come to grips with that. But the evidence suggests that—slowly, haltingly—it's happening already, and we're simply not prepared for it.
  • the first jobs to go will be middle-skill jobs. Despite impressive advances, robots still don't have the dexterity to perform many common kinds of manual labor that are simple for humans—digging ditches, changing bedpans. Nor are they any good at jobs that require a lot of cognitive skill—teaching classes, writing magazine articles
  • in the middle you have jobs that are both fairly routine and require no manual dexterity. So that may be where the hollowing out starts: with desk jobs in places like accounting or customer support.
  • In fact, there's even a digital sports writer. It's true that a human being wrote this story—ask my mother if you're not sure—but in a decade or two I might be out of a job too
  • Doctors should probably be worried as well. Remember Watson, the Jeopardy!-playing computer? It's now being fed millions of pages of medical information so that it can help physicians do a better job of diagnosing diseases. In another decade, there's a good chance that Watson will be able to do this without any human help at all.
  • Take driverless cars.
  • The next step might be passenger vehicles on fixed routes, like airport shuttles. Then long-haul trucks. Then buses and taxis. There are 2.5 million workers who drive trucks, buses, and taxis for a living, and there's a good chance that, one by one, all of them will be displaced

  • we'll need to let go of some familiar convictions. Left-leaning observers may continue to think that stagnating incomes can be improved with better education and equality of opportunity. Conservatives will continue to insist that people without jobs are lazy bums who shouldn't be coddled. They'll both be wrong.
  • The modern economy is complex, and most of these trends have multiple causes.
  • we'll probably have only a few options open to us. The simplest, because it's relatively familiar, is to tax capital at high rates and use the money to support displaced workers. In other words, as The Economist's Ryan Avent puts it, "redistribution, and a lot of it."
  • would we be happy in a society that offers real work to a dwindling few and bread and circuses for the rest?
  • Most likely, owners of capital would strongly resist higher taxes, as they always have, while workers would be unhappy with their enforced idleness. Still, the ancient Romans managed to get used to it—with slave labor playing the role of robots—and we might have to, as well.
  •  economist Noah Smith suggests that we might have to fundamentally change the way we think about how we share economic growth. Right now, he points out, everyone is born with an endowment of labor by virtue of having a body and a brain that can be traded for income. But what to do when that endowment is worth a fraction of what it is today? Smith's suggestion: "Why not also an endowment of capital? What if, when each citizen turns 18, the government bought him or her a diversified portfolio of equity?"
  • In simple terms, if owners of capital are capturing an increasing fraction of national income, then that capital needs to be shared more widely if we want to maintain a middle-class society.
  • it's time to start thinking about our automated future in earnest. The history of mass economic displacement isn't encouraging—fascists in the '20s, Nazis in the '30s—and recent high levels of unemployment in Greece and Italy have already produced rioting in the streets and larger followings for right-wing populist parties. And that's after only a few years of misery.
  • When the robot revolution finally starts to happen, it's going to happen fast, and it's going to turn our world upside down. It's easy to joke about our future robot overlords—R2-D2 or the Terminator?—but the challenge that machine intelligence presents really isn't science fiction anymore. Like Lake Michigan with an inch of water in it, it's happening around us right now even if it's hard to see
  • A robotic paradise of leisure and contemplation eventually awaits us, but we have a long and dimly lit tunnel to navigate before we get there.

Why Her Is the Best Film of the Year - Christopher Orr - The Atlantic - 0 views

  • Though intimate in scope, Her is vast in its ambition. Every time it seems that Jonze may have played out the film’s semi-comic premise, he unveils an unexpected wrinkle, some new terrain of the mind or heart to be explored. Though the relationship between Theodore and Samantha forms the movie’s central thread, Jonze weaves in a variety of intricate counter-narratives, alternative lenses through which to view his subjects of inquiry:
  • Her is a remarkably ingenious film but, more important, it is a film that transcends its own ingenuity to achieve something akin to wisdom. By turns sad, funny, optimistic, and flat-out weird, it is a work of sincere and forceful humanism.
  • Like Eternal Sunshine of the Spotless Mind—of which Her is a clear descendant—Jonze’s film uses the tools of lightly scienced fiction to pose questions of genuine emotional and philosophical weight. What makes love real: the lover, the loved one, or the means by which love is conveyed? Need it be all three?

How people learn - The Week - 0 views

  • n a traditional classroom, the teacher stands at the front of the class explaining what is clear in their mind to a group of passive students. Yet this pedagogical strategy doesn't positively impact retention of information from lecture, improve understanding basic concepts, or affect beliefs (that is, does new information change your belief about how something works).
  • . Everything that constitutes "understanding" science and "thinking scientifically" resides in the long-term memory, which is developed via the construction and assembly of component proteins.

  • The results were similarly disturbing when students were tested to determine understanding of basic concepts. More instruction wasn't helping students advance from novice to expert. In fact, the data indicated the opposite: students had more novice-like beliefs after they completed a course than they had when they started.
  • But in addition, experts have a mental organizational structure that facilitates the retrieval and effective application of their knowledge.
  • experts have an ability to monitor their own thinking ("metacognition"), at least in their discipline of expertise. They are able to ask themselves, "Do I understand this? How can I check my understanding?"
  • But that is not what cognitive science tells us. It tells us instead that students need to develop these different ways of thinking by means of extended, focused mental effort.
  • new ways of thinking are always built on the prior thinking of the individual, so if the educational process is to be successful, it is essential to take that prior thinking into account.

  • "So it makes perfect sense," Wieman writes, "that they are not learning to think like experts, even though they are passing science courses by memorizing facts and problem-solving recipes."
  • Anything one can do to reduce cognitive load improves learning.
  • A second way teachers can improve instruction is by recognizing the importance of student beliefs about science
  • My third example of how teaching and learning can be improved is by implementing the principle that effective teaching consists of engaging students, monitoring their thinking, and providing feedback.
  • I assign students to groups the first day of class (typically three to four students in adjacent seats) and design each lecture around a series of seven to 10 clicker questions that cover the key learning goals for that day.
  • The process of critiquing each other's ideas in order to arrive at a consensus also enormously improves both their ability to carry on scientific discourse and to test their own understanding. [Change]

Are You a Workaholic? Blame Your Parents - Lauren Davidson - The Atlantic - 0 views

  • Career-oriented adults—your typical “workaholic”—value the social status and prestige that comes with professional achievement, and derive much of their identity from their jobs.
  • do have a notable effect on whether children have a job-orientation mentality. Adolescents who are close to their mothers are less likely to view work as just a job when they grow up, probably because they’ve been raised to value social, rather than instrumental, life experiences.

As our capitalist society favors money and professional achievement, a child with two calling-oriented parents is more likely to have the confidence to ignore these societal pressures and pursue her dreams.
  • Children can affect their parents’ work ethic, too. Allowing people to bring their children into the office has been shown to boost efficiency and productivity—and could help raise that next generation of career-oriented workers.

So What If Everyone at Harvard Gets an A? - Eleanor Barkhorn - The Atlantic - 1 views

  • Yesterday, we ran a story about a rather astonishing fact that the Harvard Crimson uncovered: The most common grade at Harvard is an A.

  • At large universities where thousands are admitted, bell-curve grading is used to "flunk out" many freshmen. Very different in Ivy League. Bell-curve grading, which assures a percent of low grades & failures, is a cruel academic necessity in some quarters. Encourages cheating.

  • saw our time at Princeton as a reward, not an opportunity to push ourselves again, even harder. The university's relatively lax grading policies only encouraged that mentality.
  • Starting my junior fall, professors could give out only a limited number of A-range grades. The change prompted lots of anxiety and indignation from the student body—and now, nine years later, it may be rolled back. But for me, "grade deflation" was a much-needed kick in the pants. I started reading more carefully, taking more diligent notes, developing relationships with my professors and their teaching assistants. I ended up learning a lot more
  • Yes, hard-working students should be rewarded with good grades. But a very good way to inspire students to work hard in the first place is to make good grades worth something.

Missing Links: Access to Papers' Raw Data Plummets by 17% Each Year - Megan Garber - The Atlantic - 0 views

  • While data for almost all of the studies published as recently as 2011 were still accessible, the chances of them remaining accessible fell by a whopping 17 percent each year. Each year. For research from the not-that-distant early 1990s, data availability dropped to as little as 20 percent.
  • A recent study of Supreme Court decisions—the rhetorical documents of the highest judicial body in the land—found that 49 percent of the web links cited within those decisions are now dead.

Thomas Piketty Tours U.S. for His New Book - NYTimes.com - 0 views

  • The response from  fellow economists, so far mainly from the liberal side of the spectrum, has verged on the rapturous. Mr. Krugman,  a columnist for The New York Times, predicted in The New York Review of Books that Mr. Piketty’s book would “change both the way we think about society and the way we do economics.”
  • Mr. Piketty’s dedication to data has long made him a star among economists, who credit his work on income inequality (with Emmanuel Saez and others) for diving deep into seemingly dull tax archives to bring an unprecedented historical perspective to the subject.
  • Six years after the financial crisis, “people are looking for a bible of sorts,” said Julia Ott, an assistant professor of the history of capitalism at the New School, who appeared on a panel with Mr. Piketty at New York University on Thursday. “He’s speaking to a real feeling out there that things haven’t been fixed, that we need to take stock, that we need big ideas, big proposals, big global solutions.”
  • ...3 more annotations...
  • At the book’s center is Mr. Piketty’s contention — contrary to the influential theory developed by Simon Kuznets in the 1950s and ’60s — that mature capitalist economies do not inevitably evolve toward greater economic equality. Instead, Mr. Piketty contends, the data reveals a deeper historical tendency for the rate of return on capital to outstrip the overall rate of economic growth, leading to greater and greater concentrations of wealth at the very top.
  • Mr. Piketty rejected any economic determinism. “It all depends on what the political system decides,” he said.
  • Mr. Piketty, who writes in the book that the collapse of Communism in 1989 left him “vaccinated for life” against the “lazy rhetoric of anticapitalism,” is no Marxian revolutionary. “I believe in private property,” he said in the interview. “But capitalism and markets should be the slave of democracy and not the opposite.”

"There are a lot of pharmaceutical and digital tools that have been able to boost our ability to think. Adderall, Provigil, and extra-cortical technologies."
  • Back in 2008, 20 percent of scientists reported using brain-enhancing drugs. And I spoke with dozens of readers who had complex regimens, including, for example, a researcher at the MIT-affiliated Whitehead Institute for Biomedical Research. "We aren't the teen clubbers popping uppers to get through a hard day running a cash register after binge drinking," the researcher told me. "We are responsible humans." Responsible humans trying to get an edge in incredibly competitive and cognitively demanding fields.

Who You Are on Facebook Is Probably Pretty Much Who You Are - Megan Garber - Technology - The Atlantic - 3 views

  • , Dr. Sam Gosling and his colleagues first asked participants to complete the Ten Item Personality Inventory, which asked them to assess the extent to which factors like extroversion, anxiety, and calmness applied to them. The researchers used the results of those surveys to assess the participants according to the big five personality traits: openness, conscientiousness, extroversion, agreeableness, and neuroticism. They then compared those findings to the information represented in participants' Facebook profiles
  • What the researchers found was a big correlation between the personalities represented on Facebook and the personalities suggested by the test. The extroverts had more Facebook friends than the introverts; those who were open to new people and experiences in the physical world replicated that tendency in the digital. "The study determined that online social networks are not an escape from reality," RWW's Alicia Eler put it, "but rather a microcosm of peoples' larger social worlds and an extension of offline behaviors."

Social Connection Makes a Better Brain - Emily Esfahani Smith - The Atlantic - 0 views

  • Recent trends show that people increasingly value material goods over relationships—but neuroscience and evolution say this goes against our nature.
  • Do you prioritize your career or your relationships?
  • “Man is by nature a social animal … Anyone who either cannot lead the common life or is so self-sufficient as not to need to, and therefore does not partake of society, is either a beast or a god.”

  • Just as human beings have a basic need for food and shelter, we also have a basic need to belong to a group and form relationships.
  • Lieberman sees the brain as the center of the social self. Its primary purpose is social thinking.
  • Every time we are not engaged in an active task—like when we take a break between two math problems—the brain falls into a neural configuration called the “default network.” When you have down time, even if it’s just for a second, this brain system comes on automatically.
  • “The default network directs us to think about other people’s minds—their thoughts, feelings, and goals.”
  • “Evolution has made a bet,” Lieberman tells me, “that the best thing for our brain to do in any spare moment is to get ready for what comes next in social terms.”
  • When economists put a price tag on our relationships, we get a concrete sense of just how valuable our social connections are—and how devastating it is when they are broken.
  • If you have a friend that you see on most days, it’s like earning $100,000 more each year.
  • To the brain, social pain feels a lot like physical pain—a broken heart can feel like a broken leg, as Lieberman puts it in his book.
  • But over the last fifty years, while society has been growing more and more prosperous and individualistic, our social connections have been dissolving.
  • Over the same period of time that social isolation has increased, our levels of happiness have gone down, while rates of suicide and depression have multiplied. 
  • Across the board, people are increasingly sacrificing their personal relationships for the pursuit of wealth.

Recruitment, Resumes, Interviews: How the Hiring Process Favors Elites - The Atlantic - 0 views

  • As income inequality in the U.S. strikes historic highs, many people are starting to feel that the American dream is either dead or out of reach. Only 64 percent of Americans still believe that it’s possible to go from rags to riches, and, in another poll, 63 percent said they did not believe their children would be better off than they were. These days, the idea that anyone who works hard can become wealthy is at best a tough sell.
  • What ends up happening is that firms create lists. So there's a school list, and on the list there are cores and there are targets. Cores are generally the most prestigious schools; targets are highly prestigious schools. Cores receive the most love. But basically if you're not from one of these cores or target schools it's extremely hard to get into one of these firms.
  • But in terms of inequality, what ends up happening is if you're not at one of those schools, the only way to really get into one these firms is to have a personal connection to someone who already works there.
  • ...3 more annotations...
  • Part of the reason this happens at these firms in particular is just very logistical. The firms end up dedicating HR staff to a specific school—so they'll have a team for Harvard, they'll have a team for Princeton, Columbia, Stanford, and so forth. When you are from one of those schools and you submit your resume, there's a designated person or team whose job it is to review your resume. When you're not at one of those listed schools what ends up happening is that your resume just goes into this big broad bucket where they may or may not be a certain person who's charged with reviewing those resumes.
  • But you may not be identifying people who are best at the job and, crucially, you're restricting the class diversity and racial diversity to those who tend to attend the most elite schools.
  • But this creates a Catch 22 in two ways: The first is that individuals who come from socio-economically disadvantaged backgrounds don't often know that telling these deeply personal stories is appropriate. Second, some people actually want to hide information about coming from an underprivileged background because they think it could harm the perceptions of fit. So they don't know that telling these stories can be advantageous.

Enlightenment's Evil Twin - The Atlantic - 0 views

  • The first time I can remember feeling like I didn’t exist, I was 15. I was sitting on a train and all of a sudden I felt like I’d been dropped into someone else’s body. My memories, experiences, and feelings—the things that make up my intrinsic sense of “me-ness”—projected across my mind like phantasmagoria, but I felt like they belonged to someone else. Like I was experiencing life in the third person.
  • It’s characterized by a pervasive and disturbing sense of unreality in both the experience of self (called “depersonalization”) and one’s surroundings (known as “derealization”); accounts of it are surreal, obscure, shrouded in terms like “unreality” and “dream,” but they’re often conveyed with an almost incongruous lucidity.
  • It’s not a psychotic condition; the sufferers are aware that what they’re perceiving is unusual. “We call it an ‘as if’ disorder. People say they feel as if they’re in a movie, as if they’re a robot,” Medford says.

  • Studies carried out with college students have found that brief episodes are common in young people, with a prevalence ranging from 30 to 70 percent. It can happen when you’re jet-lagged, hungover, or stressed. But for roughly 1 to 2 percent of the population, it becomes persistent, and distressing
  • Research suggests that areas of the brain that are key to emotional and physical sensations, such as the amygdala and the insula, appear to be less responsive in chronic depersonalization sufferers. You might become less empathetic; your pain threshold might increase. These numbing effects mean that it’s commonly conceived as a defense mechanism; Hunter calls it a “psychological trip switch” which can be triggered in times of stress.
  • Have you ever played that game when you repeat a word over and over again until it loses all meaning? It’s called semantic satiation. Like words, can a sense of self be broken down into arbitrary, socially-constructed components?
  • That question may be why the phenomenon has attracted a lot of interest from philosophers. In a sense, the experience presupposes certain notions of how the self is meant to feel. We think of a self as an essential thing—a soul or an ego that everyone has and is aware of—but scientists and philosophers have been telling us for a while now that the self isn’t quite as it seems
  • there is no center in the brain where the self is generated. “What we experience is a powerful depiction generated by our brains for our benefit,” he writes. Brains make sense of data that would otherwise be overwhelming. “Experiences are fragmented episodes unless they are woven together in a meaningful narrative,” he writes, with the self being the story that “pulls it all together.”
  • “The unity [of self that] we experience, which allows us legitimately to talk of ‘I,’ is a result of the Ego Trick—the remarkable way in which a complicated bundle of mental events, made possible by the brain, creates a singular self, without there being a singular thing underlying it,”
  • depersonalization is both a burden, a horrible burden—but it’s in some strange way a blessing, to reach some depths, some meaning which somehow comes only in the broken mirror,” Bezzubova says. “It’s a Dostoyevsky style illumination—where clarity cannot be distinguished from pain.”
  • for her, the experience is pleasant. “It’s helped me in my life,” she says. Over the past few years, she has learned to interpret her experiences in a Buddhist context, and she describes depersonalization as a “deconditioning” of sorts: “The significance I place on the world is all in my mind,”
  • “I believe I am on the path to enlightenment,” she says.
  • Mindfulness has become increasingly popular in the West over the past few years, but as Britton told The Atlantic, the practice in its original form isn’t just about relaxation: It’s about the often painstaking process of coming to terms with three specific insights of the Theravadin Buddhist tradition, which are anicca, or impermanence; dukkha, or dissatisfaction; and anatta, or not-self.
  • The crossover between dark mental states and Buddhist practices is being investigated
  • depersonalization must cause the patient distress and have an impact on her daily functioning for it to be classified as clinically significant. In this sense, it seems inappropriate to call Alice’s experiences pathological. “We have ways of measuring disorders, but you have to ask if it’s meaningful. It’s an open question,”
  • “I think calling it a loss of self is maybe a convenient shorthand for something that’s hard to capture,” he says. “I prefer to talk about experience—because that’s what’s important in psychiatry.”

Hard Feelings: Science's Struggle to Define Emotions - The Atlantic - 0 views

  • Most psychology research at the time was focused on behaviorism—classical conditioning and the like. Silvan Tomkins was the one other person Ekman knew of who was studying emotions, and he’d done a little work on facial expressions that Ekman saw as extremely promising.
  • And so the six emotions used in Ekman’s studies came to be known as the “basic emotions” all humans recognize and experience. Some researchers now say there are fewer than six basic emotions, and some say there are more (Ekman himself has now scaled up to 21), but the idea remains the same:
  • Emotions are biologically innate, universal to all humans, and displayed through facial expressions

  • Across cultures, people tended to match smiling faces with “happiness,”
  • furrow-browed, tight-lipped faces with “anger,” and so on.
  • “It’s been said that there are as many theories of emotions as there are emotion theorists,” says Joseph LeDoux, a professor of neuroscience and the director of the Emotional Brain Institute and the Nathan Kline Institute for Psychiatric Research at New York University.
