Six Vintage-Inspired Animations on Critical Thinking | Brain Pickings - 0 views

  •  
    Australian outfit Bridge 8, who have the admirable mission of devising "creative strategies for science and society," have put together six fantastic two-minute animations on various aspects of critical thinking, aimed at kids ages 8 to 10 but also designed to resonate with grown-ups. Inspired by the animation style of the 1950s, most recognizably Saul Bass, the films are designed to promote a set of educational resources on critical thinking by TechNYou, an emerging technologies public information project funded by the Australian government.

The Poverty of an Idea - NYTimes.com - 1 views

  • THE libertarian writer Charles Murray has probably done more than any other contemporary thinker to keep alive the idea of a “culture of poverty,” the theory that poor people are trapped by distorted norms and aspirations and not merely material deprivation.
  • Harrington had picked up the idea of a “culture of poverty” from the anthropologist Oscar Lewis, whose 1959 study of Mexican slum dwellers identified a “subculture” of lowered aspirations and short-term gratification. Echoing Lewis, Harrington argued that American poverty constituted “a separate culture, another nation, with its own way of life.” It would not be solved merely by economic expansion or moral exhortation, he contended, but by a “comprehensive assault on poverty.”
  • In his view, these problems were not a judgment on the poor as individuals, but on a society indifferent to their plight. His popularization of the phrase “culture of poverty” has unintended consequences. There was nothing  in the “vicious circle” of pathology he sketched that was culturally determined, but in the hands of others, the idea came to signify an ingrained system of norms passed from generation to generation.

  • Conservatives took the attitudes and behaviors Harrington saw as symptoms of poverty and portrayed them as its direct causes.
  • In his 1984 book, “Losing Ground,” Mr. Murray argued that welfare programs abet rather than ameliorate poverty. The book dismissed Harrington’s prescription for ending poverty, and Harrington returned the favor. In “The New American Poverty,” published the same year, he called Mr. Murray the right-wing equivalent of a “vulgar Marxist,” a social theorist who believed in a “one-to-one relationship between the economic and the political or the psychological.”
  • Harrington’s culture-of-poverty thesis was at best an ambiguous impediment to understanding — in later books, he made no use of the term. But in its moral clarity, “The Other America” was ultimately optimistic; it was less an indictment and more an appeal to Americans to live up to their better instincts.

Other People's Suffering - NYTimes.com - 0 views

  • members of the upper class are more likely than others to behave unethically, to lie during negotiations, to drive illegally and to cheat when competing for a prize.“Greed is a robust determinant of unethical behavior,” the authors conclude. “Relative to lower-class individuals, individuals from upper-class backgrounds behaved more unethically in both naturalistic and laboratory settings.”
  • Our findings suggest that when a person is suffering, upper-class individuals perceive these signals less well on average, consistent with other findings documenting reduced empathic accuracy in upper-class individuals (Kraus et al., 2010). Taken together, these findings suggest that upper-class individuals may underestimate the distress and suffering in their social environments.
  • each participant was assigned to listen, face to face, from two feet away, to someone else describing real personal experiences of suffering and distress.The listeners’ responses were measured two ways, first by self-reported levels of compassion and second by electrocardiogram readings to determine the intensity of their emotional response. The participants all took a test known as the “sense of power” scale, ranking themselves on such personal strengths and weaknesses as ‘‘I can get people to listen to what I say’’ and ‘‘I can get others to do what I want,” as well as ‘‘My wishes do not carry much weight’’ and ‘‘Even if I voice them, my views have little sway,’’ which are reverse scored.The findings were noteworthy, to say the least. For “low-power” listeners, compassion levels shot up as the person describing suffering became more distressed. Exactly the opposite happened for “high-power” listeners: their compassion dropped as distress rose.

  • Who fits the stereotype of the rich and powerful described in this research? Mitt Romney. Empathy: “I’m not concerned about the very poor.” Compassion: “I like being able to fire people who provide services to me.” Sympathy for the disadvantaged: My wife “drives a couple of Cadillacs.” Willingness to lie in negotiations: “I was a severely conservative Republican governor.”
  • 48 percent described the Democratic Party as “weak,” compared to 28 percent who described the Republican Party that way. Conversely, 50 percent said the Republican Party is “cold hearted,” compared to 30 percent who said that was true of the Democrats.
  • This is the war that is raging throughout America. It is between conservatives, who emphasize personal responsibility and achievement, against liberals, who say the government must take from the wealthy and give to the poor. So it will be interesting this week to see if President Obama can rally the country to support his vision of a strong social compact. He has compassion on his side. Few Americans want to see their fellow citizens suffer. But the president does have that fiscal responsibility issue haunting him because the country remains in dire trouble.
  • For power holders, the world is viewed through an instrumental lens, and approach is directed toward those individuals who populate the useful parts of the landscape. Our results suggest that power not only channels its possessor’s energy toward goal completion but also targets and attempts to harness the energy of useful others. Thus, power appears to be a great facilitator of goal pursuit through a combination of intrapersonal and interpersonal processes. The nature of the power holder’s goals and interpersonal relationships ultimately determine how power is harnessed and what is accomplished in the end.
  • Republicans recognize the political usefulness of objectification, capitalizing on “compassion fatigue,” or the exhaustion of empathy, among large swathes of the electorate who are already stressed by the economic collapse of 2008, high levels of unemployment, an epidemic of foreclosures, stagnant wages and a hyper-competitive business arena.
  • . Republican debates provided further evidence of compassion fatigue when audiences cheered the record-setting use of the death penalty in Texas and applauded the prospect of a gravely ill pauper who, unable to pay medical fees, was allowed to die.Even Rick Santorum, who has been described by the National Review as holding “unstinting devotion to human dignity” and as fluent in “the struggles of the working class,” wants to slash aid to the poor. At a Feb. 21 gathering of 500 voters in Maricopa County, Ariz., Santorum brought the audience to its feet as he declared:We need to take everything from food stamps to Medicaid to the housing programs to education and training programs, we need to cut them, cap them, freeze them, send them to the states, say that there has to be a time limit and a work requirement, and be able to give them the flexibility to do those programs here at the state level.
  • President Obama has a substantial advantage this year because he does not have a primary challenger, which frees him from the need to emphasize his advocacy for the disempowered — increasing benefits or raising wages for the poor. This allows him to pick and chose the issues he wants to address.At the same time, compassion fatigue may make it easier for the Republican nominee to overcome the liabilities stemming from his own primary rhetoric, to reach beyond the core of the party to white centrist voters less openly drawn to hard-edged conservatism. With their capacity for empathy frayed by a pervasive sense of diminishing opportunity and encroaching shortfall, will these voters once again become dependable Republicans in 2012?

    Do you agree with Edsall? I think he is definitely taking an anti-Republican stance, but the findings are interesting.

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.
  • 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
  • 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.”
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

How Dangerous Neighborhoods Make You Feel Paranoid | TIME.com - 0 views

  • Simply walking through a sketchy-looking neighborhood can make you feel more paranoid and lower your trust in others
  • In a study published in the journal PeerJ, student volunteers who spent less than an hour in a more dangerous neighborhood showed significant changes in some of their social perceptions.
  • The researchers’ goal was to investigate the relationship between lower income neighborhoods and reduced trust and poor mental health.
  • ...10 more annotations...
  • from Newcastle University in the UK, wanted to determine whether the connection was due to people reacting to the environment around them, or because those who are generally less trusting were more likely to live in troubled areas. Prior research showed that kids who grew up in such neighborhoods were less likely to graduate from high school and more likely to develop stress that can lead to depression.
  • The study took 50 students, sent half of them to a low income, high crime neighborhood and the other half to an affluent neighborhood with little crime.
  • Before the students ventured into their respective areas, the researchers interviewed the neighborhood residents and found that residents of the high-crime neighborhood harbored more feelings of paranoia and lower levels of social trust compared to the residents of the other neighborhood.
  • The students in the study were not from either neighborhood, and did not know what the study was about. They were were dropped off by a taxi and told to deliver envelopes containing a packet of questions to a list of residential addresses. They spent 45 minutes walking around their assigned neighborhood distributing the envelopes. When the students returned, the researchers surveyed them about their experience, their feelings of trust, and their feelings of paranoia.
  • Despite the short amount of time they spent in the neighborhoods, the students picked up the prevailing social attitudes of the residents living in those environments; those who went to the more dangerous neighborhood scored higher on measures of paranoia and lower on measures of trust compared to the other group, just as the residents had.
  • Not only that, but their levels of reported paranoia and trust were indistinguishable from the residents who spent years living there.
  • That came as an intriguing surprise to other experts. Ingrid Gould Ellen, the director of the Urban Planning Program at New York University Wagner Graduate School of Public Service, studies how the make-up of neighborhoods can impact the attitudes and interactions of people who live in them
  • found that kids who live on blocks where violent crimes occurred the week before they took a standardized test performed worse on those tests than students from similar backgrounds who were not exposed to a violent crime in their neighborhood before their exam.
  • paranoia and lack of trust set in after just a short time in the more troubled neighborhood suggested how powerful the influence of these environments can be.
  • For urban planners, the findings confirm what most probably understood instinctively — that people do tend to make snap judgments about both their environments and the people in them based on visual cues such as broken windows and abandoned houses. But the results also show how these cues can influence deeper perceptions and mental states as well.

  • Formal schooling is terribly important; it helps you think in the way that IQ testers like.
  • In 1910, schools were focused on kids memorizing things about the real world. Today, they are entirely about relationships.
  • One of the fundamental things is the switch from “utilitarian spectacles” to “scientific spectacles.” The fact that we wear scientific spectacles doesn’t mean that we actually know a lot about science.
  • in 1900 in America, if you asked a child, what do dogs and rabbits have in common, they would say, “Well, you use dogs to hunt rabbits.” This is not the answer that the IQ tests want. They want you to classify. Today, a child would be likely to say, “They are both animals.” They picked up the habit of classification and use the vocabulary of science.
  • we have learned to use logic to attack the hypothetical. We have an ability to deal with a much wider range of problems than our ancestors would.
  • In 1950, teenagers could not only understand their parents, but they could also mimic their speech. Today, teenagers can still understand their parents. Their passive vocabularies are good enough. But when it comes to the words they actively use, they are much less capable of adult speak.
  • The brighter you are, the quicker after the age of 65 you have a downward curve for your analytic abilities
  • Retire from your job, but read great literature. Read about the history of science. Try and keep up your problem solving skills
  • One of the most interesting predictions is what will happen to the developing world. If they industrialize, in theory, they should have the explosive IQ gains in the coming century that we had in the last century.

The Smart Set: I Have My Reasons - May 24, 2011 - 0 views

  • Wasn’t the Enlightenment supposed to wash the world of its sins of superstition and religion? And yet humanity keeps clinging to its belief systems, its religious leaders, and its prayer. More than that, we’re dipping back into the magical realms — one would think that if superstition were to be eradicated through the power of reason and rationality, magic would be the first to go. It turns out our hunger for the irrational and the intuitive is more insatiable than previously assumed. We have our Kabbalah, our Chaos Magick, our Druids. We have our mystics and tarot card readers and our astrologers on morning news shows explaining why Kate and William are a match made by the gods. Wicca is a fast growing religion in the United States, and my German health insurance covers homeopathy and Reiki massage, both of which have always felt more like magic than science to me.
  • And yet the atheists keep on, telling us that we don’t have to believe in God. It maybe never occurred to them that perhaps we want to.
  • Magical belief, whether that entails an omnipotent God who watches over us or the conviction that we can communicate with “the other side,” fills a need in us. Some of us, I should say, as atheists would be quick to counter. How seriously we take that belief, and what we do with it varies from person to person. As the debates between the godless and the faithful continue — and these are so prevalent in our culture now, the religious figure versus the atheist, sponsored by every university and cultural center, that I read such a debate in a novel I had picked up — that perhaps these two kinds of people simply have a different set of needs. It’s like a new mother arguing with a woman who has never felt maternal a day in her life. Neither side will ever truly understand the longings of the other, and the fact that they can’t stop arguing and trying to convince is proof of that.

The Washington Monthly - The Magazine - The Information Sage - 0 views

  • PowerPoint, a software program that Tufte says is constricting and obfuscating and “turns information into a sales pitch.”
  • Tufte dissected NASA’s PowerPoint slides on his Web site, showing that the program didn’t allow engineers to write in scientific notation and replaced complex quantitative measurement with imprecise words like “significant.” He then published a twenty-eight-page essay called “The Cognitive Style of PowerPoint,” in which he analyzed hundreds of existing PowerPoint slides and showed that the statistical graphics used in PowerPoint presentations show an average of twelve numbers each, which, in Tufte’s analysis, ranks it below every major world publication except for Pravda. The low information density of PowerPoint is “approaching dementia,” he wrote.
  • the reliance on PowerPoint often means that battle orders are rendered in incomplete, often unclear sentences and maps are squashed and stripped of meaningful detail, leaving essential battlefield questions of geography dangerously unclear. The details are classified, but Hammes told me that he has seen war plans for the Korean peninsula prepared in PowerPoint in which massive terrain issues were completely glossed over. On the whole, Hammes told me, the rise of PowerPoint in the military has made the decision-making process less intellectually active. And Tufte, he added, “is the master on this whole thing.”

  • Nate Silver, who runs the political Web site FiveThirtyEight, now part of the New York Times, uses many of Tufte’s maxims in the site’s design. Silver told me that he tries to keep the “data-ink” ratio of his current site very high, meaning most of the pixels on the screen show actual numbers or data points; he also thinks of the site’s design in terms of “small multiples,” another Tufte neologism that refers to a series of related numbers that reveal subtle differences over time. “Tufte treats data like good writing,” he said. “You have a certain thought—how clearly and beautifully are you conveying it?”
  • Good design, then, is not about making dull numbers somehow become magically exhilarating, it is about picking the right numbers in the first place. “It’s about data that matters to you,”

  • present shock keeps us suspended in a state of constant disarray, and causes us to prioritize the recent over the relevant and the new instead of the most important.
  • The way we use technology could be reshaping our sense of time and urgency. Douglas Rushkoff, the author of “Present Shock: When Everything Happens Now,” describes present shock as the stupefaction that overtakes people as they try to keep up with the never-ending onslaught of status updates, photo feeds and looping videos constantly refreshing before their eyes.
  • THERE are other signs to indicate a replay aesthetic is coming to the Web. For example, the latest version of the iPhone’s mobile software will include the ability to capture video in slow motion.
  • the medium of the loop — either in a GIF, a short clip posted to Vine, or Instagram photo- and video-sharing applications — has become a crucial framework for transmitting information. It mimics the way we remember — by repetition — and future tools could make use of that to understand not only how we transmit information but also how we retain it.
  • Perhaps the replay Web, by allowing us to constantly revisit and reconsider the recent past, can help us find new meaning in it.

The Dangers of Pseudoscience - NYTimes.com - 0 views

  • the “demarcation problem,” the issue of what separates good science from bad science and pseudoscience (and everything in between). The problem is relevant for at least three reasons.
  • The first is philosophical: Demarcation is crucial to our pursuit of knowledge; its issues go to the core of debates on epistemology and of the nature of truth and discovery.
  • The second reason is civic: our society spends billions of tax dollars on scientific research, so it is important that we also have a good grasp of what constitutes money well spent in this regard.
  • ...18 more annotations...
  • Third, as an ethical matter, pseudoscience is not — contrary to popular belief — merely a harmless pastime of the gullible; it often threatens people’s welfare,
  • It is precisely in the area of medical treatments that the science-pseudoscience divide is most critical, and where the role of philosophers in clarifying things may be most relevant.
  • some traditional Chinese remedies (like drinking fresh turtle blood to alleviate cold symptoms) may in fact work
  • There is no question that some folk remedies do work. The active ingredient of aspirin, for example, is derived from willow bark, which had been known to have beneficial effects since the time of Hippocrates. There is also no mystery about how this happens: people have more or less randomly tried solutions to their health problems for millennia, sometimes stumbling upon something useful
  • What makes the use of aspirin “scientific,” however, is that we have validated its effectiveness through properly controlled trials, isolated the active ingredient, and understood the biochemical pathways through which it has its effects
  • In terms of empirical results, there are strong indications that acupuncture is effective for reducing chronic pain and nausea, but sham therapy, where needles are applied at random places, or are not even pierced through the skin, turn out to be equally effective (see for instance this recent study on the effect of acupuncture on post-chemotherapy chronic fatigue), thus seriously undermining talk of meridians and Qi lines
  • Asma at one point compares the current inaccessibility of Qi energy to the previous (until this year) inaccessibility of the famous Higgs boson,
  • But the analogy does not hold. The existence of the Higgs had been predicted on the basis of a very successful physical theory known as the Standard Model. This theory is not only exceedingly mathematically sophisticated, but it has been verified experimentally over and over again. The notion of Qi, again, is not really a theory in any meaningful sense of the word. It is just an evocative word to label a mysterious force
  • Philosophers of science have long recognized that there is nothing wrong with positing unobservable entities per se, it’s a question of what work such entities actually do within a given theoretical-empirical framework. Qi and meridians don’t seem to do any, and that doesn’t seem to bother supporters and practitioners of Chinese medicine. But it ought to.
  • what’s the harm in believing in Qi and related notions, if in fact the proposed remedies seem to help?
  • we can incorporate whatever serendipitous discoveries from folk medicine into modern scientific practice, as in the case of the willow bark turned aspirin. In this sense, there is no such thing as “alternative” medicine, there’s only stuff that works and stuff that doesn’t.
  • Second, if we are positing Qi and similar concepts, we are attempting to provide explanations for why some things work and others don’t. If these explanations are wrong, or unfounded as in the case of vacuous concepts like Qi, then we ought to correct or abandon them.
  • pseudo-medical treatments often do not work, or are even positively harmful. If you take folk herbal “remedies,” for instance, while your body is fighting a serious infection, you may suffer severe, even fatal, consequences.
  • Indulging in a bit of pseudoscience in some instances may be relatively innocuous, but the problem is that doing so lowers your defenses against more dangerous delusions that are based on similar confusions and fallacies. For instance, you may expose yourself and your loved ones to harm because your pseudoscientific proclivities lead you to accept notions that have been scientifically disproved, like the increasingly (and worryingly) popular idea that vaccines cause autism.
  • Philosophers nowadays recognize that there is no sharp line dividing sense from nonsense, and moreover that doctrines starting out in one camp may over time evolve into the other. For example, alchemy was a (somewhat) legitimate science in the times of Newton and Boyle, but it is now firmly pseudoscientific (movements in the opposite direction, from full-blown pseudoscience to genuine science, are notably rare).
  • The verdict by philosopher Larry Laudan, echoed by Asma, that the demarcation problem is dead and buried, is not shared by most contemporary philosophers who have studied the subject.
  • the criterion of falsifiability, for example, is still a useful benchmark for distinguishing science and pseudoscience, as a first approximation. Asma’s own counterexample inadvertently shows this: the “cleverness” of astrologers in cherry-picking what counts as a confirmation of their theory, is hardly a problem for the criterion of falsifiability, but rather a nice illustration of Popper’s basic insight: the bad habit of creative fudging and finagling with empirical data ultimately makes a theory impervious to refutation. And all pseudoscientists do it, from parapsychologists to creationists and 9/11 Truthers.
  • The borderlines between genuine science and pseudoscience may be fuzzy, but this should be even more of a call for careful distinctions, based on systematic facts and sound reasoning. To try a modicum of turtle blood here and a little aspirin there is not the hallmark of wisdom and even-mindedness. It is a dangerous gateway to superstition and irrationality.

The exoneration of Kash Register and the problem of false eyewitness testimony. - 0 views

  • according to Brandon Garrett, a law professor at the University of Virginia and the author of Convicting the Innocent, eyewitness misidentifications have played a leading role in nearly 75 percent of 250 convictions overturned by DNA evidence between 1989 and 2010. In more than one-half of those exonerations, the eyewitnesses start off unsure, a “glaring sign” of potential trouble as Garrett puts it, yet appear to become increasingly certain over time. This often corresponds with police practices like suggestive photo arrays, lineups, and even well-intentioned comments like “Good job!” after a witness makes an identification, however tentative. All of this can cause “contamination” of memory, Garrett says so that “there is no way to know after the fact whether the eyewitness could have actually picked the person with any degree of confidence.”

Maternal Antibodies Linked to Autism | The Scientist Magazine® - 0 views

  • WIKIPEDIA, KEN HAMMOND (USDA)In 2008, Judy van de Water from the University of California, Davis, discovered a group of autoantibodies—those that trigger immune responses against the body’s own molecules—that are especially common in mothers of children with autism.
  • “Given that, at present, only between 15 and 20 percent of children with autism have known causes—mainly genetic and infectious mechanisms—this will be a major advance.”
  • “It would allow mothers to plan,” said van de Water, by enrolling their children in educational programs that promote social skills from an early age.

  • team is now working to address these issues, trying to identify the specific parts of the six proteins that the antibodies stick to, determine how they affect the developing brain, and understand how they might be used to predict autism risk. Van de Water and Amaral are consulting for Pediatric Bioscience, which is creating a predictive test based on the results.
  • the team’s colleagues Melissa Bauman and David Amaral, also from UC Davis, injected eight pregnant rhesus monkeys with antibodies purified from mothers with autistic children.
  • Moving this to monkeys is a big step,
  • next step is to come up with a therapeutic to block the antibodies—not just to pick them up, but to do something about it,”
  • The parents have been surprisingly supportive,” she said. “But the autism field has been fraught with false alarms, so we want to be really careful.”

An Adaptation From 'Flash Boys: A Wall Street Revolt,' by Michael Lewis - NYTimes.com - 0 views

  • Ryan was making hundreds of thousands of dollars a year building systems to make stock-market trades faster. He was struck, over and over again, by how little those he helped understood the technology they were using
  • Ryan described what he witnessed inside the exchanges: The frantic competition for nanoseconds, clients’ trying to get their machines closer to the servers within the exchanges, the tens of millions being spent by high-frequency traders for tiny increments of speed. The U.S. stock market was now a class system of haves and have-nots, only what was had was not money but speed (which led to money).
  • A salesman at RBC who marketed Thor recalls one big investor calling to say, “You know, I thought I knew what I did for a living, but apparently not, because I had no idea this was going on.”
  • ...8 more annotations...
  • Eventually Brad Katsuyama came to realize that the most sophisticated investors didn’t know what was going on in their own market. Not the big mutual funds, Fidelity and Vanguard. Not the big money-management firms like T. Rowe Price and Capital Group. Not even the most sophisticated hedge funds.
  • The deep problem with the system was a kind of moral inertia. So long as it served the narrow self-interests of everyone inside it, no one on the inside would ever seek to change it, no matter how corrupt or sinister it became
  • Technology had collided with Wall Street in a peculiar way. It had been used to increase efficiency. But it had also been used to introduce a peculiar sort of market inefficiency. Taking advantage of loopholes in some well-meaning regulation introduced in the mid-2000s, some large amount of what Wall Street had been doing with technology was simply so someone inside the financial markets would know something that the outside world did not. The same system that once gave us subprime-mortgage collateralized debt obligations no investor could possibly truly understand now gave us stock-market trades involving fractions of a penny that occurred at unsafe speeds using order types that no investor could possibly truly understand.
  • The trouble with the stock market — with all of the public and private exchanges — was that they were fantastically gameable, and had been gamed: first by clever guys in small shops, and then by prop traders who moved inside the big Wall Street banks. That was the problem, Puz thought. From the point of view of the most sophisticated traders, the stock market wasn’t a mechanism for channeling capital to productive enterprise but a puzzle to be solved.
  • As they worked through the order types, the Puzzle Masters created a taxonomy of predatory behavior in the stock market. Broadly speaking, it appeared as if there were three activities that led to a vast amount of grotesquely unfair trading. The first they called electronic front-running — seeing an investor trying to do something in one place and racing ahead of him to the next (what had happened to Katsuyama when he traded at RBC). The second they called rebate arbitrage — using the new complexity to game the seizing of whatever legal kickbacks, called rebates within the industry, the exchange offered without actually providing the liquidity that the rebate was presumably meant to entice. The third, and probably by far the most widespread, they called slow-market arbitrage. This occurred when a high-frequency trader was able to see the price of a stock change on one exchange and pick off orders sitting on other exchanges before those exchanges were able to react. This happened all day, every day, and very likely generated more billions of dollars a year than the other strategies combined.
  • IEX had made its point: That to function properly, a financial market didn’t need to be rigged in someone’s favor. It didn’t need payment for order flow and co-location and all sorts of unfair advantages possessed by a small handful of traders. All it needed was for investors to take responsibility for understanding it, and then to seize its controls. “The backbone of the market,” Katsuyama says, “is investors coming together to trade.”
  • If an investor as large as T. Rowe Price, which acted on behalf of millions of investors, had trouble obtaining the information it needed to determine if its brokers had acted in their interest, what chance did the little guy have?
  • The stock market really was rigged. Katsuyama often wondered how enterprising politicians and plaintiffs’ lawyers and state attorneys general would respond to that realization. (This March, the New York attorney general, Eric Schneiderman, announced a new investigation of the stock exchanges and the dark pools, and their relationships with high-frequency traders.

How Boys Teach Each Other to Be Boys - Noah Berlatsky - The Atlantic - 2 views

  • Judy Y. Chu reports on her two-year study in which she followed a group of boys from pre-kindergarten through first grade.
  • She concluded that most of what we think of as "boy" behavior isn't natural or authentic to boys, but is something they learn to perform. Boys aren't stoic or aggressive or hierarchical; they aren't bad at forming relationships or unable to express themselves. They pick up all these traditional traits of masculinity by adapting to a culture that expects and demands that they do so.
  • it seems like they become boys through learning from other boys; it's boys teaching themselves to be boys. So where do you see the inauthenticity or unnaturalness there?

  • It's not as though they're arriving in their interactions having come from an isolated place. They're hearing messages from older siblings, from media, or some of the boys' parents
  • They're creating a culture for themselves based on the bits and pieces they've gotten elsewhere.
  • it's more that distinction between compromise and over-compromise, in which they're so focused on setting up a particular image that they believe will get them what they want—acceptance and popularity and success—and realizing that that comes at a cost.
  • they need to have at least one place or one relationship where they can do those things.
  • when you take the whole range of human capabilities and qualities, and you say one half is masculine, and one half is feminine, and only boys can be masculine, and only girls can be feminine, then everybody loses, because you're asking e
  • we live in a culture and a society where we are perceived in our bodies, and people respond to us accordingly. So boys and girls do grow up in a gendered society
  • infant studies show us that both boys and girls are born with a capacity for and a fundamental desire for relationships—to be close and to be connected. And if anything they find that boy babies need more help regulating themselves. When they are upset they need their primary caregiver to help them regulate and come back to a feeling of contentment.
  • then at these later reports when they get to adolescence where boys are reporting fewer close relationships, lower levels of intimacy within their close relationships, then that kind of suggests that for boys, their socialization and development are associated with a move out of relationships. They start out wanting and thriving in relationships, and then they are moved away from those protective relationships, and there's a cost.
  • the single best protector during adolescence, against psychological risks like low self-esteem and depression, and against social risks like unintended pregnancy, was having access to at least one close, confiding relationship. And that could be with a parent or a mentor or a friend or a sibling or whoever. The kids who had at least one close relationship were protected against all of those risks, and were better off for it.

G.O.P. Theme in Fall Election: It's a Dark and Unsafe World - NYTimes.com - 0 views

  • With four weeks to go before the midterm elections, Republicans have made questions of how safe we are – from disease, terrorism or something unspoken and perhaps more ominous – central in their attacks against Democrats. Their message is decidedly grim: Mr. Obama and the Democratic Party run a government that is so fundamentally broken it cannot offer its people the most basic protection from harm.
  • Republicans believe they have found the sentiment that will tie Congressional races together with a single national theme.
  • When Republicans picked up seats in the House and Senate in 2010, they did so by running on burning emotional issues like unemployment and anger over the passage of the Affordable Care Act.

  • That lack of confidence in the government is a sentiment Republicans are trying to tether to Mr. Obama and the Democratic Party.
  • While anger and economic unease have subsided, polls suggest that people are anxious. A recent survey by The Associated Press found that 53 percent of Americans believe the risk of another terrorist attack inside the country is extremely high or very high. In a new Pew poll, 41 percent said they had “not too much confidence” or “no confidence at all” that the government could prevent a major Ebola outbreak in the United States.
  • Republicans said the hyperbole highlighted the perception that the president, with his no-drama air, often plays down the seriousness of the problems facing the country.

Multiple Colors Can Trick the Mind - NYTimes.com - 0 views

  • I heard that people can’t look at a color in one room and then pick it out of a set of similar colors in the next room. But there are people with perfect pitch, so are there people with “perfect hue”?

  • "Learning a language is a question of repeated high-quality exposure,"
  • "If a family reads a book to their child in Spanish as part of a bedtime routine, that's a lot of reading and a lot of learning over an extended period of time."
  • What you can expect: Results range from recognizing the language when it's spoken to being able to converse casually. The more time the child spends with the nanny or in bilingual daycare, the greater the proficiency. "It all depends on the amount and quality of the child's exposure,"
  • What you can expect: A bilingual tot, in time. Don't worry if he doesn't speak either language as adeptly as his monolingual peers at first. If your child is exposed to both languages the same amount, he will be able to speak both equally well by the time he goes to school.

    Language can help a child advance in school. This is an example of language not creating barriers, but actually helping a person.

How Media Bias Is Killing Black America - The Root - 0 views

  • leads to both the erasure and criminalization of marginalized communities, has had dire consequences for both the psyches and lived experiences of black people in the United States since at least the 18th century,
  • “This is the press, an irresponsible press,” he said. “It will make the criminal look like he’s the victim and make the victim look like he’s the criminal. If you aren’t careful, the newspapers will have you hating the people who are being oppressed and loving the people who are doing the oppressing.”
  • Many studies have tackled implicit racial bias in law enforcement, health care and the legal field.

  • “Implicit bias impacts the way black communities are treated across practically all sectors of life in America, from courtrooms to doctors’ offices,

  • “The percentage of minority journalists has remained between 12 and 14 percent for more than a decade.”
  • This lays the groundwork for an intrinsically racist media structure that, according to The Atlantic’s Riva Gold, means “news organizations are losing their ability to empower, represent, and—especially in cases where language ability is crucial—even to report on minority populations in their communities.”
