Gravity Probe B Project Confirms Einstein Space-Time Ideas - NYTimes.com - 0 views

  • Observations of planets, the Moon and particularly the shifting orbits of the Lageos research satellites had convinced astronomers and physicists that Einstein’s predictions were on the mark. Nevertheless, scientists said that the Gravity Probe results would live forever in textbooks as the most direct measurements, and that it was important to keep testing theories that were thought to be correct.
  • Empty space in the vicinity of Earth is indeed turning, Dr. Everitt reported at the news conference and in a paper prepared for the journal Physical Review Letters, at the leisurely rate of 37 one-thousandths of a second of arc — the equivalent of a human hair seen from 10 miles away — every year. With an uncertainty of 19 percent, that measurement was in agreement with Einstein’s predictions of 39 milliarcseconds.

  • path dependence. This refers to the notion that often “something that seems normal or inevitable today began with a choice that made sense at a particular time in the past, but survived despite the eclipse of the justification for that choice.
  • Einstellung Effect, the idea that we often try to solve problems by using solutions that worked in the past instead of looking at each situation on its own terms.
  • the Focusing Illusion, which holds that “nothing in life is as important as you think it is while you are thinking about it.”
  • Supervenience. Imagine a picture on a computer screen of a dog sitting in a rowboat. It can be described as a picture of a dog, but at a different level it can be described as an arrangement of pixels and colors. The relationship between the two levels is asymmetric. The same image can be displayed at different sizes with different pixels. The high-level properties (dogness) supervene the low-level properties (pixels).

  • We often try to understand problems by taking apart and studying their constituent parts. But emergent problems can’t be understood this way. Emergent systems are ones in which many different elements interact. The pattern of interaction then produces a new element that is greater than the sum of the parts, which then exercises a top-down influence on the constituent elements.

In Defense of Naïve Reading - NYTimes.com - 1 views

  • Clearly, poems and novels and paintings were not produced as objects for future academic study; there is no a priori reason to think that they could be suitable objects of  “research.” By and large they were produced for the pleasure and enlightenment of those who enjoyed them.
  • But just as clearly, the teaching of literature in universities ─ especially after the 19th-century research model of Humboldt University of Berlin was widely copied ─ needed a justification consistent with the aims of that academic setting
  • The main aim was research: the creating and accumulation and transmission of knowledge. And the main model was the natural science model of collaborative research: define problems, break them down into manageable parts, create sub-disciplines and sub-sub-disciplines for the study of these, train students for such research specialties and share everything. With that model, what literature and all the arts needed was something like a general “science of meaning” that could eventually fit that sort of aspiration. Texts or art works could be analyzed as exemplifying and so helping establish such a science. Results could be published in scholarly journals, disputed by others, consensus would eventually emerge and so on.

  • literature study in a university education requires some method of evaluation of whether the student has done well or poorly. Students’ papers must be graded and no faculty member wants to face the inevitable “that’s just your opinion” unarmed, as it were. Learning how to use a research methodology, providing evidence that one has understood and can apply such a method, is understandably an appealing pedagogy
  • Literature and the arts have a dimension unique in the academy, not shared by the objects studied, or “researched” by our scientific brethren. They invite or invoke, at a kind of “first level,” an aesthetic experience that is by its nature resistant to restatement in more formalized, theoretical or generalizing language. This response can certainly be enriched by knowledge of context and history, but the objects express a first-person or subjective view of human concerns that is falsified if wholly transposed to a more “sideways on” or third person view.
  • such works also can directly deliver a  kind of practical knowledge and self-understanding not available from a third person or more general formulation of such knowledge. There is no reason to think that such knowledge — exemplified in what Aristotle said about the practically wise man (the phronimos)or in what Pascal meant by the difference between l’esprit géometrique and l’esprit de finesse — is any less knowledge because it cannot be so formalized or even taught as such.

The Joy of Psyching Myself Out­ - The New York Times - 0 views

  • that neat separation is not just unwarranted; it’s destructive
  • Although it’s often presented as a dichotomy (the apparent subjectivity of the writer versus the seeming objectivity of the psychologist), it need not be.
  • IS it possible to think scientifically and creatively at once? Can you be both a psychologist and a writer?
  • ...10 more annotations...
  • “A writer must be as objective as a chemist,” Anton Chekhov wrote in 1887. “He must abandon the subjective line; he must know that dung heaps play a very reasonable part in a landscape.”
  • At the turn of the century, psychology was a field quite unlike what it is now. The theoretical musings of William James were the norm (a wry commenter once noted that William James was the writer, and his brother Henry, the psychologist)
  • Freud was a breed of psychologist that hardly exists anymore: someone who saw the world as both writer and psychologist, and for whom there was no conflict between the two. That boundary melding allowed him to posit the existence of cognitive mechanisms that wouldn’t be empirically proved for decades,
  • Freud got it brilliantly right and brilliantly wrong. The rightness is as good a justification as any of the benefits, the necessity even, of knowing how to look through the eyes of a writer. The wrongness is part of the reason that the distinction between writing and experimental psychology has grown far more rigid than it was a century ago.
  • the signs people associate with liars often have little empirical evidence to support them. Therein lies the psychologist’s distinct role and her necessity. As a writer, you look in order to describe, but you remain free to use that description however you see fit. As a psychologist, you look to describe, yes, but also to verify.
  • Without verification, we can’t always trust what we see — or rather, what we think we see.
  • The desire for the world to be what it ought to be and not what it is permeates experimental psychology as much as writing, though. There’s experimental bias and the problem known in the field as “demand characteristics” — when researchers end up finding what they want to find by cuing participants to act a certain way.
  • IN 1932, when he was in his 70s, Freud gave a series of lectures on psychoanalysis. In his final talk, “A Philosophy of Life,” he focused on clarifying an important caveat to his research: His followers should not be confused by the seemingly internal, and thus possibly subjective, nature of his work. “There is no other source of knowledge of the universe but the intellectual manipulation of carefully verified observations,” he said.
  • That is what both the psychologist and the writer should strive for: a self-knowledge that allows you to look in order to discover, without agenda, without preconception, without knowing or caring if what you’re seeing is wrong or right in your scheme of the world. It’s harder than it sounds. For one thing, you have to possess the self-knowledge that will allow you to admit when you’re wrong.
  • Even with the best intentions, objectivity can prove a difficult companion. I left psychology behind because I found its structural demands overly hampering. I couldn’t just pursue interesting lines of inquiry; I had to devise a set of experiments, see how feasible they were, both technically and financially, consider how they would reflect on my career. That meant that most new inquiries never happened — in a sense, it meant that objectivity was more an ideal than a reality. Each study was selected for a reason other than intrinsic interest.

Denying Genetics Isn't Shutting Down Racism, It's Fueling It - 0 views

  • For many on the academic and journalistic left, genetics are deemed largely irrelevant when it comes to humans. Our large brains and the societies we have constructed with them, many argue, swamp almost all genetic influences.
  • Humans, in this view, are the only species on Earth largely unaffected by recent (or ancient) evolution, the only species where, for example, the natural division of labor between male and female has no salience at all, the only species, in fact, where natural variations are almost entirely social constructions, subject to reinvention.
  • if we assume genetics play no role, and base our policy prescriptions on something untrue, we are likely to overshoot and over-promise in social policy, and see our rhetoric on race become ever more extreme and divisive.

  • Reich simply points out that this utopian fiction is in danger of collapse because it is not true and because genetic research is increasingly proving it untrue.
  • “You will sometimes hear that any biological differences among populations are likely to be small, because humans have diverged too recently from common ancestors for substantial differences to have arisen under the pressure of natural selection. This is not true. The ancestors of East Asians, Europeans, West Africans and Australians were, until recently, almost completely isolated from one another for 40,000 years or longer, which is more than sufficient time for the forces of evolution to work.” Which means to say that the differences could be (and actually are) substantial.
  • If you don’t establish a reasonable forum for debate on this, Reich argues, if you don’t establish the principle is that we do not have to be afraid of any of this, it will be monopolized by truly unreasonable and indeed dangerous racists. And those racists will have the added prestige for their followers of revealing forbidden knowledge.
  • so there are two arguments against the suppression of this truth and the stigmatization of its defenders: that it’s intellectually dishonest and politically counterproductive.
  • Klein seems to back a truly extreme position: that only the environment affects IQ scores, and genes play no part in group differences in human intelligence. To this end, he cites the “Flynn effect,” which does indeed show that IQ levels have increased over the years, and are environmentally malleable up to a point. In other words, culture, politics, and economics do matter.
  • But Klein does not address the crucial point that even with increases in IQ across all races over time, the racial gap is still frustratingly persistent, that, past a certain level, IQ measurements have actually begun to fall in many developed nations, and that Flynn himself acknowledges that the effect does not account for other genetic influences on intelligence.
  • In an email exchange with me, in which I sought clarification, Klein stopped short of denying genetic influences altogether, but argued that, given rising levels of IQ, and given how brutal the history of racism against African-Americans has been, we should nonetheless assume “right now” that genes are irrelevant.
  • My own brilliant conclusion: Group differences in IQ are indeed explicable through both environmental and genetic factors and we don’t yet know quite what the balance is.
  • We are, in this worldview, alone on the planet, born as blank slates, to be written on solely by culture. All differences between men and women are a function of this social effect; as are all differences between the races. If, in the aggregate, any differences in outcome between groups emerge, it is entirely because of oppression, patriarchy, white supremacy, etc. And it is a matter of great urgency that we use whatever power we have to combat these inequalities.
  • Liberalism has never promised equality of outcomes, merely equality of rights. It’s a procedural political philosophy rooted in means, not a substantive one justified by achieving certain ends.
  • A more nuanced understanding of race, genetics, and environment would temper this polarization, and allow for more unifying, practical efforts to improve equality of opportunity, while never guaranteeing or expecting equality of outcomes.
  • In some ways, this is just a replay of the broader liberal-conservative argument. Leftists tend to believe that all inequality is created; liberals tend to believe we can constantly improve the world in every generation, forever perfecting our societies.
  • Rightists believe that human nature is utterly unchanging; conservatives tend to see the world as less plastic than liberals, and attempts to remake it wholesale dangerous and often counterproductive.
  • I think the genius of the West lies in having all these strands in our politics competing with one another.
  • Where I do draw the line is the attempt to smear legitimate conservative ideas and serious scientific arguments as the equivalent of peddling white supremacy and bigotry. And Klein actively contributes to that stigmatization and demonization. He calls the science of this “race science” as if it were some kind of illicit and illegitimate activity, rather than simply “science.”
  • He goes on to equate the work of these scientists with the “most ancient justification for bigotry and racial inequality.” He even uses racism to dismiss Murray and Harris: they are, after all, “two white men.
  • He still refuses to believe that Murray’s views on this are perfectly within the academic mainstream in studies of intelligence, as they were in 1994.
  • Klein cannot seem to hold the following two thoughts in his brain at the same time: that past racism and sexism are foul, disgusting, and have wrought enormous damage and pain and that unavoidable natural differences between races and genders can still exist.
  • , it matters that we establish a liberalism that is immune to such genetic revelations, that can strive for equality of opportunity, and can affirm the moral and civic equality of every human being on the planet.
  • We may even embrace racial discrimination, as in affirmative action, that fuels deeper divides. All of which, it seems to me, is happening — and actively hampering racial progress, as the left defines the most multiracial and multicultural society in human history as simply “white supremacy” unchanged since slavery; and as the right viscerally responds by embracing increasingly racist white identity politics.
  • liberalism is integral to our future as a free society — and it should not falsely be made contingent on something that can be empirically disproven. It must allow for the truth of genetics to be embraced, while drawing the firmest of lines against any moral or political abuse of it

The Moral Instinct - The New York Times - 2 views

  • Today, a new field is using illusions to unmask a sixth sense, the moral sense. Moral intuitions are being drawn out of people in the lab, on Web sites and in brain scanners, and are being explained with tools from game theory, neuroscience and evolutionary biology.
  • The other hallmark is that people feel that those who commit immoral acts deserve to be punished
  • If morality is a mere trick of the brain, some may fear, our very grounds for being moral could be eroded. Yet as we shall see, the science of the moral sense can instead be seen as a way to strengthen those grounds, by clarifying what morality is and how it should steer our actions.
  • ...13 more annotations...
  • The starting point for appreciating that there is a distinctive part of our psychology for morality is seeing how moral judgments differ from other kinds of opinions we have on how people ought to behave.
  • Moralization is a psychological state that can be turned on and off like a switch, and when it is on, a distinctive mind-set commandeers our thinking. This is the mind-set that makes us deem actions immoral (“killing is wrong”), rather than merely disagreeable (“I hate brussels sprouts”), unfashionable (“bell-bottoms are out”) or imprudent (“don’t scratch mosquito bites”).
  • The first hallmark of moralization is that the rules it invokes are felt to be universal
  • Many of these moralizations, like the assault on smoking, may be understood as practical tactics to reduce some recently identified harm. But whether an activity flips our mental switches to the “moral” setting isn’t just a matter of how much harm it does
  • We all know what it feels like when the moralization switch flips inside us — the righteous glow, the burning dudgeon, the drive to recruit others to the cause.
  • The human moral sense turns out to be an organ of considerable complexity, with quirks that reflect its evolutionary history and its neurobiological foundations.
  • At the same time, many behaviors have been amoralized, switched from moral failings to lifestyle choices. They include divorce, illegitimacy, being a working mother, marijuana use and homosexuality.
  • This wave of amoralization has led the cultural right to lament that morality itself is under assault, as we see in the group that anointed itself the Moral Majority. In fact there seems to be a Law of Conservation of Moralization, so that as old behaviors are taken out of the moralized column, new ones are added to it.
  • Much of our recent social history, including the culture wars between liberals and conservatives, consists of the moralization or amoralization of particular kinds of behavior.
  • People don’t generally engage in moral reasoning, Haidt argues, but moral rationalization: they begin with the conclusion, coughed up by an unconscious emotion, and then work backward to a plausible justification.
  • When psychologists say “most people” they usually mean “most of the two dozen sophomores who filled out a questionnaire for beer money.” But in this case it means most of the 200,000 people from a hundred countries who shared their intuitions on a Web-based experiment conducted by the psychologists Fiery Cushman and Liane Young and the biologist Marc Hauser. A difference between the acceptability of switch-pulling and man-heaving, and an inability to justify the choice, was found in respondents from Europe, Asia and North and South America; among men and women, blacks and whites, teenagers and octogenarians, Hindus, Muslims, Buddhists, Christians, Jews and atheists; people with elementary-school educations and people with Ph.D.’s.
  • Joshua Greene, a philosopher and cognitive neuroscientist, suggests that evolution equipped people with a revulsion to manhandling an innocent person. This instinct, he suggests, tends to overwhelm any utilitarian calculus that would tot up the lives saved and lost
  • the findings corroborate Greene’s theory that our nonutilitarian intuitions come from the victory of an emotional impulse over a cost-benefit analysis.

Half Of The Jury In The Chauvin Trial Is Nonwhite. That's Only Part Of The Story : Live... - 0 views

  • Hennepin County, where the trial is being held, is only 17% Black or multiracial, while it is 74% white.
  • The jury's racial makeup will assuage some of the concerns that activists and others had expressed as jury selection got underway two weeks ago.
  • An insufficiently diverse jury, they believed, would undercut people's faith in the legitimacy of a trial seen as a critical moment in the racial justice movement that Floyd's killing helped reenergize last spring.
  • Two of the Black men on the jury are not African Americans but, rather, Black immigrants. During questioning, they expressed the kind of moderate views on policing and race relations
  • None of the Black jurors ultimately chosen for the panel spoke extensively about personal experiences with racism or about having had overtly negative interactions with police. Several said they had a healthy respect for law enforcement.
  • The fate of Juror 76 highlighted a tension that often exists in jury selection, especially in cases in which issues of race loom large. The experiences that come with being Black in America are often enough to get jurors struck from a case
  • That did not seem to be the case during jury selection for the Chauvin trial. Several jurors who expressed at least some support for the movement were seated on the jury — a sign of progress, Chakravarti said.
  • On one hand, that the defense would strike people with negative views of police is understandable, given Nelson's responsibility to seat a jury favorable to his client.
  • She said his fate was a reminder that the jury selection process should be reformed to ensure more African Americans have a fair shot to serve on juries."We should start," she wrote, "by recognizing that their lived experiences with racism are not justification to excuse them."

Opinion | Humans Are Animals. Let's Get Over It. - The New York Times - 0 views

  • The separation of people from, and the superiority of people to, members of other species is a good candidate for the originating idea of Western thought. And a good candidate for the worst.
  • Like Plato, Hobbes associates anarchy with animality and civilization with the state, which gives to our merely animal motion moral content for the first time and orders us into a definite hierarchy.
  • It is rationality that gives us dignity, that makes a claim to moral respect that no mere animal can deserve. “The moral law reveals to me a life independent of animality,” writes Immanuel Kant in “Critique of Practical Reason.” In this assertion, at least, the Western intellectual tradition has been remarkably consistent.
  • ...15 more annotations...
  • the devaluation of animals and disconnection of us from them reflect a deeper devaluation of the material universe in general
  • In this scheme of things, we owe nature nothing; it is to yield us everything. This is the ideology of species annihilation and environmental destruction, and also of technological development.
  • Further trouble is caused when the distinctions between humans and animals are then used to draw distinctions among human beings
  • Some of us, in short, are animals — and some of us are better than that. This, it turns out, is a useful justification for colonialism, slavery and racism.
  • The classical source for this distinction is certainly Aristotle. In the “Politics,” he writes, “Where then there is such a difference as that between soul and body, or between men and animals (as in the case of those whose business is to use their body, and who can do nothing better), the lower sort are by nature slaves.
  • Every human hierarchy, insofar as it can be justified philosophically, is treated by Aristotle by analogy to the relation of people to animals.
  • One difficult thing to face about our animality is that it entails our deaths; being an animal is associated throughout philosophy with dying purposelessly, and so with living meaninglessly.
  • this line of thought also happens to justify colonizing or even extirpating the “savage,” the beast in human form.
  • Our supposed fundamental distinction from “beasts, “brutes” and “savages” is used to divide us from nature, from one another and, finally, from ourselves
  • In Plato’s “Republic,” Socrates divides the human soul into two parts. The soul of the thirsty person, he says, “wishes for nothing else than to drink.” But we can restrain ourselves. “That which inhibits such actions,” he concludes, “arises from the calculations of reason.” When we restrain or control ourselves, Plato argues, a rational being restrains an animal.
  • In this view, each of us is both a beast and a person — and the point of human life is to constrain our desires with rationality and purify ourselves of animality
  • These sorts of systematic self-divisions come to be refigured in Cartesian dualism, which separates the mind from the body, or in Sigmund Freud’s distinction between id and ego, or in the neurological contrast between the functions of the amygdala and the prefrontal cortex.
  • I don’t know how to refute it, exactly, except to say that I don’t feel myself to be a logic program running on an animal body; I’d like to consider myself a lot more integrated than that.
  • And I’d like to repudiate every political and environmental conclusion ever drawn by our supposed transcendence of the order of nature
  • There is no doubt that human beings are distinct from other animals, though not necessarily more distinct than other animals are from one another. But maybe we’ve been too focused on the differences for too long. Maybe we should emphasize what all us animals have in common.

Opinion | Why Covid's Airborne Transmission Was Acknowledged So Late - The New York Times - 0 views

  • A week ago, more than a year after the World Health Organization declared that we face a pandemic, a page on its website titled “Coronavirus Disease (Covid-19): How Is It Transmitted?” got a seemingly small update.
  • The revised response still emphasizes transmission in close contact but now says it may be via aerosols — smaller respiratory particles that can float — as well as droplets. It also adds a reason the virus can also be transmitted “in poorly ventilated and/or crowded indoor settings,” saying this is because “aerosols remain suspended in the air or travel farther than 1 meter.”
  • on Friday, the Centers for Disease Control and Prevention also updated its guidance on Covid-19, clearly saying that inhalation of these smaller particles is a key way the virus is transmitted, even at close range, and put it on top of its list of how the disease spreads.
  • ...38 more annotations...
  • But these latest shifts challenge key infection control assumptions that go back a century, putting a lot of what went wrong last year in context
  • They may also signal one of the most important advancements in public health during this pandemic.
  • If the importance of aerosol transmission had been accepted early, we would have been told from the beginning that it was much safer outdoors, where these small particles disperse more easily, as long as you avoid close, prolonged contact with others.
  • We would have tried to make sure indoor spaces were well ventilated, with air filtered as necessary.
  • Instead of blanket rules on gatherings, we would have targeted conditions that can produce superspreading events: people in poorly ventilated indoor spaces, especially if engaged over time in activities that increase aerosol production, like shouting and singing
  • We would have started using masks more quickly, and we would have paid more attention to their fit, too. And we would have been less obsessed with cleaning surfaces.
  • The implications of this were illustrated when I visited New York City in late April — my first trip there in more than a year.
  • A giant digital billboard greeted me at Times Square, with the message “Protecting yourself and others from Covid-19. Guidance from the World Health Organization.”
  • That billboard neglected the clearest epidemiological pattern of this pandemic: The vast majority of transmission has been indoors, sometimes beyond a range of three or even six feet. The superspreading events that play a major role in driving the pandemic occur overwhelmingly, if not exclusively, indoors.
  • The billboard had not a word about ventilation, nothing about opening windows or moving activities outdoors, where transmission has been rare and usually only during prolonged and close contact. (Ireland recently reported 0.1 percent of Covid-19 cases were traced to outdoor transmission.)
  • Mary-Louise McLaws, an epidemiologist at the University of New South Wales in Sydney, Australia, and a member of the W.H.O. committees that craft infection prevention and control guidance, wanted all this examined but knew the stakes made it harder to overcome the resistance. She told The Times last year, “If we started revisiting airflow, we would have to be prepared to change a lot of what we do.” She said it was a very good idea, but she added, “It will cause an enormous shudder through the infection control society.”
  • In contrast, if the aerosols had been considered a major form of transmission, in addition to distancing and masks, advice would have centered on ventilation and airflow, as well as time spent indoors. Small particles can accumulate in enclosed spaces, since they can remain suspended in the air and travel along air currents. This means that indoors, three or even six feet, while helpful, is not completely protective, especially over time.
  • To see this misunderstanding in action, look at what’s still happening throughout the world. In India, where hospitals have run out of supplemental oxygen and people are dying in the streets, money is being spent on fleets of drones to spray anti-coronavirus disinfectant in outdoor spaces. Parks, beaches and outdoor areas keep getting closed around the world. This year and last, organizers canceled outdoor events for the National Cherry Blossom Festival in Washington, D.C. Cambodian customs officials advised spraying disinfectant outside vehicles imported from India. The examples are many.
  • Meanwhile, many countries allowed their indoor workplaces to open but with inadequate aerosol protections. There was no attention to ventilation, installing air filters as necessary or even opening windows when possible, more to having people just distancing three or six feet, sometimes not requiring masks beyond that distance, or spending money on hard plastic barriers, which may be useless at best
  • clear evidence doesn’t easily overturn tradition or overcome entrenched feelings and egos. John Snow, often credited as the first scientific epidemiologist, showed that a contaminated well was responsible for a 1854 London cholera epidemic by removing the suspected pump’s handle and documenting how the cases plummeted afterward. Many other scientists and officials wouldn’t believe him for 12 years, when the link to a water source showed up again and became harder to deny.
  • Along the way to modern public health shaped largely by the fight over germs, a theory of transmission promoted by the influential public health figure Charles Chapin took hold
  • Dr. Chapin asserted in the early 1900s that respiratory diseases were most likely spread at close range by people touching bodily fluids or ejecting respiratory droplets, and did not allow for the possibility that such close-range infection could occur by inhaling small floating particles others emitted
  • He was also concerned that belief in airborne transmission, which he associated with miasma theories, would make people feel helpless and drop their guard against contact transmission. This was a mistake that would haunt infection control for the next century and more.
  • It was in this context in early 2020 that the W.H.O. and the C.D.C. asserted that SARS-CoV-2 was transmitted primarily via these heavier, short-range droplets, and provided guidance accordingly
  • Amid the growing evidence, in July, hundreds of scientists signed an open letter urging the public health agencies, especially the W.H.O., to address airborne transmission of the coronavirus.
  • Last October, the C.D.C. published updated guidance acknowledging airborne transmission, but as a secondary route under some circumstances, until it acknowledged airborne transmission as crucial on Friday. And the W.H.O. kept inching forward in its public statements, most recently a week ago.
  • Linsey Marr, a professor of engineering at Virginia Tech who made important contributions to our understanding of airborne virus transmission before the pandemic, pointed to two key scientific errors — rooted in a lot of history — that explain the resistance, and also opened a fascinating sociological window into how science can get it wrong and why.
  • Dr. Marr said that if you inhale a particle from the air, it’s an aerosol.
  • biomechanically, she said, nasal transmission faces obstacles, since nostrils point downward and the physics of particles that large makes it difficult for them to move up the nose. And in lab measurements, people emit far more of the easier-to-inhale aerosols than the droplets, she said, and even the smallest particles can be virus laden, sometimes more so than the larger ones, seemingly because of how and where they are produced in the respiratory tract.
  • Second, she said, proximity is conducive to transmission of aerosols as well because aerosols are more concentrated near the person emitting them. In a twist of history, modern scientists have been acting like those who equated stinky air with disease, by equating close contact, a measure of distance, only with the larger droplets, a mechanism of transmission, without examination.
  • Since aerosols also infect at close range, measures to prevent droplet transmission — masks and distancing — can help dampen transmission for airborne diseases as well. However, this oversight led medical people to circularly assume that if such measures worked at all, droplets must have played a big role in their transmission.
  • Another dynamic we’ve seen is something that is not unheard-of in the history of science: setting a higher standard of proof for theories that challenge conventional wisdom than for those that support it.
  • Another key problem is that, understandably, we find it harder to walk things back. It is easier to keep adding exceptions and justifications to a belief than to admit that a challenger has a better explanation.
  • The ancients believed that all celestial objects revolved around the earth in circular orbits. When it became clear that the observed behavior of the celestial objects did not fit this assumption, those astronomers produced ever-more-complex charts by adding epicycles — intersecting arcs and circles — to fit the heavens to their beliefs.
  • In a contemporary example of this attitude, the initial public health report on the Mount Vernon choir case said that it may have been caused by people “sitting close to one another, sharing snacks and stacking chairs at the end of the practice,” even though almost 90 percent of the people there developed symptoms of Covid-19
  • So much of what we have done throughout the pandemic — the excessive hygiene theater and the failure to integrate ventilation and filters into our basic advice — has greatly hampered our response.
  • Some of it, like the way we underused or even shut down outdoor space, isn’t that different from the 19th-century Londoners who flushed the source of their foul air into the Thames and made the cholera epidemic worse.
  • Righting this ship cannot be a quiet process — updating a web page here, saying the right thing there. The proclamations that we now know are wrong were so persistent and so loud for so long.
  • the progress we’ve made might lead to an overhaul in our understanding of many other transmissible respiratory diseases that take a terrible toll around the world each year and could easily cause other pandemics.
  • So big proclamations require probably even bigger proclamations to correct, or the information void, unnecessary fears and misinformation will persist, damaging the W.H.O. now and in the future.

  • The W.H.O. needs to address these fears and concerns, treating it as a matter of profound change, so other public health agencies and governments, as well as ordinary people, can better adjust.
  • It needs to begin a campaign proportional to the importance of all this, announcing, “We’ve learned more, and here’s what’s changed, and here’s how we can make sure everyone understands how important this is.” That’s what credible leadership looks like.

America Is Flunking Math - Persuasion - 1 views

  • One can argue that the preeminence of each civilization was, in part, due to their sophisticated understanding and use of mathematics. This is particularly clear in the case of the West, which forged ahead in the 17th century with the discovery of calculus, one of the greatest scientific breakthroughs of all time.
  • The United States became the dominant force in the mathematical sciences in the wake of World War II, largely due to the disastrous genocidal policies of the Third Reich. The Nazis’ obsession with purging German science of what it viewed as nefarious Jewish influence led to a massive exodus of Jewish mathematicians and scientists to America
  • Indeed, academic institutions in the United States have thrived largely because of their ability to attract talented individuals from around the world.
  • ...28 more annotations...
  • The quality of mathematics research in the United States today is the envy of the scientific world. This is a direct result of the openness and inclusivity of the profession.
  • Can Americans maintain this unmatched excellence in the future? There are worrisome signs that suggest not.
  • The Organization for Economic Cooperation and Development compares mathematical proficiency among 15-year-olds by country worldwide. According to its 2018 report, America ranked 37th while China, America’s main competitor for world leadership, came in first.
  • This is despite the fact that the United States is the fifth-highest spender per pupil among the 37 developed OECD nations
  • This massive failure of our K-12 education system trickles through the STEM pipeline.
  • At the undergraduate level, too few American students are prepared for higher-level mathematics courses. These students are then unprepared for rigorous graduate-level work
  • According to our own experiences at the universities where we teach, an overwhelming majority of American students with strong math backgrounds are either foreign-born or first-generation students who have additional support from their education-conscious families. At all levels, STEM disciplines are more and more dependent on a constant flow of foreign talent.
  • There are many reasons for this failure, but the way that we educate and prepare teachers is particularly influential. The vast majority of K-12 math teachers are graduates of teacher-preparation programs that teach very little substantive mathematics
  • This has led to a constant stream of ill-advised and dumbed-down reforms. One of the latest fads is anti-racist mathematics. Promoted in several states, the bizarre doctrine threatens to further degrade the teaching of mathematics.
  • Another major concern is the twisted interpretation of diversity, equity, and inclusion (DEI).
  • Under the banner of DEI, universities are abandoning the use of standardized tests like the SAT and GRE in admissions, and cities are considering scrapping academic tracking and various gifted programs in schools, which they deem “inequitable.”
  • such programs are particularly effective, when properly implemented, at discovering and encouraging talented children from disadvantaged backgrounds.
  • The new 2021 Mathematics Framework, currently under consideration by California’s Department of Education, does away “with all tracking, acceleration, gifted programs, or any instruction that involves clustering by individual differences, without expressing any awareness of the impact these drastic alterations would have in preparing STEM-ready candidates.”
  • These measures will not only hinder the progress of the generations of our future STEM workforce but also contribute to structural inequalities, as they are uniquely detrimental to students whose parents cannot send them to private schools or effective enrichment programs.
  • These are just a few examples of an unprecedented fervor for revolutionary change in the name of Critical Race Theory (CRT), a doctrine that views the world as a fierce battleground for the narratives of various identity groups.
  • This will only lead to a further widening of racial disparities in educational outcomes while lowering American children’s rankings in education internationally.
  • Ill-conceived DEI policies, often informed by CRT, and the declining standards of K-12 math education feed each other in a vicious circle
  • Regarding minorities, in particular, public K-12 education all too often produces students unprepared to compete, thus leading to large disparities in admissions at universities, graduate programs, and faculty positions. This disparity is then condemned as a manifestation of structural racism, resulting in administrative measures to lower the evaluation criteria. Lowering standards at all levels leads eventually to even worse outcomes and larger disparities, and so on in a downward spiral.
  • A case in point is the recent report by the American Mathematical Society that accuses the entire mathematics community, with the thinnest of specific evidence, of systemic racial discrimination. A major justification put forward for such a grave accusation is the lack of sufficient representation of Black mathematicians in the professio
  • the report, while raising awareness of several ugly facts from the long-ago past, makes little effort to address the real reasons for this, mainly the catastrophic failure of the K-12 mathematical educational system.
  • The National Science Foundation, a federal institution meant to support fundamental research, is now diverting some of its limited funding to various DEI initiatives of questionable benefit.
  • Meanwhile, other countries, especially China, are doing precisely the opposite, following the model of our past dedication to objective measures of excellence. How long before we will see a reverse exodus, away from the United States?
  • The present crisis can still be reversed by focusing on a few concrete actions:
  • Improve schools in urban areas and inner-city neighborhoods by following the most promising education programs. These programs demonstrate that inner-city children benefit if they are challenged by high standards and a nurturing environment.
  • Follow the lead of other highly successful rigorous programs such as BASIS schools and Math for America, which focus on rigorous STEM curricula, combined with 21st-century teaching methods, and recruit talented teachers to help them build on their STEM knowledge and teaching methods.
  • Increase, rather than eliminate, tailored instruction, both for accelerated and remedial math courses.
  • Reject the soft bigotry of low expectations, that Black children cannot do well in competitive mathematics programs and need dumbed-down ethnocentric versions of mathematics.
  • Uphold the objective selection process based on merit at all levels of education and research.

Thomas Kuhn Paradigm Shift | Simply Psychology - 0 views

  • Thomas Kuhn argued that science does not evolve gradually towards truth.
  • Science has a paradigm which remains constant before going through a paradigm shift when current theories can’t explain some phenomenon, and someone proposes a new theory.
  • A scientific revolution occurs when: (i) the new paradigm better explains the observations, and offers a model that is closer to the objective, external reality; and (ii) the new paradigm is incommensurate with the old.
  • ...23 more annotations...
  • Kuhn looked at the history of science and argued that science does not simply progress by stages based upon neutral observations
  • For Kuhn, the history of science is characterized by revolutions in scientific outlook. Scientists have a worldview or "paradigm"
  • A paradigm is a universally recognizable scientific achievement that, for a time, provides model problems and solutions to a community of practitioners.
  • Scientists accept the dominant paradigm until anomalies are thrown up.  Scientists then begin to question the basis of the paradigm itself, new theories emerge which challenge the dominant paradigm and eventually one of these new theories becomes accepted as the new paradigm.
  • A particular work may “define the legitimate problems and methods of a research field for succeeding generations of practitioners.”
  • This is where the paradigm shift occurs.
  • The pre-paradigmatic state refers to a period before a scientific consensus has been reached.
  • Phase 2: Normal Science
  • A paradigm is established which lays the foundations for legitimate work within the discipline. Scientific work then consists in articulation of the paradigm, in solving puzzles that it throws up.
  • It is necessary for normal science to be uncritical. If all scientists were critical of a theory and spent time trying to falsify it, no detailed work would ever get done.
  • Phase 1: Pre-sciencePhase 1: Pre-science
  • Phase 3: Crisis
  • "Normal Science, the activity in which most scientists inevitably spend almost all of their time, is predicated on the assumption that the scientific community knows what the world is like
  • Anomalies become serious, and a crisis develops if the anomalies undermine the basic assumptions of the paradigm and attempts to remove them consistently fail
  • If the anomalies can be resolved, the crisis is over and normal science resumes. If not, there is a scientific revolution which involves a change of paradigm.
  • Revoluti
  • Phase 4: Revolution
  • Eventually a new paradigm will be established, but not as a result of any logically compelling justification.
  • The enormous impact of Thomas Kuhn's work can be measured in the changes it brought about in the vocabulary of the philosophy of science: besides "paradigm shift", Kuhn raised the word "paradigm" itself from a term used in certain forms of linguistics to its current broader meaning.
  • For Kuhn, the choice of paradigm was sustained by, but not ultimately determined by, logical processes.
  • Kuhn believed that it represented the consensus of the community of scientists
  • Successive paradigms are incommensurable. Kuhn says that a later paradigm may be a better instrument for solving puzzles than an earlier one.  But if each paradigm defines its own puzzles, what is a puzzle for one paradigm may be no puzzle at all for another
  • Science does not change its paradigm over night. Younger scientists take a new paradigm forward

Why Study History? (1985) | AHA - 0 views

  • Isn't there quite enough to learn about the world today? Why add to the burden by looking at the past
  • Historical knowledge is no more and no less than carefully and critically constructed collective memory. As such it can both make us wiser in our public choices and more richly human in our private lives.
  • Without individual memory, a person literally loses his or her identity, and would not know how to act in encounters with others. Imagine waking up one morning unable to tell total strangers from family and friends!
  • ...37 more annotations...
  • Collective memory is similar, though its loss does not immediately paralyze everyday private activity. But ignorance of history-that is, absent or defective collective memory-does deprive us of the best available guide for public action, especially in encounters with outsider
  • Often it is enough for experts to know about outsiders, if their advice is listened to. But democratic citizenship and effective participation in the determination of public policy require citizens to share a collective memory, organized into historical knowledge and belief
  • This value of historical knowledge obviously justifies teaching and learning about what happened in recent times, for the way things are descends from the way they were yesterday and the day before that
  • in fact, institutions that govern a great deal of our everyday behavior took shape hundreds or even thousands of years ago
  • Only an acquaintance with the entire human adventure on earth allows us to understand these dimensions of contemporary reality.
  • it follows that study of history is essential for every young person.
  • Collective memory is quite the same. Historians are always at work reinterpreting the past, asking new questions, searching new sources and finding new meanings in old documents in order to bring the perspective of new knowledge and experience to bear on the task of understanding the past.
  • what we know and believe about history is always changing. In other words, our collective, codified memory alters with time just as personal memories do, and for the same reasons.
  • skeptics are likely to conclude that history has no right to take student time from other subjects. If what is taught today is not really true, how can it claim space in a crowded school curriculum?
  • what if the world is more complicated and diverse than words can ever tell? What if human minds are incapable of finding' neat pigeon holes into which everything that happens will fit?
  • What if we have to learn to live with uncertainty and probabilities, and act on the basis of the best guesswork we are capable of?
  • Then, surely, the changing perspectives of historical understanding are the very best introduction we can have to the practical problems of real life. Then, surely, a serious effort to understand the interplay of change and continuity in human affairs is the only adequate introduction human beings can have to the confusing flow of events that constitutes the actual, adult world.
  • Memory is not something fixed and forever. As time passes, remembered personal experiences take on new meanings.
  • Early in this century, teachers and academic administrators pretty well agreed that two sorts of history courses were needed: a survey of the national history of the United States and a survey of European history.
  • Memory, indeed, makes us human. History, our collective memory, carefully codified and critically revised, makes us social, sharing ideas and ideals with others so as to form all sorts of different human groups
  • The varieties of history are enormous; facts and probabilities about the past are far too numerous for anyone to comprehend them all. Every sort of human group has its own histor
  • Where to start? How bring some sort of order to the enormous variety of things known and believed about the past?
  • Systematic sciences are not enough. They discount time, and therefore oversimplify reality, especially human reality.
  • This second course was often broadened into a survey of Western civilization in the 1930s and 1940s
  • But by the 1960s and 1970s these courses were becoming outdated, left behind by the rise of new kinds social and quantitative history, especially the history of women, of Blacks, and of other formerly overlooked groups within the borders of the United States, and of peoples emerging from colonial status in the world beyond our borders.
  • much harder to combine old with new to make an inclusive, judiciously balanced (and far less novel) introductory course for high school or college students.
  • But abandoning the effort to present a meaningful portrait of the entire national and civilizational past destroyed the original justification for requiring students to study history
  • Competing subjects abounded, and no one could or would decide what mattered most and should take precedence. As this happened, studying history became only one among many possible ways of spending time in school.
  • The costs of this change are now becoming apparent, and many concerned persons agree that returning to a more structured curriculum, in which history ought to play a prominent part, is imperative.
  • three levels of generality seem likely to have the greatest importance for ordinary people.
  • First is family, local, neighborhood history
  • Second is national history, because that is where political power is concentrated in our time.
  • Last is global history, because intensified communications make encounters with all the other peoples of the earth increasingly important.
  • Other pasts are certainly worth attention, but are better studied in the context of a prior acquaintance with personal-local, national, and global history. That is because these three levels are the ones that affect most powerfully what all other groups and segments of society actually do.
  • National history that leaves out Blacks and women and other minorities is no longer acceptable; but American history that leaves out the Founding Fathers and the Constitution is not acceptable either. What is needed is a vision of the whole, warts and all.
  • the study of history does not lead to exact prediction of future events. Though it fosters practical wisdom, knowledge of the past does not permit anyone to know exactly what is going to happen
  • Consequently, the lessons of history, though supremely valuable when wisely formulated, become grossly misleading when oversimplifiers try to transfer them mechanically from one age to another, or from one place to another.
  • Predictable fixity is simply not the human way of behaving. Probabilities and possibilities-together with a few complete surprises-are what we live with and must learn to expect.
  • Second, as acquaintance with the past expands, delight in knowing more and more can and often does become an end in itself.
  • On the other hand, studying alien religious beliefs, strange customs, diverse family patterns and vanished social structures shows how differently various human groups have tried to cop
  • Broadening our humanity and extending our sensibilities by recognizing sameness and difference throughout the recorded past is therefore an important reason for studying history, and especially the history of peoples far away and long ago
  • For we can only know ourselves by knowing how we resemble and how we differ from others. Acquaintance with the human past is the only way to such self knowledge.

How to Get It Wrong - NYTimes.com - 2 views

  • economics needs rethinking in the wake of a disastrous crisis, a crisis that was neither predicted nor prevented.
  • it’s important to realize that the enormous intellectual failure of recent years took place at several levels. Clearly, economics as a discipline went badly astray in the years — actually decades — leading up to the crisis. But the failings of economics were greatly aggravated by the sins of economists, who far too often let partisanship or personal self-aggrandizement trump their professionalism. Last but not least, economic policy makers systematically chose to hear only what they wanted to hear. And it is this multilevel failure — not the inadequacy of economics alone — that accounts for the terrible performance of Western economies since 2008.
  • Hardly anyone predicted the 2008 crisis, but that in itself is arguably excusable in a complicated world.
  • ...8 more annotations...
  • More damning was the widespread conviction among economists that such a crisis couldn’t happen. Underlying this complacency was the dominance of an idealized vision of capitalism, in which individuals are always rational and markets always function perfectly.
  • In what sense did economics go astray?
  • But would it have mattered if economists had behaved better? Or would people in power have done the same thing regardless?
  • assuming away irrationality and market failure meant assuming away the very possibility of the kind of catastrophe that overtook the developed world six years ago.
  • while economic models didn’t perform all that badly after the crisis, all too many influential economists did — refusing to acknowledge error, letting naked partisanship trump analysis, or both.
  • starting in the 1980s it became harder and harder to publish anything questioning these idealized models in major journals. Economists trying to take account of imperfect reality faced what Harvard’s Kenneth Rogoff, hardly a radical figure (and someone I’ve sparred with) once called “new neoclassical repression.”
  • If you imagine that policy makers have spent the past five or six years in thrall to economic orthodoxy, you’ve been misled. On the contrary, key decision makers have been highly receptive to innovative, unorthodox economic ideas — ideas that also happen to be wrong but which offered excuses to do what these decision makers wanted to do anyway.
  • The great majority of policy-oriented economists believe that increasing government spending in a depressed economy creates jobs, and that slashing it destroys jobs — but European leaders and U.S. Republicans decided to believe the handful of economists asserting the opposite. Neither theory nor history justifies panic over current levels of government debt, but politicians decided to panic anyway, citing unvetted (and, it turned out, flawed) research as justification.

Bringing genetics into trans identity is a terrifying path | Fury | Opinion | The Guardian - 0 views

Trump's rebuke of Fauci encapsulates rejection of science in virus fight - CNNPolitics - 0 views

  • Trump broke with Fauci, who has served under six presidents, on Wednesday over the infectious disease expert's warnings that getting businesses and schools back open too quickly would lead to unnecessary suffering and death.
  • The delicate dynamic between Fauci and Trump has been watched for months. Its latest fraying marks the most pronounced clash yet in the tussle between science and politics that has long plagued the administration's fight against the coronavirus.
  • He has yet to initiate a serious national conversation about the vital need to get the economy firing again balanced against the level of death and illness that is acceptable to the country given that the pandemic could worsen if states open up too quickly.
  • ...6 more annotations...
  • Ironically, another of Trump's failings, one in which Fauci may be in some ways complicit as a member of the coronavirus task force -- to stand up a comprehensive national testing and tracking system -- may frustrate the President's effort to get the country up and running quickly with no vaccine in sight.
  • The gulf between Trump's approach and scientific rationality is expected to be further underscored Thursday with House testimony from Dr. Rick Bright, who says he was ousted from his job developing a coronavirus vaccine because he questioned Trump's enthusiasm for hydroxychloroquine, an unproven treatment for Covid-19. Bright will warn, according to his prepared testimony, that the US could face "unprecedented illness" and the "darkest winter in modern history" if it doesn't do a better job of preparing for a second wave of the pandemic.
  • Trump's use of the world "acceptable" in relation to Fauci's comments is instructive about how he sees subordinates in his administration. The history of his three years in power shows that officials who do not provide the justification and the pretext for his actions or who prefer to act on their own perceptions of the national interest are eventually ousted.
  • In recent weeks, Trump has shifted from an approach rooted in benchmarks for phased state openings based on a waning of the virus to one based on opening the economy whatever the cost.
  • Rising attacks on Fauci have taken their toll on his standing with the President's supporters, even though he is warmly regarded by the rest of the country. In a new CNN/SSRS poll, 84% of Republicans say they trust Trump to give them information on the virus. Only 61% of the same slice of the electorate say they trust Fauci, who has headed the National Institute of Allergy and Infectious Diseases since 1984.
  • "I'm a scientist, a physician and a public health official. I give advice, according to the best scientific evidence," he said. "I don't give advice about economic things."

Coronavirus: China to boost mass surveillance machine, experts say - 0 views

  • China could use the coronavirus outbreak to boost its mass surveillance capabilities as it looks to technology to help contain the epidemic in the world’s second-largest economy.The Communist Party has built a vast surveillance state through different methods with technology at its core.As artificial intelligence and the use of data becomes more advanced, Beijing has found increasingly effective ways to track the Chinese population, including facial recognition.
  • With over 77,000 coronavirus cases confirmed in China alone, the government has mobilized its surveillance machine, a move experts said could continue even after the virus has been contained.
  • The Chinese government has also enlisted the help of tech giants like Tencent, owner of popular messaging app WeChat and Alibaba subsidiary, Ant Financial, which runs payments app Alipay. On both WeChat and Alipay, users can put in their Chinese ID numbers and where they have travelled. Users will then be assigned a QR code based on a traffic light color system which instructs them about how long they need to be in quarantine, or whether they are free to travel. A QR code is a type of barcode which is widely used on digital platforms in China.

  • “Once these systems are in place, those involved in its developments — particularly companies with money to be made — argue for their expansion or their wider use, a phenomenon known as ‘mission creep.’ What initially started as a system to crack down on crime — which is already a dubious and vague enough justification to encompass political crimes in China — is now used for other purposes including for fighting the coronavirus outbreak.”

Do You Use Only 10% of Your Brain? | Mental Floss - 0 views

  • We may be biased, but we think the human brain is pretty special.
  • This myth is so prevalent that it is unquestioningly accepted as a pivotal plot point in movies, a motivational tactic for self-improvement, or justification for claims about ESP and other supposed untapped abilities of the human mind. A 2013 poll surveying over 2000 Americans found that 65 percent believed the 10 percent myth. A 2007 study in the British Medical Journal (BMJ) found that even some doctors weren't immune to the fallacy. But the truth is that everyone uses 100 percent of their brain.
  • Decades later, the myth has persevered because of the attractive possibility it seems to present. It absolves us for not reaching our full potential, offers a persistent insecurity for self-help gurus to appeal to, and provides a pseudo-scientific explanation for the limits of human comprehension.
