What Does Quantum Physics Actually Tell Us About the World? - The New York Times - 2 views

quantum physics theory reality science ontological

shared by Javier E on 11 May 18 - No Cached
  • The physics of atoms and their ever-smaller constituents and cousins is, as Adam Becker reminds us more than once in his new book, “What Is Real?,” “the most successful theory in all of science.” Its predictions are stunningly accurate, and its power to grasp the unseen ultramicroscopic world has brought us modern marvels.
  • But there is a problem: Quantum theory is, in a profound way, weird. It defies our common-sense intuition about what things are and what they can do.
  • Indeed, Heisenberg said that quantum particles “are not as real; they form a world of potentialities or possibilities rather than one of things or facts.”
  • ...19 more annotations...
  • Before he died, Richard Feynman, who understood quantum theory as well as anyone, said, “I still get nervous with it...I cannot define the real problem, therefore I suspect there’s no real problem, but I’m not sure there’s no real problem.” The problem is not with using the theory — making calculations, applying it to engineering tasks — but in understanding what it means. What does it tell us about the world?
  • From one point of view, quantum physics is just a set of formalisms, a useful tool kit. Want to make better lasers or transistors or television sets? The Schrödinger equation is your friend. The trouble starts only when you step back and ask whether the entities implied by the equation can really exist. Then you encounter problems that can be described in several familiar ways:
  • Wave-particle duality. Everything there is — all matter and energy, all known forces — behaves sometimes like waves, smooth and continuous, and sometimes like particles, rat-a-tat-tat. Electricity flows through wires, like a fluid, or flies through a vacuum as a volley of individual electrons. Can it be both things at once?
  • The uncertainty principle. Werner Heisenberg famously discovered that when you measure the position (let’s say) of an electron as precisely as you can, you find yourself more and more in the dark about its momentum. And vice versa. You can pin down one or the other but not both.
  • The measurement problem. Most of quantum mechanics deals with probabilities rather than certainties. A particle has a probability of appearing in a certain place. An unstable atom has a probability of decaying at a certain instant. But when a physicist goes into the laboratory and performs an experiment, there is a definite outcome. The act of measurement — observation, by someone or something — becomes an inextricable part of the theory
  • The strange implication is that the reality of the quantum world remains amorphous or indefinite until scientists start measuring
  • Other interpretations rely on “hidden variables” to account for quantities presumed to exist behind the curtain.
  • This is disturbing to philosophers as well as physicists. It led Einstein to say in 1952, “The theory reminds me a little of the system of delusions of an exceedingly intelligent paranoiac.”
  • “Figuring out what quantum physics is saying about the world has been hard,” Becker says, and this understatement motivates his book, a thorough, illuminating exploration of the most consequential controversy raging in modern science.
  • In a way, the Copenhagen is an anti-interpretation. “It is wrong to think that the task of physics is to find out how nature is,” Bohr said. “Physics concerns what we can say about nature.”
  • Nothing is definite in Bohr’s quantum world until someone observes it. Physics can help us order experience but should not be expected to provide a complete picture of reality. The popular four-word summary of the Copenhagen interpretation is: “Shut up and calculate!”
  • Becker sides with the worriers. He leads us through an impressive account of the rise of competing interpretations, grounding them in the human stories
  • He makes a convincing case that it’s wrong to imagine the Copenhagen interpretation as a single official or even coherent statement. It is, he suggests, a “strange assemblage of claims.
  • An American physicist, David Bohm, devised a radical alternative at midcentury, visualizing “pilot waves” that guide every particle, an attempt to eliminate the wave-particle duality.
  • Competing approaches to quantum foundations are called “interpretations,” and nowadays there are many. The first and still possibly foremost of these is the so-called Copenhagen interpretation.
  • Perhaps the most popular lately — certainly the most talked about — is the “many-worlds interpretation”: Every quantum event is a fork in the road, and one way to escape the difficulties is to imagine, mathematically speaking, that each fork creates a new universe
  • if you think the many-worlds idea is easily dismissed, plenty of physicists will beg to differ. They will tell you that it could explain, for example, why quantum computers (which admittedly don’t yet quite exist) could be so powerful: They would delegate the work to their alter egos in other universes.
  • When scientists search for meaning in quantum physics, they may be straying into a no-man’s-land between philosophy and religion. But they can’t help themselves. They’re only human.
  • If you were to watch me by day, you would see me sitting at my desk solving Schrödinger’s equation...exactly like my colleagues,” says Sir Anthony Leggett, a Nobel Prize winner and pioneer in superfluidity. “But occasionally at night, when the full moon is bright, I do what in the physics community is the intellectual equivalent of turning into a werewolf: I question whether quantum mechanics is the complete and ultimate truth about the physical universe.”

  • Last words such as these are only found in 14% of cases. The authors began to notice differences between note leavers and non-leavers in their research, as well as people who attempt suicide and those who complete the act.
  • Many notes were addressed to one person. Others were to no one in particular.
  • Nowadays, being a white male is the single biggest risk factor. Why is that? According to Case and Deaton, drastic changes in the labor market is the most significant factor.
  • “Hegemonic masculinity,” or a perception that heightened masculinity must be portrayed at all times, a goal that no male can live up to.
  • Another 23% of note writers ended it all due to unrequited love or love lost. 22% said they themselves created the problem which led to their decision.
  • Meyer and colleagues also propose a national prevention plan, to foster a sense of community and social support.

    Suicide is a very interesting and big subject in studies of human social activities. From the point of view of evolution, it is a very inefficient act as one kills oneself. This action should be banned from our genes. Gender pressure, as stated in the reading, is probably a factor of suicide. Since the society expect too much on male and some of them are not able to fulfill the expectation, they choose to suicide. It also reminds me of a movie I watched when I was little and left a big impression, called The Happening. In that movie, the plants would release a certain hormone and lead people to suicide one by one. So is it possible that hormone can be a factor of making the decision to suicide? --Sissi (4/6/2017)

  • Although South Africa’s 30-plus species of smaller carnivores play important roles in their ecosystems by keeping populations of prey species in check, which in turn affects plant communities, managers give little, if any, thought to their protection.
  • scientists lack evidence about whether these predictions play out in the real world, especially in small reserves of the sort found in South Africa.
  • While the presence of lions slightly increases the number of small carnivore species living in an area, it decreases their overall range.
  • ...7 more annotations...
  • If lions are present, they have usually been reintroduced.
  • After reintroduction, managers tend to invest significant money and effort into maintaining lion populations, i
  • They found that overall species counts were slightly higher in reserves with lions, but that, on average, lions reduced the amount of land that small carnivores are found on by roughly 30 percent.
  • “The question is, is this the natural role and a good thing for conservation, or is it a negative thing because we’re doing this in a very artificial way?”
  • More study will be required, but if smaller predators are being killed by lions or confined to certain locations where the big cats do not tread, that could lead to population declines of these species and create imbalances for other animals and plants.
  • “However, we need to take heed of the findings of this paper and direct research to ensure we have sufficient information to adapt management to a more holistic approach for the benefit of the whole ecosystem”
  • “There’s more research needed before we can say how much management and conservation priorities are aligned.”

Dengue Mosquitoes Can Be Tamed by a Common Microbe - The Atlantic - 0 views

mosquito infection suppression Science research

shared by Javier E on 14 Jun 21 - No Cached
  • Dengue fever is caused by a virus that infects an estimated 390 million people every year, and kills about 25,000; the World Health Organization has described it as one of the top 10 threats to global health.
  • It spreads through the bites of mosquitoes, particularly the species Aedes aegypti. Utarini and her colleagues have spent the past decade turning these insects from highways of dengue into cul-de-sacs. They’ve loaded the mosquitoes with a bacterium called Wolbachia, which prevents them from being infected by dengue viruses. Wolbachia spreads very quickly: If a small number of carrier mosquitoes are released into a neighborhood, almost all of the local insects should be dengue-free within a few months
  • Aedes aegypti was once a forest insect confined to sub-Saharan Africa, where it drank blood from a wide variety of animals. But at some point, one lineage evolved into an urban creature that prefers towns over forests, and humans over other animals.
  • ...10 more annotations...
  • The World Mosquito Program (WMP), a nonprofit that pioneered this technique, had run small pilot studies in Australia that suggested it could work. Utarini, who co-leads WMP Yogyakarta, has now shown conclusively that it does.
  • Carried around the world aboard slave ships, Aedes aegypti has thrived. It is now arguably the most effective human-hunter on the planet, its senses acutely attuned to the carbon dioxide in our breath, the warmth of our bodies, and the odors of our skin.
  • Wolbachia was first discovered in 1924, in a different species of mosquito. At first, it seemed so unremarkable that scientists ignored it for decades. But starting in the 1980s, they realized that it has an extraordinary knack for spreading. It passes down mainly from insect mothers to their children, and it uses many tricks to ensure that infected individuals are better at reproducing than uninfected ones. To date, it exists in at least 40 percent of all insect species, making it one of the most successful microbes on the planet.
  • The team divided a large portion of the city into 24 zones and released Wolbachia-infected mosquitoes in half of them. Almost 10,000 volunteers helped distribute egg-filled containers to local backyards. Within a year, about 95 percent of the Aedes mosquitoes in the 12 release zones harbored Wolbachia.
  • The team found that just 2.3 percent of feverish people who lived in the Wolbachia release zones had dengue, compared with 9.4 percent in the control areas. Wolbachia also seemed to work against all four dengue serotypes, and reduced the number of dengue hospitalizations by 86 percent.
  • Even then, these already remarkable numbers are likely to be underestimates. The mosquitoes moved around, carrying Wolbachia into the 12 control zones where no mosquitoes were released. And people also move: They might live in a Wolbachia release zone but be bitten and infected with dengue elsewhere. Both of these factors would have worked against the trial, weakening its results
  • The Wolbachia method does have a few limitations. The bacterium takes months to establish itself, so it can’t be “deployed to contain an outbreak today,” Vazquez-Prokopec told me. As the Yogyakarta trial showed, it works only when Wolbachia reaches a prevalence of at least 80 percent, which requires a lot of work and strong community support
  • The method has other benefits too. It is self-amplifying and self-perpetuating: If enough Wolbachia-infected mosquitoes are released initially, the bacterium should naturally come to dominate the local population, and stay that way. Unlike insecticides, Wolbachia isn’t toxic, it doesn’t kill beneficial insects (or even mosquitoes), and it doesn’t need to be reapplied, which makes it very cost-effective.
  • An analysis by Brady’s team showed that it actually saves money by preventing infections
  • Wolbachia also seems to work against the other diseases that Aedes aegypti carries, including Zika and yellow fever. It could transform this mosquito from one of the most dangerous species to humans into just another biting nuisance.

  • Social platforms let us stay in touch with friends and forge new relationships like never before, but those increases in communication and social connection may come at a cost. In a new paper published in the Journal of Experimental Social Psychology, researchers showed that those who documented and shared their experiences on social media formed less precise memories of those events.
  • n a series of three studies led by Diana Tamir of Princeton University, researchers explored how taking photos and videos for social media affects people’s enjoyment, engagement and memory of those experiences.
  • Tamir and her team found that sharing experiences on social media did not seem to affect how much people felt that they had enjoyed the experience or were engaged. However, those who wrote down, recorded or shared their experiences performed about 10% worse on memory tests across all experiments.
  • ...2 more annotations...
  • This availability of external information causes us to neglect information itself, but instead remember where to find it. For example, one study found that if people playing a trivia game believe that a computer is storing each trivia question for them to study later, they do not form a memory of the information they want. Instead, they form a memory of how to retrieve that information on the computer.
  • With the rise of shared content, the exciting activities that you could be doing at any given moment are more apparent than ever, which can lead to a feeling of apprehension that others are having rewarding experiences without you. FOMO, not surprisingly, is associated with being less satisfied with your life, in a worse mood and emotionally unfulfilled.

  • hat is the point of arguing with someone who disagrees with you? Presumably, you would like them to change their mind. But that’s easier said than done

  • The way that people tend to argue today, particularly online, makes things worse.
  • You wouldn’t blame anyone involved for feeling as if they’re under fire, and no one is likely to change their mind when they’re being attacked.
  • odds are that neither camp is having any effect on the other; on the contrary, the attacks make opponents dig in deeper.
  • If you want a chance at changing minds, you need a new strategy: Stop using your values as a weapon, and start offering them as a gift.
  • hilosophers and social scientists have long pondered the question of why people hold different beliefs and values
  • One of the most compelling explanations comes from Moral Foundations Theory, which has been popularized by Jonathan Haidt, a social psychologist at NYU. This theory proposes that humans share a common set of “intuitive ethics,” on top of which we build different narratives and institutions—and therefore beliefs—that vary by culture, community, and even person.
  • Extensive survey-based research has revealed that almost everyone shares at least two common values: Harming others without cause is bad, and fairness is good. Other moral values are less widely shared
  • political conservatives tend to value loyalty to a group, respect for authority, and purity—typically in a bodily sense, in terms of sexuality—more than liberals do.
  • Sometimes conflict arises because one group holds a moral foundation that the other simply doesn’t feel strongly about
  • even when two groups agree on a moral foundation, they can radically disagree on how it should be expressed
  • When people fail to live up to your moral values (or your expression of them), it is easy to conclude that they are immoral people.
  • Further, if you are deeply attached to your values, this difference can feel like a threat to your identity, leading you to lash out, which won’t convince anyone who disagrees with you.
  • research shows that if you insult someone in a disagreement, the odds are that they will harden their position against yours, a phenomenon called the boomerang effect.
  • so it is with our values. If we want any chance at persuasion, we must offer them happily. A weapon is an ugly thing, designed to frighten and coerce
  • effective missionaries present their beliefs as a gift. And sharing a gift is a joyful act, even if not everyone wants it.
  • he solution to this problem requires a change in the way we see and present our own values
  • A gift is something we believe to be good for the recipient, who, we hope, may accept it voluntarily, and do so with gratitude. That requires that we present it with love, not insults and hatred.
  • 1. Don’t “other” others.
  • Go out of your way to welcome those who disagree with you as valued voices, worthy of respect and attention. There is no “them,” only “us.”
  • 2. Don’t take rejection personally.
  • just as you are not your car or your house, you are not your beliefs. Unless someone says, “I hate you because of your views,” a repudiation is personal only if you make it so
  • 3. Listen more.
  • when it comes to changing someone’s mind, listening is more powerful than talking. They conducted experiments that compared polarizing arguments with a nonjudgmental exchange of views accompanied by deep listening. The former had no effect on viewpoints, whereas the latter reliably lowered exclusionary opinions.
  • when possible, listening and asking sensitive questions almost always has a more beneficial effect than talking.
  • howing others that you can be generous with them regardless of their values can help weaken their belief attachment, and thus make them more likely to consider your point of view
  • for your values to truly be a gift, you must weaken your own belief attachment first
  • we should all promise to ourselves, “I will cultivate openness, non-discrimination, and non-attachment to views in order to transform violence, fanaticism, and dogmatism in myself and in the world.”
  • if I truly have the good of the world at heart, then I must not fall prey to the conceit of perfect knowledge, and must be willing to entertain new and better ways to serve my ultimate goal: creating a happier world

  • In people it is called episodic memory, and it involves a sense of self. In animals, it’s called episodic-like memory, because it’s difficult to try to plumb something as elusive as self without the aid of language.
  • Dr. Fugazza and colleagues reported online in Current Biology that this showed that the dogs remembered an event they hadn’t been concentrating on, the trainer’s action. She said one aspect strengthened that conclusion: The dogs tended to lie down immediately when they got back to the mat, suggesting that their heads were in “lie down” mode, not “do it” mode.

    I found this experiment very interesting because it shows some aspect of how animals memory works. The result can be used to see how memory work without language. I think language and memory have an intertwined relationship because sometimes I can feel that the information stored in my brain is in language rather than abstract form such as knowledge. For example, my memory of chemistry knowledge is stored in English, so when I am reading a chemistry related book in Chinese, I would usually get lost because there aren't any vocals on Chemistry in Chinese in my memory. It would be a very interesting question to consider that how our memory will construct if we don't have a language. There is a kind of mental disease called "aphasia", meaning the loss of ability to understand language. How do they remember things when they lose the ability to assign meanings and communicate? --Sissi (11/24/2016)

  • But older females who have more offspring, and thus share more of the group’s genes, are more likely to cooperate by sharing food and knowledge.

    From the TOK class, we learned that the paradigm for biology is Darwin's theory of evolution.

The debate over whether the grandmother hypothesis sounds is still going through vigorous discussion within the scientist community. --Sissi (1/13/2017)

Kids who had five or six items on their list of extracurriculars—the “brag”—were already in trouble, because that wasn’t nearly enough.
  • With so many accomplished applicants to choose from, we were looking for kids with something special, “PQs”—personal qualities—that were often revealed by the letters or essays.

  • On the other hand, the numbers and the résumé were clearly indispensable. I’d been told that successful applicants could either be “well-rounded” or “pointy”—outstanding in one particular way—but if they were pointy, they had to be really pointy: a musician whose audition tape had impressed the music department, a scientist who had won a national award.

  • When I speak of elite education, I mean prestigious institutions like Harvard or Stanford or Williams as well as the larger universe of second-tier selective schools, but I also mean everything that leads up to and away from them—the private and affluent public high schools; the ever-growing industry of tutors and consultants and test-prep courses; the admissions process itself, squatting like a dragon at the entrance to adulthood; the brand-name graduate schools and employment opportunities that come after the B.A.; and the parents and communities, largely upper-middle class, who push their children into the maw of this machine.
  • Our system of elite education manufactures young people who are smart and talented and driven, yes, but also anxious, timid, and lost, with little intellectual curiosity and a stunted sense of purpose: trapped in a bubble of privilege, heading meekly in the same direction, great at what they’re doing but with no idea why they’re doing it.
  • “Super People,” the writer James Atlas has called them—the stereotypical ultra-high-achieving elite college students of today. A double major, a sport, a musical instrument, a couple of foreign languages, service work in distant corners of the globe, a few hobbies thrown in for good measure: They have mastered them all, and with a serene self-assurance
  • Like so many kids today, I went off to college like a sleepwalker. You chose the most prestigious place that let you in; up ahead were vaguely understood objectives: status, wealth—“success.” What it meant to actually get an education and why you might want one—all this was off the table.
  • It was only after 24 years in the Ivy League—college and a Ph.D. at Columbia, ten years on the faculty at Yale—that I started to think about what this system does to kids and how they can escape from it, what it does to our society and how we can dismantle it.
  • I taught many wonderful young people during my years in the Ivy League—bright, thoughtful, creative kids whom it was a pleasure to talk with and learn from. But most of them seemed content to color within the lines that their education had marked out for them. Very few were passionate about ideas. Very few saw college as part of a larger project of intellectual discovery and development. Everyone dressed as if they were ready to be interviewed at a moment’s notice.
  • Look beneath the façade of seamless well-adjustment, and what you often find are toxic levels of fear, anxiety, and depression, of emptiness and aimlessness and isolation. A large-scale survey of college freshmen recently found that self-reports of emotional well-being have fallen to their lowest level in the study’s 25-year history.
  • So extreme are the admission standards now that kids who manage to get into elite colleges have, by definition, never experienced anything but success. The prospect of not being successful terrifies them, disorients them. The cost of falling short, even temporarily, becomes not merely practical, but existential. The result is a violent aversion to risk.
  • There are exceptions, kids who insist, against all odds, on trying to get a real education. But their experience tends to make them feel like freaks. One student told me that a friend of hers had left Yale because she found the school “stifling to the parts of yourself that you’d call a soul.”
  • What no one seems to ask is what the “return” is supposed to be. Is it just about earning more money? Is the only purpose of an education to enable you to get a job? What, in short, is college for?
  • The first thing that college is for is to teach you to think.
  • College is an opportunity to stand outside the world for a few years, between the orthodoxy of your family and the exigencies of career, and contemplate things from a distance.
  • it is only through the act of establishing communication between the mind and the heart, the mind and experience, that you become an individual, a unique being—a soul. The job of college is to assist you to begin to do that. Books, ideas, works of art and thought, the pressure of the minds around you that are looking for their own answers in their own ways.
  • College is not the only chance to learn to think, but it is the best. One thing is certain: If you haven’t started by the time you finish your B.A., there’s little likelihood you’ll do it later. That is why an undergraduate experience devoted exclusively to career preparation is four years largely wasted.
  • Elite schools like to boast that they teach their students how to think, but all they mean is that they train them in the analytic and rhetorical skills that are necessary for success in business and the professions.
  • Everything is technocratic—the development of expertise—and everything is ultimately justified in technocratic terms.
  • Religious colleges—even obscure, regional schools that no one has ever heard of on the coasts—often do a much better job in that respect.
  • At least the classes at elite schools are academically rigorous, demanding on their own terms, no? Not necessarily. In the sciences, usually; in other disciplines, not so much
  • professors and students have largely entered into what one observer called a “nonaggression pact.”

I don’t think it occurs to the people in charge of elite colleges that the concept of leadership ought to have a higher meaning, or, really, any meaning.
  • The irony is that elite students are told that they can be whatever they want, but most of them end up choosing to be one of a few very similar things
  • As of 2010, about a third of graduates went into financing or consulting at a number of top schools, including Harvard, Princeton, and Cornell.

Kids who have ample mental horsepower, an incredible work ethic and no idea what to do next.”
  • t almost feels ridiculous to have to insist that colleges like Harvard are bastions of privilege, where the rich send their children to learn to walk, talk, and think like the rich. Don’t we already know this? They aren’t called elite colleges for nothing. But apparently we like pretending otherwise. We live in a meritocracy, after all.
  • Visit any elite campus across our great nation, and you can thrill to the heart-warming spectacle of the children of white businesspeople and professionals studying and playing alongside the children of black, Asian, and Latino businesspeople and professionals

  • The college admissions game is not primarily about the lower and middle classes seeking to rise, or even about the upper-middle class attempting to maintain its position. It is about determining the exact hierarchy of status within the upper-middle class itself.
  • This system is exacerbating inequality, retarding social mobility, perpetuating privilege, and creating an elite that is isolated from the society that it’s supposed to lead. The numbers are undeniable. In 1985, 46 percent of incoming freshmen at the 250 most selective colleges came from the top quarter of the income distribution. By 2000, it was 55 percent
  • The major reason for the trend is clear. Not increasing tuition, though that is a factor, but the ever-growing cost of manufacturing children who are fit to compete in the college admissions game
  • Wealthy families start buying their children’s way into elite colleges almost from the moment they are born: music lessons, sports equipment, foreign travel (“enrichment” programs, to use the all-too-perfect term)—most important, of course, private-school tuition or the costs of living in a place with top-tier public schools.

  • Elite private colleges will never allow their students’ economic profile to mirror that of society as a whole. They can’t afford to—they need a critical mass of full payers and they need to tend to their donor base—and it’s not even clear that they’d want to.
  • Elite colleges are not just powerless to reverse the movement toward a more unequal society; their policies actively promote it.
  • The SAT is supposed to measure aptitude, but what it actually measures is parental income, which it tracks quite closely
  • U.S. News and World Report supplies the percentage of freshmen at each college who finished in the highest 10 percent of their high school class. Among the top 20 universities, the number is usually above 90 percent. I’d be wary of attending schools like that. Students determine the level of classroom discussion; they shape your values and expectations, for good and ill. It’s partly because of the students that I’d warn kids away from the Ivies and their ilk. Kids at less prestigious schools are apt to be more interesting, more curious, more open, and far less entitled and competitive.
  • The best option of all may be the second-tier—not second-rate—colleges, like Reed, Kenyon, Wesleyan, Sewanee, Mount Holyoke, and others. Instead of trying to compete with Harvard and Yale, these schools have retained their allegiance to real educational values.
  • Not being an entitled little shit is an admirable goal. But in the end, the deeper issue is the situation that makes it so hard to be anything else. The time has come, not simply to reform that system top to bottom, but to plot our exit to another kind of society altogether.
  • The education system has to act to mitigate the class system, not reproduce it. Affirmative action should be based on class instead of race, a change that many have been advocating for years. Preferences for legacies and athletes ought to be discarded. SAT scores should be weighted to account for socioeconomic factors. Colleges should put an end to résumé-stuffing by imposing a limit on the number of extracurriculars that kids can list on their applications. They ought to place more value on the kind of service jobs that lower-income students often take in high school and that high achievers almost never do. They should refuse to be impressed by any opportunity that was enabled by parental wealth
  • More broadly, they need to rethink their conception of merit. If schools are going to train a better class of leaders than the ones we have today, they’re going to have to ask themselves what kinds of qualities they need to promote. Selecting students by GPA or the number of extracurriculars more often benefits the faithful drudge than the original mind.
  • reforming the admissions process. That might address the problem of mediocrity, but it won’t address the greater one of inequality

Shouting into the apocalypse: The decade in climate change (opinion) - CNN - 0 views

  • What's that worn-out phrase? Shouting into the wind? Well, after a decade of rising pollution, failed politics and worsening disasters, it seems the many, many of us who care about the climate crisis increasingly are shouting into the hurricane, if not the apocalypse.
  • On the cusp of 2020, the state of the planet is far more dire than in 2010. Preserving a safe and healthy ecological system is no longer a realistic possibility. Now, we're looking at less bad options, ceding the fact that the virtual end of coral reefs, the drowning of some island nations, the worsening of already-devastating storms and the displacement of millions -- they seem close to inevitable. The climate crisis is already costly, deadly and deeply unjust, putting the most vulnerable people in the world, often who've done the least to cause this, at terrible risk.
  • There are two numbers you need to understand to put this moment in perspective.The first is 1.5. The Paris Agreement -- the international treaty on climate change, which admittedly is in trouble, but also is the best thing we've got -- sets the goal of limiting warming to 1.5 or, at most, below 2 degrees Celsius of warming.

  • Worldwide fossil fuel emissions are expected to be up 0.6% in 2019 over 2018, according to projections from the Global Carbon Project. In the past decade, humans have put more than 350 metric gigatons of carbon dioxide into the atmosphere from burning fossil fuels and other industrial processes, according to calculations provided by the World Resources Institute.
  • Meanwhile, scientists are becoming even more concerned about tipping points in the climate system that could lead to rapid rise in sea levels, the deterioration of the Amazon and so on. One particularly frightening commentary last month in the journal Nature, by several notable climate scientists, says the odds we can avoid tipping points in the climate system "could already have shrunk towards zero." In non-science-speak: We're there now.
  • This was the decade when some people finally started to see the climate crisis as personal. Climate attribution science, which looks for human fingerprints on extreme weather events, made its way into the popular imagination. We're starting to realize there are no truly "natural" disasters anymore. We've warmed the climate, and we're already making storms riskier.
  • The news media is picking that up, using terms such as "climate emergency" and "climate crisis" instead of the blander "climate change." Increasingly, lots of people are making these critical connections, which should motivate the political, social and economic revolution necessary to fix things.
  • Only 52% of American adults say they are "very" or "extremely" sure global warming is happening, according to a report from the Yale Program on Climate Change Communication and the George Mason University Center for Climate Change Communication, which is based on a 1,303 person survey conducted in November 2019. Yale's been asking that question for a while now. Go back a decade, to 2009, and the rate is about the same: 51%.
  • The bright spot -- and it truly is a bright one -- is that young people are waking up. They are shouting, loudly and with purpose. Witness Greta Thunberg, the dynamic teenager who started a one-girl protest outside the Swedish Parliament last year, demanding that adults take seriously this emergency, which threatens young people and future generations disproportionately.

  • Brain scientists can watch neurons fire and communicate. They can map how brain regions light up during sensation, decision-making, and speech. What they can't explain is how all this activity gives rise to consciousness.
  • But understanding consciousness has become increasingly important for researchers seeking to communicate with locked-in patients, determine whether artificial intelligence systems can become conscious, or explore whether animals experience consciousness the way humans do.
  • The GWT says the brain's prefrontal cortex, which controls higher order cognitive processes like decision-making, acts as a central computer that collects and prioritizes information from sensory input. It then broadcasts the information to other parts of the brain that carry out tasks.

  • The project has drawn criticism, mostly because it includes the IIT. Anil Seth, a neuroscientist at the University of Sussex in Brighton, U.K., says the theory is too philosophical—attempting to explain why consciousness exists, rather than how the brain determines whether a stimulus is worthy of conscious attention—to be directly testable.

  • “We’re used to thinking that information about an object — say that a glass is half full — is somehow contained within the object.” Instead, he says, entanglement means objects “only exist in relation to other objects, and moreover these relationships are encoded in a wave function that stands outside the tangible physical universe.”
  • Einstein, though one of the founders of quantum theory, rejected it, saying famously, God did not play dice with the universe.In a 1935 paper written with Boris Podolsky and Nathan Rosen, he tried to demolish quantum mechanics as an incomplete theory by pointing out that by quantum rules, measuring a particle in one place could instantly affect measurements of the other particle, even if it was millions of miles away.
  • Dr. Clauser, who has a knack for electronics and experimentation and misgivings about quantum theory, was the first to perform Bell’s proposed experiment. He happened upon Dr. Bell’s paper while a graduate student at Columbia University and recognized it as something he could do.

  • In 1972, using duct tape and spare parts in the basement on the campus of the University of California, Berkeley, Dr. Clauser and a graduate student, Stuart Freedman, who died in 2012, endeavored to perform Bell’s experiment to measure quantum entanglement. In a series of experiments, he fired thousands of light particles, or photons, in opposite directions to measure a property known as polarization, which could have only two values — up or down. The result for each detector was always a series of seemingly random ups and downs. But when the two detectors’ results were compared, the ups and downs matched in ways that neither “classical physics” nor Einstein’s laws could explain. Something weird was afoot in the universe. Entanglement seemed to be real.
  • in 2002, Dr. Clauser admitted that he himself had expected quantum mechanics to be wrong and Einstein to be right. “Obviously, we got the ‘wrong’ result. I had no choice but to report what we saw, you know, ‘Here’s the result.’ But it contradicts what I believed in my gut has to be true.” He added, “I hoped we would overthrow quantum mechanics. Everyone else thought, ‘John, you’re totally nuts.’”
  • the correlations only showed up after the measurements of the individual particles, when the physicists compared their results after the fact. Entanglement seemed real, but it could not be used to communicate information faster than the speed of light.
  • In 1982, Dr. Aspect and his team at the University of Paris tried to outfox Dr. Clauser’s loophole by switching the direction along which the photons’ polarizations were measured every 10 nanoseconds, while the photons were already in the air and too fast for them to communicate with each other. He too, was expecting Einstein to be right.
  • Quantum predictions held true, but there were still more possible loopholes in the Bell experiment that Dr. Clauser had identified
  • For example, the polarization directions in Dr. Aspect’s experiment had been changed in a regular and thus theoretically predictable fashion that could be sensed by the photons or detectors.
  • Anton Zeilinger
  • added even more randomness to the Bell experiment, using random number generators to change the direction of the polarization measurements while the entangled particles were in flight.
  • Once again, quantum mechanics beat Einstein by an overwhelming margin, closing the “locality” loophole.
  • as scientists have done more experiments with entangled particles, entanglement is accepted as one of main features of quantum mechanics and is being put to work in cryptology, quantum computing and an upcoming “quantum internet
  • One of its first successes in cryptology is messages sent using entangled pairs, which can send cryptographic keys in a secure manner — any eavesdropping will destroy the entanglement, alerting the receiver that something is wrong.

  • In his interview with A.I.P., Dr. Clauser said, “I confess even to this day that I still don’t understand quantum mechanics, and I’m not even sure I really know how to use it all that well. And a lot of this has to do with the fact that I still don’t understand it.”

  • Social scientists have identified at least three major forces that collectively bind together successful democracies: social capital (extensive social networks with high levels of trust), strong institutions, and shared stories.
  • Social media has weakened all three.
  • gradually, social-media users became more comfortable sharing intimate details of their lives with strangers and corporations. As I wrote in a 2019 Atlantic article with Tobias Rose-Stockwell, they became more adept at putting on performances and managing their personal brand—activities that might impress others but that do not deepen friendships in the way that a private phone conversation will.

  • the stage was set for the major transformation, which began in 2009: the intensification of viral dynamics.
  • Before 2009, Facebook had given users a simple timeline––a never-ending stream of content generated by their friends and connections, with the newest posts at the top and the oldest ones at the bottom
  • That began to change in 2009, when Facebook offered users a way to publicly “like” posts with the click of a button. That same year, Twitter introduced something even more powerful: the “Retweet” button, which allowed users to publicly endorse a post while also sharing it with all of their followers.
  • “Like” and “Share” buttons quickly became standard features of most other platforms.
  • Facebook developed algorithms to bring each user the content most likely to generate a “like” or some other interaction, eventually including the “share” as well.
  • Later research showed that posts that trigger emotions––especially anger at out-groups––are the most likely to be shared.
  • By 2013, social media had become a new game, with dynamics unlike those in 2008. If you were skillful or lucky, you might create a post that would “go viral” and make you “internet famous”
  • If you blundered, you could find yourself buried in hateful comments. Your posts rode to fame or ignominy based on the clicks of thousands of strangers, and you in turn contributed thousands of clicks to the game.
  • This new game encouraged dishonesty and mob dynamics: Users were guided not just by their true preferences but by their past experiences of reward and punishment,
  • As a social psychologist who studies emotion, morality, and politics, I saw this happening too. The newly tweaked platforms were almost perfectly designed to bring out our most moralistic and least reflective selves. The volume of outrage was shocking.
  • It was just this kind of twitchy and explosive spread of anger that James Madison had tried to protect us from as he was drafting the U.S. Constitution.
  • The Framers of the Constitution were excellent social psychologists. They knew that democracy had an Achilles’ heel because it depended on the collective judgment of the people, and democratic communities are subject to “the turbulency and weakness of unruly passions.”
  • The key to designing a sustainable republic, therefore, was to build in mechanisms to slow things down, cool passions, require compromise, and give leaders some insulation from the mania of the moment while still holding them accountable to the people periodically, on Election Day.
  • The tech companies that enhanced virality from 2009 to 2012 brought us deep into Madison’s nightmare.
  • a less quoted yet equally important insight, about democracy’s vulnerability to triviality.
  • Madison notes that people are so prone to factionalism that “where no substantial occasion presents itself, the most frivolous and fanciful distinctions have been sufficient to kindle their unfriendly passions and excite their most violent conflicts.”
  • Social media has both magnified and weaponized the frivolous.
  • It’s not just the waste of time and scarce attention that matters; it’s the continual chipping-away of trust.
  • a democracy depends on widely internalized acceptance of the legitimacy of rules, norms, and institutions.
  • when citizens lose trust in elected leaders, health authorities, the courts, the police, universities, and the integrity of elections, then every decision becomes contested; every election becomes a life-and-death struggle to save the country from the other side
  • The most recent Edelman Trust Barometer (an international measure of citizens’ trust in government, business, media, and nongovernmental organizations) showed stable and competent autocracies (China and the United Arab Emirates) at the top of the list, while contentious democracies such as the United States, the United Kingdom, Spain, and South Korea scored near the bottom (albeit above Russia).
  • The literature is complex—some studies show benefits, particularly in less developed democracies—but the review found that, on balance, social media amplifies political polarization; foments populism, especially right-wing populism; and is associated with the spread of misinformation.
  • When people lose trust in institutions, they lose trust in the stories told by those institutions. That’s particularly true of the institutions entrusted with the education of children.
  • Facebook and Twitter make it possible for parents to become outraged every day over a new snippet from their children’s history lessons––and math lessons and literature selections, and any new pedagogical shifts anywhere in the country
  • The motives of teachers and administrators come into question, and overreaching laws or curricular reforms sometimes follow, dumbing down education and reducing trust in it further.

Gurri’s analysis focused on the authority-subverting effects of information’s exponential growth, beginning with the internet in the 1990s. Writing nearly a decade ago, Gurri could already see the power of social media as a universal solvent, breaking down bonds and weakening institutions everywhere it reached.

  • Facebook, Twitter, YouTube, and a few other large platforms unwittingly dissolved the mortar of trust, belief in institutions, and shared stories that had held a large and diverse secular democracy together.
  • I think we can date the fall of the tower to the years between 2011 (Gurri’s focal year of “nihilistic” protests) and 2015, a year marked by the “great awokening” on the left and the ascendancy of Donald Trump on the right.
  • Twitter can overpower all the newspapers in the country, and stories cannot be shared (or at least trusted) across more than a few adjacent fragments—so truth cannot achieve widespread adherence.
  • fter Babel, nothing really means anything anymore––at least not in a way that is durable and on which people widely agree.
  • Politics After Babel
  • “Politics is the art of the possible,” the German statesman Otto von Bismarck said in 1867. In a post-Babel democracy, not much may be possible.
  • The ideological distance between the two parties began increasing faster in the 1990s. Fox News and the 1994 “Republican Revolution” converted the GOP into a more combative party.
  • So cross-party relationships were already strained before 2009. But the enhanced virality of social media thereafter made it more hazardous to be seen fraternizing with the enemy or even failing to attack the enemy with sufficient vigor.
  • What changed in the 2010s? Let’s revisit that Twitter engineer’s metaphor of handing a loaded gun to a 4-year-old. A mean tweet doesn’t kill anyone; it is an attempt to shame or punish someone publicly while broadcasting one’s own virtue, brilliance, or tribal loyalties. It’s more a dart than a bullet

  • the warped “accountability” of social media has also brought injustice—and political dysfunction—in three ways.
  • First, the dart guns of social media give more power to trolls and provocateurs while silencing good citizens.
  • a small subset of people on social-media platforms are highly concerned with gaining status and are willing to use aggression to do so.
  • Across eight studies, Bor and Petersen found that being online did not make most people more aggressive or hostile; rather, it allowed a small number of aggressive people to attack a much larger set of victims. Even a small number of jerks were able to dominate discussion forums,
  • Additional research finds that women and Black people are harassed disproportionately, so the digital public square is less welcoming to their voices.
  • Second, the dart guns of social media give more power and voice to the political extremes while reducing the power and voice of the moderate majority.
  • The “Hidden Tribes” study, by the pro-democracy group More in Common, surveyed 8,000 Americans in 2017 and 2018 and identified seven groups that shared beliefs and behaviors.
  • Social media has given voice to some people who had little previously, and it has made it easier to hold powerful people accountable for their misdeeds
  • The group furthest to the left, the “progressive activists,” comprised 8 percent of the population. The progressive activists were by far the most prolific group on social media: 70 percent had shared political content over the previous year. The devoted conservatives followed, at 56 percent.
  • These two extreme groups are similar in surprising ways. They are the whitest and richest of the seven groups, which suggests that America is being torn apart by a battle between two subsets of the elite who are not representative of the broader society.

  • political extremists don’t just shoot darts at their enemies; they spend a lot of their ammunition targeting dissenters or nuanced thinkers on their own team.
  • Finally, by giving everyone a dart gun, social media deputizes everyone to administer justice with no due process. Platforms like Twitter devolve into the Wild West, with no accountability for vigilantes.
  • Enhanced-virality platforms thereby facilitate massive collective punishment for small or imagined offenses, with real-world consequences, including innocent people losing their jobs and being shamed into suicide
  • we don’t get justice and inclusion; we get a society that ignores context, proportionality, mercy, and truth.
  • Since the tower fell, debates of all kinds have grown more and more confused. The most pervasive obstacle to good thinking is confirmation bias, which refers to the human tendency to search only for evidence that confirms our preferred beliefs
  • search engines were supercharging confirmation bias, making it far easier for people to find evidence for absurd beliefs and conspiracy theorie
  • The most reliable cure for confirmation bias is interaction with people who don’t share your beliefs. They confront you with counterevidence and counterargument.
  • In his book The Constitution of Knowledge, Jonathan Rauch describes the historical breakthrough in which Western societies developed an “epistemic operating system”—that is, a set of institutions for generating knowledge from the interactions of biased and cognitively flawed individuals
  • English law developed the adversarial system so that biased advocates could present both sides of a case to an impartial jury.
  • Newspapers full of lies evolved into professional journalistic enterprises, with norms that required seeking out multiple sides of a story, followed by editorial review, followed by fact-checking.
  • Universities evolved from cloistered medieval institutions into research powerhouses, creating a structure in which scholars put forth evidence-backed claims with the knowledge that other scholars around the world would be motivated to gain prestige by finding contrary evidence.
  • Part of America’s greatness in the 20th century came from having developed the most capable, vibrant, and productive network of knowledge-producing institutions in all of human history
  • But this arrangement, Rauch notes, “is not self-maintaining; it relies on an array of sometimes delicate social settings and understandings, and those need to be understood, affirmed, and protected.”

  • The stupefying process plays out differently on the right and the left because their activist wings subscribe to different narratives with different sacred values.
  • The “Hidden Tribes” study tells us that the “devoted conservatives” score highest on beliefs related to authoritarianism. They share a narrative in which America is eternally under threat from enemies outside and subversives within; they see life as a battle between patriots and traitors.

  • The wave of threats delivered to dissenting Republican members of Congress has similarly pushed many of the remaining moderates to quit or go silent, giving us a party ever more divorced from the conservative tradition, constitutional responsibility, and reality.
  • The stupidity on the right is most visible in the many conspiracy theories spreading across right-wing media and now into Congress.
  • The Democrats have also been hit hard by structural stupidity, though in a different way. In the Democratic Party, the struggle between the progressive wing and the more moderate factions is open and ongoing, and often the moderates win.
  • The problem is that the left controls the commanding heights of the culture: universities, news organizations, Hollywood, art museums, advertising, much of Silicon Valley, and the teachers’ unions and teaching colleges that shape K–12 education. And in many of those institutions, dissent has been stifled:
  • Liberals in the late 20th century shared a belief that the sociologist Christian Smith called the “liberal progress” narrative, in which America used to be horrifically unjust and repressive, but, thanks to the struggles of activists and heroes, has made (and continues to make) progress toward realizing the noble promise of its founding.
  • It is also the view of the “traditional liberals” in the “Hidden Tribes” study (11 percent of the population), who have strong humanitarian values, are older than average, and are largely the people leading America’s cultural and intellectual institutions.
  • when the newly viralized social-media platforms gave everyone a dart gun, it was younger progressive activists who did the most shooting, and they aimed a disproportionate number of their darts at these older liberal leaders.
  • Confused and fearful, the leaders rarely challenged the activists or their nonliberal narrative in which life at every institution is an eternal battle among identity groups over a zero-sum pie, and the people on top got there by oppressing the people on the bottom. This new narrative is rigidly egalitarian––focused on equality of outcomes, not of rights or opportunities. It is unconcerned with individual rights.
  • The universal charge against people who disagree with this narrative is not “traitor”; it is “racist,” “transphobe,” “Karen,” or some related scarlet letter marking the perpetrator as one who hates or harms a marginalized group.
  • The punishment that feels right for such crimes is not execution; it is public shaming and social death.
  • anyone on Twitter had already seen dozens of examples teaching the basic lesson: Don’t question your own side’s beliefs, policies, or actions. And when traditional liberals go silent, as so many did in the summer of 2020, the progressive activists’ more radical narrative takes over as the governing narrative of an organization.
  • This is why so many epistemic institutions seemed to “go woke” in rapid succession that year and the next, beginning with a wave of controversies and resignations at The New York Times and other newspapers, and continuing on to social-justice pronouncements by groups of doctors and medical associations
  • The problem is structural. Thanks to enhanced-virality social media, dissent is punished within many of our institutions, which means that bad ideas get elevated into official policy.
  • In a 2018 interview, Steve Bannon, the former adviser to Donald Trump, said that the way to deal with the media is “to flood the zone with shit.” He was describing the “firehose of falsehood” tactic pioneered by Russian disinformation programs to keep Americans confused, disoriented, and angry.
  • artificial intelligence is close to enabling the limitless spread of highly believable disinformation. The AI program GPT-3 is already so good that you can give it a topic and a tone and it will spit out as many essays as you like, typically with perfect grammar and a surprising level of coherence.
  • Renée DiResta, the research manager at the Stanford Internet Observatory, explained that spreading falsehoods—whether through text, images, or deep-fake videos—will quickly become inconceivably easy. (She co-wrote the essay with GPT-3.)
  • American factions won’t be the only ones using AI and social media to generate attack content; our adversaries will too.
  • In the 20th century, America’s shared identity as the country leading the fight to make the world safe for democracy was a strong force that helped keep the culture and the polity together.
  • In the 21st century, America’s tech companies have rewired the world and created products that now appear to be corrosive to democracy, obstacles to shared understanding, and destroyers of the modern tower.
  • What changes are needed?
  • I can suggest three categories of reforms––three goals that must be achieved if democracy is to remain viable in the post-Babel era.
  • We must harden democratic institutions so that they can withstand chronic anger and mistrust, reform social media so that it becomes less socially corrosive, and better prepare the next generation for democratic citizenship in this new age.
  • Harden Democratic Institutions
  • we must reform key institutions so that they can continue to function even if levels of anger, misinformation, and violence increase far above those we have today.
  • Reforms should reduce the outsize influence of angry extremists and make legislators more responsive to the average voter in their district.
  • One example of such a reform is to end closed party primaries, replacing them with a single, nonpartisan, open primary from which the top several candidates advance to a general election that also uses ranked-choice voting
  • A second way to harden democratic institutions is to reduce the power of either political party to game the system in its favor, for example by drawing its preferred electoral districts or selecting the officials who will supervise elections
  • These jobs should all be done in a nonpartisan way.
  • Reform Social Media
  • Social media’s empowerment of the far left, the far right, domestic trolls, and foreign agents is creating a system that looks less like democracy and more like rule by the most aggressive.
  • it is within our power to reduce social media’s ability to dissolve trust and foment structural stupidity. Reforms should limit the platforms’ amplification of the aggressive fringes while giving more voice to what More in Common calls “the exhausted majority.”
  • the main problem with social media is not that some people post fake or toxic stuff; it’s that fake and outrage-inducing content can now attain a level of reach and influence that was not possible before
  • Perhaps the biggest single change that would reduce the toxicity of existing platforms would be user verification as a precondition for gaining the algorithmic amplification that social media offers.
  • One of the first orders of business should be compelling the platforms to share their data and their algorithms with academic researchers.
  • Prepare the Next Generation
  • Childhood has become more tightly circumscribed in recent generations––with less opportunity for free, unstructured play; less unsupervised time outside; more time online. Whatever else the effects of these shifts, they have likely impeded the development of abilities needed for effective self-governance for many young adults
  • Depression makes people less likely to want to engage with new people, ideas, and experiences. Anxiety makes new things seem more threatening. As these conditions have risen and as the lessons on nuanced social behavior learned through free play have been delayed, tolerance for diverse viewpoints and the ability to work out disputes have diminished among many young people
  • Students did not just say that they disagreed with visiting speakers; some said that those lectures would be dangerous, emotionally devastating, a form of violence. Because rates of teen depression and anxiety have continued to rise into the 2020s, we should expect these views to continue in the generations to follow, and indeed to become more severe.
  • The most important change we can make to reduce the damaging effects of social media on children is to delay entry until they have passed through puberty.
  • The age should be raised to at least 16, and companies should be held responsible for enforcing it.
  • et them out to play. Stop starving children of the experiences they most need to become good citizens: free play in mixed-age groups of children with minimal adult supervision
  • while social media has eroded the art of association throughout society, it may be leaving its deepest and most enduring marks on adolescents. A surge in rates of anxiety, depression, and self-harm among American teens began suddenly in the early 2010s. (The same thing happened to Canadian and British teens, at the same time.) The cause is not known, but the timing points to social media as a substantial contributor—the surge began just as the large majority of American teens became daily users of the major platforms.
  • What would it be like to live in Babel in the days after its destruction? We know. It is a time of confusion and loss. But it is also a time to reflect, listen, and build.
  • In recent years, Americans have started hundreds of groups and organizations dedicated to building trust and friendship across the political divide, including BridgeUSA, Braver Angels (on whose board I serve), and many others listed at BridgeAlliance.us. We cannot expect Congress and the tech companies to save us. We must change ourselves and our communities.
  • when we look away from our dysfunctional federal government, disconnect from social media, and talk with our neighbors directly, things seem more hopeful. Most Americans in the More in Common report are members of the “exhausted majority,” which is tired of the fighting and is willing to listen to the other side and compromise. Most Americans now see that social media is having a negative impact on the country, and are becoming more aware of its damaging effects on children.

  • For much of 2020, doctors and public-health officials thought the virus was transmitted through droplets emitted from one person’s mouth and touched or inhaled by another person nearby. We were advised to stay at least 6 feet away from each other to avoid the droplets
  • A small cadre of aerosol scientists had a different theory. They suspected that Covid-19 was transmitted not so much by droplets but by smaller infectious aerosol particles that could travel on air currents way farther than 6 feet and linger in the air for hours. Some of the aerosol particles, they believed, were small enough to penetrate the cloth masks widely used at the time.
  • The group had a hard time getting public-health officials to embrace their theory. For one thing, many of them were engineers, not doctors.
  • ...37 more annotations...
  • “My first and biggest wish is that we had known early that Covid-19 was airborne,”
  • , “Once you’ve realized that, it informs an entirely different strategy for protection.” Masking, ventilation and air cleaning become key, as well as avoiding high-risk encounters with strangers, he says.
  • Instead of washing our produce and wearing hand-sewn cloth masks, we could have made sure to avoid superspreader events and worn more-effective N95 masks or their equivalent. “We could have made more of an effort to develop and distribute N95s to everyone,” says Dr. Volckens. “We could have had an Operation Warp Speed for masks.”
  • We didn’t realize how important clear, straight talk would be to maintaining public trust. If we had, we could have explained the biological nature of a virus and warned that Covid-19 would change in unpredictable ways.  
  • We didn’t know how difficult it would be to get the basic data needed to make good public-health and medical decisions. If we’d had the data, we could have more effectively allocated scarce resources
  • In the face of a pandemic, he says, the public needs an early basic and blunt lesson in virology
  • and mutates, and since we’ve never seen this particular virus before, we will need to take unprecedented actions and we will make mistakes, he says.
  • Since the public wasn’t prepared, “people weren’t able to pivot when the knowledge changed,”
  • By the time the vaccines became available, public trust had been eroded by myriad contradictory messages—about the usefulness of masks, the ways in which the virus could be spread, and whether the virus would have an end date.
  • , the absence of a single, trusted source of clear information meant that many people gave up on trying to stay current or dismissed the different points of advice as partisan and untrustworthy.
  • “The science is really important, but if you don’t get the trust and communication right, it can only take you so far,”
  • people didn’t know whether it was OK to visit elderly relatives or go to a dinner party.
  • Doctors didn’t know what medicines worked. Governors and mayors didn’t have the information they needed to know whether to require masks. School officials lacked the information needed to know whether it was safe to open schools.
  • Had we known that even a mild case of Covid-19 could result in long Covid and other serious chronic health problems, we might have calculated our own personal risk differently and taken more care.
  • just months before the outbreak of the pandemic, the Council of State and Territorial Epidemiologists released a white paper detailing the urgent need to modernize the nation’s public-health system still reliant on manual data collection methods—paper records, phone calls, spreadsheets and faxes.
  • While the U.K. and Israel were collecting and disseminating Covid case data promptly, in the U.S. the CDC couldn’t. It didn’t have a centralized health-data collection system like those countries did, but rather relied on voluntary reporting by underfunded state and local public-health systems and hospitals.
  • doctors and scientists say they had to depend on information from Israel, the U.K. and South Africa to understand the nature of new variants and the effectiveness of treatments and vaccines. They relied heavily on private data collection efforts such as a dashboard at Johns Hopkins University’s Coronavirus Resource Center that tallied cases, deaths and vaccine rates globally.
  • For much of the pandemic, doctors, epidemiologists, and state and local governments had no way to find out in real time how many people were contracting Covid-19, getting hospitalized and dying
  • To solve the data problem, Dr. Ranney says, we need to build a public-health system that can collect and disseminate data and acts like an electrical grid. The power company sees a storm coming and lines up repair crews.
  • If we’d known how damaging lockdowns would be to mental health, physical health and the economy, we could have taken a more strategic approach to closing businesses and keeping people at home.
  • t many doctors say they were crucial at the start of the pandemic to give doctors and hospitals a chance to figure out how to accommodate and treat the avalanche of very sick patients.
  • The measures reduced deaths, according to many studies—but at a steep cost.
  • The lockdowns didn’t have to be so harmful, some scientists say. They could have been more carefully tailored to protect the most vulnerable, such as those in nursing homes and retirement communities, and to minimize widespread disruption.
  • Lockdowns could, during Covid-19 surges, close places such as bars and restaurants where the virus is most likely to spread, while allowing other businesses to stay open with safety precautions like masking and ventilation in place.  
  • The key isn’t to have the lockdowns last a long time, but that they are deployed earlier,
  • If England’s March 23, 2020, lockdown had begun one week earlier, the measure would have nearly halved the estimated 48,600 deaths in the first wave of England’s pandemic
  • If the lockdown had begun a week later, deaths in the same period would have more than doubled
  • It is possible to avoid lockdowns altogether. Taiwan, South Korea and Hong Kong—all countries experienced at handling disease outbreaks such as SARS in 2003 and MERS—avoided lockdowns by widespread masking, tracking the spread of the virus through testing and contact tracing and quarantining infected individuals.
  • With good data, Dr. Ranney says, she could have better managed staffing and taken steps to alleviate the strain on doctors and nurses by arranging child care for them.
  • Early in the pandemic, public-health officials were clear: The people at increased risk for severe Covid-19 illness were older, immunocompromised, had chronic kidney disease, Type 2 diabetes or serious heart conditions
  • t had the unfortunate effect of giving a false sense of security to people who weren’t in those high-risk categories. Once case rates dropped, vaccines became available and fear of the virus wore off, many people let their guard down, ditching masks, spending time in crowded indoor places.
  • it has become clear that even people with mild cases of Covid-19 can develop long-term serious and debilitating diseases. Long Covid, whose symptoms include months of persistent fatigue, shortness of breath, muscle aches and brain fog, hasn’t been the virus’s only nasty surprise
  • In February 2022, a study found that, for at least a year, people who had Covid-19 had a substantially increased risk of heart disease—even people who were younger and had not been hospitalized
  • respiratory conditions.
  • Some scientists now suspect that Covid-19 might be capable of affecting nearly every organ system in the body. It may play a role in the activation of dormant viruses and latent autoimmune conditions people didn’t know they had
  •  A blood test, he says, would tell people if they are at higher risk of long Covid and whether they should have antivirals on hand to take right away should they contract Covid-19.
  • If the risks of long Covid had been known, would people have reacted differently, especially given the confusion over masks and lockdowns and variants? Perhaps. At the least, many people might not have assumed they were out of the woods just because they didn’t have any of the risk factors.

The American Scholar: Hardwired for Talk? - Jessica Love - 0 views

language development theory genetics research psychology

shared by Javier E on 04 Apr 13 - No Cached
  • during the last decade, the pendulum of scientific thought has begun its inevitable swing in the other direction. These days, general cognitive mechanisms, not language-specific ones, are all the rage. We humans are really smart. We’re fantastic at recognizing patterns in our environments—patterns that may have nothing to do with language. Who says that the same abilities that allow us to play the violin aren’t also sufficient for learning subject-verb agreement? Perhaps speech isn’t genetically privileged so much as babies are just really motivated to learn to communicate.
  • If the brain did evolve for language, how did it do so? An idea favored by some scholars is that better communicators may also have been more reproductively successful. Gradually, as the prevalence of these smooth talkers’ offspring increased in the population, the concentration of genes favorable to linguistic communication may have increased as well.
  • two recent articles, one published in 2009 in the Proceedings of the National Academy of the Sciences and a 2012 follow-up in PLOS ONE (freely available), rebut this approach
  • ...4 more annotations...
  • Over the course of many generations, the gene pool thickens with helpful alleles until—voila!—the overwhelming number of these alleles are helpful and learners guesses are so uncannily accurate as to seem instinctual. Makes sense, no? But now consider that languages change. (And in the real world they do—quickly.) If the language’s principles switch often, many of those helpfully biased alleles are suddenly not so helpful at all. For fast-changing languages, the model finds, neutral alleles win out:
  • when the language is programmed to hardly mutate at all, the genes have a chance to adapt to the new language. The two populations become genetically distinct, their alleles heavily biased toward the idiosyncrasies of their local language—precisely what we don’t see in the real world
  • when the language is programmed to change quickly, neutral alleles are again favored.
  • maybe our brains couldn’t have evolved to handle language’s more arbitrary properties, because languages never stay the same and, as far as we know, they never have. What goes unspoken here is that the simulations seem to suggest that truly universal properties—such as language’s hierarchical nature—could have been encoded in our brains.

How Social Isolation Is Killing Us - The New York Times - 0 views

  • About one-third of Americans older than 65 now live alone, and half of those over 85 do. People in poorer health — especially those with mood disorders like anxiety and depression — are more likely to feel lonely. Those without a college education are the least likely to have someone they can talk to about important personal matters.
  • Loneliness can accelerate cognitive decline in older adults, and isolated individuals are twice as likely to die prematurely as those with more robust social interactions. These effects start early: Socially isolated children have significantly poorer health 20 years later, even after controlling for other factors. All told, loneliness is as important a risk factor for early death as obesity and smoking.
  • The loneliness of older adults has different roots — often resulting from family members moving away and close friends passing away. As one senior put it, “Your world dies before you do.”

  • “In America, you almost need an excuse for knocking on a neighbor’s door,” Dr. Tang told me. “We want to break down those barriers.”

  • A great paradox of our hyper-connected digital age is that we seem to be drifting apart. Increasingly, however, research confirms our deepest intuition: Human connection lies at the heart of human well-being. It’s up to all of us — doctors, patients, neighborhoods and communities — to maintain bonds where they’re fading, and create ones where they haven’t existed.
  • sissij on 23 Dec 16
     
    We are always finding reasons to do something good for others. However, these barriers are just invented. We don't need reason to be kind and friendly. The digital age gives us access to more people, but it also limits attention and effort to form a friendship. Our brain is limited so there is attention blindness showing that we cannot handle too much information. What we should do is focus our attention on people in our community and actually make effort to form relationships and connections. Usually, people that's most realistic and close to us are not online. --Sissi (12/23/2016)
