The Agency Moment - NYTimes.com - 0 views

  • I’ve been thinking about moments of agency of this sort because often you see people who lack full agency. Sometimes you see lack of agency among the disadvantaged. Their lives can be so blown about by economic disruption, arbitrary bosses and general disorder that they lose faith in the idea that input leads to predictable output.
  • Among the privileged, especially the privileged young, you see people who have been raised to be approval-seeking machines. They act active, busy and sleepless, but inside they often feel passive and not in control. Their lives are directed by other people’s expectations, external criteria and definitions of success that don’t actually fit them.
  • So many people are struggling for agency. They are searching for the solid criteria that will help them make their own judgments. They are hoping to light an inner fire that will fuel relentless action in the same direction.

  • Agency is not automatic. It has to be given birth to, with pushing and effort. It’s not just the confidence and drive to act. It’s having engraved inner criteria to guide action. The agency moment can happen at any age, or never. I guess that’s when adulthood starts.

What being messy could be saying about your mental health - Insider - 0 views

  • Here's what a messy room can tell you about your mental health
  • If you're normally neat, a messy room could be a sign that your mental health is in a tough spot.
  • If the mess bothers you or you're worried, you may want to speak with a qualified professional.
  • ...11 more annotations...
  • But if the mess doesn’t bother you, it’s probably no big deal.
  • Having a messy room doesn't necessarily mean that there's anything else going on in terms of your mental health, but, in some cases, it can indicate something more serious.
  • Several of the criteria for a depression diagnosis — hopelessness, fatigue, and lack of concentration — can all play a role in why your messy room is in the state it's in.
  • If you're feeling a little less than hopeful, you might have a hard time understanding why you should even bother to clean up or organize things since, from where you're standing, everything seems to be going wrong anyway.
  • "Sometimes when life feels out of control or stressful other areas of your life get affected one being your working or living space,"
  • "So you can intend to put things in order in your room and never find the concentration or the energy to get around to it because you have so many other things going on.
  • Even if you don't recognize that you fit the criteria for an official diagnosis of depression (or just plain don't fit the criteria) if you're overwhelmed or have a lot going on in your head, cleaning your room can still be a major challenge.
  • Lack of concentration, too, can make the actual task of cleaning up your room impossible.
  • "If you're depressed or overwhelmed with life you may feel you don't have time to clean/organize, you may feel you don't deserve a clean space or you may be so preoccupied with other things you don't even notice how messy your room has become."
  • But just because your room is messy, doesn't mean you have depression, of course.
  • "If you're constantly hoping to stay more organized and keep the room clean, but find yourself unable to do it for other reasons, that's when you know that it's time for an intervention,"

Here is the news - but only if Facebook thinks you need to know | John Naughton | Opini... - 0 views

  • power essentially comes in three varieties: the ability to compel people to do what they don’t want to do; the capability to stop them doing what they want to do; and the power to shape the way they think
  • This last is the kind of power exercised by our mass media. They can shape the public (and therefore the political) agenda by choosing the news that people read, hear or watch; and they can shape the ways in which that news is presented.
  • For a long time, Google was the 800lb gorilla in this domain, because its dominance of search determined what people could find in the unimaginable wastelands of cyberspace
  • ...7 more annotations...
  • search could be – and was – personalised, because Google’s algorithms could figure out what each user was most likely to be interested in, and therefore what kinds of information would be most relevant for her or him. So, imperceptibly, but inexorably over time, we have come to live in what Eli Pariser christened a “filter bubble”.
  • Before the internet, our problem with information was its scarcity. Now our problem is unmanageable abundance. So now the scarce resources are attention and time, over which a vicious war has broken out between traditional media and the internet-based upstarts.
  • YouTube has a billion users, half of whom access it via mobile devices. The average time spent on the site is 40 minutes. Facebook now claims to have 1.65 billion monthly active users, who spend on average 50 minutes a day on its services. So if Google is an 800lb gorilla, Facebook is a megaton King Kong.
  • Competition for attention and time is a zero-sum game that traditional media are losing. In desperation, they are trying both to appease Facebook and to harness its hold on people’s attention
  • In doing so, they have entered into a truly Faustian bargain. Because while publishers can without difficulty ship their stuff to Instant Articles, they cannot control which ones Facebook users actually get to see. This is because users’ news feeds are determined by Facebook’s machine-learning algorithms that try to guess what each user would like to see (and what might dispose them to click on an advertisement).
  • when you ask – as Professor George Brock memorably did – whether Mark Zuckerberg and his satraps understand that they have acquired editorial responsibilities, they look blank. Facebook is not a publisher, they explain, merely a “platform”. And, besides, no humans are involved in curating users’ news feeds: it’s all done by algorithms and is therefore neutral. In other words: nothing to see here; move on.
  • Any algorithm that has to make choices has criteria that are specified by its designers. And those criteria are expressions of human values. Engineers may think they are “neutral”, but long experience has shown us they are babes in the woods of politics, economics and ideology.

Grayson Perry's Reith Lectures: Who decides what makes art good? - FT.com - 0 views

  • I think this is one of the most burning issues around art – how do we tell if something is good? And who tells us that it’s good?
  • many of the methods of judging are very problematic and many of the criteria used to assess art are conflicting. We have financial value, popularity, art historical significance, or aesthetic sophistication. All these things could be at odds with each other.
  • A visitor to an exhibition like the Hockney one, if they were judging the quality of the art, might use a word like “beauty”. Now, if you use that kind of word in the art world, be very careful. There will be sucking of teeth and mournful shaking of heads because their hero, the artist Marcel Duchamp, of “urinal” fame, he said, “Aesthetic delectation is the danger to be avoided.” In the art world sometimes it can feel as if to judge something on its beauty, on its aesthetic merits, is as if you’re buying into something politically incorrect, into sexism, into racism, colonialism, class privilege. It almost feels it’s loaded, because where does our idea of beauty come from?
  • ...16 more annotations...
  • beauty is very much about familiarity and it’s reinforcing an idea we have already. It’s like when we go on holiday, all we really want to do is take the photograph that we’ve seen in the brochure. Because our idea of beauty is constructed, by family, friends, education, nationality, race, religion, politics, all these things
  • I have found the 21st-century version of the Venetian secret and it is a mathematical formula. What you do, you get a half-decent, non-offensive kind of idea, then you times it by the number of studio assistants, and then you divide it with an ambitious art dealer, and that equals number of oligarchs and hedge fund managers in the world.
  • the nearest we have to an empirical measure of art that actually does exist is the market. By that reckoning, Cézanne’s “Card Players” is the most beautiful lovely painting in the world. I find it a little bit clunky-kitsch but that’s me. It’s worth $260m.
  • The opposite arguments are that it’s art for art’s sake and that’s a very idealistic position to take. Clement Greenberg, a famous art critic in the 1950s, said that art will always be tied to money by an umbilical cord of gold, either state money or market money. I’m pragmatic about it: one of my favourite quotes is you’ll never have a good art career unless your work fits into the elevator of a New York apartment block.
  • there’s one thing about that red painting that ends up in Sotheby’s. It’s not just any old red painting. It is a painting that has been validated. This is an important word in the art world and the big question is: who validates? There is quite a cast of characters in this validation chorus that will kind of decide what is good art. They are a kind of panel, if you like, that decides on what is good quality, what are we going to end up looking at?
  • They include artists, teachers, dealers, collectors, critics, curators, the media, even the public maybe. And they form this lovely consensus around what is good art.
  • there were four stages to the rise of an artist. Peers, serious critics and collectors, dealers, then the public.
  • Another member of that cast of validating characters is the collectors. In the 1990s, if Charles Saatchi just put his foot over the threshold of your exhibition, that was it. The media was agog and he would come in and Hoover it up. You do want the heavyweight collector to buy your work because that gives it kudos. You don’t want a tacky one who is just buying it to glitz up their hallway.
  • The next part of this chorus of validation are the dealers. A good dealer brand has a very powerful effect on the reputation of the artist; they form a part of placing the work. This is a slightly mysterious process that many people don’t quite understand but a dealer will choose where your work goes so it gains the brownie points, so the buzz around it goes up.
  • now, of course, galleries like the Tate Modern want a big name because visitor numbers, in a way, are another empirical measure of quality. So perhaps at the top of the tree of the validation cast are the curators, and in the past century they have probably become the most powerful giver-outers of brownie points in the art world.
  • ach of the encounters with these members of the cast of validation bestows upon the work, and on the artist, a patina, and what makes that patina is all these hundreds of little conversations and reviews and the good prices over time. These are the filters that pass a work of art through into the canon.
  • So what does this lovely consensus, that all these people are bestowing on this artwork, that anoints it with the quality that we all want, boil down to? I think in many ways what it boils down to is seriousness. That’s the most valued currency in the art world.
  • The whole idea of quality now seems to be contested, as if you’re buying into the language of the elite by saying, “Oh, that’s very good.” How you might judge this work is really problematic because to say it’s not beautiful is to put the wrong kind of criteria on it. You might say, “Oh, it’s dull!” [And people will say] “Oh, you’re just not understanding it with the right terms.” So I think, “Well, how do we judge these things?” Because a lot of them are quite politicised. There’s quite a right-on element to them, so do we judge them on how ethical they are, or how politically right-on they are?
  • What I am attempting to explain is how the art we see in museums and in galleries around the world, and in biennales – how it ends up there, how it gets chosen. In the end, if enough of the right people think it’s good, that’s all there is to it. But, as Alan Bennett said when he was a trustee of the National Gallery, they should put a big sign up outside saying: “You don’t have to like it all.”
  • Or then again I might say, “Well, what do I judge them against?” Do I judge them against government policy? Do I judge them against reality TV? Because that does participation very well. So, in the end, what do we do? What happens to this sort of art when it doesn’t have validation? What is it left with? It’s left with popularity.
  • Then, of course, the next group of people we might think about in deciding what is good art is the public. Since the mid-1990s, art has got a lot more media attention. But popularity has always been a quite dodgy quality [to have]. The highbrow critics will say, “Oh, he’s a bit of a celebrity,” and they turn their noses up about people who are well known to the public

NIH to Cut Back on Chimp Research | The Scientist Magazine® - 0 views

  • announced plans this morning (June 26) to accept and implement changes to its chimpanzee research program
  • “This represents a significant, positive, albeit incremental step forward
  • “Americans have benefitted greatly from the chimpanzees’ service to biomedical research, but new scientific methods and technologies have rendered their use in research largely unnecessary,” said Collins in a statement. “After extensive consideration with the expert guidance of many, I am confident that greatly reducing their use in biomedical research is scientifically sound and the right thing to do.”

  • establishing a review panel to consider the use of chimpanzees in future research that satisfies criteria laid by the IOM report, such as minimally invasive projects involving genomic and behavioral research; winding down research projects that do not meet IOM’s criteria; and providing ethologically appropriate housing facilities that attempt to mimic the animals’ natural settings.
  • Funds available to the NIH for retiring chimpanzees have been nearly depleted—only $800,000 of the $30 million allocated under the CHIMP Act of 2002 is still available. The agency will be seeking additional funds from Congress to implement its chimp retirement plan.
  • “It is crucial now to ensure that the release of hundreds of chimpanzees to sanctuary becomes a reality.”

Teachers - Will We Ever Learn? - NYTimes.com - 0 views

  • America’s overall performance in K-12 education remains stubbornly mediocre.
  • The debate over school reform has become a false polarization
  • teaching is a complex activity that is hard to direct and improve from afar. The factory model is appropriate to simple work that is easy to standardize; it is ill suited to disciplines like teaching that require considerable skill and discretion.
  • ...13 more annotations...
  • In the nations that lead the international rankings — Singapore, Japan, South Korea, Finland, Canada — teachers are drawn from the top third of college graduates, rather than the bottom 60 percent as is the case in the United States. Training in these countries is more rigorous, more tied to classroom practice and more often financed by the government than in America. There are also many fewer teacher-training institutions, with much higher standards.
  • By these criteria, American education is a failed profession. There is no widely agreed-upon knowledge base, training is brief or nonexistent, the criteria for passing licensing exams are much lower than in other fields, and there is little continuous professional guidance. It is not surprising, then, that researchers find wide variation in teaching skills across classrooms; in the absence of a system devoted to developing consistent expertise, we have teachers essentially winging it as they go along, with predictably uneven results.
  • Teaching requires a professional model, like we have in medicine, law, engineering, accounting, architecture and many other fields. In these professions, consistency of quality is created less by holding individual practitioners accountable and more by building a body of knowledge, carefully training people in that knowledge, requiring them to show expertise before they become licensed, and then using their professions’ standards to guide their work.
  • Teachers in leading nations’ schools also teach much less than ours do. High school teachers provide 1,080 hours per year of instruction in America, compared with fewer than 600 in South Korea and Japan, where the balance of teachers’ time is spent collaboratively on developing and refining lesson plans
  • These countries also have much stronger welfare states; by providing more support for students’ social, psychological and physical needs, they make it easier for teachers to focus on their academic needs.
  • hese elements create a virtuous cycle: strong academic performance leads to schools with greater autonomy and more public financing, which in turn makes education an attractive profession for talented people.
  • In America, both major teachers’ unions and the organization representing state education officials have, in the past year, called for raising the bar for entering teachers; one of the unions, the American Federation of Teachers, advocates a “bar exam.”
  • Ideally the exam should not be a one-time paper-and-pencil test, like legal bar exams, but a phased set of milestones to be attained over the first few years of teaching. Akin to medical boards, they would require prospective teachers to demonstrate subject and pedagogical knowledge — as well as actual teaching skill.
  • We let doctors operate, pilots fly, and engineers build because their fields have developed effective ways of certifying that they can do these things. Teaching, on the whole, lacks this specialized knowledge base; teachers teach based mostly on what they have picked up from experience and from their colleagues.
  • other fields spend 5 percent to 15 percent of their budgets on research and development, while in education, it is around 0.25 percent
  • Education-school researchers publish for fellow academics; teachers develop practical knowledge but do not evaluate or share it; commercial curriculum designers make what districts and states will buy, with little regard for quality.
  • Early- to mid-career teachers need time to collaborate and explore new directions — having mastered the basics, this is the stage when they can refine their skills. The system should reward master teachers with salaries commensurate with leading professionals in other fields.
  • research suggests that the labels don’t matter — there are good and bad programs of all types, including university-based ones. The best programs draw people who majored as undergraduates in the subjects they wanted to teach; focus on extensive clinical practice rather than on classroom theory; are selective in choosing their applicants rather than treating students as a revenue stream; and use data about how their students fare as teachers to assess and revise their practice.

The Science of Snobbery: How We're Duped Into Thinking Fancy Things Are Better - The At... - 0 views

  • Expert judges and amateurs alike claim to judge classical musicians based on sound. But Tsay’s research suggests that the original judges, despite their experience and expertise, judged the competition (which they heard and watched live) based on visual information, just as amateurs do.
  • just like with classical music, we do not appraise wine in the way that we expect. 
  • Priceonomics revisited this seemingly damning research: the lack of correlation between wine enjoyment and price in blind tastings, the oenology students tricked by red food dye into describing a white wine like a red, a distribution of medals at tastings equivalent to what one would expect from pure chance, the grand crus described like cheap wines and vice-versa when the bottles are switched.
  • ...26 more annotations...
  • Taste does not simply equal your taste buds. It draws on information from all our senses as well as context. As a result, food is susceptible to the same trickery as wine. Adding yellow food dye to vanilla pudding leads people to experience a lemony taste. Diners eating in the dark at a chic concept restaurant confuse veal for tuna. Branding, packaging, and price tags are equally important to enjoyment. Cheap fish is routinely passed off as its pricier cousins at seafood and sushi restaurants. 
  • Just like with wine and classical music, we often judge food based on very different criteria than what we claim. The result is that our perceptions are easily skewed in ways we don’t anticipate. 
  • What does it mean for wine that presentation so easily trumps the quality imbued by being grown on premium Napa land or years of fruitful aging? Is it comforting that the same phenomenon is found in food and classical music, or is it a strike against the authenticity of our enjoyment of them as well? How common must these manipulations be until we concede that the influence of the price tag of a bottle of wine or the visual appearance of a pianist is not a trick but actually part of the quality?
  • To answer these questions, we need to investigate the underlying mechanism that leads us to judge wine, food, and music by criteria other than what we claim to value. And that mechanism seems to be the quick, intuitive judgments our minds unconsciously make
  • this unknowability also makes it easy to be led astray when our intuition makes a mistake. We may often be able to count on the price tag or packaging of food and wine for accurate information about quality. But as we believe that we’re judging based on just the product, we fail to recognize when presentation manipulates our snap judgments.
  • Participants were just as effective when watching 6 second video clips and when comparing their ratings to ratings of teacher effectiveness as measured by actual student test performance. 
  • The power of intuitive first impressions has been demonstrated in a variety of other contexts. One experiment found that people predicted the outcome of political elections remarkably well based on silent 10 second video clips of debates - significantly outperforming political pundits and predictions made based on economic indicators.
  • In a real world case, a number of art experts successfully identified a 6th century Greek statue as a fraud. Although the statue had survived a 14 month investigation by a respected museum that included the probings of a geologist, they instantly recognized something was off. They just couldn’t explain how they knew.
  • Cases like this represent the canon behind the idea of the “adaptive unconscious,” a concept made famous by journalist Malcolm Gladwell in his book Blink. The basic idea is that we constantly, quickly, and unconsciously do the equivalent of judging a book by its cover. After all, a cover provides a lot of relevant information in a world in which we don’t have time to read every page.
  • Gladwell describes the adaptive unconscious as “a kind of giant computer that quickly and quietly processes a lot of the data we need in order to keep functioning as human beings.”
  • In a famous experiment, psychologist Nalini Ambady provided participants in an academic study with 30 second silent video clips of a college professor teaching a class and asked them to rate the effectiveness of the professor.
  • In follow up experiments, Chia-Jung Tsay found that those judging musicians’ auditions based on visual cues were not giving preference to attractive performers. Rather, they seemed to look for visual signs of relevant characteristics like passion, creativity, and uniqueness. Seeing signs of passion is valuable information. But in differentiating between elite performers, it gives an edge to someone who looks passionate over someone whose play is passionate
  • Outside of these more eccentric examples, it’s our reliance on quick judgments, and ignorance of their workings, that cause people to act on ugly, unconscious biases
  • It’s also why - from a business perspective - packaging and presentation is just as important as the good or service on offer. Why marketing is just as important as product. 
  • Gladwell ends Blink optimistically. By paying closer attention to our powers of rapid cognition, he argues, we can avoid its pitfalls and harness its powers. We can blindly audition musicians behind a screen, look at a piece of art devoid of other context, and pay particular attention to possible unconscious bias in our performance reports.
  • But Gladwell’s success in demonstrating how the many calculations our adaptive unconscious performs without our awareness undermines his hopeful message of consciously harnessing its power.
  • As a former world-class tennis player and coach of over 50 years, Braden is a perfect example of the ideas behind thin slicing. But if he can’t figure out what his unconscious is up to when he recognizes double faults, why should anyone else expect to be up to the task?
  • flawed judgment in fields like medicine and investing has more serious consequences. The fact that expertise is so tricky leads psychologist Daniel Kahneman to assert that most experts should seek the assistance of statistics and algorithms in making decisions.
  • In his book Thinking, Fast and Slow, he describes our two modes of thought: System 1, like the adaptive unconscious, is our “fast, instinctive, and emotional” intuition. System 2 is our “slower, more deliberative, and more logical” conscious thought. Kahneman believes that we often leave decisions up to System 1 and generally place far “too much confidence in human judgment” due to the pitfalls of our intuition described above.
  • Not every judgment will be made in a field that is stable and regular enough for an algorithm to help us make judgments or predictions. But in those cases, he notes, “Hundreds of studies have shown that wherever we have sufficient information to build a model, it will perform better than most people.”
  • Experts can avoid the pitfalls of intuition more easily than laypeople. But they need help too, especially as our collective confidence in expertise leads us to overconfidence in their judgments. 
  • This article has referred to the influence of price tags and context on products and experiences like wine and classical music concerts as tricks that skew our perception. But maybe we should consider them a real, actual part of the quality.
  • Losing ourselves in a universe of relativism, however, will lead us to miss out on anything new or unique. Take the example of the song “Hey Ya!” by Outkast. When the music industry heard it, they felt sure it would be a hit. When it premiered on the radio, however, listeners changed the channel. The song sounded too dissimilar from songs people liked, so they responded negatively. 
  • It took time for people to get familiar with the song and realize that they enjoyed it. Eventually “Hey Ya!” became the hit of the summer.
  • Many boorish people talking about the ethereal qualities of great wine probably can't even identify cork taint because their impressions are dominated by the price tag and the wine label. But the classic defense of wine - that you need to study it to appreciate it - is also vindicated. The open question - which is both editorial and empiric - is what it means for the industry that constant vigilance and substantial study is needed to dependably appreciate wine for the product quality alone. But the questions is relevant to the enjoyment of many other products and experiences that we enjoy in life.
  • Maybe the most important conclusion is to not only recognize the fallibility of our judgments and impressions, but to recognize when it matters, and when it doesn’t

An Existential Problem in the Search for Alien Life - The Atlantic - 0 views

  • The fact is, we still don’t know what life is.
  • since the days of Aristotle, scientists and philosophers have struggled to draw a precise line between what is living and what is not, often returning to criteria such as self-organization, metabolism, and reproduction but never finding a definition that includes, and excludes, all the right things.
  • If you say life consumes fuel to sustain itself with energy, you risk including fire; if you demand the ability to reproduce, you exclude mules. NASA hasn’t been able to do better than a working definition: “Life is a self-sustaining chemical system capable of Darwinian evolution.”
  • ...20 more annotations...
  • it lacks practical application. If humans found something on another planet that seemed to be alive, how much time would we have to sit around and wait for it to evolve?
  • The only life we know is life on Earth. Some scientists call this the n=1 problem, where n is the number of examples from which we can generalize.
  • Cronin studies the origin of life, also a major interest of Walker’s, and it turned out that, when expressed in math, their ideas were essentially the same. They had both zeroed in on complexity as a hallmark of life. Cronin is devising a way to systematize and measure complexity, which he calls Assembly Theory.
  • What we really want is more than a definition of life. We want to know what life, fundamentally, is. For that kind of understanding, scientists turn to theories. A theory is a scientific fundamental. It not only answers questions, but frames them, opening new lines of inquiry. It explains our observations and yields predictions for future experiments to test.
  • Consider the difference between defining gravity as “the force that makes an apple fall to the ground” and explaining it, as Newton did, as the universal attraction between all particles in the universe, proportional to the product of their masses and so on. A definition tells us what we already know; a theory changes how we understand things.
  • the potential rewards of unlocking a theory of life have captivated a clutch of researchers from a diverse set of disciplines. “There are certain things in life that seem very hard to explain,” Sara Imari Walker, a physicist at Arizona State University who has been at the vanguard of this work, told me. “If you scratch under the surface, I think there is some structure that suggests formalization and mathematical laws.”
  • Walker doesn’t think about life as a biologist—or an astrobiologist—does. When she talks about signs of life, she doesn’t talk about carbon, or water, or RNA, or phosphine. She reaches for different examples: a cup, a cellphone, a chair. These objects are not alive, of course, but they’re clearly products of life. In Walker’s view, this is because of their complexity. Life brings complexity into the universe, she says, in its own being and in its products, because it has memory: in DNA, in repeating molecular reactions, in the instructions for making a chair.
  • He measures the complexity of an object—say, a molecule—by calculating the number of steps necessary to put the object’s smallest building blocks together in that certain way. His lab has found, for example, when testing a wide range of molecules, that those with an “assembly number” above 15 were exclusively the products of life. Life makes some simpler molecules, too, but only life seems to make molecules that are so complex.
  • I reach for the theory of gravity as a familiar parallel. Someone might ask, “Okay, so in terms of gravity, where are we in terms of our understanding of life? Like, Newton?” Further back, further back, I say. Walker compares us to pre-Copernican astronomers, reliant on epicycles, little orbits within orbits, to make sense of the motion we observe in the sky. Cleland has put it in terms of chemistry, in which case we’re alchemists, not even true chemists yet
  • Walker’s whole notion is that it’s not only theoretically possible but genuinely achievable to identify something smaller—much smaller—that still nonetheless simply must be the result of life. The model would, in a sense, function like biosignatures as an indication of life that could be searched for. But it would drastically improve and expand the targets.
  • Walker would use the theory to predict what life on a given planet might look like. It would require knowing a lot about the planet—information we might have about Venus, but not yet about a distant exoplanet—but, crucially, would not depend at all on how life on Earth works, what life on Earth might do with those materials.
  • Without the ability to divorce the search for alien life from the example of life we know, Walker thinks, a search is almost pointless. “Any small fluctuations in simple chemistry can actually drive you down really radically different evolutionary pathways,” she told me. “I can’t imagine [life] inventing the same biochemistry on two worlds.”
  • Walker’s approach is grounded in the work of, among others, the philosopher of science Carol Cleland, who wrote The Quest for a Universal Theory of Life.
  • she warns that any theory of life, just like a definition, cannot be constrained by the one example of life we currently know. “It’s a mistake to start theorizing on the basis of a single example, even if you’re trying hard not to be Earth-centric. Because you’re going to be Earth-centric,” Cleland told me. In other words, until we find other examples of life, we won’t have enough data from which to devise a theory. Abstracting away from Earthliness isn’t a way to be agnostic, Cleland argues. It’s a way to be too abstract.
  • Cleland calls for a more flexible search guided by what she calls “tentative criteria.” Such a search would have a sense of what we’re looking for, but also be open to anomalies that challenge our preconceptions, detections that aren’t life as we expected but aren’t familiar not-life either—neither a flower nor a rock
  • it speaks to the hope that exploration and discovery might truly expand our understanding of the cosmos and our own world.
  • The astrobiologist Kimberley Warren-Rhodes studies life on Earth that lives at the borders of known habitability, such as in Chile’s Atacama Desert. The point of her experiments is to better understand how life might persist—and how it might be found—on Mars. “Biology follows some rules,” she told me. The more of those rules you observe, the better sense you have of where to look on other worlds.
  • In this light, the most immediate concern in our search for extraterrestrial life might be less that we only know about life on Earth, and more that we don’t even know that much about life on Earth in the first place. “I would say we understand about 5 percent,” Warren-Rhodes estimates of our cumulative knowledge. N=1 is a problem, and we might be at more like n=.05.
  • who knows how strange life on another world might be? What if life as we know it is the wrong life to be looking for?
  • We understand so little, and we think we’re ready to find other life?

  • So you’re happily tweeting away as your Google self-driving car crosses a bridge, its speed precisely synced to the 50 m.p.h. limit. A group of frisky schoolchildren is also heading across the bridge, on the pedestrian walkway. Suddenly, there’s a tussle, and three of the kids are pushed into the road, right in your vehicle’s path. Your self-driving car has a fraction of a second to make a choice: Either it swerves off the bridge, possibly killing you, or it runs over the children. What does the Google algorithm tell it to do?
  • As we begin to have computer-controlled cars, robots, and other machines operating autonomously out in the chaotic human world, situations will inevitably arise in which the software has to choose between a set of bad, even horrible, alternatives. How do you program a computer to choose the lesser of two evils? What are the criteria, and how do you weigh them?
  • Since we humans aren’t very good at codifying responses to moral dilemmas ourselves, particularly when the precise contours of a dilemma can’t be predicted ahead of its occurrence, programmers will find themselves in an extraordinarily difficult situation. And one assumes that they will carry a moral, not to mention a legal, burden for the code they write.

What Is College For? (Part 2) - NYTimes.com - 0 views

  • How, exactly, does college prepare students for the workplace? For most jobs, it provides basic intellectual skills: the ability to understand relatively complex instructions, to write and speak clearly and cogently, to evaluate options critically. Beyond these intellectual skills, earning a college degree shows that you have the “moral qualities” needed for most jobs: you have (to put it a bit cynically), for a period of four years and with relatively little supervision, deferred to authority, met deadlines and carried out difficult tasks even when you found them pointless and boring.
  • This sort of intellectual and moral training, however, does not require studying with experts doing cutting-edge work on, say, Homeric poetry, elementary particle theory or the philosophy of Kant. It does not, that is, require the immersion in the world of intellectual culture that a college faculty is designed to provide. It is, rather, the sort of training that ought to result from good elementary and high school education.
  • students graduating from high school should, to cite one plausible model, be able to read with understanding classic literature (from, say, Austen and Browning to Whitman and Hemingway) and write well-organized and grammatically sound essays; they should know the basic outlines of American and European history, have a good beginner’s grasp of at least two natural sciences as well as pre-calculus mathematics, along with a grounding in a foreign language.

  • Is it really possible to improve grade school and high school teaching to the level I’m suggesting? Yes, provided we employ the same sort of selection criteria for pre-college teachers as we do for other professionals such as doctors, lawyers and college professors. In contrast to other professions, teaching is not now the domain of the most successful students — quite the contrary. I’ve known many very bright students who had an initial interest in such teaching but soon realized that there is no comparison in terms of salary, prestige and working conditions.
  • Given this transformation in pre-college education, we could expect it to provide basic job-training for most students. At that point, we would still face a fundamental choice regarding higher education. We could see it as a highly restricted enterprise, educating only professionals who require advanced specialized skills. Correspondingly, only such professionals would have access to higher education as a locus of intellectual culture.
  • On the other hand, we could — as I would urge — see college as the entrée to intellectual culture for everyone who is capable of and interested in working at that level of intellectual engagement
  • Raising high school to the level I am proposing and opening college to everyone who will profit from it would be an expensive enterprise. We would need significant government support to ensure that all students receive an education commensurate with their abilities and aspirations, regardless of family resources. But the intellectual culture of our citizens should be a primary part of our national well-being, not just the predilection of an eccentric elite. As such, it should be among our highest priorities.

How can we best assess the neuropsychological effects of violent video game play? | Pet... - 0 views

  • Every time a research paper about violent video games makes it into the news, it feels like we’re in a time loop. Any claims that the study makes about the potential positive or (usually) negative effects of playing games tend to get over-egged to the point of ridiculousness.
  • At best, the measures of aggression that are used in such work are unstandardised; at worst, the field has been shown to be riddled with basic methodological and analytical flaws. These problems are further compounded by entrenched ideologies and a reluctance from some researchers to even talk to their ‘adversaries’, let alone discuss the potential for adversarial collaborations
  • All of this means that we’re stuck at an impasse with violent video games research; it feels like we’re no more clued up on what the actual behavioural effects are now than, say, five or ten years ago.

  • In stage 1, they submit the introduction, methods, proposed analysis, and if necessary, pilot data. This manuscript then goes through the usual peer review process, and is assessed on criteria such as the soundness of the methods and analysis, and overall plausibility of the stated hypotheses.
  • Once researchers have passed through stage 1, they can then move on to data collection. In stage 2, they then submit the full manuscript – the introduction and agreed methods from stage 1, plus results and discussion sections. The results must include the outcome of the analyses agreed in stage 1, but the researchers are allowed to include additional analyses in a separate, ‘exploratory’ section (as long as they are justified).
  • Pre-registering scientific articles in this way helps to protect against a number of undesirable practices (such as p-hacking and HARKing) that can exaggerate statistical findings and make non-existent effects seem real. While this is a problem across psychology generally, it is a particularly extreme problem for violent video game research.
  • By outlining the intended methods and analysis protocols beforehand, Registered Reports protect against these problems, as the review process concentrates on the robustness of the proposed methods. And Registered Reports offer an additional advantage: because manuscripts are never accepted based on the outcome of the data analysis, the process is immune to researcher party lines. It doesn’t matter which research ‘camp’ you are in; your data – and just as importantly, your methods - will speak for themselves.

If Evolution Has Implications for Religion, Can We Justify Teaching It in Public School... - 0 views

  • Evolutionary biology is a science, so it can be legally taught in public schools when it's treated as a science and isn't promoted as a support for atheism or materialism.

  • Do the larger religious (or anti-religious) implications of a scientific theory make it inadmissible for instruction in public schools? They shouldn't.
  • just because we're declaring the teaching of evolution to be constitutional doesn't mean we that it has no connections to religion
  • while it may sound odd to hear that we can (sometimes) declare something constitutional to teach in public schools even though it touches upon religion, there's good legal precedent for such a finding.
  • a government policy establishes religion if its "principal or primary effect" is one that "advances or inhibits" religion.
  • the statute must have a secular legislative purpose; second, its principal or primary effect must be one that neither advances nor inhibits religion; finally, the statute must not foster an excessive government entanglement with religion
  • a government policy is unconstitutional if it has a "primary" or "principal" effect that advances (or inhibits) religion. However, in light of this second part, the Supreme Court has also developed a legal doctrine called the "incidental effects" or "secondary effects" doctrine which says that government law or policy may have "secondary" or "incidental" effects that touch upon religion and not violate the Establishment Clause.
  • Secondary effects that touch upon religion are not constitutionally fatal.
  • the Court held in Lynch v. Donnelly that "not every law that confers an indirect, remote, or incidental benefit upon [religion] is, for that reason alone, constitutionally invalid"
  • if government aid "is allocated on the basis of neutral, secular criteria that neither favor nor disfavor religion, and is made available to both religious and secular beneficiaries on a nondiscriminatory basis," then any effects upon religion are merely incidental.
  • evolutionary biology is based upon science, when we teach it as a science, the primary effect is to advance scientific knowledge.
  • a scientific theory like evolution does speak to ultimate questions about origins, which are also addressed by religion
  • it certainly touches upon religious questions. But when we discuss Darwinian evolution strictly on a scientific level, any effects upon religion are "secondary" or "incidental" compared to their primary effect of advancing scientific knowledge.
  • if creation science were a scientific theory, it could have been taught because any its touching upon religion would have been a secondary effect
  • approach was also followed in Crowley v. Smithsonian Institution, where a federal judge rejected arguments that Smithsonian exhibits on evolution established "secular humanism" because the "impact [on religion] is at most incidental to the primary effect of presenting a body of scientific knowledge"
  • Because evolution is based upon science, any effects upon religion would not bar its teaching.
  • [I]f a theory has scientific value and evidence to support it, its primary effect would be to advance knowledge of the natural world, not to advance religion
  • ultimate goal of schools is to educate students. Where a theory has scientific value and supporting evidence, it provides a basis for knowledge. Whether it coincidentally advances religion should not matter.
  • one can legally justify teaching evolution while being sensitive to the fact that it has larger implications that touch upon the religious beliefs of many Americans.
  • best of both worlds. It allows science to be taught in the science classroom while respecting the beliefs of people who have religious objections to evolution.

A Most Valuable Democrat - NYTimes.com - 1 views

  • As Ezra Klein of The Washington Post noted recently, this turned out to be one of the most consequential decisions Obama and Reid made. If Lieberman had not been welcomed back by the Democrats, there might not have been a 60th vote for health care reform, and it would have failed. There certainly would have been no victory for “don’t ask, don’t tell” repeal without Lieberman’s tireless work and hawkish credentials. The Kerry-Lieberman climate bill came closer to passage than any other energy bill. Lieberman also provided crucial support or a swing vote for the Lilly Ledbetter Fair Pay Act, the stimulus bill, the banking bill, the unemployment extension and several other measures.
  • These policy makers are judging Lieberman by the criteria Max Weber called the “ethic of responsibility” — who will produce the best consequences. Some of the activists are judging him by what Weber called an “ethic of intention” — who has the purest and most uncompromising heart.

Watson Still Can't Think - NYTimes.com - 0 views

  • Fish argued that Watson “does not come within a million miles of replicating the achievements of everyday human action and thought.” In defending this claim, Fish invoked arguments that one of us (Dreyfus) articulated almost 40 years ago in “What Computers Can’t Do,” a criticism of 1960s and 1970s style artificial intelligence.
  • At the dawn of the AI era the dominant approach to creating intelligent systems was based on finding the right rules for the computer to follow.
  • GOFAI, for Good Old Fashioned Artificial Intelligence.
  • ...12 more annotations...
  • For constrained domains the GOFAI approach is a winning strategy.
  • there is nothing intelligent or even interesting about the brute force approach.
  • the dominant paradigm in AI research has largely “moved on from GOFAI to embodied, distributed intelligence.” And Faustus from Cincinnati insists that as a result “machines with bodies that experience the world and act on it” will be “able to achieve intelligence.”
  • The new, embodied paradigm in AI, deriving primarily from the work of roboticist Rodney Brooks, insists that the body is required for intelligence. Indeed, Brooks’s classic 1990 paper, “Elephants Don’t Play Chess,” rejected the very symbolic computation paradigm against which Dreyfus had railed, favoring instead a range of biologically inspired robots that could solve apparently simple, but actually quite complicated, problems like locomotion, grasping, navigation through physical environments and so on. To solve these problems, Brooks discovered that it was actually a disadvantage for the system to represent the status of the environment and respond to it on the basis of pre-programmed rules about what to do, as the traditional GOFAI systems had. Instead, Brooks insisted, “It is better to use the world as its own model.”
  • although they respond to the physical world rather well, they tend to be oblivious to the global, social moods in which we find ourselves embedded essentially from birth, and in virtue of which things matter to us in the first place.
  • the embodied AI paradigm is irrelevant to Watson. After all, Watson has no useful bodily interaction with the world at all.
  • The statistical machine learning strategies that it uses are indeed a big advance over traditional GOFAI techniques. But they still fall far short of what human beings do.
  • “The illusion is that this computer is doing the same thing that a very good ‘Jeopardy!’ player would do. It’s not. It’s doing something sort of different that looks the same on the surface. And every so often you see the cracks.”
  • Watson doesn’t understand relevance at all. It only measures statistical frequencies. Because it is relatively common to find mismatches of this sort, Watson learns to weigh them as only mild evidence against the answer. But the human just doesn’t do it that way. The human being sees immediately that the mismatch is irrelevant for the Erie Canal but essential for Toronto. Past frequency is simply no guide to relevance.
  • The fact is, things are relevant for human beings because at root we are beings for whom things matter. Relevance and mattering are two sides of the same coin. As Haugeland said, “The problem with computers is that they just don’t give a damn.” It is easy to pretend that computers can care about something if we focus on relatively narrow domains — like trivia games or chess — where by definition winning the game is the only thing that could matter, and the computer is programmed to win. But precisely because the criteria for success are so narrowly defined in these cases, they have nothing to do with what human beings are when they are at their best.
  • Far from being the paradigm of intelligence, therefore, mere matching with no sense of mattering or relevance is barely any kind of intelligence at all. As beings for whom the world already matters, our central human ability is to be able to see what matters when.
  • But, as we show in our recent book, this is an existential achievement orders of magnitude more amazing and wonderful than any statistical treatment of bare facts could ever be. The greatest danger of Watson’s victory is not that it proves machines could be better versions of us, but that it tempts us to misunderstand ourselves as poorer versions of them.

  • They subscribed to moral systems — whether secular or religious — that recommended specific ways of being, and had specific structures of what is right and wrong, and had specific disciplines about how you might get better over time.
  • Meaningfulness tries to replace structures, standards and disciplines with self-regarding emotion. The ultimate authority of meaningful is the warm tingling we get when we feel significant and meaningful.
  • The philosophy of meaningfulness emerges in a culture in which there is no common moral vocabulary or framework. It emerges amid radical pluralism, when people don’t want to judge each other. Meaningfulness emerges when the fundamental question is, do we feel good?
  • Meaningfulness tries to replace moral systems with the emotional corona that surrounds acts of charity.
  • Because meaningfulness is built solely on an emotion, it is contentless and irreducible. Because it is built solely on emotion, it’s subjective and relativistic. You get meaning one way. I get meaning another way. Who is any of us to judge another’s emotion?
  • Because it’s based solely on sentiment, it is useless. There are no criteria to determine what kind of meaningfulness is higher. There’s no practical manual that would help guide each of us as we move from shallower forms of service to deeper ones. There is no hierarchy of values that would help us select, from among all the things we might do, that activity which is highest and best to do.
  • Because it’s based solely on emotion, it’s fleeting. When the sensations of meaningful go away then the cause that once aroused them gets dropped, too. Ennui floods in. Personal crisis follows. There’s no reliable ground.
  • If we look at the people in history who achieved great things — like Nelson Mandela or Albert Schweitzer or Abraham Lincoln — it wasn’t because they wanted to bathe luxuriously in their own sense of meaningfulness. They had objective and eternally true standards of justice and injustice. They were indignant when those eternal standards were violated.
  • Real moral systems are based on a balance of intellectual rigor and aroused moral sentiments.

Is Science Kind of a Scam? - The New Yorker - 1 views

  • No well-tested scientific concept is more astonishing than the one that gives its name to a new book by the Scientific American contributing editor George Musser, “Spooky Action at a Distance

  • ...29 more annotations...

  • fashion, temperament, zeitgeist, and sheer tenacity affected the debate, along with evidence and argument.
  • The certainty that spooky action at a distance takes place, Musser says, challenges the very notion of “locality,” our intuitive sense that some stuff happens only here, and some stuff over there. What’s happening isn’t really spooky action at a distance; it’s spooky distance, revealed through an action.
  • Why, then, did Einstein’s question get excluded for so long from reputable theoretical physics? The reasons, unfolding through generations of physicists, have several notable social aspects,
  • What started out as a reductio ad absurdum became proof that the cosmos is in certain ways absurd. What began as a bug became a feature and is now a fact.
  • The “indeterminacy” of the atom was, for younger European physicists, “a lesson of modernity, an antidote to a misplaced Enlightenment trust in reason, which German intellectuals in the 1920’s widely held responsible for their country’s defeat in the First World War.” The tonal and temperamental difference between the scientists was as great as the evidence they called on.
  • Musser explains that the big issue was settled mainly by being pushed aside. Generational imperatives trumped evidentiary ones. The things that made Einstein the lovable genius of popular imagination were also the things that made him an easy object of condescension. The hot younger theorists patronized him,
  • There was never a decisive debate, never a hallowed crucial experiment, never even a winning argument to settle the case, with one physicist admitting, “Most physicists (including me) accept that Bohr won the debate, although like most physicists I am hard pressed to put into words just how it was done.”
  • Arguing about non-locality went out of fashion, in this account, almost the way “Rock Around the Clock” displaced Sinatra from the top of the charts.
  • The same pattern of avoidance and talking-past and taking on the temper of the times turns up in the contemporary science that has returned to the possibility of non-locality.
  • the revival of “non-locality” as a topic in physics may be due to our finding the metaphor of non-locality ever more palatable: “Modern communications technology may not technically be non-local but it sure feels that it is.”
  • Living among distant connections, where what happens in Bangalore happens in Boston, we are more receptive to the idea of such a strange order in the universe.

  • science, then, a club like any other, with fetishes and fashions, with schemers, dreamers, and blackballed applicants? Is there a real demarcation to be made between science and every other kind of social activity
  • What was magic became mathematical and then mundane. “Magical” explanations, like spooky action, are constantly being revived and rebuffed, until, at last, they are reinterpreted and accepted. Instead of a neat line between science and magic, then, we see a jumpy, shifting boundary that keeps getting redrawn
  • Real-world demarcations between science and magic, Musser’s story suggests, are like Bugs’s: made on the move and as much a trap as a teaching aid.
  • In the past several decades, certainly, the old lines between the history of astrology and astronomy, and between alchemy and chemistry, have been blurred; historians of the scientific revolution no longer insist on a clean break between science and earlier forms of magic.
  • Where once logical criteria between science and non-science (or pseudo-science) were sought and taken seriously—Karl Popper’s criterion of “falsifiability” was perhaps the most famous, insisting that a sound theory could, in principle, be proved wrong by one test or another—many historians and philosophers of science have come to think that this is a naïve view of how the scientific enterprise actually works.
  • They see a muddle of coercion, old magical ideas, occasional experiment, hushed-up failures—all coming together in a social practice that gets results but rarely follows a definable logic.
  • Yet the old notion of a scientific revolution that was really a revolution is regaining some credibility.
  • David Wootton, in his new, encyclopedic history, “The Invention of Science” (Harper), recognizes the blurred lines between magic and science but insists that the revolution lay in the public nature of the new approach.
  • What killed alchemy was the insistence that experiments must be openly reported in publications which presented a clear account of what had happened, and they must then be replicated, preferably before independent witnesses.
  • Wootton, while making little of Popper’s criterion of falsifiability, makes it up to him by borrowing a criterion from his political philosophy. Scientific societies are open societies. One day the lunar tides are occult, the next day they are science, and what changes is the way in which we choose to talk about them.
  • Wootton also insists, against the grain of contemporary academia, that single observed facts, what he calls “killer facts,” really did polish off antique authorities
  • once we agree that the facts are facts, they can do amazing work. Traditional Ptolemaic astronomy, in place for more than a millennium, was destroyed by what Galileo discovered about the phases of Venus. That killer fact “serves as a single, solid, and strong argument to establish its revolution around the Sun, such that no room whatsoever remains for doubt,” Galileo wrote, and Wootton adds, “No one was so foolish as to dispute these claims.
  • everal things flow from Wootton’s view. One is that “group think” in the sciences is often true think. Science has always been made in a cloud of social networks.
  • There has been much talk in the pop-sci world of “memes”—ideas that somehow manage to replicate themselves in our heads. But perhaps the real memes are not ideas or tunes or artifacts but ways of making them—habits of mind rather than products of mind
  • Science isn’t a slot machine, where you drop in facts and get out truths. But it is a special kind of social activity, one where lots of different human traits—obstinacy, curiosity, resentment of authority, sheer cussedness, and a grudging readiness to submit pet notions to popular scrutiny—end by producing reliable knowledge
  • The claim that basic research is valuable because it leads to applied technology may be true but perhaps is not at the heart of the social use of the enterprise. The way scientists do think makes us aware of how we can think
