Opinion | Privacy Is Too Big to Understand - The New York Times - 1 views

  • There is “no single rhetorical approach likely to work on a given audience and none too dangerous to try. Any story that sticks is a good one,”

The Benefits of Character Education - The Atlantic - 0 views

  • five years in, I have come to understand what real character education looks like and what it can do for children. I can't imagine teaching in a school that does not have a hard-core commitment to character education, because I've seen what that education can mean to a child's emotional, moral, and intellectual development
  • From a practical perspective, it's simply easier to teach children who can exercise patience, self-control, and diligence, even when they would rather be playing outside - especially when they would rather be playing outside.
  • As the core virtues program uses examples to literature in order to illustrate character, I choose my texts accordingly. In my middle school Latin and English classes, we explore the concept of temperance through discussions of Achilles' impulsive rages, King Ozymandias' petulant demand that we "Look on my works, ye Mighty, and despair," Macbeth's bloody, "vaulting ambition, which o'erleaps itself and falls on the other."

  • Self-control itself does not make a kid smarter, or fitter, or more proficient at test-taking, but it's the essential skill hidden within all of these positive outcomes.
  • Character education is not old-fashioned, and it's not about bringing religion in to the classroom. Character education teaches children how to make wise decisions and act on them. Character is the "X factor" that experts in parenting and education have deemed integral to success, both in school and in life. Paul Tough, author of How Children Succeed, calls that character-based X factor "grit," while educational consultant Dr. Michele Borba calls it "moral intelligence.
  • Character education needs to be relevant. It needs to be woven in curriculum, not tacked on. We are such a trophy-, SAT-obsessed society, but if parents would recognize the value beyond the humanness, civility and ethics, they might get it."

How to Remember Everything You Want From Non-Fiction Books | by Eva Keiffenheim, MSc | Better Humans | Dec, 2020 | Medium - 0 views

  • A Bachelor’s degree taught me how to learn to ace exams. But it didn’t teach me how to learn to remember.
  • 65% to 80% of students answered “no” to the question “Do you study the way you do because somebody taught you to study that way?”
  • the most-popular Coursera course of all time: Dr. Barabara Oakley’s free course on “Learning how to Learn.” So did I. And while this course taught me about chunking, recalling, and interleaving
  • ...66 more annotations...
  • I learned something more useful: the existence of non-fiction literature that can teach you anything.
  • something felt odd. Whenever a conversation revolved around a serious non-fiction book I read, such as ‘Sapiens’ or ‘Thinking Fast and Slow,’ I could never remember much. Turns out, I hadn’t absorbed as much information as I’d believed. Since I couldn’t remember much, I felt as though reading wasn’t an investment in knowledge but mere entertainment.
  • When I opened up about my struggles, many others confessed they also can’t remember most of what they read, as if forgetting is a character flaw. But it isn’t.
  • It’s the way we work with books that’s flawed.
  • there’s a better way to read. Most people rely on techniques like highlighting, rereading, or, worst of all, completely passive reading, which are highly ineffective.
  • Since I started applying evidence-based learning strategies to reading non-fiction books, many things have changed. I can explain complex ideas during dinner conversations. I can recall interesting concepts and link them in my writing or podcasts. As a result, people come to me for all kinds of advice.
  • What’s the Architecture of Human Learning and Memory?
  • Human brains don’t work like recording devices. We don’t absorb information and knowledge by reading sentences.
  • we store new information in terms of its meaning to our existing memory
  • we give new information meaning by actively participating in the learning process — we interpret, connect, interrelate, or elaborate
  • To remember new information, we not only need to know it but also to know how it relates to what we already know.
  • Learning is dependent on memory processes because previously-stored knowledge functions as a framework in which newly learned information can be linked.”
  • Human memory works in three stages: acquisition, retention, and retrieval. In the acquisition phase, we link new information to existing knowledge; in the retention phase, we store it, and in the retrieval phase, we get information out of our memory.
  • Retrieval, the third stage, is cue dependent. This means the more mental links you’re generating during stage one, the acquisition phase, the easier you can access and use your knowledge.
  • we need to understand that the three phases interrelate
  • creating durable and flexible access to to-be-learned information is partly a matter of achieving a meaningful encoding of that information and partly a matter of exercising the retrieval process.”
  • Next, we’ll look at the learning strategies that work best for our brains (elaboration, retrieval, spaced repetition, interleaving, self-testing) and see how we can apply those insights to reading non-fiction books.
  • The strategies that follow are rooted in research from professors of Psychological & Brain Science around Henry Roediger and Mark McDaniel. Both scientists spent ten years bridging the gap between cognitive psychology and education fields. Harvard University Press published their findings in the book ‘Make It Stick.
  • #1 Elaboration
  • “Elaboration is the process of giving new material meaning by expressing it in your own words and connecting it with what you already know.”
  • Why elaboration works: Elaborative rehearsal encodes information into your long-term memory more effectively. The more details and the stronger you connect new knowledge to what you already know, the better because you’ll be generating more cues. And the more cues they have, the easier you can retrieve your knowledge.
  • How I apply elaboration: Whenever I read an interesting section, I pause and ask myself about the real-life connection and potential application. The process is invisible, and my inner monologues sound like: “This idea reminds me of…, This insight conflicts with…, I don’t really understand how…, ” etc.
  • For example, when I learned about A/B testing in ‘The Lean Startup,’ I thought about applying this method to my startup. I added a note on the site stating we should try it in user testing next Wednesday. Thereby the book had an immediate application benefit to my life, and I will always remember how the methodology works.
  • How you can apply elaboration: Elaborate while you read by asking yourself meta-learning questions like “How does this relate to my life? In which situation will I make use of this knowledge? How does it relate to other insights I have on the topic?”
  • While pausing and asking yourself these questions, you’re generating important memory cues. If you take some notes, don’t transcribe the author’s words but try to summarize, synthesize, and analyze.
  • #2 Retrieval
  • With retrieval, you try to recall something you’ve learned in the past from your memory. While retrieval practice can take many forms — take a test, write an essay, do a multiple-choice test, practice with flashcards
  • the authors of ‘Make It Stick’ state: “While any kind of retrieval practice generally benefits learning, the implication seems to be that where more cognitive effort is required for retrieval, greater retention results.”
  • Whatever you settle for, be careful not to copy/paste the words from the author. If you don’t do the brain work yourself, you’ll skip the learning benefits of retrieval
  • Retrieval strengthens your memory and interrupts forgetting and, as other researchers replicate, as a learning event, the act of retrieving information is considerably more potent than is an additional study opportunity, particularly in terms of facilitating long-term recall.
  • How I apply retrieval: I retrieve a book’s content from my memory by writing a book summary for every book I want to remember. I ask myself questions like: “How would you summarize the book in three sentences? Which concepts do you want to keep in mind or apply? How does the book relate to what you already know?”
  • I then publish my summaries on Goodreads or write an article about my favorite insights
  • How you can apply retrieval: You can come up with your own questions or use mine. If you don’t want to publish your summaries in public, you can write a summary into your journal, start a book club, create a private blog, or initiate a WhatsApp group for sharing book summaries.
  • a few days after we learn something, forgetting sets in
  • #3 Spaced Repetition
  • With spaced repetition, you repeat the same piece of information across increasing intervals.
  • The harder it feels to recall the information, the stronger the learning effect. “Spaced practice, which allows some forgetting to occur between sessions, strengthens both the learning and the cues and routes for fast retrieval,”
  • Why it works: It might sound counterintuitive, but forgetting is essential for learning. Spacing out practice might feel less productive than rereading a text because you’ll realize what you forgot. Your brain has to work harder to retrieve your knowledge, which is a good indicator of effective learning.
  • How I apply spaced repetition: After some weeks, I revisit a book and look at the summary questions (see #2). I try to come up with my answer before I look up my actual summary. I can often only remember a fraction of what I wrote and have to look at the rest.
  • “Knowledge trapped in books neatly stacked is meaningless and powerless until applied for the betterment of life.”
  • How you can apply spaced repetition: You can revisit your book summary medium of choice and test yourself on what you remember. What were your action points from the book? Have you applied them? If not, what hindered you?
  • By testing yourself in varying intervals on your book summaries, you’ll strengthen both learning and cues for fast retrieval.
  • Why interleaving works: Alternate working on different problems feels more difficult as it, again, facilitates forgetting.
  • How I apply interleaving: I read different books at the same time.
  • 1) Highlight everything you want to remember
  • #5 Self-Testing
  • While reading often falsely tricks us into perceived mastery, testing shows us whether we truly mastered the subject at hand. Self-testing helps you identify knowledge gaps and brings weak areas to the light
  • “It’s better to solve a problem than to memorize a solution.”
  • Why it works: Self-testing helps you overcome the illusion of knowledge. “One of the best habits a learner can instill in herself is regular self-quizzing to recalibrate her understanding of what she does and does not know.”
  • How I apply self-testing: I explain the key lessons from non-fiction books I want to remember to others. Thereby, I test whether I really got the concept. Often, I didn’t
  • instead of feeling frustrated, cognitive science made me realize that identifying knowledge gaps are a desirable and necessary effect for long-term remembering.
  • How you can apply self-testing: Teaching your lessons learned from a non-fiction book is a great way to test yourself. Before you explain a topic to somebody, you have to combine several mental tasks: filter relevant information, organize this information, and articulate it using your own vocabulary.
  • Now that I discovered how to use my Kindle as a learning device, I wouldn’t trade it for a paper book anymore. Here are the four steps it takes to enrich your e-reading experience
  • How you can apply interleaving: Your brain can handle reading different books simultaneously, and it’s effective to do so. You can start a new book before you finish the one you’re reading. Starting again into a topic you partly forgot feels difficult first, but as you know by now, that’s the effect you want to achieve.
  • it won’t surprise you that researchers proved highlighting to be ineffective. It’s passive and doesn’t create memory cues.
  • 2) Cut down your highlights in your browser
  • After you finished reading the book, you want to reduce your highlights to the essential part. Visit your Kindle Notes page to find a list of all your highlights. Using your desktop browser is faster and more convenient than editing your highlights on your e-reading device.
  • Now, browse through your highlights, delete what you no longer need, and add notes to the ones you really like. By adding notes to the highlights, you’ll connect the new information to your existing knowledge
  • 3) Use software to practice spaced repetitionThis part is the main reason for e-books beating printed books. While you can do all of the above with a little extra time on your physical books, there’s no way to systemize your repetition praxis.
  • Readwise is the best software to combine spaced repetition with your e-books. It’s an online service that connects to your Kindle account and imports all your Kindle highlights. Then, it creates flashcards of your highlights and allows you to export your highlights to your favorite note-taking app.
  • Common Learning Myths DebunkedWhile reading and studying evidence-based learning techniques I also came across some things I wrongly believed to be true.
  • #2 Effective learning should feel easyWe think learning works best when it feels productive. That’s why we continue to use ineffective techniques like rereading or highlighting. But learning works best when it feels hard, or as the authors of ‘Make It Stick’ write: “Learning that’s easy is like writing in sand, here today and gone tomorrow.”
  • In Conclusion
  • I developed and adjusted these strategies over two years, and they’re still a work in progress.
  • Try all of them but don’t force yourself through anything that doesn’t feel right for you. I encourage you to do your own research, add further techniques, and skip what doesn’t serve you
  • “In the case of good books, the point is not to see how many of them you can get through, but rather how many can get through to you.”— Mortimer J. Adler

Computers Already Learn From Us. But Can They Teach Themselves? - The New York Times - 0 views

  • We teach computers to see patterns, much as we teach children to read. But the future of A.I. depends on computer systems that learn on their own, without supervision, researchers say.
  • When a mother points to a dog and tells her baby, “Look at the doggy,” the child learns what to call the furry four-legged friends. That is supervised learning. But when that baby stands and stumbles, again and again, until she can walk, that is something else.Computers are the same.

Twitter aims to limit people sharing articles they have not read | Twitter | The Guardian - 1 views

False Assumption | SES - 0 views

  • In other words, this fallacy assumes that whatever it takes to make a premise true is already there, even if it is really absent or unknown.
  • This common fallacy of the false assumption often overlaps with a number of other logical fallacies in subtle ways, and thus it is not always obvious and can be difficult to spot. In fact, some logic texts consider false or unwarranted assumptions as an inherent characteristic of a whole host of other logical fallacies.¹ However there are characteristics of this fallacy which make it stand out—specifically the reliance of a premise on prior unsupported or unstated assumptions that turn out to be false
  • It’s simply part of human nature that we often tend to “fill in the blanks” and assume what isn’t there when limited information is given, and so we sometimes end up committing the fallacy without realizing it
  • ...4 more annotations...
  • First, be aware of your assumption
  • econd, check your assumptions
  • Third, remember that even if a premise is based on a false assumption, that does not necessarily mean that the premise itself is false
  • Finally, remember that the best arguments are usually those that identify and defend their own assumptions

    This article talks about false assumptions and jumping to conclusions which we talked a lot about in the beginning of TOK. It also addresses how to avoid the fallacy of false assumption which I think is something we did not talk as much about in class.

COVID-19 and Compassion Fatigue | Psychology Today - 0 views

  • “Researchers say our brains aren’t wired to make sense of big numbers.” A story about a single tragic death evokes waves of sadness and emotion in us. We focus on the individual’s details, their life story, and the circumstances of their death. As the number of victims increases, our ability to muster empathy fades, something often called compassion fatigue.
  • If we talk instead about multiple people like Constance Johnson at once or just give the numbers involved—about 4,200 women die every year from cervical cancer—the information loses its impact. We don’t comprehend a number like 4,200 the way we do the story of a single individual.
  • As the results of a study by Paul Slovic and colleagues in 2014 showed, the tendency to be charitable and feel compassion diminishes rapidly as the number of people involved increases from one.

  • After several puffs of neurotransmitter are released, however, that channel may undergo a process called “desensitization” in which it closes and stops responding to signals from the presynaptic neuron.
  • “Observing that the tendency to mentalize with one person more than many people is built into our brains does not mean we should accept it as an excuse for acting passively when facing large-scale crises. This observation implies, however, that we can no longer rely on our moral intuitions.”
  • eople may cope with the enormity of the pandemic by trying to find ways to minimize or even dismiss it. Saying that there are other diseases that cause more deaths than COVID-19 could be one such emotional mechanism.
  • We need to tell more stories about real people who have had COVID-19 and experienced it as more than mild symptoms, including stories about people who have been killed by the disease. The stories need to be told one by one. That way, we will be harnessing what we know from cognitive neuroscience to bring the sad message home.

You Are Already Living Inside a Computer - The Atlantic - 1 views

  • Nobody really needs smartphone-operated bike locks or propane tanks. And they certainly don’t need gadgets that are less trustworthy than the “dumb” ones they replace, a sin many smart devices commit. But people do seem to want them—and in increasing numbers.
  • Why? One answer is that consumers buy what is on offer, and manufacturers are eager to turn their dumb devices smart. Doing so allows them more revenue, more control, and more opportunity for planned obsolescence. It also creates a secondary market for data collected by means of these devices. Roomba, for example, hopes to deduce floor plans from the movement of its robotic home vacuums so that it can sell them as business intelligence.
  • And the more people love using computers for everything, the more life feels incomplete unless it takes place inside them.

  • Computers already are predominant, human life already takes place mostly within them, and people are satisfied with the results.
  • These devices pose numerous problems. Cost is one. Like a cheap propane gauge, a traditional bike lock is a commodity. It can be had for $10 to $15, a tenth of the price of Nokē’s connected version. Security and privacy are others. The CIA was rumored to have a back door into Samsung TVs for spying. Disturbed people have been caught speaking to children over hacked baby monitors. A botnet commandeered thousands of poorly secured internet-of-things devices to launch a massive distributed denial-of-service attack against the domain-name syste
  • Reliability plagues internet-connected gadgets, too. When the network is down, or the app’s service isn’t reachable, or some other software behavior gets in the way, the products often cease to function properly—or at all.
  • Turing guessed that machines would become most compelling when they became convincing companions, which is essentially what today’s smartphones (and smart toasters) do.
  • But Turing never claimed that machines could think, let alone that they might equal the human mind. Rather, he surmised that machines might be able to exhibit convincing behavior.
  • People choose computers as intermediaries for the sensual delight of using computers
  • ne such affection is the pleasure of connectivity. You don’t want to be offline. Why would you want your toaster or doorbell to suffer the same fate? Today, computational absorption is an ideal. The ultimate dream is to be online all the time, or at least connected to a computational machine of some kind.
  • Doorbells and cars and taxis hardly vanish in the process. Instead, they just get moved inside of computers.
  • “Being a computer” means something different today than in 1950, when Turing proposed the imitation game. Contra the technical prerequisites of artificial intelligence, acting like a computer often involves little more than moving bits of data around, or acting as a controller or actuator. Grill as computer, bike lock as computer, television as computer. An intermediary
  • Or consider doorbells once more. Forget Ring, the doorbell has already retired in favor of the computer. When my kids’ friends visit, they just text a request to come open the door. The doorbell has become computerized without even being connected to an app or to the internet. Call it “disruption” if you must, but doorbells and cars and taxis hardly vanish in the process. Instead, they just get moved inside of computers, where they can produce new affections.
  • The present status of intelligent machines is more powerful than any future robot apocalypse.
  • Why would anyone ever choose a solution that doesn’t involve computers, when computers are available? Propane tanks and bike locks are still edge cases, but ordinary digital services work similarly: The services people seek out are the ones that allow them to use computers to do things—from finding information to hailing a cab to ordering takeout. This is a feat of aesthetics as much as it is one of business. People choose computers as intermediaries for the sensual delight of using computers, not just as practical, efficient means for solving problems.
  • This is not where anyone thought computing would end up. Early dystopic scenarios cautioned that the computer could become a bureaucrat or a fascist, reducing human behavior to the predetermined capacities of a dumb machine. Or else, that obsessive computer use would be deadening, sucking humans into narcotic detachment.Those fears persist to some extent, partly because they have been somewhat realized. But they have also been inverted. Being away from them now feels deadening, rather than being attached to them without end. And thus, the actions computers take become self-referential: to turn more and more things into computers to prolong that connection.
  • But the real present status of intelligent machines is both humdrum and more powerful than any future robot apocalypse. Turing is often called the father of AI, but he only implied that machines might become compelling enough to inspire interaction. That hardly counts as intelligence, artificial or real. It’s also far easier to achieve. Computers already have persuaded people to move their lives inside of them. The machines didn’t need to make people immortal, or promise to serve their every whim, or to threaten to destroy them absent assent. They just needed to become a sufficient part of everything human beings do such that they can’t—or won’t—imagine doing those things without them.
  • . The real threat of computers isn’t that they might overtake and destroy humanity with their future power and intelligence. It’s that they might remain just as ordinary and impotent as they are today, and yet overtake us anyway.

Ahimsa Online - The Message - Medium - 0 views

  • I stopped getting in fights on the net, and tried to practice gentleness and kindness with people I found here. I didn’t defend myself, rally the troops, or pick sides. Instead, in the ever-growing Mexican stand-off of social media, I decided to put my gun down first.
  • It was not an easy thing to give up the idea of winning the fights, especially online. I am naturally good with words, and I’ve known it since I was young. I have felt strong winning an argument, slamming people, sometimes watching them log off, in shame. I have slam dunked the response, and crushed egos under well-timed insults. But that strength was always so precarious by comparison to a practice of gentleness — what if they won the fight next time? What if I wasn’t fast enough, and I ended with the onlookers jeering me, telling me I should go kill myself instead of my particular bad guy? Sometimes I fought with people for a show, so that onlookers wouldn’t make the same mistake my opponents did. But in my year of Ahimsa, I found that the performative gentleness was, like the gentle mind, much more powerful.

For people used to power, speaking on the net gives them a granularity in their speech without precedent. It empowers them to speak in ever more sophisticated and persuasive ways.
  • I found myself on Twitter one night speaking to men’s rights advocates about sexual consent. I tried my gentleness, I tried to explain my concerns, my doubts, the outcomes I feared when people weren’t able to give sober and informed consent. I never got angry, but also tried to understand their fears. Eventually it resolved into a productive conversation. They were always hesitant, but they couldn’t seem to stay mad at me. I came to understand more about how men come to that position, and how to meet them where they are. Undoubtedly it won’t always work, but for those who only want to scream and never to talk, I can at least now see the depth of their fear and feel compassion for them.
  • One day I spoke with a man who hated the idea that he might have white privilege. I tried to explain gently what it meant, but he could only see his own suffering and misfortune, and those without his privilege doing better than him. I talked to him more about his story, looking for a place to explain in terms he would understand what this thing was, and why it was there even if he didn’t see it as benefitting him. Eventually he pulled his trump card: his life was so bad he was suicidal. The only reason he hadn’t killed himself, he told me, was that he didn’t have the courage. I realized this wasn’t a political conversation at all, this was a soul in pain, crying for help.
  • Beyond the text and pictures we see before us is the skin, and beneath, the blood and viscera, all the way to the cavern of the brain, the mind made of time and memories. We are, every one of us, creatures of need and connection, not merely eschewing disconnection but beings literally incapable of unconnected life.

Elephant Seal Facts (Genus Mirounga) - 0 views

  • The elephant seal (genus Mirounga) is the world's largest seal. There are two species of elephant seals, named according to the hemisphere in which they are found. Northern elephant seals (M. angustirostris) are found in coastal waters around Canada and Mexico, while southern elephant seals (M. leonina) are found off the coast of New Zealand, South Africa, and Argentina.
  • At sea, elephant seals range solo. They return to established breeding colonies each winter. Females become mature around 3 to 6 years of age, while males mature at 5 to 6 years.However, males need to achieve alpha status to mate, which is normally between the ages of 9 and 12. Males battle each other using body weight and teeth. While deaths are rare, scarring is common. An alpha male's harem ranges from 30 to 100 females. Other males wait on the edges of the colony, sometimes mating with females before the alpha male chases them away. Males remain on land over the winter to defend territory, meaning they don't leave to hunt.
  • Elephant seals have been hunted for their meat, fur, and blubber. Both northern and southern elephant seals were hunted to the brink of extinction. By 1892, most people believed the northern seals to be extinct. But in 1910, a single breeding colony was found around Guadalupe Island off Mexico's Baja California coast. At the end of the 19th century, new marine conservation legislation was put in place to protect the

Huge MIT Study of 'Fake News': Falsehoods Win on Twitter - The Atlantic - 0 views

  • “Falsehood flies, and the Truth comes limping after it,” Jonathan Swift once wrote.It was hyperbole three centuries ago. But it is a factual description of social media, according to an ambitious and first-of-its-kind study published Thursday in Science.
  • By every common metric, falsehood consistently dominates the truth on Twitter, the study finds: Fake news and false rumors reach more people, penetrate deeper into the social network, and spread much faster than accurate stories.
  • “It seems to be pretty clear [from our study] that false information outperforms true information,” said Soroush Vosoughi, a data scientist at MIT who has studied fake news since 2013 and who led this study. “And that is not just because of bots. It might have something to do with human nature.”

  • A false story is much more likely to go viral than a real story, the authors find. A false story reaches 1,500 people six times quicker, on average, than a true story does.
  • “In short, I don’t think there’s any reason to doubt the study’s results,” said Rebekah Tromble, a professor of political science at Leiden University in the Netherlands, in an email.
  • It’s a question that can have life-or-death consequences.“[Fake news] has become a white-hot political and, really, cultural topic, but the trigger for us was personal events that hit Boston five years ago,” said Deb Roy, a media scientist at MIT and one of the authors of the new study.
  • Ultimately, they found about 126,000 tweets, which, together, had been retweeted more than 4.5 million times. Some linked to “fake” stories hosted on other websites. Some started rumors themselves, either in the text of a tweet or in an attached image. (The team used a special program that could search for words contained within static tweet images.) And some contained true information or linked to it elsewhere.
  • Tweet A and Tweet B both have the same size audience, but Tweet B has more “depth,” to use Vosoughi’s term. It chained together retweets, going viral in a way that Tweet A never did. “It could reach 1,000 retweets, but it has a very different shape,” he said.Here’s the thing: Fake news dominates according to both metrics. It consistently reaches a larger audience, and it tunnels much deeper into social networks than real news does. The authors found that accurate news wasn’t able to chain together more than 10 retweets. Fake news could put together a retweet chain 19 links long—and do it 10 times as fast as accurate news put together its measly 10 retweets.
  • What does this look like in real life? Take two examples from the last presidential election. In August 2015, a rumor circulated on social media that Donald Trump had let a sick child use his plane to get urgent medical care. Snopes confirmed almost all of the tale as true. But according to the team’s estimates, only about 1,300 people shared or retweeted the story.
  • Why does falsehood do so well? The MIT team settled on two hypotheses.First, fake news seems to be more “novel” than real news. Falsehoods are often notably different from the all the tweets that have appeared in a user’s timeline 60 days prior to their retweeting them, the team found.Second, fake news evokes much more emotion than the average tweet. The researchers created a database of the words that Twitter users used to reply to the 126,000 contested tweets, then analyzed it with a state-of-the-art sentiment-analysis tool. Fake tweets tended to elicit words associated with surprise and disgust, while accurate tweets summoned words associated with sadness and trust, they found.
  • It suggests—to me, at least, a Twitter user since 2007, and someone who got his start in journalism because of the social network—that social-media platforms do not encourage the kind of behavior that anchors a democratic government. On platforms where every user is at once a reader, a writer, and a publisher, falsehoods are too seductive not to succeed: The thrill of novelty is too alluring, the titillation of disgust too difficult to transcend. After a long and aggravating day, even the most staid user might find themselves lunging for the politically advantageous rumor. Amid an anxious election season, even the most public-minded user might subvert their higher interest to win an argument.

Computers Are Learning to Read-But They're Still Not So Smart | WIRED - 0 views

  • computers still weren’t very good at understanding the written word. Sure, they had become decent at simulating that understanding in certain narrow domains, like automatic translation or sentiment analysis (for example, determining if a sentence sounds “mean or nice,” he said). But Bowman wanted measurable evidence of the genuine article: bona fide, human-style reading comprehension in English. So he came up with a test
  • The machines bombed. Even state-of-the-art neural networks scored no higher than 69 out of 100 across all nine tasks: a D-plus, in letter grade terms. Bowman and his coauthors weren’t surprised. Neural networks — layers of computational connections built in a crude approximation of how neurons communicate within mammalian brains
  • It produced a GLUE score of 80.5. On this brand-new benchmark designed to measure machines’ real understanding of natural language — or to expose their lack thereof — the machines had jumped from a D-plus to a B-minus in just six months.

  • The only problem is that perfect rulebooks don’t exist, because natural language is far too complex and haphazard to be reduced to a rigid set of specifications.
  • Researchers simply fed their neural networks massive amounts of written text copied from freely available sources like Wikipedia — billions of words, preformatted into grammatically correct sentences — and let the networks derive next-word predictions on their own. In essence, it was like asking the person inside a Chinese room to write all his own rules, using only the incoming Chinese messages for reference.“The great thing about this approach is it turns out that the model learns a ton of stuff about syntax,”
  • The nonsequential nature of the transformer represented sentences in a more expressive form, which Uszkoreit calls treelike. Each layer of the neural network makes multiple, parallel connections between certain words while ignoring others — akin to a student diagramming a sentence in elementary school. These connections are often drawn between words that may not actually sit next to each other in the sentence. “Those structures effectively look like a number of trees that are overlaid,” Uszkoreit explained.
  • But instead of concluding that BERT could apparently imbue neural networks with near-Aristotelian reasoning skills, they suspected a simpler explanation: that BERT was picking up on superficial patterns in the way the warrants were phrased.

Why Donald Trump can't grasp this moment (Opinion) - CNN - 0 views

  • By 1989, when he spoke out about the infamous assault on a jogger in Central Park he would decry "the complete breakdown" of society and yearn for the days "when I was young" and he saw cops rough-up two loudmouths who had harassed a waitress. He wanted a return of that sort of policing and called on New York State to adopt the death penalty after the arrests of the five young black and Latino men in the jogger case. Years later, those men were found to be innocent.
  • Trump didn't seem to consider the suffering that caused the crises of his youth.

  • His drive for the presidency ended with him in the Oval Office thanks to an Electoral College system that lets the loser of the national vote gain the presidency.
  • When asked about when America was great he recalled the time of his childhood, the 1940s and 1950s, when "we were not pushed around, we were respected by everybody, we had just won a war, we were pretty much doing what we had to do." He also remains nostalgic for the stereotypical 1950s housewife, speaking wistfully of women like actress Donna Reed, who always seemed to play the role of a gentle and accommodating woman.
  • With no experience in government, the military, or genuine civic engagement, Trump brought his true self to the White House, where his team included many who seemed to share his back-to-the-50s mentality. At the Justice Department federal efforts to safeguard civil rights were curbed. The Department of Education rolled back protections for the rights of women and minorities. The Pentagon barred transgender recruits.

Shaking Off Outmoded Ideas On Race | Duke Today - 0 views

Can Brain Science Help Us Break Bad Habits? | The New Yorker - 0 views

  • Texts arrived with the tones of a French horn and were similarly dispatched. Soon, I was reaching for the device every time it made a sound, like Pavlov’s dog salivating when it heard a bell. This started to interfere with work and conversations. The machine had seemed like a miraculous servant, but gradually I became its slave.
  • Habits, good and bad, have long fascinated philosophers and policymakers. Aristotle, in the Nicomachean Ethics, surveyed existing notions of virtue and offered this summary: “Some thinkers hold that it is by nature that people become good, others that it is by habit, and others that it is by instruction.” He concluded that habits were responsible. Cicero called habit “second nature,” a phrase that we still use.
  • Our minds, Wood explains, have “multiple separate but interconnected mechanisms that guide behavior.” But we are aware only of our decision-making ability—a phenomenon known as the “introspection illusion”—and that may be why we overestimate its power.

  • n Mischel’s marshmallow experiment, only a quarter of the subjects were able to resist eating the marshmallow for fifteen minutes. This implies that a large majority of us lack the self-control required to succeed in life.
  • They were most successful at adopting productive behaviors not when they resolved to do better, or distracted themselves from temptation, but when they altered their environment. Instead of studying on a couch in a dorm, with a TV close by, they went to the library. They ate better when they removed junk food from the dorm refrigerator. “Successful self-control,” Wood writes, “came from essentially covering up the marshmallow.”
  • Both, too, emphasize the role of conscious effort—not in resisting habit but in analyzing it, the better to formulate a strategy for reform.
  • Wood advises us to come up with new rewards as substitutes for the ones the phone provided. I listened to music on the car radio. In the evening, instead of scrolling through tweets and e-mails, I sought out authors I’d never read. At the end of each day, I felt calmer, and free.

The Language You Speak Influences Where Your Attention Goes - Scientific American Blog Network - 0 views

  • Research with speakers of different languages revealed that bilingual speakers not only look at words that share sounds in one language but also at words that share sounds across their two languages. When Russian-English bilinguals hear the English word marker, they also look at a stamp, because the Russian word for stamp is marka.
  • Even more stunning, speakers of different languages differ in their patterns of eye movements when no language is used at all. In a simple visual search task in which people had to find a previously seen object among other objects, their eyes moved differently depending on what languages they knew. For example, when looking for a clock, English speakers also looked at a cloud. Spanish speakers, on the other hand, when looking for the same clock, looked at a present, because the Spanish names for clock and present—reloj and regalo—overlap at their onset.
  • Because of the way our brain organizes and processess linguistic and nonlinguistic information, a single word can set off a domino effect that cascades throughout the cognitive system.

  • Not only is the language system thoroughly interactive with a high degree of co-activation across words and concepts, but it also impacts our processing in other domains such as vision, attention and cognitive control.
  • In other words, it is safe to say that the language you speak influences how you see the world not only figuratively but also quite literally, down to the mechanics of your eye movements.

Baidu has a new trick for teaching AI the meaning of language - MIT Technology Review - 0 views

  • Earlier this month, a Chinese tech giant quietly dethroned Microsoft and Google in an ongoing competition in AI. The company was Baidu, China’s closest equivalent to Google, and the competition was the General Language Understanding Evaluation, otherwise known as GLUE.
  • GLUE is a widely accepted benchmark for how well an AI system understands human language. It consists of nine different tests for things like picking out the names of people and organizations in a sentence and figuring out what a pronoun like “it” refers to when there are multiple potential antecedents. A language model that scores highly on GLUE, therefore, can handle diverse reading comprehension tasks. Out of a full score of 100, the average person scores around 87 points. Baidu is now the first team to surpass 90 with its model, ERNIE.
  • BERT, by contrast, considers the context before and after a word all at once, making it bidirectional. It does this using a technique known as “masking.” In a given passage of text, BERT randomly hides 15% of the words and then tries to predict them from the remaining ones. This allows it to make more accurate predictions because it has twice as many cues to work from.

  • When Baidu researchers began developing their own language model, they wanted to build on the masking technique. But they realized they needed to tweak it to accommodate the Chinese language.In English, the word serves as the semantic unit—meaning a word pulled completely out of context still contains meaning. The same cannot be said for characters in Chinese.
  • It considers the ordering of sentences and the distances between them, for example, to understand the logical progression of a paragraph. Most important, however, it uses a method called continuous training that allows it to train on new data and new tasks without it forgetting those it learned before. This allows it to get better and better at performing a broad range of tasks over time with minimal human interference.
  • “When we first started this work, we were thinking specifically about certain characteristics of the Chinese language,” says Hao Tian, the chief architect of Baidu Research. “But we quickly discovered that it was applicable beyond that.”
