  • From the self-absorbed faux seriousness of some (meditating on the grounds of Auschwitz-Birkenau!) to the jarring jokiness of others (hitching a ride by the train tracks!), the pictures have fed a perception of today’s youth as a bunch of technology-obsessed, self-indulgent narcissists. They also bring to mind the photos compiled in the popular Selfies at Funerals Tumblr blog. But if the “funeral selfie” kids were somehow hilarious in their inappropriateness, there’s nothing quite like seeing Israeli teens blowing kisses from the death camps of Poland to send you into a confusing and curious rage.

  • How large is Africa compared to the United States, or Western Europe? Most inhabitants of the latter places might guess it is a little larger, but few would have any idea of the scale of the difference. This has led German graphics designer Kai Krause to produce this map to shake people's perceptions a little.
  • Any attempt to map a spherical planet onto a flat map will involve distortions of size, shape or both. There is a passionate debate among cartographers about the best way to hang the world on a wall, but most agree that the most common maps we get our sense of the world from are very bad ways to do it. The problem is that these maps exaggerate the size of the countries at high  latitudes, and shrink places near the equator - leading to a perception that Europe is larger than South America, to pick just one example among many.
  • Africa, which spans the equator, fares particularly badly on these sorts of projections: Krause says, "Africa is so mind-numbingly immense, that it exceeds the common assumptions by just about anyone I ever met: it contains the entirety of the USA, all of China, India, as well as Japan and pretty much all of Europe as well - all combined!”  Some have argued that since people associate size with importance this encourages the already strong tendency of the world's wealthiest nations to disregard those who live in the tropics.

    "Science is unabashedly radical, willing to toss aside established wisdom and ideas to embrace mind-warping new concepts (if the data backs them up). Science is relentlessly conservative, deeply suspicious of new claims and determined to hold firm to cherished truths that have stood the test of time. As strange as it may seem, both these contradictory statements have held true throughout the 450-year history of "modern" science. In fact, they are what have given science the stability and creativity that root its cultural power."

  • There’s no Rosetta Stone for scientific translation. It’s quite simple really. The first step is getting rid of the technical language.
  • This sounds like a straightforward instruction, but many enormously intelligent people fail to follow it. The trick they fail to master is to train their brains to think in two ways. One, like a scientist; and two, like someone with no scientific training whatsoever.
  • And whenever I see or hear journalists or politicians discussing a particularly important social science – economics – I just don’t see them making the same efforts of jargon removal and technical translation. Whether it’s discussion of debt, or the argument for austerity, it’s hard to find good economics communication, where the language is rinsed free of jargon.

  • Not even he believes that the various flaws that bedevil decision-making can be successfully corrected. The most damaging of these is overconfidence: the kind of optimism that leads governments to believe that wars are quickly winnable and capital projects will come in on budget despite statistics predicting exactly the opposite. It is the bias he says he would most like to eliminate if he had a magic wand. But it “is built so deeply into the structure of the mind that you couldn’t change it without changing many other things”.

  • David McRaney explores the sunk cost fallacy, a strangely twisted bit of logic that seems to pop into the human mind once a person has experienced the pain of loss or the ickiness of waste on his or her way toward a concrete goal. It’s illogical, irrational, unreasonable - and as a perfectly normal human being, you act under its influence all the time.

  • Michel and his co-authors put their magic tongue to use in a simple but provocative experiment, carried out late last year and described in the current issue of the scientific journal Perception. Although the involvement of a stretchy pink latex tongue makes it easy to mistake the experiment for a cheap gag, it’s actually an important addition to a distinguished tradition of psychological research that studies illusions for what they can reveal about how the brain constructs reality.
  • “A lot of my colleagues don’t want to think about the mouth and flavor,” he said. “They all want to study hearing and vision.” Spence’s work, by contrast, is concerned with how the brain combines input from multiple senses to create perception, and he regularly finds himself arguing for the importance of touch, taste, and smell in the construction of our day-to-day experiences. And, while the hand is limited to two senses, the tongue offers the possibility of testing four sensory modes: touch, sight, taste, and smell (through a process called retronasal olfaction).

Why Ants Handle Traffic Better Than You Do : NPR - 0 views

shared by Lawrence Hrubes on 19 Jan 15 - No Cached
  • Could studying ants reveal clues to reducing highway traffic jams? Physicist Apoorva Nagar at the Indian Institute of Space Science and Technology thinks the answer is yes. Nagar says he got interested in the topic when he came across a study by German and Indian researchers showing that ants running along a path were able to maintain a steady speed even when there were a large number of ants on the path. Nagar says there are three main reasons ants don't jam up. Number one, ants don't have egos. They don't show off by zooming past people. "The second thing is, they do not mind a few accidents, or collisions," say Nagar. So unless there's a serious pileup, they just keep going.
  • The third reason, he says, is that ants seem to get more disciplined when paths get crowded, running in straighter lines, and varying their speed less. They're less likely to make unexpected moves in this sort of heavy traffic. It's the kind of steady control you see when a computer is controlling a car rather than a human. There's less variability unless it's absolutely called for. Nagar felt this kind of behavior could be explained by something called the Langevin equation, an equation physicists use when describing the movement of liquids, or how individual atoms behave in a lattice.

Is Bilingualism Really an Advantage? - The New Yorker - 1 views

www.newyorker.com/...ilingual-advantage-aging-brain

TOK language human sciences social studies bias

shared by Lawrence Hrubes on 26 Jan 15 - No Cached
  • Many modern language researchers agree with that premise. Not only does speaking multiple languages help us to communicate but bilingualism (or multilingualism) may actually confer distinct advantages to the developing brain. Because a bilingual child switches between languages, the theory goes, she develops enhanced executive control, or the ability to effectively manage what are called higher cognitive processes, such as problem-solving, memory, and thought. She becomes better able to inhibit some responses, promote others, and generally emerges with a more flexible and agile mind. It’s a phenomenon that researchers call the bilingual advantage.
  • For the first half of the twentieth century, researchers actually thought that bilingualism put a child at a disadvantage, something that hurt her I.Q. and verbal development. But, in recent years, the notion of a bilingual advantage has emerged from research to the contrary, research that has seemed both far-reaching and compelling, much of it coming from the careful work of the psychologist Ellen Bialystok. For many tasks, including ones that involve working memory, bilingual speakers seem to have an edge. In a 2012 review of the evidence, Bialystok showed that bilinguals did indeed show enhanced executive control, a quality that has been linked, among other things, to better academic performance. And when it comes to qualities like sustained attention and switching between tasks effectively, bilinguals often come out ahead. It seems fairly evident then that, given a choice, you should raise your child to speak more than one language.
  • Systematically, de Bruin combed through conference abstracts from a hundred and sixty-nine conferences, between 1999 and 2012, that had to do with bilingualism and executive control. The rationale was straightforward: conferences are places where people present in-progress research. They report on studies that they are running, initial results, initial thoughts. If there were a systematic bias in the field against reporting negative results—that is, results that show no effects of bilingualism—then there should be many more findings of that sort presented at conferences than actually become published. That’s precisely what de Bruin found. At conferences, about half the presented results provided either complete or partial support for the bilingual advantage on certain tasks, while half provided partial or complete refutation. When it came to the publications that appeared after the preliminary presentation, though, the split was decidedly different. Sixty-eight per cent of the studies that demonstrated a bilingual advantage found a home in a scientific journal, compared to just twenty-nine per cent of those that found either no difference or a monolingual edge. “Our overview,” de Bruin concluded, “shows that there is a distorted image of the actual study outcomes on bilingualism, with researchers (and media) believing that the positive effect of bilingualism on nonlinguistic cognitive processes is strong and unchallenged.”

language culture swearing

shared by Lawrence Hrubes on 07 Mar 15 - No Cached
  • We tend to think of swear words as one entity, but they actually serve several distinct functions. Steven Pinker, in The Stuff of Thought, lists five different ways we can swear: “descriptively (Let’s fuck), idiomatically (It’s fucked up), abusively (Fuck you…!), emphatically (This is fucking amazing), and cathartically (Fuck!!!).” None of these functions require swearwords. In Bikol (a language of the Philippines), there’s a special anger vocabulary – many words have alternative words that refer to just the same thing but also mean you’re angry. In Luganda (an African language), you can make a word insulting just by changing its noun class prefix – from a class for persons to a class for certain kinds of objects, for instance. In Japanese, you can insult someone badly just by using an inappropriate form of ‘you’.

  • Entertaining the idea of a peculiar long number such as pi puts me in mind of its cousins twice removed, prime numbers, which have so many strange properties. Prime numbers are those numbers, such as 3, 5, 7, 11, and so on, that can be cleanly divided only by one and themselves. Primes and pi suggest a benign infinity, a pleasing order—pi because of its endlessness and its relation to the circle, and primes because no matter how far you travel on the number line you will always encounter a prime, as Euclid proved in 300 B.C. Recently, Yitang Zhang solved a problem involving prime numbers called bounded gaps that had been open for more than a hundred years. Zhang proved that no matter how far you go on the number line, even to the range where the numbers would fill many books, there will, on an infinite number of occasions, be two prime numbers within seventy million places of each other. (Other mathematicians have reduced this gap to two hundred and forty six.) Before, it had not been known whether any such range applied to prime numbers, which seem to behave, especially as they get larger, as if they appear at random.
  • Number theory is a discipline done for no purpose. It is practiced by people who believe that numbers have properties that exemplify an orderliness and beauty in the universe. The story of numbers is a story of creation not directly contained in the Scriptures, but if a divinity didn’t create numbers and their properties, what accounts for them? The necessity of counting doesn’t entirely explain pi or primes. A breakthrough in number theory is called a discovery, not an invention. There isn’t yet any explanation for the properties of pi or for primes. There is only the sense of wonder that the world contains such extravagant mysteries so close at hand.

  • AMERICANS and Europeans stand out from the rest of the world for our sense of ourselves as individuals. We like to think of ourselves as unique, autonomous, self-motivated, self-made. As the anthropologist Clifford Geertz observed, this is a peculiar idea.People in the rest of the world are more likely to understand themselves as interwoven with other people — as interdependent, not independent. In such social worlds, your goal is to fit in and adjust yourself to others, not to stand out. People imagine themselves as part of a larger whole — threads in a web, not lone horsemen on the frontier. In America, we say that the squeaky wheel gets the grease. In Japan, people say that the nail that stands up gets hammered down.
  • These are broad brush strokes, but the research demonstrating the differences is remarkably robust and it shows that they have far-reaching consequences. The social psychologist Richard E. Nisbett and his colleagues found that these different orientations toward independence and interdependence affected cognitive processing. For example, Americans are more likely to ignore the context, and Asians to attend to it. Show an image of a large fish swimming among other fish and seaweed fronds, and the Americans will remember the single central fish first. That’s what sticks in their minds. Japanese viewers will begin their recall with the background. They’ll also remember more about the seaweed and other objects in the scene.Another social psychologist, Hazel Rose Markus, asked people arriving at San Francisco International Airport to fill out a survey and offered them a handful of pens to use, for example four orange and one green; those of European descent more often chose the one pen that stood out, while the Asians chose the one more like the others.
  • In May, the journal Science published a study, led by a young University of Virginia psychologist, Thomas Talhelm, that ascribed these different orientations to the social worlds created by wheat farming and rice farming. Rice is a finicky crop. Because rice paddies need standing water, they require complex irrigation systems that have to be built and drained each year. One farmer’s water use affects his neighbor’s yield. A community of rice farmers needs to work together in tightly integrated ways. Not wheat farmers. Wheat needs only rainfall, not irrigation. To plant and harvest it takes half as much work as rice does, and substantially less coordination and cooperation. And historically, Europeans have been wheat farmers and Asians have grown rice.Continue reading the main story Continue reading the main story Continue reading the main story The authors of the study in Science argue that over thousands of years, rice- and wheat-growing societies developed distinctive cultures: “You do not need to farm rice yourself to inherit rice culture.”

  • Mischel’s story isn’t surprising—nicotine is addictive, and quitting is difficult—except for one thing: Mischel is the creator of the marshmallow test, one of the most famous experiments in the history of psychology, which is often cited as evidence of the importance of self-control. In the original test, which was administered at the Bing Nursery School, at Stanford, in the nineteen-sixties, Mischel’s team would present a child with a treat (marshmallows were just one option) and tell her that she could either eat the one treat immediately or wait alone in the room for several minutes until the researcher returned, at which point she could have two treats. The promised treats were always visible and the child knew that all she had to do to stop the agonizing wait was ring a bell to call the experimenter back—although in that case, she wouldn’t get the second treat. The longer a child delayed gratification, Mischel found—that is, the longer she was able to wait—the better she would fare later in life at numerous measures of what we now call executive function. She would perform better academically, earn more money, and be healthier and happier. She would also be more likely to avoid a number of negative outcomes, including jail time, obesity, and drug use.
  • It was not until one day in the late nineteen-sixties, when he saw a man with metastasized lung cancer in the halls of Stanford’s medical school—chest exposed, head shaved, little green “x” marks all over his body, marking the points where radiation would go—that Mischel realized he was fooling himself. Finally, something clicked. From then on, each time he wanted a cigarette (approximately every three minutes, by his count) he would create a picture in his mind of the man in the hallway. As he described it to me, “I changed the objective value of the cigarette. It went from something I craved to something disgusting.” He hasn’t had a smoke since.
  • Lawrence Hrubes on 14 Feb 15
     
    "Mischel, who is now eighty-four years old, has just published his first popular book, "The Marshmallow Test: Mastering Self-Control." It is part memoir, part scientific analysis, and part self-help guide. In the book, he describes the original impetus for the marshmallow study. At the time, his daughters, Judith, Rebecca, and Linda, were three, four, and five years old, respectively. "I began to see this fascinating phenomenon where they morphed from being highly impulsive, immediate creatures who couldn't delay anything," he told me. "There were these amazingly rapid changes-everything around them was the same, but something inside them had changed. I realized I didn't have a clue what was going on in their heads." He wondered what was it that had enabled them to go from deciding that they wanted to wait to actually being able to do so. He found the answer among their classmates at the Bing preschool."

  • "A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point."
  • The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself. We apply fight-or-flight reflexes not only to predators, but to data itself. We're not driven only by emotions, of course—we also reason, deliberate. But reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about.
  • In other words, when we think we're reasoning, we may instead be rationalizing. Or to use an analogy offered by University of Virginia psychologist Jonathan Haidt: We may think we're being scientists, but we're actually being lawyers
  • ...2 more annotations...
  • A key question—and one that's difficult to answer—is how "irrational" all this is. On the one hand, it doesn't make sense to discard an entire belief system, built up over a lifetime, because of some new snippet of information.
  • Okay, so people gravitate toward information that confirms what they believe, and they select sources that deliver it. Same as it ever was, right? Maybe, but the problem is arguably growing more acute, given the way we now consume information—through the Facebook links of friends, or tweets that lack nuance or context, or "narrowcast" and often highly ideological media that have relatively small, like-minded audiences. Those basic human survival skills of ours, says Michigan's Arthur Lupia, are "not well-adapted to our information age."
