This is your brain on knockoffs: The science of how we trick ourselves into not believi... - 0 views

  • In 2011, Martin Kemp, an Oxford art history professor, ran an experiment referenced in Ragai’s book, in which 14 non-specialists were shown genuine and fake “Rembrandt” paintings while undergoing brain scans. A painting was shown to them and they were told it was by Rembrandt. Another painting was shown to them and they were told it was a fake. By measuring the pleasure centers of the brain, Kemp concluded that “the way we view art is not rational.” Being told a work was authentic (whether or not it actually was) activated pleasure centers when it was shown, which was not the case when the viewer was told it was inauthentic (even if it was actually the real deal). It’s all about anticipation. If you’re poured a glass of wine and told it’s a 1955 Chateau Lafite Rothschild, you’ll enjoy it much more than if you’re told it’s a 2015 Trader Joe’s wine-in-a-box, whichever it truly happens to be. (For more on this, see my eBook single on wine forgery).
  • But while non-experts are led by being told what is authentic and what is not, clever forgers do a more elaborate version of the same thing to snare specialists. Rather than telling them “this is authentic,” which would summon a defensive reaction on the part of the expert (“Oh yeah, I’m the expert here, I’ll tell you what’s authentic and what isn’t”), they lay a trail of traps by scattering subtle clues that lead the expert into following a carefully plotted trail, but to come to their own conclusion about the authenticity of the work in question.

Martha, My Dear: What De-Extinction Can't Bring Back : The New Yorker - 0 views

  • There are a lots of potential problems with de-extinction, starting with the fact that, in any rigorous way, it’s probably impossible. Recent advances in paleogenetics have made it feasible to reassemble the genomes of recently extinct animals, like the passenger pigeon and even the mammoth. But the results are inexact—there will always be uncertainties. And even then things get really tricky.
  • The nearest living relative of the passenger pigeon is a bird called the band-tailed pigeon, which lives in the western United States and in Canada. The theory behind Revive & Restore’s resurrection effort—which, it should be noted, has a staff of one—is that, with some very sophisticated genetic slicing and dicing, a band-tailed pigeon embryo could be converted into a passenger pigeon embryo. This embryo could then be transferred to a band-tailed pigeon egg and raised by band-tailed pigeon parents.

How politics makes us stupid - Vox - 0 views

  • In April and May of 2013, Yale Law professor Dan Kahan — working with coauthors Ellen Peters, Erica Cantrell Dawson, and Paul Slovic — set out to test a question that continuously puzzles scientists: why isn’t good evidence more effective in resolving political debates? For instance, why doesn’t the mounting proof that climate change is a real threat persuade more skeptics?
  • The leading theory, Kahan and his coauthors wrote, is the Science Comprehension Thesis, which says the problem is that the public doesn’t know enough about science to judge the debate. It’s a version of the More Information Hypothesis: a smarter, better educated citizenry wouldn’t have all these problems reading the science and accepting its clear conclusion on climate change. But Kahan and his team had an alternative hypothesis. Perhaps people aren’t held back by a lack of knowledge. After all, they don’t typically doubt the findings of oceanographers or the existence of other galaxies. Perhaps there are some kinds of debates where people don’t want to find the right answer so much as they want to win the argument. Perhaps humans reason for purposes other than finding the truth — purposes like increasing their standing in their community, or ensuring they don’t piss off the leaders of their tribe. If this hypothesis proved true, then a smarter, better-educated citizenry wouldn’t put an end to these disagreements. It would just mean the participants are better equipped to argue for their own side.
  • Kahan doesn’t find it strange that we react to threatening information by mobilizing our intellectual artillery to destroy it. He thinks it’s strange that we would expect rational people to do anything else.

  • Kahan’s studies, depressing as they are, are also the source of his optimism: he thinks that if researchers can just develop a more evidence-based model of how people treat questions of science as questions of identity then scientists could craft a communications strategy that would avoid those pitfalls. "My hypothesis is we can use reason to identify the sources of the threats to our reason and then we can use our reason to devise methods to manage and control those processes," he says.

Jaron Lanier on Lack of Transparency in Facebook Study - NYTimes.com - 0 views

  • SHOULD we worry that technology companies can secretly influence our emotions? Apparently so.
  • Research with human subjects is generally governed by strict ethical standards, including the informed consent of the people who are studied. Facebook’s generic click-through agreement, which almost no one reads and which doesn’t mention this kind of experimentation, was the only form of consent cited in the paper. The subjects in the study still, to this day, have not been informed that they were in the study. If there had been federal funding, such a complacent notion of informed consent would probably have been considered a crime. Subjects would most likely have been screened so that those at special risk would be excluded or handled with extra care.
  • It is unimaginable that a pharmaceutical firm would be allowed to randomly, secretly sneak an experimental drug, no matter how mild, into the drinks of hundreds of thousands of people, just to see what happens, without ever telling those people. Imagine a pharmaceutical researcher saying, “I was only looking at a narrow research question, so I don’t know if my drug harmed anyone, and I haven’t bothered to find out.” Unfortunately, this seems to be an acceptable attitude when it comes to experimenting with people over social networks. It needs to change.

  • Stealth emotional manipulation could be channeled to sell things (you suddenly find that you feel better after buying from a particular store, for instance), but it might also be used to exert influence in a multitude of other ways.

Do You Believe In Magic? Interview with Dr. Paul Offit - CSI - 0 views

  • I think there is something to be said for the placebo response, which is unfortunately named. I think when people hear the word “placebo,” they assume that it's dismissive, trivializing, that it's just all in my head and that it's not real. I think that in fact, the placebo response can be a physiological response. I think believing that you are about to be helped in some way goes a long way to being helped in some way.
  • If you believe that human anatomy has nothing to do with rivers in China or days of the year, then there's nothing accurate about acupuncture. Indeed, if you look at people who benefit from acupuncture, it doesn't matter where you put the needles. In fact, it doesn't even matter whether you put the needles under the skin! Even these retractable needles seem to work, so‑called “acupressure.” That is interesting!

BBC - Future - The surprising downsides of being clever - 1 views

  • The first steps to answering these questions were taken almost a century ago, at the height of the American Jazz Age. At the time, the new-fangled IQ test was gaining traction, after proving itself in World War One recruitment centres, and in 1926, psychologist Lewis Terman decided to use it to identify and study a group of gifted children. Combing California’s schools for the creme de la creme, he selected 1,500 pupils with an IQ of 140 or more – 80 of whom had IQs above 170. Together, they became known as the “Termites”, and the highs and lows of their lives are still being studied to this day.
  • The harsh truth, however, is that greater intelligence does not equate to wiser decisions; in fact, in some cases it might make your choices a little more foolish. Keith Stanovich at the University of Toronto has spent the last decade building tests for rationality, and he has found that fair, unbiased decision-making is largely independent of IQ. Consider the “my-side bias” – our tendency to be highly selective in the information we collect so that it reinforces our previous attitudes. The more enlightened approach would be to leave your assumptions at the door as you build your argument – but Stanovich found that smarter people are almost no more likely to do so than people with distinctly average IQs.
  • A tendency to rely on gut instincts rather than rational thought might also explain why a surprisingly high number of Mensa members believe in the paranormal; or why someone with an IQ of 140 is about twice as likely to max out their credit card.Indeed, Stanovich sees these biases in every strata of society. “There is plenty of dysrationalia – people doing irrational things despite more than adequate intelligence – in our world today,” he says. “The people pushing the anti-vaccination meme on parents and spreading misinformation on websites are generally of more than average intelligence and education.” Clearly, clever people can be dangerously, and foolishly, misguided.

The Problem With History Classes - Atlantic Mobile - 1 views

  • Currently, most students learn history as a set narrative—a process that reinforces the mistaken idea that the past can be synthesized into a single, standardized chronicle of several hundred pages. This teaching pretends that there is a uniform collective story, which is akin to saying everyone remembers events the same. Yet, history is anything but agreeable. It is not a collection of facts deemed to be "official" by scholars on high. It is a collection of historians exchanging different, often conflicting analyses. And rather than vainly seeking to transcend the inevitable clash of memories, American students would be better served by descending into the bog of conflict and learning the many "histories" that compose the American national story.
  • History may be an attempt to memorialize and preserve the past, but it is not memory; memories can serve as primary sources, but they do not stand alone as history. A history is essentially a collection of memories, analyzed and reduced into meaningful conclusions—but that collection depends on the memories chosen.
  • Although, as Urist notes, the AP course is "designed to teach students to think like historians," my own experience in that class suggests that it fails to achieve that goal. The course’s framework has always served as an outline of important concepts aiming to allow educators flexibility in how to teach; it makes no reference to historiographical conflicts. Historiography was an epiphany for me because I had never before come face-to-face with how historians think and reason—how they construct an argument, what sources animate that approach, and how their position responds to other historians. When I took AP U.S. History, I jumbled these diverse histories into one indistinct narrative. Although the test involved open-ended essay questions, I was taught that graders were looking for a firm thesis—forcing students to adopt a side. The AP test also, unsurprisingly, rewards students who cite a wealth of supporting details. By the time I took the test in 2009, I was a master at "checking boxes," weighing political factors equally against those involving socioeconomics and ensuring that previously neglected populations like women and ethnic minorities received their due. I did not know that I was pulling ideas from different historiographical traditions. I still subscribed to the idea of a prevailing national narrative and served as an unwitting sponsor of synthesis, oblivious to the academic battles that made such synthesis impossible.

The Fake-Tongue Illusion - The New Yorker - 2 views

  • 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).

'Who Speaks Wukchumni?' - NYTimes.com - 0 views

  • Throughout the United States, many Native American languages are struggling to survive. According to Unesco, more than 130 of these languages are currently at risk, with 74 languages considered “critically endangered.” These languages preserve priceless cultural heritage, and some hold unexpected value — nuances in these languages convey unparalleled knowledge of the natural world. Many of these at-risk languages are found in my home state of California. Now for some, only a few fluent speakers remain.

The Irrationality Myth | Big Think | Praxis - 0 views

  • There is indeed ample data that institutions and individuals can wreak havoc when they deviate from certain principles of logic and objectivity. There is also a good deal of dispiriting evidence about the rationality of voters that spurs questions about the effectiveness—and even the legitimacy—of democratic government. Yet much of the work of cognitive scientists—even fascinating Nobel Prize-winning research by Daniel Kahneman—leaves me edified but not alarmed. The human capacity for reason may be fragile and partial but it is not belied by studies in which large percentages of subjects answer a few tricky questions incorrectly.
  • My hypothesis is that while we love reading about humanity’s tendency toward the irrational, we take offense when light is thrown on our own individual incompetencies.

"Cyranoids": Stanley Milgram's Creepiest Experiment - Neuroskeptic | DiscoverMagazine.com - 1 views

  • Imagine that someone else was controlling your actions. You would still look like you, and sound like you, but you wouldn’t be the one deciding what you did and what you said. Now consider: would anyone notice the difference?
  • If I started shadowing someone else’s speech, would my friends and family notice? I would like to think so. Most of us would like to think so. But how easy would it be? Do we really listen to each others’ words, after all, or do we just assume that because person X is speaking, they must be saying the kind of thing that person X likes to say? We’re getting into some uncomfortable territory here.

BBC News - China: Stroke patient loses Chinese language ability - 0 views

  • An elderly Chinese woman is only able to speak English after suffering a stroke, it's been reported. Liu Jaiyu, a 94-year-old former English teacher, has found herself no longer able to speak Chinese after parts of her brain relating to native language were damaged by a cerebral infarction, the local Hunan TV reports. Television pictures show her in bed, answering simple questions in English, which means the nursing staff are having to brush up on their language skills. "She greets me in the morning using English, after she's eaten her meals in the afternoon she uses English," one nurse tells the TV. "My memory of the language isn't too good, sometimes I don't understand what she's saying!" A doctor at the hospital says that Ms Liu is suffering from paralysis of all her limbs, as well as an "obstacle" to her language functions. "It seems the part of her brain responsible for her mother tongue has been damaged, however the part that uses English has been preserved," Li Yanfang says. There have been rare cases where patients develop a different accent after a stroke, migraine or head trauma. But Ms Liu's case appears different because she has apparently turned to an already-learned language. Experts say that the complex Chinese language requires the use of both parts of the brain, while English only uses one side.

Why Cambodians Never Get 'Depressed' : Goats and Soda : NPR - 0 views

  • People in Cambodia experience what we Americans call depression. But there's no direct translation for the word "depression" in the Cambodian Khmer language. Instead, people may say thelea tdeuk ceut, which literally means "the water in my heart has fallen." Anxious or depressed Haitians, on the other hand, may use the phrase reflechi twop, which means "thinking too much." And in parts of Nepal and India, people use the English word "tension."
  • But just as words for depression and anxiety get lost in translation, so can treatments.

BBC - Culture - Eleven untranslatable words - 1 views

  • There is one clear difference, though: Iyer has not invented them. The definitions she illustrates – 60 so far, from 30 different languages – match The Meaning of Liff for absurdity, but all of them are real. There is komorebi, Japanese for ‘the sort of scattered dappled light effect that happens when sunlight shines in through trees’; or rire dans sa barbe, a French expression meaning ‘to laugh in your beard quietly while thinking about something that happened in the past’.
  • Iyer’s Found in Translation project will be published as a book later in 2014. She has been a polyglot since childhood. “My parents come from different parts of India, so I grew up learning five languages,” she says. “I’d always loved the word Fernweh, which is German for ‘longing for a place you’ve never been to’, and then one day I started collecting more.”Some are humorous, while others have definitions that read like poetry. “I love the German word Waldeinsamkeit, ‘the feeling of being alone in the woods’. “It captures a sense of solitude and at the same time that feeling of oneness with nature.” Her favourite is the Inuit word Iktsuarpok, which means ‘the frustration of waiting for someone to turn up’, because “it holds so much meaning. It’s waiting, whether you are waiting for the bus to show up or for the love of your life. It perfectly describes that inner anguish associated with waiting.”

Teaching Doubt - The New Yorker - 0 views

  • “Non-overlapping magisteria” has a nice ring to it. The problem is that there are many religious claims that not only “overlap” with empirical data but are incompatible with it. As a scientist who also spends a fair amount of time in the public arena, if I am asked if our understanding of the Big Bang conflicts with the idea of a six-thousand-year-old universe, I face a choice: I can betray my scientific values, or encourage that person to doubt his or her own beliefs. More often than you might think, teaching science is inseparable from teaching doubt.
  • Doubt about one’s most cherished beliefs is, of course, central to science: the physicist Richard Feynman stressed that the easiest person to fool is oneself. But doubt is also important to non-scientists. It’s good to be skeptical, especially about ideas you learn from perceived authority figures. Recent studies even suggest that being taught to doubt at a young age could make people better lifelong learners. That, in turn, means that doubters—people who base their views on evidence, rather than faith—are likely to be better citizens.
  • Science class isn’t the only place where students can learn to be skeptical. A provocative novel that presents a completely foreign world view, or a history lesson exploring the vastly different mores of the past, can push you to skeptically reassess your inherited view of the universe. But science is a place where such confrontation is explicit and accessible. It didn’t take more than a simple experiment for Galileo to overturn the wisdom of Aristotle. Informed doubt is the very essence of science.

  • Some teachers shy away from confronting religious beliefs because they worry that planting the seeds of doubt will cause some students to question or abandon their own faith or the faith of their parents. But is that really such a bad thing? It offers some young people the chance to escape the guilt imposed upon them simply for questioning what they’re told. Last year, I received an e-mail from a twenty-seven-year-old man who is now studying in the United States after growing up in Saudi Arabia. His father was executed by family members after converting to Christianity. He says that it’s learning about science that has finally liberated him from the spectre of religious fundamentalism.
