Mitt Romney's Problem Speaking About Money - NYTimes.com - 0 views

  • Why is someone who is so good at making money so bad at talking about it?Mitt Romney is not the first presidential candidate who’s had trouble communicating with working-class voters: John Kerry famously enjoyed wind-surfing, and George Bush blamed a poor showing in a straw poll on the fact that many of his supporters were “at their daughter’s coming out party.”Veritable battalions of Kennedys and Roosevelts have dealt with the economic and cultural gaps between themselves and the voters over the years without much difficulty. Not so Barack Obama, whose attempt to commiserate with Iowa farmers in 2007 about crop prices by mentioning the cost of arugula at Whole Foods fell flat.
  • Romney’s reference last week to the fact that his wife “drives a couple of Cadillacs, actually” is not grounds in itself for a voter to oppose his candidacy. Neither was the $10,000 bet he offered to Rick Perry during a debate in December or the time he told a group of the unemployed in Florida that he was “also unemployed.”But his penchant for awkward references to his own wealth has underscored the suspicion that many voters have about his ability to understand their economic problems. His opponents in both parties  are gleefully highlighting these moments as a way to drive a wedge between Romney and the working class voters who have become an increasingly important part of the Republican Party base.
  • The current economic circumstances have undoubtedly exacerbated the problem for Romney. Had Obama initially sought the presidency during a primary season dominated by concerns about the domestic economy rather than war in Iraq, his explanation that small town voters “get bitter, they cling to guns or religion or antipathy to people who aren’t like them” might have created an opportunity for Hillary Clinton or even the populist message of John Edwards.

  • But Obama’s early opposition to the Iraq war gave him a political firewall that protected him throughout that primary campaign, while Romney has no such policy safe harbor to safeguard him from an intramural backlash.
  • Romney and Obama share a lack of natural affinity for this key group of swing voters, but it is Romney who needs to figure out some way of addressing this shortcoming if he wants to make it to the White House. It’s Romney’s misfortune that the voters’ prioritization of economic issues, his own privileged upbringing and his lack of connection with his party’s base on other core issues put him in a much more precarious position than candidate Obama ever reached.
  • By the time the 2008 general election rolled around, Obama had bolstered his outreach to these voters by recruiting the blue-collar avatar Joe Biden as his running mate. Should Romney win the Republican nomination this year, his advisers will almost certainly be tempted by the working-class credentials that a proletarian like New Jersey Governor Chris Christie or Florida Senator Marco Rubio would bring to the ticket.
  • Of more immediate concern to Team Romney should be how their candidate can overcome his habit of economic tone-deafness before Rick Santorum steals away enough working-class and culturally conservative voters to throw the Republican primary into complete and utter turmoil.
  • The curious thing about Romney’s verbal missteps is how limited they are to this very specific area of public policy. He is usually quite articulate when talking about foreign affairs and national security. Despite his complicated history on social and cultural matters like health care and abortion, his explanations are usually both coherent and comprehensible, even to those who oppose his positions. It’s only when he begins talking about economic issues – his biographical strength – that he seems to get clumsy.
  • The second possibility would be for him to outline a series of proposals specifically targeted at the needs of working-class and poor Americans, not only to control the damage from his gaffes but also to underscore the conservative premise that a right-leaning agenda will create opportunities for those on the lower rungs of the economic ladder. But while that approach might help Romney in a broader philosophical conversation, it’s unlikely to offer him much protection from the attacks and ridicule that his unforced errors will continue to bring him.
  • The question is why Romney hasn’t embraced a third alternative – admitting the obvious and then explaining why he gets so tongue-tied when the conversation turns to money. Romney’s upbringing and religious faith suggest a sense of obligation to the less fortunate and an unspoken understanding that it isn’t appropriate to call attention to one’s financial success.It wouldn’t be that hard for him to say something like:I was taught not to brag and boast and think I’m better than other people because of the successes I’ve had, so occasionally I’m going to say things that sound awkward. It’s because I’d rather talk about what it takes to get America back to work.

The Dangers of Pseudoscience - NYTimes.com - 0 views

  • the “demarcation problem,” the issue of what separates good science from bad science and pseudoscience (and everything in between). The problem is relevant for at least three reasons.
  • The first is philosophical: Demarcation is crucial to our pursuit of knowledge; its issues go to the core of debates on epistemology and of the nature of truth and discovery.
  • The second reason is civic: our society spends billions of tax dollars on scientific research, so it is important that we also have a good grasp of what constitutes money well spent in this regard.
  • ...18 more annotations...
  • Third, as an ethical matter, pseudoscience is not — contrary to popular belief — merely a harmless pastime of the gullible; it often threatens people’s welfare,
  • It is precisely in the area of medical treatments that the science-pseudoscience divide is most critical, and where the role of philosophers in clarifying things may be most relevant.
  • some traditional Chinese remedies (like drinking fresh turtle blood to alleviate cold symptoms) may in fact work
  • There is no question that some folk remedies do work. The active ingredient of aspirin, for example, is derived from willow bark, which had been known to have beneficial effects since the time of Hippocrates. There is also no mystery about how this happens: people have more or less randomly tried solutions to their health problems for millennia, sometimes stumbling upon something useful
  • What makes the use of aspirin “scientific,” however, is that we have validated its effectiveness through properly controlled trials, isolated the active ingredient, and understood the biochemical pathways through which it has its effects
  • In terms of empirical results, there are strong indications that acupuncture is effective for reducing chronic pain and nausea, but sham therapy, where needles are applied at random places, or are not even pierced through the skin, turn out to be equally effective (see for instance this recent study on the effect of acupuncture on post-chemotherapy chronic fatigue), thus seriously undermining talk of meridians and Qi lines
  • Asma at one point compares the current inaccessibility of Qi energy to the previous (until this year) inaccessibility of the famous Higgs boson,
  • But the analogy does not hold. The existence of the Higgs had been predicted on the basis of a very successful physical theory known as the Standard Model. This theory is not only exceedingly mathematically sophisticated, but it has been verified experimentally over and over again. The notion of Qi, again, is not really a theory in any meaningful sense of the word. It is just an evocative word to label a mysterious force
  • Philosophers of science have long recognized that there is nothing wrong with positing unobservable entities per se, it’s a question of what work such entities actually do within a given theoretical-empirical framework. Qi and meridians don’t seem to do any, and that doesn’t seem to bother supporters and practitioners of Chinese medicine. But it ought to.
  • what’s the harm in believing in Qi and related notions, if in fact the proposed remedies seem to help?
  • we can incorporate whatever serendipitous discoveries from folk medicine into modern scientific practice, as in the case of the willow bark turned aspirin. In this sense, there is no such thing as “alternative” medicine, there’s only stuff that works and stuff that doesn’t.
  • Second, if we are positing Qi and similar concepts, we are attempting to provide explanations for why some things work and others don’t. If these explanations are wrong, or unfounded as in the case of vacuous concepts like Qi, then we ought to correct or abandon them.
  • pseudo-medical treatments often do not work, or are even positively harmful. If you take folk herbal “remedies,” for instance, while your body is fighting a serious infection, you may suffer severe, even fatal, consequences.
  • Indulging in a bit of pseudoscience in some instances may be relatively innocuous, but the problem is that doing so lowers your defenses against more dangerous delusions that are based on similar confusions and fallacies. For instance, you may expose yourself and your loved ones to harm because your pseudoscientific proclivities lead you to accept notions that have been scientifically disproved, like the increasingly (and worryingly) popular idea that vaccines cause autism.
  • Philosophers nowadays recognize that there is no sharp line dividing sense from nonsense, and moreover that doctrines starting out in one camp may over time evolve into the other. For example, alchemy was a (somewhat) legitimate science in the times of Newton and Boyle, but it is now firmly pseudoscientific (movements in the opposite direction, from full-blown pseudoscience to genuine science, are notably rare).
  • The verdict by philosopher Larry Laudan, echoed by Asma, that the demarcation problem is dead and buried, is not shared by most contemporary philosophers who have studied the subject.
  • the criterion of falsifiability, for example, is still a useful benchmark for distinguishing science and pseudoscience, as a first approximation. Asma’s own counterexample inadvertently shows this: the “cleverness” of astrologers in cherry-picking what counts as a confirmation of their theory, is hardly a problem for the criterion of falsifiability, but rather a nice illustration of Popper’s basic insight: the bad habit of creative fudging and finagling with empirical data ultimately makes a theory impervious to refutation. And all pseudoscientists do it, from parapsychologists to creationists and 9/11 Truthers.
  • The borderlines between genuine science and pseudoscience may be fuzzy, but this should be even more of a call for careful distinctions, based on systematic facts and sound reasoning. To try a modicum of turtle blood here and a little aspirin there is not the hallmark of wisdom and even-mindedness. It is a dangerous gateway to superstition and irrationality.

Love People, Not Pleasure - NYTimes.com - 0 views

  • Fame, riches and pleasure beyond imagination. Sound great? He went on to write:“I have diligently numbered the days of pure and genuine happiness which have fallen to my lot: They amount to 14.”Abd al-Rahman’s problem wasn’t happiness, as he believed — it was unhappiness
  • Happiness and unhappiness are certainly related, but they are not actually opposites.
  • Circumstances are certainly important. No doubt Abd al-Rahman could point to a few in his life. But paradoxically, a better explanation for his unhappiness may have been his own search for well-being. And the same might go for you.Continue reading the main story

  • As strange as it seems, being happier than average does not mean that one can’t also be unhappier than average.
  • In 2009, researchers from the University of Rochester conducted a study tracking the success of 147 recent graduates in reaching their stated goals after graduation. Some had “intrinsic” goals, such as deep, enduring relationships. Others had “extrinsic” goals, such as achieving reputation or fame. The scholars found that intrinsic goals were associated with happier lives. But the people who pursued extrinsic goals experienced more negative emotions, such as shame and fear. They even suffered more physical maladies.
  • the paradox of fame. Just like drugs and alcohol, once you become addicted, you can’t live without it. But you can’t live with it, either.
  • That impulse to fame by everyday people has generated some astonishing innovations.
  • Today, each of us can build a personal little fan base, thanks to Facebook, YouTube, Twitter and the like. We can broadcast the details of our lives to friends and strangers in an astonishingly efficient way. That’s good for staying in touch with friends, but it also puts a minor form of fame-seeking within each person’s reach. And several studies show that it can make us unhappy.
  • It makes sense. What do you post to Facebook? Pictures of yourself yelling at your kids, or having a hard time at work? No, you post smiling photos of a hiking trip with friends. You build a fake life — or at least an incomplete one — and share it. Furthermore, you consume almost exclusively the fake lives of your social media “friends.” Unless you are extraordinarily self-aware, how could it not make you feel worse to spend part of your time pretending to be happier than you are, and the other part of your time seeing how much happier others seem to be than you?Continue reading the main story
  • the bulk of the studies point toward the same important conclusion: People who rate materialistic goals like wealth as top personal priorities are significantly likelier to be more anxious, more depressed and more frequent drug users, and even to have more physical ailments than those who set their sights on more intrinsic values.
  • as the Dalai Lama pithily suggests, it is better to want what you have than to have what you want.
  • In 2004, two economists looked into whether more sexual variety led to greater well-being. They looked at data from about 16,000 adult Americans who were asked confidentially how many sex partners they had had in the preceding year, and about their happiness. Across men and women alike, the data show that the optimal number of partners is one.
  • This might seem totally counterintuitive. After all, we are unambiguously driven to accumulate material goods, to seek fame, to look for pleasure. How can it be that these very things can give us unhappiness instead of happiness? There are two explanations, one biological and the other philosophical.
  • From an evolutionary perspective, it makes sense that we are wired to seek fame, wealth and sexual variety. These things make us more likely to pass on our DNA.
  • here’s where the evolutionary cables have crossed: We assume that things we are attracted to will relieve our suffering and raise our happiness.
  • that is Mother Nature’s cruel hoax. She doesn’t really care either way whether you are unhappy — she just wants you to want to pass on your genetic material. If you conflate intergenerational survival with well-being, that’s your problem, not nature’s.
  • More philosophically, the problem stems from dissatisfaction — the sense that nothing has full flavor, and we want more. We can’t quite pin down what it is that we seek. Without a great deal of reflection and spiritual hard work, the likely candidates seem to be material things, physical pleasures or favor among friends and strangers.
  • We look for these things to fill an inner emptiness. They may bring a brief satisfaction, but it never lasts, and it is never enough. And so we crave more.
  • This search for fame, the lust for material things and the objectification of others — that is, the cycle of grasping and craving — follows a formula that is elegant, simple and deadly:Love things, use people.
  • This was Abd al-Rahman’s formula as he sleepwalked through life. It is the worldly snake oil peddled by the culture makers from Hollywood to Madison Avenue.
  • Simply invert the deadly formula and render it virtuous:Love people, use things.
  • It requires the courage to repudiate pride and the strength to love others — family, friends, colleagues, acquaintances, God and even strangers and enemies. Only deny love to things that actually are objects. The practice that achieves this is charity. Few things are as liberating as giving away to others that which we hold dear.
  • This also requires a condemnation of materialism.
  • Finally, it requires a deep skepticism of our own basic desires. Of course you are driven to seek admiration, splendor and physical license.
  • Declaring war on these destructive impulses is not about asceticism or Puritanism. It is about being a prudent person who seeks to avoid unnecessary suffering.

  • Medieval science was guided by "logical consistency."
  • The logical empiricist's conception of scientific progress was thus a continuous one; more comprehensive theory replaced compatible, older theory
  • Hempel also believed that science evolved in a continuous manner. New theory did not contradict past theory: "theory does not simply refute the earlier empirical generalizations in its field; rather, it shows that within a certain limited range defined by qualifying conditions, the generalizations hold true in fairly close approximation." [21]

  • he entities and processes of theory were believed to exist in nature, and science should discover those entities and processes

  • Unlike evolutionary science, in which new knowledge fills a gap of ignorance, in Kuhn's model new knowledge replaces incompatible knowledge.
  • Thus science is not a continuous or cumulative endeavor: when a paradigm shift occurs there is a revolution similar to a political revolution, with fundamental and pervasive changes in method and understanding. Each successive vision about the nature of the universe makes the past vision obsolete; predictions, though more precise, remain similar to the predictions of the past paradigm in their general orientation, but the new explanations do not accommodate the old
  • In a sense, we have circled back to the ancient and medieval practice of separating scientific theory from physical reality; both medieval scientists and Kuhn would agree that no theory corresponds to reality and therefore any number of theories might equally well explain a natural phenomenon. [36] Neither twentieth-century atomic theorists nor medieval astronomers are able to claim that their theories accurately describe physical phenomena. The inability to return to scientific realism suggests a tripartite division of the history of science, with a period of scientific realism fitting between two periods in which there is no insistence that theory correspond to reality. Although both scientific realism and the evolutionary idea of scientific progress appeal to common sense, both existed for only a few hundred years.

Underweight people face significantly higher risk of dementia, study suggests | Society | The Guardian - 0 views

  • The best protection against dementia, he added, is “eating a healthy, balanced diet, exercising regularly, not smoking, and keeping blood pressure in check”.

Noam Chomsky on Where Artificial Intelligence Went Wrong - Yarden Katz - The Atlantic - 1 views

  • Skinner's approach stressed the historical associations between a stimulus and the animal's response -- an approach easily framed as a kind of empirical statistical analysis, predicting the future as a function of the past.
  • Chomsky's conception of language, on the other hand, stressed the complexity of internal representations, encoded in the genome, and their maturation in light of the right data into a sophisticated computational system, one that cannot be usefully broken down into a set of associations.
  • Behaviorist principles of associations could not explain the richness of linguistic knowledge, our endlessly creative use of it, or how quickly children acquire it with only minimal and imperfect exposure to language presented by their environment.
  • ...17 more annotations...
  • David Marr, a neuroscientist colleague of Chomsky's at MIT, defined a general framework for studying complex biological systems (like the brain) in his influential book Vision,
  • a complex biological system can be understood at three distinct levels. The first level ("computational level") describes the input and output to the system, which define the task the system is performing. In the case of the visual system, the input might be the image projected on our retina and the output might our brain's identification of the objects present in the image we had observed. The second level ("algorithmic level") describes the procedure by which an input is converted to an output, i.e. how the image on our retina can be processed to achieve the task described by the computational level. Finally, the third level ("implementation level") describes how our own biological hardware of cells implements the procedure described by the algorithmic level.
  • The emphasis here is on the internal structure of the system that enables it to perform a task, rather than on external association between past behavior of the system and the environment. The goal is to dig into the "black box" that drives the system and describe its inner workings, much like how a computer scientist would explain how a cleverly designed piece of software works and how it can be executed on a desktop computer.
  • As written today, the history of cognitive science is a story of the unequivocal triumph of an essentially Chomskyian approach over Skinner's behaviorist paradigm -- an achievement commonly referred to as the "cognitive revolution,"
  • While this may be a relatively accurate depiction in cognitive science and psychology, behaviorist thinking is far from dead in related disciplines. Behaviorist experimental paradigms and associationist explanations for animal behavior are used routinely by neuroscientists
  • Chomsky critiqued the field of AI for adopting an approach reminiscent of behaviorism, except in more modern, computationally sophisticated form. Chomsky argued that the field's heavy use of statistical techniques to pick regularities in masses of data is unlikely to yield the explanatory insight that science ought to offer. For Chomsky, the "new AI" -- focused on using statistical learning techniques to better mine and predict data -- is unlikely to yield general principles about the nature of intelligent beings or about cognition.
  • Chomsky acknowledged that the statistical approach might have practical value, just as in the example of a useful search engine, and is enabled by the advent of fast computers capable of processing massive data. But as far as a science goes, Chomsky would argue it is inadequate, or more harshly, kind of shallow
  • An unlikely pair, systems biology and artificial intelligence both face the same fundamental task of reverse-engineering a highly complex system whose inner workings are largely a mystery
  • Implicit in this endeavor is the assumption that with enough sophisticated statistical tools and a large enough collection of data, signals of interest can be weeded it out from the noise in large and poorly understood biological systems.
  • Brenner, a contemporary of Chomsky who also participated in the same symposium on AI, was equally skeptical about new systems approaches to understanding the brain. When describing an up-and-coming systems approach to mapping brain circuits called Connectomics, which seeks to map the wiring of all neurons in the brain (i.e. diagramming which nerve cells are connected to others), Brenner called it a "form of insanity."
  • These debates raise an old and general question in the philosophy of science: What makes a satisfying scientific theory or explanation, and how ought success be defined for science?
  • Ever since Isaiah Berlin's famous essay, it has become a favorite pastime of academics to place various thinkers and scientists on the "Hedgehog-Fox" continuum: the Hedgehog, a meticulous and specialized worker, driven by incremental progress in a clearly defined field versus the Fox, a flashier, ideas-driven thinker who jumps from question to question, ignoring field boundaries and applying his or her skills where they seem applicable.
  • Chomsky's work has had tremendous influence on a variety of fields outside his own, including computer science and philosophy, and he has not shied away from discussing and critiquing the influence of these ideas, making him a particularly interesting person to interview.
  • If you take a look at the progress of science, the sciences are kind of a continuum, but they're broken up into fields. The greatest progress is in the sciences that study the simplest systems. So take, say physics -- greatest progress there. But one of the reasons is that the physicists have an advantage that no other branch of sciences has. If something gets too complicated, they hand it to someone else.
  • If a molecule is too big, you give it to the chemists. The chemists, for them, if the molecule is too big or the system gets too big, you give it to the biologists. And if it gets too big for them, they give it to the psychologists, and finally it ends up in the hands of the literary critic, and so on.
  • it has been argued in my view rather plausibly, though neuroscientists don't like it -- that neuroscience for the last couple hundred years has been on the wrong track.
  • neuroscience developed kind of enthralled to associationism and related views of the way humans and animals work. And as a result they've been looking for things that have the properties of associationist psychology.

Opinion | Is There Such a Thing as an Authoritarian Voter? - The New York Times - 0 views

  • Jonathan Weiler, a political scientist at the University of North Carolina at Chapel Hill, has spent much of his career studying the appeal of authoritarian figures: politicians who preach xenophobia, beat up on the press and place themselves above the law while extolling “law and order” for everyone else.
  • He is one of many scholars who believe that deep-seated psychological traits help explain voters’ attraction to such leaders. “These days,” he told me, “audiences are more receptive to the idea” than they used to be.
  • “In 2018, the sense of fear and panic — the disorientation about how people who are not like us could see the world the way they do — it’s so elemental,” Mr. Weiler said. “People understand how deeply divided we are, and they are looking for explanations that match the depth of that division.”

Why facts don't matter to Trump's supporters - The Washington Post - 3 views

  • How did Donald Trump win the Republican nomination, despite clear evidence that he had misrepresented or falsified key issues throughout the campaign? Social scientists have some intriguing explanations for why people persist in misjudgments despite strong contrary evidence.
  • studies show that attempts to refute false information often backfire and lead people to hold on to their misperceptions even more strongly.
  • Graves’s article examined the puzzle of why nearly one-third of U.S. parents believe that childhood vaccines cause autism, despite overwhelming medical evidence that there’s no such link. In such cases, he noted, “arguing the facts doesn’t help — in fact, it makes the situation worse.” The reason is that people tend to accept arguments that confirm their views and discount facts that challenge what they believe.

  • Trying to correct misperceptions can actually reinforce them, according to a 2006 paper by Brendan Nyhan and Jason Reifler, also cited by Graves. They documented what they called a “backfire effect” by showing the persistence of the belief that Iraq had weapons of mass destruction in 2005
  • “The results show that direct factual contradictions can actually strengthen ideologically grounded factual belief,” they wrote.
  • people remember the assertion and forget whether it’s a lie. The authors wrote: “The more often older adults were told that a given claim was false, the more likely they were to accept it as true after several days have passed.”
  • When critics challenge false assertions — say, Trump’s claim that thousands of Muslims cheered in New Jersey when the twin towers fell on Sept. 11, 2001 — their refutations can threaten people, rather than convince them. Graves noted that if people feel attacked, they resist the facts all the more
  • The study showed two interesting things: People are more likely to accept information if it’s presented unemotionally, in graphs;
  • and they’re even more accepting if the factual presentation is accompanied by “affirmation” that asks respondents to recall an experience that made them feel good about themselves.
  • Bottom line: Vilifying Trump voters — or, alternatively, parents who don’t want to have their children vaccinated — won’t convince them they’re wrong. Probably it will have the opposite effect.
  • The final point that emerged from Graves’s survey is that people will resist abandoning a false belief unless they have a compelling alternative explanation. That point was made in an article called “The Debunking Handbook,” by Australian researchers John Cook and Stephan Lewandowsky. They wrote: “Unless great care is taken, any effort to debunk misinformation can inadvertently reinforce the very myths one seeks to correct.”
  • Trump’s campaign pushes buttons that social scientists understand. When the GOP nominee paints a dark picture of a violent, frightening America, he triggers the “fight or flight” response that’s hardwired in our brains. For the body politic, it can produce a kind of panic attack.

You're Not Going to Change Your Mind - The New York Times - 0 views

  • A troubling feature of political disagreement in the United States today is that many issues on which liberals and conservatives hold divergent views are questions not of value but of fact. Is human activity responsible for global warming? Do guns make society safer? Is immigration harmful to the economy? Though undoubtedly complicated, these questions turn on empirical evidence.
  • Unfortunately, people do not always revise their beliefs in light of new information. On the contrary, they often stubbornly maintain their views. Certain disagreements stay entrenched and polarized.
  • A common explanation is confirmation bias

  • the psychological tendency to favor information that confirms our beliefs
  • If this explanation is right, then there is a relatively straightforward solution to political polarization: We need to consciously expose ourselves to evidence that challenges our beliefs to compensate for our inclination to discount it.
  • But what if confirmation bias isn’t the only culprit? It recently struck us that confirmation bias is often conflated with “telling people what they want to hear,” which is actually a distinct phenomenon known as desirability bias, or the tendency to credit information you want to believe.
  • we decided to conduct an experiment that would isolate these biases
  • The results, which we report in a forthcoming paper in the Journal of Experimental Psychology: General, were clear and robust. Those people who received desirable evidence — polls suggesting that their preferred candidate was going to win — took note and incorporated the information into their subsequent belief
  • . In contrast, those people who received undesirable evidence barely changed their belief about which candidate was most likely to win.
  • we observed a general bias toward the desirable evidence.
  • What about confirmation bias? To our surprise, those people who received confirming evidence — polls supporting their prior belief about which candidate was most likely to win — showed no bias in favor of this information.
  • They tended to incorporate this evidence into their subsequent belief to the same extent as those people who had their prior belief disconfirmed. In other words, we observed little to no bias toward the confirming evidence.
  • Our study suggests that political belief polarization may emerge because of peoples’ conflicting desires, not their conflicting beliefs per se
  • This is rather troubling, as it implies that even if we were to escape from our political echo chambers, it wouldn’t help much. Short of changing what people want to believe, we must find other ways to unify our perceptions of reality.

Why can we trust the information produced by scientific research? - The Science Behind It. - 0 views

  • Science relies on empirical evidence and testable explanations. By basing its conclusions on multiple lines of evidence drawn from experiments and observations, science seeks to build reliable knowledge and provide scientific explanations that people can use to better understand the world around them and inform their decision making.
  • Right. Scientific research is both an individual and a collective activity. Scientists may act on their own in gathering data and working out ideas. But they then need to convey to others their conclusions and the methods and evidence on which those conclusions are based. These observations and conclusions can be checked and extended by other scientists.

Frontiers | A Digital Nudge to Counter Confirmation Bias | Big Data - 1 views

  • Information disorder in current information ecosystems arises not only from the publication of “fake news,” but also from individuals' subjective reading of news and from their propagating news to others. Sometimes the difference between real and fake information is apparent. However, often a message is written to evoke certain emotions and opinions by taking partially true base stories and injecting false statements such that the information looks realistic. In addition, the perception of the trustworthiness of news is often influenced by confirmation bias. As a result, people often believe distorted or outright incorrect news and spread such misinformation further. For example, it was shown that in the months preceding the 2016 American presidential election, organizations from both Russia and Iran ran organized efforts to create such stories and spread them on Twitter and Facebook (Cohen, 2018). It is therefore important to raise internet users' awareness of such practices. Key to this is providing users with means to understand whether information should be trusted or not.
  • In this section, we discuss how social networks increase the spread of biased news and misinformation. We discuss confirmation bias, echo chambers and other factors that may subconsciously influence a person's opinion. We show how these processes can interact to form a vicious circle that favors the rise of untrustworthy sources. Often, when an individual thinks they know something, they are satisfied by an explanation that confirms their belief, without necessarily considering all possible other explanations, and regardless of the veracity of this information. This is confirmation bias in action. Nickerson (1998) defined it as the tendency of people to both seek and interpret evidence that supports an already-held belief.

How Do You Know When Society Is About to Fall Apart? - The New York Times - 1 views

  • Tainter seemed calm. He walked me through the arguments of the book that made his reputation, “The Collapse of Complex Societies,” which has for years been the seminal text in the study of societal collapse, an academic subdiscipline that arguably was born with its publication in 1988
  • It is only a mild overstatement to suggest that before Tainter, collapse was simply not a thing.
  • His own research has moved on; these days, he focuses on “sustainability.”
  • ...53 more annotations...
  • He writes with disarming composure about the factors that have led to the disintegration of empires and the abandonment of cities and about the mechanism that, in his view, makes it nearly certain that all states that rise will one day fall
  • societal collapse and its associated terms — “fragility” and “resilience,” “risk” and “sustainability” — have become the objects of extensive scholarly inquiry and infrastructure.
  • Princeton has a research program in Global Systemic Risk, Cambridge a Center for the Study of Existential Risk
  • even Tainter, for all his caution and reserve, was willing to allow that contemporary society has built-in vulnerabilities that could allow things to go very badly indeed — probably not right now, maybe not for a few decades still, but possibly sooner. In fact, he worried, it could begin before the year was over.
  • Plato, in “The Republic,” compared cities to animals and plants, subject to growth and senescence like any living thing. The metaphor would hold: In the early 20th century, the German historian Oswald Spengler proposed that all cultures have souls, vital essences that begin falling into decay the moment they adopt the trappings of civilization.
  • that theory, which became the heart of “The Collapse of Complex Societies.” Tainter’s argument rests on two proposals. The first is that human societies develop complexity, i.e. specialized roles and the institutional structures that coordinate them, in order to solve problems
  • All history since then has been “characterized by a seemingly inexorable trend toward higher levels of complexity, specialization and sociopolitical control.”
  • Eventually, societies we would recognize as similar to our own would emerge, “large, heterogeneous, internally differentiated, class structured, controlled societies in which the resources that sustain life are not equally available to all.”
  • Something more than the threat of violence would be necessary to hold them together, a delicate balance of symbolic and material benefits that Tainter calls “legitimacy,” the maintenance of which would itself require ever more complex structures, which would become ever less flexible, and more vulnerable, the more they piled up.
  • Social complexity, he argues, is inevitably subject to diminishing marginal returns. It costs more and more, in other words, while producing smaller and smaller profits.
  • Take Rome, which, in Tainter's telling, was able to win significant wealth by sacking its neighbors but was thereafter required to maintain an ever larger and more expensive military just to keep the imperial machine from stalling — until it couldn’t anymore.
  • This is how it goes. As the benefits of ever-increasing complexity — the loot shipped home by the Roman armies or the gentler agricultural symbiosis of the San Juan Basin — begin to dwindle, Tainter writes, societies “become vulnerable to collapse.”
  • haven’t countless societies weathered military defeats, invasions, even occupations and lengthy civil wars, or rebuilt themselves after earthquakes, floods and famines?
  • Only complexity, Tainter argues, provides an explanation that applies in every instance of collapse.
  • Complexity builds and builds, usually incrementally, without anyone noticing how brittle it has all become. Then some little push arrives, and the society begins to fracture.
  • A disaster — even a severe one like a deadly pandemic, mass social unrest or a rapidly changing climate — can, in Tainter’s view, never be enough by itself to cause collapse
  • The only precedent Tainter could think of, in which pandemic coincided with mass social unrest, was the Black Death of the 14th century. That crisis reduced the population of Europe by as much as 60 percent.
  • Whether any existing society is close to collapsing depends on where it falls on the curve of diminishing returns.
  • The United States hardly feels like a confident empire on the rise these days. But how far along are we?
  • Scholars of collapse tend to fall into two loose camps. The first, dominated by Tainter, looks for grand narratives and one-size-fits-all explanations
  • The second is more interested in the particulars of the societies they study
  • Patricia McAnany, who teaches at the University of North Carolina at Chapel Hill, has questioned the usefulness of the very concept of collapse — she was an editor of a 2010 volume titled “Questioning Collapse” — but admits to being “very, very worried” about the lack, in the United States, of the “nimbleness” that crises require of governments.
  • We’re too vested and tied to places.” Without the possibility of dispersal, or of real structural change to more equitably distribute resources, “at some point the whole thing blows. It has to.”
  • In Turchin’s case the key is the loss of “social resilience,” a society’s ability to cooperate and act collectively for common goals. By that measure, Turchin judges that the United States was collapsing well before Covid-19 hit. For the last 40 years, he argues, the population has been growing poorer and more unhealthy as elites accumulate more and more wealth and institutional legitimacy founders. “The United States is basically eating itself from the inside out,
  • Inequality and “popular immiseration” have left the country extremely vulnerable to external shocks like the pandemic, and to internal triggers like the killings of George Floyd
  • Societies evolve complexity, he argues, precisely to meet such challenges.
  • Eric H. Cline, who teaches at the George Washington University, argued in “1177 B.C.: The Year Civilization Collapsed” that Late Bronze Age societies across Europe and western Asia crumbled under a concatenation of stresses, including natural disasters — earthquakes and drought — famine, political strife, mass migration and the closure of trade routes. On their own, none of those factors would have been capable of causing such widespread disintegration, but together they formed a “perfect storm” capable of toppling multiple societies all at once.
  • Collapse “really is a matter of when,” he told me, “and I’m concerned that this may be the time.”
  • In “The Collapse of Complex Societies,” Tainter makes a point that echoes the concern that Patricia McAnany raised. “The world today is full,” Tainter writes. Complex societies occupy every inhabitable region of the planet. There is no escaping. This also means, he writes, that collapse, “if and when it comes again, will this time be global.” Our fates are interlinked. “No longer can any individual nation collapse. World civilization will disintegrate as a whole.”
  • If it happens, he says, it would be “the worst catastrophe in history.”
  • The quest for efficiency, he wrote recently, has brought on unprecedented levels of complexity: “an elaborate global system of production, shipping, manufacturing and retailing” in which goods are manufactured in one part of the world to meet immediate demands in another, and delivered only when they’re needed. The system’s speed is dizzying, but so are its vulnerabilities.
  • A more comprehensive failure of fragile supply chains could mean that fuel, food and other essentials would no longer flow to cities. “There would be billions of deaths within a very short period,” Tainter says.
  • If we sink “into a severe recession or a depression,” Tainter says, “then it will probably cascade. It will simply reinforce itself.”
  • Tainter tells me, he has seen “a definite uptick” in calls from journalists: The study of societal collapse suddenly no longer seems like a purely academic pursuit
  • Turchin is keenly aware of the essential instability of even the sturdiest-seeming systems. “Very severe events, while not terribly likely, are quite possible,” he says. When he emigrated from the U.S.S.R. in 1977, he adds, no one imagined the country would splinter into its constituent parts. “But it did.”
  • He writes of visions of “bloated bureaucracies” becoming the basis of “entire political careers.” Arms races, he observes, presented a “classic example” of spiraling complexity that provides “no tangible benefit for much of the population” and “usually no competitive advantage” either.
  • It is hard not to read the book through the lens of the last 40 years of American history, as a prediction of how the country might deteriorate if resources continued to be slashed from nearly every sector but the military, prisons and police.
  • The more a population is squeezed, Tainter warns, the larger the share that “must be allocated to legitimization or coercion.
  • And so it was: As U.S. military spending skyrocketed — to, by some estimates, a total of more than $1 trillion today from $138 billion in 1980 — the government would try both tactics, ingratiating itself with the wealthy by cutting taxes while dismantling public-assistance programs and incarcerating the poor in ever-greater numbers.
  • “As resources committed to benefits decline,” Tainter wrote in 1988, “resources committed to control must increase.”
  • The overall picture drawn by Tainter’s work is a tragic one. It is our very creativity, our extraordinary ability as a species to organize ourselves to solve problems collectively, that leads us into a trap from which there is no escaping
  • Complexity is “insidious,” in Tainter’s words. “It grows by small steps, each of which seems reasonable at the time.” And then the world starts to fall apart, and you wonder how you got there.
  • Perhaps collapse is not, actually, a thing. Perhaps, as an idea, it was a product of its time, a Cold War hangover that has outlived its usefulness, or an academic ripple effect of climate-change anxiety, or a feedback loop produced by some combination of the two
  • if you pay attention to people’s lived experience, and not just to the abstractions imposed by a highly fragmented archaeological record, a different kind of picture emerges.
  • Tainter’s understanding of societies as problem-solving entities can obscure as much as it reveals
  • Plantation slavery arose in order to solve a problem faced by the white landowning class: The production of agricultural commodities like sugar and cotton requires a great deal of backbreaking labor. That problem, however, has nothing to do with the problems of the people they enslaved. Which of them counts as “society”?
  • Since the beginning of the pandemic, the total net worth of America’s billionaires, all 686 of them, has jumped by close to a trillion dollars.
  • If societies are not in fact unitary, problem-solving entities but heaving contradictions and sites of constant struggle, then their existence is not an all-or-nothing game.
  • Collapse appears not as an ending, but a reality that some have already suffered — in the hold of a slave ship, say, or on a long, forced march from their ancestral lands to reservations faraway — and survived.
  • The current pandemic has already given many of us a taste of what happens when a society fails to meet the challenges that face it, when the factions that rule over it tend solely to their own problems
  • the real danger comes from imagining that we can keep living the way we always have, and that the past is any more stable than the present.
  • If you close your eyes and open them again, the periodic disintegrations that punctuate our history — all those crumbling ruins — begin to fade, and something else comes into focus: wiliness, stubbornness and, perhaps the strongest and most essential human trait, adaptability.
  • When one system fails, we build another. We struggle to do things differently, and we push on. As always, we have no other choice.

How Does Science Really Work? | The New Yorker - 1 views

  • I wanted to be a scientist. So why did I find the actual work of science so boring? In college science courses, I had occasional bursts of mind-expanding insight. For the most part, though, I was tortured by drudgery.
  • I’d found that science was two-faced: simultaneously thrilling and tedious, all-encompassing and narrow. And yet this was clearly an asset, not a flaw. Something about that combination had changed the world completely.
  • “Science is an alien thought form,” he writes; that’s why so many civilizations rose and fell before it was invented. In his view, we downplay its weirdness, perhaps because its success is so fundamental to our continued existence.
  • ...50 more annotations...
  • In school, one learns about “the scientific method”—usually a straightforward set of steps, along the lines of “ask a question, propose a hypothesis, perform an experiment, analyze the results.”
  • That method works in the classroom, where students are basically told what questions to pursue. But real scientists must come up with their own questions, finding new routes through a much vaster landscape.
  • Since science began, there has been disagreement about how those routes are charted. Two twentieth-century philosophers of science, Karl Popper and Thomas Kuhn, are widely held to have offered the best accounts of this process.
  • For Popper, Strevens writes, “scientific inquiry is essentially a process of disproof, and scientists are the disprovers, the debunkers, the destroyers.” Kuhn’s scientists, by contrast, are faddish true believers who promulgate received wisdom until they are forced to attempt a “paradigm shift”—a painful rethinking of their basic assumptions.
  • Working scientists tend to prefer Popper to Kuhn. But Strevens thinks that both theorists failed to capture what makes science historically distinctive and singularly effective.
  • Sometimes they seek to falsify theories, sometimes to prove them; sometimes they’re informed by preëxisting or contextual views, and at other times they try to rule narrowly, based on t
  • Why do scientists agree to this scheme? Why do some of the world’s most intelligent people sign on for a lifetime of pipetting?
  • Strevens thinks that they do it because they have no choice. They are constrained by a central regulation that governs science, which he calls the “iron rule of explanation.” The rule is simple: it tells scientists that, “if they are to participate in the scientific enterprise, they must uncover or generate new evidence to argue with”; from there, they must “conduct all disputes with reference to empirical evidence alone.”
  • , it is “the key to science’s success,” because it “channels hope, anger, envy, ambition, resentment—all the fires fuming in the human heart—to one end: the production of empirical evidence.”
  • Strevens arrives at the idea of the iron rule in a Popperian way: by disproving the other theories about how scientific knowledge is created.
  • The problem isn’t that Popper and Kuhn are completely wrong. It’s that scientists, as a group, don’t pursue any single intellectual strategy consistently.
  • Exploring a number of case studies—including the controversies over continental drift, spontaneous generation, and the theory of relativity—Strevens shows scientists exerting themselves intellectually in a variety of ways, as smart, ambitious people usually do.
  • “Science is boring,” Strevens writes. “Readers of popular science see the 1 percent: the intriguing phenomena, the provocative theories, the dramatic experimental refutations or verifications.” But, he says,behind these achievements . . . are long hours, days, months of tedious laboratory labor. The single greatest obstacle to successful science is the difficulty of persuading brilliant minds to give up the intellectual pleasures of continual speculation and debate, theorizing and arguing, and to turn instead to a life consisting almost entirely of the production of experimental data.
  • Ultimately, in fact, it was good that the geologists had a “splendid variety” of somewhat arbitrary opinions: progress in science requires partisans, because only they have “the motivation to perform years or even decades of necessary experimental work.” It’s just that these partisans must channel their energies into empirical observation. The iron rule, Strevens writes, “has a valuable by-product, and that by-product is data.”
  • Science is often described as “self-correcting”: it’s said that bad data and wrong conclusions are rooted out by other scientists, who present contrary findings. But Strevens thinks that the iron rule is often more important than overt correction.
  • Eddington was never really refuted. Other astronomers, driven by the iron rule, were already planning their own studies, and “the great preponderance of the resulting measurements fit Einsteinian physics better than Newtonian physics.” It’s partly by generating data on such a vast scale, Strevens argues, that the iron rule can power science’s knowledge machine: “Opinions converge not because bad data is corrected but because it is swamped.”
  • Why did the iron rule emerge when it did? Strevens takes us back to the Thirty Years’ War, which concluded with the Peace of Westphalia, in 1648. The war weakened religious loyalties and strengthened national ones.
  • Two regimes arose: in the spiritual realm, the will of God held sway, while in the civic one the decrees of the state were paramount. As Isaac Newton wrote, “The laws of God & the laws of man are to be kept distinct.” These new, “nonoverlapping spheres of obligation,” Strevens argues, were what made it possible to imagine the iron rule. The rule simply proposed the creation of a third sphere: in addition to God and state, there would now be science.
  • Strevens imagines how, to someone in Descartes’s time, the iron rule would have seemed “unreasonably closed-minded.” Since ancient Greece, it had been obvious that the best thinking was cross-disciplinary, capable of knitting together “poetry, music, drama, philosophy, democracy, mathematics,” and other elevating human disciplines.
  • We’re still accustomed to the idea that a truly flourishing intellect is a well-rounded one. And, by this standard, Strevens says, the iron rule looks like “an irrational way to inquire into the underlying structure of things”; it seems to demand the upsetting “suppression of human nature.”
  • Descartes, in short, would have had good reasons for resisting a law that narrowed the grounds of disputation, or that encouraged what Strevens describes as “doing rather than thinking.”
  • In fact, the iron rule offered scientists a more supple vision of progress. Before its arrival, intellectual life was conducted in grand gestures.
  • Descartes’s book was meant to be a complete overhaul of what had preceded it; its fate, had science not arisen, would have been replacement by some equally expansive system. The iron rule broke that pattern.
  • by authorizing what Strevens calls “shallow explanation,” the iron rule offered an empirical bridge across a conceptual chasm. Work could continue, and understanding could be acquired on the other side. In this way, shallowness was actually more powerful than depth.
  • it also changed what counted as progress. In the past, a theory about the world was deemed valid when it was complete—when God, light, muscles, plants, and the planets cohered. The iron rule allowed scientists to step away from the quest for completeness.
  • The consequences of this shift would become apparent only with time
  • In 1713, Isaac Newton appended a postscript to the second edition of his “Principia,” the treatise in which he first laid out the three laws of motion and the theory of universal gravitation. “I have not as yet been able to deduce from phenomena the reason for these properties of gravity, and I do not feign hypotheses,” he wrote. “It is enough that gravity really exists and acts according to the laws that we have set forth.”
  • What mattered, to Newton and his contemporaries, was his theory’s empirical, predictive power—that it was “sufficient to explain all the motions of the heavenly bodies and of our sea.”
  • Descartes would have found this attitude ridiculous. He had been playing a deep game—trying to explain, at a fundamental level, how the universe fit together. Newton, by those lights, had failed to explain anything: he himself admitted that he had no sense of how gravity did its work
  • Strevens sees its earliest expression in Francis Bacon’s “The New Organon,” a foundational text of the Scientific Revolution, published in 1620. Bacon argued that thinkers must set aside their “idols,” relying, instead, only on evidence they could verify. This dictum gave scientists a new way of responding to one another’s work: gathering data.
  • Quantum theory—which tells us that subatomic particles can be “entangled” across vast distances, and in multiple places at the same time—makes intuitive sense to pretty much nobody.
  • Without the iron rule, Strevens writes, physicists confronted with such a theory would have found themselves at an impasse. They would have argued endlessly about quantum metaphysics.
  • ollowing the iron rule, they can make progress empirically even though they are uncertain conceptually. Individual researchers still passionately disagree about what quantum theory means. But that hasn’t stopped them from using it for practical purposes—computer chips, MRI machines, G.P.S. networks, and other technologies rely on quantum physics.
  • One group of theorists, the rationalists, has argued that science is a new way of thinking, and that the scientist is a new kind of thinker—dispassionate to an uncommon degree.
  • As evidence against this view, another group, the subjectivists, points out that scientists are as hopelessly biased as the rest of us. To this group, the aloofness of science is a smoke screen behind which the inevitable emotions and ideologies hide.
  • At least in science, Strevens tells us, “the appearance of objectivity” has turned out to be “as important as the real thing.”
  • The subjectivists are right, he admits, inasmuch as scientists are regular people with a “need to win” and a “determination to come out on top.”
  • But they are wrong to think that subjectivity compromises the scientific enterprise. On the contrary, once subjectivity is channelled by the iron rule, it becomes a vital component of the knowledge machine. It’s this redirected subjectivity—to come out on top, you must follow the iron rule!—that solves science’s “problem of motivation,” giving scientists no choice but “to pursue a single experiment relentlessly, to the last measurable digit, when that digit might be quite meaningless.”
  • If it really was a speech code that instigated “the extraordinary attention to process and detail that makes science the supreme discriminator and destroyer of false ideas,” then the peculiar rigidity of scientific writing—Strevens describes it as “sterilized”—isn’t a symptom of the scientific mind-set but its cause.
  • The iron rule—“a kind of speech code”—simply created a new way of communicating, and it’s this new way of communicating that created science.
  • Other theorists have explained science by charting a sweeping revolution in the human mind; inevitably, they’ve become mired in a long-running debate about how objective scientists really are
  • In “The Knowledge Machine: How Irrationality Created Modern Science” (Liveright), Michael Strevens, a philosopher at New York University, aims to identify that special something. Strevens is a philosopher of science
  • Compared with the theories proposed by Popper and Kuhn, Strevens’s rule can feel obvious and underpowered. That’s because it isn’t intellectual but procedural. “The iron rule is focused not on what scientists think,” he writes, “but on what arguments they can make in their official communications.”
  • Like everybody else, scientists view questions through the lenses of taste, personality, affiliation, and experience
  • geologists had a professional obligation to take sides. Europeans, Strevens reports, tended to back Wegener, who was German, while scholars in the United States often preferred Simpson, who was American. Outsiders to the field were often more receptive to the concept of continental drift than established scientists, who considered its incompleteness a fatal flaw.
  • Strevens’s point isn’t that these scientists were doing anything wrong. If they had biases and perspectives, he writes, “that’s how human thinking works.”
  • Eddington’s observations were expected to either confirm or falsify Einstein’s theory of general relativity, which predicted that the sun’s gravity would bend the path of light, subtly shifting the stellar pattern. For reasons having to do with weather and equipment, the evidence collected by Eddington—and by his colleague Frank Dyson, who had taken similar photographs in Sobral, Brazil—was inconclusive; some of their images were blurry, and so failed to resolve the matter definitively.
  • it was only natural for intelligent people who were free of the rule’s strictures to attempt a kind of holistic, systematic inquiry that was, in many ways, more demanding. It never occurred to them to ask if they might illuminate more collectively by thinking about less individually.
  • In the single-sphered, pre-scientific world, thinkers tended to inquire into everything at once. Often, they arrived at conclusions about nature that were fascinating, visionary, and wrong.

  • . The purpose of this review article is to summarize recent researches focusing on phantom limb in order to discuss its definition, mechanisms, and treatments.
  • The incidence of phantom limb pain has varied from 2% in earlier records to higher rates today. Initially, patients were less likely to mention pain symptoms than today which is a potential explanation for the discrepancy in incidence rates. However, Sherman et al.4 discuss that only 17% phantom limb complaints were initiated treated by physicians. Consequently, it is important to determine what constitutes phantom pain in order to provide efficacious care. Phantom pain is pain sensation to a limb, organ or other tissue after amputation and/or nerve injury.5 In podiatry, the predominant cause of phantom limb pain is after limb amputation due to diseased state presenting with an unsalvageable limb. Postoperative pain sensations from stump neuroma pain, prosthesis, fibrosis, and residual local tissue inflammation can be similar to phantom limb pain (PLP). Patients with PLP complain of various sensations including burning, stinging, aching, and piercing pain with changing warmth and cold sensation to the amputated area which waxes and wanes.6 Onset of symptoms may be elicited by environmental, emotional, or physical changes.
  • The human body encompasses various neurologic mechanisms allowing reception, transport, recognition, and response to numerous stimuli. Pain, temperature, crude touch, and pressure sensory information are carried to the central nervous system via the anterolateral system, with pain & temperature information transfer via lateral spinothalamic tracts to the parietal lobe. In detail, pain sensation from the lower extremity is transported from a peripheral receptor to a first degree pseudounipolar neurons in the dorsal root ganglion and decussate and ascend to the third-degree neurons within the thalamus.7 This sensory information will finally arrive at the primary sensory cortex in the postcentral gyrus of the parietal lobe which houses the sensory homunculus.8 It is unsurprising that with an amputation that such an intricate highway of information transport to and from the periphery may have the potential for problematic neurologic developments.

  • How does pain sensation, a protection mechanism for the human body, become chronic and unrelenting after limb loss? This is a question researchers still ask today with no concise conclusion. Phantom limb pain occurs more frequently in patients who also experience longer periods of stump pain and is more likely to subside as the stump pain subsides.9 Researchers have also found dorsal root ganglion cells change after a nerve is completely cut. The dorsal root ganglion cells become more active and sensitive to chemical and mechanical changes with potential for plasticity development at the dorsal horn and other areas.10 At the molecular level, increasing glutamate and NMDA (N-methyl d-aspartate) concentrations correlate to increased sensitivity which contributes to allodynia and hyperalgesia.11 Flor et al.12 further described the significance of maladaptive plasticity and the development of memory for pain and phantom limb pain. They correlated it to the loss of GABAergic inhibition and the development of glutamate induced long-term potentiation changes and structural changes like myelination and axonal sprouting.
  • Phantom limb pain in some patients may gradually disappear over the course of a few months to one year if not treated, but some patients suffer from phantom limb pain for decades. Treatments include pharmacotherapy, adjuvant therapy, and surgical intervention. There are a variety of medications to choose from, which includes tricyclic antidepressants, opioids, and NSAIDs, etc. Among these medications, Tricyclic antidepressant is one of the most common treatments. Studies have shown that Amitriptyline (a tricyclic antidepressant) has a good effect on relieving neuropathic pain.25
  • Phantom limb pain is very common in amputees. As a worldwide issue, it has been studied by a lot of researchers. Although phantom limb sensation has already been described and proposed by French military surgeon Ambroise Pare 500 years ago, there is still no detailed explanation of its mechanisms. Therefore, more research will be needed on the different types of mechanisms of phantom limb pain. Once researchers and physicians are able to identify the mechanism of phantom limb pain, mechanism-based treatment will be rapidly developed. As a result, more patients will be benefit from it in the long run.

What's behind the confidence of the incompetent? This suddenly popular psychological phenomenon. - The Washington Post - 1 views

  • To test Darwin’s theory, the researchers quizzed people on several topics, such as grammar, logical reasoning and humor. After each test, they asked the participants how they thought they did. Specifically, participants were asked how many of the other quiz-takers they beat.
  • Dunning was shocked by the results, even though it confirmed his hypothesis. Time after time, no matter the subject, the people who did poorly on the tests ranked their competence much higher. On average, test takers who scored as low as the 10th percentile ranked themselves near the 70th percentile. Those least likely to know what they were talking about believed they knew as much as the experts.
  • Dunning and Kruger’s results have been replicated in at least a dozen different domains: math skills, wine tasting, chess, medical knowledge among surgeons and firearm safety among hunters.

  • Dunning-Kruger “offers an explanation for a kind of hubris,” said Steven Sloman, a cognitive psychologist at Brown University. “The fact is, that’s Trump in a nutshell. He’s a man with zero political skill who has no idea he has zero political skill. And it’s given him extreme confidence.”
  • What happens when the incompetent are unwilling to admit they have shortcomings? Are they so confident in their own perceived knowledge that they will reject the very idea of improvement? Not surprisingly (though no less concerning), Dunning’s follow-up research shows the poorest performers are also the least likely to accept criticism or show interest in self improvement.
  • Someone who has very little knowledge in a subject claims to know a lot.
  • the Dunning-Kruger effect. It’s not a disease, syndrome or mental illness; it is present in everybody to some extent, and it’s been around as long as human cognition, though only recently has it been studied and documented in social psychology
  • “Obviously it has to do with Trump and the various treatments that people have given him,” Dunning said, “So yeah, a lot of it is political. People trying to understand the other side. We have a massive rise in partisanship and it’s become more vicious and extreme, so people are reaching for explanations."
  • Even though President Trump’s statements are rife with errors, falsehoods or inaccuracies, he expresses great confidence in his aptitude. He says he does not read extensively because he solves problems “with very little knowledge other than the knowledge I [already] had.” He has said in interviews he doesn’t read lengthy reports because “I already know exactly what it is.”
  • the Dunning-Kruger effect has become popular outside of the research world because it is a simple phenomenon that could apply to all of us
  • The ramifications of the Dunning-Kruger effect are usually harmless. If you’ve ever felt confident answering questions on an exam, only to have the teacher mark them incorrect, you have firsthand experience with Dunning-Kruger.

Understanding Science: An overview - 0 views

  • Science is, in one sense, our knowledge of all that — all the stuff that is in the universe
  • But just as importantly, science is also a reliable process by which we learn about all that stuff in the universe. However, science is different from many other ways of learning because of the way it is done. Science relies on testing ideas with evidence gathered from the natural world.
  • Science helps satisfy the natural curiosity with which we are all born: why is the sky blue, how did the leopard get its spots, what is a solar eclipse? With science, we can answer such questions without resorting to magical explanations.

  • Without science, the modern world would not be modern at all, and we still have much to learn.
  • does not deal with supernatural explanations.
  • it is a path to understanding.
  • all science relies on testing ideas by figuring out what expectations are generated by an idea and making observations to find out whether those expectations hold true.
  • Accepted scientific ideas are reliable because they have been subjected to rigorous testing,
  • It relies on a system of checks and balances, which helps ensure that science moves in the direction of greater accuracy and understanding. This system is facilitated by diversity within the scientific community, which offers a broad range of perspectives on scientific ideas.
