Anti-vaccine activists, 9/11 deniers, and Google's social search. - Slate Magazine - 1 views

  • democratization of information-gathering—when accompanied by smart institutional and technological arrangements—has been tremendously useful, giving us Wikipedia and Twitter. But it has also spawned thousands of sites that undermine scientific consensus, overturn well-established facts, and promote conspiracy theories
  • Meanwhile, the move toward social search may further insulate regular visitors to such sites; discovering even more links found by their equally paranoid friends will hardly enlighten them.
  • Initially, the Internet helped them find and recruit like-minded individuals and promote events and petitions favorable to their causes. However, as so much of our public life has shifted online, they have branched out into manipulating search engines, editing Wikipedia entries, harassing scientists who oppose whatever pet theory they happen to believe in, and amassing digitized scraps of "evidence" that they proudly present to potential recruits.

  • The Vaccine article contains a number of important insights. First, the anti-vaccination cohort likes to move the goal posts: As scientists debunked the link between autism and mercury (once present in some childhood inoculations but now found mainly in certain flu vaccines), most activists dropped their mercury theory and point instead to aluminum or said that kids received “too many too soon.”
  • Second, it isn't clear whether scientists can "discredit" the movement's false claims at all: Its members are skeptical of what scientists have to say—not least because they suspect hidden connections between academia and pharmaceutical companies that manufacture the vaccines.
  • mere exposure to the current state of the scientific consensus will not sway hard-core opponents of vaccination. They are too vested in upholding their contrarian theories; some have consulting and speaking gigs to lose while others simply enjoy a sense of belonging to a community, no matter how kooky
  • attempts to influence communities that embrace pseudoscience or conspiracy theories by having independent experts or, worse, government workers join them—the much-debated antidote of “cognitive infiltration” proposed by Cass Sunstein (who now heads the Office of Information and Regulatory Affairs in the White House)—w
  • perhaps, it's time to accept that many of these communities aren't going to lose core members regardless of how much science or evidence is poured on them. Instead, resources should go into thwarting their growth by targeting their potential—rather than existent—members.
  • Given that censorship of search engines is not an appealing or even particularly viable option, what can be done to ensure that users are made aware that all the pseudoscientific advice they are likely to encounter may not be backed by science?
  • One is to train our browsers to flag information that may be suspicious or disputed. Thus, every time a claim like "vaccination leads to autism" appears in our browser, that sentence woul
  • The second—and not necessarily mutually exclusive—option is to nudge search engines to take more responsibility for their index and exercise a heavier curatorial control in presenting search results for issues like "global warming" or "vaccination." Google already has a list of search queries that send most traffic to sites that trade in pseudoscience and conspiracy theories; why not treat them differently than normal queries? Thus, whenever users are presented with search results that are likely to send them to sites run by pseudoscientists or conspiracy theorists, Google may simply display a huge red banner asking users to exercise caution and check a previously generated list of authoritative resources before making up their minds.
  • In more than a dozen countries Google already does something similar for users who are searching for terms like "ways to die" or "suicidal thoughts" by placing a prominent red note urging them to call the National Suicide Prevention Hotline.

Coursekit Raises $5 Million to Reinvent the Classroom - NYTimes.com - 0 views

  • Coursekit is a new tool that lets teachers and educators create mini social networks around individual courses and lectures.
  • The goal of the service, said Joseph Cohen, its co-founder and chief executive, is to take some of the most successful elements of social networking — especially the fluid exchange of ideas that comes natural to online interactions — to revitalize the education experience. Students are already accustomed to interacting online and supplementing their daily lives with the Web and social media. Why should that stop when it comes to learning? “Our education experience is truly offline,” he said. “We want to build what Facebook has done for your personal life, but for your school.”
  • Using Coursekit’s software, teachers can upload homework assignments, answer questions, grade work and facilitate discussions with their students. In addition, students can use the software to chat with one another, collaborate on projects and share relevant materials with their classmates

Does Technology Affect Happiness? - NYTimes.com - 1 views

  • How is technology affecting their happiness and emotional development?
  • The answer, in the peer-reviewed study of the online habits of girls ages 8 to 12, is that those who say they spend considerable amounts of time using multimedia describe themselves in ways that suggest they are less happy and less socially comfortable than peers who say they spend less time on screens.
  • Among the crucial questions that the researchers were not able to answer is whether the heavy use of media was the cause for the relative unhappiness or whether girls who are less happy to begin with are drawn to heavy use of media, in effect retreating to a virtual world.

  • on a basic, even primitive level, girls need to experience the full pantheon of communication that comes from face-to-face contact, such as learning to read body language, and subtle facial and verbal cues.
  • The fact that the study was based on an online survey gave pause to some academics. While they said the paper raised good questions, they also expressed concern about giving it too much weight, given that the researchers were not able to follow up with the survey subjects to get important context, including their family circumstances, income or ethnicity.
  • The researchers found that the average amount of media use by the girls surveyed was 6.9 hours per day, a figure that included reading as well as screen time. The average amount of time spent in face-to-face social settings was 2.1 hours, a figure that did not include classroom time.
  • Ms. Gray said, she worries that her daughter, who is using Facebook more, is playing out her social life online sometimes without the benefits of the full emotional range that comes from face-to-face interaction.

The Folly of Fools - By Robert Trivers - Book Review - NYTimes.com - 0 views

  • Fooling others yields obvious benefits, but why do we so often fool ourselves? Trivers provides a couple of answers. First, believing that we’re smarter, sexier and more righteous than we really are — or than others consider us to be — can help us seduce and persuade others and even improve our health, via the placebo effect, for example. And the more we believe our own lies, the more sincerely, and hence effectively, we can lie to others.
  • One intriguing theme running through “The Folly of Fools” is that self-­deception can affect our susceptibility to disease, for ill or good.

What Happened Before the Big Bang? The New Philosophy of Cosmology - Ross Andersen - Te... - 1 views

  • This question of accounting for what we call the "big bang state" -- the search for a physical explanation of it -- is probably the most important question within the philosophy of cosmology, and there are a couple different lines of thought about it.
  • One that's becoming more and more prevalent in the physics community is the idea that the big bang state itself arose out of some previous condition, and that therefore there might be an explanation of it in terms of the previously existing dynamics by which it came about
  • The problem is that quantum mechanics was developed as a mathematical tool. Physicists understood how to use it as a tool for making predictions, but without an agreement or understanding about what it was telling us about the physical world. And that's very clear when you look at any of the foundational discussions. This is what Einstein was upset about; this is what Schrodinger was upset about. Quantum mechanics was merely a calculational technique that was not well understood as a physical theory. Bohr and Heisenberg tried to argue that asking for a clear physical theory was something you shouldn't do anymore. That it was something outmoded. And they were wrong, Bohr and Heisenberg were wrong about that. But the effect of it was to shut down perfectly legitimate physics questions within the physics community for about half a century. And now we're coming out of that

  • One common strategy for thinking about this is to suggest that what we used to call the whole universe is just a small part of everything there is, and that we live in a kind of bubble universe, a small region of something much larger
  • Newton realized there had to be some force holding the moon in its orbit around the earth, to keep it from wandering off, and he knew also there was a force that was pulling the apple down to the earth. And so what suddenly struck him was that those could be one and the same thing, the same force
  • That was a physical discovery, a physical discovery of momentous importance, as important as anything you could ever imagine because it knit together the terrestrial realm and the celestial realm into one common physical picture. It was also a philosophical discovery in the sense that philosophy is interested in the fundamental natures of things.
  • There are other ideas, for instance that maybe there might be special sorts of laws, or special sorts of explanatory principles, that would apply uniquely to the initial state of the universe.
  • The basic philosophical question, going back to Plato, is "What is x?" What is virtue? What is justice? What is matter? What is time? You can ask that about dark energy - what is it? And it's a perfectly good question.
  • right now there are just way too many freely adjustable parameters in physics. Everybody agrees about that. There seem to be many things we call constants of nature that you could imagine setting at different values, and most physicists think there shouldn't be that many, that many of them are related to one another. Physicists think that at the end of the day there should be one complete equation to describe all physics, because any two physical systems interact and physics has to tell them what to do. And physicists generally like to have only a few constants, or parameters of nature. This is what Einstein meant when he famously said he wanted to understand what kind of choices God had --using his metaphor-- how free his choices were in creating the universe, which is just asking how many freely adjustable parameters there are. Physicists tend to prefer theories that reduce that number
  • You have others saying that time is just an illusion, that there isn't really a direction of time, and so forth. I myself think that all of the reasons that lead people to say things like that have very little merit, and that people have just been misled, largely by mistaking the mathematics they use to describe reality for reality itself. If you think that mathematical objects are not in time, and mathematical objects don't change -- which is perfectly true -- and then you're always using mathematical objects to describe the world, you could easily fall into the idea that the world itself doesn't change, because your representations of it don't.
  • physicists for almost a hundred years have been dissuaded from trying to think about fundamental questions. I think most physicists would quite rightly say "I don't have the tools to answer a question like 'what is time?' - I have the tools to solve a differential equation." The asking of fundamental physical questions is just not part of the training of a physicist anymore.
  • The question remains as to how often, after life evolves, you'll have intelligent life capable of making technology. What people haven't seemed to notice is that on earth, of all the billions of species that have evolved, only one has developed intelligence to the level of producing technology. Which means that kind of intelligence is really not very useful. It's not actually, in the general case, of much evolutionary value. We tend to think, because we love to think of ourselves, human beings, as the top of the evolutionary ladder, that the intelligence we have, that makes us human beings, is the thing that all of evolution is striving toward. But what we know is that that's not true. Obviously it doesn't matter that much if you're a beetle, that you be really smart. If it were, evolution would have produced much more intelligent beetles. We have no empirical data to suggest that there's a high probability that evolution on another planet would lead to technological intelligence.

SOPA Boycotts and the False Ideals of the Web - NYTimes.com - 1 views

  • Those rare tech companies that have come out in support of SOPA are not merely criticized but barred from industry events and subject to boycotts. We, the keepers of the flame of free speech, are banishing people for their speech. The result is a chilling atmosphere, with people afraid to speak their minds.
  • Our melodrama is driven by a vision of an open Internet that has already been distorted, though not by the old industries that fear piracy. For instance, until a year ago, I enjoyed a certain kind of user-generated content very much: I participated in forums in which musicians talked about musical instruments.
  • proprietary social networking — is ending my freedom to participate in the forums I used to love, at least on terms I accept. Like many other forms of contact, the musical conversations are moving into private sites, particularly Facebook. To continue to participate, I’d have to accept Facebook’s philosophy, under which it analyzes me, and is searching for new ways to charge third parties for the use of that analysis.

  • You might object that it’s all based on individual choice. That argument ignores the consequences of networks, and the way they function. After a certain point choice is reduced.
  • What if ordinary users routinely earned micropayments for their contributions? If all content were valued instead of only mogul content, perhaps an information economy would elevate success for all. But under the current terms of debate that idea can barely be whispered.
  • Once networks are established, it is hard to reduce their power. Google’s advertisers, for instance, know what will happen if they move away. The next-highest bidder for each position in Google’s auction-based model for selling ads will inherit that position if the top bidder goes elsewhere. So Google’s advertisers tend to stay put because the consequences of leaving are obvious to them
  • The obvious strategy in the fight for a piece of the advertising pie is to close off substantial parts of the Internet so Google doesn’t see it all anymore. That’s how Facebook hopes to make money, by sealing off a huge amount of user-generated information into a separate, non-Google world.
  • it’s not Facebook’s fault! We, the idealists, insisted that information be able to flow freely online, which meant that services relating to information, instead of the information itself, would be the main profit centers. Some businesses do sell content, but that doesn’t address the business side of everyday user-generated content. The adulation of “free content” inevitably meant that “advertising” would become the biggest business in the open part of the information economy
  • We in Silicon Valley undermined copyright to make commerce become more about services instead of content — more about our code instead of their files. The inevitable endgame was always that we would lose control of our own personal content, our own files.

What Is College For? - NYTimes.com - 0 views

  • 74 percent of graduates from four-year colleges say that their education was “very useful in helping them grow intellectually.”
  • When, as is often the case in business education and teacher training, practical skills far outweigh theoretical understanding, we are moving beyond the intellectual culture that defines higher education
  • This lack of academic engagement is real, even among schools with the best students and the best teachers, and it increases dramatically as the quality of the school decreases.  But it results from a basic misunderstanding — by both students and teachers — of what colleges are for.
  • ...5 more annotations...
  • First of all, they are not simply for the education of students.  This is an essential function, but the raison d’être of a college is to nourish a world of intellectual culture; that is, a world of ideas, dedicated to what we can know scientifically, understand humanistically, or express artistically.  In our society, this world is mainly populated by members of college faculties: scientists, humanists, social scientists (who straddle the humanities and the sciences properly speaking), and those who study the fine arts. Law, medicine and engineering are included to the extent that they are still understood as “learned professions,” deploying practical skills that are nonetheless deeply rooted in scientific knowledge or humanistic understanding
  • there are serious concerns about the quality of this experience.  In particular, the university curriculum leaves students disengaged from the material they are supposed to be learning.  They see most of their courses as intrinsically “boring,” of value only if they provide training relevant to future employment or if the teacher has a pleasing (amusing, exciting, “relevant”) way of presenting the material. As a result, students spend only as much time as they need to get what they see as acceptable grades (on average, about 12 to 14 hour a week for all courses combined).  Professors have ceased to expect genuine engagement from students and often give good grades (B or better) to work that is at best minimally adequate.
  • Our support for higher education makes sense only if we regard this intellectual culture as essential to our society
  • This has important consequences for how we regard what goes on in college classrooms.  Teachers need to see themselves as, first of all, intellectuals, dedicated to understanding poetry, history, human psychology, physics, biology — or whatever is the focus of their discipline.  But they also need to realize that this dedication expresses not just their idiosyncratic interest in certain questions but a conviction that those questions have general human significance, even apart from immediately practical applications.  This is why a discipline requires not just research but also teaching
  • Students, in turn, need to recognize that their college education is above all a matter of opening themselves up to new dimensions of knowledge and understanding.  Teaching is not a matter of (as we too often say) “making a subject (poetry, physics, philosophy) interesting” to students but of students coming to see how such subjects are intrinsically interesting.  It is more a matter of students moving beyond their interests than of teachers fitting their subjects to interests that students already have.   Good teaching does not make a course’s subject more interesting; it gives the students more interests — and so makes them more interesting.

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

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

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

Who You Are on Facebook Is Probably Pretty Much Who You Are - Megan Garber - Technology... - 3 views

  • , Dr. Sam Gosling and his colleagues first asked participants to complete the Ten Item Personality Inventory, which asked them to assess the extent to which factors like extroversion, anxiety, and calmness applied to them. The researchers used the results of those surveys to assess the participants according to the big five personality traits: openness, conscientiousness, extroversion, agreeableness, and neuroticism. They then compared those findings to the information represented in participants' Facebook profiles
  • What the researchers found was a big correlation between the personalities represented on Facebook and the personalities suggested by the test. The extroverts had more Facebook friends than the introverts; those who were open to new people and experiences in the physical world replicated that tendency in the digital. "The study determined that online social networks are not an escape from reality," RWW's Alicia Eler put it, "but rather a microcosm of peoples' larger social worlds and an extension of offline behaviors."

The Greatness of Ron Paul - Robert Wright - Politics - The Atlantic - 0 views

  • Paul is making one contribution to the foreign policy debate that could have enduring value. It doesn't lie in the substance of his foreign policy views (which I'm largely but not wholly in sympathy with) but in the way he explains them. Paul routinely performs a simple thought experiment: He tries to imagine how the world looks to people other than Americans.
  • A favorite Paul pedagogical device is to analogize foreign situations to American ones
  • I've long thought that the biggest single problem in the world is the failure of "moral imagination"--the inability or unwillingness of people to see things from the perspective of people in circumstances different from their own. Especially incendiary is the failure to extend moral imagination across national, religious, or ethnic borders.

How Does the Brain Perceive Art? | Wired Science | Wired.com - 2 views

  • our aesthetic judgements are really complicated. While Rembrandt was an astonishingly talented artist, our response to his art is conditioned by all sorts of variables that have nothing to do with oil paint. Many of these variables are capable of distorting our perceptions, so that we imagine differences that don’t actually exist; the verdict of art history warps what we see. The power of a Rembrandt, in other words, is inseparable from the fact that it’s a Rembrandt. The man is a potent brand.
  • Our findings support the idea that when people make aesthetic judgements, they are subject to a variety of influences. Not all of these are immediately articulated. Indeed, some may be inaccessible to direct introspection but their presence might be revealed by brain imaging. It suggests that different regions of the brain interact together when a complex judgment is formed, rather than there being a single area of the brain that deals with aesthetic judgements.
  • We want to believe that pleasure is simple, that our delight in a fine painting or bottle of wine is due entirely to the thing itself. But that’s not the way reality works. Whenever we experience anything, that experience is shaped by factors and beliefs that are not visible on the canvas or present in the glass. Even the most exquisite works in the world — and what is more exceptional than a Rembrandt portrait? — still require a little mental help. We only see the beauty because we are looking for it.

Is Confidence in Science as a Source of Progress Based on Faith or Fact? - NYTimes.com - 3 views

  • There’s been a range of interesting reactions to my piece on Pete Seeger’s question about whether confidence in science as a source of human progress is underpinned by fact or faith.
  • the discussion was not about confidence in science as an enterprise, but confidence that benefits would always accrue to society from applications of scientific knowledge
  • Theologically speaking, science constantly reminds us of the sense in which we are nearly – but clearly not quite – gods. Perhaps the trickiest value issues surrounding science are hidden behind the seemingly innocent metaphors of ‘getting into the mind of God’ (physics) and ‘playing God’ (biomedicine). Notwithstanding scientists’ own disclaimers, as a matter of fact science has done as well as it has because scientists have adopted a ‘godlike’ attitude toward nature. We have allowed ourselves to imagine and intervene in things at very high levels of abstraction and in ways that can only be justified in terms of the power unleashed by the resulting systematic view of things. The costs incurred have included devaluing our most immediate experiences of nature and subjecting things to quite artificial conditions in order to extract knowledge.

  • For Francis Bacon and the other early Scientific Revolutionaries, this was a fair price to pay for doing divine work – God, after all, was thought to be himself transcendent and perhaps even alienated from nature. But without this theistic assumption, it becomes difficult to justify the unfettered pursuit of science, once both the costs and benefits are each given their due. Of course, we could simply say that science is what turns humans into gods. For all its hubris, this response would at least possess the virtues of candor and consistency. As it stands, scientists shy away from any such strong self-understandings, preferring to hide behind more passive accounts of their activities – e.g. they ‘describe’ rather than generate phenomena, they ‘explain’ rather than justify nature, etc. Lost in this secular translation of an originally sacred mission is the scientist’s sense of personal responsibility qua scientist.

Occupy Language? - NYTimes.com - 0 views

  • It has already succeeded in shifting the terms of the debate, taking phrases like “debt-ceiling” and “budget crisis” out of the limelight and putting terms like “inequality” and “greed” squarely in the center. This discursive shift has made it more difficult for Washington to obscure the spurious reasons for the financial meltdown and the unequal outcomes it has exposed
  • In early September, “occupy” signaled on-going military incursions. Now it signifies progressive political protest. It’s no longer primarily about force of military power; instead it signifies standing up to injustice, inequality and abuse of power. It’s no longer about simply occupying a space; it’s about transforming that space.
  • This is a far cry from some of its earlier meanings. In fact, The Oxford English Dictionary tells us that “occupy” once meant “to have sexual intercourse with.”

  • Occupy Language might also support the campaign to stop the media from using the word “illegal” to refer to “undocumented” immigrants. From the campaign’s perspective, only inanimate objects and actions are labeled illegal in English; therefore the use of “illegals” to refer to human beings is dehumanizing.
  • the F.B.I.’s annual Hate Crime Statistics show that Latinos comprised two thirds of the victims of ethnically motivated hate crimes in 2010. When someone is repeatedly described as something, language has quietly paved the way for violent action.
  • By occupying language, we can expose how educational, political, and social institutions use language to further marginalize oppressed groups; resist colonizing language practices that elevate certain languages over others; resist attempts to define people with terms rooted in negative stereotypes; and begin to reshape the public discourse about our communities, and about the central role of language in racism and discrimination.

  • I think originality is a word of praise for things that have been expressed in a marvelous way and that make points of origin for any particular element beside the point.  When you read Saul Bellow or listen to Bob Dylan sing, you can have someone point to various cribbings and it won’t matter, because something has been arrived at which subsumes and incorporates and transcends these matters.  In that way, sourcing and originality are two sides of the same coin, they’re a nested partnership.  I don’t think originality has any value as a description of process.  In that regard it’s as meaningless a process word as beauty is.  No artist says, “Let me sit down and do some beauty now.”

Book Review: Models Behaving Badly - WSJ.com - 1 views

  • Mr. Derman is perhaps a bit too harsh when he describes EMM—the so-called Efficient Market Model. EMM does not, as he claims, imply that prices are always correct and that price always equals value. Prices are always wrong. What EMM says is that we can never be sure if prices are too high or too low.
  • The Efficient Market Model does not suggest that any particular model of valuation—such as the Capital Asset Pricing Model—fully accounts for risk and uncertainty or that we should rely on it to predict security returns. EMM does not, as Mr. Derman says, "stubbornly assume that all uncertainty about the future is quantifiable." The basic lesson of EMM is that it is very difficult—well nigh impossible—to beat the market consistently.
  • Mr. Derman gives an eloquent description of James Clerk Maxwell's electromagnetic theory in a chapter titled "The Sublime." He writes: "The electromagnetic field is not like Maxwell's equations; it is Maxwell's equations."
  • ...4 more annotations...
  • He sums up his key points about how to keep models from going bad by quoting excerpts from his "Financial Modeler's Manifesto" (written with Paul Wilmott), a paper he published a couple of years ago. Among its admonitions: "I will always look over my shoulder and never forget that the model is not the world"; "I will not be overly impressed with mathematics"; "I will never sacrifice reality for elegance"; "I will not give the people who use my models false comfort about their accuracy"; "I understand that my work may have enormous effects on society and the economy, many beyond my apprehension."
  • As the collapse of the subprime collateralized debt market in 2008 made clear, it is a terrible mistake to put too much faith in models purporting to value financial instruments. "In crises," Mr. Derman writes, "the behavior of people changes and normal models fail. While quantum electrodynamics is a genuine theory of all reality, financial models are only mediocre metaphors for a part of it."
  • Although financial models employ the mathematics and style of physics, they are fundamentally different from the models that science produces. Physical models can provide an accurate description of reality. Financial models, despite their mathematical sophistication, can at best provide a vast oversimplification of reality. In the universe of finance, the behavior of individuals determines value—and, as he says, "people change their minds."
  • Bringing ethics into his analysis, Mr. Derman has no patience for coddling the folly of individuals and institutions who over-rely on faulty models and then seek to escape the consequences. He laments the aftermath of the 2008 financial meltdown, when banks rebounded "to record profits and bonuses" thanks to taxpayer bailouts. If you want to benefit from the seven fat years, he writes, "you must suffer the seven lean years too, even the catastrophically lean ones. We need free markets, but we need them to be principled."

Jonathan Haidt and the Moral Matrix: Breaking Out of Our Righteous Minds | Guest Blog, ... - 2 views

  • it helped shift moral psychology away from rationalist models that dominated in the 1980s and 1990s. In its place Haidt offered an understanding of morality from an intuitive and automatic level. As Haidt says on his website, “we are just not very good at thinking open-mindedly about moral issues, so rationalist models end up being poor descriptions of actual moral psychology.”
  • “the mind is divided into parts that sometimes conflict. Like a rider on the back of an elephant, the conscious, reasoning part of the mind has only limited control of what the elephant does.”
  • In the last few decades psychology began to understand the unconscious mind not as dark and suppressed as Freud did, but as intuitive, highly intelligent and necessary for good conscious reasoning. “Elephants,” he reminded me, “are really smart, much smarter than horses.”
  • we are 90 percent chimp 10 percent bee. That is to say, though we are inherently selfish, human nature is also about being what he terms “groupish.” He explained to me like this:
  • they developed the idea that humans possess six universal moral modules, or moral “foundations,” that get built upon to varying degrees across culture and time. They are: Care/harm, Fairness/cheating, Loyalty/betrayal, Authority/subversion, Sanctity/degradation, and Liberty/oppression. Haidt describes these six modules like a “tongue with six taste receptors.” “In this analogy,” he explains in the book, “the moral matrix of a culture is something like its cuisine: it’s a cultural construction, influenced by accidents of environment and history, but it’s not so flexible that anything goes. You can’t have a cuisine based on grass and tree bark, or even one based primarily on bitter tastes. Cuisines vary, but they all must please tongues equipped with the same five taste receptors. Moral matrices vary, but they all must please righteous minds equipped with the same six social receptors.”
  • The questionnaire eventually manifested itself into the website www.YourMorals.org, and it has since gathered over two hundred thousand data points. Here is what they found:
  • This is the crux of the disagreement between liberals and conservatives. As the graph illustrates, liberals value Care and Fairness much more than the other three moral foundations whereas conservative endorse all five more or less equally. This shouldn’t sound too surprising, liberals tend to value universal rights and reject the idea of the United States being superior while conservatives tend to be less concerned about the latest United Nation declaration and more partial to the United States as a superior nation.
  • Haidt began reading political psychology. Karen Stenner’s The Authoritarian Dynamic, “conveyed some key insights about protecting the group that were particularly insightful,” he said. The work of the French sociologist Emile Durkheim was also vital. In contrast to John Stuart Mill, a Durkheimian society, as Haidt explains in an essay for edge.org, “would value self-control over self-expression, duty over rights, and loyalty to one’s groups over concerns for out-groups.”
  • He was motivated to write The Righteous Mind after Kerry lost the 2004 election: “I thought he did a terrible job of making moral appeals so I began thinking about how I could apply moral psychology to understand political divisions. I started studying the politics of culture and realized how liberals and conservatives lived in their own closed worlds.” Each of these worlds, as Haidt explains in the book, “provides a complete, unified, and emotionally compelling worldview, easily justified by observable evidence and nearly impregnable to attack by arguments from outsiders.” He describes them as “moral matrices,” and thinks that moral psychology can help him understand them.
  • “When I say that human nature is selfish, I mean that our minds contain a variety of mental mechanisms that make us adept at promoting our own interests, in competition with our peers. When I say that human nature is also groupish, I mean that our minds contain a variety of mental mechanisms that make us adept at promoting our group’s interests, in competition with other groups. We are not saints, but we are sometimes good team players.” This is what people who had studied morality had not realized, “that we evolved not just so I can treat you well or compete with you, but at the same time we can compete with them.”
  • At first, Haidt reminds us that we are all trapped in a moral matrix where
  • our “elephants” only look for what confirms its moral intuitions while our “riders” play the role of the lawyer; we team up with people who share similar matrices and become close-minded; and we forget that morality is diverse. But on the other hand, Haidt is offering us a choice: take the blue pill and remain happily delusional about your worldview, or take the red pill, and, as he said in his 2008 TED talk, “learn some moral psychology and step outside your moral matrix.”
  • The great Asian religions, Haidt reminded the crowd at TED, swallowed their pride and took the red pill millennia ago. And by stepping out of their moral matrices they realized that societies flourish when they value all of the moral foundations to some degree. This is why Ying and Yang aren’t enemies, “they are both necessary, like night and day, for the functioning of the world.” Or, similarly, why the two of the high Gods in Hinduism, Vishnu the preserver (who stands for conservative principles) and Shiva the destroyer (who stands for liberal principles) work together.
