Screening Health Care Diagnosis Test Measurement Validity

shared by Weiye Loh on 14 Mar 11 - No Cached
  • The truth is not all screening tests are equal, and more importantly, even when a screening test is accurate (yes, I chose to use this term because I am lazy) and we are able "determine the health condition of an individual", it did not necessarily mean that it was cost-effective to screen the population at large, or indeed a specific patient. Unfortunately, if someone was in a position that "the costs of these tests are a big burden" to him or her, an accurate diagnosis may just be the beginning of more financial burden...
  • But the cost-effectiveness of screening tests are really quite a technical issue that we cannot expect laymen (or even all doctors) to understand - that's not what bothered me about this letter. What bothered me was how a layman can think that a bunch of doctors and statisticians sitting in MOH can be blind to the benefits of "all cancer screenings as well as all tests to detect heart disease", which are so obvious to him.

Data Interpretation Statistics Cost Benefits Harm Cancer Screening Health

  • The USPSTF recently issued an even sharper warning about the prostate-specific antigen test for prostate cancer, after concluding that the test’s harms outweigh its benefits. Chest X-rays for lung cancer and Pap tests for cervical cancer have received similar, albeit less definitive, criticism.CommentsView/Create comment on this paragraphThe next step in the reevaluation of cancer screening was taken last year, when researchers at the Dartmouth Institute for Health Policy announced that the costs of screening for breast cancer were often minimized, and that the benefits were much exaggerated. Indeed, even a mammogram (almost 40 million are given annually in the US) that detects a cancer does not necessarily save a life.CommentsView/Create comment on this paragraphThe Dartmouth researchers found that, of the estimated 138,000 breast cancers detected annually in the US, the test did not help 120,000-134,000 of the afflicted women. The cancers either were growing so slowly that they did not pose a problem, or they would have been treated successfully if discovered clinically later (or they were so aggressive that little could be done).

Data Statistics

  • In the realm of public policy, we live in an age of numbers.
  • do wehold an outsize belief in our ability to gauge complex phenomena, measure outcomes and come up with compelling numerical evidence? A well-known quotation usually attributed to Einstein is “Not everything that can be counted counts, and not everything that counts can be counted.” I’d amend it to a less eloquent, more prosaic statement: Unless we know how things are counted, we don’t know if it’s wise to count on the numbers.
  • The problem isn’t with statistical tests themselves but with what we do before and after we run them.
  • ...9 more annotations...
  • First, we count if we can, but counting depends a great deal on previous assumptions about categorization. Consider, for example, the number of homeless people in Philadelphia, or the number of battered women in Atlanta, or the number of suicides in Denver. Is someone homeless if he’s unemployed and living with his brother’s family temporarily? Do we require that a women self-identify as battered to count her as such? If a person starts drinking day in and day out after a cancer diagnosis and dies from acute cirrhosis, did he kill himself? The answers to such questions significantly affect the count.
  • Second, after we’ve gathered some numbers relating to a phenomenon, we must reasonably aggregate them into some sort of recommendation or ranking. This is not easy. By appropriate choices of criteria, measurement protocols and weights, almost any desired outcome can be reached.
  • Are there good reasons the authors picked the criteria they did? Why did they weigh the criteria in the way they did?
  • Since the answer to the last question is usually yes, the problem of reasonable aggregation is no idle matter.
  • These two basic procedures — counting and aggregating — have important implications for public policy. Consider the plan to evaluate the progress of New York City public schools inaugurated by the city a few years ago. While several criteria were used, much of a school’s grade was determined by whether students’ performance on standardized state tests showed annual improvement. This approach risked putting too much weight on essentially random fluctuations and induced schools to focus primarily on the topics on the tests. It also meant that the better schools could receive mediocre grades becausethey were already performing well and had little room for improvement. Conversely, poor schools could receive high grades by improving just a bit.
  • Medical researchers face similar problems when it comes to measuring effectiveness.
  • Suppose that whenever people contract the disease, they always get it in their mid-60s and live to the age of 75. In the first region, an early screening program detects such people in their 60s. Because these people live to age 75, the five-year survival rate is 100 percent. People in the second region are not screened and thus do not receive their diagnoses until symptoms develop in their early 70s, but they, too, die at 75, so their five-year survival rate is 0 percent. The laissez-faire approach thus yields the same results as the universal screening program, yet if five-year survival were the criterion for effectiveness, universal screening would be deemed the best practice.
  • Because so many criteria can be used to assess effectiveness — median or mean survival times, side effects, quality of life and the like — there is a case to be made against mandating that doctors follow what seems at any given time to be the best practice. Perhaps, as some have suggested, we should merely nudge them with gentle incentives. A comparable tentativeness may be appropriate when devising criteria for effective schools.
  • Arrow’s Theorem, a famous result in mathematical economics, essentially states that no voting system satisfying certain minimal conditions can be guaranteed to always yield a fair or reasonable aggregation of the voters’ rankings of several candidates. A squishier analogue for the field of social measurement would say something like this: No method of measuring a societal phenomenon satisfying certain minimal conditions exists that can’t be second-guessed, deconstructed, cheated, rejected or replaced. This doesn’t mean we shouldn’t be counting — but it does mean we should do so with as much care and wisdom as we can muster.

Greenhoues Gases Green Energy Nuclear Risk

shared by Weiye Loh on 16 Mar 11 - No Cached
  • The German government announced today that it will shut down seven of the country's seventeen nuclear power plants for an indefinite period, a decision taken in response to widespread protests and a German public increasingly fearful of nuclear power after a nuclear emergency in Japan. The decision places a moratorium on a law that would extend the lifespan of these plants, and is uncharacteristic of Angela Merkel, whose government previously overturned its predecessor's decision to phase nuclear out of Germany's energy supply.
  • The seven plants, each built before 1980, represent 30% of Germany's nuclear electricity generation and 24% of its gross installed nuclear capacity. Shutting down these plants, or even just placing an indefinite hold on their operation, would be a major loss of zero-emissions generation capacity for Germany. The country currently relies on nuclear power from its seventeen nuclear power plants for about a quarter of its electricity supply.
  • The long-term closure of these plants would therefore seriously challenge Germany's carbon emissions efforts, as they try to meet the goal of 40% reduction below 1990 carbon emissions rates by 2020.
  • ...4 more annotations...
  • if lost generation were made up for entirely by coal-fired plants, carbon emissions would increase annually by as much as 33 million tons. This would represent an overall 4% annual increase in carbon emissions for the country and an 8% increase in carbon emissions for the power sector alone.
  • The moratorium could cause a spike in CO2 emissions as Germany turns to its other, more carbon-intensive sources to supply its energy demand. Already, the country has been engaged in a "dash for coal", building dozens of new coal plants in response to the perverse incentives and intense lobbying from the coal industries made possible by the European Emissions Trading Scheme. (As previously reported by Breakthrough Europe).
  • Alternatively, should the country try to replace lost generation entirely with power from renewables, it would need to more than double generation of renewable energy, from where it currently stands at 97 billion kWh to about 237 billion kWh. As part of the country's low-carbon strategy, Germany has planned to deploy at least 20% renewable energy sources by 2020. If the nation now chooses to meet this goal by displacing nuclear plants, 2020 emissions levels would be higher than had the country otherwise phased out its carbon-intensive coal or natural gas plants.
  • *Carbon emissions factors used are those estimated by the World Bank in 2009 for new coal-fired power plants (0.795 t C02/MWh) and new gas-fired power plants (0.398 t C02/MWh) **Data from Carbon Monitoring For Action, European Nuclear Society Data, and US Energy Information Administration
  • Weiye Loh on 16 Mar 11
     
    Carbon dioxide emissions in Germany may increase by 4 percent annually in response to a moratorium on seven of the country's oldest nuclear power plants, as power generation is shifted from nuclear power, a zero carbon source, to the other carbon-intensive energy sources that currently make up the country's energy supply.

shared by Weiye Loh on 14 Apr 11 - No Cached
  • The INES scale is an internationally agreed-upon standard. Signatory nations are themselves responsible for interpreting the scale and assigning numbers to their own incidents. There is not a single international body that does this. Indeed, from the INES web site: What the Scale is Not For It is not appropriate to use INES to compare safety performance between facilities, organizations or countries. The statistically small numbers of events at Level 2 and above and the differences between countries for reporting more minor events to the public make it inappropriate to draw international comparisons.
  • the INES number is not a “threat level”. It’s a rough assessment of the scale of a mess that has been created. It does not portend coming danger, it characterizes an incident.
  • Nuclear incident severity levels. Click on it to see it in full readable size.
  • ...3 more annotations...
  • Within Japan, it’s the NSC (Nuclear Safety Commission) that has responsibility for classifying its incidents. When they say Fukushima is a 7, it doesn’t necessarily mean the same thing as what the USSR considered to be a 7 in 1986. Why not? Because there are many different aspects to a nuclear incident. There are health effects, potential health effects, environmental effects, measurements of radiation released, and so on.
  • The scale boils all these factors down to a single number, which to me, is a misguided effort: 0 – No safety significance 1 – Anomaly 2 – Incident 3 – Serious incident 4 – Accident with local consequences 5 – Accident with wider consequences 6 – Serious accident 7 – Major accident I certainly agree that Fukushima is a 7, a major accident, considering its type of reactor. Chernobyl was a Generation 0 atomic pile, not really what you’d call a nuclear reactor, and I’m surprised it didn’t blow up half the continent.  For a proper nuclear reactor, I think Fukushima is about as bad as things can get.
  • But notice, it does not fulfill some of the qualifications of a 7, or even of a 4. For example, people start dying from radiation as early as 4 on the scale. Nobody has died from radiation at Fukushima (three were killed by the tsunami), and nobody was hurt at all at Three Mile Island which was a 5. The grimmest rational estimates of Chernobyl put its eventual death toll from cancer at 4,000. But it does fulfill the other qualifications of a 7; notably: Major release of radioactive material with widespread health and environmental effects requiring implementation of planned and extended countermeasures.

  • Further, grumblings on Facebook accounts are hardly ‘anonymous’. Lastly, how anonymous can bloggers be, when every now and then a racist blogger gets arrested by the state? Think about it. These sorts of cases prove that the state does screen, survey and monitor the online community, and as all of us know there are many vehement anti-PAP comments and articles, much of which are outright slander and defamation.
  • Yet at the end of the day, it is the racist blogger, not the anti-government or anti-PAP blogger that gets arrested. The Singaporean model is a much more complex and sophisticated phenomenon than this Guardian writer gives it credit.
  • Why did this Guardian writer, anyway, pander to a favourite Western stereotype of that “far-off Asian undemocratic, repressive regime”? Is she really in Singapore as the Guardian claims? (“Kate Hodal in Singapore” is written at the top) Can the Guardian be anymore predictable and trite?

  • Can any Singaporean honestly say the she/he can conceive of a fellow Singaporean setting himself or herself on fire along Orchard Road or Shenton Way, as a result of desperate economic pressures or financial constraints? Can we even fathom the social and economic pressures that mobilized a whole people to protest and overthrow a corrupt, US-backed regime? (that is, not during elections time) Singapore has real problems, the People’s Action Party has its real problems, and there is indeed much room for improvement. Yet such irresponsible reporting by one of the esteemed newspapers from the UK is utterly disappointing, not constructive in the least sense, and utterly misrepresents our political situation (and may potentially provoke more irrationality in our society, leading people to ‘believe’ their affinity with their Arab peers which leads to more radicalism).

Books Education Recycling ebooks

shared by Weiye Loh on 02 Jun 12 - No Cached
  • As an author, I’ve seen how the sales histories of textbooks work. Typically they have a big spike of sales for the first 1-2 years after they are introduced, and that’s when most the new copies are sold and most of the publisher’s money is made. But by year 3  (and sometimes sooner), the sales plunge and within another year or two, the sales are miniscule. The publishers have only a few options in a situation like this. One option: they can price the book so that the first two years’ worth of sales will pay their costs back before the used copies wipe out their market, which is the major reason new copies cost so much. Another option (especially with high-volume introductory textbooks) is to revise it within 2-3 years after the previous edition, so the new edition will drive all the used copies off the shelves for another two years or so. This is also a common strategy. For my most popular books, the publisher expected me to be working on a new edition almost as soon as the previous edition came out, and 2-3 years later, the new edition (with a distinctive new cover, and sometimes with significant new content as well) starts the sales curve cycle all over again. One of my books is in its eighth edition, but there are introductory textbooks that are in the 15th or 20th edition.
  • For over 20 years now, I’ve heard all sorts of prophets saying that paper textbooks are dead, and predicting that all textbooks would be electronic within a few years. Year after year, I  hear this prediction—and paper textbooks continue to sell just fine, thank you.  Certainly, electronic editions of mass market best-sellers, novels and mysteries (usually cheaply produced with few illustrations) seem to do fine as Kindle editions or eBooks, and that market is well established. But electronic textbooks have never taken off, at least in science textbooks, despite numerous attempts to make them work. Watching students study, I have a few thoughts as to why this is: Students seem to feel that they haven’t “studied” unless they’ve covered their textbook with yellow highlighter markings. Although there are electronic equivalents of the highlighter marker pen, most of today’s students seem to prefer physically marking on a real paper book. Textbooks (especially science books) are heavy with color photographs and other images that don’t often look good on a tiny screen, don’t print out on ordinary paper well, but raise the price of the book. Even an eBook is going to be a lot more expensive with lots of images compared to a mass-market book with no art whatsoever. I’ve watched my students study, and they like the flexibility of being able to use their book just about anywhere—in bright light outdoors away from a power supply especially. Although eBooks are getting better, most still have screens that are hard to read in bright light, and eventually their battery will run out, whether you’re near a power supply or not. Finally, if  you drop your eBook or get it wet, you have a disaster. A textbook won’t even be dented by hard usage, and unless it’s totally soaked and cannot be dried, it does a lot better when wet than any electronic book.
  • A recent study found that digital textbooks were no panacea after all. Only one-third of the students said they were comfortable reading e-textbooks, and three-fourths preferred a paper textbook to an e-textbook if the costs were equal. And the costs have hidden jokers in the deck: e-textbooks may seem cheaper, but they tend to have built-in expiration dates and cannot be resold, so they may be priced below paper textbooks but end up costing about the same. E-textbooks are not that much cheaper for publishers, either, since the writing, editing, art manuscript, promotion, etc., all cost the publisher the same whether the final book is in paper or electronic. The only cost difference is printing and binding and shipping and storage vs. creating the electronic version.
  • Weiye Loh on 02 Jun 12
     
    But in the 1980s and 1990s, the market changed drastically with the expansion of used book recyclers. They set up shop at the bookstore door near the end of the semester and bought students' new copies for pennies on the dollar. They would show up in my office uninvited and ask if I want to sell any of the free adopter's copies that I get from publishers trying to entice me. If you walk through any campus bookstore, nearly all the new copies have been replaced by used copies, usually very tattered and with broken spines. The students naturally gravitate to the cheaper used books (and some prefer them because they like it if a previous owner has highlighted the important stuff). In many bookstores, there are no new copies at all, or just a few that go unsold. What these bargain hunters don't realize is that every used copy purchased means a new copy unsold. Used copies pay nothing to the publisher (or the author, either), so to recoup their costs, publishers must price their new copies to offset the loss of sales by used copies. And so the vicious circle begins-publisher raises the price on the book again, more students buy used copies, so a new copy keeps climbing in price.

Libel Slander Law New Media Skepticism Science Communication

shared by Weiye Loh on 22 Feb 11 - No Cached
  • Skeptics may by now be very familiar with recent attempts in Canada to ban wifi from public schools and libraries.  In short: there is no valid scientific reason to be worried about wifi.  It has also been revealed that the chief scientists pushing the wifi bans have been relying on poor data and even poorer studies.  By far the vast majority of scientific data that currently exists supports the conclusion that wifi and cell phone signals are perfectly safe.
  • So I wrote about that particular topic in the summer.  It got some decent coverage, but the fear mongering continued. I wrote another piece after I did a little digging into one of the main players behind this, one Rodney Palmer, and I discovered some decidedly pseudo-scientific tendencies in his past, as well as some undisclosed collusion.
  • One night I came home after a long day at work, a long commute, and a phone call that a beloved family pet was dying, and will soon be in significant pain.  That is the state I was in when I read the news about Palmer and Parliamentary committee.
  • ...18 more annotations...
  • That’s when I wrote my last significant piece for Skeptic North.  Titled, “Rodney Palmer: When Pseudoscience and Narcissism Collide,” it was a fiery take-down of every claim I heard Palmer speak before the committee, as well as reiterating some of his undisclosed collusion, unethical media tactics, and some reasons why he should not be considered an expert.
  • This time, the article got a lot more reader eyeballs than anything I had ever written for this blog (or my own) and it also caught the attention of someone on a school board which was poised to vote on wifi.  In these regards: Mission very accomplished.  I finally thought that I might be able to see some people in the media start to look at Palmer’s claims with a more critical eye than they had been previously, and I was flattered at the mountain of kind words, re-tweets, reddit comments and Facebook “likes.”
  • The comments section was mostly supportive of my article, and they were one of the few things that kept me from hiding in a hole for six weeks.  There were a few comments in opposition to what I wrote, some sensible, most incoherent rambling (one commenter, when asked for evidence, actually linked to a YouTube video which they referred to as “peer reviewed”)
  • One commenter was none other than the titular subject of the post, Rodney Palmer himself.  Here is a screen shot of what he said: Screen shot of the Libel/Slander threat.
  • Knowing full well the story of the libel threat against Simon Singh, I’ve always thought that if ever a threat like that came my way, I’d happily beat it back with the righteous fury and good humour of a person with the facts on their side.  After all, if I’m wrong, you’d be able to prove me wrong, rather than try to shut me up with a threat of a lawsuit.  Indeed, I’ve been through a similar situation once before, so I should be an old hat at this! Let me tell you friends, it’s not that easy.  In fact, it’s awful.  Outside observers could easily identify that Palmer had no case against me, but that was still cold comfort to me.  It is a very stressful situation to find yourself in.
  • The state of libel and slander laws in this country are such that a person can threaten a lawsuit without actually threatening a lawsuit.  There is no need to hire a lawyer to investigate the claims, look into who I am, where I live, where I work, and issue a carefully worded threatening letter demanding compliance.  All a person has to say is some version of  “Libel.  Slander.  Hmmmm….,” and that’s enough to spook a lot of people into backing off. It’s a modern day bogeyman.  They don’t have to prove it.  They don’t have to act on it.  A person or organization just has to say “BOO!” with sufficient seriousness, and unless you’ve got a good deal of editorial and financial support, discussion goes out the window. Libel Chill refers to the ‘chilling effect’ that the possibility of a libel/slander lawsuit has.  If a person is scared they might get sued, then they won’t even comment on a piece at all.  In my case, I had already commented three times on the wifi scaremongering, but this bogus threat against me was surely a major contributing factor to my not commenting again.
  • I ceased to discuss anything in the comment thread of the original article, and even shied away from other comment threads, calling me out.  I learned a great deal about the wifi/EMF issue since I wrote the article, but I did not comment on any of it, because I knew that Palmer and his supporters were watching me like a hawk (sorry to stretch the simile), and would likely try to silence me again.  I couldn’t risk a lawsuit.  Even though I knew there was no case against me, I couldn’t afford a lawyer just to prove that I didn’t do anything illegal.
  • The Libel and Slanders Act of Ontario, 1990 hasn’t really caught up with the internet.  There isn’t a clear precedent that defines a blog post, Twitter feed or Facebook post as falling under the umbrella of “broadcast,” which is what the bill addresses.  If I had written the original article in print, Palmer would have had six weeks to file suit against me.  But the internet is only kind of considered ‘broadcast.’  So it could be just six weeks, but he could also have up to two years to act and get a lawyer after me.  Truth is, there’s not a clear demarcation point for our Canadian legal system.
  • Libel laws in Canada are somewhere in between the Plaintiff-favoured UK system, and the Defendant-favoured US system.  On the one hand, if Palmer chose to incur the expense and time to hire a lawyer and file suit against me, the burden of proof would be on me to prove that I did not act with malice.  Easy peasy.  On the other hand, I would have a strong case that I acted in the best interests of Canadians, which would fall under the recent Supreme Court of Canada decision on protecting what has been termed, “Responsible Communication.”  The Supreme Court of Canada decision does not grant bloggers immunity from libel and slander suits, but it is a healthy dose of welcome freedom to discuss issues of importance to Canadians.
  • Palmer himself did not specify anything against me in his threat.  There was nothing particular that he complained about, he just said a version of “Libel and Slander!” at me.  He may as well have said “Boo!”
  • This is not a DBAD discussion (although I wholeheartedly agree with Phil Plait there). 
  • If you’d like to boil my lessons down to an acronym, I suppose the best one would be DBRBC: Don’t be reckless. Be Careful.
  • I wrote a piece that, although it was not incorrect in any measurable way, was written with fire and brimstone, piss and vinegar.  I stand by my piece, but I caution others to be a little more careful with the language they use.  Not because I think it is any less or more tactically advantageous (because I’m not sure anyone can conclusively demonstrate that being an aggressive jerk is an inherently better or worse communication tool), but because the risks aren’t always worth it.
  • I’m not saying don’t go after a person.  There are egomaniacs out there who deserve to be called out and taken down (verbally, of course).  But be very careful with what you say.
  • ask yourself some questions first: 1) What goal(s) are you trying to accomplish with this piece? Are you trying to convince people that there is a scientific misunderstanding here?  Are you trying to attract the attention of the mainstream media to a particular facet of the issue?  Are you really just pissed off and want to vent a little bit?  Is this article a catharsis, or is it communicative?  Be brutally honest with your intentions, it’s not as easy as you think.  Venting is okay.  So is vicious venting, but be careful what you dress it up as.
  • 2) In order to attain your goals, did you use data, or personalities?  If the former, are you citing the best, most current data you have available to you? Have you made a reasonable effort to check your data against any conflicting data that might be out there? If the latter, are you providing a mountain of evidence, and not just projecting onto personalities?  There is nothing inherently immoral or incorrect with going after the personalities.  But it is a very risky undertaking. You have to be damn sure you know what you’re talking about, and damn ready to defend yourself.  If you’re even a little loose with your claims, you will be called out for it, and a legal threat is very serious and stressful. So if you’re going after a personality, is it worth it?
  • 3) Are you letting the science speak for itself?  Are you editorializing?  Are you pointing out what part of your piece is data and what part is your opinion?
  • 4) If this piece was written in anger, frustration, or otherwise motivated by a powerful emotion, take a day.  Let your anger subside.  It will.  There are many cathartic enterprises out there, and you don’t need to react to the first one that comes your way.  Let someone else read your work before you share it with the internet.  Cooler heads definitely do think more clearly.

Edge: HOW DOES OUR LANGUAGE SHAPE THE WAY WE THINK? By Lera Boroditsky - 0 views

Language Sapir-Whorf Thesis Social Construction

  • Do the languages we speak shape the way we see the world, the way we think, and the way we live our lives? Do people who speak different languages think differently simply because they speak different languages? Does learning new languages change the way you think? Do polyglots think differently when speaking different languages?
  • For a long time, the idea that language might shape thought was considered at best untestable and more often simply wrong. Research in my labs at Stanford University and at MIT has helped reopen this question. We have collected data around the world: from China, Greece, Chile, Indonesia, Russia, and Aboriginal Australia.
  • What we have learned is that people who speak different languages do indeed think differently and that even flukes of grammar can profoundly affect how we see the world.
  • ...15 more annotations...
  • Suppose you want to say, "Bush read Chomsky's latest book." Let's focus on just the verb, "read." To say this sentence in English, we have to mark the verb for tense; in this case, we have to pronounce it like "red" and not like "reed." In Indonesian you need not (in fact, you can't) alter the verb to mark tense. In Russian you would have to alter the verb to indicate tense and gender. So if it was Laura Bush who did the reading, you'd use a different form of the verb than if it was George. In Russian you'd also have to include in the verb information about completion. If George read only part of the book, you'd use a different form of the verb than if he'd diligently plowed through the whole thing. In Turkish you'd have to include in the verb how you acquired this information: if you had witnessed this unlikely event with your own two eyes, you'd use one verb form, but if you had simply read or heard about it, or inferred it from something Bush said, you'd use a different verb form.
  • Clearly, languages require different things of their speakers. Does this mean that the speakers think differently about the world? Do English, Indonesian, Russian, and Turkish speakers end up attending to, partitioning, and remembering their experiences differently just because they speak different languages?
  • For some scholars, the answer to these questions has been an obvious yes. Just look at the way people talk, they might say. Certainly, speakers of different languages must attend to and encode strikingly different aspects of the world just so they can use their language properly. Scholars on the other side of the debate don't find the differences in how people talk convincing. All our linguistic utterances are sparse, encoding only a small part of the information we have available. Just because English speakers don't include the same information in their verbs that Russian and Turkish speakers do doesn't mean that English speakers aren't paying attention to the same things; all it means is that they're not talking about them. It's possible that everyone thinks the same way, notices the same things, but just talks differently.
  • Believers in cross-linguistic differences counter that everyone does not pay attention to the same things: if everyone did, one might think it would be easy to learn to speak other languages. Unfortunately, learning a new language (especially one not closely related to those you know) is never easy; it seems to require paying attention to a new set of distinctions. Whether it's distinguishing modes of being in Spanish, evidentiality in Turkish, or aspect in Russian, learning to speak these languages requires something more than just learning vocabulary: it requires paying attention to the right things in the world so that you have the correct information to include in what you say.
  • Follow me to Pormpuraaw, a small Aboriginal community on the western edge of Cape York, in northern Australia. I came here because of the way the locals, the Kuuk Thaayorre, talk about space. Instead of words like "right," "left," "forward," and "back," which, as commonly used in English, define space relative to an observer, the Kuuk Thaayorre, like many other Aboriginal groups, use cardinal-direction terms — north, south, east, and west — to define space.1 This is done at all scales, which means you have to say things like "There's an ant on your southeast leg" or "Move the cup to the north northwest a little bit." One obvious consequence of speaking such a language is that you have to stay oriented at all times, or else you cannot speak properly. The normal greeting in Kuuk Thaayorre is "Where are you going?" and the answer should be something like " Southsoutheast, in the middle distance." If you don't know which way you're facing, you can't even get past "Hello."
  • The result is a profound difference in navigational ability and spatial knowledge between speakers of languages that rely primarily on absolute reference frames (like Kuuk Thaayorre) and languages that rely on relative reference frames (like English).2 Simply put, speakers of languages like Kuuk Thaayorre are much better than English speakers at staying oriented and keeping track of where they are, even in unfamiliar landscapes or inside unfamiliar buildings. What enables them — in fact, forces them — to do this is their language. Having their attention trained in this way equips them to perform navigational feats once thought beyond human capabilities. Because space is such a fundamental domain of thought, differences in how people think about space don't end there. People rely on their spatial knowledge to build other, more complex, more abstract representations. Representations of such things as time, number, musical pitch, kinship relations, morality, and emotions have been shown to depend on how we think about space. So if the Kuuk Thaayorre think differently about space, do they also think differently about other things, like time? This is what my collaborator Alice Gaby and I came to Pormpuraaw to find out.
  • To test this idea, we gave people sets of pictures that showed some kind of temporal progression (e.g., pictures of a man aging, or a crocodile growing, or a banana being eaten). Their job was to arrange the shuffled photos on the ground to show the correct temporal order. We tested each person in two separate sittings, each time facing in a different cardinal direction. If you ask English speakers to do this, they'll arrange the cards so that time proceeds from left to right. Hebrew speakers will tend to lay out the cards from right to left, showing that writing direction in a language plays a role.3 So what about folks like the Kuuk Thaayorre, who don't use words like "left" and "right"? What will they do? The Kuuk Thaayorre did not arrange the cards more often from left to right than from right to left, nor more toward or away from the body. But their arrangements were not random: there was a pattern, just a different one from that of English speakers. Instead of arranging time from left to right, they arranged it from east to west. That is, when they were seated facing south, the cards went left to right. When they faced north, the cards went from right to left. When they faced east, the cards came toward the body and so on. This was true even though we never told any of our subjects which direction they faced. The Kuuk Thaayorre not only knew that already (usually much better than I did), but they also spontaneously used this spatial orientation to construct their representations of time.
  • I have described how languages shape the way we think about space, time, colors, and objects. Other studies have found effects of language on how people construe events, reason about causality, keep track of number, understand material substance, perceive and experience emotion, reason about other people's minds, choose to take risks, and even in the way they choose professions and spouses.8 Taken together, these results show that linguistic processes are pervasive in most fundamental domains of thought, unconsciously shaping us from the nuts and bolts of cognition and perception to our loftiest abstract notions and major life decisions. Language is central to our experience of being human, and the languages we speak profoundly shape the way we think, the way we see the world, the way we live our lives.
  • The fact that even quirks of grammar, such as grammatical gender, can affect our thinking is profound. Such quirks are pervasive in language; gender, for example, applies to all nouns, which means that it is affecting how people think about anything that can be designated by a noun.
  • How does an artist decide whether death, say, or time should be painted as a man or a woman? It turns out that in 85 percent of such personifications, whether a male or female figure is chosen is predicted by the grammatical gender of the word in the artist's native language. So, for example, German painters are more likely to paint death as a man, whereas Russian painters are more likely to paint death as a woman.
  • Does treating chairs as masculine and beds as feminine in the grammar make Russian speakers think of chairs as being more like men and beds as more like women in some way? It turns out that it does. In one study, we asked German and Spanish speakers to describe objects having opposite gender assignment in those two languages. The descriptions they gave differed in a way predicted by grammatical gender. For example, when asked to describe a "key" — a word that is masculine in German and feminine in Spanish — the German speakers were more likely to use words like "hard," "heavy," "jagged," "metal," "serrated," and "useful," whereas Spanish speakers were more likely to say "golden," "intricate," "little," "lovely," "shiny," and "tiny." To describe a "bridge," which is feminine in German and masculine in Spanish, the German speakers said "beautiful," "elegant," "fragile," "peaceful," "pretty," and "slender," and the Spanish speakers said "big," "dangerous," "long," "strong," "sturdy," and "towering." This was true even though all testing was done in English, a language without grammatical gender. The same pattern of results also emerged in entirely nonlinguistic tasks (e.g., rating similarity between pictures). And we can also show that it is aspects of language per se that shape how people think: teaching English speakers new grammatical gender systems influences mental representations of objects in the same way it does with German and Spanish speakers. Apparently even small flukes of grammar, like the seemingly arbitrary assignment of gender to a noun, can have an effect on people's ideas of concrete objects in the world.
  • Even basic aspects of time perception can be affected by language. For example, English speakers prefer to talk about duration in terms of length (e.g., "That was a short talk," "The meeting didn't take long"), while Spanish and Greek speakers prefer to talk about time in terms of amount, relying more on words like "much" "big", and "little" rather than "short" and "long" Our research into such basic cognitive abilities as estimating duration shows that speakers of different languages differ in ways predicted by the patterns of metaphors in their language. (For example, when asked to estimate duration, English speakers are more likely to be confused by distance information, estimating that a line of greater length remains on the test screen for a longer period of time, whereas Greek speakers are more likely to be confused by amount, estimating that a container that is fuller remains longer on the screen.)
  • An important question at this point is: Are these differences caused by language per se or by some other aspect of culture? Of course, the lives of English, Mandarin, Greek, Spanish, and Kuuk Thaayorre speakers differ in a myriad of ways. How do we know that it is language itself that creates these differences in thought and not some other aspect of their respective cultures? One way to answer this question is to teach people new ways of talking and see if that changes the way they think. In our lab, we've taught English speakers different ways of talking about time. In one such study, English speakers were taught to use size metaphors (as in Greek) to describe duration (e.g., a movie is larger than a sneeze), or vertical metaphors (as in Mandarin) to describe event order. Once the English speakers had learned to talk about time in these new ways, their cognitive performance began to resemble that of Greek or Mandarin speakers. This suggests that patterns in a language can indeed play a causal role in constructing how we think.6 In practical terms, it means that when you're learning a new language, you're not simply learning a new way of talking, you are also inadvertently learning a new way of thinking. Beyond abstract or complex domains of thought like space and time, languages also meddle in basic aspects of visual perception — our ability to distinguish colors, for example. Different languages divide up the color continuum differently: some make many more distinctions between colors than others, and the boundaries often don't line up across languages.
  • To test whether differences in color language lead to differences in color perception, we compared Russian and English speakers' ability to discriminate shades of blue. In Russian there is no single word that covers all the colors that English speakers call "blue." Russian makes an obligatory distinction between light blue (goluboy) and dark blue (siniy). Does this distinction mean that siniy blues look more different from goluboy blues to Russian speakers? Indeed, the data say yes. Russian speakers are quicker to distinguish two shades of blue that are called by the different names in Russian (i.e., one being siniy and the other being goluboy) than if the two fall into the same category. For English speakers, all these shades are still designated by the same word, "blue," and there are no comparable differences in reaction time. Further, the Russian advantage disappears when subjects are asked to perform a verbal interference task (reciting a string of digits) while making color judgments but not when they're asked to perform an equally difficult spatial interference task (keeping a novel visual pattern in memory). The disappearance of the advantage when performing a verbal task shows that language is normally involved in even surprisingly basic perceptual judgments — and that it is language per se that creates this difference in perception between Russian and English speakers.
  • What it means for a language to have grammatical gender is that words belonging to different genders get treated differently grammatically and words belonging to the same grammatical gender get treated the same grammatically. Languages can require speakers to change pronouns, adjective and verb endings, possessives, numerals, and so on, depending on the noun's gender. For example, to say something like "my chair was old" in Russian (moy stul bil' stariy), you'd need to make every word in the sentence agree in gender with "chair" (stul), which is masculine in Russian. So you'd use the masculine form of "my," "was," and "old." These are the same forms you'd use in speaking of a biological male, as in "my grandfather was old." If, instead of speaking of a chair, you were speaking of a bed (krovat'), which is feminine in Russian, or about your grandmother, you would use the feminine form of "my," "was," and "old."

    For a long time, the idea that language might shape thought was considered at best untestable and more often simply wrong. Research in my labs at Stanford University and at MIT has helped reopen this question. We have collected data around the world: from China, Greece, Chile, Indonesia, Russia, and Aboriginal Australia. What we have learned is that people who speak different languages do indeed think differently and that even flukes of grammar can profoundly affect how we see the world. Language is a uniquely human gift, central to our experience of being human. Appreciating its role in constructing our mental lives brings us one step closer to understanding the very nature of humanity.

  • But not all documentaries take such a novel approach. Randy Olson, a marine biologist-turned-filmmaker at the University of Southern California, is a harsh critic of what he sees as a very literal-minded, information-heavy approach within the environmental film genre. Well-intentioned environmental documentary filmmakers are just “making their same, boring, linear, one-dimensional explorations of issues,” said Olson. “The public’s not buying it.”
  • The problem may run deeper than audience tallies — after all, An Inconvenient Truth currently ranks as the sixth-highest grossing documentary in the United States. However, a 2010 study by social psychologist Jessica Nolan found that while the film increased viewers’ concern about global warming, that concern didn’t translate into any substantial action a month later.
  • To move a larger audience to action, Olson advocates a shift from the literal-minded world of documentary into the imaginative world of narrative.
  • ...4 more annotations...
  • One organization using this approach is the Science and Entertainment Exchange, a program of the National Academy of Sciences. The Exchange puts writers, producers, and directors in touch with scientists and engineers who can answer specific questions or just brainstorm ideas. For example, writers for the TV show Fringe changed their original plot point of mind control through hypnosis to magnetic manipulation of brain waves after speaking with a neuroscientist at the Salk Institute for Biological Studies in La Jolla, California.
  • Hollywood, Health and Society (HHS), a program of the Centers for Disease Control and Prevention, takes a similar approach by providing free resources to the entertainment industry. HHS connects writers and producers — from prime time dramas like Law and Order and House to daytime soap operas – with experts who can provide accurate health information for their scripts.
  • HHS Director Sandra Buffington admits that environmental issues, especially climate change, pose particular challenges for communicators because at first glance, they are not as immediately relevant as personal health issues. However, she believes that by focusing on real, human stories — climate refugees displaced by rising water levels, farmers unable to grow food because of drought, children sick because of outbreaks of malaria — the issues of the planet will crystallize into something tangible. All scientists need to do is provide the information, and the professional creative storytellers will do the rest, she says.
  • Olson also takes a cue from television. He points to the rise of reality TV shows as a clear indication of where the general public interest lies. If environmentalists want to capture that interest, Olson thinks they need to start experimenting with these innovative types of unscripted forms. “That’s where the cutting edge exists,” he said.

    For environmentalists trying to use entertainment to shape broad public attitudes and behaviors, nothing could be more important than understanding how to reach these hard-to-get people. Something that will speak to them, something that will change their minds, and most importantly, something that will incite them to action. A documentary might not be that something.

At issue is how far constitutional protections of free speech and expression, as well as due process, can be applied to youngsters.
  • Justice Clarence Thomas also dissented, saying the law's requirement of having parents purchase the games for their underage children was reasonable. "The freedom of speech as originally understood, does not include a right to speak to minors, without going through the minors' parents or guardians," he said.
  • The motion picture industry has its own self-monitoring ratings system, imposed decades ago after complaints that some films were too explicit for the general audience in what was seen and heard. The gaming industry says its ratings system roughly follows the same self-imposed guidelines, and ratings are clearly labeled on the packaging.

  • Efforts in at least eight other states to restrict gaming content have been rejected by various courts.

Nine states also agree, noting California's law has good intentions but would compel law enforcement to become "culture critics" and "distract from the task of policing actual violence."

    The Supreme Court has struck down a California law that would have banned selling "violent" video games to children, a case balancing free speech rights with consumer protection. The 7-2 ruling Monday is a victory for video game makers and sellers, who said the ban -- which had yet to go into effect -- would extend too far. They say the existing nationwide, industry-imposed, voluntary rating system is an adequate screen for parents to judge the appropriateness of computer game content. The state says it has a legal obligation to protect children from graphic interactive images when the industry has failed to do so.

  • Sweeney said she has no idea why Google searches seem to single out black-sounding names. There could be myriad issues at play, some associated with the software, some with the people searching Google. For example, the more often searchers click on a particular ad, the more frequently it is displayed subsequently. “Since we don’t know the reason for it,” she said, “it’s hard to say what you need to do.”
  • But Danny Sullivan, editor of SearchEngineLand.com, an online trade publication that tracks the Internet search and advertising business, said Sweeney’s research has stirred a tempest in a teapot. “It looks like this fairly isolated thing that involves one advertiser.” He also said that the results could be caused by black Google users clicking on those ads as much as white users. “It could be that black people themselves could be causing the stuff that causes the negative copy to be selected more,” said Sullivan. “If most of the searches for black names are done by black people . . . is that racially biased?”
  • On the other hand, Sullivan said Sweeney has uncovered a problem with online searching — the casual display of information that might put someone in a bad light. Rather than focusing on potential instances of racism, he said, search services such as Google might want to put more restrictions on displaying negative information about anyone, black or white.

  • So what exactly are tomorrow’s protectors of biodiversity watching? Everything from the weirdly adorable, like a slow loris being tickled, to the shocking, like an eagle throwing a goat off a cliff, to the oddly fascinating, like a hamster pretending, on cue, to get shot and die, to the graphically sexual — I’ll leave these to you to discover — to the hilarious and disturbing, like one in which the violent sneeze of a baby panda panics its huge mother. If all of this just looks like a lot of time-wasting silliness, ask yourself: Could flash cards more effectively acquaint children with the slow loris? Could there be a more memorable illustration of the “apparent death” response than the performance of this Oscar-worthy hamster? And could anything make you feel more connected with giant pandas, the whole species, than watching one comically startle at the sound of its cub’s crazed sneeze?
  • If the Internet is unavoidable and ubiquitous — and it is — then nature is following right along with it, shining out through screens everywhere. Young people are knowledgeable about organisms in a global way we could never have been as children.

  • A letter Paul wrote to complain about the "The Dead Sea Scrolls" exhibition at the Arts House:To Ms. Amira Osman (Marketing and Communications Manager),cc.Colin Goh, General Manager,Florence Lee, Depury General ManagerDear Ms. Osman,I visited the Dead Sea Scrolls “exhibition” today with my wife. Thinking that it was from a legitimate scholarly institute or (how naïve of me!) the Israel Antiquities Authority, I was looking forward to a day of education and entertainment.Yet when I got it, much of the exhibition (and booklets) merely espouses an evangelical (fundamentalist) view of the Bible – there are booklets on the inerrancy of the Bible, on how archaeology has proven the Bible to be true etc.Apart from these there are many blatant misrepresentations of the state of archaeology and mainstream biblical scholarship:a) There was initial screening upon entry of a 5-10 minute pseudo-documentary on the Dead Sea Scrolls. A presenter (can’t remember the name) was described as a “biblical archaeologist” – a term that no serious archaeologist working in the Levant would apply to him or herself. (Some prefer the term “Syro-Palestinian archaeologist” but almost all reject the term “biblical archaeologist”). See the book by Thomas W. Davis, “Shifting Sands: The Rise and Fall of Biblical Archaeology”, Oxford, New York 2004. Davis is an actual archaeologist working in the field and the book tells why the term “Biblical archaeologist” is not considered a legitimate term by serious archaeologist.b) In the same presentation, the presenter made the erroneous statement that the entire old testament was translated into Greek in the third century BCE. This is a mistake – only the Pentateuch (the first five books of the Old Testament) was translated during that time. Note that this ‘error’ is not inadvertent but is a familiar claim by evangelical apologists who try to argue for an early date of all the books of the Old testament - if all the books have been translated by the third century BCE obviously these books must all have been written before then! This flies against modern scholarship which show that some books in the Old Testament such as the Book of Daniel was written only in the second century BCE]The actual state of scholarship on the Septuagint [The Greek translation of the Bible] is accurately given in the book by Ernst Würthwein, “The Text of the Old Testament” – Eerdmans 1988 pp.52-54c) Perhaps the most blatant error was one which claimed that the “Magdalene fragments” – which contains the 26th chapter of the Gospel of Matthew is dated to 50 AD!!! Scholars are unanimous in dating these fragments to 200 AD. The only ‘scholar’ cited that dated these fragments to 50 AD was the German papyrologist Carsten Thiede – a well know fundamentalist. This is what Burton Mack (a critical – legitimate – NT scholar) has to say about Thiede’s eccentric dating “From a critical scholar's point of view, Thiede's proposal is an example of just how desperate the Christian imagination can become in the quest to argue for the literal facticity of the Christian gospels” [Mack, Burton L., “Who Wrote the New Testament?:The Making of the Christian Myth” HarperCollins, San Francisco 1995] Yet the dating of 50 AD is presented as though it is a scholarly consensus position!In fact the last point was so blatant that I confronted the exhibitors. (Tak Boleh Tahan!!) One American exhibitor told me that “Yes, it could have been worded differently, but then we would have to change the whole display” (!!). When I told him that this was not a typo but a blatant attempt to deceive, he mentioned that Theide’s views are supported by “The Dallas Theological Seminary” – another well know evangelical institute!I have no issue with the religious strengthening their faith by having their own internal exhibitions on historical artifacts etc. But when it is presented to the public as a scholarly exhibition – this is quite close to being dishonest.I felt cheated of the $36 dollars I paid for the tickets and of the hour that I spent there before realizing what type of exhibition it was.I am disappointed with The Art House for show casing this without warning potential visitors of its clear religious bias.Yours sincerely,Paul TobinTo their credit, the Arts House speedily replied.

Spivak for example, argued for the deconstruction by means of questioning the privilege of identity so that someone is believed to have the truth.

  • It’s too soon to say that Twitter and Facebook destroy the mental foundations of morality, but not too soon to ask what they’re doing.
  • In the paper, published Monday in the Proceedings of the National Academy of Sciences, 13 people were shown documentary-style multimedia narratives designed to arouse empathy. Researchers recorded their brain activity and found that empathy is as deeply rooted in the human psyche as fear and anger.
  • They also noticed that empathic brain systems took an average of six to eight seconds to start up. The researchers didn’t connect this to media consumption habits, but the study’s press release fueled speculation that the Facebook generation could turn into sociopaths.
  • ...6 more annotations...
  • Entitled "Can Twitter Make You Amoral? Rapid-fire Media May Confuse Your Moral Compass," it claimed that the research "raises questions about the emotional cost —particularly for the developing brain — of heavy reliance on a rapid stream of news snippets obtained through television, online feeds or social networks such as Twitter."
  • Compared to in-depth news coverage, first-person Tweets of on-the-ground events, such as the 2008 Mumbai bombings, is generally unmoving. But in those situations, Twitter’s primary use is in gathering useful, immediate facts, not storytelling.
  • Most people who read a handful of words about a friend’s heartache, or see a link to a tragic story, would likely follow it up. But following links to a video news story makes the possibility of a short-circuited neurobiology of compassion becomes more real. Research suggests that people are far more empathic when stories are told in a linear way, without quick shot-to-shot edits. In a 1996 Empirical Studies of the Arts paper, researchers showed three versions of an ostensibly tear-jerking story to 120 test subjects. "Subjects had significantly more favorable impressions of the victimized female protagonist than of her male opponent only when the story structure was linear," they concluded.
  • A review of tabloid news formats in the Journal of Broadcasting & Electronic Media found that jarring, rapid-fire visual storytelling produced a physiological arousal led to better recall of what was seen, but only if the original subject matter was dull. If it was already arousing, tabloid storytelling appeared to produce a cognitive overload that actually prevented stories from sinking in.
  • "Quick cuts will draw and retain a viewer’s focus even if the content is uninteresting," said freelance video producer Jill Bauerle. "MTV-like jump cuts, which have become the standard for many editors, serve as a sort of eye candy to keep eyeballs peeled to screen."
  • f compassion can only be activated by sustained attention, which is prevented by fast-cut editing, then the ability to be genuinely moved by another’s story could atrophy. It might even fail to properly develop in children, whose brains are being formed in ways that will last a lifetime. More research is clearly needed, including a replication of the original empathy findings, but the hypothesis is plausible.

  • Plucking out of line most of the vaguely Middle Eastern-looking men at the airport for heightened screening is no more effective at catching terrorists than randomly sampling everyone. It may even be less effective. Press stumbled across this counterintuitive concept — sometimes the best way to find something is not to weight it by probability — in the unrelated context of computational biology. The parallels to airport security struck him when a friend mentioned he was constantly being pulled out of line at the airport.
  • Racial profiling, in other words, doesn’t work because it devotes heightened resources to innocent people — and then devotes those resources to them repeatedly even after they’ve been cleared as innocent the first time. The actual terrorists, meanwhile, may sneak through while Transportation Security Administration agents are focusing their limited attention on the wrong passengers.
  • Press tested the theory in a series of probability equations (the ambitious can check his math here and here).
  • ...3 more annotations...
  • Sampling based on profiling is mathematically no more effective than uniform random sampling. The optimal equation, rather, turns out to be something called “square-root sampling,” a compromise between the other two methods.
  • “Crudely,” Press writes of his findings in the journal Significance, if certain people are “nine times as likely to be the terrorist, we pull out only three times as many of them for special checks. Surprisingly, and bizarrely, this turns out to be the most efficient way of catching the terrorist.”
  • Square-root sampling, though, still represents a kind of profiling, and, Press adds, not one that could be realistically implemented at airports today. Square-root sampling only works if the profile probabilities are accurate in the first place — if we are able to say with mathematical certainty that some types of people are “nine times as likely to be the terrorist” compared to others. TSA agents in a crowded holiday terminal making snap judgments about facial hair would be far from this standard. “The nice thing about uniform sampling is there’s nothing to be inaccurate about, you don’t need any data, it never can be worse than you expect,” Press said. “As soon as you use profile probabilities, if the profile probabilities are just wrong, then the strong profiling just does worse than the random sampling.”
