  • When chicks were exposed to puffs of air, they showed signs of distress that were mirrored by their mothers. The hens' heart rate increased, their eye temperature lowered - a recognised stress sign - and they became increasingly alert. Levels of preening were reduced, and the hens made more clucking noises directed at their chicks.
  • Researcher Jo Edgar, from the School of Veterinary Sciences at the University of Bristol, said: ''The extent to which animals are affected by the distress of others is of high relevance to the welfare of farm and laboratory animals. ''Our research has addressed the fundamental question of whether birds have the capacity to show empathic responses.

    "Moral certainty is always a sign of cultural inferiority. The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant, in this field as in all others. His culture is based on "I am not too sure.""

Likert Scale Statistics Level of Measurement Pandora's Box Latour

shared by Weiye Loh on 16 Feb 11 - Cached
  • Whether individual Likert items can be considered as interval-level data, or whether they should be considered merely ordered-categorical data is the subject of disagreement. Many regard such items only as ordinal data, because, especially when using only five levels, one cannot assume that respondents perceive all pairs of adjacent levels as equidistant. On the other hand, often (as in the example above) the wording of response levels clearly implies a symmetry of response levels about a middle category; at the very least, such an item would fall between ordinal- and interval-level measurement; to treat it as merely ordinal would lose information. Further, if the item is accompanied by a visual analog scale, where equal spacing of response levels is clearly indicated, the argument for treating it as interval-level data is even stronger.
  • When treated as ordinal data, Likert responses can be collated into bar charts, central tendency summarised by the median or the mode (but some would say not the mean), dispersion summarised by the range across quartiles (but some would say not the standard deviation), or analyzed using non-parametric tests, e.g. chi-square test, Mann–Whitney test, Wilcoxon signed-rank test, or Kruskal–Wallis test.[4] Parametric analysis of ordinary averages of Likert scale data is also justifiable by the Central Limit Theorem, although some would disagree that ordinary averages should be used for Likert scale data.

  • Governments often fall down on all three: they have a particular ideology and so push a single-minded policy; they bet big; and they don’t bother to evaluate the results too carefully, perhaps through overconfidence. But markets can fail badly too, and for much the same reason. Just think about the subprime crisis. It failed the same three tests. First, many big banks and insurance companies were taking similar bets at similar times, so that when subprime loans started to go bad, much of Wall Street started struggling simultaneously. Second, the bets were gigantic. Fancy derivatives such as credit default swaps and complex mortgage-backed securities were new, rapidly growing, and largely untested. And third, many investment bankers were being paid large bonuses on the assumption that their performance could be measured properly – and it couldn’t, because profitable-seeming bets concealed large risks.
  • a study by Kathy Fogel, Randall Morck, and Bernard Yeung, found statistical evidence that economies with more churn in the corporate sector also had faster economic growth. The relationship even seems causal: churn today is correlated with fast economic growth tomorrow. The real benefit of this creative destruction, say Fogel and her colleagues, is not the appearance of “rising stars” but the disappearance of old, inefficient companies. Failure is not only common and unpredictable, it’s healthy.

Meet Science: What is "peer review"? - Boing Boing - 0 views

Fraud Academic Research Peer Review Academic Journal

shared by Weiye Loh on 22 Apr 11 - No Cached
  • Scientists do complain about peer review. But let me set one thing straight: The biggest complaints scientists have about peer review are not that it stifles unpopular ideas. You've heard this truthy factoid from countless climate-change deniers, and purveyors of quack medicine. And peer review is a convenient scapegoat for their conspiracy theories. There's just enough truth to make the claims sound plausible.
  • Peer review is flawed. Peer review can be biased. In fact, really new, unpopular ideas might well have a hard time getting published in the biggest journals right at first. You saw an example of that in my interview with sociologist Harry Collins. But those sort of findings will often published by smaller, more obscure journals. And, if a scientist keeps finding more evidence to support her claims, and keeps submitting her work to peer review, more often than not she's going to eventually convince people that she's right. Plenty of scientists, including Harry Collins, have seen their once-shunned ideas published widely.
  • So what do scientists complain about? This shouldn't be too much of a surprise. It's the lack of training, the lack of feedback, the time constraints, and the fact that, the more specific your research gets, the fewer people there are with the expertise to accurately and thoroughly review your work.
  • ...5 more annotations...
  • Scientists are frustrated that most journals don't like to publish research that is solid, but not ground-breaking. They're frustrated that most journals don't like to publish studies where the scientist's hypothesis turned out to be wrong.
  • Some scientists would prefer that peer review not be anonymous—though plenty of others like that feature. Journals like the British Medical Journal have started requiring reviewers to sign their comments, and have produced evidence that this practice doesn't diminish the quality of the reviews.
  • There are also scientists who want to see more crowd-sourced, post-publication review of research papers. Because peer review is flawed, they say, it would be helpful to have centralized places where scientists can go to find critiques of papers, written by scientists other than the official peer-reviewers. Maybe the crowd can catch things the reviewers miss. We certainly saw that happen earlier this year, when microbiologist Rosie Redfield took a high-profile peer-reviewed paper about arsenic-based life to task on her blog. The website Faculty of 1000 is attempting to do something like this. You can go to that site, look up a previously published peer-reviewed paper, and see what other scientists are saying about it. And the Astrophysics Archive has been doing this same basic thing for years.
  • you shouldn't canonize everything a peer-reviewed journal article says just because it is a peer-reviewed journal article.
  • at the same time, being peer reviewed is a sign that the paper's author has done some level of due diligence in their work. Peer review is flawed, but it has value. There are improvements that could be made. But, like the old joke about democracy, peer review is the worst possible system except for every other system we've ever come up with.
  • Weiye Loh on 22 Apr 11
     
    Being peer reviewed doesn't mean your results are accurate. Not being peer reviewed doesn't mean you're a crank. But the fact that peer review exists does weed out a lot of cranks, simply by saying, "There is a standard." Journals that don't have peer review do tend to be ones with an obvious agenda. White papers, which are not peer reviewed, do tend to contain more bias and self-promotion than peer-reviewed journal articles.

  • One thing is for sure–traditional publishing isn’t getting anymore lucrative. That means under the current system, if you’re not selling a sure thing, publishers probably aren’t going to buy it. Hopefully crowdfunding sites like Unbound can change all of that–it sure beats waiting for a wealthy benefactor, anyway.

Creativity Education

shared by Weiye Loh on 11 Jul 10 - Cached
  • The accepted definition of creativity is production of something original and useful, and that’s what’s reflected in the tests. There is never one right answer. To be creative requires divergent thinking (generating many unique ideas) and then convergent thinking (combining those ideas into the best result).
  • Torrance’s tasks, which have become the gold standard in creativity assessment, measure creativity perfectly. What’s shocking is how incredibly well Torrance’s creativity index predicted those kids’ creative accomplishments as adults.
  • The correlation to lifetime creative accomplishment was more than three times stronger for childhood creativity than childhood IQ.
  • ...20 more annotations...
  • there is one crucial difference between IQ and CQ scores. With intelligence, there is a phenomenon called the Flynn effect—each generation, scores go up about 10 points. Enriched environments are making kids smarter. With creativity, a reverse trend has just been identified and is being reported for the first time here: American creativity scores are falling.
  • creativity scores had been steadily rising, just like IQ scores, until 1990. Since then, creativity scores have consistently inched downward.
  • It is the scores of younger children in America—from kindergarten through sixth grade—for whom the decline is “most serious.”
  • It’s too early to determine conclusively why U.S. creativity scores are declining. One likely culprit is the number of hours kids now spend in front of the TV and playing videogames rather than engaging in creative activities. Another is the lack of creativity development in our schools. In effect, it’s left to the luck of the draw who becomes creative: there’s no concerted effort to nurture the creativity of all children.
  • Around the world, though, other countries are making creativity development a national priority.
  • In China there has been widespread education reform to extinguish the drill-and-kill teaching style. Instead, Chinese schools are also adopting a problem-based learning approach.
  • When faculty of a major Chinese university asked Plucker to identify trends in American education, he described our focus on standardized curriculum, rote memorization, and nationalized testing.
  • Overwhelmed by curriculum standards, American teachers warn there’s no room in the day for a creativity class.
  • The age-old belief that the arts have a special claim to creativity is unfounded. When scholars gave creativity tasks to both engineering majors and music majors, their scores laid down on an identical spectrum, with the same high averages and standard deviations.
  • The argument that we can’t teach creativity because kids already have too much to learn is a false trade-off. Creativity isn’t about freedom from concrete facts. Rather, fact-finding and deep research are vital stages in the creative process.
  • The lore of pop psychology is that creativity occurs on the right side of the brain. But we now know that if you tried to be creative using only the right side of your brain, it’d be like living with ideas perpetually at the tip of your tongue, just beyond reach.
  • Creativity requires constant shifting, blender pulses of both divergent thinking and convergent thinking, to combine new information with old and forgotten ideas. Highly creative people are very good at marshaling their brains into bilateral mode, and the more creative they are, the more they dual-activate.
  • “Creativity can be taught,” says James C. Kaufman, professor at California State University, San Bernardino. What’s common about successful programs is they alternate maximum divergent thinking with bouts of intense convergent thinking, through several stages. Real improvement doesn’t happen in a weekend workshop. But when applied to the everyday process of work or school, brain function improves.
  • highly creative adults tended to grow up in families embodying opposites. Parents encouraged uniqueness, yet provided stability. They were highly responsive to kids’ needs, yet challenged kids to develop skills. This resulted in a sort of adaptability: in times of anxiousness, clear rules could reduce chaos—yet when kids were bored, they could seek change, too. In the space between anxiety and boredom was where creativity flourished.
  • highly creative adults frequently grew up with hardship. Hardship by itself doesn’t lead to creativity, but it does force kids to become more flexible—and flexibility helps with creativity.
  • In early childhood, distinct types of free play are associated with high creativity. Preschoolers who spend more time in role-play (acting out characters) have higher measures of creativity: voicing someone else’s point of view helps develop their ability to analyze situations from different perspectives. When playing alone, highly creative first graders may act out strong negative emotions: they’ll be angry, hostile, anguished.
  • In middle childhood, kids sometimes create paracosms—fantasies of entire alternative worlds. Kids revisit their paracosms repeatedly, sometimes for months, and even create languages spoken there. This type of play peaks at age 9 or 10, and it’s a very strong sign of future creativity.
  • From fourth grade on, creativity no longer occurs in a vacuum; researching and studying become an integral part of coming up with useful solutions. But this transition isn’t easy. As school stuffs more complex information into their heads, kids get overloaded, and creativity suffers. When creative children have a supportive teacher—someone tolerant of unconventional answers, occasional disruptions, or detours of curiosity—they tend to excel. When they don’t, they tend to underperform and drop out of high school or don’t finish college at high rates.
  • They’re quitting because they’re discouraged and bored, not because they’re dark, depressed, anxious, or neurotic. It’s a myth that creative people have these traits. (Those traits actually shut down creativity; they make people less open to experience and less interested in novelty.) Rather, creative people, for the most part, exhibit active moods and positive affect. They’re not particularly happy—contentment is a kind of complacency creative people rarely have. But they’re engaged, motivated, and open to the world.
  • A similar study of 1,500 middle schoolers found that those high in creative self-efficacy had more confidence about their future and ability to succeed. They were sure that their ability to come up with alternatives would aid them, no matter what problems would arise.

Identity sexuality fluidity

shared by Weiye Loh on 07 Oct 09 - Cached
  • All of this fluidity, confusion and experimentation can be understandably disorienting for parents and educators. Is an eighth grader who says he’s gay just experimenting? Could he change his mind in a week, as 13-year-olds routinely do with other identities — skater, prep, goth, jock — they try on for a while and then shed for another? And if sexuality is so fluid, should he really box himself in with a gay identity? Many parents told me they especially struggled with that last question.
    • Weiye Loh

      Could this fluidity be a methodology for survival? A play of signs and seduction? In what way could it be informed by the new media? I am reminded of Peter Steiner's dog-on-internet comic.
  • A year earlier they asked Austin if he was gay after they discovered his call to a gay chat line. He promised them that he was straight, and he promised himself that he would cover his tracks better. It’s not uncommon for gay youth to have their same-sex attraction discovered thanks to a rogue number on a phone bill or, more often these days, a poorly concealed Internet search history. “We see a lot of kids get outed by porn on the computer,” Tim Gillean told me in Tulsa. “I knew one kid who told his mom: ‘I don’t know how that got there. Maybe it was dad!’ ”

Rationally Speaking: Should non-experts shut up? The skeptic's catch-22 - 0 views

Science Communication skepticism

shared by Weiye Loh on 17 Jul 10 - Cached
  • You can read the talk here, but in a nutshell, Massimo was admonishing skeptics who reject the scientific consensus in fields in which they have no technical expertise - the most notable recent example of this being anthropogenic climate change, about which venerable skeptics like James Randi and Michael Shermer have publicly expressed doubts (though Shermer has since changed his mind).
  • I'm totally with Massimo that it seems quite likely that anthropogenic climate change is really happening. But I'm not sure I can get behind Massimo's broader argument that non-experts should defer to the expert consensus in a field.
  • First of all, while there are strong incentives for a researcher to find errors in other work in the field, there are strong disincentives for her to challenge the field's foundational assumptions. It will be extremely difficult for her to get other people to agree with her if she tries, and if she succeeds, she'll still be taking herself down along with the rest of the field.
  • ...7 more annotations...
  • Second of all, fields naturally select for people who accept their foundational assumptions. People who don't accept those assumptions are likely not to have gone into that field in the first place, or to have left it already.
  • Sometimes those foundational assumptions are simple enough that an outsider can evaluate them - for instance, I may not be an expert in astrology or theology, but I can understand their starting premises (stars affect human fates; we should accept the Bible as the truth) well enough to confidently dismiss them, and the fields that rest on them. But when the foundational assumptions get more complex - like the assumption that we can reliably model future temperatures - it becomes much harder for an outsider to judge their soundness.
  • we almost seem to be stuck in a Catch-22: The only people who are qualified to evaluate the validity of a complex field are the ones who have studied that field in depth - in other words, experts. Yet the experts are also the people who have the strongest incentives not to reject the foundational assumptions of the field, and the ones who have self-selected for believing those assumptions. So the closer you are to a field, the more biased you are, which makes you a poor judge of it; the farther away you are, the less relevant knowledge you have, which makes you a poor judge of it. What to do?
  • luckily, the Catch-22 isn't quite as stark as I made it sound. For example, you can often find people who are experts in the particular methodology used by a field without actually being a member of the field, so they can be much more unbiased judges of whether that field is applying the methodology soundly. So for example, a foundational principle underlying a lot of empirical social science research is that linear regression is a valid tool for modeling most phenomena. I strongly recommend asking a statistics professor about that. 
  • there are some general criteria that outsiders can use to evaluate the validity of a technical field, even without “technical scientific expertise” in that field. For example, can the field make testable predictions, and does it have a good track record of predicting things correctly? This seems like a good criterion by which an outsider can judge the field of climate modeling (and "predictions" here includes using your model to predict past data accurately). I don't need to know how the insanely-complicated models work to know that successful prediction is a good sign.
  • And there are other more field-specific criteria outsiders can often use. For example, I've barely studied postmodernism at all, but I don't have to know much about the field to recognize that the fact that they borrow concepts from complex disciplines which they themselves haven't studied is a red flag.
  • the issue with AGW is less the science and all about the political solutions. Most every solution we hear in the public conversation requires some level of sacrifice and uncertainty in the future.Politicians, neither experts in climatology nor economics, craft legislation to solve the problem through the lens of their own political ideology. At TAM8, this was pretty apparent. My honest opinion is that people who are AGW skeptics are mainly skeptics of the political solutions. If AGW was said to increase the GDP of the country by two to three times, I'm guessing you'd see a lot less climate change skeptics.

  • The notion that one can do anything is clearly liberating. But life without constraints has also proved a recipe for endless searching, endless questioning of aspirations. It has made this generation obsessed with self-development and determined, for as long as possible, to minimise personal commitments in order to maximise the options open to them. One might see this as a sign of extended adolescence. Eventually, they will be forced to realise that living is as much about closing possibilities as it is about creating them.

Cryonics Evidence

shared by Weiye Loh on 22 Sep 10 - Cached
  • cryonics offers almost eternal life. To its critics, cryonics is pseudoscience; the idea that we could freeze someone today in such a way that future technology might be able to re-animate them is nothing more than wishful thinking on the desire to avoid death. Many who battle nonsense dressed as science have spoken out against it: see for example Nano Nonsense and Cryonics, a 2001 article by celebrated skeptic Michael Shermer; or check the Skeptic’s Dictionary or Quackwatch entries on the subject, or for more detail read the essay Cryonics–A futile desire for everlasting life by “Invisible Flan”.
  • And of course the pro-cryonics people have written reams and reams of material such as Ben Best’s Scientific Justification of Cryonics Practice on why they think this is exactly as plausible as I might think, and going into tremendous technical detail setting out arguments for its plausibility and addressing particular difficulties. It’s almost enough to make you want to sign up on the spot. Except, of course, that plenty of totally unscientific ideas are backed by reams of scientific-sounding documents good enough to fool non-experts like me. Backed by the deep pockets of the oil industry, global warming denialism has produced thousands of convincing-sounding arguments against the scientific consensus on CO2 and AGW. T
  • Nano Nonsense and Cryonics goes for the nitty-gritty right away in the opening paragraph:To see the flaw in this system, thaw out a can of frozen strawberries. During freezing, the water within each cell expands, crystallizes, and ruptures the cell membranes. When defrosted, all the intracellular goo oozes out, turning your strawberries into runny mush. This is your brain on cryonics.This sounds convincing, but doesn’t address what cryonicists actually claim. Ben Best, President and CEO of the Cryonics Institute, replies in the comments:Strawberries (and mammalian tissues) are not turned to mush by freezing because water expands and crystallizes inside the cells. Water crystallizes in the extracellular space because more nucleators are found extracellularly. As water crystallizes in the extracellular space, the extracellular salt concentration increases causing cells to lose water osmotically and shrink. Ultimately the cell membranes are broken by crushing from extracellular ice and/or high extracellular salt concentration. […] Cryonics organizations use vitrification perfusion before cooling to cryogenic temperatures. With good brain perfusion, vitrification can reduce ice formation to negligible amounts.
  • ...6 more annotations...
  • The Skeptic’s Dictionary entry is no advance. Again, it refers erroneously to a “mushy brain”. It points out that the technology to reanimate those in storage does not already exist, but provides no help for us non-experts in assessing whether it is a plausible future technology, like super-fast computers or fusion power, or whether it is as crazy as the sand-powered tank; it simply asserts baldly and to me counterintuitively that it is the latter. Again, perhaps cryonic reanimation is a sand-powered tank, but I can explain to you why a sand-powered tank is implausible if you don’t already know, and if cryonics is in the same league I’d appreciate hearing the explanation.
  • Another part of the article points out the well-known difficulties with whole-body freezing — because the focus is on achieving the best possible preservation of the brain, other parts suffer more. But the reason why the brain is the focus is that you can afford to be a lot bolder in repairing other parts of the body — unlike the brain, if my liver doesn’t survive the freezing, it can be replaced altogether.
  • Further, the article ignores one of the most promising possibilities for reanimation, that of scanning and whole-brain emulation, a route that requires some big advances in computer and scanning technology as well as our understanding of the lowest levels of the brain’s function, but which completely sidesteps any problems with repairing either damage from the freezing process or whatever it was that led to legal death.
  • Sixteen years later, it seems that hasn’t changed; in fact, as far as the issue of technical feasability goes it is starting to look as if on all the Earth, or at least all the Internet, there is not one person who has ever taken the time to read and understand cryonics claims in any detail, still considers it pseudoscience, and has written a paper, article or even a blog post to rebut anything that cryonics advocates actually say. In fact, the best of the comments on my first blog post on the subject are already a higher standard than anything my searches have turned up.
  • I don’t have anything useful to add, I just wanted to say that I feel exactly as you do about cryonics and living forever. And I thought that this statement: I know that I don’t know enough to judge. shows extreme wisdom. If only people wishing to comment on global warming would apply the same test.
  • WRT global warming, the mistake people make is trying to go direct to the first-order evidence, which is much too complicated and too easy to misrepresent to hope to directly interpret unless you make it your life’s work, and even then only in a particular area. The correct thing to do is to collect second-order evidence, such as that every major scientific academy has backed the IPCC.

  • What is important in Zuckerberg’s story is not that he’s a boy genius. He plainly is, but many are. It’s not that he’s a socially clumsy (relative to the Harvard elite) boy genius. Every one of them is. And it’s not that he invented an amazing product through hard work and insight that millions love. The history of American entrepreneurism is just that history, told with different technologies at different times and places.
  • what’s important here is that Zuckerberg’s genius could be embraced by half-a-billion people within six years of its first being launched, without (and here is the critical bit) asking permission of anyone. The real story is not the invention. It is the platform that makes the invention sing. Zuckerberg didn’t invent that platform. He was a hacker (a term of praise) who built for it. And as much as Zuckerberg deserves endless respect from every decent soul for his success, the real hero in this story doesn’t even get a credit. It’s something Sorkin doesn’t even notice.
  • Zuckerberg faced no such barrier. For less than $1,000, he could get his idea onto the Internet. He needed no permission from the network provider. He needed no clearance from Harvard to offer it to Harvard students. Neither with Yale, or Princeton, or Stanford. Nor with every other community he invited in. Because the platform of the Internet is open and free, or in the language of the day, because it is a “neutral network,” a billion Mark Zuckerbergs have the opportunity to invent for the platform. And though there are crucial partners who are essential to bring the product to market, the cost of proving viability on this platform has dropped dramatically. You don’t even have to possess Zuckerberg’s technical genius to develop your own idea for the Internet today.

      What a shallow techno-utopianist view...

  • that is tragedy because just at the moment when we celebrate the product of these two wonders—Zuckerberg and the Internet—working together, policymakers are conspiring ferociously with old world powers to remove the conditions for this success. As “network neutrality” gets bargained away—to add insult to injury, by an administration that was elected with the promise to defend it—the opportunities for the Zuckerbergs of tomorrow will shrink. And as they do, we will return more to the world where success depends upon permission. And privilege. And insiders. And where fewer turn their souls to inventing the next great idea.
  • Zuckerberg is a rightful hero of our time. I want my kids to admire him. To his credit, Sorkin gives him the only lines of true insight in the film: In response to the twins’ lawsuit, he asks, does “a guy who makes a really good chair owe money to anyone who ever made a chair?” And to his partner who signed away his ownership in Facebook: “You’re gonna blame me because you were the business head of the company and you made a bad business deal with your own company?” Friends who know Zuckerberg say such insight is common. No doubt his handlers are panicked that the film will tarnish the brand. He should listen less to these handlers. As I looked around at the packed theater of teens and twenty-somethings, there was no doubt who was in the right, however geeky and clumsy and sad. That generation will judge this new world. If, that is, we allow that new world to continue to flourish.

Wikileaks Pentagon Papers

  • Ex-Intelligence Officers, Others See Plusses in WikiLeaks Disclosures
  • The following statement was released today, signed by Daniel Ellsberg, Frank Grevil, Katharine Gun, David MacMichael, Ray McGovern, Craig Murray, Coleen Rowley and Larry Wilkerson; all are associated with Sam Adams Associates for Integrity in Intelligence.
  • How far down the U.S. has slid can be seen, ironically enough, in a recent commentary in Pravda (that’s right, Russia’s Pravda): “What WikiLeaks has done is make people understand why so many Americans are politically apathetic … After all, the evils committed by those in power can be suffocating, and the sense of powerlessness that erupts can be paralyzing, especially when … government evildoers almost always get away with their crimes. …”
  • ...6 more annotations...
  • shame on Barack Obama, Eric Holder, and all those who spew platitudes about integrity, justice and accountability while allowing war criminals and torturers to walk freely upon the earth. … the American people should be outraged that their government has transformed a nation with a reputation for freedom, justice, tolerance and respect for human rights into a backwater that revels in its criminality, cover-ups, injustices and hypocrisies.
  • As part of their attempt to blacken WikiLeaks and Assange, pundit commentary over the weekend has tried to portray Assange’s exposure of classified materials as very different from — and far less laudable than — what Daniel Ellsberg did in releasing the Pentagon Papers in 1971. Ellsberg strongly rejects the mantra “Pentagon Papers good; WikiLeaks material bad.” He continues: “That’s just a cover for people who don’t want to admit that they oppose any and all exposure of even the most misguided, secretive foreign policy. The truth is that EVERY attack now made on WikiLeaks and Julian Assange was made against me and the release of the Pentagon Papers at the time.”
  • WikiLeaks’ reported source, Army Pvt. Bradley Manning, having watched Iraqi police abuses, and having read of similar and worse incidents in official messages, reportedly concluded, “I was actively involved in something that I was completely against.” Rather than simply go with the flow, Manning wrote: “I want people to see the truth … because without information you cannot make informed decisions as a public,” adding that he hoped to provoke worldwide discussion, debates, and reform.
  • The media: again, the media is key. No one has said it better than Monseñor Romero of El Salvador, who just before he was assassinated 25 years ago warned, “The corruption of the press is part of our sad reality, and it reveals the complicity of the oligarchy.” Sadly, that is also true of the media situation in America today.
  • The big question is not whether Americans can “handle the truth.” We believe they can. The challenge is to make the truth available to them in a straightforward way so they can draw their own conclusions — an uphill battle given the dominance of the mainstream media, most of which have mounted a hateful campaign to discredit Assange and WikiLeaks.
  • So far, the question of whether Americans can “handle the truth” has been an academic rather than an experience-based one, because Americans have had very little access to the truth. Now, however, with the WikiLeaks disclosures, they do. Indeed, the classified messages from the Army and the State Department released by WikiLeaks are, quite literally, “ground truth.”

  • t was the big news that wasn’t. Hyperbolic claims about the possible discovery of alien life, or a second branch of life on Earth, turned out to be nothing more than bacteria that can thrive on arsenic, using it in place of phosphorus in their DNA and other molecules. But after the initial layers of hype were peeled away, even this extraordinar
  • This is a chronological roundup of the criticism against the science in the paper itself, ending with some personal reflections on my own handling of the story (skip to Friday, December 10th for that bit).
  • Thursday, December 2nd: Felisa Wolfe-Simon published a paper in Science, claiming to have found bacteria in California’s Mono Lake that can grow using arsenic instead of phosphorus. Given that phosphorus is meant to be one of six irreplaceable elements, this would have been a big deal, not least because the bacteria apparently used arsenic to build the backbones of their DNA molecules.
  • ...14 more annotations...
  • In my post, I mentioned some caveats. Wolfe-Simon isolated the arsenic-loving strain, known as GFAJ-1, by growing Mono Lake bacteria in ever-increasing concentrations of arsenic while diluting out the phosphorus. It is possible that the bacteria’s arsenic molecules were an adaptation to the harsh environments within the experiment, rather than Mono Lake itself. More importantly, there were still detectable levels of phosphorus left in the cells at the end of the experiment, although Wolfe-Simon claimed that the bacteria shouldn’t have been able to grow on such small amounts.
  • signs emerged that NASA weren’t going to engage with the criticisms. Dwayne Brown, their senior public affairs officer, highlighted the fact that the paper was published in one of the “most prestigious scientific journals” and deemed it inappropriate to debate the science using the same media and bloggers who they relied on for press coverage of the science. Wolfe-Simon herself tweeted that “discussion about scientific details MUST be within a scientific venue so that we can come back to the public with a unified understanding.”
  • Jonathan Eisen says that “they carried out science by press release and press conference” and “are now hypocritical if they say that the only response should be in the scientific literature.” David Dobbs calls the attitude “a return to pre-Enlightenment thinking”, and rightly noted that “Rosie Redfield is a peer, and her blog is peer review”.
  • Chris Rowan agreed, saying that what happens after publication is what he considers to be “real peer review”. Rowan said, “The pre-publication stuff is just a quality filter, a check that the paper is not obviously wrong – and an imperfect filter at that. The real test is what happens in the months and years after publication.”Grant Jacobs and others post similar thoughts, while Nature and the Columbia Journalism Review both cover the fracas.
  • Jack Gilbert at the University of Chicago said that impatient though he is, peer-reviewed journals are the proper forum for criticism. Others were not so kind. At the Guardian, Martin Robbins says that “at almost every stage of this story the actors involved were collapsing under the weight of their own slavish obedience to a fundamentally broken… well… ’system’” And Ivan Oransky noted that NASA failed to follow its own code of conduct when announcing the study.
  • Dr Isis said, “If question remains about the voracity of these authors findings, then the only thing that is going to answer that doubt is data.  Data cannot be generated by blog discussion… Talking about digging a ditch never got it dug.”
  • it is astonishing how quickly these events unfolded and the sheer number of bloggers and media outlets that became involved in the criticism. This is indeed a brave new world, and one in which we are all the infamous Third Reviewer.
  • I tried to quell the hype around the study as best I could. I had the paper and I think that what I wrote was a fair representation of it. But, of course, that’s not necessarily enough. I’ve argued before that journalists should not be merely messengers – we should make the best possible efforts to cut through what’s being said in an attempt to uncover what’s actually true. Arguably, that didn’t happen although to clarify, I am not saying that the paper is rubbish or untrue. Despite the criticisms, I want to see the authors respond in a thorough way or to see another lab attempt replicate the experiments before jumping to conclusions.
  • the sheer amount of negative comment indicates that I could have been more critical of the paper in my piece. Others have been supportive in suggesting that this was more egg on the face of the peer reviewers and indeed, several practicing scientists took the findings on face value, speculating about everything from the implications for chemotherapy to whether the bacteria have special viruses. The counter-argument, which I have no good retort to, is that peer review is no guarantee of quality, and that writers should be able to see through the fog of whatever topic they write about.
  • my response was that we should expect people to make reasonable efforts to uncover truth and be skeptical, while appreciating that people can and will make mistakes.
  • it comes down to this: did I do enough? I was certainly cautious. I said that “there is room for doubt” and I brought up the fact that the arsenic-loving bacteria still contain measurable levels of phosphorus. But I didn’t run the paper past other sources for comment, which I typically do it for stories that contain extraordinary claims. There was certainly plenty of time to do so here and while there were various reasons that I didn’t, the bottom line is that I could have done more. That doesn’t always help, of course, but it was an important missed step. A lesson for next time.
  • I do believe that it you’re going to try to hold your profession to a higher standard, you have to be honest and open when you’ve made mistakes yourself. I also think that if you cover a story that turns out to be a bit dodgy, you have a certain responsibility in covering the follow-up
  • A basic problem with is the embargo. Specifically that journalists get early access, while peers – other specialists in the field – do not. It means that the journalist, like yourself, can rely only on the original authors, with no way of getting other views on the findings. And it means that peers can’t write about the paper when the journalists (who, inevitably, do a positive-only coverage due to the lack of other viewpoints) do, but will be able to voice only after they’ve been able to digest the paper and formulate a response.
  • No, that’s not true. The embargo doens’t preclude journalists from sending papers out to other authors for review and comment. I do this a lot and I have been critical about new papers as a result, but that’s the step that I missed for this story.

American Airlines worker fired for replying to web user complaint - Telegraph - 0 views

  • American Airlines has been caught in a row over customer engagement after it fired a contract worker for responding to a complaint about their website.
  • Mr Curtis, an American web designer, was unimpressed by his experience using the the AA.com website, and made that clear in a lengthy open letter to the company on his blog, complete with a suggested redesign of the homepage (see the gallery above), saying he would be “ashamed” of the site. He also suggested that they fire their design team.
  • Mr X, a web designer, responded to the letter, saying in a long email that Mr Curtis was "so very right" about the problems of the website, but that it was less to do with staff incompetence and more to do with the internal culture of the airline. Mr X also told Mr Curtis that they were improving the website, but that it was a slow process. By speaking to Mr Curtis, however, Mr X was in breach of a non-disclosure agreement (NDA) he had signed with AA, barring him from revealing sensitive information.

  • after bosses at American Airlines became aware of Mr X's response, they searched through their email database, found his identity and fired him for a breach of the NDA. Mr Curtis says he is "horrified" at Mr X's treatment. He said on his blog: "AA fired Mr X because he cared. They fired him because he cared enough to reach out to a dissatisfied customer and help clear the company's name in the best way he could."
