On the Media: Survey shows that not all polls are equal - latimes.com - 0 views

  • Internet surveys sometimes acknowledge how unscientific (read: meaningless) they really are. They surely must be a pale imitation of the rigorous, carefully sampled, thoroughly transparent polls favored by political savants and mainstream news organizations
  • The line between junk and credible polling remains. But it became a little blurrier — creating concern among professional survey organizations and reason for greater skepticism by all of us — because of charges this week that one widely cited pollster may have fabricated data or manipulated it so seriously as to render it meaningless.

  • The firm's protestations that it did nothing wrong have been loud and repeated. Evidence against the company is somewhat arcane. Suffice it to say that independent statisticians have found a bewildering lack of statistical "noise" in the company's data. Where random variation would be expected, results are too consistent.
  • Most reputable pollsters agree on one thing — polling organizations should publicly disclose as much of their methodology as possible. Just for starters, they should reveal how many people were interviewed, how they were selected, how many rejected the survey, how "likely voters" and other sub-groups were defined and how the raw data was weighted to reflect the population, or subgroups.
  • Michael Cornfield, a George Washington University political scientist and polling expert, recommends that concerned citizens ignore the lone, sometimes sensational, poll result. "Trend data are superior to a single point in time," Cornfield said via e-mail, "and consensus results from multiple firms are superior to those conducted by a single outfit."
  • The rest of us should look at none of the polls. Or look at all of them. And look out for the operators not willing to tell us how they're doing business.

  • These play to a primitive impulse to respond to immediate opportunities and threats. The stimulation provokes excitement — a dopamine squirt — that researchers say can be addictive.
  • While many people say multitasking makes them more productive, research shows otherwise. Heavy multitaskers actually have more trouble focusing and shutting out irrelevant information, scientists say, and they experience more stress.

Liberal Democrat conference | Libel laws silence scientists | Richard Dawkins | Comment... - 0 views

  • Scientists often disagree with one another, sometimes passionately. But they don't go to court to sort out their differences, they go into the lab, repeat the experiments, carefully examine the controls and the statistical analysis. We care about whether something is true, supported by the evidence. We are not interested in whether somebody sincerely believes he is right.

      Exactly the reason why appeals to faith cannot work in secularism!!! Unfortunately, people who are unable to prove their point usually resort to underhand straw-in-nose methods; throw enough shit and hopefully some will stay.

BBC NEWS | Science & Environment | Honesty test 'should be reviewed' - 0 views

  • The study found that 88.5% women believed buying a dress for a special occasion and then returning it to the store and getting a refund was dishonest. Broccoli stalks But just 46.7% took the same view of a care home nurse persuading an elderly patient to change a will in her favour. A large majority of men had a similar attitude, with 82.6% thinking it was morally wrong to "borrow" the dress but only 37.6% disapproving of taking advantage of someone who was elderly and infirm. The findings suggested that if a jury of 12 men and women was asked to pass a verdict on the care home nurse, only four would want to convict. HAVE YOUR SAY There is a wide variation in what people feel is acceptable Peter Symonds Send us your comments A higher proportion of women, 82.2%, thought it was dishonest to lie about age on an internet dating site than believed it was wrong to benefit from the will alteration. In a league table of dishonest acts, conning the elderly care home patient came 13th out of 16 - just one place above snapping off broccoli stalks in a supermarket and weighing the heads.

  • Forget about trying to catch doping. It’s a game the “good guys” can never win. Stop testing at all, and declare open season. Treat doping as just something else that the sportsmen can do to improve their performance, much the same as spending money on a good bike isn’t considered cheating.

Balderdash: Anthony Grayling on Atheism - 0 views

  • we're all familiar with Popper's dictum that if a theory, a claim explains everything, if everything is consistent with the truth of the claim, then it's empty. It doesn't explain anything at all. [On the claim that Science purports to explain everything, or that it claims that it will be able to eventually] I don't think Science does claim that at all, in fact. Science at its normal best: it is a public, a testable, a challengeable project. Always having to maintain its own respectability by saying what would count as counter-evidence against it. And when people put forward views in Science, they publish them so that other people can test them, review them, try to replicate results, and I think that is absolutely the model of how an epistemology should proceed. Out there in the open and inviting the very toughest kind of response from other people...

The nature of the good life, which make no appeal whatever to any divine command.

Paul Crowley's Blog - A survey of anti-cryonics writing - 0 views

  • 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.

  • 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.

I am Singaporean VI - The Melting Pot « Die neue Welle - 0 views

  • On paper, Singaporean education is great. Our universities are in the Top 200 in the Times Higher Education list. We win Olympiads all the time. When it comes to knowing a basic inventory of facts, Singaporean education is just about the best you can get. And that is a fact.
  • So what’s missing?
  • Singapore is a true melting pot. In the past, as is today, and as will be tomorrow, many cultures came together into one. It has been lauded as one of Singapore’s big selling points – an eclectic fusion of Orient and Occident, a quaint East-meets-West mixture which happens to work. But have we taken this metaphor and looked at it from another perspective? Many cultures came together under the band of meritocracy – may the best rule, and may they rule with wisdom. And since they are the best, they are paid the best money one can get too. This is the fire which managed to melt, or should i say meld East and West into a functioning whole. And since we are such fans of meritocracy, society has been geared in that direction too. This melting pot which is Singapore has had certain repercussions, which the post I have linked to above shows. It seems that in developing the concept of meritocracy, what “The Best” is was artificially defined. And in artificially defining something, you create an artificial standard to compare everything against. In doing so, everything else becomes irrelevant. It creates a strong tendency towards conformity, which is the negative result of the melting pot. The individual loses his/her uniqueness and becomes part of this stew of uniformity. In school, you are told to study hard, you are told what you have to study, without any care as to what you actually think.
  • ...6 more annotations...
  • Individuality is not really encouraged, because there is a tried-and-tested formula for becoming good. Why would any sane person abandon that?
  • And, by the by, an artificial standard of what is Good is also very easy to objectify. Just look at the obsession with grades, and the thought that cramming is the panacea for all your examination woes.
  • in the midst of all that, something has gone missing. I think learning what it is to be a person has gone missing in Singaporean education. People assume that a sense of identity is a coming-of-age thing, that it will come with the times. And for the most part, that really is true. But this article is a case in point. I think that the melting pot has left little room for the individual to develop, since all differences have been swept away, and everyone is chasing after this artificial Good.
  • That having an individual opinion is sometimes seen as trouble-making is a symptom of this problem. That people know a lot, but don’t have a view on them is also a symptom of this problem. It’s all about working hard in Singapore. But after that, what’s left? Yet, working hard and sticking to that same old success formula is so ingrained into our society that it is hard to see how concrete change can come about.
  • We should be asking questions if “The Good” we are striving to be was misconstrued. We should be asking “What is Good for Me? What Should I Be?” And these are questions which should be asked, not only during the formative years of adolesence, but also constantly throughout one’s adult life. And these are questions which don’t have a textbook answer. And the asking of such questions should be cultivated in our youth, when they are ready for it.
  • We shouldn’t be doing what we are doing now – filling their lives with so much work, so much obsession with chasing after this artificial good that they don’t have time to stop and reflect. Nor will forcing them to reflect help – because then, it will be more work, and what’s worse, their reflections may be graded. The melting pot comes into play again. As educators, one should ask if we want to produce smart people or if we want  to produce wise people.

Management of gays revisited, part 1 « Yawning Bread on Wordpress - 0 views

  • Michael Hor noted that despite the vocal attempts to demonise gay people and paint homosexual orientation as injurious (including by some members of the ruling party) the government did not subscribe to such reasoning. Yet the government chose to keep the law.
  • The “key speech arguing for the retention of 377A” that Hor refers to was that made by Thio. Hor then goes on to discover that the government’s decision was bi-layered. The surface justification, going by the prime minister’s words, was that it would be symbolic — a “signpost of heterosexual orthodoxy”. Hor next asks what the motivation might be for wanting such a symbol. He examines the possibility that it could be to steer people towards heterosexual orientation, yet the government itself, from its own words, does not believe so.
  • As was well-known, the anti-gay movement was religiously inspired. The government however was neither dictated nor swayed by them, Hor said. In fact, the government “roundly rejected” the movement’s essential beliefs. Still, it appears that the government did not want to annoy them any further by leaving them empty-handed. That motivation alone made the government decide to retain 377A.
  • ...6 more annotations...
  • But, Hor points out, Page 340: to give legislative effect to a norm which stems almost exclusively from Christian or Muslim beliefs does appear to be a curiously misguided decision. Take the example of the prohibition against eating pork — certainly a tenet of Islam and Judaism. No one would even suggest that we enact a law banning the consumption of pork in Singapore, even for Muslims, no matter how strongly these two religious communities feel about it.
  • With reference to the constitutional guarantee of equality before the law, Hor explains that this provision requires that, Page 340: law must not be “arbitrary”; there must be a “rational nexus” or “reasonable classification” between what the law targets and the purpose for which it is laid down.
  • Laws must be tested for “fit” and “weight”, he said. With respect to the former, the question is whether the classification of the target persons affected by the law fits the intended purpose of the law. As for “weight”, the question is whether whatever the problem the law purports to deal with is real and serious enough to justify the intervention of criminal sanction. Or is it mostly capricious?
    • Weiye Loh
       
      The weight of the law has to do with the probability that Foucault mentioned. 
  • decision to retain 377A is gravely problematic on both fronts. It does not fit very well at all. . . . If, as we have seen, the legislature was acting in some manner on the antipathy of certain segments of society towards homosexual activity, then the non-inclusion of women in 377A is a very huge omission indeed — more than half our population and presumably half of all homosexual activity.  It would be akin to subjecting half all our cars to a certain speed limit rule based on the colour of the car.
  • The element of “weight” is no less shaky. Can the sole purpose of accommodation of sectarian sensibilities ever be weighty enough to justify the criminalization of private sexual conduct between consenting adults? If the answer is “yes”, then it is hard to imagine for what earthly purpose the equal protection clause was written into the Constitution for. It is not the case that the Legislature has made a judgment that 377A activity is sufficiently harmful to society to attract criminal sanctions. . . the speech of PM Lee shows a clear belief that it is not so harmful — but 377A was to remain for, apparently, the sole purpose of appeasing those who disapprove.
  • It is not difficult to see that if the desire to accommodate a disapproving segment of society is reason enough, that would result in the evisceration of equal protection. . . Equal protection is about protection against prejudice, and if the government does not buy into the substantive arguments (of those who disapprove) for criminalization, then those putative reasons become, as far as the government is concerned, prejudice.
  •  
    In Chapter 19 of a new book Management of Success, Singapore revisited, National University of Singapore law professor Michael Hor makes a strong argument that Section 377A of the Penal Code is unconstitutional. This is the law that makes it an offence for men to have sexual relations with each other, effectively criminalising male homosexuality.

Research integrity: Sabotage! : Nature News - 0 views

  • University of Michigan in Ann Arbor
  • Vipul Bhrigu, a former postdoc at the university's Comprehensive Cancer Center, wears a dark-blue three-buttoned suit and a pinched expression as he cups his pregnant wife's hand in both of his. When Pollard Hines calls Bhrigu's case to order, she has stern words for him: "I was inclined to send you to jail when I came out here this morning."
  • Bhrigu, over the course of several months at Michigan, had meticulously and systematically sabotaged the work of Heather Ames, a graduate student in his lab, by tampering with her experiments and poisoning her cell-culture media. Captured on hidden camera, Bhrigu confessed to university police in April and pleaded guilty to malicious destruction of personal property, a misdemeanour that apparently usually involves cars: in the spaces for make and model on the police report, the arresting officer wrote "lab research" and "cells". Bhrigu has said on multiple occasions that he was compelled by "internal pressure" and had hoped to slow down Ames's work. Speaking earlier this month, he was contrite. "It was a complete lack of moral judgement on my part," he said.
  • ...16 more annotations...
  • Bhrigu's actions are surprising, but probably not unique. There are few firm numbers showing the prevalence of research sabotage, but conversations with graduate students, postdocs and research-misconduct experts suggest that such misdeeds occur elsewhere, and that most go unreported or unpoliced. In this case, the episode set back research, wasted potentially tens of thousands of dollars and terrorized a young student. More broadly, acts such as Bhrigu's — along with more subtle actions to hold back or derail colleagues' work — have a toxic effect on science and scientists. They are an affront to the implicit trust between scientists that is necessary for research endeavours to exist and thrive.
  • Despite all this, there is little to prevent perpetrators re-entering science.
  • federal bodies that provide research funding have limited ability and inclination to take action in sabotage cases because they aren't interpreted as fitting the federal definition of research misconduct, which is limited to plagiarism, fabrication and falsification of research data.
  • In Bhrigu's case, administrators at the University of Michigan worked with police to investigate, thanks in part to the persistence of Ames and her supervisor, Theo Ross. "The question is, how many universities have such procedures in place that scientists can go and get that kind of support?" says Christine Boesz, former inspector-general for the US National Science Foundation in Arlington, Virginia, and now a consultant on scientific accountability. "Most universities I was familiar with would not necessarily be so responsive."
  • Some labs are known to be hyper-competitive, with principal investigators pitting postdocs against each other. But Ross's lab is a small, collegial place. At the time that Ames was noticing problems, it housed just one other graduate student, a few undergraduates doing projects, and the lab manager, Katherine Oravecz-Wilson, a nine-year veteran of the lab whom Ross calls her "eyes and ears". And then there was Bhrigu, an amiable postdoc who had joined the lab in April 2009.
  • Some people whom Ross consulted with tried to convince her that Ames was hitting a rough patch in her work and looking for someone else to blame. But Ames was persistent, so Ross took the matter to the university's office of regulatory affairs, which advises on a wide variety of rules and regulations pertaining to research and clinical care. Ray Hutchinson, associate dean of the office, and Patricia Ward, its director, had never dealt with anything like it before. After several meetings and two more instances of alcohol in the media, Ward contacted the department of public safety — the university's police force — on 9 March. They immediately launched an investigation — into Ames herself. She endured two interrogations and a lie-detector test before investigators decided to look elsewhere.
  • At 4:00 a.m. on Sunday 18 April, officers installed two cameras in the lab: one in the cold room where Ames's blots had been contaminated, and one above the refrigerator where she stored her media. Ames came in that day and worked until 5:00 p.m. On Monday morning at around 10:15, she found that her medium had been spiked again. When Ross reviewed the tapes of the intervening hours with Richard Zavala, the officer assigned to the case, she says that her heart sank. Bhrigu entered the lab at 9:00 a.m. on Monday and pulled out the culture media that he would use for the day. He then returned to the fridge with a spray bottle of ethanol, usually used to sterilize lab benches. With his back to the camera, he rummaged through the fridge for 46 seconds. Ross couldn't be sure what he was doing, but it didn't look good. Zavala escorted Bhrigu to the campus police department for questioning. When he told Bhrigu about the cameras in the lab, the postdoc asked for a drink of water and then confessed. He said that he had been sabotaging Ames's work since February. (He denies involvement in the December and January incidents.)
  • Misbehaviour in science is nothing new — but its frequency is difficult to measure. Daniele Fanelli at the University of Edinburgh, UK, who studies research misconduct, says that overtly malicious offences such as Bhrigu's are probably infrequent, but other forms of indecency and sabotage are likely to be more common. "A lot more would be the kind of thing you couldn't capture on camera," he says. Vindictive peer review, dishonest reference letters and withholding key aspects of protocols from colleagues or competitors can do just as much to derail a career or a research project as vandalizing experiments. These are just a few of the questionable practices that seem quite widespread in science, but are not technically considered misconduct. In a meta-analysis of misconduct surveys, published last year (D. Fanelli PLoS ONE 4, e5738; 2009), Fanelli found that up to one-third of scientists admit to offences that fall into this grey area, and up to 70% say that they have observed them.
  • Some say that the structure of the scientific enterprise is to blame. The big rewards — tenured positions, grants, papers in stellar journals — are won through competition. To get ahead, researchers need only be better than those they are competing with. That ethos, says Brian Martinson, a sociologist at HealthPartners Research Foundation in Minneapolis, Minnesota, can lead to sabotage. He and others have suggested that universities and funders need to acknowledge the pressures in the research system and try to ease them by means of education and rehabilitation, rather than simply punishing perpetrators after the fact.
  • Bhrigu says that he felt pressure in moving from the small college at Toledo to the much bigger one in Michigan. He says that some criticisms he received from Ross about his incomplete training and his work habits frustrated him, but he doesn't blame his actions on that. "In any kind of workplace there is bound to be some pressure," he says. "I just got jealous of others moving ahead and I wanted to slow them down."
  • At Washtenaw County Courthouse in July, having reviewed the case files, Pollard Hines delivered Bhrigu's sentence. She ordered him to pay around US$8,800 for reagents and experimental materials, plus $600 in court fees and fines — and to serve six months' probation, perform 40 hours of community service and undergo a psychiatric evaluation.
  • But the threat of a worse sentence hung over Bhrigu's head. At the request of the prosecutor, Ross had prepared a more detailed list of damages, including Bhrigu's entire salary, half of Ames's, six months' salary for a technician to help Ames get back up to speed, and a quarter of the lab's reagents. The court arrived at a possible figure of $72,000, with the final amount to be decided upon at a restitution hearing in September.
  • Ross, though, is happy that the ordeal is largely over. For the month-and-a-half of the investigation, she became reluctant to take on new students or to hire personnel. She says she considered packing up her research programme. She even questioned her own sanity, worrying that she was the one sabotaging Ames's work via "an alternate personality". Ross now wonders if she was too trusting, and urges other lab heads to "realize that the whole spectrum of humanity is in your lab. So, when someone complains to you, take it seriously."
  • She also urges others to speak up when wrongdoing is discovered. After Bhrigu pleaded guilty in June, Ross called Trempe at the University of Toledo. He was shocked, of course, and for more than one reason. His department at Toledo had actually re-hired Bhrigu. Bhrigu says that he lied about the reason he left Michigan, blaming it on disagreements with Ross. Toledo let Bhrigu go in July, not long after Ross's call.
  • Now that Bhrigu is in India, there is little to prevent him from getting back into science. And even if he were in the United States, there wouldn't be much to stop him. The National Institutes of Health in Bethesda, Maryland, through its Office of Research Integrity, will sometimes bar an individual from receiving federal research funds for a time if they are found guilty of misconduct. But Bhigru probably won't face that prospect because his actions don't fit the federal definition of misconduct, a situation Ross finds strange. "All scientists will tell you that it's scientific misconduct because it's tampering with data," she says.
  • Ames says that the experience shook her trust in her chosen profession. "I did have doubts about continuing with science. It hurt my idea of science as a community that works together, builds upon each other's work and collaborates."

Twitter, Facebook Won't Make You Immoral - But TV News Might | Wired Science | Wired.com - 1 views

  • 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.

nanopolitan: "Lies, Damned Lies, and Medical Science" - 0 views

  • That's the title of The Atlantic profile of Dr. John Ioannidis who "has spent his career challenging his peers by exposing their bad science." His 2005 paper in PLoS Medicine was on why most published research findings are false.
  • Ioannidis anticipated that the community might shrug off his findings: sure, a lot of dubious research makes it into journals, but we researchers and physicians know to ignore it and focus on the good stuff, so what’s the big deal? The other paper headed off that claim.
  • He zoomed in on 49 of the most highly regarded research findings in medicine over the previous 13 years, as judged by the science community’s two standard measures: the papers had appeared in the journals most widely cited in research articles, and the 49 articles themselves were the most widely cited articles in these journals.
  • ...7 more annotations...
  • Of the 49 articles, 45 claimed to have uncovered effective interventions. Thirty-four of these claims had been retested, and 14 of these, or 41 percent, had been convincingly shown to be wrong or significantly exaggerated. If between a third and a half of the most acclaimed research in medicine was proving untrustworthy, the scope and impact of the problem were undeniable. That article was published in the Journal of the American Medical Association. [here's the link.]
  • David Freedman -- has quite a bit on the sociology of research in medical science. Here are a few quotes:
  • Even when the evidence shows that a particular research idea is wrong, if you have thousands of scientists who have invested their careers in it, they’ll continue to publish papers on it,” he says. “It’s like an epidemic, in the sense that they’re infected with these wrong ideas, and they’re spreading it to other researchers through journals.”
  • the peer-review process often pressures researchers to shy away from striking out in genuinely new directions, and instead to build on the findings of their colleagues (that is, their potential reviewers) in ways that only seem like breakthroughs—as with the exciting-sounding gene linkages (autism genes identified!) and nutritional findings (olive oil lowers blood pressure!) that are really just dubious and conflicting variations on a theme.
  • The ultimate protection against research error and bias is supposed to come from the way scientists constantly retest each other’s results—except they don’t. Only the most prominent findings are likely to be put to the test, because there’s likely to be publication payoff in firming up the proof, or contradicting it.
  • Doctors may notice that their patients don’t seem to fare as well with certain treatments as the literature would lead them to expect, but the field is appropriately conditioned to subjugate such anecdotal evidence to study findings.
  • [B]eing wrong in science is fine, and even necessary—as long as scientists recognize that they blew it, report their mistake openly instead of disguising it as a success, and then move on to the next thing, until they come up with the very occasional genuine breakthrough. But as long as careers remain contingent on producing a stream of research that’s dressed up to seem more right than it is, scientists will keep delivering exactly that.

Is Pure Altruism Possible? - NYTimes.com - 0 views

  • It’s undeniable that people sometimes act in a way that benefits others, but it may seem that they always get something in return — at the very least, the satisfaction of having their desire to help fulfilled.
  • Contemporary discussions of altruism quickly turn to evolutionary explanations. Reciprocal altruism and kin selection are the two main theories. According to reciprocal altruism, evolution favors organisms that sacrifice their good for others in order to gain a favor in return. Kin selection — the famous “selfish gene” theory popularized by Richard Dawkins — says that an individual who behaves altruistically towards others who share its genes will tend to reproduce those genes. Organisms may be altruistic; genes are selfish. The feeling that loving your children more than yourself is hard-wired lends plausibility to the theory of kin selection.
  • The defect of reciprocal altruism is clear. If a person acts to benefit another in the expectation that the favor will be returned, the natural response is: “That’s not altruism!”  Pure altruism, we think, requires a person to sacrifice for another without consideration of personal gain. Doing good for another person because something’s in it for the do-er is the very opposite of what we have in mind. Kin selection does better by allowing that organisms may genuinely sacrifice their interests for another, but it fails to explain why they sometimes do so for those with whom they share no genes
  • ...12 more annotations...
  • When we ask whether human beings are altruistic, we want to know about their motives or intentions. Biological altruism explains how unselfish behavior might have evolved but, as Frans de Waal suggested in his column in The Stone on Sunday, it implies nothing about the motives or intentions of the agent: after all, birds and bats and bees can act altruistically. This fact helps to explain why, despite these evolutionary theories, the view that people never intentionally act to benefit others except to obtain some good for themselves still possesses a powerful lure over our thinking.
  • The lure of this view — egoism — has two sources, one psychological, the other logical. Consider first the psychological. One reason people deny that altruism exists is that, looking inward, they doubt the purity of their own motives. We know that even when we appear to act unselfishly, other reasons for our behavior often rear their heads: the prospect of a future favor, the boost to reputation, or simply the good feeling that comes from appearing to act unselfishly. As Kant and Freud observed, people’s true motives may be hidden, even (or perhaps especially) from themselves. Even if we think we’re acting solely to further another person’s good, that might not be the real reason. (There might be no single “real reason” — actions can have multiple motives.)
  • So the psychological lure of egoism as a theory of human action is partly explained by a certain humility or skepticism people have about their own or others’ motives
  • There’s also a less flattering reason: denying the possibility of pure altruism provides a convenient excuse for selfish behavior.
  • The logical lure of egoism is different: the view seems impossible to disprove. No matter how altruistic a person appears to be, it’s possible to conceive of her motive in egoistic terms.
  • The impossibility of disproving egoism may sound like a virtue of the theory, but, as philosophers of science know, it’s really a fatal drawback. A theory that purports to tell us something about the world, as egoism does, should be falsifiable. Not false, of course, but capable of being tested and thus proved false. If every state of affairs is compatible with egoism, then egoism doesn’t tell us anything distinctive about how things are.
  • s ambiguity in the concepts of desire and the satisfaction of desire. If people possess altruistic motives, then they sometimes act to benefit others without the prospect of gain to themselves. In other words, they desire the good of others for its own sake, not simply as a means to their own satisfaction.
  • Still, when our desires are satisfied we normally experience satisfaction; we feel good when we do good. But that doesn’t mean we do good only in order to get that “warm glow” — that our true incentives are self-interested (as economists tend to claim). Indeed, as de Waal argues, if we didn’t desire the good of others for its own sake, then attaining it wouldn’t produce the warm glow.
  • Common sense tells us that some people are more altruistic than others. Egoism’s claim that these differences are illusory — that deep down, everybody acts only to further their own interests — contradicts our observations and deep-seated human practices of moral evaluation.
  • At the same time, we may notice that generous people don’t necessarily suffer more or flourish less than those who are more self-interested.
  • The point is rather that the kind of altruism we ought to encourage, and probably the only kind with staying power, is satisfying to those who practice it. Studies of rescuers show that they don’t believe their behavior is extraordinary; they feel they must do what they do, because it’s just part of who they are. The same holds for more common, less newsworthy acts — working in soup kitchens, taking pets to people in nursing homes, helping strangers find their way, being neighborly. People who act in these ways believe that they ought to help others, but they also want to help, because doing so affirms who they are and want to be and the kind of world they want to exist. As Prof. Neera Badhwar has argued, their identity is tied up with their values, thus tying self-interest and altruism together. The correlation between doing good and feeling good is not inevitable— inevitability lands us again with that empty, unfalsifiable egoism — but it is more than incidental.
  • Altruists should not be confused with people who automatically sacrifice their own interests for others.

Study: Airport Security Should Stop Racial Profiling | Smart Journalism. Real Solutions... - 0 views

  • 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.”

Rationally Speaking: The sorry state of higher education - 0 views

  • two disconcerting articles crossed my computer screen, both highlighting the increasingly sorry state of higher education, though from very different perspectives. The first is “Ed Dante’s” (actually a pseudonym) piece in the Chronicle of Higher Education, entitled The Shadow Scholar. The second is Gregory Petsko’s A Faustian Bargain, published of all places in Genome Biology.
  • There is much to be learned by educators in the Shadow Scholar piece, except the moral that “Dante” would like us to take from it. The anonymous author writes:“Pointing the finger at me is too easy. Why does my business thrive? Why do so many students prefer to cheat rather than do their own work? Say what you want about me, but I am not the reason your students cheat.
  • The point is that plagiarism and cheating happen for a variety of reasons, one of which is the existence of people like Mr. Dante and his company, who set up a business that is clearly unethical and should be illegal. So, pointing fingers at him and his ilk is perfectly reasonable. Yes, there obviously is a “market” for cheating in higher education, and there are complex reasons for it, but he is in a position similar to that of the drug dealer who insists that he is simply providing the commodity to satisfy society’s demand. Much too easy of a way out, and one that doesn’t fly in the case of drug dealers, and shouldn’t fly in the case of ghost cheaters.
  • ...16 more annotations...
  • As a teacher at the City University of New York, I am constantly aware of the possibility that my students might cheat on their tests. I do take some elementary precautionary steps
  • Still, my job is not that of the policeman. My students are adults who theoretically are there to learn. If they don’t value that learning and prefer to pay someone else to fake it, so be it, ultimately it is they who lose in the most fundamental sense of the term. Just like drug addicts, to return to my earlier metaphor. And just as in that other case, it is enablers like Mr. Dante who simply can’t duck the moral blame.
  • n open letter to the president of SUNY-Albany, penned by molecular biologist Gregory Petsko. The SUNY-Albany president has recently announced the closing — for budgetary reasons — of the departments of French, Italian, Classics, Russian and Theater Arts at his university.
  • Petsko begins by taking on one of the alleged reasons why SUNY-Albany is slashing the humanities: low enrollment. He correctly points out that the problem can be solved overnight at the stroke of a pen: stop abdicating your responsibilities as educators and actually put constraints on what your students have to take in order to graduate. Make courses in English literature, foreign languages, philosophy and critical thinking, the arts and so on, mandatory or one of a small number of options that the students must consider in order to graduate.
  • But, you might say, that’s cheating the market! Students clearly don’t want to take those courses, and a business should cater to its customers. That type of reasoning is among the most pernicious and idiotic I’ve ever heard. Students are not clients (if anything, their parents, who usually pay the tuition, are), they are not shopping for a new bag or pair of shoes. They do not know what is best for them educationally, that’s why they go to college to begin with. If you are not convinced about how absurd the students-as-clients argument is, consider an analogy: does anyone with functioning brain cells argue that since patients in a hospital pay a bill, they should be dictating how the brain surgeon operates? I didn’t think so.
  • Petsko then tackles the second lame excuse given by the president of SUNY-Albany (and common among the upper administration of plenty of public universities): I can’t do otherwise because of the legislature’s draconian cuts. Except that university budgets are simply too complicated for there not to be any other option. I know this first hand, I’m on a special committee at my own college looking at how to creatively deal with budget cuts handed down to us from the very same (admittedly small minded and dysfunctional) New York state legislature that has prompted SUNY-Albany’s action. As Petsko points out, the president there didn’t even think of involving the faculty and staff in a broad discussion of how to deal with the crisis, he simply announced the cuts on a Friday afternoon and then ran for cover. An example of very poor leadership to say the least, and downright hypocrisy considering all the talk that the same administrator has been dishing out about the university “community.”
  • Finally, there is the argument that the humanities don’t pay for their own way, unlike (some of) the sciences (some of the time). That is indubitably true, but irrelevant. Universities are not businesses, they are places of higher learning. Yes, of course they need to deal with budgets, fund raising and all the rest. But the financial and administrative side has one goal and one goal only: to provide the best education to the students who attend that university.
  • That education simply must include the sciences, philosophy, literature, and the arts, as well as more technical or pragmatic offerings such as medicine, business and law. Why? Because that’s the kind of liberal education that makes for an informed and intelligent citizenry, without which our democracy is but empty talk, and our lives nothing but slavery to the marketplace.
  • Maybe this is not how education works in the US. I thought that general (or compulsory) education (ie. up to high school) is designed to make sure that citizens in a democratic country can perform their civil duties. A balanced and well-rounded education, which includes a healthy mixture of science and humanities, is indeed very important for this purpose. However, college-level education is for personal growth and therefore the person must have a large say about what kind of classes he or she chooses to take. I am disturbed by Massimo's hospital analogy. Students are not ill. They don't go to college to be cured, or to be good citizens. They go to college to learn things that *they* want to learn. Patients are passive. Students are not.I agree that students typically do not know what kind of education is good for them. But who does?
  • students do have a saying in their education. They pick their major, and there are electives. But I object to the idea that they can customize their major any way they want. That assumes they know what the best education for them is, they don't. That's the point of education.
  • The students are in your class to get a good grade, any learning that takes place is purely incidental. Those good grades will look good on their transcript and might convince a future employer that they are smart and thus are worth paying more.
  • I don't know what the dollar to GPA exchange rate is these days, but I don't doubt that there is one.
  • Just how many of your students do you think will remember the extensive complex jargon of philosophy more than a couple of months after they leave your classroom?
  • and our lives nothing but slavery to the marketplace.We are there. Welcome. Where have you been all this time? In a capitalistic/plutocratic society money is power (and free speech too according to the supreme court). Money means a larger/better house/car/clothing/vacation than your neighbor and consequently better mating opportunities. You can mostly blame the women for that one I think just like the peacock's tail.
  • If a student of surgery fails to learn they might maim, kill or cripple someone. If an engineer of airplanes fails to learn they might design a faulty aircraft that fails and kills people. If a student of chemistry fails to learn they might design a faulty drug with unintended and unfortunate side effects, but what exactly would be the harm if a student of philosophy fails to learn Aristotle had to say about elements or Plato had to say about perfect forms? These things are so divorced from people's everyday activities as to be rendered all but meaningless.
  • human knowledge grows by leaps and bounds every day, but human brain capacity does not, so the portion of human knowledge you can personally hold gets smaller by the minute. Learn (and remember) as much as you can as fast as you can and you will still lose ground. You certainly have your work cut out for you emphasizing the importance of Thales in the Age of Twitter and whatever follows it next year.

Arsenic bacteria - a post-mortem, a review, and some navel-gazing | Not Exactly Rocket ... - 0 views

  • 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.

RealClimate: Feedback on Cloud Feedback - 0 views

  • I have a paper in this week’s issue of Science on the cloud feedback
  • clouds are important regulators of the amount of energy in and out of the climate system. Clouds both reflect sunlight back to space and trap infrared radiation and keep it from escaping to space. Changes in clouds can therefore have profound impacts on our climate.
  • A positive cloud feedback loop posits a scenario whereby an initial warming of the planet, caused, for example, by increases in greenhouse gases, causes clouds to trap more energy and lead to further warming. Such a process amplifies the direct heating by greenhouse gases. Models have been long predicted this, but testing the models has proved difficult.
  • ...8 more annotations...
  • Making the issue even more contentious, some of the more credible skeptics out there (e.g., Lindzen, Spencer) have been arguing that clouds behave quite differently from that predicted by models. In fact, they argue, clouds will stabilize the climate and prevent climate change from occurring (i.e., clouds will provide a negative feedback).
  • In my new paper, I calculate the energy trapped by clouds and observe how it varies as the climate warms and cools during El Nino-Southern Oscillation (ENSO) cycles. I find that, as the climate warms, clouds trap an additional 0.54±0.74W/m2 for every degree of warming. Thus, the cloud feedback is likely positive, but I cannot rule out a slight negative feedback.
  • while a slight negative feedback cannot be ruled out, the data do not support a negative feedback large enough to substantially cancel the well-established positive feedbacks, such as water vapor, as Lindzen and Spencer would argue.
  • I have also compared the results to climate models. Taken as a group, the models substantially reproduce the observations. This increases my confidence that the models are accurately simulating the variations of clouds with climate change.
  • Dr. Spencer is arguing that clouds are causing ENSO cycles, so the direction of causality in my analysis is incorrect and my conclusions are in error. After reading this, I initiated a cordial and useful exchange of e-mails with Dr. Spencer (you can read the full e-mail exchange here). We ultimately agreed that the fundamental disagreement between us is over what causes ENSO. Short paraphrase: Spencer: ENSO is caused by clouds. You cannot infer the response of clouds to surface temperature in such a situation. Dessler: ENSO is not caused by clouds, but is driven by internal dynamics of the ocean-atmosphere system. Clouds may amplify the warming, and that’s the cloud feedback I’m trying to measure.
  • My position is the mainstream one, backed up by decades of research. This mainstream theory is quite successful at simulating almost all of the aspects of ENSO. Dr. Spencer, on the other hand, is as far out of the mainstream when it comes to ENSO as he is when it comes to climate change. He is advancing here a completely new and untested theory of ENSO — based on just one figure in one of his papers (and, as I told him in one of our e-mails, there are other interpretations of those data that do not agree with his interpretation). Thus, the burden of proof is Dr. Spencer to show that his theory of causality during ENSO is correct. He is, at present, far from meeting that burden. And until Dr. Spencer satisfies this burden, I don’t think anyone can take his criticisms seriously.
  • It’s also worth noting that the picture I’m painting of our disagreement (and backed up by the e-mail exchange linked above) is quite different from the picture provided by Dr. Spencer on his blog. His blog is full of conspiracies and purposeful suppression of the truth. In particular, he accuses me of ignoring his work. But as you can see, I have not ignored it — I have dismissed it because I think it has no merit. That’s quite different. I would also like to respond to his accusation that the timing of the paper is somehow connected to the IPCC’s meeting in Cancun. I can assure everyone that no one pressured me in any aspect of the publication of this paper. As Dr. Spencer knows well, authors have no control over when a paper ultimately gets published. And as far as my interest in influencing the policy debate goes, I’ll just say that I’m in College Station this week, while Dr. Spencer is in Cancun. In fact, Dr. Spencer had a press conference in Cancun — about my paper. I didn’t have a press conference about my paper. Draw your own conclusion.
  • This is but another example of how climate scientists are being played by the denialists. You attempted to discuss the issue with Spencer as if he were only doing science. But he is not. He is doing science and politics, and he has no compunction about sandbagging you. There is no gain to you in trying to deal with people like Spencer and Lindzen as colleagues. They are not trustworthy.

Skepticblog » Further Thoughts on Atheism - 0 views

  • Even before I started writing Evolution: How We and All Living Things Came to Be I knew that it would very briefly mention religion, make a mild assertion that religious questions are out of scope for science, and move on. I knew this was likely to provoke blow-back from some in the atheist community, and I knew mentioning that blow-back in my recent post “The Standard Pablum — Science and Atheism” would generate more.
  • Still, I was surprised by the quantity of the responses to the blog post (208 comments as of this moment, many of them substantial letters), and also by the fierceness of some of those responses. For example, according to one poster, “you not only pandered, you lied. And even if you weren’t lying, you lied.” (Several took up this “lying” theme.) Another, disappointed that my children’s book does not tell a general youth audience to look to “secular humanism for guidance,” declared  that “I’d have to tear out that page if I bought the book.”
  • I don’t mean to suggest that there are not points of legitimate disagreement in the mix — there are, many of them stated powerfully. There are also statements of support, vigorous debate, and (for me at least) a good deal of food for thought. I invite anyone to browse the thread, although I’d urge you to skim some of it. (The internet is after all a hyperbole-generating machine.)

  • do try to distinguish between my work as a science writer and skeptical activist on the one hand, and my personal opinions about religion and humanism on the other.
  • Atheism is a practical handicap for science outreach. I’m not naive about this, but I’m not cynical either. I’m a writer. I’m in the business of communicating ideas about science, not throwing up roadblocks and distractions. It’s good communication to keep things as clear, focused, and on-topic as possible.
  • Atheism is divisive for the skeptical community, and it distracts us from our core mandate. I was blunt about this in my 2007 essay “Where Do We Go From Here?”, writing, I’m both an atheist and a secular humanist, but it is clear to me that atheism is an albatross for the skeptical movement. It divides us, it distracts us, and it marginalizes us. Frankly, we can’t afford that. We need all the help we can get.
  • In What Do I Do Next? I urged skeptics to remember that there are many other skeptics who do hold or identify with some religion. Indeed, the modern skeptical movement is built partly on the work of people of faith (including giants like Harry Houdini and Martin Gardner). You don’t, after all, have to be against god to be against fraud.
  • In my Skeptical Inquirer article “The Paradoxical Future of Skepticism” I argued that skeptics must set aside the conceit that our goal is a cultural revolution or the dawning of a new Enlightenment. … When we focus on that distant, receding, and perhaps illusory goal, we fail to see the practical good we can do, the harm-reduction opportunities right in front of us. The long view subverts our understanding of the scale and hazard of paranormal beliefs, leading to sentiments that the paranormal is “trivial” or “played out.” By contrast, the immediate, local, human view — the view that asks “Will this help someone?” — sees obvious opportunities for every local group and grassroots skeptic to make a meaningful difference.
  • This practical argument, that skepticism can get more done if we keep our mandate tight and avoid alienating our best friends, seems to me an important one. Even so, it is not my main reason for arguing that atheism and skepticism are different projects.
  • In my opinion, Metaphysics and ethics are out of scope for science — and therefore out of scope for skepticism. This is by far the most important reason I set aside my own atheism when I put on my “skeptic” hat. It’s not that I don’t think atheism is rational — I do. That’s why I’m an atheist. But I know that I cannot claim scientific authority for a conclusion that science cannot test, confirm, or disprove. And so, I restrict myself as much as possible, in my role as a skeptic and science writer, to investigable claims. I’ve become a cheerleader for this “testable claims” criterion (and I’ll discuss it further in future posts) but it’s not a new or radical constriction of the scope of skepticism. It’s the traditional position occupied by skeptical organizations for decades.
  • In much of the commentary, I see an assumption that I must not really believe that testable paranormal and pseudoscientific claims (“I can read minds”) are different in kind from the untestable claims we often find at the core of religion (“god exists”). I acknowledge that many smart people disagree on this point, but I assure you that this is indeed what I think.
  • I’d like to call out one blogger’s response to my “Standard Pablum” post. The author certainly disagrees with me (we’ve discussed the topic often on Twitter), but I thank him for describing my position fairly: From what I’ve read of Daniel’s writings before, this seems to be a very consistent position that he has always maintained, not a new one he adopted for the book release. It appears to me that when Daniel says that science has nothing to say about religion, he really means it. I have nothing to say to that. It also appears to me that when he says skepticism is a “different project than atheism” he also means it.

Climate Emails Stoke Debate - WSJ.com - 0 views

  • The scientific community is buzzing over thousands of emails and documents -- posted on the Internet last week after being hacked from a prominent climate-change research center -- that some say raise ethical questions about a group of scientists who contend humans are responsible for global warming.
  • Some emails also refer to efforts by scientists who believe man is causing global warming to exclude contrary views from important scientific publications.
  • "This is what everyone feared. Over the years, it has become increasingly difficult for anyone who does not view global warming as an end-of-the-world issue to publish papers. This isn't questionable practice, this is unethical."

  • "The selective publication of some stolen emails and other papers taken out of context is mischievous and cannot be considered a genuine attempt to engage with this issue in a responsible way," the university said.
  • A partial review of the hacked material suggests there was an effort at East Anglia, which houses an important center of global climate research, to shut out dissenters and their points of view. In the emails, which date to 1996, researchers in the U.S. and the U.K. repeatedly take issue with climate research at odds with their own findings. In some cases, they discuss ways to rebut what they call "disinformation" using new articles in scientific journals or popular Web sites. The emails include discussions of apparent efforts to make sure that reports from the Intergovernmental Panel on Climate Change, a United Nations group that monitors climate science, include their own views and exclude others. In addition, emails show that climate scientists declined to make their data available to scientists whose views they disagreed with.
  • Phil Jones, the director of the East Anglia climate center, suggested to climate scientist Michael Mann of Penn State University that skeptics' research was unwelcome: We "will keep them out somehow -- even if we have to redefine what the peer-review literature is!"
  • John Christy, a scientist at the University of Alabama at Huntsville attacked in the emails for asking that an IPCC report include dissenting viewpoints, said, "It's disconcerting to realize that legislative actions this nation is preparing to take, and which will cost trillions of dollars, are based upon a view of climate that has not been completely scientifically tested."
