Unsealed Documents Raise Questions on Monsanto Weed Killer - The New York Times - 0 views

  • The court documents included Monsanto’s internal emails and email traffic between the company and federal regulators. The records suggested that Monsanto had ghostwritten research that was later attributed to academics and indicated that a senior official at the Environmental Protection Agency had worked to quash a review of Roundup’s main ingredient, glyphosate, that was to have been conducted by the United States Department of Health and Human Services.
  • The safety of glyphosate is not settled science.
  • In a statement, Monsanto said, “Glyphosate is not a carcinogen.”

  • Monsanto also rebutted suggestions that the disclosures highlighted concerns that the academic research it underwrites is compromised.
  • they could ghostwrite research on glyphosate by hiring academics to put their names on papers that were actually written by Monsanto.
  • The issue of glyphosate’s safety is not a trivial one for Americans. Over the last two decades, Monsanto has genetically re-engineered corn, soybeans and cotton so it is much easier to spray them with the weed killer, and some 220 million pounds of glyphosate were used in 2015 in the United States.

    This news shows that there are a lot of cases that companies use science as a shield to convince people that their product is safe and good. Honesty is scientific papers has always been an important issue when we talk about the reliability of those papers. As we discussed in TOK, science is more like a social project that involves a lot of people and all human works are more or less biased and subjective. Now, science is intertwined with benefit and economics so the issue become much more complicated. I think we should identify the sources of the paper before citing any word from the paper because who write the paper is a big factor of which side the paper is standing. --Sissi (3/14/2017)

How have changes to publishing affected scientists? | Julie McDougall-Waters | Science ... - 0 views

  • That was the purpose of a recent oral history event at the Royal Society, involving four senior scientists who began their careers in the 1960s and 1970s. Rather than simply reminiscing, they were asked to recall their publishing experiences in scientific periodicals over the last fifty years. How have things changed since they published their first paper?
  • It became clear that the hierarchy of journals has changed over the last fifty years, and the pressure to publish in those considered to have the highest impact has increased considerably, partly a result of the increased volume of data being produced and the need for readers to filter relevant information from the copious amounts of less pertinent stuff available.
  • What have also changed are the technologies available to write a paper. Frith related the process she went through in writing her first paper: “I wrote my papers by long hand and then typed them myself.” Writing a biological paper before computers is one thing, but Ashmore remembered the problems of producing mathematical formulae in a typed manuscript, explaining that “you wrote the paper and probably took it along to somebody to be typed… And then it came back with spaces where you had to write in the equations.”

  • Another change that interested the panellists was the increased number of collaborative and multiple authored papers now submitted to journals, which led them to think about the ethics of acknowledgement. In Meurig Thomas’s view the author is, simply, “the person that primarily thinks about the experiment, plans it, and writes it. I can sleep more comfortably at night this way. If I claim to be a senior author, I have to write it and I have to concoct what the experiment was, and defend it.” Chaloner suggested that authorship has grown “because of the pressure for people to have publications in their names”, with an “agreement to let you come onto this paper and I’ll get on yours next time”. Frith referred to this as “gaming”.
  • Despite all of the technological developments in the last fifty years, there has been no quick or easy response to questions over refereeing, and the event ended with the feeling that although there is no doubt technology has transformed the way science is communicated, its effect has not invariably simplified the process.

    As we learned in TOK, science is full of uncertainties. And in this article, the author suggests that even the publication of science paper is full of flaws. But the general population often cited science source that's in support of them. However, science findings are full of faults and the possibility is very high for the scientists to make a false claim. Sometimes, not the errors in experiments, but the fabrication of data lead to false scientific papers. And also, there are a lot of patterns behind the publication of false scientific papers.

Rise in Scientific Journal Retractions Prompts Calls for Reform - NYTimes.com - 1 views

  • before long they reached a troubling conclusion: not only that retractions were rising at an alarming rate, but that retractions were just a manifestation of a much more profound problem — “a symptom of a dysfunctional scientific climate,” as Dr. Fang put it.
  • he feared that science had turned into a winner-take-all game with perverse incentives that lead scientists to cut corners and, in some cases, commit acts of misconduct.
  • Members of the committee agreed with their assessment. “I think this is really coming to a head,” said Dr. Roberta B. Ness, dean of the University of Texas School of Public Health. And Dr. David Korn of Harvard Medical School agreed that “there are problems all through the system.”

  • science has changed in some worrying ways in recent decades — especially biomedical research, which consumes a larger and larger share of government science spending.
  • the journal Nature reported that published retractions had increased tenfold over the past decade, while the number of published papers had increased by just 44 percent.
  • because journals are now online, bad papers are simply reaching a wider audience, making it more likely that errors will be spotted.
  • The National Institutes of Health accepts a much lower percentage of grant applications today than in earlier decades. At the same time, many universities expect scientists to draw an increasing part of their salaries from grants, and these pressures have influenced how scientists are promoted.
  • Dr. Fang and Dr. Casadevall looked at the rate of retractions in 17 journals from 2001 to 2010 and compared it with the journals’ “impact factor,” a score based on how often their papers are cited by scientists. The higher a journal’s impact factor, the two editors found, the higher its retraction rate.
  • Each year, every laboratory produces a new crop of Ph.D.’s, who must compete for a small number of jobs, and the competition is getting fiercer. In 1973, more than half of biologists had a tenure-track job within six years of getting a Ph.D. By 2006 the figure was down to 15 percent.

  • “What people do is they count papers, and they look at the prestige of the journal in which the research is published, and they see how may grant dollars scientists have, and if they don’t have funding, they don’t get promoted,” Dr. Fang said. “It’s not about the quality of the research.”
  • Dr. Ness likens scientists today to small-business owners, rather than people trying to satisfy their curiosity about how the world works. “You’re marketing and selling to other scientists,” she said. “To the degree you can market and sell your products better, you’re creating the revenue stream to fund your enterprise.”
  • Universities want to attract successful scientists, and so they have erected a glut of science buildings, Dr. Stephan said. Some universities have gone into debt, betting that the flow of grant money will eventually pay off the loans.
  • “You can’t afford to fail, to have your hypothesis disproven,” Dr. Fang said. “It’s a small minority of scientists who engage in frank misconduct. It’s a much more insidious thing that you feel compelled to put the best face on everything.”

  • They would also move away from the winner-take-all system, in which grants are concentrated among a small fraction of scientists. One way to do that may be to put a cap on the grants any one lab can receive.
  • Such a shift would require scientists to surrender some of their most cherished practices — the priority rule, for example, which gives all the credit for a scientific discovery to whoever publishes results first.
  • To ease such cutthroat competition, the two editors would also change the rules for scientific prizes and would have universities take collaboration into account when they decide on promotions.
  • Even scientists who are sympathetic to the idea of fundamental change are skeptical that it will happen any time soon. “I don’t think they have much chance of changing what they’re talking about,” said Dr. Korn, of Harvard.
  • “When our generation goes away, where is the new generation going to be?” he asked. “All the scientists I know are so anxious about their funding that they don’t make inspiring role models. I heard it from my own kids, who went into art and music respectively. They said, ‘You know, we see you, and you don’t look very happy.’ ”

Study Finds Misconduct Widespread in Retracted Scientific Papers - NYTimes.com - 0 views

Doubts about Johns Hopkins research have gone unanswered, scientist says - The Washingt... - 0 views

  • Over and over, Daniel Yuan, a medical doctor and statistician, couldn’t understand the results coming out of the lab, a prestigious facility at Johns Hopkins Medical School funded by millions from the National Institutes of Health.He raised questions with the lab’s director. He reran the calculations on his own. He looked askance at the articles arising from the research, which were published in distinguished journals. He told his colleagues: This doesn’t make sense.“At first, it was like, ‘Okay — but I don’t really see it,’ ” Yuan recalled. “Then it started to smell bad.”
  • The passions of scientific debate are probably not much different from those that drive achievement in other fields, so a tragic, even deadly dispute might not be surprising.But science, creeping ahead experiment by experiment, paper by paper, depends also on institutions investigating errors and correcting them if need be, especially if they are made in its most respected journals.If the apparent suicide and Yuan’s detailed complaints provoked second thoughts about the Nature paper, though, there were scant signs of it.The journal initially showed interest in publishing Yuan’s criticism and told him that a correction was “probably” going to be written, according to e-mail rec­ords. That was almost six months ago. The paper has not been corrected.The university had already fired Yuan in December 2011, after 10 years at the lab. He had been raising questions about the research for years. He was escorted from his desk by two security guards.
  • Last year, research published in the Proceedings of the National Academy of Sciences found that the percentage of scientific articles retracted because of fraud had increased tenfold since 1975. The same analysis reviewed more than 2,000 retracted biomedical papers and found that 67 percent of the retractions were attributable to misconduct, mainly fraud or suspected fraud.

  • Fang said retractions may be rising because it is simply easier to cheat in an era of digital images, which can be easily manipulated. But he said the increase is caused at least in part by the growing competition for publication and for NIH grant money.He noted that in the 1960s, about two out of three NIH grant requests were funded; today, the success rate for applicants for research funding is about one in five. At the same time, getting work published in the most esteemed journals, such as Nature, has become a “fetish” for some scientists, Fang said.
  • many observers note that universities and journals, while sometimes agreeable to admitting small mistakes, are at times loath to reveal that the essence of published work was simply wrong.“The reader of scientific information is at the mercy of the scientific institution to investigate or not,” said Adam Marcus, who with Ivan Oransky founded the blog Retraction Watch in 2010. In this case, Marcus said, “if Hopkins doesn’t want to move, we may not find out what is happening for two or three years.”
  • The trouble is that a delayed response — or none at all — leaves other scientists to build upon shaky work. Fang said he has talked to researchers who have lost months by relying on results that proved impossible to reproduce.Moreover, as Marcus and Oransky have noted, much of the research is funded by taxpayers. Yet when retractions are done, they are done quietly and “live in obscurity,” meaning taxpayers are unlikely to find out that their money may have been wasted.

Clouds' Effect on Climate Change Is Last Bastion for Dissenters - NYTimes.com - 0 views

  • For decades, a small group of scientific dissenters has been trying to shoot holes in the prevailing science of climate change, offering one reason after another why the outlook simply must be wrong.

But the worst possible place to resolve such issues is the political arena." Alexander Flax, Potomac, MD Read Full Comment » Post a Comment » Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97 percent of working climate scientists now see global warming as a serious risk.
  • They acknowledge that the human release of greenhouse gases will cause the planet to warm. But they assert that clouds — which can either warm or cool the earth, depending on the type and location — will shift in such a way as to counter much of the expected temperature rise and preserve the equable climate on which civilization depends.
  • At gatherings of climate change skeptics on both sides of the Atlantic, Dr. Lindzen has been treated as a star. During a debate in Australia over carbon taxes, his work was cited repeatedly. When he appears at conferences of the Heartland Institute, the primary American organization pushing climate change skepticism, he is greeted by thunderous applause.

  • His idea has drawn withering criticism from other scientists, who cite errors in his papers and say proof is lacking. Enough evidence is already in hand, they say, to rule out the powerful cooling effect from clouds that would be needed to offset the increase of greenhouse gases.
  • “If you listen to the credible climate skeptics, they’ve really pushed all their chips onto clouds.”
  • Dr. Lindzen is “feeding upon an audience that wants to hear a certain message, and wants to hear it put forth by people with enough scientific reputation that it can be sustained for a while, even if it’s wrong science,” said Christopher S. Bretherton, an atmospheric researcher at the University of Washington. “I don’t think it’s intellectually honest at all.”
  • With climate policy nearly paralyzed in the United States, many other governments have also declined to take action, and worldwide emissions of greenhouse gases are soaring.
  • The most elaborate computer programs have agreed on a broad conclusion: clouds are not likely to change enough to offset the bulk of the human-caused warming. Some of the analyses predict that clouds could actually amplify the warming trend sharply through several mechanisms, including a reduction of some of the low clouds that reflect a lot of sunlight back to space. Other computer analyses foresee a largely neutral effect. The result is a big spread in forecasts of future temperature, one that scientists have not been able to narrow much in 30 years of effort.
  • The earth’s surface has already warmed about 1.4 degrees Fahrenheit since the Industrial Revolution, most of that in the last 40 years. Modest as it sounds, it is an average for the whole planet, representing an enormous addition of heat. An even larger amount is being absorbed by the oceans. The increase has caused some of the world’s land ice to melt and the oceans to rise.
  • Even in the low projection, many scientists say, the damage could be substantial. In the high projection, some polar regions could heat up by 20 or 25 degrees Fahrenheit — more than enough, over centuries or longer, to melt the Greenland ice sheet, raising sea level by a catastrophic 20 feet or more. Vast changes in  rainfall, heat waves and other weather patterns would most likely accompany such a large warming. “The big damages come if the climate sensitivity to greenhouse gases turns out to be high,” said Raymond T. Pierrehumbert, a climate scientist at the University of Chicago. “Then it’s not a bullet headed at us, but a thermonuclear warhead.”
  • But the problem of how clouds will behave in a future climate is not yet solved — making the unheralded field of cloud research one of the most important pursuits of modern science.
  • for more than a decade, Dr. Lindzen has said that when surface temperature increases, the columns of moist air rising in the tropics will rain out more of their moisture, leaving less available to be thrown off as ice, which forms the thin, high clouds known as cirrus. Just like greenhouse gases, these cirrus clouds act to reduce the cooling of the earth, and a decrease of them would counteract the increase of greenhouse gases. Dr. Lindzen calls his mechanism the iris effect, after the iris of the eye, which opens at night to let in more light. In this case, the earth’s “iris” of high clouds would be opening to let more heat escape.
  • Dr. Lindzen acknowledged that the 2009 paper contained “some stupid mistakes” in his handling of the satellite data. “It was just embarrassing,” he said in an interview. “The technical details of satellite measurements are really sort of grotesque.” Last year, he tried offering more evidence for his case, but after reviewers for a prestigious American journal criticized the paper, Dr. Lindzen published it in a little-known Korean journal. Dr. Lindzen blames groupthink among climate scientists for his publication difficulties, saying the majority is determined to suppress any dissenting views. They, in turn, contend that he routinely misrepresents the work of other researchers.
  • Ultimately, as the climate continues warming and more data accumulate, it will become obvious how clouds are reacting. But that could take decades, scientists say, and if the answer turns out to be that catastrophe looms, it would most likely be too late. By then, they say, the atmosphere would contain so much carbon dioxide as to make a substantial warming inevitable, and the gas would not return to a normal level for thousands of years.
  • In his Congressional appearances, speeches and popular writings, Dr. Lindzen offers little hint of how thin the published science supporting his position is. Instead, starting from his disputed iris mechanism, he makes what many of his colleagues see as an unwarranted leap of logic, professing near-certainty that climate change is not a problem society needs to worry about.
  • “Even if there were no political implications, it just seems deeply unprofessional and irresponsible to look at this and say, ‘We’re sure it’s not a problem,’ ” said Kerry A. Emanuel, another M.I.T. scientist. “It’s a special kind of risk, because it’s a risk to the collective civilization.”

The Technium: When Hard Books Disappear - 0 views

  • We are in a special moment that will not last beyond the end of this century: Paper books are plentiful. They are cheap and everywhere, from airports to drug stores to libraries to bookstores to the shelves of millions of homes. There has never been a better time to be a lover of paper books. But very rapidly the production of paper books will essentially cease, and the collections in homes will dwindle, and even local libraries will not be supported to house books -- particularly popular titles. Rare books will collect in a few rare book libraries, and for the most part common paper books archives will become uncommon. It seems hard to believe now, but within a few generations, seeing a actual paper book will be as rare for most people as seeing an actual lion.

Deeper Ties to Corporate Cash for Doubtful Climate Researcher - NYTimes.com - 1 views

  • For years, politicians wanting to block legislation on climate change have bolstered their arguments by pointing to the work of a handful of scientists who claim that greenhouse gases pose little risk to humanity.
  • One of the names they invoke most often is Wei-Hock Soon, known as Willie, a scientist at the Harvard-Smithsonian Center for Astrophysics who claims that variations in the sun’s energy can largely explain recent global warming.
  • He has accepted more than $1.2 million in money from the fossil-fuel industry over the last decade while failing to disclose that conflict of interest in most of his scientific papers. At least 11 papers he has published since 2008 omitted such a disclosure, and in at least eight of those cases, he appears to have violated ethical guidelines of the journals that published his work.
  • ...11 more annotations...
  • Historians and sociologists of science say that since the tobacco wars of the 1960s, corporations trying to block legislation that hurts their interests have employed a strategy of creating the appearance of scientific doubt, usually with the help of ostensibly independent researchers who accept industry funding.
  • “The whole doubt-mongering strategy relies on creating the impression of scientific debate,” said Naomi Oreskes, a historian of science at Harvard University and the co-author of “Merchants of Doubt,” a book about such campaigns. “Willie Soon is playing a role in a certain kind of political theater.”
  • Environmentalists have long questioned Dr. Soon’s work, and his acceptance of funding from the fossil-fuel industry was previously known. But the full extent of the links was not; the documents show that corporate contributions were tied to specific papers and were not disclosed, as required by modern standards of publishing.
  • “What it shows is the continuation of a long-term campaign by specific fossil-fuel companies and interests to undermine the scientific consensus on climate change,” said Kert Davies, executive director of the Climate Investigations Center, a group funded by foundations seeking to limit the risks of climate change.
  • Many experts in the field say that Dr. Soon uses out-of-date data, publishes spurious correlations between solar output and climate indicators, and does not take account of the evidence implicating emissions from human behavior in climate change.
  • Though often described on conservative news programs as a “Harvard astrophysicist,” Dr. Soon is not an astrophysicist and has never been employed by Harvard. He is a part-time employee of the Smithsonian Institution with a doctoral degree in aerospace engineering. He has received little federal research money over the past decade and is thus responsible for bringing in his own funds, including his salary.
  • Though he has little formal training in climatology, Dr. Soon has for years published papers trying to show that variations in the sun’s energy can explain most recent global warming. His thesis is that human activity has played a relatively small role in causing climate change.
  • As the oil-industry contributions fell, Dr. Soon started receiving hundreds of thousands of dollars through DonorsTrust, an organization based in Alexandria, Va., that accepts money from donors who wish to remain anonymous, then funnels it to various conservative causes.
  • Gavin A. Schmidt, head of the Goddard Institute for Space Studies in Manhattan, a NASA division that studies climate change, said that the sun had probably accounted for no more than 10 percent of recent global warming and that greenhouse gases produced by human activity explained most of it.“The science that Willie Soon does is almost pointless,” Dr. Schmidt said.
  • Dr. Soon has found a warm welcome among politicians in Washington and state capitals who try to block climate action. United States Senator James M. Inhofe, an Oklahoma Republican who claims that climate change is a global scientific hoax, has repeatedly cited Dr. Soon’s work over the years.
  • Dr. Oreskes, the Harvard science historian, said that academic institutions and scientific journals had been too lax in recent decades in ferreting out dubious research created to serve a corporate agenda.

Naomi Oreskes, a Lightning Rod in a Changing Climate - The New York Times - 0 views

  • Dr. Oreskes is fast becoming one of the biggest names in climate science — not as a climatologist, but as a defender who uses the tools of historical scholarship to counter what she sees as ideologically motivated attacks on the field.
  • Formally, she is a historian of science
  • Dr. Oreskes’s approach has been to dig deeply into the history of climate change denial, documenting its links to other episodes in which critics challenged a developing scientific consensus.
  • ...20 more annotations...
  • Her core discovery, made with a co-author, Erik M. Conway, was twofold. They reported that dubious tactics had been used over decades to cast doubt on scientific findings relating to subjects like acid rain, the ozone shield, tobacco smoke and climate change. And most surprisingly, in each case, the tactics were employed by the same group of people.
  • The central players were serious scientists who had major career triumphs during the Cold War, but in subsequent years apparently came to equate environmentalism with socialism, and government regulation with tyranny.
  • In a 2010 book, Dr. Oreskes and Dr. Conway called these men “Merchants of Doubt,” and this spring the book became a documentary film, by Robert Kenner. At the heart of both works is a description of methods that were honed by the tobacco industry in the 1960s and have since been employed to cast doubt on just about any science being cited to support new government regulations.
  • Dr. Oreskes, the more visible and vocal of the “Merchants” authors, has been threatened with lawsuits and vilified on conservative websites, and routinely gets hate mail calling her a communist or worse.
  • She established her career as a historian with a book-length study examining the role of dissent in the scientific method. As she put it a few months ago to an audience at Indiana University, she wanted to wrestle with this question: “How do you distinguish a maverick from a crank?”
  • Dr. Oreskes found that Wegener had been treated badly, particularly by American geologists. But he did not abandon his faith in the scientific method. He kept publishing until his death in 1930, trying to convince fellow scientists of his position, and was finally vindicated three decades later by oceanographic research conducted during the Cold War.
  • As she completed that study, Dr. Oreskes sought to understand how science was affected not only by the Cold War but by its end. In particular, she started wondering about climate science. Global warming had seemed to rise as an important issue around the time the Iron Curtain came down. Was this just a way for scientists to scare up research money that would no longer be coming their way through military channels?
  • the widespread public impression was that scientists were still divided over whether humans were primarily responsible for the warming of the planet. But how sharp was the split, she wondered?
  • She decided to do something no climate scientist had thought to do: count the published scientific papers. Pulling 928 of them, she was startled to find that not one dissented from the basic findings that warming was underway and human activity was the main reason.
  • She published that finding in a short paper in the journal Science in 2004, and the reaction was electric. Advocates of climate action seized on it as proof of a level of scientific consensus that most of them had not fully perceived. Just as suddenly, Dr. Oreskes found herself under political attack.
  • Some of the voices criticizing her — scientists like Dr. Singer and groups like the George C. Marshall Institute in Washington — were barely known to her at the time, Dr. Oreskes said in an interview. Just who were they?
  • It did not take them long to document that this group, which included prominent Cold War scientists, had been attacking environmental research for decades, challenging the science of the ozone layer and acid rain, even the finding that breathing secondhand tobacco smoke was harmful. Trying to undermine climate science was simply the latest project.
  • Dr. Oreskes and Dr. Conway came to believe that the attacks were patterned on the strategy employed by the tobacco industry when evidence of health risks first emerged. Documents pried loose by lawyers showed that the industry had paid certain scientists to contrive dubious research, had intimidated reputable scientists, and had cherry-picked evidence to present a misleading pictur
  • The tobacco industry had used these tactics in defense of profits. But Dr. Oreskes and Dr. Conway wrote that the so-called merchants of doubt had adopted them for a deep ideological reason: contempt for government regulation. The insight gave climate scientists a new way of understanding the politics that had engulfed their field.
  • Following Dr. Oreskes’s cue, researchers have in recent years developed a cottage industry of counting scientific papers and polling scientists. The results typically show that about 97 percent of working climate scientists accept that global warming is happening, that humans are largely responsible, and that the situation poses long-term risks, though the severity of those risks is not entirely clear. That wave of evidence has prompted many national news organizations to stop portraying the field as split evenly between scientists who are convinced and unconvinced.
  • Dr. Oreskes’s critics have taken delight in searching out errors in her books and other writings, prompting her to post several corrections. They have generally been minor, though, like describing a pH of six as neutral, when the correct number is seven. Dr. Oreskes described that as a typographical error.
  • In the leaked emails, Dr. Singer told a group of his fellow climate change denialists that he felt that Dr. Oreskes and Dr. Conway had libeled him. But in an interview, when pressed for specific errors in the book that might constitute libel, he listed none. Nor did he provide such a list in response to a follow-up email request.
  • However much she might be hated by climate change denialists, Dr. Oreskes is often welcomed on college campuses these days. She usually outlines the decades of research supporting the idea that human emissions pose serious risks.
  • “One of the things that should always be asked about scientific evidence is, how old is it?” Dr. Oreskes said. “It’s like wine. If the science about climate change were only a few years old, I’d be a skeptic, too.”
  • Dr. Oreskes and Dr. Conway keep looking for ways to reach new audiences. Last year, they published a short work of science fiction, written as a historical essay from the distant future. “The Collapse of Western Civilization: A View From the Future” argues that conservatives, by fighting sensible action to cope with the climate crisis, are essentially guaranteeing the long-term outcome they fear, a huge expansion of government.

Human engineering | New Philosopher - 0 views

  • You know the situation is getting desperate when three bioethicists propose genetically modifying humans to reduce our environmental impact. In a bizarre paper titled ‘Human engineering and climate change’, Matthew Liao, Anders Sandberg and Rebecca Roache argue we should seriously consider technologies to engineer human bodies to reduce carbon emissions.
  • The paper, to be published in a respectable journal, is beyond satire and its only likely effect is to bring the philosophy profession into disrepute. Philosophy, it seems, does not have a ‘laugh test’ for filtering out whacky proposals. So why stop at cat’s eyes and midget babies? Why not genetically modify people to make them white in order to cool the Earth by increasing its reflectivity?

  • But perhaps the paper by Liao, Sandberg and Roache will turn out to be a prank played on the journal, like the Sokal hoax, named after the physicist whose paper deploying post-modern gobbledegook to show that “quantum gravity is a social and linguistic construct” was published in a cultural studies journal.
  • It’s easy to imagine academics sitting around swapping the most outrageous solutions to climate change and then daring one another to have them published. I hope this will turn out to be the case. In the meantime I cringe at the thought of what the long-dead giants of Western philosophy would make of their discipline’s response to the climate crisis.

  • How should we choose among these dueling, high-profile nutritional findings? Ioannidis suggests a simple approach: ignore them all.
  • even if a study managed to highlight a genuine health connection to some nutrient, you’re unlikely to benefit much from taking more of it, because we consume thousands of nutrients that act together as a sort of network, and changing intake of just one of them is bound to cause ripples throughout the network that are far too complex for these studies to detect, and that may be as likely to harm you as help you

  • studies usually detect only modest effects that merely tend to whittle your chances of succumbing to a particular disease from small to somewhat smaller
  • The odds that anything useful will survive from any of these studies are poor,” says Ioannidis—dismissing in a breath a good chunk of the research into which we sink about $100 billion a year in the United States alone.
  • nutritional studies aren’t the worst. Drug studies have the added corruptive force of financial conflict of interest.
  • 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.
  • Nature, the grande dame of science journals, stated in a 2006 editorial, “Scientists understand that peer review per se provides only a minimal assurance of quality, and that the public conception of peer review as a stamp of authentication is far from the truth.
  • 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.
  • even for medicine’s most influential studies, the evidence sometimes remains surprisingly narrow. Of those 45 super-cited studies that Ioannidis focused on, 11 had never been retested
  • even when a research error is outed, it typically persists for years or even decades.
  • much, perhaps even most, of what doctors do has never been formally put to the test in credible studies, given that the need to do so became obvious to the field only in the 1990s
  • Other meta-research experts have confirmed that similar issues distort research in all fields of science, from physics to economics (where the highly regarded economists J. Bradford DeLong and Kevin Lang once showed how a remarkably consistent paucity of strong evidence in published economics studies made it unlikely that any of them were right
  • His PLoS Medicine paper is the most downloaded in the journal’s history, and it’s not even Ioannidis’s most-cited work
  • while his fellow researchers seem to be getting the message, he hasn’t necessarily forced anyone to do a better job. He fears he won’t in the end have done much to improve anyone’s health. “There may not be fierce objections to what I’m saying,” he explains. “But it’s difficult to change the way that everyday doctors, patients, and healthy people think and behave.”
  • “Usually what happens is that the doctor will ask for a suite of biochemical tests—liver fat, pancreas function, and so on,” she tells me. “The tests could turn up something, but they’re probably irrelevant. Just having a good talk with the patient and getting a close history is much more likely to tell me what’s wrong.” Of course, the doctors have all been trained to order these tests, she notes, and doing so is a lot quicker than a long bedside chat. They’re also trained to ply the patient with whatever drugs might help whack any errant test numbers back into line.
  • What they’re not trained to do is to go back and look at the research papers that helped make these drugs the standard of care. “When you look the papers up, you often find the drugs didn’t even work better than a placebo. And no one tested how they worked in combination with the other drugs,” she says. “Just taking the patient off everything can improve their health right away.” But not only is checking out the research another time-consuming task, patients often don’t even like it when they’re taken off their drugs, she explains; they find their prescriptions reassuring.
  • Already feeling that they’re fighting to keep patients from turning to alternative medical treatments such as homeopathy, or misdiagnosing themselves on the Internet, or simply neglecting medical treatment altogether, many researchers and physicians aren’t eager to provide even more reason to be skeptical of what doctors do—not to mention how public disenchantment with medicine could affect research funding.
  • We could solve much of the wrongness problem, Ioannidis says, if the world simply stopped expecting scientists to be right. That’s because being 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
  • Science is a noble endeavor, but it’s also a low-yield endeavor,” he says. “I’m not sure that more than a very small percentage of medical research is ever likely to lead to major improvements in clinical outcomes and quality of life. We should be very comfortable with that fact.”

Noted Dutch Psychologist, Stapel, Accused of Research Fraud - NYTimes.com - 0 views

  • A well-known psychologist in the Netherlands whose work has been published widely in professional journals falsified data and made up entire experiments, an investigating committee has found
  • Experts say the case exposes deep flaws in the way science is done in a field, psychology, that has only recently earned a fragile respectability.
  • In recent years, psychologists have reported a raft of findings on race biases, brain imaging and even extrasensory perception that have not stood up to scrutiny. Outright fraud may be rare, these experts say, but they contend that Dr. Stapel took advantage of a system that allows researchers to operate in near secrecy and massage data to find what they want to find, without much fear of being challenged.
  • ...8 more annotations...
  • “The big problem is that the culture is such that researchers spin their work in a way that tells a prettier story than what they really found,” said Jonathan Schooler, a psychologist at the University of California, Santa Barbara. “It’s almost like everyone is on steroids, and to compete you have to take steroids as well.”
  • Dr. Stapel published papers on the effect of power on hypocrisy, on racial stereotyping and on how advertisements affect how people view themselves. Many of his findings appeared in newspapers around the world, including The New York Times, which reported in December on his study about advertising and identity.
  • Dr. Stapel was able to operate for so long, the committee said, in large measure because he was “lord of the data,” the only person who saw the experimental evidence that had been gathered (or fabricated). This is a widespread problem in psychology, said Jelte M. Wicherts, a psychologist at the University of Amsterdam. In a recent survey, two-thirds of Dutch research psychologists said they did not make their raw data available for other researchers to see. “This is in violation of ethical rules established in the field,” Dr. Wicherts said.
  • In a survey of more than 2,000 American psychologists scheduled to be published this year, Leslie John of Harvard Business School and two colleagues found that 70 percent had acknowledged, anonymously, to cutting some corners in reporting data. About a third said they had reported an unexpected finding as predicted from the start, and about 1 percent admitted to falsifying data.
  • Also common is a self-serving statistical sloppiness. In an analysis published this year, Dr. Wicherts and Marjan Bakker, also at the University of Amsterdam, searched a random sample of 281 psychology papers for statistical errors. They found that about half of the papers in high-end journals contained some statistical error, and that about 15 percent of all papers had at least one error tha
  • t changed a reported finding — almost always in opposition to the authors’ hypothesis.
  • an analysis of 49 studies appearing Wednesday in the journal PLoS One, by Dr. Wicherts, Dr. Bakker and Dylan Molenaar, found that the more reluctant that scientists were to share their data, the more likely that evidence contradicted their reported findings.
  • “We know the general tendency of humans to draw the conclusions they want to draw — there’s a different threshold,” said Joseph P. Simmons, a psychologist at the University of Pennsylvania’s Wharton School. “With findings we want to see, we ask, ‘Can I believe this?’ With those we don’t, we ask, ‘Must I believe this?’

Many Academics Are Eager to Publish in Worthless Journals - The New York Times - 0 views

  • it’s increasingly clear that many academics know exactly what they’re getting into, which explains why these journals have proliferated despite wide criticism. The relationship is less predator and prey, some experts say, than a new and ugly symbiosis.
  • “When hundreds of thousands of publications appear in predatory journals, it stretches credulity to believe all the authors and universities they work for are victims,” Derek Pyne, an economics professor at Thompson Rivers University in British Columbia, wrote in a op-ed published in the Ottawa Citizen, a Canadian newspaper.
  • The journals are giving rise to a wider ecosystem of pseudo science. For the academic who wants to add credentials to a resume, for instance, publishers also hold meetings where, for a hefty fee, you can be listed as a presenter — whether you actually attend the meeting or not.
  • ...7 more annotations...
  • Many of these journals have names that closely resemble those of established publications, making them easily mistakable. There is the Journal of Economics and Finance, published by Springer, but now also the Journal of Finance and Economics. There is the Journal of Engineering Technology, put out by the American Society for Engineering Education, but now another called the GSTF Journal of Engineering Technology.
  • Predatory journals have few expenses, since they do not seriously review papers that are submitted and they publish only online. They blast emails to academics, inviting them to publish. And the journals often advertise on their websites that they are indexed by Google Scholar. Often that is correct — but Google Scholar does not vet the journals it indexes.
  • The number of such journals has exploded to more than 10,000 in recent years, with nearly as many predatory as legitimate ones. “Predatory publishing is becoming an organized industry,” wrote one group of critics in a paper in Nature
  • Participating in such dubious enterprises carries few risks. Dr. Pyne, who did a study of his colleagues publications, reports that faculty members at his school who got promoted last year had at least four papers in questionable journals. All but one academic in 10 who won a School of Business and Economics award had published papers in these journals. One had 10 such articles.
  • Academics get rewarded with promotions when they stuff their resumes with articles like these, Dr. Pyne concluded. There are few or no adverse consequences — in fact, the rewards for publishing in predatory journals were greater than for publishing in legitimate ones.
  • Some say the academic system bears much of the blame for the rise of predatory journals, demanding publications even from teachers at places without real resources for research and where they may have little time apart from teaching.At Queensborough, faculty members typically teach nine courses per year. At four-year colleges, faculty may teach four to six courses a year.
  • Recently a group of researchers who invented a fake academic: Anna O. Szust. The name in Polish means fraudster. Dr. Szust applied to legitimate and predatory journals asking to be an editor. She supplied a résumé in which her publications and degrees were total fabrications, as were the names of the publishers of the books she said she had contributed to.The legitimate journals rejected her application immediately. But 48 out of 360 questionable journals made her an editor. Four made her editor in chief. One journal sent her an email saying, “It’s our pleasure to add your name as our editor in chief for the journal with no responsibilities.”

Seven Lessons In Economic Leadership From Ancient Egypt - 0 views

  • Although there are plenty of grounds for rage against the big banks, the challenge is to sort out which are the activities that grow the real economy of goods and services, and which are the activities that are essentially a zero-sum game of socially useless gambling?
  • The situation today is that the zero-sum games of the financial sector aren’t just a tiny sideshow. They have grown exponentially and have become almost the main game of the financial sector.
  • When finance becomes the end, not the means, then the result is what analyst Gautam Mukunda calls “excessive financialization” of the economy, as his excellent article by “The Price of Wall Street Power” in the June 2014 issue of Harvard Business Review makes clear.
  • ...15 more annotations...
  • Quite apart from the “unbalanced power” of the financial sector, and the tendency of a super-sized financial sector to cause increasingly bad global financial crashes, excessive financialization leads to resources being misallocated. “In many of the financial sector’s segments that have grown fastest since deregulation—like investment banks—the transactions are primarily zero-sum.”
  • However in times of rapid technological transformation like today, the role of the economic priesthood in protecting its own interests can become a massively destabilizing.
  • Thus we know from the history of the last couple of hundred years that in times of rapid technological transformation, the financial sector tends to become disconnected from the real economy
  • This has occurred a number of times in the last few hundred years, including the Canal Mania (England—1790s), the Rail Mania (England—1840s), the Gilded Age (US: 1880s—early 1900s) the Roaring Twenties (US—1920s) and the Big Banks of today.
  • Getting to safety is not made any easier by the fact the modern economic priesthood—the managers of large firms and the banks—has, like their ancient Egyptian forbears, found ways to participate in the casino economy and benefit from “making money out of money”, even as the economy as a whole suffers.  As Upton Sinclair wrote, “It is difficult to get a man to understand something, when his salary depends upon his not understanding it.
  • Just as the ancient Egyptian economic priesthood clung to power as the economy stagnated, so today the economic priesthood shows no signs of relinquishing their gains or their power. The appetite and expectation of extraordinary returns is still there.
  • “Corporate chieftains rationally choose financial engineering—debt-financed share buybacks, for example—over capital investment in property, plants and equipment. Financial markets reward shareholder activism. Institutional investors extend their risk parameters to beat their benchmarks… But real economic growth—averaging just a bit above 2 percent for the fifth year in a row—remains sorely lacking.”
  • As a result, the economy remains in the “Great Stagnation”(Tyler Cowen), also known as “the Secular Stagnation (Larry Summers). It is running on continuing life support from the Federal Reserve. Large enterprises still appear to be profitable. The appearance, though not the reality, of economic well-being has been sufficient to make the stock market soa
  • Just as no change was possible in ancient Egyptian society so long as the economic priesthood colluded to preserve the status quo, so the excesses and prevarications of the Financial Sector will continue so long as the regulators remain its cheerleaders.
  • Just listen to the chair of the Securities and Exchange Commission (SEC), Mary Jo White at Stanford University Rock Center for Corporate Governance speaking to directors. In her speech, she makes no secret of her view that the overall corporate arrangements are sound. The job of the SEC, as outlined in the speech, is to find the odd individual who might be doing something wrong. The idea that the large-scale activities of the major banks might be socially corrosive is not even alluded.
  • Thus in times of transformational technology, there is a huge expansion of investment, driven by the financial sector. Wealthy investors begin to expect outsized returns and so there is over-investment. The resulting bubbles in due course burst
  • Just as in ancient Egypt, no progress was possible so long as the myths and rituals of the economic priesthood and their offerings to the gods were widely accepted as real indicators of what was going on, so today no progress is possible so long as the myths and rituals of the modern economic priesthood still has a pervasive hold of people’s minds
  • In the modern economy, the myths and rituals of the economic priesthood are built on the notion that the purpose of a firm is to maximize shareholder value and the notion that if the share price is increasing, things are going well. These ideas are the intellectual underpinnings of the zero-sum activities of the financial sector for “making money out of money”, by whatever means possible
  • Like the myths and rituals of the priests of ancient Egypt, shareholder value theory is espoused with religious overtones. Shareholder value, which even Jack Welch has called “the dumbest idea in the world,” remains pervasive in business, even though it is responsible for massive offshoring of manufacturing, thereby destroying major segments of the US economy, undermining US capacity to compete in international markets and killing the economic recovery.
  • If instead society decides that the financial sector should concentrate on its socially important function of financing the real economy and providing financial security for an ever wider circle of citizens and enterprises, we could enjoy an era of growth and lasting prosperity.

How Einstein Challenged Newtonian Physics - 0 views

  • Any discussion of Einstein should begin with what is probably his single greatest contribution to physics—the theory of relativity.
  • Between the late 1600s and the beginning of the 20th century, the field of physics was dominated by the ideas of Isaac Newton. The Newtonian laws of motion and gravitation had, up to that point in time, been the most successful scientific theory in all of history.
  • Newton’s ideas were, of course, challenged from time to time during those two centuries, but these ideas always seemed to hold up
  • ...9 more annotations...
  • There were many new phenomena that were discovered and that came to be understood in the centuries that followed Newton’s era. Take electricity and magnetism, for example. Until the 19th century, we didn’t really know what electricity or magnetism were, or how they worked. Isaac Newton certainly didn’t have a clue.
  • To many physicists around the turn of the 20th century, the state of physics seemed very settled. The Newtonian worldview had been very successful, and for a very long time.
  • In 1905, however, a revolution in physics did come. And perhaps even more surprising than the revolution itself was where that revolution came from. In 1905, Albert Einstein was not working as a professor at some prestigious university. He was not famous, or even well-known among other physicists.
  • Things didn’t stay this way for long, however. In 1905, Einstein wrote not one or two, but four absolutely groundbreaking papers. Any one of these four papers would have made him a star within the field of physics, and would have certainly secured him a position of prominence in the history of science.
  • It seems that having so many breakthroughs of this magnitude in such a short period of time had never happened before, and has never happened since. In the first of Einstein’s 1905 papers, he proposed that light doesn’t only behave like a wave, but that it is also made up of individual pieces or particles.
  • But Einstein’s paper provided concrete empirical evidence that atoms were, in fact, real and tangible objects. He was even able to use these arguments to make a pretty good estimate for the size and mass of atoms and molecules. It was a huge step forward.
  • The equations that physicists use to describe the propagation of light waves—what are known as Maxwell’s equations—predict that light should move through space at a speed of about 670 million miles per hour. And more interestingly, these equations don’t make any reference to any medium that the light waves propagate through.
  • Although no experiment had ever detected this aether, they argued that it must fill virtually all of space. After all, they argued, the light from a distant star could only reach us if there was a continuous path filled with aether, extending all the way from the star to us.
  • ventually, though, physicists discovered that there was no aether. It would be Einstein who would come up with an equation to explain this conundrum.

4 Everyday Items Einstein Helped Create - 0 views

  • Albert Einstein is justly famous for devising his theory of relativity, which revolutionized our understanding of space, time, gravity, and the universe. Relativity also showed us that matter and energy are just two different forms of the same thing—a fact that Einstein expressed as E=mc2, the most widely recognized equation in history.
  • Credit for inventing paper towels goes to the Scott Paper Company of Pennsylvania, which introduced the disposable product in 1907 as a more hygienic alternative to cloth towels. But in the very first physics article that Einstein ever published, he did analyze wicking: the phenomenon that allows paper towels to soak up liquids even when gravity wants to drag the fluid downward.
  • Again, Einstein didn’t invent solar cells; the first crude versions of them date back to 1839. But he did sketch out their basic principle of operation in 1905. His starting point was a simple analogy: If matter is lumpy—that is, if every substance in the universe consists of atoms and molecules—then surely light must be lumpy as well.
  • ...5 more annotations...
  • Einstein turned this insight into an equation that described the jittering mathematically. His Brownian motion paper is widely recognized as the first incontrovertible proof that atoms and molecules really exist—and it still serves as the basis for some stock market forecasts.
  • He was trying to explain an odd fact that was first noticed by English botanist Robert Brown in 1827. Brown looked through his microscope and saw that the dust grains in a droplet of water were jittering around aimlessly. This Brownian motion, as it was first dubbed, had nothing to do with the grains being alive, so what kept them moving?
  • If you’ve been to a conference or played with a cat, chances are you’ve seen a laser pointer in action. In the nearly six decades since physicists demonstrated the first laboratory prototype of a laser in 1960, the devices have come to occupy almost every niche imaginable, from barcode readers to systems for hair removal.
  • So Einstein made an inspired guess: Maybe photons like to march in step, so that the presence of a bunch of them going in the same direction will increase the probability of a high-energy atom emitting another photon in that direction. He called this process stimulated emission, and when he included it in his equations, his calculations fit the observations perfectly
  • A laser is just a gadget for harnessing this phenomenon

Gen Z Never Learned to Read Cursive - The Atlantic - 0 views

  • Who else can’t read cursive? I asked the class. The answer: about two-thirds. And who can’t write it? Even more. What did they do about signatures? They had invented them by combining vestiges of whatever cursive instruction they may have had with creative squiggles and flourishes.
  • Most of my students remembered getting no more than a year or so of somewhat desultory cursive training, which was often pushed aside by a growing emphasis on “teaching to the test.” Now in college, they represent the vanguard of a cursiveless world.

  • there are dangers in cursive’s loss. Students will miss the excitement and inspiration that I have seen them experience as they interact with the physical embodiment of thoughts and ideas voiced by a person long since silenced by death. Handwriting can make the past seem almost alive in the present.
  • All of us, not just students and scholars, will be affected by cursive’s loss. The inability to read handwriting deprives society of direct access to its own past. We will become reliant on a small group of trained translators and experts to report what history—including the documents and papers of our own families—was about.
  • The spread of literacy in the early modern West was driven by people’s desire to read God’s word for themselves, to be empowered by an experience of unmediated connection. The abandonment of cursive represents a curious reverse parallel: We are losing a connection, and thereby disempowering ourselves.

Gamblers, Scientists and the Mysterious Hot Hand - The New York Times - 0 views

  • Psychologists who study how the human mind responds to randomness call this the gambler’s fallacy — the belief that on some cosmic plane a run of bad luck creates an imbalance that must ultimately be corrected, a pressure that must be relieved
  • The opposite of that is the hot-hand fallacy — the belief that winning streaks, whether in basketball or coin tossing, have a tendency to continue
  • Both misconceptions are reflections of the brain’s wired-in rejection of the power that randomness holds over our lives. Look deep enough, we instinctively believe, and we may uncover a hidden order.
  • ...11 more annotations...
  • A working paper published this summer has caused a stir by proposing that a classic body of research disproving the existence of the hot hand in basketball is flawed by a subtle misperception about randomness. If the analysis is correct, the possibility remains that the hot hand is real.
  • We mortals can benefit, at least in theory, from islands of predictability — a barely perceptible tilt of a roulette table that makes the ball slightly more likely to land on one side of the wheel than the other
  • The same is true for the random walk of the stock market. Becoming aware of information before it has propagated worldwide can give a speculator a tiny, temporary edge. Some traders pay a premium to locate their computer servers as close as possible to Lower Manhattan, gaining advantages measured in microseconds.
  • Taken to extremes, seeing connections that don’t exist can be a symptom of a psychiatric condition called apophenia. In less pathological forms, the brain’s hunger for pattern gives rise to superstitions (astrology, numerology) and is a driving factor in what has been called a replication crisis in science
  • I know it sounds crazy but when you average the scores together the answer is not 50-50, as most people would expect, but about 40-60 in favor of tails.
  • There is not, as Guildenstern might imagine, a tear in the fabric of space-time. It remains as true as ever that each flip is independent, with even odds that the coin will land one way or the other. But by concentrating on only some of the data — the flips that follow heads — a gambler falls prey to a selection bias.
  • basketball is no streakier than a coin toss. For a 50 percent shooter, for example, the odds of making a basket are supposed to be no better after a hit — still 50-50. But in a purely random situation, according to the new analysis, a hit would be expected to be followed by another hit less than half the time. Finding 50 percent would actually be evidence in favor of the hot hand
  • Dr. Gilovich is withholding judgment. “The larger the sample of data for a given player, the less of an issue this is,” he wrote in an email. “Because our samples were fairly large, I don’t believe this changes the original conclusions about the hot hand. ”
  • Take a fair coin — one as likely to land on heads as tails — and flip it four times. How often was heads followed by another head?
  • For all their care to be objective, scientists are as prone as anyone to valuing data that support their hypothesis over those that contradict it. Sometimes this results in experiments that succeed only under very refined conditions, in certain labs with special reagents and performed by a scientist with a hot hand.
  • We’re all in the same boat. We evolved with this uncanny ability to find patterns. The difficulty lies in separating what really exists from what is only in our minds.
