Organ Transplant Trade Internet Bioethics

shared by Weiye Loh on 23 Jun 11 - No Cached
  • All of this Internet activity is but the tip of the iceberg of a new and growing global human-tissue economy. Indeed, the World Health Organization (WHO) has estimated that about 10% of organ transplants around the world stem from purely commercial transactions.
  • Trade in organs follows a clear, geographically linked pattern: people from rich countries buy the organs, and people in poor countries sell them. In my research on organ trafficking, I have entered some of these shadow markets, where body parts from the poor, war victims, and prisoners are commodities, bought or stolen for transplant into affluent ill people.
  • Organ trafficking depends on several factors. One is people in distress. They are economically or socially disadvantaged, or live in war-torn societies with prevalent crime and a thriving black market. On the demand side are people who are in danger of dying unless they receive an organ transplant. Additionally, there are organ brokers who arrange the deals between sellers and buyers.

  • Trade in humans and their bodies is not a new phenomenon, but today’s businesses are historically unique, because they require advanced biomedicine, as well as ideas and values that enhance the trade in organs. Western medicine starts from the view that human illness and death are failures to be combated. It is within this conceptual climate – the dream of the regenerative body – that transplantation technology develops and demand for biological replacement parts grows.
  • In an era of transplants on demand, there is no way around this dilemma. The biological imperatives that guide the priority system of transplant waiting lists are easily transformed into economic values. As always where demand exceeds supply, people may not accept waiting their turn – and other countries and other peoples’ bodies give them the alternative they seek.

    The Web site 88DB.com Philippines is an active online portal that allows service providers and consumers to find and interact with each other. Naoval, an Indonesian man with "AB blood type, no drugs and no alcohol," wants to sell his kidney. Another man says, "I am a Filipino. I am willing to sell my kidney for my wife. She has breast cancer and I can't afford her medications." Then there is Enrique, who is "willing to donate my kidney for an exchange. 21 years old and healthy." Other offers of this type could, just a few years ago, be found at www.liver4you.org, which promised kidneys for $80,000-$110,000. The costs of the operation, including the fees of the surgeons - licensed in the United States, Great Britain, or the Philippines - would be included in the price.

  • . Is it morally permissible to submit to total instrumentalization living beings that, though they do not have a central nervous system, are capable of basic learning and communication? Should their swift response to stress leave us coldly indifferent, while animal suffering provokes intense feelings of pity and compassion?
  • When it comes to a plant, it turns out to be not only a what but also a who — an agent in its milieu, with its own intrinsic value or version of the good. Inquiring into justifications for consuming vegetal beings thus reconceived, we reach one of the final frontiers of dietary ethics.

  • the subjectivity of plants is not centered in a single organ or function but is dispersed throughout their bodies, from the roots to the leaves and shoots. Nevertheless, this dispersion of vitality holds out a promise of its own: the plasticity of plants and their wondrous capacity for regeneration, their growth by increments, quantitative additions or reiterations of already existing parts does little to change the form of living beings that are neither parts nor wholes because they are not hierarchically structured organisms. The “renewable” aspects of perennial plants may be accepted by humans as a gift of vegetal being and integrated into their diets.
  • The desire to eat ethically is, perhaps, akin to this royal sensitivity, as some would argue that it is a luxury of those who do have enough food to select, in a conscious manner, their dietary patterns.

    a pea plant subjected to drought conditions communicated its stress to other such plants, with which it shared its soil. In other words, through the roots, it relayed to its neighbors the biochemical message about the onset of drought, prompting them to react as though they, too, were in a similar predicament. Curiously, having received the signal, plants not directly affected by this particular environmental stress factor were better able to withstand adverse conditions when they actually occurred. This means that the recipients of biochemical communication could draw on their "memories" - information stored at the cellular level - to activate appropriate defenses and adaptive responses when the need arose.

Climate Science ClimateGate

  • Sen. Jim Inhofe's (R-OK) biggest claim to fame has been his oft-repeated line that global warming is "the greatest hoax ever perpetrated on the American people."
  • In 2003, he conceded that the earth was warming, but denied it was caused by human activity and suggested that "increases in global temperatures may have a beneficial effect on how we live our lives."
  • In 2009, however, he appeared on Fox News to declare that the earth was actually cooling, claiming "everyone understands that's the case" (they don't, because it isn't).

  • nhofe's battle against climate science kicked into overdrive when a series of illegally obtained emails surfaced from the Climatic Research Unit at East Anglia University. 
  • When the dubious reports surfaced about flawed science, manipulated data, and unsubstantiated studies, Inhofe was ecstatic.  In March, he viciously attacked former Vice President Al Gore for defending the science behind climate change
  • Unfortunately for Senator Inhofe, none of those things are true.  One by one, the pillars of evidence supporting the alleged "scandals" have shattered, causing the entire "Climategate" storyline to come crashing down. 
  • a panel established by the University of East Anglia to investigate the integrity of the research of the Climatic Research Unit wrote: "We saw no evidence of any deliberate scientific malpractice in any of the work of the Climatic Research Unit and had it been there we believe that it is likely that we would have detected it."
  • Responding to allegations that Dr. Michael Mann tampered with scientific evidence, Pennsylvania State University conducted a thorough investigation. It concluded: "The Investigatory Committee, after careful review of all available evidence, determined that there is no substance to the allegation against Dr. Michael E. Mann, Professor, Department of Meteorology, The Pennsylvania State University.  More specifically, the Investigatory Committee determined that Dr. Michael E. Mann did not engage in, nor did he participate in, directly or indirectly, any actions that seriously deviated from accepted practices within the academic community for proposing, conducting, or reporting research, or other scholarly activities."
  • London's Sunday Times retracted its story, echoed by dozens of outlets, that an IPCC issued an unsubstantiated report claiming 40% of the Amazon rainforest was endangered due to changing rainfall patterns.  The Times wrote: "In fact, the IPCC's Amazon statement is supported by peer-reviewed scientific evidence. In the case of the WWF report, the figure had, in error, not been referenced, but was based on research by the respected Amazon Environmental Research Institute (IPAM) which did relate to the impact of climate change."
  • The Times also admitted it misrepresented the views of Dr. Simon Lewis, a Royal Society research fellow at the University of Leeds, implying he agreed with the article's false premise and believed the IPCC should not utilize reports issued by outside organizations.  In its retraction, the Times was forced to admit: "Dr Lewis does not dispute the scientific basis for both the IPCC and the WWF reports," and, "We accept that Dr Lewis holds no such view... A version of our article that had been checked with Dr Lewis underwent significant late editing and so did not give a fair or accurate account of his views on these points. We apologise for this."

Scam Scams Scammer Nigeria Nigerian 419scam Vigilantism Vigilante 419eater

shared by Jianwei Tan on 19 Aug 09 - Cached
  • Jianwei Tan on 19 Aug 09
     
    Summary: Some people may have heard of the Nigerian 419 scams that were very infamous quite a few years back. These scammers who supposedly operated out of Nigeria created elaborate stories and solicited for help through e-mails. Although the initial intention of the e-mail is to ask for help, subsequent correspondences usually result in the scammer requesting for monetary aid through wire transfer. This person, Mike, has taken it upon himself to declare war on these scammers, baiting them to believe that he would send money to them but in actual fact plays pranks on them. The pranks played range from telling silly stories and wasting the scammer's time to persuading the scammer to get tattooed in order to get the money. Question: Scams are, without a doubt, unethical and probably criminal activities. However, is the act of scamming a would-be scammer an ethical thing to do? Problem: Let's imagine a situation where the scammer and the scambaiter (the person scamming the scammer) are from the same country or even the same state, thus both parties would be subject to the same laws. If the scammer were to try and launch a scam and instead was scambaited into severe consequences (I think getting tattoed is quite severe), should the scambaiter be prosecuted by the legal system?

    To summarize the article, it basically talks about a hacker who used his Twitter account to send out messages that were in turn used to direct the infected PCs to malicious websites. Ethical Question: I think it is actually quite important to look at the intention behind using technology in this way. In this case, the hacker took advantage of his Twitter account to engage in criminal activities. But what if this for of hacking was used to perhaps take down an online criminal ring? Would it still be considered 'right' or 'ethical' to hack into other people's computers in that case? Ethical Problem: I think the main problem would be accountability. To what extent should Twitter be held responsible?

skepticism Ethics Polarisation

shared by Weiye Loh on 13 Sep 10 - No Cached
  • My recent post “The War Over ‘Nice’” (describing the blogosphere’s reaction to Phil Plait’s “Don’t Be a Dick” speech) has topped out at more than 200 comments.
  • Many readers appear to object (some strenuously) to the very ideas of discussing best practices, seeking evidence of efficacy for skeptical outreach, matching strategies to goals, or encouraging some methods over others. Some seem to express anger that a discussion of best practices would be attempted at all. 
  • No Right or Wrong Way? The milder forms of these objections run along these lines: “Everyone should do their own thing.” “Skepticism needs all kinds of approaches.” “There’s no right or wrong way to do skepticism.” “Why are we wasting time on these abstract meta-conversations?”
  • ...12 more annotations...
  • More critical, in my opinion, is the implication that skeptical research and communication happens in an ethical vacuum. That just isn’t true. Indeed, it is dangerous for a field which promotes and attacks medical treatments, accuses people of crimes, opines about law enforcement practices, offers consumer advice, and undertakes educational projects to pretend that it is free from ethical implications — or obligations.
  • there is no monolithic “one true way to do skepticism.” No, the skeptical world does not break down to nice skeptics who get everything right, and mean skeptics who get everything wrong. (I’m reminded of a quote: “If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being.”) No one has all the answers. Certainly I don’t, and neither does Phil Plait. Nor has anyone actually proposed a uniform, lockstep approach to skepticism. (No one has any ability to enforce such a thing, in any event.)
  • However, none of that implies that all approaches to skepticism are equally valid, useful, or good. As in other fields, various skeptical practices do more or less good, cause greater or lesser harm, or generate various combinations of both at the same time. For that reason, skeptics should strive to find ways to talk seriously about the practices and the ethics of our field. Skepticism has blossomed into something that touches a lot of lives — and yet it is an emerging field, only starting to come into its potential. We need to be able to talk about that potential, and about the pitfalls too.
  • All of the fields from which skepticism borrows (such as medicine, education, psychology, journalism, history, and even arts like stage magic and graphic design) have their own standards of professional ethics. In some cases those ethics are well-explored professional fields in their own right (consider medical ethics, a field with its own academic journals and doctoral programs). In other cases those ethical guidelines are contested, informal, vague, or honored more in the breach. But in every case, there are serious conversations about the ethical implications of professional practice, because those practices impact people’s lives. Why would skepticism be any different?
  • , Skeptrack speaker Barbara Drescher (a cognitive pyschologist who teaches research methodology) described the complexity of research ethics in her own field. Imagine, she said, that a psychologist were to ask research subjects a question like, “Do your parents like the color red?” Asking this may seem trivial and harmless, but it is nonetheless an ethical trade-off with associated risks (however small) that psychological researchers are ethically obliged to confront. What harm might that question cause if a research subject suffers from erythrophobia, or has a sick parent — or saw their parents stabbed to death?
  • When skeptics undertake scientific, historical, or journalistic research, we should (I argue) consider ourselves bound by some sort of research ethics. For now, we’ll ignore the deeper, detailed question of what exactly that looks like in practical terms (when can skeptics go undercover or lie to get information? how much research does due diligence require? and so on). I’d ask only that we agree on the principle that skeptical research is not an ethical free-for-all.
  • when skeptics communicate with the public, we take on further ethical responsibilities — as do doctors, journalists, and teachers. We all accept that doctors are obliged to follow some sort of ethical code, not only of due diligence and standard of care, but also in their confidentiality, manner, and the factual information they disclose to patients. A sentence that communicates a diagnosis, prescription, or piece of medical advice (“you have cancer” or “undertake this treatment”) is not a contextless statement, but a weighty, risky, ethically serious undertaking that affects people’s lives. It matters what doctors say, and it matters how they say it.
  • Grassroots Ethics It happens that skepticism is my professional field. It’s natural that I should feel bound by the central concerns of that field. How can we gain reliable knowledge about weird things? How can we communicate that knowledge effectively? And, how can we pursue that practice ethically?
  • At the same time, most active skeptics are not professionals. To what extent should grassroots skeptics feel obligated to consider the ethics of skeptical activism? Consider my own status as a medical amateur. I almost need super-caps-lock to explain how much I am not a doctor. My medical training began and ended with a couple First Aid courses (and those way back in the day). But during those short courses, the instructors drummed into us the ethical considerations of our minimal training. When are we obligated to perform first aid? When are we ethically barred from giving aid? What if the injured party is unconscious or delirious? What if we accidentally kill or injure someone in our effort to give aid? Should we risk exposure to blood-borne illnesses? And so on. In a medical context, ethics are determined less by professional status, and more by the harm we can cause or prevent by our actions.
  • police officers are barred from perjury, and journalists from libel — and so are the lay public. We expect schoolteachers not to discuss age-inappropriate topics with our young children, or to persuade our children to adopt their religion; when we babysit for a neighbor, we consider ourselves bound by similar rules. I would argue that grassroots skeptics take on an ethical burden as soon as they speak out on medical matters, legal matters, or other matters of fact, whether from platforms as large as network television, or as small as a dinner party. The size of that burden must depend somewhat on the scale of the risks: the number of people reached, the certainty expressed, the topics tackled.
  • tu-quoque argument.
  • How much time are skeptics going to waste, arguing in a circular firing squad about each other’s free speech? Like it or not, there will always be confrontational people. You aren’t going to get a group of people as varied as skeptics are, and make them all agree to “be nice”. It’s a pipe dream, and a waste of time.

Social Media Social Network Sites Twitter Facebook Morality

shared by Weiye Loh on 07 Oct 10 - Cached
  • 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.

  • When plant biologists speak of their subjects, they use active verbs and vivid images. Plants “forage” for resources like light and soil nutrients and “anticipate” rough spots and opportunities.
  • Plants can’t run away from a threat but they can stand their ground. “They are very good at avoiding getting eaten,”
  • At the smallest nip to its leaves, specialized cells on the plant’s surface release chemicals to irritate the predator or sticky goo to entrap it. Genes in the plant’s DNA are activated to wage systemwide chemical warfare, the plant’s version of an immune response.
  • in less than 20 minutes from the moment the caterpillar had begun feeding on its leaves, the plant had plucked carbon from the air and forged defensive compounds from scratch.
  • Just because we humans can’t hear them doesn’t mean plants don’t howl. Some of the compounds that plants generate in response to insect mastication — their feedback, you might say — are volatile chemicals that serve as cries for help. Such airborne alarm calls have been shown to attract both large predatory insects like dragon flies, which delight in caterpillar meat, and tiny parasitic insects, which can infect a caterpillar and destroy it from within.
  • certain plants can sense when insect eggs have been deposited on their leaves and will act immediately to rid themselves of the incubating menace. They may sprout carpets of tumorlike neoplasms to knock the eggs off, or secrete ovicides to kill them
  • when a female cabbage butterfly lays her eggs on a brussels sprout plant and attaches her treasures to the leaves with tiny dabs of glue, the vigilant vegetable detects the presence of a simple additive in the glue, benzyl cyanide. Cued by the additive, the plant swiftly alters the chemistry of its leaf surface to beckon female parasitic wasps. Spying the anchored bounty, the female wasps in turn inject their eggs inside, the gestating wasps feed on the gestating butterflies, and the plant’s problem is solved.
  • seedlings of the dodder plant, a parasitic weed related to morning glory, can detect volatile chemicals released by potential host plants like the tomato. The young dodder then grows inexorably toward the host, until it can encircle the victim’s stem and begin sucking the life phloem right out of it. The parasite can even distinguish between the scents of healthier and weaker tomato plants and then head for the hale one.
  • It’s a small daily tragedy that we animals must kill to stay alive. Plants are the ethical autotrophs here, the ones that wrest their meals from the sun. Don’t expect them to boast: they’re too busy fighting to survive.

  • By Carlin Romano Standing up for science excites some intellectuals the way beautiful actresses arouse Warren Beatty, or career liberals boil the blood of Glenn Beck and Rush Limbaugh. It's visceral.
  • A brave champion of beleaguered science in the modern age of pseudoscience, this Ayn Rand protagonist sarcastically derides the benighted irrationalists and glows with a self-anointed superiority. Who wouldn't want to feel that sense of power and rightness?
  • You hear the voice regularly—along with far more sensible stuff—in the latest of a now common genre of science patriotism, Nonsense on Stilts: How to Tell Science From Bunk (University of Chicago Press), by Massimo Pigliucci, a philosophy professor at the City University of New York.
  • ...24 more annotations...
  • it mixes eminent common sense and frequent good reporting with a cocksure hubris utterly inappropriate to the practice it apotheosizes.
  • According to Pigliucci, both Freudian psychoanalysis and Marxist theory of history "are too broad, too flexible with regard to observations, to actually tell us anything interesting." (That's right—not one "interesting" thing.) The idea of intelligent design in biology "has made no progress since its last serious articulation by natural theologian William Paley in 1802," and the empirical evidence for evolution is like that for "an open-and-shut murder case."
  • Pigliucci offers more hero sandwiches spiced with derision and certainty. Media coverage of science is "characterized by allegedly serious journalists who behave like comedians." Commenting on the highly publicized Dover, Pa., court case in which U.S. District Judge John E. Jones III ruled that intelligent-design theory is not science, Pigliucci labels the need for that judgment a "bizarre" consequence of the local school board's "inane" resolution. Noting the complaint of intelligent-design advocate William Buckingham that an approved science textbook didn't give creationism a fair shake, Pigliucci writes, "This is like complaining that a textbook in astronomy is too focused on the Copernican theory of the structure of the solar system and unfairly neglects the possibility that the Flying Spaghetti Monster is really pulling each planet's strings, unseen by the deluded scientists."
  • Or is it possible that the alternate view unfairly neglected could be more like that of Harvard scientist Owen Gingerich, who contends in God's Universe (Harvard University Press, 2006) that it is partly statistical arguments—the extraordinary unlikelihood eons ago of the physical conditions necessary for self-conscious life—that support his belief in a universe "congenially designed for the existence of intelligent, self-reflective life"?
  • Even if we agree that capital "I" and "D" intelligent-design of the scriptural sort—what Gingerich himself calls "primitive scriptural literalism"—is not scientifically credible, does that make Gingerich's assertion, "I believe in intelligent design, lowercase i and lowercase d," equivalent to Flying-Spaghetti-Monsterism? Tone matters. And sarcasm is not science.
  • The problem with polemicists like Pigliucci is that a chasm has opened up between two groups that might loosely be distinguished as "philosophers of science" and "science warriors."
  • Philosophers of science, often operating under the aegis of Thomas Kuhn, recognize that science is a diverse, social enterprise that has changed over time, developed different methodologies in different subsciences, and often advanced by taking putative pseudoscience seriously, as in debunking cold fusion
  • The science warriors, by contrast, often write as if our science of the moment is isomorphic with knowledge of an objective world-in-itself—Kant be damned!—and any form of inquiry that doesn't fit the writer's criteria of proper science must be banished as "bunk." Pigliucci, typically, hasn't much sympathy for radical philosophies of science. He calls the work of Paul Feyerabend "lunacy," deems Bruno Latour "a fool," and observes that "the great pronouncements of feminist science have fallen as flat as the similarly empty utterances of supporters of intelligent design."
  • It doesn't have to be this way. The noble enterprise of submitting nonscientific knowledge claims to critical scrutiny—an activity continuous with both philosophy and science—took off in an admirable way in the late 20th century when Paul Kurtz, of the University at Buffalo, established the Committee for the Scientific Investigation of Claims of the Paranormal (Csicop) in May 1976. Csicop soon after launched the marvelous journal Skeptical Inquirer
  • Although Pigliucci himself publishes in Skeptical Inquirer, his contributions there exhibit his signature smugness. For an antidote to Pigliucci's overweening scientism 'tude, it's refreshing to consult Kurtz's curtain-raising essay, "Science and the Public," in Science Under Siege (Prometheus Books, 2009, edited by Frazier)
  • Kurtz's commandment might be stated, "Don't mock or ridicule—investigate and explain." He writes: "We attempted to make it clear that we were interested in fair and impartial inquiry, that we were not dogmatic or closed-minded, and that skepticism did not imply a priori rejection of any reasonable claim. Indeed, I insisted that our skepticism was not totalistic or nihilistic about paranormal claims."
  • Kurtz combines the ethos of both critical investigator and philosopher of science. Describing modern science as a practice in which "hypotheses and theories are based upon rigorous methods of empirical investigation, experimental confirmation, and replication," he notes: "One must be prepared to overthrow an entire theoretical framework—and this has happened often in the history of science ... skeptical doubt is an integral part of the method of science, and scientists should be prepared to question received scientific doctrines and reject them in the light of new evidence."
  • Pigliucci, alas, allows his animus against the nonscientific to pull him away from sensitive distinctions among various sciences to sloppy arguments one didn't see in such earlier works of science patriotism as Carl Sagan's The Demon-Haunted World: Science as a Candle in the Dark (Random House, 1995). Indeed, he probably sets a world record for misuse of the word "fallacy."
  • To his credit, Pigliucci at times acknowledges the nondogmatic spine of science. He concedes that "science is characterized by a fuzzy borderline with other types of inquiry that may or may not one day become sciences." Science, he admits, "actually refers to a rather heterogeneous family of activities, not to a single and universal method." He rightly warns that some pseudoscience—for example, denial of HIV-AIDS causation—is dangerous and terrible.
  • But at other points, Pigliucci ferociously attacks opponents like the most unreflective science fanatic
  • He dismisses Feyerabend's view that "science is a religion" as simply "preposterous," even though he elsewhere admits that "methodological naturalism"—the commitment of all scientists to reject "supernatural" explanations—is itself not an empirically verifiable principle or fact, but rather an almost Kantian precondition of scientific knowledge. An article of faith, some cold-eyed Feyerabend fans might say.
  • He writes, "ID is not a scientific theory at all because there is no empirical observation that can possibly contradict it. Anything we observe in nature could, in principle, be attributed to an unspecified intelligent designer who works in mysterious ways." But earlier in the book, he correctly argues against Karl Popper that susceptibility to falsification cannot be the sole criterion of science, because science also confirms. It is, in principle, possible that an empirical observation could confirm intelligent design—i.e., that magic moment when the ultimate UFO lands with representatives of the intergalactic society that planted early life here, and we accept their evidence that they did it.
  • "As long as we do not venture to make hypotheses about who the designer is and why and how she operates," he writes, "there are no empirical constraints on the 'theory' at all. Anything goes, and therefore nothing holds, because a theory that 'explains' everything really explains nothing."
  • Here, Pigliucci again mixes up what's likely or provable with what's logically possible or rational. The creation stories of traditional religions and scriptures do, in effect, offer hypotheses, or claims, about who the designer is—e.g., see the Bible.
  • Far from explaining nothing because it explains everything, such an explanation explains a lot by explaining everything. It just doesn't explain it convincingly to a scientist with other evidentiary standards.
  • A sensible person can side with scientists on what's true, but not with Pigliucci on what's rational and possible. Pigliucci occasionally recognizes that. Late in his book, he concedes that "nonscientific claims may be true and still not qualify as science." But if that's so, and we care about truth, why exalt science to the degree he does? If there's really a heaven, and science can't (yet?) detect it, so much the worse for science.
  • Pigliucci quotes a line from Aristotle: "It is the mark of an educated mind to be able to entertain a thought without accepting it." Science warriors such as Pigliucci, or Michael Ruse in his recent clash with other philosophers in these pages, should reflect on a related modern sense of "entertain." One does not entertain a guest by mocking, deriding, and abusing the guest. Similarly, one does not entertain a thought or approach to knowledge by ridiculing it.
  • Long live Skeptical Inquirer! But can we deep-six the egomania and unearned arrogance of the science patriots? As Descartes, that immortal hero of scientists and skeptics everywhere, pointed out, true skepticism, like true charity, begins at home.

Medicine Placebo Research

shared by Weiye Loh on 24 Dec 10 - No Cached
  • In modern medicine, placebos are associated with another form of deception — a kind that has long been thought essential for conducting randomized clinical trials of new drugs, the statistical rock upon which the global pharmaceutical industry was built. One group of volunteers in an RCT gets the novel medication; another group (the “control” group) gets pills or capsules that look identical to the allegedly active drug, but contain only an inert substance like milk sugar. These faux drugs are called placebos.
  • Inevitably, the health of some people in both groups improves, while the health of others grows worse. Symptoms of illness fluctuate for all sorts of reasons, including regression to the mean.
  • Since the goal of an RCT, from Big Pharma’s perspective, is to demonstrate the effectiveness of a new drug, the return to robust health of a volunteer in the control group is considered a statistical distraction. If too many people in the trial get better after downing sugar pills, the real drug will look worse by comparison — sometimes fatally so for the purpose of earning approval from the Food and Drug Adminstration.

  • For a complex and somewhat mysterious set of reasons, it is becoming increasingly difficult for experimental drugs to prove their superiority to sugar pills in RCTs
  • in recent years, however, has it become obvious that the abatement of symptoms in control-group volunteers — the so-called placebo effect — is worthy of study outside the context of drug trials, and is in fact profoundly good news to anyone but investors in Pfizer, Roche, and GlaxoSmithKline.
  • The emerging field of placebo research has revealed that the body’s repertoire of resilience contains a powerful self-healing network that can help reduce pain and inflammation, lower the production of stress chemicals like cortisol, and even tame high blood pressure and the tremors of Parkinson’s disease.
  • more and more studies each year — by researchers like Fabrizio Benedetti at the University of Turin, author of a superb new book called The Patient’s Brain, and neuroscientist Tor Wager at the University of Colorado — demonstrate that the placebo effect might be potentially useful in treating a wide range of ills. Then why aren’t doctors supposed to use it?
  • The medical establishment’s ethical problem with placebo treatment boils down to the notion that for fake drugs to be effective, doctors must lie to their patients. It has been widely assumed that if a patient discovers that he or she is taking a placebo, the mind/body password will no longer unlock the network, and the magic pills will cease to do their job.
  • For “Placebos Without Deception,” the researchers tracked the health of 80 volunteers with irritable bowel syndrome for three weeks as half of them took placebos and the other half didn’t.
  • In a previous study published in the British Medical Journal in 2008, Kaptchuk and Kirsch demonstrated that placebo treatment can be highly effective for alleviating the symptoms of IBS. This time, however, instead of the trial being “blinded,” it was “open.” That is, the volunteers in the placebo group knew that they were getting only inert pills — which they were instructed to take religiously, twice a day. They were also informed that, just as Ivan Pavlov trained his dogs to drool at the sound of a bell, the body could be trained to activate its own built-in healing network by the act of swallowing a pill.
  • In other words, in addition to the bogus medication, the volunteers were given a true story — the story of the placebo effect. They also received the care and attention of clinicians, which have been found in many other studies to be crucial for eliciting placebo effects. The combination of the story and a supportive clinical environment were enough to prevail over the knowledge that there was really nothing in the pills. People in the placebo arm of the trial got better — clinically, measurably, significantly better — on standard scales of symptom severity and overall quality of life. In fact, the volunteers in the placebo group experienced improvement comparable to patients taking a drug called alosetron, the standard of care for IBS. Meet the ethical placebo: a powerfully effective faux medication that meets all the standards of informed consent.
  • The study is hardly the last word on the subject, but more like one of the first. Its modest sample size and brief duration leave plenty of room for followup research. (What if “ethical” placebos wear off more quickly than deceptive ones? Does the fact that most of the volunteers in this study were women have any bearing on the outcome? Were any of the volunteers skeptical that the placebo effect is real, and did that affect their response to treatment?) Before some eager editor out there composes a tweet-baiting headline suggesting that placebos are about to drive Big Pharma out of business, he or she should appreciate the fact that the advent of AMA-approved placebo treatments would open numerous cans of fascinatingly tangled worms. For example, since the precise nature of placebo effects is shaped largely by patients’ expectations, would the advertised potency and side effects of theoretical products like Placebex and Therastim be subject to change by Internet rumors, requiring perpetual updating?
  • It’s common to use the word “placebo” as a synonym for “scam.” Economists talk about placebo solutions to our economic catastrophe (tax cuts for the rich, anyone?). Online skeptics mock the billion-dollar herbal-medicine industry by calling it Big Placebo. The fact that our brains and bodies respond vigorously to placebos given in warm and supportive clinical environments, however, turns out to be very real.
  • We’re also discovering that the power of narrative is embedded deeply in our physiology.
  • in the real world of doctoring, many physicians prescribe medications at dosages too low to have an effect on their own, hoping to tap into the body’s own healing resources — though this is mostly acknowledged only in whispers, as a kind of trade secret.
