Ethics Neuropsychology

shared by Weiye Loh on 04 Jan 11 - No Cached
  • Joshua Greene from Harvard, known for his research on "neuroethics," the neurological underpinnings of ethical decision making in humans. The title of Greene's talk was "Beyond point-and-shoot morality: why cognitive neuroscience matters for ethics."
  • What Greene is interested in is to find out to what factors moral judgment is sensitive to, and whether it is sensitive to the relevant factors. He presented his dual process theory of morality. In this respect, he proposed an analogy with a camera. Cameras have automatic (point and shoot) settings as well as manual controls. The first mode is good enough for most purposes, the second allows the user to fine tune the settings more carefully. The two modes allow for a nice combination of efficiency and flexibility.
  • The idea is that the human brain also has two modes, a set of efficient automatic responses and a manual mode that makes us more flexible in response to non standard situations. The non moral example is our response to potential threats. Here the amygdala is very fast and efficient at focusing on potential threats (e.g., the outline of eyes in the dark), even when there actually is no threat (it's a controlled experiment in a lab, no lurking predator around).
  • ...12 more annotations...
  • Delayed gratification illustrates the interaction between the two modes. The brain is attracted by immediate rewards, no matter what kind. However, when larger rewards are eventually going to become available, other parts of the brain come into play to override (sometimes) the immediate urge.
  • Greene's research shows that our automatic setting is "Kantian," meaning that our intuitive responses are deontological, rule driven. The manual setting, on the other hand, tends to be more utilitarian / consequentialist. Accordingly, the first mode involves emotional areas of the brain, the second one involves more cognitive areas.
  • The evidence comes from the (in)famous trolley dilemma and it's many variations.
  • when people refuse to intervene in the footbridge (as opposed to the lever) version of the dilemma, they do so because of a strong emotional response, which contradicts the otherwise utilitarian calculus they make when considering the lever version.
  • psychopaths turn out to be more utilitarian than normal subjects - presumably not because consequentialism is inherently pathological, but because their emotional responses are stunted. Mood also affects the results, with people exposed to comedy (to enhance mood), for instance, more likely to say that it is okay to push the guy off the footbridge.
  • In a more recent experiment, subjects were asked to say which action carried the better consequences, which made them feel worse, and which was overall morally acceptable. The idea was to separate the cognitive, emotional and integrative aspects of moral decision making. Predictably, activity in the amygdala correlated with deontological judgment, activity in more cognitive areas was associated with utilitarianism, and different brain regions became involved in integrating the two.
  • Another recent experiment used visual vs. verbal descriptions of moral dilemmas. Turns out that more visual people tend to behave emotionally / deontologically, while more verbal people are more utilitarian.
  • studies show that interfering with moral judgment by engaging subjects with a cognitive task slows down (though it does not reverse) utilitarian judgment, but has no effect on deontological judgment. Again, in agreement with the conclusion that the first type of modality is the result of cognition, the latter of emotion.
  • Nice to know, by the way, that when experimenters controlled for "real world expectations" that people have about trolleys, or when they used more realistic scenarios than trolleys and bridges, the results don't vary. In other words, trolley thought experiments are actually informative, contrary to popular criticisms.
  • What factors affect people's decision making in moral judgment? The main one is proximity, with people feeling much stronger obligations if they are present to the event posing the dilemma, or even relatively near (a disaster happens in a nearby country), as opposed to when they are far (a country on the other side of the world).
  • Greene's general conclusion is that neuroscience matters to ethics because it reveals the hidden mechanisms of human moral decision making. However, he says this is interesting to philosophers because it may lead to question ethical theories that are implicitly or explicitly based on such judgments. But neither philosophical deontology nor consequentialism are in fact based on common moral judgments, seems to me. They are the result of explicit analysis. (Though Greene raises the possibility that some philosophers engage in rationalizing, rather than reason, as in Kant's famously convoluted idea that masturbation is wrong because one is using oneself as a mean to an end...)
  • this is not to say that understanding moral decision making in humans isn't interesting or in fact even helpful in real life cases. An example of the latter is the common moral condemnation of incest, which is an emotional reaction that probably evolved to avoid genetically diseased offspring. It follows that science can tell us that three is nothing morally wrong in cases of incest when precautions have been taken to avoid pregnancy (and assuming psychological reactions are also accounted for). Greene puts this in terms of science helping us to transform difficult ought questions into easier ought questions.

Online Science Blog Gender

shared by Weiye Loh on 30 Jan 11 - No Cached
  • Mendick, H. and Moreau, M. (2010). Monitoring the presence and representation of  women in SET occupations in UK based online media. Bradford: The UKRC.
  • Mendick and Moreau considered the representation of women on eight ‘SET’ (science, engineering and technology) websites: New Scientist, Bad Science, the Science Museum, the Natural History Museum, Neuroskeptic, Science: So What, Watt’s Up With That and RichardDawkins.net. They also monitored SET content across eight more general sites: the BBC, Channel 4, Sky, the Guardian, the Daily Mail, Wikipedia, YouTube and Twitter.
  • Their results suggest online science informational content is male dominated in that far more men than women are present. On some websites, they found no SET women. All of the 14 people in SET identified on the sampled pages of the RichardDawkins.net website were men, and so were all 29 of those mentioned on the sampled pages of the Channel 4 website (Mendick & Moreau, 2010: 11).
  • ...8 more annotations...
  • They found less hyperlinking of women’s than men’s names (Mendick & Moreau, 2010: 7). Personally, I’d have really liked some detail as to how they came up with this, and what constituted ‘hyperlinking of women’s names’ precisely. It’s potentially an interesting finding, but I can’t quite get a grip on what they are saying.
  • They also note that the women that did appear, they were often peripheral to the main story, or ‘subject to muting’ (i.e. seen but not heard). They also noted many instances where women were pictured but remain anonymous, as if there are used to illustrate a piece – for ‘ornamental’ purposes – and give the example of the wikipedia entry on scientists, which includes a picture a women as an example, but stress she is anonymous (Mendick & Moreau, 2010: 12).
  • Echoing findings of earlier research on science in the media (e.g. the Bimbo or Boffin paper), they noted that women, when represented, tended to be associated with ‘feminine’ attributes and activities, demonstrating empathy with children and animals, etc. They also noted a clustering in specific fields. For example, in the pages they’d sampled of the Guardian, they found seven mentions of women scientists compared with twenty-eight of men, and three of the these women were in a single article, about Jane Goodall (Mendick & Moreau, 2010: 12-13).
  • The women presented were often discussed in terms of appearance, personality, sexuality and personal circumstances, again echoing previous research. They also noted that women scientists, when present, tended to be younger than the men, and there was a striking lack of ethnic diversity (Mendick & Moreau, 2010: 14).
  • I’m going to be quite critical of this research. It’s not actively bad, it just seems to lack depth and precision. I suspect Mendick and Moreau were doing their best with low resources and an overly-broad brief. I also think that we are still feeling our way in terms of working out how to study online science media, and so can learn something from such a critique.
  • Problem number one: it’s a small study, and yet a ginormous topic. I’d much rather they had looked at less, but made more of it. At times I felt like I was reading a cursory glance at online science.
  • Problem number two: the methodological script seemed a bit stuck in the print era. I felt the study lacked a feel for the variety of routes people take through online science. It lacked a sense of online science’s communities and cliques, its cultures and sub-cultures, its history and its people. It lacked context. Most of all, it lacked a sense of what I think sits at the center of online communication: the link.
  • It tries to look at too much, too quickly. We’re told that of the blog entries sampled from Bad Science, three out of four of the women mentioned were associated with ‘bad science’, compared to 12 out of 27 of the men . They follow up this a note that Goldacre has appeared on television critiquing Greenfield,­ a clip of which is on his site (Mendick & Moreau, 2010: 17-18). OK, but ‘bad’ needs unpacking here, as does the gendered nature of the area Goldacre takes aim at. As for Susan Greenfield, she is a very complex character when it comes to the politics of science and gender (one I’d say it is dangerous to treat representations of simplistically). Moreover, this is a very small sample, without much feel for the broader media context the Bad Science blog works within, including not only other platforms for Ben Goldacre’s voice but comment threads, forums and a whole community of other ‘bad science bloggers’ (and their relationships with each other)

Climate Science media bias Newspaper

shared by Weiye Loh on 12 Feb 11 - No Cached
  • Writing in the WSJ Europe this week Anne Jolis had a piece on extreme weather events that quotes me, and unfortunately the terse quote is missing some context that is apparently leading to some confusion.
  • I spoke with Jolis at length and she asked very good questions and expressed a desire to get the science right. She even called me back to confirm how I was to be quoted. Unfortunately the longer quote was abbreviated, which Jolis warned was always possible.  I do not view this as a particularly big deal, but since I am being asked about it via email by a few folks, here is what the quote said and how it should be: "There's no data-driven answer yet to the question of how human activity has affected extreme weather," adds Roger Pielke Jr., another University of Colorado climate researcher. Instead it would be more precise to read: "There's no data-driven answer yet to the question of how human activity has affected extreme weather disasters," adds Roger Pielke Jr., another University of Colorado climate researcher.
  • given the context of the article the implication should be abundantly clear that in the quote I am not referring to daily temperature records, Arctic ice melt or global average surface temperatures or precipitation. The quote refers directly to recent extreme events with large societal impacts around the world that are explicitly mentioned in the piece such as Cyclone Yasi, the Australian floods, Europe's cold winter and the Russian drought.  Of course, in the climate debate, anything that can be misinterpreted usually will be.

Science Religion Faith Funding Academic Academic Research

shared by Weiye Loh on 18 Feb 11 - No Cached
  • The Templeton Foundation claims to be a friend of science. So why does it make so many researchers uneasy?
  • With a current endowment estimated at US$2.1 billion, the organization continues to pursue Templeton's goal of building bridges between science and religion. Each year, it doles out some $70 million in grants, more than $40 million of which goes to research in fields such as cosmology, evolutionary biology and psychology.
  • however, many scientists find it troubling — and some see it as a threat. Jerry Coyne, an evolutionary biologist at the University of Chicago, Illinois, calls the foundation "sneakier than the creationists". Through its grants to researchers, Coyne alleges, the foundation is trying to insinuate religious values into science. "It claims to be on the side of science, but wants to make faith a virtue," he says.
  • ...25 more annotations...
  • But other researchers, both with and without Templeton grants, say that they find the foundation remarkably open and non-dogmatic. "The Templeton Foundation has never in my experience pressured, suggested or hinted at any kind of ideological slant," says Michael Shermer, editor of Skeptic, a magazine that debunks pseudoscience, who was hired by the foundation to edit an essay series entitled 'Does science make belief in God obsolete?'
  • The debate highlights some of the challenges facing the Templeton Foundation after the death of its founder in July 2008, at the age of 95.
  • With the help of a $528-million bequest from Templeton, the foundation has been radically reframing its research programme. As part of that effort, it is reducing its emphasis on religion to make its programmes more palatable to the broader scientific community. Like many of his generation, Templeton was a great believer in progress, learning, initiative and the power of human imagination — not to mention the free-enterprise system that allowed him, a middle-class boy from Winchester, Tennessee, to earn billions of dollars on Wall Street. The foundation accordingly allocates 40% of its annual grants to programmes with names such as 'character development', 'freedom and free enterprise' and 'exceptional cognitive talent and genius'.
  • Unlike most of his peers, however, Templeton thought that the principles of progress should also apply to religion. He described himself as "an enthusiastic Christian" — but was also open to learning from Hinduism, Islam and other religious traditions. Why, he wondered, couldn't religious ideas be open to the type of constructive competition that had produced so many advances in science and the free market?
  • That question sparked Templeton's mission to make religion "just as progressive as medicine or astronomy".
  • Early Templeton prizes had nothing to do with science: the first went to the Catholic missionary Mother Theresa of Calcutta in 1973.
  • By the 1980s, however, Templeton had begun to realize that fields such as neuroscience, psychology and physics could advance understanding of topics that are usually considered spiritual matters — among them forgiveness, morality and even the nature of reality. So he started to appoint scientists to the prize panel, and in 1985 the award went to a research scientist for the first time: Alister Hardy, a marine biologist who also investigated religious experience. Since then, scientists have won with increasing frequency.
  • "There's a distinct feeling in the research community that Templeton just gives the award to the most senior scientist they can find who's willing to say something nice about religion," says Harold Kroto, a chemist at Florida State University in Tallahassee, who was co-recipient of the 1996 Nobel Prize in Chemistry and describes himself as a devout atheist.
  • Yet Templeton saw scientists as allies. They had what he called "the humble approach" to knowledge, as opposed to the dogmatic approach. "Almost every scientist will agree that they know so little and they need to learn," he once said.
  • Templeton wasn't interested in funding mainstream research, says Barnaby Marsh, the foundation's executive vice-president. Templeton wanted to explore areas — such as kindness and hatred — that were not well known and did not attract major funding agencies. Marsh says Templeton wondered, "Why is it that some conflicts go on for centuries, yet some groups are able to move on?"
  • Templeton's interests gave the resulting list of grants a certain New Age quality (See Table 1). For example, in 1999 the foundation gave $4.6 million for forgiveness research at the Virginia Commonwealth University in Richmond, and in 2001 it donated $8.2 million to create an Institute for Research on Unlimited Love (that is, altruism and compassion) at Case Western Reserve University in Cleveland, Ohio. "A lot of money wasted on nonsensical ideas," says Kroto. Worse, says Coyne, these projects are profoundly corrupting to science, because the money tempts researchers into wasting time and effort on topics that aren't worth it. If someone is willing to sell out for a million dollars, he says, "Templeton is there to oblige him".
  • At the same time, says Marsh, the 'dean of value investing', as Templeton was known on Wall Street, had no intention of wasting his money on junk science or unanswerables such as whether God exists. So before pursuing a scientific topic he would ask his staff to get an assessment from appropriate scholars — a practice that soon evolved into a peer-review process drawing on experts from across the scientific community.
  • Because Templeton didn't like bureaucracy, adds Marsh, the foundation outsourced much of its peer review and grant giving. In 1996, for example, it gave $5.3 million to the American Association for the Advancement of Science (AAAS) in Washington DC, to fund efforts that work with evangelical groups to find common ground on issues such as the environment, and to get more science into seminary curricula. In 2006, Templeton gave $8.8 million towards the creation of the Foundational Questions Institute (FQXi), which funds research on the origins of the Universe and other fundamental issues in physics, under the leadership of Anthony Aguirre, an astrophysicist at the University of California, Santa Cruz, and Max Tegmark, a cosmologist at the Massachusetts Institute of Technology in Cambridge.
  • But external peer review hasn't always kept the foundation out of trouble. In the 1990s, for example, Templeton-funded organizations gave book-writing grants to Guillermo Gonzalez, an astrophysicist now at Grove City College in Pennsylvania, and William Dembski, a philosopher now at the Southwestern Baptist Theological Seminary in Fort Worth, Texas. After obtaining the grants, both later joined the Discovery Institute — a think-tank based in Seattle, Washington, that promotes intelligent design. Other Templeton grants supported a number of college courses in which intelligent design was discussed. Then, in 1999, the foundation funded a conference at Concordia University in Mequon, Wisconsin, in which intelligent-design proponents confronted critics. Those awards became a major embarrassment in late 2005, during a highly publicized court fight over the teaching of intelligent design in schools in Dover, Pennsylvania. A number of media accounts of the intelligent design movement described the Templeton Foundation as a major supporter — a charge that Charles Harper, then senior vice-president, was at pains to deny.
  • Some foundation officials were initially intrigued by intelligent design, Harper told The New York Times. But disillusionment set in — and Templeton funding stopped — when it became clear that the theory was part of a political movement from the Christian right wing, not science. Today, the foundation website explicitly warns intelligent-design researchers not to bother submitting proposals: they will not be considered.
  • Avowedly antireligious scientists such as Coyne and Kroto see the intelligent-design imbroglio as a symptom of their fundamental complaint that religion and science should not mix at all. "Religion is based on dogma and belief, whereas science is based on doubt and questioning," says Coyne, echoing an argument made by many others. "In religion, faith is a virtue. In science, faith is a vice." The purpose of the Templeton Foundation is to break down that wall, he says — to reconcile the irreconcilable and give religion scholarly legitimacy.
  • Foundation officials insist that this is backwards: questioning is their reason for being. Religious dogma is what they are fighting. That does seem to be the experience of many scientists who have taken Templeton money. During the launch of FQXi, says Aguirre, "Max and I were very suspicious at first. So we said, 'We'll try this out, and the minute something smells, we'll cut and run.' It never happened. The grants we've given have not been connected with religion in any way, and they seem perfectly happy about that."
  • John Cacioppo, a psychologist at the University of Chicago, also had concerns when he started a Templeton-funded project in 2007. He had just published a paper with survey data showing that religious affiliation had a negative correlation with health among African-Americans — the opposite of what he assumed the foundation wanted to hear. He was bracing for a protest when someone told him to look at the foundation's website. They had displayed his finding on the front page. "That made me relax a bit," says Cacioppo.
  • Yet, even scientists who give the foundation high marks for openness often find it hard to shake their unease. Sean Carroll, a physicist at the California Institute of Technology in Pasadena, is willing to participate in Templeton-funded events — but worries about the foundation's emphasis on research into 'spiritual' matters. "The act of doing science means that you accept a purely material explanation of the Universe, that no spiritual dimension is required," he says.
  • It hasn't helped that Jack Templeton is much more politically and religiously conservative than his father was. The foundation shows no obvious rightwards trend in its grant-giving and other activities since John Templeton's death — and it is barred from supporting political activities by its legal status as a not-for-profit corporation. Still, many scientists find it hard to trust an organization whose president has used his personal fortune to support right-leaning candidates and causes such as the 2008 ballot initiative that outlawed gay marriage in California.
  • Scientists' discomfort with the foundation is probably inevitable in the current political climate, says Scott Atran, an anthropologist at the University of Michigan in Ann Arbor. The past 30 years have seen the growing power of the Christian religious right in the United States, the rise of radical Islam around the world, and religiously motivated terrorist attacks such as those in the United States on 11 September 2001. Given all that, says Atran, many scientists find it almost impossible to think of religion as anything but fundamentalism at war with reason.
  • the foundation has embraced the theme of 'science and the big questions' — an open-ended list that includes topics such as 'Does the Universe have a purpose?'
  • Towards the end of Templeton's life, says Marsh, he became increasingly concerned that this reaction was getting in the way of the foundation's mission: that the word 'religion' was alienating too many good scientists.
  • The peer-review and grant-making system has also been revamped: whereas in the past the foundation ran an informal mix of projects generated by Templeton and outside grant seekers, the system is now organized around an annual list of explicit funding priorities.
  • The foundation is still a work in progress, says Jack Templeton — and it always will be. "My father believed," he says, "we were all called to be part of an ongoing creative process. He was always trying to make people think differently." "And he always said, 'If you're still doing today what you tried to do two years ago, then you're not making progress.'"

Homeopathy Science Medicine Health News

shared by Weiye Loh on 22 Feb 11 - No Cached
  • The 10:23 demonstrations and the CBC Marketplace coverage have elicited fascinating case studies in CAM professionalism. Rather than offering any new information or evidence about homeopathy itself, some homeopaths have spuriously accused skeptical groups of being malicious Big Pharma shills.
  • Mike Adams of the Natural News website
  • has decided to provide his own coverage of the 10:23 campaign
  • ...17 more annotations...
  • Mike’s thesis is essentially: Silly skeptics, it’s impossible to OD on homeopathy!
  • 1. “Notice that they never consume their own medicines in large doses? Chemotherapy? Statin drugs? Blood thinners? They wouldn’t dare drink those.
  • Of course we wouldn’t. Steven Novella rightly points out that, though Mike thinks he’s being clever here, he’s actually demonstrating a lack of understanding for what the 10:23 campaign is about by using a straw man. Mike later issues a challenge for skeptics to drink their favourite medicines while he drinks homeopathy. Since no one will agree to that for the reasons explained above, he can claim some sort of victory — hence his smugness. But no one is saying that drugs aren’t harmful.
  • The difference between medicine and poison is in the dose. The vitamins and herbs promoted by the CAM industry are just as potentially harmful as any pharmaceutical drug, given enough of it. Would Adams be willing to OD on the vitamins or herbal remedies that he sells?
  • Even Adams’ favorite panacea, vitamin D, is toxic if you take enough of it (just ask Gary Null). Notice how skeptics don’t consume those either, because that is not the point they’re making.
  • The point of these demonstrations is that homeopathy has nothing in it, has no measurable physiological effects, and does not do what is advertised on the package.
  • 2. “Homeopathy, you see, isn’t a drug. It’s not a chemical.” Well, he’s got that right. “You know the drugs are kicking in when you start getting worse. Toxicity and conventional medicine go hand in hand.” [emphasis his]
  • Here I have to wonder if Adams knows any people with diabetes, AIDS, or any other illness that used to mean a death sentence before the significant medical advances of the 20th century that we now take for granted. So far he seems to be a firm believer in the false dichotomy that drugs are bad and natural products are good, regardless of what’s in them or how they’re used (as we know, natural products can have biologically active substances and effectively act as impure drugs – but leave it to Adams not to get bogged down with details). There is nothing to support the assertion that conventional medicine is nothing but toxic symptom-inducers.
  • 3-11. “But homeopathy isn’t a chemical. It’s a resonance. A vibration, or a harmony. It’s the restructuring of water to resonate with the particular energy of a plant or substance. We can get into the physics of it in a subsequent article, but for now it’s easy to recognize that even from a conventional physics point of view, liquid water has tremendous energy, and it’s constantly in motion, not just at the molecular level but also at the level of its subatomic particles and so-called “orbiting electrons” which aren’t even orbiting in the first place. Electrons are vibrations and not physical objects.” [emphasis his]
  • This is Star Trek-like technobabble – lots of sciency words
  • if something — anything — has an effect, then that effect is measurable by definition. Either something works or it doesn’t, regardless of mechanism. In any case, I’d like to see the well-documented series of research that conclusively proves this supposed mechanism. Actually, I’d like to see any credible research at all. I know what the answer will be to that: science can’t detect this yet. Well if you agree with that statement, reader, ask yourself this: then how does Adams know? Where did he get this information? Without evidence, he is guessing, and what is that really worth?
  • 13. “But getting back to water and vibrations, which isn’t magic but rather vibrational physics, you can’t overdose on a harmony. If you have one violin playing a note in your room, and you add ten more violins — or a hundred more — it’s all still the same harmony (with all its complex higher frequencies, too). There’s no toxicity to it.” [emphasis his]
  • Homeopathy has standard dosing regimes (they’re all the same), but there is no “dose” to speak of: the ingredients have usually been diluted out to nothing. But Adams is also saying that homeopathy doesn’t work by dose at all, it works by the properties of “resonance” and “vibration”. Then why any dosing regimen? To maintain the resonance? How is this resonance measured? How long does the “resonance” last? Why does it wear off? Why does he think televisions can inactivate homeopathy? (I think I might know the answer to that last one, as electronic interference is a handy excuse for inefficacy.)
  • “These skeptics just want to kill themselves… and they wouldn’t mind taking a few of you along with them, too. Hence their promotion of vaccines, pharmaceuticals, chemotherapy and water fluoridation. We’ll title the video, “SKEPTICS COMMIT MASS SUICIDE BY DRINKING PHARMACEUTICALS AS IF THEY WERE KOOL-AID.” Jonestown, anyone?”
  • “Do you notice the irony here? The only medicines they’re willing to consume in large doses in public are homeopathic remedies! They won’t dare consume large quantities of the medicines they all say YOU should be taking! (The pharma drugs.)” [emphasis his]
  • what Adams seems to have missed is that the skeptics have no intention of killing themselves, so his bizarre claims that the 10:23 participants are psychopathic, self-loathing, and suicidal makes not even a little bit of sense. Skeptics know they aren’t going to die with these demonstrations, because homeopathy has no active ingredients and no evidence of efficacy.
  • The inventor of homeopathy himself, Samuel Hahnemann believed that excessive doses of homeopathy could be harmful (see sections 275 and 276 of his Organon). Homeopaths are pros at retconning their own field to fit in with Hahnemann’s original ideas (inventing new mechanisms, such as water memory and resonance, in the face of germ theory). So how does Adams reconcile this claim?

  • website PatientsLikeMe.com noticed suspicious activity on its "Mood" discussion board. There, people exchange highly personal stories about their emotional disorders, ranging from bipolar disease to a desire to cut themselves. It was a break-in. A new member of the site, using sophisticated software, was "scraping," or copying, every single message off PatientsLikeMe's private online forums.
  • PatientsLikeMe managed to block and identify the intruder: Nielsen Co., the privately held New York media-research firm. Nielsen monitors online "buzz" for clients, including major drug makers, which buy data gleaned from the Web to get insight from consumers about their products, Nielsen says.
  • The market for personal data about Internet users is booming, and in the vanguard is the practice of "scraping." Firms offer to harvest online conversations and collect personal details from social-networking sites, résumé sites and online forums where people might discuss their lives. The emerging business of web scraping provides some of the raw material for a rapidly expanding data economy. Marketers spent $7.8 billion on online and offline data in 2009, according to the New York management consulting firm Winterberry Group LLC. Spending on data from online sources is set to more than double, to $840 million in 2012 from $410 million in 2009.
  • ...6 more annotations...
  • The Wall Street Journal's examination of scraping—a trade that involves personal information as well as many other types of data—is part of the newspaper's investigation into the business of tracking people's activities online and selling details about their behavior and personal interests.
  • Some companies collect personal information for detailed background reports on individuals, such as email addresses, cell numbers, photographs and posts on social-network sites. Others offer what are known as listening services, which monitor in real time hundreds or thousands of news sources, blogs and websites to see what people are saying about specific products or topics.
  • One such service is offered by Dow Jones & Co., publisher of the Journal. Dow Jones collects data from the Web—which may include personal information contained in news articles and blog postings—that help corporate clients monitor how they are portrayed. It says it doesn't gather information from password-protected parts of sites.
  • The competition for data is fierce. PatientsLikeMe also sells data about its users. PatientsLikeMe says the data it sells is anonymized, no names attached.
  • Nielsen spokesman Matt Anchin says the company's reports to its clients include publicly available information gleaned from the Internet, "so if someone decides to share personally identifiable information, it could be included."

    data shows that in 2010 the world saw the rate of change in its carbon dioxide emissions per unit of economic activity continue to decrease -- to zero.  (The data that I use are global GDP data from Angus Maddison extended using IMF global GDP growth rates and NEAA carbon dioxide data extended to 2010 using the 2010 growth rate released by the IEA yesterday).  The deceleration of the decarbonization of the global economy means that the world is moving away from stabilization of concentrations of carbon dioxide in the atmosphere, and despite the various reports issued and assertions made, there is no evidence to support claims to the contrary.

Genetic Nature Nurture Diversity

  • One of the complications is that the effective environment is defined by the life activities of the organism itself.
  • Thus, as organisms evolve, their environments necessarily evolve with them. Although classic Darwinism is framed by referring to organisms adapting to environments, the actual process of evolution involves the creation of new “ecological niches” as new life forms come into existence. Part of the ecological niche of an earthworm is the tunnel excavated by the worm and part of the ecological niche of a tree is the assemblage of fungi associated with the tree’s root system that provide it with nutrients.
  • , the distinction between organisms and their environments remains deeply embedded in our consciousness. Partly this is due to the inertia of educational institutions and materials
  • ...7 more annotations...
  • But the problem is deeper than simply intellectual inertia. It goes back, ultimately, to the unconsidered differentiations we make—at every moment when we distinguish among objects—between those in the foreground of our consciousness and the background places in which the objects happen to be situated. Moreover, this distinction creates a hierarchy of objects. We are conscious not only of the skin that encloses and defines the object, but of bits and pieces of that object, each of which must have its own “skin.” That is the problem of anatomization. A car has a motor and brakes and a transmission and an outer body that, at appropriate moments, become separate objects of our consciousness, objects that at least some knowledgeable person recognizes as coherent entities.
  • Evelyn Fox Keller sees “The Mirage of a Space Between Nature and Nurture” as a consequence of our false division of the world into living objects without sufficient consideration of the external milieu in which they are embedded, since organisms help create effective environments through their own life activities.
  • The central point of her analysis has been that gender itself (as opposed to sex) is socially constructed, and that construction has influenced the development of science:If there is a single point on which all feminist scholarship…has converged, it is the importance of recognizing the social construction of gender…. All of my work on gender and science proceeds from this basic recognition. My endeavor has been to call attention to the ways in which the social construction of a binary opposition between “masculine” and “feminine” has influenced the social construction of science.
  • major critical concern of Fox Keller’s present book is the widespread attempt to partition in some quantitative way the contribution made to human variation by differences in biological inheritance, that is, differences in genes, as opposed to differences in life experience. She wants to make clear a distinction between analyzing the relative strength of the causes of variation among individuals and groups, an analysis that is coherent in principle, and simply assigning the relative contributions of biological and environmental causes to the value of some character in an individual
  • It is, for example, all very well to say that genetic variation is responsible for 76 percent of the observed variation in adult height among American women while the remaining 24 percent is a consequence of differences in nutrition. The implication is that if all variation in nutrition were abolished then 24 percent of the observed height variation among individuals in the population in the next generation would disappear. To say, however, that 76 percent of Evelyn Fox Keller’s height was caused by her genes and 24 percent by her nutrition does not make sense. The nonsensical implication of trying to partition the causes of her individual height would be that if she never ate anything she would still be three quarters as tall as she is.
  • In fact, Keller is too optimistic about the assignment of causes of variation even when considering variation in a population. As she herself notes parenthetically, the assignment of relative proportions of population variation to different causes in a population depends on there being no specific interaction between the causes.
  • Keller’s rather casual treatment of the interaction between causal factors in the case of the drummers, despite her very great sophistication in analyzing the meaning of variation, is a symptom of a fault that is deeply embedded in the analytic training and thinking of both natural and social scientists. If there are several variable factors influencing some phenomenon, how are we to assign the relative importance to each in determining total variation? Let us take an extreme example. Suppose that we plant seeds of each of two different varieties of corn in two different locations with the following results measured in bushels of corn produced (see Table 1). There are differences between the varieties in their yield from location to location and there are differences between locations from variety to variety. So, both variety and location matter. But there is no average variation between locations when averaged over varieties or between varieties when averaged over locations. Just by knowing the variation in yield associated with location and variety separately does not tell us which factor is the more important source of variation; nor do the facts of location and variety exhaust the description of that variation.

    In trying to analyze the natural world, scientists are seldom aware of the degree to which their ideas are influenced both by their way of perceiving the everyday world and by the constraints that our cognitive development puts on our formulations. At every moment of perception of the world around us, we isolate objects as discrete entities with clear boundaries while we relegate the rest to a background in which the objects exist.

    The video takes Bill Mckibben's recent editorial from the Washington Post, sets it to music and powerful video of the last year's weather events. If you haven't seen the editorial, give that a look first. It starts out - Caution: It is vitally important not to make connections. When you see pictures of rubble like this week's shots from Joplin, Mo., you should not wonder: Is this somehow related to the tornado outbreak three weeks ago in Tuscaloosa, Ala., or the enormous outbreak a couple of weeks before that (which, together, comprised the most active April for tornadoes in U.S. history). No, that doesn't mean a thing. It is far better to think of these as isolated, unpredictable, discrete events. It is not advisable to try to connect them in your mind with, say, the fires burning across Texas - fires that have burned more of America at this point this year than any wildfires have in previous years. Texas, and adjoining parts of Oklahoma and New Mexico, are drier than they've ever been - the drought is worse than that of the Dust Bowl. But do not wonder if they're somehow connected.

Journalism Privacy Ethics

  • Journalism is demonstrably valuable to society. It tells us what is new, important and interesting in public life, it holds authority to account, it promotes informed debate, it entertains and enlightens. For sure, it comes with complications. It is rushed and imperfect, it sometimes upsets people and in pursuit of its objectives it occasionally does unpleasant or even illegal things. But by and large we accept these less welcome aspects of journalism as part of the package, and we do so because journalism as a whole is in the public interest. It does good, or to put it another way, we would be much poorer without it.
  • journalists themselves are slow to draw the distinction because theirs is traditionally an open industry, without barriers and categories, and also because they don’t tend to think of what they do in terms of doing good and being valuable.
  • privacy invaders do everything they can to blur the line. It is in their interest to be considered journalists, after all. They can shelter under the same umbrella and enjoy the same privileges as journalists. They can talk about freedom of expression, freedom of the press and serving the public interest; they can appeal to tradition and history and they can sound warnings about current and future censorship. This helps them to protect what they do.

  • The public interest is central because it is a sort of get-out-of-jail card for journalists, though it is actually recognised only grudgingly in law. An ethical journalist can justify telling a lie, or covertly recording a conversation, or trespassing if this act is done in the pursuit of the public interest, and even if he or she is found guilty of an offence, others will usually understand this as valid and will give their support. The public interest can literally keep a journalist out of jail, and it is not merely in the eye of the beholder. The Press Complaints Commission, for example, defines it as follows: The public interest includes, but is not confined to: i) Detecting or exposing crime or serious impropriety ii) Protecting public health and safety iii) Preventing the public from being misled by an action or statement of an individual or organisation

    We tend to speak of journalists, of their role, their rights, their responsibilities and very often their lack of restraint and how it should be addressed. But this is misleading, and prevents us from seeing some of the complexities and possibilities, because the word 'journalist', in this context, covers two very different groups of people. One group is the actual journalists, as traditionally understood, and the other is those people whose principal professional activity is invading other people's privacy for the purpose of publication.

    THE ETHICAL PROBLEM: Allowing someone to die, mercy death, and mercy killing, Euthanasia: A 24-year-old man named Robert who has a wife and child is paralyzed from the neck down in a motorcycle accident. He has always been very active and hates the idea of being paralyzed. He also is in a great deal of pain, an he has asked his doctors and other members of his family to "put him out of his misery." After several days of such pleading, his brother comes into Robert's hospital ward and asks him if he is sure he still wants to be put out of his misery. Robert says yes and pleads with his brother to kill him. The brother kisses and blesses Robert, then takes out a gun and shoots him, killing him instantly. The brother later is tried for murder and acquitted by reason of temporary insanity. Was what Robert's brother did moral? Do you think he should have been brought to trial at all? Do you think he should have been acquitted? Would you do the same for a loved one if you were asked? THE DISCUSSION: In my opinion, the most dubious part about the case would be the part on Robert pleading with his brother, asking his brother to kill him. This could be his brother's own account of the incident and could/could not have been a plea by Robert. 1) With assumption that Robert indeed pleaded with his brother to kill him, an ethical analysis as such could be derived: That Robert's brother was only respecting Robert's choice and killed him because he wanted to relieve him from his misery. This could be argued to be ethical using a teleoloigical framework where the focus is on the end-result and the consequences that entails the action. Here, although the act of killing per se may be wrong and illegal, Robert was able to relieved of his pain and suffering. 2) With an assumption that Robert did not plea with his brother to kill him and that it was his brother's own decision to relieve Robert of all-suffering: In this case, the b

    I find euthanasia to be a very interesting ethical dilemma. Even I myself am caught in the middle. Euthanasia has been termed as 'mercy killing' and even 'happy death'. Others may simply just term it as being 'evil'. Is it right to end someone's life even when he or she pleads you to do so? In the first place, is it even right to commit suicide? Once someone pulls off the main support that's keeping the person alive, such as the feeding tube, there is no turning back. Hmm..Come to think of it, technology is kind of unethical by being made available, for in the past, when someone is dying, they had the right to die naturally. Now, scientific technology is 'forcing' us to stay alive and cling on to a life that may be deemed being worthless if we were standing outside our bodies looking at our comatose selves. Then again, this may just be MY personal standpoint. But I have to argue, who gave technology the right to make me a worthless vegetable!(and here I am, attaching a value/judgement onto an immobile human being..) Hence, being incompetent in making decisions for my unconscious self (or perhaps even brain dead), who should take responsibility for my life, for my existence? And on what basis are they allowed to help me out? Taking the other side of the argument, against euthanasia, we can say that the act of ending someone else's life is the act of destroying societal respect for life. Based on the utilitarian perspective, we are not thinking of the overall beneficence for society and disregarding the moral considerations encompassed within the state's interest to preserve the sanctity of all life. It has been said that life in itself takes priority over all other values. We should let the person live so as to give him/her a chance to wake up or hope for recovery (think comatose patients). But then again we can also argue that life is not the top of the hierarchy! A life without rights is as if not living a life at all? By removing the patient

    as a human being, you supposedly have a right to live, whether you are mobile or immobile. however, i think that, in the case of euthanasia, you 'give up' your rights when you "show" that you are no longer able to serve the pre-requisites of having the right. for example, if "living" rights are equate to you being able to talk, walk, etc etc, then, obviously the opposite means you no longer are able to perform up to the expectations of that right. then again, it is very subjective as to who gets to make that criteria!
  • Magdaleine on 02 Nov 09
     
    hmm interesting.. however, a question i have is who and when can this "right" be "given up"? when i am a victim in a car accident, and i lost the ability to breathe, walk and may need months to recover. i am unconscious and the doctor is unable to determine when am i gonna regain consciousness. when should my parents decide i can no longer be able to have any living rights? and taking elaine's point into consideration, is committing suicide even 'right'? if it is legally not right, when i ask someone to take my life and wrote a letter that it was cus i wanted to die, does that make it committing suicide only in the hands of others?
  • Low Yunying on 04 Nov 09
     
    Similarly, I question the 'rights' that you have to 'give up' when you no longer 'serve the pre-requisites of having the right'. If the living rights means being able to talk and walk, then where does it leave infants? Where does it leave people who may be handicapped? Have their lost their rights to living?

  • LONDON - Scientific advances including techniques allowing patients to grow new joints inside their own bodies will allow the elderly to remain active well beyond their 100th birthdays, researchers claim. British scientists are working on a system which should allow the elderly to buy body parts "off the shelf" and even regenerate their own damaged joints and hearts. Their ultimate aim is to fix up the body with customised replacement parts grown to order. They have already carried out human trials on heart valves which are still working four years after they were transplanted. At the University of Leeds, Britain's biggest bioengineering unit and the world leader in artificial joint replacement research is coordinating a project that aims to give people 50 active years after the age of 50."It is the rise of the bionic pensioner," said Professor Christina Doyle, whose company is working with the university to develop the new technologies. "The idea is when something wears out, your surgeon can buy a replacement off the shelf or, more accurately, in a bag."The university is spending £50 million ($114 million) over the next five years on the new project. The main thrust of the research centres on a method of tissue and medical engineering which the university is at the forefront of developing. Led by the immunologist Professor Eileen Ingham, they are pioneering a technique of stripping the living cells from donor human and animal parts, leaving just the collagen or elastin "scaffold" of the tissue. These "biological shells", which could be for knee, ankle or hip ligaments, as well as blood vessels and heart valves, are then transplanted into the patient whose own body then invades them replacing the removed cells with their own. The technique, which could be available within five years, effectively removes the need for anti-rejection drugs. It is similar to the recently developed system of using stem cells to regrow organs outside the body, but costs about a tenth of the price.

Pollution Cancer Policy Science Risk

  • One of the big misconceptions is that artificial chemicals such as pesticides have a lot to do with human cancer, but that's just not true," says Bruce N. Ames, professor of biochemistry and molecular biology at the University of California at Berkeley and co-author of a new review of what is known about environmental pollution and cancer. "Nevertheless, it's conventional wisdom and society spends billions on this each year." "We consume more carcinogens in one cup of coffee than we get from the pesticide residues on all the fruits and vegetables we eat in a year," he adds.
  • there may be many excellent reasons for cleaning up pollution of our air, water and soil, the researchers say, prevention of cancer is not one of them.
  • "The problem is that lifestyle changes are tough," says Gold, director of the Carcinogenic Potency Project at UC Berkeley's National Institute for Environmental Health Sciences Center and a senior scientist in the cell and molecular biology division at Lawrence Berkeley National Laboratory. "But by targeting pesticide residues as a major problem, we risk making fruits and vegetables more expensive and indirectly increasing cancer risks, especially among the poor."
  • ...10 more annotations...
  • Whereas 99.9 percent of all the chemicals we ingest are natural, 78 percent of the chemicals tested are synthetic. So when more than half of all synthetic chemicals are found to cause cancer in rodents, it's not surprising that people link cancer with synthetic chemicals. But of the natural chemicals in our diet that have been tested in animals, half also cause cancer, Gold says.
  • "We need to recognize that there are far more carcinogens in the natural world than in the synthetic world, and go after the important things, such as lifestyle change."
  • Misconception: Cancer rates are soaring. In fact, the researchers say, if lung cancer due to smoking is excluded, overall cancer deaths in the U.S. have declined 16 percent since 1950.
  • Misconception: Reducing pesticide residues is an effective way to prevent diet-related cancer. Because fruits and vegetables are of major importance in reducing cancer, the unintended effect of requiring expensive efforts to reduce the amount of pesticides remaining on fruits and vegetables will be to increase their cost. This will lead to an increase in cancer among low income people who no longer will be able to afford to eat them.
  • Misconception: Human exposures to carcinogens and other potential hazards are primarily due to synthetic chemicals. Americans actually eat about 10,000 times more natural pesticides from fruits and vegetables than synthetic pesticide residues on food. Natural pesticides are chemicals that plants produce to defend themselves against fungi, insects, and other predators. And half of all natural pesticides tested in rodents turn out to be rodent carcinogens. In addition, we consume many other carcinogens in foods because of the chemicals produced in cooking. In a single cup of roasted coffee, for example, the natural chemicals known to be rodent carcinogens are about equal in weight to an entire year's work of synthetic pesticide residues.
  • Misconception: Cancer risks to humans can be assessed by standard high-dose animal cancer tests. In cancer tests, animals are given very high, nearly toxic doses. The effect on humans at lower doses is extrapolated from these results, as if the relationship were a straight line from high dose to low dose. However, the fact that half of all chemicals tested, whether natural or synthetic, turn out to cause cancer in rodents implies that this is an artifact of using high doses. High doses of any chemical can chronically kill cells and wound tissue, a risk factor for cancer . "Our conclusion is that the scientific evidence shows that there are high-dose effects," Ames says. "But even though government regulatory agencies recognize this, they still decide which synthetic chemicals to regulate based on linear extrapolation of high dose cancer tests in animals."
  • Misconception: Synthetic chemicals pose greater carcinogenic hazards than natural chemicals. Naturally occurring carcinogens represent an enormous background compared to the low-dose exposures to residues of synthetic chemicals such as pesticides, the researchers conclude. These results call for a reevaluation of whether animal cancer tests are really useful guides for protecting the public against minor hypothetical risks.
  • Misconception: The toxicology of synthetic chemicals is different from that of natural chemicals. No evidence exists for this, but the assumption could lead to unfortunate tradeoffs between natural and synthetic pesticides. Recently, for example, when a new variety of highly insect-resistant celery was introduced on a farm, the workers handling the celery developed rashes when they were exposed to sunlight. The pest-resistant celery turned out to contain almost eight times more natural pesticide in the form of psoralens -- chemicals known to cause cancer and genetic mutations -- than common celery.
  • Misconception: Pesticides and other synthetic chemicals are disrupting human hormones. Claims that synthetic chemicals with hormonal activity contribute to cancer and reduced sperm count ignore the fact that natural chemicals have hormone-like activity millions of times greater than do traces of synthetic chemicals. Rather, lifestyle -- lack of exercise, obesity, alcohol use and reproductive history -- are known to lead to marked changes in hormone levels in the body.
  • Misconception: Regulating low, hypothetical risks advances public health. Society -- primarily the private sector -- will spend an estimated $140 billion to comply with environmental regulations this year, according to projections by the Environmental Protection Agency. Much of this is aimed at reducing low-level human exposure to chemicals solely because they are rodent carcinogens, despite the fact that this rationale is flawed. Our improved ability to detect even minuscule concentrations of chemicals makes regulation even more expensive.
  • Weiye Loh on 09 Apr 11
     
    BERKELEY -- Despite a lack of convincing evidence that pollution is an important cause of human cancer, this misconception drives government policy today and results in billions of dollars spent to clean up minuscule amounts of synthetic chemicals, say two UC Berkeley researchers.

Net Neutrality

shared by Weiye Loh on 30 Mar 11 - No Cached
  • debates about the nature, the architecture and the governing principles of the internet are not merely technical or economic discussions.  Above all, these debates have deep political, social, and cultural implications and become a matter of public, national and global interest.
  • In many ways, net neutrality could be considered the first amendment of the internet; no pun intended here. However, just as with freedom of speech the principle of net neutrality cannot be approached as absolute or as a fetish. Even in a democracy we cannot say everything applies all the time in all contexts. Limiting the core principle of freedom of speech in a democracy is only possible in very specific circumstances, such as harm, racism or in view of the public interest. Along the same lines, compromising on the principle of net neutrality should be for very specific and clearly defined reasons that are transparent and do not serve commercial private interests, but rather public interests or are implemented in view of guaranteeing an excellent quality of service for all.
  • One of the only really convincing arguments of those challenging net neutrality is that due to the dramatic increases in streaming activity and data-exchange through peer-to-peer networks, the overall quality of service risks being compromised if we stick to data being treated on a first come first serve basis. We are being told that popular content will need to be stored closer to the consumer, which evidently comes at an extra cost.
  • ...5 more annotations...
  • Implicitly two separate debates are being collapsed here and I would argue that we need to separate both. The first one relates to the stability of the internet as an information and communication infrastructure because of the way we collectively use that infrastructure. The second debate is whether ISPs and telecommunication companies should be allowed to differentiate in their pricing between different levels of quality of access, both towards consumers and content providers.
  • Just as with freedom of speech, circumstances can be found in which the principle while still cherished and upheld, can be adapted and constrained to some extent. To paraphrase Tim Wu (2008), the aspiration should still be ‘to treat all content, sites, and platforms equally’, but maybe some forms of content should be treated more equally than others in order to guarantee an excellent quality of service for all. However, the societal and political implications of this need to be thought through in detail and as with freedom of speech itself, it will, I believe, require strict regulation and conditions.
  • In regards to the first debate on internet stability, a case can be made for allowing internet operators to differentiate between different types of data with different needs – if for any reason the quality of service of the internet as a whole cannot be guaranteed anymore. 
  • Concerning the second debate on differential pricing, it is fair to say that from a public interest and civic liberty perspective the consolidation and institutionalization of a commercially driven two-tiered internet is not acceptable and impossible to legitimate. As is allowing operators to differentiate in the quality of provision of certain kind of content above others.  A core principle such as net neutrality should never be relinquished for the sake of private interests and profit-making strategies – on behalf of industry or for others. If we need to compromise on net neutrality it would always have to be partial, to be circumscribed and only to improve the quality of service for all, not just for the few who can afford it.
  • Separating these two debates exposes the crux of the current net-neutrality debate. In essence, we are being urged to give up on the principle of net-neutrality to guarantee a good quality of service.  However, this argument is actually a pre-text for the telecom industry to make content-providers pay for the facilitation of access to their audiences – the internet subscribers. And this again can be linked to another debate being waged amongst content providers: how do we make internet users pay for the content they access online? I won’t open that can of worms here, but I will make my point clear.  Telecommunication industry efforts to make content providers pay for access to their audiences do not offer legitimate reasons to suspend the first amendment of the internet.

  • The deeper issue at work here is an open secret in the practice of democracy, and that is the fact that our elected leaders are chosen from among us, the people.  As such, politicians tend to reflect the views of the general public on many subjects - not just those subjects governed solely by political passions, but also those that are traditionally the province of experts.  Elected officials are not just a lot like us, they are us.
  • For example, perhaps foreshadowing contemporary US politics, in 1996 a freshman member of the US Congress proposed eliminating the US government's National Weather Service , declaring that the agency was not needed because "I get my weather from The Weather Channel."  Of course the weather informaton found on The Weather Channel comes from a sophisticated scientific and technological infrastructure built by the federal government over many decades which supports a wide range of economic activity, from agriculture to airlines, as well as from the private sector weather services.

  • European politicians have their own blind spots at the interface of science and policy.  For instance, several years ago former German environment minister Sigmar Gabriel claimed rather implausibly that: "You can build 100 coal-fired power plants and don't have to have higher CO2 emissions."  His explanation was that Germany participates in emissions trading and this would necessarily limit carbon dioxide no matter how much was produced. Obviously, emissions trading cannot make the impossible possible.
  • We should expect policy makers to face difficulties when it comes to governance when it involves considerations of science, technology, and innovation for the simple reason that they are just like everyone else -- mostly ignorant about mostly everything.
  • in 2010, the US NSF reported that 28% of Americans and 34% of Europeans believed that the sun goes around the earth.  Similarly, 30% of Americans and 41% of Europeans believe that radioactivity results only from human activities.  It should not be so surprising when we learn that policy makers may share such perspectives.
  • A popular view is that more education about science and technology will lead to better decisions.  While education is, of course, important to a healthy democracy, it will never result in a populace (or their representatives) with expertise in everything.  
  • Achieving such heroic levels of expertise is not realistic for anyone.  Instead, we must rely on specialized experts to inform decision making. Just as you and I often need to consult with experts when dealing with our health, home repairs, finances, and other tasks, so too do policy makers need to tap into expertise in order to make good decisions.
  • it should be far less worrisome that the public or policy makers do not understand this or that information that experts may know well.  What should be of more concern is that policy makers appear to lack an understanding of how they can tap into expertise to inform decision making.  This situation is akin to flying blind. Specialized expertise typically does not compel particular decisions, but it does help to make decisions more informed.  This distinction lies behind Winston Churchill's oft-cited advice that science should be "on tap, but not on top." Effective governance does not depend upon philosopher kings in governments or in the populace, but rather on the use of effective mechanisms for bringing expertise into the political process.
  • It is the responsibility - even the special expertise - of policy makers to know how to use the instruments of government to bring experts into the process of governance. The troubling aspect of the statements and actions by the Gummers, Gabriels, and Bachmanns of the political world lies not in their lack of knowledge about science, but in their lack of knowledge about government.

Politics Science Activism NGO

  • In this case the NGOs and other groups represent environmental and humanitarian groups that have put together a report (in PDF) on what they see as needed and unnecessary policy actions related to climate change. They put together a nice glossy report with findings and recommendations such as: *Limit global temperature rise to 2 degrees (Celsius, p. 4) *Extracting the World Bank from fossil fuels (p. 15) *Opposing the inclusion of carbon sinks in the [Kyoto] Protocol (p. 22)
  • It is troubling that the Chair of the IPCC would lend his name and organizational affiliation to a set of groups with members engaged actively in political advocacy on climate change. Even if Dr. Pachauri feels strongly about the merit of the political agenda proposed by these groups, at a minimum his endorsement creates a potential perception that the IPCC has an unstated political agenda. This is compounded by the fact that the report Dr. Pachauri tacitly endorses contains statements that are scientifically at odds with those of the IPCC.
  • perhaps most troubling is that by endorsing this group’s agenda he has opened the door for those who would seek to discredit the IPCC by alleging exactly such a bias. (And don’t be surprised to see such statements forthcoming.) If the IPCC’s role is indeed to act as an honest broker, then it would seem to make sense that its leadership ought not blur that role by endorsing, tacitly or otherwise, the agendas of particular groups. There are plenty of appropriate places for political advocacy on climate change, but the IPCC does not seem to me to be among those places.

  • Organized by the New Economics Foundation and the Working Group on Climate and Development, the report (in PDF) is actually pretty good and contains much valuable information on climate change and development (that is, once you get past the hype of the press release and its lack of precision in disaggregating climate and vulnerability as sources of climate-related impacts). The participating organizations have done a nice job integrating considerations of climate change and development, a perspective that is certainly needed. More generally, the IPCC suffers because it no longer considers “policy options” under its mandate. Since its First Assessment Report when it did consider policy options, the IPCC has eschewed responsibility for developing and evaluating a wide range of possible policy options on climate change. By deciding to policy outside of its mandate since 1992, the IPCC, ironically, leaves itself more open to charges of political bias. It is time for the IPCC to bring policy back in, both because we need new and innovative options on climate, but also because the IPCC has great potential to serve as an honest broker. But until it does, its leadership would be well served to avoid either the perception or the reality of endorsing particular political perspectives.

    Consider the following imaginary scenario. NGOs and a few other representatives of the oil and gas industry decide to band together to produce a report on what they see as needed and unnecessary policy actions related to climate change. They put together a nice glossy report with findings and recommendations such as: *Coal is the fuel of the future, we must mine more. *CO2 regulations are too costly. *Climate change will be good for agriculture. In addition, the report contains some questionable scientific statements and associations. Imagine further that the report contains a preface authored by a prominent scientist who though unpaid for his work lends his name and credibility to the report. How might that scientist be viewed by the larger community? Answers that come to mind include: "A tool of industry," "Discredited," "Biased," "Political Advocate." It is likely that in such a scenario that connection of the scientist to the political advocacy efforts of the oil and gas industry would provide considerable grist for opponents of the oil and gas industry, and specifically a basis for highlighting the appearance or reality of a compromised position of the scientist. Fair enough?

Privacy Network Security

  • Popular Science explains the rationale: China and other regimes around the world inherently have an upper hand when it comes to cyber defense because their lack of civil liberty protections lets the government freely monitor online activity. Things like “deep packet inspection” (which gained notoriety during Iranian election protests back in 2009) that let governments monitor citizens traffic also let them monitor for unusual activity … The U.S. Internet, by virtue of its adherence civil liberties, is more like the wild west. Everyone does everything online anonymously, and while that’s great for liberties, it’s also dangerous when cyber criminals/foreign hackers are roaming the cyber countryside
  • The .secure zone would essentially mimic the way the internet is regulated in more oppressive regimes, creating a space where banks, government contractors and the government can do business without fear of being hacked. Keith Alexander, who has the totally not made-up title of Cyber Command Chief, and several lawmakers are pushing for the new infrastructure, saying it’s absolutely necessary for national security. While the vulnerability of our infrastructure is a major concern, we’d wager a lot of Americans might have a problem with a section of the internet where your right to privacy is nonexistent.

    How do you stop hackers from attacking your network? Build an entirely new infrastructure. That's the idea behind the new .secure network, which will work just like any other network except for one thing: once you enter, you waive your right to privacy.

Neuroscience Morality Behavior Free Will Rationality Facts Data Bioethics

    Over the past decade, an army of psychologists, neuroscientists, and evolutionary biologists has been busy trying to uncover the neural "clockwork" that underlies human morality. They have started to trace the evolutionary origins of pro-social sentiments such as empathy, and have begun to uncover the genes that dispose some individuals to senseless violence and others to acts of altruism, and the pathways in our brain that shape our ethical decisions. And to understand how something works is also to begin to see ways to modify and even control it. Indeed, scientists have not only identified some of the brain pathways that shape our ethical decisions, but also chemical substances that modulate this neural activity.
