Many of the smartphones, laptops, cameras and other gizmos Americans rely on every day contain metals from the Congo, where profits from these "blood" minerals pay for guns, bullets and other weapons.

Western consumers have no clue about the true costs of their gadget addition, but the people behind the Enough campaign hope to change that and push electronics companies, with help from a new web video, to do more to fight against conflict minerals

n a video spoofing Apple's famous "I'm a Mac, and I'm a PC" ads, Enough explains some of the problems caused by the minerals tantalum, tungsten and tin. The spot's sad punchline claims that Macs and PCs have at least one thing in common -- they both contain those "three T" conflict metals.

Last year the InterAcademy Council recommended that The IPCC should develop and adopt a rigorous conflict of interest policy that applies to all individuals directly involved in the preparation of IPCC reports

  Now we get treated to sights like the following: . . . Steve Sawyer, who contributed a chapter to an upcoming Intergovernmental Panel on Climate Change (IPCC) special report on managing climate disasters, which will be published in May. . . According to Sawyer, the forthcoming IPCC report will reveal that carbon emissions from nuclear power facilities clock up between 100 and 200 grams of carbon emissions per kilowatt hour (kWh). 'Clean' gas emits around 350 grams of carbon per kilowatt hour.    But wind turbines emit no carbon when producing electricity. One life-cycle assessment of the Vestas V90-3.0MW onshore turbine – which includes the manufacture of components – found that even here, only 4.64 grams of CO2 per kWh were created. "Nuclear power is generally the most expensive, complicated and dangerous means ever devised by human beings to boil water," Sawyer said, summing up the anti-nuclear argument. "Why anyone would want to use it to generate electricity is beyond me, unless they were interested - as most European states were in the early days of nuclear history - in what comes out the other end, which is fissionable material for nuclear weapons," he added.Who is this IPCC author Steve Sawyer you might wonder?  He is the Secretary General of the Global Wind Energy Council, an advocacy group for wind energy with a strong anti-nuclear stance, as Sawyer's comments indicate. He also spent 30 years as a top official for Greenpeace.

the spectacle of an IPCC author with a clear conflict of interest writing part of the report and then using that same report in his political advocacy just does not look good. If the IPCC were recommending drug safety standards and an author happened to be a top official at a company benefitting from the recommendations, the issues here would be obvious and unacceptable. The IPCC however plays by different rules.

The first major test of these changes will be towards the end of this year, with the release of a report assessing whether climate change is increasing the likelihood of extreme weather events. Despite much speculation, there is scant scientific evidence for such a link — particularly between climate warming, storm frequency and economic losses — and the report is expected to spark renewed controversy. "It'll be interesting to see how the IPCC will handle this hot potato where stakes are high but solid peer-reviewed results are few," says Silke Beck, a policy expert at the Helmholtz Centre for Environmental Research in Leipzig, Germany.

Some 1500 documents revealed in litigation provide unprecedented insights into how pharmaceutical companies promote drugs, including the use of vendors to produce ghostwritten manuscripts and place them into medical journals.

Dozens of ghostwritten reviews and commentaries published in medical journals and supplements were used to promote unproven benefits and downplay harms of menopausal hormone therapy (HT), and to cast raloxifene and other competing therapies in a negative light.

the pharmaceutical company Wyeth used ghostwritten articles to mitigate the perceived risks of breast cancer associated with HT, to defend the unsupported cardiovascular “benefits” of HT, and to promote off-label, unproven uses of HT such as the prevention of dementia, Parkinson's disease, vision problems, and wrinkles.

In his fascinating new book, "Some We Love, Some We Hate, Some We Eat," Hal Herzog looks at the wild, tortured paradoxes in our relationship with the weaker, if sometimes more adorable, species.

it's the human-meat relationship. The fact is, very few people are vegetarians; even most vegetarians eat meat. There have been several studies, including a very large one by the Department of Agriculture, where they asked people one day: Describe your diet. And 5 percent said they were vegetarians. Well, then they called the same people back a couple of days later and asked them about what they ate in the last 24 hours. And over 60 percent of these vegetarians had eaten meat. And so, the fact is, the campaign for moralized meat has been a failure. We actually kill three times as many animals for their flesh as we did when Peter Singer wrote "Animal Liberation" [in 1975]. We eat probably 20 percent more meat than we did when he wrote that book. Even though people are more concerned about animals, it seems like that's been occurring. The question is, why?

Should doctors, pharmacists and other health care workers have the right to refuse to provide services that conflict with their religious beliefs?

n March 2009, Julea Ward, a student at Eastern Michigan University (EMU), was dismissed from her graduate-level counseling program when she refused to counsel a gay man about a same-sex relationship.

The supervisor claimed that Ms. Ward's refusal violated the ethical obligations of a counselor not to discriminate against clients based on sexual orientation or to impose one's personal beliefs on clients. Based on this judgment, the school expelled Ms. Ward from the counseling program.

conflict minerals are helping fuel the deadliest war in the world since World War II, the conflict in eastern Congo in which 1,100 women are raped every month, and 1,500 people die every day. The main armed groups that orchestrate the violence make hundreds of millions of dollars by trading in four minerals - the 3 Ts of tin, tantalum, tungsten, and gold. These minerals are then bought by electronics and jewelry companies and are used in our cell phones, laptops, and gold necklaces.

Scientists these days tend to keep up a polite fiction that all science is equal. Except for the work of the misguided opponent whose arguments we happen to be refuting at the time, we speak as though every scientist's field and methods of study are as good as every other scientist's and perhaps a little better. This keeps us all cordial when it comes to recommending each other for government grants.

Why should there be such rapid advances in some fields and not in others? I think the usual explanations that we tend to think of - such as the tractability of the subject, or the quality or education of the men drawn into it, or the size of research contracts - are important but inadequate. I have begun to believe that the primary factor in scientific advance is an intellectual one. These rapidly moving fields are fields where a particular method of doing scientific research is systematically used and taught, an accumulative method of inductive inference that is so effective that I think it should be given the name of "strong inference." I believe it is important to examine this method, its use and history and rationale, and to see whether other groups and individuals might learn to adopt it profitably in their own scientific and intellectual work. In its separate elements, strong inference is just the simple and old-fashioned method of inductive inference that goes back to Francis Bacon. The steps are familiar to every college student and are practiced, off and on, by every scientist. The difference comes in their systematic application. Strong inference consists of applying the following steps to every problem in science, formally and explicitly and regularly: Devising alternative hypotheses; Devising a crucial experiment (or several of them), with alternative possible outcomes, each of which will, as nearly is possible, exclude one or more of the hypotheses; Carrying out the experiment so as to get a clean result; Recycling the procedure, making subhypotheses or sequential hypotheses to refine the possibilities that remain, and so on.

On any new problem, of course, inductive inference is not as simple and certain as deduction, because it involves reaching out into the unknown. Steps 1 and 2 require intellectual inventions, which must be cleverly chosen so that hypothesis, experiment, outcome, and exclusion will be related in a rigorous syllogism; and the question of how to generate such inventions is one which has been extensively discussed elsewhere (2, 3). What the formal schema reminds us to do is to try to make these inventions, to take the next step, to proceed to the next fork, without dawdling or getting tied up in irrelevancies.

the 2011 Edelman Trust Barometer, published by research firm StrategyOne, which surveyed 5,075 "informed publics" in 23 countries on their trust in business, government, institutions and individuals. One of the questions asked of respondents was: "If you heard information about a company from one of these people, how credible would that information be?". Of the eight groups of individuals - academic/expert, technical expert in company, financial/industry analyst, CEO, non-governmental organisation representative, government official, person like myself, and regular employee - academic/expert came out tops with a score of 70 per cent, followed by technical expert at 64 per cent.

the film on the global financial crisis Inside Job, which won the 2011 Academy Award for best documentary. One of the documentary's themes is the role a number of renowned academics, particularly academic economists, played in the global crisis. It highlighted potentially serious conflicts of interests related to significant compensation derived by these academics serving on boards of financial services firms and advising such firms.

Often, these academics also played key roles in shaping government policies relating to deregulation - most appear allergic to regulation of the financial services industry. The documentary argued that these academics from Ivy League universities had basically become advocates for financial services firms, which blinded them to firms' excesses. It noted that few academic economists saw the financial crisis coming, and suggested this might be because they were too busy making money from the industry.

Citizens of a functioning democracy must be able to know what the state is saying and doing in our name, to engage in what Pierre Rosanvallon calls “counter-democracy”*, the democracy of citizens distrusting rather than legitimizing the actions of the state. Wikileaks plainly improves those abilities.

On the other hand, human systems can’t stand pure transparency. For negotiation to work, people’s stated positions have to change, but change is seen, almost universally, as weakness. People trying to come to consensus must be able to privately voice opinions they would publicly abjure, and may later abandon. Wikileaks plainly damages those abilities. (If Aaron Bady’s analysis is correct, it is the damage and not the oversight that Wikileaks is designed to create.*)

we have a tension between two requirements for democratic statecraft, one that can’t be resolved, but can be brought to an acceptable equilibrium. Indeed, like the virtues of equality vs. liberty, or popular will vs. fundamental rights, it has to be brought into such an equilibrium for democratic statecraft not to be wrecked either by too much secrecy or too much transparency.

Prinz’s basic stance is that moral values stem from our cognitive hardware, upbringing, and social environment. These equip us with deep-seated moral emotions, but these emotions express themselves in a contingent way due to cultural circumstances. And while reason can help, it has limited influence, and can only reshape our ethics up to a point, it cannot settle major differences between different value systems. Therefore, it is difficult, if not impossible, to construct an objective morality that transcends emotions and circumstance.

As Prinz writes, in part:“No amount of reasoning can engender a moral value, because all values are, at bottom, emotional attitudes. … Reason cannot tell us which facts are morally good. Reason is evaluatively neutral. At best, reason can tell us which of our values are inconsistent, and which actions will lead to fulfillment of our goals. But, given an inconsistency, reason cannot tell us which of our conflicting values to drop or which goals to follow. If my goals come into conflict with your goals, reason tells me that I must either thwart your goals, or give up caring about mine; but reason cannot tell me to favor one choice over the other. … Moral judgments are based on emotions, and reasoning normally contributes only by helping us extrapolate from our basic values to novel cases. Reasoning can also lead us to discover that our basic values are culturally inculcated, and that might impel us to search for alternative values, but reason alone cannot tell us which values to adopt, nor can it instill new values.”

This moral relativism is not the absolute moral relativism of, supposedly, bands of liberal intellectuals, or of postmodernist philosophers. It presents a more serious challenge to those who argue there can be objective morality. To be sure, there is much Prinz and I agree on. At the least, we agree that morality is largely constructed by our cognition, upbringing, and social environment; and that reason has the power synthesize and clarify our worldviews, and help us plan for and react to life’s situations

It is both misguided and dangerous to push unobserved risks further into the statistical tails of the probability distribution of outcomes and allow these high-impact, low-probability "tail risks" to disappear from policymakers' fields of observation.

Such environments eventually experience massive blowups, catching everyone off-guard and undoing years of stability or, in some cases, ending up far worse than they were in their initial volatile state. Indeed, the longer it takes for the blowup to occur, the worse the resulting harm in both economic and political systems.

Seeking to restrict variability seems to be good policy (who does not prefer stability to chaos?), so it is with very good intentions that policymakers unwittingly increase the risk of major blowups. And it is the same misperception of the properties of natural systems that led to both the economic crisis of 2007-8 and the current turmoil in the Arab world. The policy implications are identical: to make systems robust, all risks must be visible and out in the open -- fluctuat nec mergitur (it fluctuates but does not sink) goes the Latin saying.

The USPSTF recently issued an even sharper warning about the prostate-specific antigen test for prostate cancer, after concluding that the test’s harms outweigh its benefits. Chest X-rays for lung cancer and Pap tests for cervical cancer have received similar, albeit less definitive, criticism.CommentsView/Create comment on this paragraphThe next step in the reevaluation of cancer screening was taken last year, when researchers at the Dartmouth Institute for Health Policy announced that the costs of screening for breast cancer were often minimized, and that the benefits were much exaggerated. Indeed, even a mammogram (almost 40 million are given annually in the US) that detects a cancer does not necessarily save a life.CommentsView/Create comment on this paragraphThe Dartmouth researchers found that, of the estimated 138,000 breast cancers detected annually in the US, the test did not help 120,000-134,000 of the afflicted women. The cancers either were growing so slowly that they did not pose a problem, or they would have been treated successfully if discovered clinically later (or they were so aggressive that little could be done).

the conversation should include scientists from academia and government; we also think it should include scientists from industry. Because industry is increasingly the interface between science and society.

The bloggers who blog on 'corporate blogs' on SB are necessarily credentialed scientists (we make sure of that), in some cases highly credentialed scientists who have published extensively in peer-reviewed journals. The fact that they work at a profit-making company does not automatically disqualify their science in our mind. And frankly, nor does it disqualify them in the eyes of the Nobel Prize Committee either.

Literature teaches us about life. Literature helps us understand the world.

this belief in truth-from-fiction is the party line for those who champion the merits of literature. Eminent English professor and critic Harold Bloom proclaims, in his bestselling How to Read and Why, that one of the main reasons to read literature is because "we require knowledge, not just of self and others, but of the way things are."

why would we expect literature to be a reliable source of knowledge about "the way things are"? After all, the narratives which are the most gripping and satisfying to read are not the most representative of how the world actually works. They have dramatic resolutions, foreshadowing, conflict, climax, and surprise. People tend to get their comeuppance after they misbehave. People who pursue their dream passionately tend to succeed. Disaster tends to strike when you least expect it. These narratives are over-represented in literature because they're more gratifying to read; why would we expect to learn from them about "the way things are"?
