Moral hazard invades the scientific sphere

Filed under: Economics, Government, Media, Science — Tags: , , — Nicholas @ 12:23

Bill Frezza looks at an unanticipated consequence of pouring more government money into the sciences:

Science and the scientific method are the jewels in the crown of Western civilization. The ascertainment of facts, construction of reproducible experiments, development of falsifiable theories, impartial training and meritocratic advancement of practitioners, and — most importantly — integrity of the publication process by which a well established body of truth can be confidently assembled all underpin the respect accorded to science by the citizenry. In modern times, this respect translates into tax dollars.

Unfortunately, today those tax dollars are corrupting the process. Unprecedented billions are doled out by unaccountable federal and state bureaucracies run by and for the benefit of a closed guild of practitioners. This has created a moral hazard to scientific integrity no less threatening than the moral hazard to financial integrity that recently destroyed our banking system.

According to a report in Nature Reviews Drug Discovery, nearly two-thirds of the experimental results published in peer-reviewed journals could not be reproduced in Bayer’s labs. The latest special issue of Science is devoted to the growing problem of irreproducibility. The Wall Street Journal reports that Amgen, Pfizer, and others have abandoned research programs after spending hundreds of millions pursuing academic research that could never be replicated.

Steve Jones: The problem with belief

Filed under: Britain, Education, Religion, Science — Tags: , , , — Nicholas @ 11:06

In the Telegraph, Steve Jones talks about the growing problem that many British students have when the science conflicts with their religious beliefs:

I have tried asking students at quite what point they find my lectures unacceptable: is it the laws of inheritance, mutation, the genes that protect against malaria or cancer, the global shifts in human skin colour, Neanderthal DNA, or the inherited differences between apes and men? Each point is, they say, very interesting — but when I point out that they have just accepted the whole truth of Darwin’s theory they deny that frightful thought. Some take instant umbrage, although a few, thank goodness, do leave the room with a pensive look.

The problem is not with any particular belief system but with belief itself. Sir Francis Bacon once said that: “If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.” In other words, if you are absolutely sure that you are right whatever the evidence, you will end up in trouble; but if you are always willing to change your mind when the facts change you will emerge with a robust view of how the world works.

I sometimes wonder how many of those who pour their inane opinions about creationism into their young pupils’ ears ever consider the damage they are doing; not to my science, but to their religion. Why, when a student begins to learn the simple and convincing facts, rather than the fantasies, about how life emerged, should he believe anything else that his pastor, his rabbi or his imam has told him? Why build a philosophy based on fixed untruths, when we have so many truths, and so many things still to find out?

It’s one thing to be unhappy when the facts change, and quite another to refuse the facts because they conflict with your beliefs.

Charles Stross on worldbuilding for SF stories

Filed under: Books, Economics, History, Media, Science, Technology — Tags: , , , — Nicholas @ 09:46

This is the sort of thing that more science fiction authors should take into account before they write, but not enough seem to do:

So here are some rules of thumb I use, tending towards an increasingly narrow focus. (Sorry if you were expecting me to address the broader uses of confabulation as a fictional tool; this is very much a set of practical guidelines rather than an examination of the theory behind the activity.)

1. Humans are interested in reading fiction about humans.

Constraint #1 on any work of fiction is that it needs to provide an environment in which recognizable human protagonists can exist. If they’re not human (e.g. “Diaspora”, by Greg Egan; “Saturn’s Children”, by me) you need to provide some sort of continuity with the human and give the reader reasons to feel concerned for them. Or you can go for the “they’re not human, don’t look human, and they have no connection with us”, but what you get is either borderline-unreadable at best, or suffers from human-mind-in-a-giant-land-snail-body syndrome (which risks demolishing the reader’s willing suspension of disbelief).

So I’m going to focus on providing a human environment …

2. In general, High Fantasy steals its dress from pre-modern history; Urban Fantasy buys off-the-shelf in TK-Maxx: and Science Fiction goes for that bold futurist look.

Which is to say, if you’re going to write a trilogy with a young soldier on the rise and a throne and an evil emperor, you can do a lot worse than plunder the decline and fall of the Roman Empire for your social background. Note, however, that you’ll do a lot better if you read some social history texts rather than believing what you see in the movies.

That last bit is especially good advice, as the more you know about cultures other than the one you were raised in, the better you can understand why things are different. Ancient Babylonians were not just Englishmen with funny clothes. Classic Greece, for all that it provided a lot of the underpinnings of our western culture, was functionally very different from life as we know it now.

“[Fill-in-the-blank] is now a clear and present danger”

Filed under: Environment, Health, Media, Science — Tags: , , , , — Nicholas @ 12:07

Andrew Orlowski explains how we keep falling for junk science through media exposure:

Firstly. An obscure researcher or scientist will make a dramatic claim.

The media picks up on this, and a reporter is assigned to the story. The reporter will have no scientific background — but looks to the state and the bureaucracy to do something. Anything.

The hapless minister is then hauled on to explain the inaction. He will be intelligent — he is likely to have a PPE from Oxford, like the presenter — but no specialist knowledge. He, too, trusts the scientists.

A pledge is then made to increase funding for the scientist who makes the claim.

A pledge is also made to act — by introducing legislation or other regulations. Perhaps a task force or committee will also be involved:

Climategate 2.0 for dummies

Filed under: Environment, Media, Politics — Tags: , , , — Nicholas @ 08:34

For anyone who managed to avoid hearing about the original release of emails from many of the leading lights in the anthropogenic global warming community, revealing a much more sordid and less-than-honest process to publicize information on the global climate, James Delingpole explains why the latest batch of emails are important:

The latest batch of emails, leaked by a person or persons unknown (but whoever they are they deserve a Congressional Medal of Honor at the very least) comprises 5,000 files, dumped as before onto a Russian server, revealing private correspondence between many of the scientists at the heart of the Great Global Warming scam.

These are men like Penn State’s increasingly infamous Michael Mann (inventor of the discredited Hockey Stick) and the University of East Angia’s Phil Jones: not just two-bit research assistants but the “experts” whose data, research papers and lobbying forms the basis of the Intergovernmental Panel on Climate Change’s (IPCC) pronouncements on Anthropogenic Global Warming.

The IPCC, in turn, is the organization on whose doomy prognostications of man-made climate disaster our political leaders base their policy. So when Obama pours billions of your tax dollars into failed clean-tech companies like Solyndra, when you are banned from using the kind of lightbulbs that actually illuminate a room rather than merely flicker and give you a headache, when the EPA’s Lisa Jackson tries reducing the number of showers you take or seeks to regulate when you use your aircon, when your energy bills rise and your flights grow more expensive due to carbon taxes — all these infringements on your economic wellbeing and your liberty can be traced back to these Climategate scientists. This is why Climategate matters.

The shot that started the First Interplanetary War?

Filed under: Space — Tags: — Nicholas @ 08:25

Yes, it may not happen for a few more decades, but we were the instigators of what might be the most long-distance war in human history:

The new habitability study has involved the collaborating scientists devising two different indexes for rating worlds, in proper scientifiction style*. We now have the Earth Similarity Index (ESI), showing how much like Earth a body is, on which Earth is 1, Mars is 0.7 and our Moon is 0.56.

The scientists have also worked out a Planet Habitability Index (PHI), based on such things as planetary magnetic fields, atmosphere, likely local temperatures etc. Titan, icy natural-gas slush moon of Saturn, scores high on this at 0.64.

But, very worryingly, the planets of the dim, red M-class star Gliese 581 — lying just 20 light-years away in the constellation Libra — score high up the listings in both systems. Under ESI, the exoplanets Gliese 581g, d and c are the next three most habitable known worlds after Earth: and they are also well up under PHI.

Normally this would not be cause for alarm, but — as regular readers of Reg exoplanet coverage will know — should there be intelligent aliens at Gliese 581 they will soon have an intense and well-justified grievance against us.

It was a deliberate and evil provocation we gave, and our fate may already be sealed.

The biggest threat to the environmental movement

Filed under: Economics, Science, Technology — Tags: , , — Nicholas @ 09:50

No, it’s not some ferociously polluting corporation, or a dangerously powerful conservative politician or a candidate for the GOP nomination in the United States. It’s algae:

“We can engineer, humbly, like we have been domesticating plants for a long time,” one scientist told me. “We engineer the algae to do biochemically something quite different to what they’d be doing in the wild: they still take photons from the sun, and via biology, turn it into a useful captured molecule. We have them doing something similar but with stunning efficiency: it’s 40 to 100 times more efficient,” says Elbert Branscomb, chief scientist to the US Department of Energy.

There are (at least) around 60 startups hoping to produce oil and diesel biologically, with accelerated fermentation or photosynthesis techniques to produce an end product that is 100 per cent compatible with the existing infrastructure. Some, for example, tweak the algae to make them do photosynthesis anything from 40 to 100 times more efficiently. LS9 received $30m in funding and has a one-step process to convert sugar to create renewable petrol. It expects production within five years. If oil prices remain high, say over $40 or $50 a barrel, then it’s viable.

So why is this the biggest threat to the environmental movement?

But the greatest challenge cheap hydrocarbons poses is for people whose outlook is founded on what I call “End Times logic”. The most successful political movement in recent years is environmentalism, which expanded from specific concerns about pollution and conservation into an all-encompassing worldview, complete with very preachy appeals to changing parts of our lifestyles.

These ranged from “Don’t flush the loo too often”, to “Don’t fly for a weekend break”, to “Eat less red meat”. Very few politicians have felt courageous enough to contradict this. And the movement has achieved its ascendancy through urgent, apocalyptic appeals, rather than using calmer methods of rational persuasion which involve costs and benefits to be totted up. These new energy sources pose a profound problem: they saves the planet, and we carry on with minimum disruption.

I expect that one effect will be that environmentalism will become much more about everyday concerns such as pollution, and conservations again, back to where it started. But it grew into a vacuum, after the end of the Cold War, when great political ideas seemed to lose credibility. As a way of driving the political agenda, it will become currency without value. Buzzwords such as “sustainability”, founded on a resource-constrained view, will no longer be credible. People will simply laugh at them.

EU panel spends three years to determine that water cannot be sold as a remedy for dehydration

Filed under: Bureaucracy, Europe, Health — Tags: , — Nicholas @ 08:53

Ah, Brussels! What would we do without you and your panels of experts on quiet news days?

Brussels prompted a flood of abuse this week by apparently banning bottled water vendors from promoting their products as a counter to dehydration.

The European Food Standards Agency was asked to consider its “opinion on the scientific substantiation of a health claim related to water and reduced risk of development of dehydration and of concomitant decrease of performance”.

The request for clarification was submitted by two German professors in 2008, in a bid to determine what health claims could be slapped on bottled water. A panel deliberated on the issue for three years, before the adjudication was delivered back in February, in time to hit the UK’s Euro-sceptical media yesterday.

QotD: The uses of junk science

Filed under: Environment, Health, Media, Quotations — Tags: — Nicholas @ 00:05

The Sierra Club campaign against coal is motivated by a desire to reduce CO2 emissions to prevent global warming. But since global warming skepticism and global warming fatigue are widespread, the club has opted for a junk science approach to reach its goals. The club tells people that their babies will die, or at least get asthma, if coal plants continue to operate. Although the cause of asthma is not known, it is suspected that it is related to the high levels of cleanliness in advanced countries that denies children and their immune systems exposure to the dirt and filth found in primitive places. This is known as the hygiene hypothesis. The incidence of asthma is about 50 times higher in developed countries compared to rural Africa. For all the Sierra Club knows, coal plants may prevent asthma. Given the hygiene hypothesis, that seems plausible.

With junk science, it is easy to scare people. There are many things that are bad for us that are present at low levels in the environment — for example, mercury, lead, radiation, or tobacco smoke. The junk science approach to trace toxins is to claim that if a high level of the bad thing would cause X people to get sick, then a level 10,000 times smaller must cause 1/10,000 as many people to get sick. Given 300 million people in the country, this math can give you thousands of people getting sick from low levels of mercury, lead, radiation, or secondhand tobacco smoke. This approach is known as the linear no threshold hypothesis.

The Sierra Club and its ally, the Environmental Protection Agency, lean on the small emissions of mercury from burning coal to work up a calculation of deaths from coal. They minimize the fact that much of the mercury falling on the U.S. comes from China, volcanoes, or even from burning dead bodies with mercury-based fillings in their teeth. Mercury pollution becomes an excuse to get rid of coal. Arguing the science behind such claims often degenerates into a paper chase about statistics and what studies are good or bad. From the bureaucratic point of view, the linear no threshold hypothesis is wonderful because it means that problems are never solved and there is always a need for more bureaucratic activity.

“It is a sad state of affairs when an amazing feat of engineering is only seen in bleak environmental and misanthropic terms”

Filed under: Americas, Economics, Environment, Pacific — Tags: , — Nicholas @ 09:16

Nick Thorne wonders why the soon-to-be-completed road link between Peru and Brazil, the Interoceánica, has gotten such poor press in the west:

In July this year, an amazing feat of engineering and testament to the progress of Latin America went almost completely unreported in the Western media. With the opening of the Puente Billingshurst, a half-mile suspension bridge across the Madre Dios river, the interoceanic highway or Interoceánica neared completion. Soon, a long-held dream will finally come true: for the first time, a road will stretch all the way from the Pacific to the Atlantic, crossing the whole of South America.

The road starts in the Peruvian capital, Lima. It crosses the Andes, reaching a highest point of 4,850 metres (higher than Mont Blanc), then plunges into the rainforest, crosses several tributaries of the mighty Amazon, and after a total of 3,400 miles it reaches the Atlantic coast of Brazil. Much of the route has been in place for decades, but a 460-mile middle section was still missing. With the opening of the bridge, the road’s completion is in sight.

Comparisons have rightly been made between the Interoceánica and the first North American transcontinental railroad completed in 1869. In Brazil, the highway has already been dubbed ‘the road to China’. In 2009, China overtook the US as Brazil’s largest trading partner. Chinese trade will be able to use the Peruvian ports on the Pacific coast, cutting out a long detour via Cape Horn or the Panama Canal. While Brazil will be the main beneficiary, Peru will benefit as a middle-man. The think tank Bank Information Centre estimates that the highway will lead to a 1.5 per cent annual increase in GDP in Peru. The highway will facilitate greater regional integration and is a real symbol of Latin America’s economic awakening. A triumphant banner along the highway reads ‘once a promise, now a reality’. In 2006, a mere 3,500 people crossed the border from Peru to Brazil. By 2009, with the partial completion of the highway, this had already increased ten-fold to 35,000.

The “shale gale” blows away Canada’s illusions of being an “energy superpower”

Filed under: Cancon, Economics, Environment, USA — Tags: , , , — Nicholas @ 12:50

Terence Corcoran pours cold water on the notion that this is the moment for Canada to become a major player in the world energy markets:

In recent weeks, Canada — a self-proclaimed global energy superpower — has been trying to throw its weight around over the Keystone XL pipeline, TransCanada Corp.’s $7-billion project to ship oil sands production from Alberta to Texas. In Houston on Tuesday, Natural Resources Minister Joe Oliver let the Americans know that Canada had other options. “What will happen if there wasn’t approval [of Keystone] — and we think there will be — is that we’ll simply have to intensify our efforts to sell the oil elsewhere.”

Canadian oil executives, who have a lot invested in the superpower notion, are also issuing aggressive-sounding statements aimed at the United States. A headline in The Globe and Mail Friday sounded like a threat: “Oil patch to U.S.: OK pipe or lose our oil.” The story didn’t quite back up the headline, but the sense was that Canada was developing alternatives and that China is the big alternative.

[. . .]

While Canadian government and industry officials have a lot invested in the idea of energy superpowerdom, few outside observers share the vision. Canada barely rates a mention in The Quest: Energy, Security and the Remaking of the Modern World, Daniel Yergin’s new book on the world energy market. A few pages are devoted to the oil sands, mostly to review the high costs and technical difficulties. “As the industry grows in scale, it will require wider collaboration on the R&D challenges, not only among oil companies and the province of Alberta, but also with Canada’s federal government.”

Far more impressive for the world’s energy future will be the impact of shale gas and shale oil. The “shale gale,” as Mr. Yergin calls it, has already transformed the U.S. gas market and shale oil could be next. Since Mr. Yergin’s book was written, the shale revolution has swept Europe and is about to transform China’s energy market.

A “fat tax” would not improve anyone’s health or the healthcare sector

Filed under: Government, Health, Liberty, Media — Tags: , , , — Nicholas @ 09:10

Politicians and “food celebrities” in many western countries are calling for a tax on obesity, either on the foods that “make people fat” or on obese people themselves. Other than being incredibly regressive (poor people in the west tend to be fatter than well-off people), such a tax would do nothing to address the problem it is supposed to solve:

The regular calls for a fat tax — whether on the ‘wrong’ foods or on fat people themselves — are symptomatic of two regressive trends in society. The first is the view that experts know best, that these latter-day sages can come to an impartial view based on The Science, then guide government about the appropriate policy action. The new, evidence-based policy usually involves some kind of manipulation of our individual behaviour from gentle ‘nudges’ and increasing taxes through to criminalisation, as in the case of the smoking ban.

But this is not evidence-based policy, but policy-based evidence, with preconceived ideas being pushed through in the name of science at a time when those at the top of society have lost the ability to convince the electorate on the basis of a moral or political argument. This style of policymaking rarely solves social problems, but it does distort both politics and science.

The second worrying trend is the sheer intolerance towards obese people. Being very overweight has always attracted a certain amount of moral opprobrium. But Hatton’s outlook reflects a sea-change. Once, the NHS reflected a progressive outlook that disease was a misfortune that could strike any of us at any time and that the best thing to do was to share that burden across society. Now it’s every man and woman for themselves. In the worldview of Hatton and Coren, some morally weak individuals are costing them money and must be punished.

Ironically, this flows from a left-wing view of disease as having social causes. In the late Seventies, left-wingers correctly saw that some ill-health was the result of poverty, poor housing, polluted air, and so on rather than infection or bad luck. Unfortunately, this has morphed into the idea that disease is caused by individual behaviour — and so health professionals have taken to camping out in our private lives, demanding we stop smoking, drinking and eating the wrong things. Every naughty little pleasure must now be sacrificed to the god of longevity. If we don’t play ball, this intolerance suggests we should lose our right to treatment.

The disease of intolerance is likely to have a far more detrimental effect on society than obesity ever could.

QotD: Economics is not a “hard science”

Filed under: Economics, Quotations, Science — Tags: , , , — Nicholas @ 13:20

The problem at base is that economics is not a branch of mathematics or statistics, no matter how much economists wish it was. Never forget that the economics equations you see, the pretty graphs and charts, are just educated guesses that are wrong more often than not — economists love the gloss of the hard sciences, but the truth is that the field is firmly placed among the philosophical and sociological disciplines. Economics is a study of human behavior more than anything else, with all the uncertainties and confusion that entails.

China’s increased output of scientific papers masks deeper problems

Filed under: China, Media, Science — Tags: , , , — Nicholas @ 12:01

Colby Cosh linked to an interesting press release from the Chinese Academy of Sciences, which shows a surge in published papers from China, but a significant drop in the rate at which those papers are cited:

Chinese researchers published more than 1.2 million papers from 2006 to 2010 — second only to the United States but well ahead of Britain, Germany and Japan, according to data recently published by Elsevier, a leading international scientific publisher and data provider. This figure represents a 14 percent increase over the period from 2005 to 2009.

The number of published academic papers in science and technology is often seen as a gauge of national scientific prowess.

But these impressive numbers mask an uncomfortable fact: most of these papers are of low quality or have little impact. Citation per article (CPA) measures the quality and impact of papers. China’s CPA is 1.47, the lowest figure among the top 20 publishing countries, according to Elsevier’s Scopus citation database.

China’s CPA dropped from 1.72 for the period from 2005 to 2009, and is now below emerging countries such as India and Brazil. Among papers lead-authored by Chinese researchers, most citations were by domestic peers and, in many cases, were self-citations.

Being published is very important for sharing discoveries and advancing the careers of the scientists, but it’s more important that those publications be read and referenced by other scientists. Self-citations are akin to self-published works: it doesn’t guarantee that the work is useless, but it increases the chances that it is.

Perhaps worse than merely useless publication is the culture of corruption that has grown up around the scientific community:

In China, the avid pursuit of publishing sometimes gives rise to scientific fraud. In the most high-profile case in recent years, two lecturers from central China’s Jinggangshan University were sacked in 2010 after a journal that published their work admitted 70 papers they wrote over two years had been falsified.

[. . .]

A study done by researchers at Wuhan University in 2010 says more than 100 million U.S. dollars changes hands in China every year for ghost-written academic papers. The market in buying and selling scientific papers has grown five-fold in the past three years.

The study says Chinese academics and students often buy and sell scientific papers to swell publication lists and many of the purported authors never write the papers they sign. Some master’s or doctoral students are making a living by churning out papers for others. Others mass-produce scientific papers in order to get monetary rewards from their institutions.
