Establishments Assume New Methods Are Unsound Methods

(p. 188) For the next two years, Conway coordinated her efforts under Sutherland at PARC with Mead’s ongoing work at Caltech. But she was frustrated with the pace of progress. There was no shortage of innovative design ideas; computerized design tools had advanced dramatically since Mead’s first efforts several years before. Yet the industry as a whole continued in the old rut. As Conway put it later, the problem was “How can you take methods that are new, methods that are not in common use and therefore perhaps considered unsound methods, and turn them into sound methods?” [Conway’s italics].

She saw the challenge in the terms described in Thomas Kuhn’s popular book The Structure of Scientific Revolutions. it was the problem that took Boltzmann to his grave. It was the problem of innovation depicted by economist Joseph Schumpeter in his essays on entrepreneurship: new systems lay waste to the systems of the past. Creativity is a solution for the creator and the new ventures he launches. But it wreaks dissolution–“creative destruction,” in Schumpeter’s words– for the defenders of old methods. In fact, no matter how persuasive the advocates of change, it is very rare that an entrenched establishment will reform its ways. Establishments die or retire or fall in revolution; they only rarely transform themselves.

For 30 Years “Poincaré’s Elegant Math Prevailed Over Boltzmann’s Practical Findings”

(p. 182) . . . , Poincaré’s elegant math prevailed over Boltzrnann’s practical findings. For some thirty years, Boltzmann struggled to get his ideas across. But he failed. He had the word, but he could not find a way to gain its acceptance in the world. For long decades, the establishment held firm.

So in the year 1906, Poincaré became president of the French (p. 183) Académie des Sciences and Boltzmann committed suicide. As Mead debatably puts it, “Boltzmann died because of Poincaré.” At least, as Boltzmann’s friends attest, this pioneer of the modem era killed himself in an apparent fit of despair, deepened by the widespread official resistance to his views.
He died, however, at the very historic moment when all over Europe physicists were preparing to vindicate the Boltzmann vision. He died just before the findings of Max Planck, largely derived from Boltzmann’s probability concepts, finally gained widespread acceptance. He died several months after an obscure twenty-one-year-old student in Geneva named Albert Einstein used his theories in proving the existence of the atom and demonstrating the particle nature of light. In retrospect, Boltzmann can be seen as a near-tragic protagonist in the greatest intellectual drama of the twentieth century: the overthrow of matter.

“If I Listened to Logical People I Would Never Have Succeeded”

We may never know if Gilder’s optimism about Takahashi’s DRAM initiative was prescient or misguided. Takahashi died of pneumonia at age 60 in 1989, the same year that Gilder’s Mircocosm book was published. (Takahashi’s successor abandoned the DRAM initiative.)

(p. 154) Many experts said it could not be done. DRAMs represent the most demanding feat of mass production in all world commerce. None of the complex procedures is easy to automate. Automation itself, moreover, is no final solution to the problems of dust and contamination. Machines collect and shed particles and toxic wastes nearly as much as people do. Chip experts derided the view that these ten-layered and multiply patterned electronic devices, requiring hundreds of process steps, resembled ball bearings in any significant way.

Takahashi knew all that. But experts had derided almost every decision he had made throughout his career. “Successful people,” he says, “surprise the world by doing things that ordinary logical people (p. 155) think are stupid.” The experts told him he could not compete in America with New Hampshire Ball Bearing. He ended up buying it. The experts and bankers had told him not to build his biggest ball-bearing plants in Singapore and Thailand. Those plants are now the world’s most productive. The experts told him not to buy two major facilities in the United States, full of obsolescent equipment and manned by high-priced workers. But those facilities now dominate the American market for precision ball bearings. Now the experts told him he couldn’t make DRAMs. He knew he could. “If I listened to logical people,” he says, “I would never have succeeded.”

Emails Vindicate Skeptics Who Questioned Scientific Basis of Global Warming

(p. A1) Just two years ago, a United Nations panel that synthesizes the work of hundreds of climatologists around the world called the evidence for global warming “unequivocal.”

But as representatives of about 200 nations converge in Copenhagen on Monday to begin talks on a new international climate accord, they do so against a background of renewed attacks on the basic science of climate change.
The debate, set off by the circulation of several thousand files and e-mail messages stolen from one of the world’s foremost climate research institutes, has led some who oppose limits on greenhouse gas emissions, and at least one influential country, Saudi Arabia, to question the scientific basis for the Copenhagen talks.
The uproar has threatened to complicate a multiyear diplomatic effort already ensnared in difficult political, technical and financial disputes that have caused leaders to abandon hopes of hammering out a binding international climate treaty this year.
. . .
(p. A8) On dozens of Web sites and blogs, skeptics and foes of greenhouse gas restrictions take daily aim at the scientific arguments for human-driven climate change. The stolen material was quickly seized upon for the questions it raised about the accessibility of raw data to outsiders and whether some data had been manipulated.
An investigation into the stolen files is being conducted by the University of East Anglia, in England, where the computer breach occurred. Rajendra K. Pachauri, chairman of the United Nations Intergovernmental Panel on Climate Change, has also said he will look into the matter. At the same time, polls in the United States and Britain suggest that the number of people who doubt that global warming is dangerous or caused by humans has grown in recent years.
. . .
Science is about probability, not certainty. And the persisting uncertainties in climate science leave room for argument. What is a realistic estimate of how much temperatures will rise? How severe will the effects be? Are there tipping points beyond which the changes are uncontrollable?
Even climate scientists disagree on many of these questions. But skeptics have been critical of the data assembled to show that warming is occurring and the analytic methods that climate scientists use, including mathematical models used to demonstrate a human cause for warming and project future trends.
Both sides also have at times been criticized for overstatement in characterizing the scientific evidence. The contents of the stolen e-mail messages and documents have given fresh ammunition to the skeptics’ camp.
The Climatic Research Unit’s role as a central aggregator of temperature and other climate data has also made it a target. One widely discussed file extracted from the unit’s computers, presumed to be the log of a researcher named Ian Harris, recorded his years of frustration in trying to make sense of disparate data and described procedures — or “fudge factors,” as he called them — used by scientists to eliminate known sources of error.

(Note: ellipses added.)

Note: the online version of the article includes the following, very interesting, correction of the print version:
Correction: December 15, 2009
Because of an editing error, an article on Dec. 7 about the scientific evidence supporting global warming overstated the level of certainty expressed in a 2007 report by the Intergovernmental Panel on Climate Change, a network of scientists, that human-caused warming was under way and, if unabated, would pose rising risks. The panel said that most warming since 1950 was “very likely” caused by humans, not that there was “no doubt.” The article also misidentified the temperature data cited by a scientist at the University of East Anglia’s Climatic Research Unit who had expressed frustration in a log about trying to make sense of disparate data. The data was direct measurements of temperature, not indirect indicators like the study of tree rings.

Emails Reveal Global Warming Scientists Exclude Contrary Views

One can imagine Michael Crichton looking down on us with a sad smile:

(p. A3) The scientific community is buzzing over thousands of emails and documents — posted on the Internet last week after being hacked from a prominent climate-change research center — that some say raise ethical questions about a group of scientists who contend humans are responsible for global warming.

The correspondence between dozens of climate-change researchers, including many in the U.S., illustrates bitter feelings among those who believe human activities cause global warming toward rivals who argue that the link between humans and climate change remains uncertain.
Some emails also refer to efforts by scientists who believe man is causing global warming to exclude contrary views from important scientific publications.
“This is horrible,” said Pat Michaels, a climate scientist at the Cato Institute in Washington who is mentioned negatively in the emails. “This is what everyone feared. Over the years, it has become increasingly difficult for anyone who does not view global warming as an end-of-the-world issue to publish papers. This isn’t questionable practice, this is unethical.”
John Christy, a scientist at the University of Alabama at Huntsville attacked in the emails for asking that an IPCC report include dissenting viewpoints, said, “It’s disconcerting to realize that legislative actions this nation is preparing to take, and which will cost trillions of dollars, are based upon a view of climate that has not been completely scientifically tested–but rather orchestrated.”
In all, more than 1,000 emails and more than 2,000 other documents were stolen Thursday from the Climate Research Unit at East Anglia University in the U.K. The identity of the hackers isn’t certain, but the files were posted on a Russian file-sharing server late Thursday, and university officials confirmed over the weekend that their computer had been attacked and said the documents appeared to be genuine.
. . .
In one email, Benjamin Santer from the Lawrence Livermore National Laboratory in Livermore, Calif., wrote to the director of the climate-study center that he was “tempted to beat” up Mr. Michaels. Mr. Santer couldn’t be reached for comment Sunday.
In another, Phil Jones, the director of the East Anglia climate center, suggested to climate scientist Michael Mann of Penn State University that skeptics’ research was unwelcome: We “will keep them out somehow — even if we have to redefine what the peer-review literature is!” Neither man could be reached for comment Sunday.

Heretics to the Religion of Global Warming

Source of book image: online version of the WSJ review quoted and cited below.

(p. A19) Suppose for a minute–. . . –that global warming poses an imminent threat to the survival of our species. Suppose, too, that the best solution involves a helium balloon, several miles of garden hose and a harmless stream of sulfur dioxide being pumped into the upper atmosphere, all at a cost of a single F-22 fighter jet.

. . .

The hose-in-the-sky approach to global warming is the brainchild of Intellectual Ventures, a Bellevue, Wash.-based firm founded by former Microsoft Chief Technology Officer Nathan Myhrvold. The basic idea is to engineer effects similar to those of the 1991 mega-eruption of Mt. Pinatubo in the Philippines, which spewed so much sulfuric ash into the stratosphere that it cooled the earth by about one degree Fahrenheit for a couple of years.
Could it work? Mr. Myhrvold and his associates think it might, and they’re a smart bunch. Also smart are University of Chicago economist Steven Levitt and writer Stephen Dubner, whose delightful “SuperFreakonomics”–the sequel to their runaway 2005 bestseller “Freakonomics”–gives Myhrvold and Co. pride of place in their lengthy chapter on global warming. Not surprisingly, global warming fanatics are experiencing a Pinatubo-like eruption of their own.
. . .

. . . , Messrs. Levitt and Dubner show every sign of being careful researchers, going so far as to send chapter drafts to their interviewees for comment prior to publication. Nor are they global warming “deniers,” insofar as they acknowledge that temperatures have risen by 1.3 degrees Fahrenheit over the past century.
But when it comes to the religion of global warming–the First Commandment of which is Thou Shalt Not Call It A Religion–Messrs. Levitt and Dubner are grievous sinners. They point out that belching, flatulent cows are adding more greenhouse gases to the atmosphere than all SUVs combined. They note that sea levels will probably not rise much more than 18 inches by 2100, “less than the twice-daily tidal variation in most coastal locations.” They observe that “not only is carbon plainly not poisonous, but changes in carbon-dioxide levels don’t necessarily mirror human activity.” They quote Mr. Myhrvold as saying that Mr. Gore’s doomsday scenarios “don’t have any basis in physical reality in any reasonable time frame.”
More subversively, they suggest that climatologists, like everyone else, respond to incentives in a way that shapes their conclusions. “The economic reality of research funding, rather than a disinterested and uncoordinated scientific consensus, leads the [climate] models to approximately match one another.” In other words, the herd-of-independent-minds phenomenon happens to scientists too and isn’t the sole province of painters, politicians and news anchors

Fat-Tailed Distributions Seldom Used “Because the Math Was So Unwieldy”

Source of cartoon: online version of the WSJ article quoted and cited below.

(p. C1) Last year, a typical investment portfolio of 60% stocks and 40% bonds lost roughly a fifth of its value. Standard portfolio-construction tools assume that will happen only once every 111 years.

With once-in-a-century floods seemingly occurring every few years, financial-services firms ranging from J.P. Morgan Chase & Co. to MSCI Inc.’s MSCI Barra are concocting new ways to protect investors from such steep losses. The shift comes from increasing recognition that conventional assumptions about market behavior are off the mark, substantially underestimating risk.
. . .
(p. C9) Many of Wall Street’s new tools assume market returns fall along a “fat-tailed” distribution, where, say, last year’s nearly 40% stock-market decline would be more common than previously thought.
Fat-tailed distributions are nothing new. Mathematician Benoit Mandelbrot recognized their relevance to finance in the 1960s. But they were never widely used in portfolio-building tools, partly because the math was so unwieldy.

The Real Disney and the Disney of Academic Critiques

(p. 324) Disney seems no more real in the growing body of academic critiques of the man and the company that bears his name. Many of these critiques are vaguely if not specifically Marxist in their methodology, and they display the usual Marxist tendency to bulldoze the complexities of human behavior in the pursuit of an all–embracing interpretation of Disney’s life and work. What fatally cripples most academic writing about Walt Disney is simple failure to examine its supposed subject. Disney scholarship, like many other kinds of scholarship in today’s academy, feeds on itself. The common tendency is for scholars to rush past the facts of Disney’s life and career, frequently getting a lot of them wrong, in order to write about what really interests them, which is what other scholars have already written. It is this incestuous quality, even more than such commonly cited sins as a reliance on jargon, that makes so much academic writing, on Disney as on other subjects, claustrophobically difficult to read.

Disney has attracted other writers whose unsupportable claims and speculations sometimes win approval of scholars all too eager to believe the worst of the man. The persistent accusations of anti-Semitism are only the mildest examples of an array whose cumulative effect is to portray a Disney who was, among other vile things, racist, misogynist, imperialist, sexually warped. a spy for J. Edgar Hoover, desperate to conceal his illegitimate Spanish birth, (p. 325) and so terrified of death that he had his body cryogenically frozen. Pathologies are undoubtedly at work here, none of them Disney’s.

Walt Disney: “I Don’t Care About Critics”

(p. 286) “He is shy with reporters.” Edith Efron wrote for TV Guide in 1965. “His eyes are dull and preoccupied, his affability mechanical and heavy-handed. He gabs away slowly and randomly in inarticulate, Midwestern speech that would be appropriate to a rural general store. His shirt is open, his tie crooked. One almost expects to see over-all straps on his shoulders and wisps of hay in his hair. . . . If one has the patience to persist, however, tossing questions like yellow flares into the folksy fog, the fog lifts, a remote twinkle appears in the preoccupied eves, and the man emerges.”

Here again, as in other interviews from the 1960s, Disney permitted himself to sound bitter and resentful when he said anything of substance: “These avant-garde artists are adolescents. It’s only a little noisy element that’s going that way, that’s creating this sick art. . . . There is no cynicism in me and there is none allowed in our work. . . . I don’t like snobs. You find some of intelligentsia, they become snobs. They think they’re above everybody else. They’re not. More education doesn’t mean more common sense. These ideas they have about art are crazy. . . . I don’t care about critics. Critics take themselves too seriously. They think the only way to be noticed and to be the smart guy is to pick and find fault with things. It’s the public I’m making pictures for.”

Breakthrough Innovations Require Judgment, Not Surveys

Source of book image: http://press.harvardbusiness.org/on/wp-content/uploads/2009/03/verganti_300dpi.jpg.

(p. W8) In “Design-Driven Innovation” (Harvard Business Press, 272 pages, $35), Roberto Verganti holds that product development should be grounded not in the data of survey-takers or the observations of anthropologists but in the judgment of executives. “We have experienced years of hype about user-centered design,” he says. But breakthrough innovations, in Mr. Verganti’s view, do not represent what customers knew they wanted. Rather, the most profitable innovations are those that create a radically new meaning for a product.

Nintendo’s Wii video-game console and its motion-sensing controllers “transformed what a console meant: from an immersion in a virtual world approachable only by niche experts into an active workout, in the real world, for everyone.” The Swatch in 1983 introduced a new meaning to the watch: neither an article of fine jewelry nor a utilitarian timekeeping tool but a fashion accessory. Starbucks, he says, changed the meaning of a coffee shop from a place to buy coffee to a home away from home.

“A Foolish Faith in Authority Is the Worst Enemy of Truth”

(p. A21) Several years ago I grew concerned about my postmenopausal mother’s risk of osteoporosis. I tried to convince her to initiate hormone replacement therapy. She didn’t listen to me. Instead, she spoke with her gynecologist, who–contrary to best medical evidence at the time–recommended against such treatment. I would eventually be thankful my mother listened to the gynecologist who had known her for decades instead of me and the published medical reviews I was relying on. Some years later my mother was diagnosed with early breast cancer. Had she been on estrogen replacement, it is likely that her tumor would have progressed more rapidly. The gynecologist likely saved my mother’s life.

Studies published in the medical literature are mostly produced by academics who face an imperative to publish or watch their careers perish. These academics aren’t basing their careers on their clinical skills and experiences. Paradoxically, if we allow the academic literature to set guidelines for accepted practices, we are allowing those who are often academics first and clinicians second to determine what clinical care is appropriate.
Consciously or not, those who provide the peer review for medical journals are influenced by whether the work they are reviewing will impact their standing in the medical community. This is a dilemma. The experts who serve as reviewers compete with the work they are reviewing. Leaders in every community, therefore, exert disproportional influence on what gets published. We expect reviewers to be objective and free of conflicts, but in truth, only rarely is that the case.
Albert Einstein once noted that “a foolish faith in authority is the worst enemy of truth.”
