Encore post: Recognizing bogus history, 2

July 3, 2007

Editor’s Note:  I’m traveling this week, celebrating our independence 231 years on.  While mostly out of pocket, I’ll feature some encore posts, material that deserves another look to keep it from fading from memory.  This post, below, is the second of a two-part series from August 2006.

Recognizing bogus history, 2

Bogus history infects political discussions more than others, though there are some areas where bogus history strays into the realm of science (false claims that Darwin and Pasteur recanted, for example).

1. The author pitches the claim directly to the media or to organizations of non-historians, for pay.

Historians are detectives, and they like to share what they find. One historian working in the papers of one figure from history will find a letter from another figure, and pass that information on to the historian working on the second figure. Historians teach history, write it up for scholarly work, and often spin it in more fascinating tales for popular work. Most years there are several good works competing for the Pulitzer Prize in history. Academic historians, those tied to universities and other teaching institutions, join societies, attend meetings, and write their material in journals — all pitched to sharing what they have learned.

Bogus historians tend to show up at conferences of non-historians. Douglas Stringfellow’s tales of World War II derring do were pitched to civic clubs, places where other historians or anyone else likely to know better, generally would not appear (Stringfellow’s stories of action behind enemy lines in World War II won him several speaking awards, and based on his war record, he was nominated to a seat in Congress for Utah, in 1952, which he won; a soldier who knew Stringfellow during the war happened through Salt Lake City during the 1954 re-election campaign, and revealed that Stringfellow’s exploits were contrived; he was forced to resign the nomination). Case in point: David Barton speaks more often to gun collectors than to history groups.

2. The author says that a powerful establishment is trying to suppress his or her work.

Sen. Joseph McCarthy insisted that anyone who opposed his claims that communists dominated certain government agencies, or that any given person was a communist, was because those who challenged him were, themselves, part of the greater conspiracy, trying to silence him. Utah Sen. Arthur V. Watkins, who chaired the committee that recommended censure for Sen. McCarthy, lost his own re-election campaign in 1958 in part to the belief by Utah voters that such a conspiracy existed and had succeeded in suppressing McCarthy.

But there was no organized campaign against McCarthy.  Individual Americans, spurred by patriotism, the Boy Scout Law, or just a sense that truth is valuable, spoke up against him, time and again in many different forums.  Sen. Watkins powerfully opposed communism.  Later historians found any truth in McCarthy’s claims against the State Department and other government agencies, and his critics, got there accidentally, below the usual levels of coincidence.

3. The sources that verify the new interpretation of history are obscure; if they involve a famous person, the sources are not those usually relied on by historians.

Most internet hoaxes simply don’t list sources. Bogus quotes circulating that have been attributed to Madison, Jefferson, Washington, Lincoln, and others, often list a year, and nothing else. When I staffed the Senate, several times a year I’d get letters to work on with claims that the Supreme Court had ruled in 1892 that the U.S. is, officially, a “Christian nation.” Usually there there was no case name attached, but I came to understand that the case referred to was the Church of the Holy Trinity vs. U.S. 1892 was far enough back that it was a difficult case for people outside of a decent law library to get — and then, it is couched in 1892 legalese, which makes it difficult to understand. It is an obscure enough case that most of the time it won’t be checked out. If the case can be produced, rarely will it be among lawyers who can interpret what happened from the fog of the language of the decision. The case is not listed at the Cornell University Law School’s on-line Legal Information Institute, nor at Findlaw.com — the databases they rely on go back to 1893. There is a full text copy at the Justicia website. [This was written in 2007.]

The case involved a law that prohibited the importing of laborers, and the Court ruled that the law probably was not intended to apply to a white, white collar worker, a preacher from England (the law was probably aimed at Chinese workers, coming as it did in that time when immigration from China was prohibited). It appears from the case that the church had argued some First Amendment justification to be exempt, and the U.S. Solicitor General had argued in response that the First Amendment requires the courts to assume that the government is hostile to religion; Justice David Brewer wrote at length about how the nation had accommodated religion over the years, especially Christianity, in dismissing the Solicitor General’s argument (he did not accept the church’s argument, either). This sort of writing is called obiter dicta in legal studies — words of an opinion wholly unnecessary to the decision. The case is cited rarely, and never for its religious “ruling,” because that was not what was ruled, and the language was not applied as law then, nor has it been since.  The Supreme Court ruled that importing preachers from England was not covered by the law. The ruling makes no mention of religion.

A bit of reflection on what really happened in history should make this clear: Consider the effect of such a ruling by the Supreme Court on later cases involving textbooks, busing of parochial students, student prayer, Bible readings, etc. Had such a precedent existed, lawyers would have sniffed it out regardless its obscurity.

4. Evidence for the history is anecdotal.

America’s founders carefully wrote laws that assure religious freedom, largely by creating a separation of state and church. To those unhappy with such a separation, every utterance of a founder in which God is praised, or invoked in any way, becomes “proof” that the founders did not mean what they wrote in the laws. Anecdote trumps any other evidence, to these people.

Abraham Lincoln's letter to the president of the Republican National Convention of 1860, accepting the convention's nomination for the presidency.

Abraham Lincoln’s letter to the president of the Republican National Convention of 1860, accepting the convention’s nomination for the presidency. It was written, you will note, from Springfield, Illinois, 200 miles away from Chicago where the convention was held.

To prove to me the piety of Abraham Lincoln, a fellow showed me photograph of a plaque on a church in Chicago, said to be the church where Abraham Lincoln said his prayers every morning during the Republican Convention of 1860, at which Lincoln got the nomination for president. Other records — newspapers, Lincoln’s letters and other documents, show that, as was the fashion in 1860, Lincoln did not attend the convention in Chicago, but as a candidate for president, stayed at home in Springfield, nearly 200 miles away.

Most real history can be read in documents, and does not need to rely on folk retellings exclusively.

5. The author says a belief is credible because it has endured for some time, or because many people believe it to be true.

Faced with the evidence that a dozen quotes he had attributed to figures such as James Madison, George Washington and Patrick Henry were whole cloth inventions, Texas quote-purveyor David Barton issued a statement urging people not to rely on them because they were “questionable.

A great example of belief triumphing over fact presents itself as the Cardiff Giant, now on display at the Farmers’ Museum in Cooperstown, New York (go visit when you visit the Baseball Hall of Fame). After an argument with a cleric over whether the Bible’s claim that giants once existed, a tobacconist named George Hull hired stonecarvers to carve a giant; then he hired a farmer to bury the carving on his farm, and claim to have struck it when planting. Once discovered the “petrified man” was put on display, for a fee. Hull got lucky: Syracuse businessmen offered to buy it from him for an enormous sum.

Paleontologist Othniel Marsh inspected it on display, and pronounced it a hoax. For some odd reason, that increased the popularity of the attraction. Carnival and side show entrepreneur P. T. Barnum offered $60,000 for the carving, but was refused. Barnum then had a plaster replica made and put on display. The owners of the original hoaxed carving sued, but the suit was thrown out because they could not demonstrate the “genuineness” of their own hoax.  Barnum made more money than the original.  A hoaxed hoax is even more popular than the truth.

6. The author has worked in isolation.

Historians often help each other. Good historians put out queries to many sources, the better to assure accuracy. So, conversely, if there are only a few people who know anything about an account, that fact alone may cause suspicion. Clifford Irving’s hoax biography of Howard Hughes, while remarkably accurate in some regards, was unraveled when enough people familiar with Hughes called the bluff — including, of course, Hughes himself. The book got as far as it did with extreme secrecy on Irving’s part. Working alone makes error easier, and is essential for intentional frauds.

7. The author must propose a new interpretation of history to explain an observation.

Various conspiracy claims require that key people act counter to their known character. If Franklin Roosevelt had “allowed” Pearl Harbor to occur in order to get the U.S. into war, his actions over the previous six years to support Britain start to make little sense. Had Lyndon Johnson been part of a conspiracy to assassinate John Kennedy, his later carrying out the legislative plan of Kennedy runs contrary to all such motivations. If the founders of the U.S. actually intended to make Christianity the state religion, their efforts to disestablish the churches in all 13 colonies, efforts to write bills of rights for each state including freedom of religion, and efforts to create the First Amendment in the Bill of Rights seem like incredible, repeated errors.

Bogus history is much like the conjectured problems that result from time travel: Change one jot of history, and there is a cascading effect on later events. In many cases,were the bogus histories accurate, what follows could not be so, and we wouldn’t be here to discuss it.

Those are the seven warning signs of bogus history. Bogus, or voodoo history should be suspected if two or more of the signs are present — though it is quite possible for actual history to show more than two signs (perhaps actual history could show all seven signs — but I’d have to see an example before stating it’s so).

Encore post: Recognizing bogus history, 1

July 3, 2007

While traveling this week, I’ll feature a few blasts from the past — posts that may merit new attention. This post comes from a two-part series in August 2006:

Recognizing bogus history, 1

Robert Park provides a short e-mail newsletter every Friday, covering news in the world of physics. It’s called “What’s New.” Park makes an art of smoking out bogus science and frauds people try to perpetrate in the name of science, or for money. He wrote an opinion column for the Chronicle of Higher Education published January 31, 2003, in which he listed the “7 warning signs of bogus science.”

Please go read Park’s entire essay, it’s good.

And it got me thinking about whether there are similar warning signs for bogus history? Are there clues that a biography of Howard Hughes is false that should pop out at any disinterested observer? Are there clues that the claimed quote from James Madison saying the U.S. government is founded on the Ten Commandments is pure buncombe? Should Oliver Stone have been able to to more readily separate fact from fantasy about the Kennedy assassination (assuming he wasn’t just going for the dramatic elements)? Can we generalize for such hoaxes, to inoculate ourselves and our history texts against error?

Perhaps some of the detection methods Park suggests would work for history. He wrote his opinion piece after the Supreme Court’s decision in Daubert v. Merrell Dow Pharmaceuticals, Inc., in which the Court laid out some rules lower courts should use to smoke out and eliminate false science. As Park described it, “The case involved Bendectin, the only morning-sickness medication ever approved by the Food and Drug Administration. It had been used by millions of women, and more than 30 published studies had found no evidence that it caused birth defects. Yet eight so-called experts were willing to testify, in exchange for a fee from the Daubert family, that Bendectin might indeed cause birth defects.” The Court said lower courts must act as gatekeepers against science buncombe — a difficult task for some judges who, in their training as attorneys, often spent little time studying science.

Some of the Daubert reasoning surfaced in another case recently, the opinion in Pennsylvania district federal court in which Federal District Judge John Jones struck down a school board’s order that intelligent design be introduced to high school biology students, Kitzmiller v. Dover Area School District.

Can we generalize to history, too? I’m going to try, below the fold.

Here are Park’s seven warning signs, boiled down:

Park wrote:

Justice Stephen G. Breyer encouraged trial judges to appoint independent experts to help them. He noted that courts can turn to scientific organizations, like the National Academy of Sciences and the American Association for the Advancement of Science, to identify neutral experts who could preview questionable scientific testimony and advise a judge on whether a jury should be exposed to it. Judges are still concerned about meeting their responsibilities under the Daubert decision, and a group of them asked me how to recognize questionable scientific claims. What are the warning signs?

I have identified seven indicators that a scientific claim lies well outside the bounds of rational scientific discourse. Of course, they are only warning signs — even a claim with several of the signs could be legitimate. [I have cut out the explanations. — E.D.]

  1. The discoverer pitches the claim directly to the media.
  2. The discoverer says that a powerful establishment is trying to suppress his or her work.
  3. The scientific effect involved is always at the very limit of detection.
  4. Evidence for a discovery is anecdotal.
  5. The discoverer says a belief is credible because it has endured for centuries.
  6. The discoverer has worked in isolation.
  7. The discoverer must propose new laws of nature to explain an observation.

Voodoo history

Here, with thanks to Robert Park, is what I propose for the warning signs for bogus history, for voodoo history:

  1. The author pitches the claim directly to the media or to organizations of non-historians, for pay.
  2. The author says that a powerful establishment is trying to suppress his or her work.
  3. The sources that verify the new interpretation of history are obscure; if they involve a famous person, the sources are not those usually relied on by historians.
  4. Evidence for the history is anecdotal.
  5. The author says a belief is credible because it has endured for some time, or because many people believe it to be true.
  6. The author has worked in isolation.
  7. The author must propose a new interpretation of history to explain an observation.

Any history account that shows one or more of those warning signs should be viewed skeptically.

In another post, I’ll flesh out the reasoning behind why they are warning signs.


Photos of a hoax: The Cardiff Giant

July 2, 2007

David Carlson's pinhole camera photo of a sign promoting the Cardiff Giant

The Cardiff Giant was a great hoax of the 19th century. George Hull, a cigar maker in upstate New York, hired a Chicago sculptor to make a large statute of a man. He then buried the statue on a friend’s farm, and year later hired workmen to dig a well where the statue was buried, and of course the well-diggers “discovered” the statue. Hull’s intent was to hoax Bible literalists who talked about giants in the ground, based on Genesis 6:4.When the statue was discovered, it was claimed to be a petrified giant, evidence of giants living in America. The stone piece was put on traveling display.

The hoax was discovered. That only increased the desire to see the statue, and the price to see it was raised. P. T. Barnum tried to buy the thing, and when his offer was refused, initially he created a hoax of the hoax for his own display.

The Cardiff Giant is on display today at the Farmers Museum in Cooperstown, New York (also home of the Baseball Hall of Fame). Barnum’s fake fake is on display at Marvin’s Marvelous Mechanical Museum, Farmington Hills, Michigan.

The photo at top was created with a grant from the Vermont Council on the Arts by David Carlson, whose website is here (his work is for sale — some of the photos would be good conversation starters in history classrooms) It’s a photo made with a pinhole camera, a camera without a lens. The second photo is from Roadside America, showing the Cardiff Giant as displayed today.


Dembski’s blog caught hoaxing again

June 30, 2007

An acquaintance sends word he’s happy to be back in the mountains with his hammer again, breaking rocks as a geologist in support of a mining venture. The price of gold is high, a few advances in technology have helped the process, and our friend was tapped by suits with money to help keep the actual gold mining operation in the proper vein, so to speak.

Mining is best done with a good scientist on hand to make sure the hole dug out is done right, and to be sure that the digging keeps going for the genuine nuggets.

William Dembski’s blog, Uncommon Descent, has no scientists with any geology training, it appears. But again they’ve been mining, for quotes instead of useful ore, and they’ve come up with fool’s information. Unable to tell the difference between fool’s information and the real stuff, they’ve published the fool’s information for the world to see.

A wise person does not allow fool’s information into one’s information banks. Read the rest of this entry »


Fisking “Junk Science’s” campaign FOR the poison DDT, against Rachel Carson: Point #8, mosquito resistance to DDT

June 29, 2007

This is the second in a series of Fisks of “100 things you should know about DDT,” a grotesquely misleading list of factoids about DDT put up a site called JunkScience.com. While one would assume that such a site would be opposed, this particular site promotes junk science. I’m not taking the points in order.The “100 things” list is attributed to Steven Milloy, a guy who used to argue that tobacco use isn’t harmful, and who has engaged in other hoaxes such as the bizarre and false claim that Compact Fluorescent Lightbulbs (CFLs) can pose serious toxic hazards in your home (and therefore, you should continue to waste energy with less efficient bulbs); and to J. Gordon Edwards, a San Jose State University entomologist who, despite being a great entomologist, was a bit of a nut on some political things; Edwards assisted Lyndon Larouche’s group in their campaign against Rachel Carson before his death in 2004. (Did Edwards actually have a role in the development of this list?)

100 things you should know about DDT

Claim #8. Some mosquitoes became “resistant” to DDT. “There is persuasive evidence that antimalarial operations did not produce mosquito resistance to DDT. That crime, and in a very real sense it was a crime, can be laid to the intemperate and inappropriate use of DDT by farmers, especially cotton growers. They used the insecticide at levels that would accelerate, if not actually induce, the selection of a resistant population of mosquitoes.”

[Desowitz, RS. 1992. Malaria Capers, W.W. Norton & Company]

Cover of The Malaria Capers, by Robert S. Desowitz

Cover of The Malaria Capers, by Robert S. Desowitz

This was what Rachel Carson warned about. Indiscriminate use of DDT, such as broadcast application on crops to kill all insect, arthropod or other pests, would lead to mosquitoes and other dangerous insects developing resistance to the chemical. Of course, resistance developed as a result of overspraying of crops has exactly the same result, in the fight against malaria, as overuse in the fight against malaria.  Cover of The Malaria Capers, by Robert S. Desowitz

Worse, such overuse also killed predators of mosquitoes, especially birds. In an integrated pest management program, or in a well-balanced ecosystem, birds and other insect predators would eliminate a large number of mosquitoes, holding the population in check and preventing the spread of malaria. Unfortunately, when the predators are killed off, the mosquitoes have a population explosion, spreading their range, and spreading the diseases they carry.

Assuming Milloy quoted the book accurately, and assuming the book actually exists, this point says nothing in particular in favor of DDT; but it reaffirms the case Rachel Carson made in her 1962 book, Silent Spring. Contrary to suggestions from the campaign against Rachel Carson, she urged that we limit use of DDT to tasks like preventing malaria, around humans, to preserve the effectiveness of DDT and prevent overspraying.

And then, there is this: Milloy doesn’t bother to quote the first part of the paragraph he quotes, on page 214 of Malaria Capers. Here is what the paragraph actually says:

There were a number of reasons for the failure, not least that the anophaline vector mosquitoes were becoming resistant to the action of DDT both physiologically — they developed the enzymes to detoxify the insecticide — and behaviorally — instead of feeding and wall-resting, they changed in character to feed and then quickly bugger off to the great outdoors. [from this point, Milloy quotes correctly]

In other words, the DDT-based campaign against malaria failed because DDT failed; mosquitoes became resistant to it.  DDT’s declining ability to kill mosquitoes is one of the major reasons DDT use plunged after 1963, and continues to decline to no use at all.

To combat the dastardly campaign of calumny against Rachel Carson and science, you should also read: Deltoid, here, here and here, and the rest of his posts on the topic; Bug Girl, here, at least, and here, and the rest of her posts; denialism, here; and Rabett Run, here.

Cold, Clear and Deadly

June 28, 2007

Title of a book that documents and discusses the omnipresence of DDT and related pesticides in waters all over the world, even in places far from any known application, such as the Arctic and Antarctic.

Author Melvin J. Visser wrote a tribute to Rachel Carson at his blog, also called Cold, Clear and Deadly.

Fisking “Junk Science” and “100 things you should know about DDT”: A new project

June 27, 2007

Looking at the odd campaign against the reputation of Rachel Carson, conducted largely by a group of corporate-paid, political scalawags, one will eventually come across a site named JunkScience.com, which has as a motto, “All the junk that’s fit to debunk.”

One might be forgiven if one assumes that the site debunks junk science claims. But that does not appear to be it’s aim at all. On this page, for example, “100 things you should know about DDT,” the site perpetrates or perpetuates dozens of junk science claims against Rachel Carson, against public health, against government and against reason. The site promotes junk science, rather than debunking it!

For example, I had just read a chunk of history reminding me that our first Environmental Protection Agency Administrator, William Ruckelshaus, had been ordered by a federal court to review the pesticide certification for DDT, and had acted against DDT only after two different review panels recommended it be phased out, and states had already started bans of their own. At the time, in 1972, Ruckelshaus faced a heap of criticism for moving so slowly on the issue.

How is this action described at JunkScience.com?

You wouldn’t quite recognize the events — and I doubt you could verify other oddities the JunkScience.com site claims:

17. Extensive hearings on DDT before an EPA administrative law judge occurred during 1971-1972. The EPA hearing examiner, Judge Edmund Sweeney, concluded that “DDT is not a carcinogenic hazard to man… DDT is not a mutagenic or teratogenic hazard to man… The use of DDT under the regulations involved here do not have a deleterious effect on freshwater fish, estuarine organisms, wild birds or other wildlife.”

[Sweeney, EM. 1972. EPA Hearing Examiner’s recommendations and findings concerning DDT hearings, April 25, 1972 (40 CFR 164.32, 113 pages). Summarized in Barrons (May 1, 1972) and Oregonian (April 26, 1972)]

18. Overruling the EPA hearing examiner, EPA administrator Ruckelshaus banned DDT in 1972. Ruckelshaus never attended a single hour of the seven months of EPA hearings on DDT. Ruckelshaus’ aides reported he did not even read the transcript of the EPA hearings on DDT.

[Santa Ana Register, April 25, 1972]

19. After reversing the EPA hearing examiner’s decision, Ruckelshaus refused to release materials upon which his ban was based. Ruckelshaus rebuffed USDA efforts to obtain those materials through the Freedom of Information Act, claiming that they were just “internal memos.” Scientists were therefore prevented from refuting the false allegations in the Ruckelshaus’ “Opinion and Order on DDT.”

I propose to Fisk much of the list of 100 claims against Carson (which is really a list over 100 items now), in a serial, spasmodic fashion. I’ll post my findings here, making them generally available to internet searches for information on Rachel Carson and DDT. Below the fold, I’ll start, with these three specious claims listed above.

Didn’t know insanity is contagious: Sen. Tom Coburn

June 27, 2007

Several outbursts of insanity in Washington, D.C., lately make one wonder if there is some contagious disease that prompts these outbursts.

Although, I must admit, this outburst was before the Cheney/Snow claims that the nation’s chief executive and vice chief executive are not executive branch members.

In a flash of irony that shattered irony meters across libraries, laboratories and the research facilities in Oklahoma universities, Oklahoma’s U.S. Sen. Tom Coburn placed a hold on the bill to name a post office in honor of Rachel Carson, accusing Carson of “junk science.” What Coburn failed to say — or, God forbid, failed to notice — is that the criticisms of Carson are truly junk science.

In the Washington Post Coburn offered this inexplicable explanation:

In a statement on his Web site yesterday, Coburn (R) confirmed that he is holding up the bill. In the statement, he blames Carson for using “junk science” to turn public opinion against chemicals, including DDT, that could prevent the spread of insect-borne diseases such as malaria, which is spread by mosquitoes.

Coburn, whose Web site says he is a doctor specializing in family medicine, obstetrics and allergies, said in the statement that 1 million to 2 million people die of malaria every year.

“Carson was the author of the now-debunked ‘The Silent Spring,’ ” Coburn’s statement reads. “This book was the catalyst in the deadly worldwide stigmatization against insecticides, especially DDT.”

This issue is arcane enough that history aficionados reading may not be fully aware of the problems with Coburn’s claims. Let me explain.

First, Carson didn’t complain about insecticides, but instead pointed out that overuse of some insecticides is damaging to the environment, and ultimately frustrates their use as intended. As Carson pointed out, DDT was ceasing to be effective in the fight against malaria due to this overuse. In other words, Carson’s advocacy, if it was as effective as Coburn imagines, saved DDT as an effective tool in the fight against malaria. But Coburn blames her for the opposite. It’s as if he were treating a kid who fell out of a tree, and he blamed the broken arm on a cold virus, because the kid’s nose was running.

Second, DDT is a deadly killer. It’s not like DDT is perfectly harmless. Carson, using studies by insecticide manufacturers and entomologists accumulated over the previous 20 years, pointed out that broadcast use of DDT to protect cotton from boll weevils not only failed to protect the cotton, it also endangered humans. Overuse of any insecticide tends to drive evolution of resistance in the insects targeted, and this is exactly what happened, and what Carson reported. That’s not junk science in any form. It’s accurate, real science, that benefits humans.

Had Carson’s book not appeared when it did, it is quite possible, maybe even likely, that it would have been rendered completely useless against insects.

But even worse, animals don’t evolve resistance as quickly as insects can, and the levels of DDT and its daughter compounds were multiplied in living things as they were higher in a local food chain. DDT is absorbed into living tissues very effectively, so it does not remain floating about, say, in the water of a swamp where it is sprayed for mosquitoes. Instead it is absorbed by other insects, by plants, and then by the animals that consume those insects and plants, and then by the predators at the top of the food chains. Carson was way ahead of her time in understanding this relationship, but the science at the time supported her conclusions exactly, and every study done since then has reinforced Carson’s reporting of the scientific conclusions.

This was important because, as concentrated especially in birds, DDT and its daughters cause eggs to be non-viable, and it even changes the behaviors of birds in raising their young. DDT kills the next generation of birds. It is especially deadly against raptors at the top of the food chain — America’s symbol, the bald eagle, for example, was driven to the brink of extinction by DDT — but it also kills the songbirds which, in a well-balanced ecosystem, keep mosquito populations down and prevent the spread of mosquito-borne diseases like malaria or dengue fever.

So DDT use, as Sen. Coburn appears to defend it, would have left the world malaria and mosquito-ridden, exactly the opposite of his claims.

Third, Carson’s book has been verified in hundreds of studies. To call it “debunked” is either a total purchase of junk science, or a dastardly distortion of the the facts. Carson worried that DDT might be a cause of cancer, a carcinogen. Knowledge of carcinogens was so limited when she wrote that Congress and the medical establishment — two groups Coburn belongs to — endorsed the Delaney Clause to the Food and Drug Act in 1957, ordering that nothing that caused cancer be allowed as an additive in foods or food supplements. This seems almost naive today, when we know that some things, like selenium, are both essential nutrients and carcinogenic, and when we can detect vanishingly small traces of carcinogens in almost everything. Carson called our attention to potential dangers of DDT.

And, it turns out, she was mostly right about DDT and cancer. The good news is that DDT is not a potent carcinogen in humans that we know. Coburn appears to rest his entire case on a misunderstanding of that last sentence. Anti-Carson screeds tend to note that DDT has not been found to be a major cause of breast cancer in women. While true, that study leaves these facts: DDT is a known carcinogen in mammals (and we know of no carcinogen that affects other mammals that is not also a carcinogen for humans, who are mammals); DDT’s effects would be expected to show up in liver cancer, because DDT is a toxin and toxins damage the liver even as the organ does its job in cleaning the toxin out; DDT is a known toxin to human livers, causing liver damage leading to liver disease. Liver disease is a frequent precursor to liver cancer. We need more studies, but it is simply false to say that we know DDT is not a carcinogen. DDT is a carcinogen; the only thing we don’t know is how potent it is in humans.

So here we have Sen. Coburn, an MD in the Senate, a man who has the training of a scientist, a guy who used to practice medicine, helping people avoid things that harm or kill them, falling victim to junk science claims about Rachel Carson and her work, and DDT and what it does, and how it does it.

It ain’t the things we don’t know that get us into trouble, some wag once said: It’s the things we know that ain’t so.

Perhaps you could drop Dr. Coburn a letter, gently inform him of the facts, and ask that he release the hold on honoring Rachel Carson, winner of the Presidential Medal of Freedom, the woman who saved DDT from becoming a useless limb in the war against insect-borne disease? It would be the patriotic thing to do.


Rachel Carson’s honor defended

June 25, 2007

Bug Girl sleuthed around a bit, and found information from official sources that really demonstrates the critics of Rachel Carson are using Gillette Foamy to make us think “mad dog!”

DDT concentration in the food chain - USFWS

Chart from US Fish and Wildlife Service (USFWS) illustrates biomagnification, by which a minuscule dose of DDT to small plankton gets magnified a few million times by the time the top predators in the food chain get it.

So the evidence continues to pile up that Rachel Carson was simply a fine writer, a good scientist, and correct about DDT’s dangers.

Check out the Fish and Wildlife Service’s site, here; notice especially their structure of the site, to dispel the falsehoods.

FWS quotes Carson on DDT use:

In Audubon magazine she wrote, “We do not ask that all chemicals be abandoned. We ask moderation. We ask the use of other methods less harmful to our environment” (4). Countering claims that she was advocating a back-to-nature philosophy, she said, “We must have insect control. I do not favor turning nature over to insects. I favor the sparing, selective and intelligent use of chemicals. It is the indiscriminate, blanket spraying that I oppose” (5).

Evidence mounts that claims against Rachel Carson are sheer calumny. While the political motivations of this smear campaign are not clear, we don’t need to know for certain who is telling lies about a great American hero, or why. As Americans, as concerned citizens, as teachers and parents — as patriots — we only need to know that the claims against Rachel Carson are false.

And now it is our duty to call on Oklahoma’s Sen. Tom Coburn to stop the campaign against Carson. Coburn is the point man in the smear campaign right now: He has put a committee hold on the well-intentioned, justified bill to name a post office in her hometown after Rachel Carson. It is time for Tom Coburn to stand up and do the right thing for a great American. Sen. Coburn needs to lift his committee hold and allow committee action on this minor honor.

Setting the record straight on Rachel Carson, malaria and DDT

June 19, 2007

The contemptible campaign of hoax and calumny against the work and memory of Rachel Carson continues. You should read more at the sites I cite near the end of this post.

The key false claim of the Carson critics is that, but for the ban on DDT, millions of lives would have been saved over the past 30 years. Chief problem with the claim is that national bans on DDT all preserve DDT use for essential mosquito eradication, especially if there are no other tools to fight the disease. But other problems with the claim include the fact that DDT had stopped being highly effective by the late 1960s; eradication was a pipe dream, and mosquitoes developed resistance to DDT.

That doesn’t stop the critics. So, Dear Reader, when you read criticisms of Rachel Carson and hear the pseudo-science whine that Carson alone has condemned millions to death by malaria, I want you to keep in mind this question: If DDT were such an effective tool against malaria, why didn’t the World Health Organization fight to keep it? Why didn’t the manufacturers fight to keep it? Why would more than 150 nations, tens of thousands of scientists, tens of thousands of health workers, and conservative “I-told-you-so” skeptics who hate environmentalists, all simultaneously fall asleep?

The answer is, Dear Reader, they didn’t all fall asleep. DDT stopped being effective, and malaria fighters realized there were other problems — the parasites that the mosquitoes spread also became resistant to anti-malaria drugs, a bigger problem than DDT resistance. People and organizations who fight malaria did ask that use of DDT be preserved for spraying to fight malaria; but they didn’t defend it against bans on other use because those bans help the malaria fighters.

Below the fold, I offer two quotes from Saving Lives, Buying Time: Economics of Malaria Drugs in an Age of Resistance (2004) Board on Global Health (BGH) (available from the National Academy of Sciences). You can see that DDT is not the golden-egg-laying goose, and that consequently Rachel Carson is not the mindless ogre she is made out to be in recent invectives.

How many WorldNet Daily hoaxes does it take to change a light bulb?

June 6, 2007

Earlier I pointed to a hoax article foisted by WorldNet Daily, claiming families would face exorbitant hazardous waste clean up costs if they broke a compact fluorescent lightbulb (CFLs).

Not only did WorldNet Daily never apologize to its readers, the paper is at it again, campaigning in favor of pollution and global warming, trying to scare people who switch to lights other-than-tungsten.

Hoaxmeister Joseph Farah uses an over-the-top, breathless tone: HEAT OF THE MOMENT
Light-bulb ban craze exceeds disposal plans
Facts about CFLs, heir to incandescents, downplayed in government-enviro push”

Could anyone take that seriously? As Dave Barry used to say, “I could not make this up,” the “danger” from CFLs shows up in serious discussion forums. This forum, inaptly titled “Straight Talk,” demonstrates that people really do believe such hoaxes, especially about things they know very little about, like mercury poisoning.

Folks, five will get you ten, if you told these people about massive mercury poisoning that really exists in the Hudson River, and warned them against eating fish caught there, they’d claim you were an alarmist tree-hugger and laugh it off — though the mercury levels and potential for health-damaging exposure are both significantly greater for fish caught in some rivers, like the Hudson, than they are for broken CFLs.

But just try to suggest a small way to work against global warming, and they’ll pull out that same mercury poisoning argument to justify doing nothing and letting pollution win.

A warning to these people to “use your head” goes completely unheeded, heads having been lost some time earlier.

Here’s an example of just how far Farah twists the facts in order to make his hoax case against CFLs. First, Farah all but calls CFLs a communist plot (he claims the move to use them started in Cuba, under Castro — a dubious claim at best, and funny any way you cut it). Then he points to a Swedish firm marketing the bulbs in the U.S. — them furriners can’t be trusted, Farah implies. The firm is IKEA — never mind they are fine examples of capitalism run rampant. Third, Farah cites an editorial in Waste News , but makes it appear the publication said something the opposite of what it said.

Here’s what Farah wrote:

Those who really care about this problem right now are those involved in the waste industry.

“Most agree more energy-efficient light bulbs can significantly curb air pollution, but fewer people are talking about how to deal with them at the end of their lives,” explained a page 1 story in the April 2 issue of Waste News. It goes on to explain “there is no plan to address air and water pollution concerns that could develop if consumers improperly dispose of the mercury-containing devices.”

Gee, that’s pretty dire. No plans at all for disposal? Are we getting a pig in a poke?

Waste News actually said the bulbs are a “significant” environmental improvement. They point out weaknesses in current recycling, but they stop way short of urging people not switch to CFLs — here, read for yourself, the conclusion Waste News draws is quite a bit at odds with Joseph Farah’s version.

Managing CFL endgame
Waste News, April 02, 2007

Compact fluorescent light bulbs are a hot environmental trend these days, and with good reason. They require substantially less energy than traditional incandescent bulbs and last several times longer. Used on a large scale they can dramatically reduce our energy needs and therefore the pollution we create. With their longer life they’re ultimately an economical choice as well.

But CFL bulbs aren’t perfect. They contain mercury, albeit a small amount compared with mercury thermometers, automotive switches and the standard 4-foot fluorescent lamp. Still, there’s no large-scale plan in place to manage the end-of-life handling of these bulbs, and having the mercury end up in the environment certainly is undesirable.

Strong warnings about the need for proper disposal could dissuade customers from buying CFLs, which most people believe are far better environmentally even with their mercury – an element essential to their energy efficiency. Consumers also could get confused about what types of bulbs to throw away and pitch ones with higher mercury. Broken bulbs also pose multiple health risks to waste haulers. Meanwhile, more governments are moving to ban mercury from disposal.

Pressure will be on manufacturers to take responsibility for this. Sylvania is one lighting company that has started to do so, offering take-back programs that involve a fee for consumers. And several lighting companies have agreed to voluntarily limit the mercury content of lower wattage CFL bulbs.

Lighting producers need to continue on this course, and do so sooner rather than later, even though the issue may be years away because sales are still small and the bulbs’ long life makes wide-scale disposal relatively distant. But a sound plan for the products’ end will remove a potentially big obstacle to a significant environmental improvement.

Hello? I thought there were no plans to do anything, according to Waste News — but when I read the article, it says Sylvania already has a program and others are ready to go. Is there no standard of ethics at WorldNet Daily?

Bogus science palace puts blot on Memorial Day remembrances

May 27, 2007

There’s not much to add, beyond the three-quarters of a hundred entries in the one time Ken Ham’s Creation Museum blog carnival, hosted at Pharyngula by P. Z. Myers.

Those we honor on Memorial Day fought, and died, to preserve Ken Ham’s right to believe any fool thing he wants to believe.  That’s part of the ironic beauty of our Constitution and those who fight to defend it.

Having a right to believe any fool thing, and promoting fool ideas with $27 million given by people who expected one to tell the truth, are probably separate, different things.


Historical fiction: Churchill and Fleming, and antibiotics

May 26, 2007

Is this old dead duck still circulating?

The story is that a poor farm kid in England Scotland saves a rich kid from drowning, and the rich family offers to pay for college for the poor kid. The poor kid goes to college, and later makes a great discovery, and that discovery later saves the life of a member of the rich family, who goes on to save the world.

Churchill in Tunisia, 1943, visiting New Zealand’s 2nd Division, with Bernard Freyberg, known as Tiny

In various forms I’ve seen this story, that a member of the Churchill family, or Winston Churchill himself, was saved by a member of the Fleming family, or Sir Alexander Fleming himself (the discoverer of penicillin). Then, years later Churchill has a deadly infection, but his life is saved by Fleming’s discovery.

It’s a great story, actually, but it is fabrication from start to finish, laced with famous names, our natural ignorance of some parts of history, and our desire for such coincidences to be true. It’s such a great story that the wrong, hoax version still circulates even after it is so easy to learn that the story is wrong.

The Churchill Centre, in England, has a denial that should be embarrassing to Americans and Christians — they point out it was distributed in the 1950s by churches here.

The story apparently originated in Worship Programs for Juniors, by Alice A. Bays and Elizabeth Jones Oakberg, published ca. 1950 by an American religious house, in a chapter entitled “The Power of Kindness.”

Here are several ways to tell the story is false: Read the rest of this entry »


Mining the Internet Archive: Tobacco, history and controversy

May 22, 2007

European Union rules require member states to do something about indoor air pollution. European states are banning smoking in public places. Gone soon will be days when we can joke about Britons and their Player’s cigarettes, or the French and their Galois habits.

Every once in a while as I recount the great Tobacco/Health Wars, my kids remind me that they never saw a cigarette commercial on television. Once, we caught a showing of past ads, and I was truck nostalgic by Fred Flintstone’s testimony for Winston cigarettes — the kids gasped: “Fred Flintstone used to smoke!”

Everybody smoked, once upon a time, it seemed. 1940s and 1950s magazines have ads in which doctors and athletes claim cigarette smoking is either unharmful, sheer pleasure, or even health promoting. Got a cigarette cough? Switch to menthol cigarettes! Mouth burns? Try a filter cigarette.

Today, kids wonder why Virginia did so well selling tobacco to Britain — who in their right mind would have smoked? they ask.

The Internet Archive has an abundance of film material on tobacco. The films come from the University of California – San Francisco: Read the rest of this entry »


Brownback parody, or Brownback lunacy?

May 20, 2007

Okay, I think this site is a parody, a hoax, on U.S. Sen. Sam Brownback‘s presidential campaign.

But it’s difficult to tell, especially when stuff like this voodoo history is on Brownback’s official campaign site. Alvin Reed thinks Brownback understands “the creator” better than other candidates because he was Secretary of Agriculture in Kansas, and that made Brownback ‘closer to the soil?’

Brownback is one of the three Republicans who confessed to supporting creationism, so he has no chance of my vote in any case. All the same, I’d prefer lunatics stay out of the presidential campaign.

I have written the Brownback campaign asking them for an explanation of the heliocentrism stuff. If they are not savvy enough to have a disavowal of the Blogs4Brownback out, and the sites are not part of the campaign, he’s going to get toasted quickly.

But if the site is affiliated with him, he deserves to get toasted more quickly — already there are serious posters there defending Brownback. Someone needs to tell them Jesus died to take away their sins, not their brains ©.
