The Seven Warning Signs of Bogus Science By ROBERT L. PARK
The National Aeronautics and Space Administration is investing close to a million dollars in an obscure Russian scientist's antigravity machine, although it has failed every test and would violate the most fundamental laws of nature. The Patent and Trademark Office recently issued Patent 6,362,718 for a physically impossible motionless electromagnetic generator, which is supposed to snatch free energy from a vacuum. And major power companies have sunk tens of millions of dollars into a scheme to produce energy by putting hydrogen atoms into a state below their ground state, a feat equivalent to mounting an expedition to explore the region south of the South Pole.
There is, alas, no scientific claim so preposterous that a scientist cannot be found to vouch for it. And many such claims end up in a court of law after they have cost some gullible person or corporation a lot of money. How are juries to evaluate them?
Before 1993, court cases that hinged on the validity of scientific claims were usually decided simply by which expert witness the jury found more credible. Expert testimony often consisted of tortured theoretical speculation with little or no supporting evidence. Jurors were bamboozled by technical gibberish they could not hope to follow, delivered by experts whose credentials they could not evaluate.
In 1993, however, with the Supreme Court's landmark decision in Daubert v. Merrell Dow Pharmaceuticals, Inc. the situation began to change. 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.
In ruling that such testimony was not credible because of lack of supporting evidence, the court instructed federal judges to serve as "gatekeepers," screening juries from testimony based on scientific nonsense. Recognizing that judges are not scientists, the court invited judges to experiment with ways to fulfill their gatekeeper responsibility.
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.
1. The discoverer pitches the claim directly to the media. The integrity of science rests on the willingness of scientists to expose new ideas and findings to the scrutiny of other scientists. Thus, scientists expect their colleagues to reveal new findings to them initially. An attempt to bypass peer review by taking a new result directly to the media, and thence to the public, suggests that the work is unlikely to stand up to close examination by other scientists.
One notorious example is the claim made in 1989 by two chemists from the University of Utah, B. Stanley Pons and Martin Fleischmann, that they had discovered cold fusion -- a way to produce nuclear fusion without expensive equipment. Scientists did not learn of the claim until they read reports of a news conference. Moreover, the announcement dealt largely with the economic potential of the discovery and was devoid of the sort of details that might have enabled other scientists to judge the strength of the claim or to repeat the experiment. (Ian Wilmut's announcement that he had successfully cloned a sheep was just as public as Pons and Fleischmann's claim, but in the case of cloning, abundant scientific details allowed scientists to judge the work's validity.)
Some scientific claims avoid even the scrutiny of reporters by appearing in paid commercial advertisements. A health-food company marketed a dietary supplement called Vitamin O in full-page newspaper ads. Vitamin O turned out to be ordinary saltwater.
2. The discoverer says that a powerful establishment is trying to suppress his or her work. The idea is that the establishment will presumably stop at nothing to suppress discoveries that might shift the balance of wealth and power in society. Often, the discoverer describes mainstream science as part of a larger conspiracy that includes industry and government. Claims that the oil companies are frustrating the invention of an automobile that runs on water, for instance, are a sure sign that the idea of such a car is baloney. In the case of cold fusion, Pons and Fleischmann blamed their cold reception on physicists who were protecting their own research in hot fusion.
3. The scientific effect involved is always at the very limit of detection. Alas, there is never a clear photograph of a flying saucer, or the Loch Ness monster. All scientific measurements must contend with some level of background noise or statistical fluctuation. But if the signal-to-noise ratio cannot be improved, even in principle, the effect is probably not real and the work is not science.
Thousands of published papers in para-psychology, for example, claim to report verified instances of telepathy, psychokinesis, or precognition. But those effects show up only in tortured analyses of statistics. The researchers can find no way to boost the signal, which suggests that it isn't really there.
4. Evidence for a discovery is anecdotal. If modern science has learned anything in the past century, it is to distrust anecdotal evidence. Because anecdotes have a very strong emotional impact, they serve to keep superstitious beliefs alive in an age of science. The most important discovery of modern medicine is not vaccines or antibiotics, it is the randomized double-blind test, by means of which we know what works and what doesn't. Contrary to the saying, "data" is not the plural of "anecdote."
5. The discoverer says a belief is credible because it has endured for centuries. There is a persistent myth that hundreds or even thousands of years ago, long before anyone knew that blood circulates throughout the body, or that germs cause disease, our ancestors possessed miraculous remedies that modern science cannot understand. Much of what is termed "alternative medicine" is part of that myth.
Ancient folk wisdom, rediscovered or repackaged, is unlikely to match the output of modern scientific laboratories.
6. The discoverer has worked in isolation. The image of a lone genius who struggles in secrecy in an attic laboratory and ends up making a revolutionary breakthrough is a staple of Hollywood's science-fiction films, but it is hard to find examples in real life. Scientific breakthroughs nowadays are almost always syntheses of the work of many scientists.
7. The discoverer must propose new laws of nature to explain an observation. A new law of nature, invoked to explain some extraordinary result, must not conflict with what is already known. If we must change existing laws of nature or propose new laws to account for an observation, it is almost certainly wrong.
I began this list of warning signs to help federal judges detect scientific nonsense. But as I finished the list, I realized that in our increasingly technological society, spotting voodoo science is a skill that every citizen should develop.

It's a correlation. Correlation is not causality.
QM predicts the correlation without postulating any sort of signal from one measurement event to another. That shows you that, mathematically, there need not be any causal influence from one to the other.
But that being said, the long-range correlations are an observed experimental fact. It's up to you whether you want to reject QM on the grounds that it predicts long-range correlations. But please be aware that any correct theory must also (quantitatively) make the same prediction, because the correlations really are there in nature.
The problem is that the American Academy of Science and most scientific organizations would follow the established 'party-line'.
Most revolutionary breakthroughs in science must cut through this inertia, a difficult and grueling undertaking...
1. The discoverer pitches the claim directly to the media - yes, frequently
2. The discoverer says that a powerful establishment is trying to suppress his or her work - yes, often "big oil" is blamed
3. The scientific effect involved is always at the very limit of detection - yes, we've been told it'll be 30 years before we can determine if the oceans are rising or not, plus other examples
4. Evidence for a discovery is anecdotal - yes, "sure was a hot day yesterday...must be global warming"
5. The discoverer says a belief is credible because it has endured for centuries - no.
6. The discoverer has worked in isolation - no.
7. The discoverer must propose new laws of nature to explain an observation - yes
Global warming gets 5 out of 7. Sounds like junk science to me.
He needs a better example...although it got lost in all the initial furor about the Pons/Fleishmann experiment, there has been quite a bit of further work on this subject in the past decade or so (or so I read in a variety of magazines).
Although there is still debate about whether this is fusion or not, there have been quite a few, repeatable, experiments which result in more energy coming out of the experiment than was put in.
Might be a chemical reaction of some kind, might be something else. But, clearly, something is happening.
The measurments are statistical, which prevents information transfer. At least that's what's being claimed.
Actually, the ace and queen would be examples of local hidden variables. We would expect such correlations to respect Bell's Inequality, whereas quantum correlations do not. There really is no classical analog.
I wrote a layman's explanation of what Bell's Inequality is, and why its violation is so puzzling, but it's not as clear as I would like it to be.
That's totally revisionist history. QM definitely wasn't accepted quickly.
As for point four, classic quackery.
I was agreeing with the original post. Claims of car companies buying up inventions to suppress them is a sign of quackery.
It certainly was. It was developed almost entirely between 1925 and 1927. In 1929, de Broglie was awarded the Nobel Prize. In 1932, Heisenberg received it. In 1933, Schrödinger and Dirac received it. By that time, only Einstein and a handful of others had a problem with it.
Hmmmmm, I seem to remember somebody talking about laboring in isolation in their attic la-BOR-atory, with his mascot, "Plato" the Platy, on an anti-gravity machine.........
Im not sure where to look for a resource on this. Could you point me to some reference on it?
Thanks
Good FReepin' job!!!
So, Mike, what color is an electron?
Think I can get some investors? :)
Finally, the truth comes out as to who does the heavy lifting.
;-)
Not as long as your diagram shows "N" repelling "S" and "S" attracting "S"..........
;-)
True. It has always seemed politically counterproductive to argue reflexively against environmentalism. Attacks against environmental wacos should be sound and based on science. There have been politicians in recent memory who argued environmentalism wasn't necessary because end times were near. Sheesh. Talk about shooting yourself in the foot.
