ABOUT THE AUTHOR
Dr. John Richard Schrock received his doctorate in entomology from the University of Kansas and is Professor of Biology at Emporia State University.
Nearly every grocery check-out counter in the United States now displays tabloid newspapers that purvey as entertainment a wide array of assertions about movie stars, aliens from other planets, cancer cures. Therefore it is common for a teacher who maintains an open and intellectually exciting classroom atmosphere to hear a wide range of questions from students: “Is such-and-such really true?” And in many cases where the tabloids cite “scientists,” students will want to know: “Do scientists really say that?”
Since it may take considerable coursework and experience to develop a scientific viewpoint toward life, the teacher faces a difficult task providing students with a brief but correct glimpse of how "science" would approach such varied and specific items. A proper response depends on knowing both how scientists operate in general and on some knowledge of the science involved. This issue of the Kansas School Naturalist strives to help the public school teacher clarify some recent pseudoscience in the fields of zoology and botany.
IS IT SCIENCE OR PSEUDOSCIENCE?
When responding to a student’s question, “Is this really science?” or “Do scientists really say this?,” it is wise to consider placing claims in one of three groups. This will not come naturally to most people, because (thanks to Aristotle) our Western tradition and language is set up to classify things as good or bad, up or down, and “science” and “non-science.”
First, there are claims that simply cannot be true if the world operates according to our current experiences and the rules as we have found present in the past (i.e. objects do not fall upward on the earth). If such claims do not stand up to scrutiny and test, a teacher can feel fairly confident stating they are definitely not science.
On the other side are observations that do fit well with our present understanding; they have been observed and they are repeatable in lab or field situations. This is solidly science. of course it will take some science knowledge on the part of the teacher and student, and an ability to search out the current literature, to determine both of these cases.
|Definitely "outside science" as we understand it now||"Unproven" but not impossible pending further evidence||Definitely "within science"|
The middle category is for problem phenomena that are rare or for which the evidence is not conclusive that "could" exist according to natural laws as we currently understand them; we just have to wait for enough instances to amass, or for a successful demonstration to occur, or for a conclusive test, to exclude these claims.
WHAT ABOUT THE "SCIENTIFIC METHOD?"
A science teacher has a complex task in helping students understand how a scientist operates. Although there is a “method” described in textbooks as the “scientific method” composed of some formulation of observation-hypothesis-test-results-new hypothesis . . . etc., real science breakthroughs rarely conform to this formula and the teaching of this formula simply does not accelerate research. If school students read detailed accounts of Fleming’s “discovery” of penicillin, Pasteur’s work with rabies, Watson and Crick’s DNA work, or most of the scientists profiled in past Scientific American articles, they would discover that it takes some stretching to make many of these ventures fit the “scientific method” formula. On the other hand, these scientists did work with a general attitude toward the world, a complex attitude that is summarized on pages 8 and 9.
LOOK AT REAL SCIENCE RESEARCH AND HOW IT WAS DONE
Present some original experimental history that reveals how real human beings with human shortcomings worked on interesting puzzles until they found solutions that are today's science. This history also often reveals the limitations of that understanding.
Real science is also considerably different from what is purveyed in textbooks. Students who hear for the first time a scientist present a paper in a scientific meeting are surprised to hear researchers actually argue! All of those set values in the text actually have some “wiggle” and there is a cutting edge of discovery that is constantly refining our understanding and providing exceptions to nearly every general rule! Students can only perceive these important aspects of science if you introduce them to some original investigations or elaborate debates on real science occurring today. Scientific American articles reporting research from before the 1970s and summary articles on current research in Science News will help provide the flavor of real science, too. Textbooks will not.

USE REALITY IN EVERYDAY TEACHING
Minimize abstractions (such as wordy statements of science concepts) and keep students involved with real lab and field work so what you do talk about will be “meaningful.” These real experiences provide opportunity for real interaction, they test true, and the student realizes that this phenomenon can lead to real consequences.
Minimizing abstractions means moving away from the common practices used in the classroom (reading, talking, showing slides and movies) and using real lab and field activities. The goal is to practice students in securing real information from the real world. (Be careful, not all “hands on” activities deal with the real world.)
Students who currently learn science as a written body of facts also correctly detect that the "facts" change over time. We are actually teaching these students to view controversies as “book thumping” contests where one authority is challenging another. Real science has nothing to do with “authority.”
Students also realize that all the abstract classroom methods are subject to fraud. Texts, pictures, videotapes... all are easily contrived to show what an author or propagandist wishes to show. The real phenomenon on the other hand has all the truth in it for investigation. A good science student will develop a healthy disrespect for anything that is not based on direct evidence.
REQUIRE “REASONING” IN COURSEWORK
Force students to use reason to figure out the world around them by not giving them the “correct” answer. Set up the problem and let them solve it, and help them maintain a rigorous and reasoned discussion.
Reason is developed by practice. The sun may “appear” to rise in the east and set in the west, so observation of the real world alone does not insure the development of a “scientific attitude.” By asking questions and pointing out additional student experiences, a teacher can help students recognize that this is an “apparent motion” of the sun better explained as due to the earth turning.
GENERAL CLASSROOM STRATEGIES
The following checklist may help some teachers steer away from science as an authoritarian body of knowledge:
-Use real specimens wherever possible to illustrate concrete objects. This applies to all levels. There is some educational mythology about abstractions being “better” for older students–it is unproved.
-Use real laboratory experiences where possible to demonstrate real interactions and real consequences. Open (not cookbook) experiments and dissections are vital to provide the student with “meaning” for those terms and concepts and to sharpen the student’s powers of observation.
-Use field experiences wherever possible, minimizing the carry-along social subculture of the classroom and again focusing the student on the phenomena in nature.
-Do not rely heavily on dictionaries and encyclopedias to define terms for students; do not reply to questions with “Look it up,” but rather “Look and see” in the lab or field. If the reality shows one result and the book another, the book loses!
-Avoid pressing students to make up their minds on an issue in the absence of real and first-hand evidence or before they have engaged in reasoned discussion with others; this usually results in the perpetuation of societal prejudices and forms a bad intellectual habit.
-Focus on students’ real experiences as a base for definition; capitalize on those students with first-hand experiences and encourage them to share what they know. (Note: Courts only recognize first-hand testimony and reject hearsay evidence).
-Constantly point out the difference between the value of information from persons who are “book learned” but not testable witnesses (as teachers often are) and persons with first-hand experience who are testable witnesses.
-Point out cases where two students perceive the same picture, event, or situation differently and note how our previous experiences actually change the way we see things; capitalize on the perspective of foreign-born students in class.
Your grandparents would have laughed at the idea of playing music to your houseplants to help them grow. However, with the publication of the best-selling The Secret Life of Plants in 1973 by Tompkins and Bird, a substantial number of Americans embraced some botanical nonsense and much of it still lingers in our public domain. People who would never give credence to UFO’s were easily won over to the unlikely claim that plants can detect when you approach with a razor and herbicide on your mind, or that plants will grow to please you, or that humans and plants have force fields and auras! “Do you sing to your plant” will more likely draw a sober reply than an incredulous chuckle. Acceptance of this plant mysticism was high because the “Secret Life” book purported to report a wide array of solid “scientific experiments,” thus making this one of the most elaborate modern cases of pseudoscience known. Some assertions and possible teacher strategies follow:
“Whether awake or asleep, we ought to never allow ourselves to be persuaded of the truth of anything unless on the evidence of our reason. And it must be noted that I say of our reason, and not of our imagination or our senses.”
TWENTY “SCIENCE ATTITUDES”
. . . modified from Bronowski (1978), Diederich (1967), and Whaley & Surratt (1967).
In 1966, a researcher named Backster connected a plant to a polygraph and reported that plants responded to his intent to damage the plant. He reported that electrodes that usually measure galvanic skin response in humans were tracing a response to his decision to burn a leaf with a match before he reached for the book of matches! The plant was obviously reacting to his thoughts, he concluded.
-Do polygraphs really indicate people’s thoughts when used as “lie detectors” aside from their use here?
-How “big” were the experimental results on the chart compared to random “noise”?
-Were the results repeatable? Were readings the same when the same experimenter repeated identical runs? Do other experimenters get the same readings as well?
-Is this proof for a cause-and-effect connection between a person’s thoughts and the plant’s purported reaction?
Backster demonstrated to a Yale group that a plant’s galvanometer response changes just before a spider scampers away from the researcher, and proclaimed “. . . each of the spider’s decisions to escape was being picked up by the plant, causing a reaction in the leaf.”
-Do spiders actually “decide” to escape just like humans consciously “decide” to act?
-Why would a plant respond to spider “thoughts” and not to the myriad decisions of the people in the room working the experiment?
When many researchers could not detect any galvanometer responses by plants, Backster “realized” that plants could be put into a faint by humans.
-Is this really evidence for this?
-Can we accept results as scientific if they only work for some people?
Backster measured the reactions of plants to his killing of brine shrimp in boiling water; they reacted “. . . in a ratio that was 5 to 1 against the possibility of chance.”
-Is 5-to-1 against the possibility of chance a “significant” indication that something didn't happen by chance?
. . . and so the book goes on and on reporting fabulous claims.
WATER DOUSING WITH WILLOW OR OTHER Y-SHAPED PLANT ROOTS OR BRANCHES
What community doesn’t have adherents to this claim–and they have their successful wells to prove it too! When a scientific rationale is suggested for “water witching,” it may often allude to the observation that willow and other trees roots do grow toward a source of water–everyone with an old septic tank has Roto-Rooter bills to prove that! Therefore, it is certainly “logical” that someone who is very sensitive should be able to sense this gentle “pull” of plant tissues toward water.
-People often think of water running in underground streams just like it does aboveground. But, except in special limestone areas where streams do actually erode underground channels, water usually exists spread out in a water table above layers of impervious rock, more like an underground lake than a stream. In most cases you would expect to hit water eventually on any drilling.
-Therefore, is hitting water a “proof” of “successful” witching if there are no additional drillings nearby as “controls?”
-What would happen to a nursery truck loaded with hundreds of willow saplings when it crossed a bridge over a river? (You may need to be careful when using such extended reasoning with students, so as not to appear sarcastic.)
BREEDING EXTINCT MAMMOTHS FROM FROZEN MAMMOTH EGG CELLS
In April 1984, Technology Review, published by MIT, revealed the exciting news that a Russian scientist had secured egg cells from a frozen mammoth in Siberia. Although this woolly relative of the elephant had been extinct for 10,000 years, the frozen DNA was alleged to be preserved sufficiently to allow, with some effort, fertilization by Asian elephant sperm and implantation into a surrogate mother elephant. This supposedly led to the birth of two hybrid calves which were described in detail. Since Technology Review is not a science fiction magazine, the story was picked up by newspapers from Chicago to Europe. The article submitted on April 1, 1984, (hint, hint) by an MIT biochemistry student was a “good-natured prank,” and its history is detailed in the spring, 1985, ISC Newsletter.
As with much pseudoscience, the sensational story travels far, the revelation that it was a prank does not. I still occasionally encounter colleagues who distantly heard about it and ask what became of the experiment.
A science teacher should be able to help students “smell a rat” here.
-It is difficult to verify the physical truth of such distant research, but in the time since 1985, a real discovery would have attracted the attention and visits of many researchers, along with a flurry of photos and headlines.
-While small cells and embryos can be fast-frozen and thawed, larger tissues form ice crystals from slow freezing that tear cell structures to ribbons. Could cell structures, including DNA molecules, survive a freeze, a thaw, and 10,000 years in between?
-Would there be the same number of chromosomes between the two species? Would the genes line up the same to permit a viable zygote? How close does the DNA of the two related species have to be to permit a hybrid?
The supreme end of education is expert discernment in all things–the power to tell the good from the bad, the genuine from the counterfeit, and to prefer the good and the genuine to the bad and the counterfeit.
-Samuel Johnson (1709-1784)
-A scientific name was purportedly given to the hybrid calves. That requires a published description. Where is it?
Acceptance of the story was undoubtedly greater because of the public's awareness of recent work in cloning various lower animals. And David Rorvik had published in 1978 In His Image: The Cloning of Man, another case of pseudoscience purporting to have actually produced clones of a wealthy patron. Rorvik eventually admitted the book was fictitious, but the cloning of people has become part of our “pop-sci” culture. By 1987, biologists confirmed in the June issue of Bioscience that “In mammals, there seems to be a unique and complementary contribution of male and female gametes . . . not true of other classes of animals.” That means that we cannot clone mammals; Rorvik's scenario was impossible with current technology. [2001 Editor’s note: Advances in technology allowed cloning, including “Dolly” the sheep about one decade after this issue.]
THE “HUNDREDTH MONKEY PHENOMENON”
In 1979, Lyell Watson authored the book Lifetide, which included several pages that reported on the transfer of a new learned behavior among troops of wild macaques on Japanese islands. In 1953, a female monkey discovered that sand and grit could be washed from sweet potatoes. This behavior was slowly learned by other members of the troop, and there is nothing unexpected or unusual in this process so far. But Watson goes ahead to contend that the anecdotal evidence indicates that by 1958, when one additional monkey learned the new technique, a “critical mass” was reached and a group consciousness was formed that resulted in monkeys spontaneously learning how to wash potatoes, not just on this island, but on other islands and the mainland, too.
The term “100th monkey” comes from Watson's framing the claim on a hypothetical example that 99 monkeys learned the normal way but when the hundredth one joined in this knowledge, a new collective consciousness was formed. This theme of “collective consciousness” has been picked up and promulgated by other authors for various purposes, greatly expanding the public’s awareness of this purported “scientific” finding. To a young generation brought up on Star Wars (“May the Force be with you.”), isn’t this evidence for a “group mind?”
-Amundson, in The Skeptical Inquirer Summer 1985, returns to the Japanese primatologists’ original reports and finds absolutely no evidence of anything but one-animal-to-another learning--the “group mind” was Watson's conclusions from observations that did not provide such evidence. Such intellectual footwork is very handy to teachers who aren't in the position to check original documents for every claim.
-Even without a researcher re-checking the original research, a class should be able to probe the implications of this claim. Has any student tapped into revelations about meiosis in class because a huge number of classmates across the U.S. are also studying it each fall? Or did their studying a lesson give someone else a mysterious insight?
The recent case of a moose wandering through Kansas, far from its normal range, is accepted because the wayward animal, distinctly recognizable as a moose, has been sporadically located by TV media who air footage of the critter and zoologists confirm “Yep, that is a moose.” However, are all reports of extirpated animals (the cougar, timber wolf, bear, etc.) to be taken as fact? The fact that they did at one time live here is offered as evidence that the climate and environment are appropriate or tolerable.
-How and why would an animal move from a distant area where it still exists to this location? Are there barriers, from natural rivers to killer highways?
-How many are required per unit area to form a breeding population?
-How long would a single individual last if there was no breeding population?
-Do any circuses come through here that might have lost an animal?
-How could the animal(s) survive in the midst of human populations without being caught, killed, or seen more often?
A retired U.S. Fish and Wildlife Service biologist R.L. Downing has noted that in Florida, several cougars are road-killed annually out of a total population of about 30, indicating that an area with much traffic but no road kills “. . . is unlikely to contain cougars” (ISC Newsletter Summer 1988). Such exercises in reasoning will help students address such sightings in a logical manner and distinguish between extensions of normal ranges, exotic or outlying cases, and unlikely reports.
The coelacanth was an ancient fish only known from fossils until specimens were fished out of deep ocean near Madagascar. The ivory-billed woodpecker was considered extinct until recent observations in Cuba. A rare bowerbird only known from three old museum specimens was recently found by an ornithologist. So, why can’t reports of other extinct animals perhaps be true, since they did exist at one time, and many wild areas are so remote? What about “Nessie” the Loch Ness monster as an aquatic dinosaur, Sasquatch as a surviving Neanderthal or Gigantopithecus, sea monsters as giant octopus or squid. And maybe the Thylacine or Tasmanian Wolf is still around?
Such reports are indeed the very grist for the mills of the ISC Newsletter where such claims are made in enough detail that students can again exercise some reasoning skills to separate the unlikely from the impossible.
TYPES OF EVIDENCE FOR ANIMALS
1. Actual specimen or substantial parts sufficient to provide an undisputed identification. Probably nothing less than this will be required for many claims, since it is possible for other forms of “evidence” below to be misidentified or even forged by individuals seeking publicity. There are cases of such forgeries based on contrived partial evidence but a whole critter that can be directly inspected is fairly conclusive evidence that one exists. That a specimen is not an aberrant form of something "normal" or that it represents a new species may require additional evidence, however.
2. Fecal analysis. Waste materials can be quite distinct for various animals but much is unresearched or undescribed and comparative material for extinct or unknown animals is usually not available.
3. Footprints, “tracks,” or scratch marks. Some fossil animals are described and known only from their tracks in ancient mud. But deducing the animal that made the tracks is an uncertain task with many assumptions. The Paluxy Creek report of man footprints alongside dinosaurs tracks revealed under additional examination, that the “human” prints belonged to a small dinosaur with claws! The marks made by the giant squid on sperm whales are prints left on living tissue. Because the whale continues to grow, the size of the sucker marks on the whale cannot be used to infer the size of giant squid (“The Giant Squid” Sci. Amer. April 1982 Reprint No. 1515).
4. Sound recordings and sonar. The range of the prairie mole cricket in Kansas, as well as the rediscovery of tropical birds presumed extinct, is often made on the basis of hearing their songs. Because aberrant calls are possible, it may not provide the conclusive evidence for an animal’s existence that scientists would prefer. And when a sonar sweep was made across the Loch Ness, failure to find anything did not provide the absolute disproof that some would require, either.
5. Bones. The Piltdown forgery went undetected for some time, but today's dating techniques and larger collections of vertebrate skeletons for comparison make bones better evidence. The legendary “onza,” an animal varying from the standard mountain lion or cougar, did not gain acceptance based on one skeleton. However, the killing and preserving of a whole specimen (ISC Newsletter Vol. 4 No. 4, Vol. 5 No. 1) may confirm its identity.
6. Photographs. Oftentimes there are problems with scale and interpretation even when the photos are submitted by witnesses in good faith. And of course the technology to “fake” photos has advanced.
7. Tissue analysis. The new biochemical techniques are allowing fish and game officers to analyze and identify the meat of endangered species for illegal import cases, and may have growing use in cryptozoology. However, these techniques usually require comparison tissues, tissues that are not available for extinct or unknown animals.
8. Eyewitness reports. The only “substance” of most National Enquirer articles, the eyewitness report, is rarely evidenced when it stands alone. For example, several ornithologists reported seeing birds “anting,” a strange behavior where birds pick up formic acid ants in their beaks and probe through their feathers. The process fumigates for lice, but was not accepted until more eyewitness accounts and photos were available.
Pseudoscience is not always a bothersome static that gets in the way of our conveying “proper” science facts. It provides some excellent opportunities for students to develop rigor in thinking, gain an appreciation for that middle ground where we don't yet know, and see the tolerance limits to human knowledge. Indeed, I think it would be difficult (and less exciting) to teach these mental gymnastics if all our students came to us with absolute reliance on the current dogma and no misconceptions, myths, or pseudoscience for us to work from. What is disturbing is that so many graduate with no reduction in such fuzzy thinking, and that acceptance of misconceptions, myths, and pseudoscience in the U.S. is rampant and increasing.
A conscious effort has been made in compiling this issue of the Kansas School Naturalist to avoid offering any short-cut formula or easy answers for a teacher to use in countering pseudoscience in the classroom.
Some sensational claims gain acceptance because they rely on a little knowledge of current science breakthroughs (i.e. the mammoth-elephant hybrids from frozen eggs in an era of in vitro fertilization and cloning). Such cases illustrate how “a little science understanding can be dangerous.” The solution is more understanding and more practice in reasoning. There simply is no effective substitute for knowing absolutely all of the science you can possibly learn and applying your greatest powers of reason. The more practice students can gain examining the real world and engaging in intelligent discussion, the more likely they are to develop an attitude that will help them solve problems throughout their lives. This “scientific” attitude is an excellent way of life, whether they enter a science career or not.

SOURCES FOR PRACTICE RECOGNIZING SCIENCE AND PSEUDOSCIENCE
The only way to insure that students will develop skills recognizing weak claims to science is to challenge students to make such distinctions in classwork. While the National Enquirer and other tabloids provide a constant stream of near-nonsense, you may want students to bite off more difficult issues. The following two publications will provide a year's supply of puzzling intermediate cases:
The ISC Newsletter appears four times a year, is published by the International Society of Cryptozoology and is available for $30 annually. The organization also publishes the journal Cryptozoology although the newsletter will be of greater use to the classroom teacher. In biology circles, this is a controversial publication, covering a range of items from bonafide discoveries of organisms thought extinct to musings over Sasquatch evidence.
Science Frontiers is published by William Corliss who specializes in extracting notes on anomalies that appear in bonafide science journals. This bimonthly newsletter is $5 for six issues or free with a book purchase. Corliss operates “The Sourcebook Project” that brings together reports on everything from ball lightning to Marfa lights . . . some of which are now understood in science, some outside science paradigms, and much yet to be confirmed and understood. Order from: The Sourcebook Project, P.O. Box 107, Glen Arm, MD 21057.
Finally, the following publication concentrates on exposing claims of the paranormal and occasionally enters into arguments with The ISC Newsletter:
The Skeptical Inquirer is published by the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP) and provides an excellent critique of nearly all pseudoscience issues (ESP. UFO's, face on Mars, etc.). It is the best antidote for National Enquirer available. Four issues per year cost $22.50,. $39 for two years and $54 for a three year subscription from: Skeptical Inquirer, Box 229, Buffalo, New York 14215.
