* ''']''' is an approach to evolutionary models of cultural information transfer based on the concept that units of information, or "memes", have an independent existence, are self-replicating, and are subject to selective evolution through environmental forces.<ref name=Polichak/> Starting from a proposition put forward in the writings of Richard Dawkins, it has since turned into a new area of study, one that looks at the self-replicating units of culture.

Revision as of 21:18, 29 July 2009

This is a list of topics characterized as pseudoscience by organizations within the international scientific community, by notable skeptical organizations, or by notable academics or researchers. Besides explicitly using the word "pseudoscience", some may also have used synonyms that help to explain why they consider a topic to be pseudoscientific. The existence of such expressed opinions suffices for inclusion in this list, and therefore inclusion does not necessarily indicate that any given entry is in fact pseudoscience. Opposing points of view exist and are presented in the main article for each subject listed below. Also included are important concepts associated with the main entries, and concepts that, while notable and self-evidently pseudoscientific, have not elicited commentary from mainstream scientific bodies or skeptical organizations. Notable parodies of pseudoscientific concepts are also included.

Some subjects in this list may be questioned aspects of otherwise legitimate fields of research, or have legitimate ongoing scientific research associated with them. For instance, while some proposed explanations for hypnosis have been criticized for being pseudoscientific, the phenomenon is generally accepted as real and scientific explanations exist. Some subjects and methods are included because certain claims regarding them are pseudoscientific, even though the subjects themselves may be legitimate, or the methods themselves may have some efficacy, thus indicating it is the claims that are pseudoscientific, and not necessarily the subjects or methods.

Astronomy and space sciences

  • Astrology refers to any of several systems of understanding, interpreting and organizing knowledge about reality and human existence, based on the relative positions and movement of various real and construed celestial bodies.
  • Dogon people and Sirius B is a series of claims that the Dogon tribe knew about the white dwarf companion of Sirius despite it being invisible to the naked eye.
  • Erich Von Däniken proposed that Earth was visited by ancient astronauts. Such beings have been claimed to have initiated the rise of human civilization or provided significant technological assistance to various ancient civilizations.
  • The Face on Mars (in Cydonia Mensae) is a rock formation on Mars asserted to be evidence of intelligent, native life on the planet. High resolution images taken recently show it to appear less face-like. It features prominently in the work of Richard C. Hoagland.
  • Nibiru collision is a prediction first made by contactee Nancy Lieder that a mythological planet Nibiru would collide with Earth. After adjusting her prediction many times, she now claims the year of the occurrence to be 2012.

Earth and Earth sciences

Paranormal and Ufology

Paranormal subjects have been subject to critiques from a wide range of sources including the following claims of paranormal significance:

  • Animal mutilations are cases of animals, primarily domestic livestock, with seemingly inexplicable wounds. These wounds have been said to be caused by natural predation, extra terrestrials, cults, or covert government organizations.
  • Channeling is the communication of information to or through a person allegedly from a spirit or other paranormal entity.
  • Crop circles are geometric designs of crushed or knocked-over crops created in a field. Aside from skilled farmers or pranksters working through the night, explanations for their formation include UFOs and anomalous, tornado-like air currents. The study of crop circles has become known as "cerealogy".
  • Cryptozoology is the search for creatures that are considered not to exist by most biologists. Well known examples of creatures of interest to cryptozoologists include Bigfoot, Yeti, and the Loch Ness Monster. According to leading skeptical authors Michael Shermer and Pat Linse, "Cryptozoology ranges from pseudoscientific to useful and interesting, depending on how it is practiced."
  • Dowsing refers to practices said to enable one to detect hidden water, metals, gemstones or other objects.
  • Levitation, in this sense, is the act of rising up from the ground without any physical aids, usually by the power of thought.
  • Materialization is the supposed creation or appearance of matter from unknown sources.
  • Pseudoarchaeology is the investigation of the ancient past using alleged paranormal or other means which have not been validated by mainstream science.
  • Psychic surgery is a type of medical fraud, popular in Brazil and the Philippines. Practitioners use sleight of hand to make it appear as though they are reaching into a patients body and extracting "tumours".
  • Psychokinesis is the paranormal ability of the mind to influence matter or energy at a distance.
  • Séances are ritualized attempts to communicate with the dead.
  • Tutankhamun's curse was allegedly placed on the discoverers of Egyptian pharaoh Tutankhamun's tomb, causing widespread deaths and other disastrous events.
    • Close encounters are events where persons witness UFOs, or purportedly meet and/or communicate with alien beings.

Psychology

The neutrality of this section is disputed. Relevant discussion may be found on the talk page. Please do not remove this message until conditions to do so are met. (April 2009) (Learn how and when to remove this message)
  • Attachment therapy is the common name for a set of potentially fatal clinical interventions and parenting techniques aimed at controlling aggressive, disobedient, or unaffectionate children using "restraint and physical and psychological abuse to seek their desired results." (The term "attachment therapy" may sometimes be used loosely to refer to mainstream approaches based on attachment theory, usually outside the USA where pseudoscientific form of attachment therapy is less known). Probably the most common form is holding therapy in which the child is restrained by adults for the purpose of supposed cathartic release of suppressed rage and regression. Perhaps the most extreme, but much less common, is "rebirthing," in which the child is wrapped tightly in a blanket and then made to simulate emergence from a birth canal. This is done by encouraging the child to struggle and pushing and squeezing him/her to mimic contractions. Despite its name it is not based on attachment theory or research. In 2006 it was the subject of an almost entirely critical Taskforce Report commissioned by the American Professional Society on the Abuse of Children (APSAC). Not all forms of attachment therapy are coercive and since the Candace Newmaker case there has been a move towards less coercive practices by leaders in the field.
  • Biological psychiatry is an approach to psychiatry that aims to understand mental disorder in terms of the biological function of the nervous system. Psychiatrists Colin A. Ross and Alvin Pam argue that 'the legitimacy and cultural authority granted to an objective and value-free science is undeserved by biologic psychiatry' and that 'the valid notion of investigating constitutional determinants of psychological disorders has been coopted by a biomedical reductionist ideology.' Such sentiments and conflicting results of scientific research have spawned the Biopsychiatry controversy and ADHD controversy.
  • Graphology is a psychological test based on a belief that personality traits unconsciously and consistently influence handwriting morphology - that certain types of people exhibit certain quirks of the pen. Analysis of handwriting attributes provides no better than chance correspondence with personality, and neuroscientist Barry Beyerstein likened the assigned correlations to sympathetic magic. Graphology is only superficially related to forensic document examination, which also examines handwriting.
  • Memetics is an approach to evolutionary models of cultural information transfer based on the concept that units of information, or "memes", have an independent existence, are self-replicating, and are subject to selective evolution through environmental forces. Starting from a proposition put forward in the writings of Richard Dawkins, it has since turned into a new area of study, one that looks at the self-replicating units of culture. It has been proposed that just as memes are analogous to genes, memetics is analogous to genetics. Memetics has been deemed a pseudoscience on several fronts. Its proponents' assertions have been labeled "untested, unsupported or incorrect" and it has been called redundant, without physical basis, and a means for attacking others' beliefs as opposed to actual science

Health and medicine

  • Alternative medicine has been described as pseudoscientific. The National Science Foundation has conducted surveys of the "Public Attitudes and Public Understanding" of "Science Fiction and Pseudoscience", which includes studying the popularity of alternative medicine. It considers belief in alternative medicine a matter of concern, defining it as "all treatments that have not been proven effective using scientific methods." After quoting the Committee for Skeptical Inquiry's listing of alternative medicine as one of many pseudoscientific subjects, as well as mentioning the concerns of individual scientists, organizations, and members of the science policymaking community, it comments that "nevertheless, the popularity of alternative medicine appears to be increasing." "At least 60 percent of U.S. medical schools devote classroom time to the teaching of alternative therapies, generating controversy within the scientific community." It has been reported that universities are "increasingly turning their backs on homoeopathy and complementary medicine amid opposition from the scientific community to “pseudo-science” degrees." Degrees in alternative medicine have been described as "'pseudo-science' degrees", "anti-scientific", and "harmful".
  • Anthroposophic medicine, or Anthroposophically extended medicine, is a school of complementary medicine founded in the 1920s by Rudolf Steiner in conjunction with Ita Wegman based on the spiritual philosophy of anthroposophy. It is an individualized holistic and salutogenic approach to health, deemphasizing randomized controlled trials. Medications are formulated to stimulate healing by matching "key dynamic forces" with symptoms, and are prepared for external, oral, or parenteral introduction in various dilutions ranging from whole to homeopathic. The use of vaccinations, antibiotics, and antipyretics is generally restricted or delayed. Skeptic Robert Carroll likens to sympathetic magic the principle that curative plants may be identified by distortions or abnormalities in their morphology or physiology. Carroll and others state that the system is not based in science. No thorough scientific analysis of the efficacy of anthroposophical medicine as a system independent of its philosophical underpinnings has been undertaken; no evidence-based conclusion of the overall efficacy of the system can be made at this time.
  • The Bates method for better eyesight is an educational method developed by ophthalmologist William Bates intended to improve vision "naturally" to the point at which it can allegedly eliminate the need for glasses by undoing a habitual strain to see. In 1929 Bates was cited by the FTC for false or misleading advertising in connection with his book describing the method, Perfect Sight Without Glasses, though the complaint was later dismissed. Although some people claim to have improved their eyesight by following his principles, Bates' ideas about vision and accommodation have been rejected by mainstream ophthalmology and optometry.
  • Biorhythms – a hypothesis holding that human physiology and behavior are governed by physical, emotional, and intellectual cycles lasting 23, 28, and 33 days, respectively. The system posits that, for instance, errors in judgment are more probable on days when an individual's intellectual cycle, as determined by days since birth, is near a minimum. No biophysical mechanism of action has been discovered, and the predictive power of biorhythms charts is no better than chance. For the scientific study of biological cycles such as circadian rhythms, see chronobiology.
  • Brain Gym – a commercial training program that claims that any learning challenges can be overcome by finding the right movements, to subsequently create new pathways in the brain. They claim that the repetition of the 26 Brain Gym movements "activates the brain for optimal storage and retrieval of information", and are designed to "integrate body and mind" in order to improve "concentration, memory, reading, writing, organizing, listening, physical coordination, and more." Its theoretical foundation has been thoroughly discredited by the scientific community, who describe it as pseudoscience. Peer reviewed scientific studies into Brain Gym have found no significant improvement in general academic skills. Its claimed results have been put down to the placebo effect and the benefits of breaks and exercise. Its founder, Paul Dennison, has admitted that many of Brain Gym's claims are not based on good science, but on his "hunches".
  • Chiropractic is an alternative medicine practice focusing on spinal manipulation. Many modern chiropractors target solely mechanical dysfunction, and offer health and lifestyle counseling. Many others, however, base their practice on the vitalism of D.D. Palmer and B. J. Palmer, maintaining that all or many organic diseases are the result of hypothetical spinal dysfunctions known as vertebral subluxations and the impaired flow of Innate intelligence, a form of putative energy. These ideas are not based in science, and along with the lack of a strong research base are in part responsible for the historical conflict between chiropractic and mainstream medicine. Recent systematic reviews indicate the possibility of moderate effectiveness for spinal manipulation in the management of nonspecific low back pain. The effectiveness of chiropractic spinal manipulation has not been demonstrated according to the principles of evidence-based medicine for any other condition. Adverse events with possible neurologic involvement following spinal manipulation, particularly upper spinal manipulation, occur with a frequency of between 33% and 61%. Most events are minor, such as fainting, dizziness, light headedness, headache, or numbness or tingling in the upper limbs; serious complications such as subarachnoid hemorrhage, vertebral artery dissection, or myelopathy are observed infrequently.
  • Applied Kinesiology (AK) is a chiropractic diagnostic method using manual muscle-strength testing for medical diagnosis and a subsequent determination of prescribed therapy, which proponents believe can identify health problems or nutritional deficiencies through practitioner assessment of external physical qualities such as muscle response, posture, or motion analysis. A variety of therapies are prescribed based on tested weakness or smoothness of muscle action and a conjectured viscerosomatic association between particular muscles and organs. For example, a practitioner will give the patient a jar containing a substance to hold in one hand, then test for muscle strength in the other hand; if there is little resistance, the practitioner may conclude that the patient is allergic to that substance. The sole use of Applied Kinesiology to diagnose or treat any allergy or illness is not scientifically supported, and the International College of Applied Kinesiology requires concurrent use of standard diagnostic techniques. Applied kinesiologists are often chiropractors, but may also be naturopaths, physicians, dentists, nutritionists, physical therapists, massage therapists, and nurses. Applied Kinesiology should not be confused with kinesiology, the scientific study of human movement.
  • Innate Intelligence is a form of putative energy, the flow of which is considered by some Chiropractors to be responsible for patient health. Chiropractic historian Joseph C. Keating, Jr., PhD. stated: "So long as we propound the 'One cause, one cure' rhetoric of Innate, we should expect to be met by ridicule from the wider health science community. Chiropractors can’t have it both ways. Our theories cannot be both dogmatically held vitalistic constructs and be scientific at the same time. The purposiveness, consciousness and rigidity of the Palmers’ Innate should be rejected."
  • Vertebral subluxation is a uniquely Chiropractic term. It describes variously a site of impaired flow of innate or a spinal lesion resulting in neuromusculoskeletal or visceral dysfunction. Scientific consensus does not support the existence of chiropractic's vertebral subluxation.
  • Crystal healing is the belief that crystals have healing properties. Once common among pre-scientific and indigenous peoples, it has recently enjoyed a resurgence in popularity with the new age movement.
  • Electromagnetic Hypersensitivity (EHS) is a reported sensitivity to electric and magnetic fields or electromagnetic radiation of various frequencies at exposure levels well below established safety standards. Symptoms are inconsistent, but can include headache, fatigue, difficulty sleeping, and similar non-specific indications. Provocation studies find that the discomfort of sufferers is unrelated to hidden sources of radiation, and "no scientific basis currently exists for a connection between EHS and exposure to ."
  • Homeopathy is the belief in giving a patient with symptoms of an illness extremely dilute remedies that are thought to produce those same symptoms in healthy people. These preparations are often diluted beyond the point where any treatment molecule is likely to remain. Studies of homeopathic practice have been largely negative or inconclusive. No scientific basis for homeopathic principles has been substantiated.
  • Magnetic therapy is the practice of using magnetic fields to positively influence health. While there are legitimate medical uses for magnets and magnetic fields, the field strength used in magnetic therapy is too low to effect any biological change, and the methods used have no scientific validity.
  • Radionics is a means of medical diagnosis and therapy which proponents believe can diagnose and remedy health problems using various frequencies in a putative energy field coupled to the practitioner's electronic device. The first such "black box" devices were designed and promoted by Albert Abrams, and were definitively proven useless by an independent investigation commissioned by Scientific American in 1924. The internal circuitry of radionics devices is often obfuscated and irrelevant, leading proponents to conjecture dowsing and ESP as operating principles. Similar devices continue to be marketed under various names, though none is approved by the US Food and Drug Administration; there is no scientific evidence for the efficacy or underlying premise of radionics devices. The radionics of Albert Abrams and his intellectual descendants should not be confused with similarly named reputable and legitimate companies, products, or medical treatments such as radiotherapy or radiofrequency ablation.
  • Urine therapy. Drinking either one's own undiluted urine or homeopathic potions of urine for treatment of a wide variety of diseases is based on pseudoscience.
  • Vitalism is a doctrine that the processes of life are not explicable by the laws of physics and chemistry alone and that life is in some part self-determining. According to the Encyclopedia of Pseudoscience, "today, vitalism is one of the ideas that form the basis for many pseudoscientific health systems that claim that illnesses are caused by a disturbance or imbalance of the body's vital force." "Vitalists claim to be scientific, but in fact they reject the scientific method with its basic postulates of cause and effect and of provability. They often regard subjective experience to be more valid than objective material reality."

Religious and spiritual beliefs

Spiritual and religious practices and beliefs are normally not classified as pseudoscience. The following have been related to pseudoscience in some way, however:

  • Creationist cosmologies are ones which, among other things, allow for a universe that is only thousands of years old.
  • Flood geology is the creationist form of geology that advocates most of the geologic features on Earth are explainable by a global flood.
  • Modern geocentrism, citing uniform gamma-ray bursts distribution, and other arguments of this type, as evidence that we are at the center of the universe.
  • Intelligent design maintains that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." These features include:
  • Irreducible complexity is the claim that some systems are so complex that they cannot have evolved from simpler systems. It is used by proponents of intelligent design to argue that evolution by natural selection alone is incomplete or flawed, and that some additional mechanism (an "Intelligent Designer") is required to explain the origins of life.
  • Specified complexity is the claim that when something is simultaneously complex and specified, one can infer that it was produced by an intelligent cause (i.e., that it was designed) rather than being the result of natural processes.
  • The Shroud of Turin is a length of linen cloth believed by some members of the Christian community to have been Jesus' death shroud. Radiocarbon dating of the original material has shown that it dates from the 13th or 14th century, though some claim that the material tested was not representative of the whole shroud. Analyses of the paint and the herringbone twill weave of the cloth similarly point to a medieval origin.

Energy

  • Hongcheng Magic Liquid is a pseudoscience incident in China where an inventor claimed that could turn water into a usable fuel by just adding a few drops of his "secret formula" liquid. The government of China and the Chinese Communist Party were alarmed by pseudoscience developments like this one and issued a joint proclamation condemning the recent decline of public education in science.
  • Perpetual motion is a class of proposed machines that violate one of the Laws of Thermodynamics. Perpetual motion has been recognized as extrascientific since the late 18th century, but proposals and patents for such devices continue to be made to the present day.
  • Water-fuelled cars are an instance of perpetual motion machines. Such devices are claimed to use water as fuel or produce fuel from water onboard with no other energy input.

Other

  • Laundry balls are spherical or toroidal objects marketed as soap substitutes for washing machines.
  • Scientific racism is the claim that scientific evidence shows the inferiority or superiority of certain races.
  • Melanin Theory is a belief founded in the distortion of known physical properties of melanin, a natural polymer, that posits the inherent superiority of Black people and the essential inhumanity and an inferiority of Whites.

Idiosyncratic ideas

The following concepts have only a very small number of proponents, yet have become notable.

  • Bogdanov Affair was an academic dispute regarding the legitimacy of a series of theoretical physics papers written by French twin brothers Igor and Grichka Bogdanov.
  • Penta Water is a claimed acoustically-induced structural reorganization of liquid water into long-lived small clusters of five molecules each. Neither these clusters nor their asserted benefits to humans have been shown to exist.

Previously disputed natural phenomena

Certain natural phenomena were previously considered pseudoscientific (because of the difficulty in obtaining evidence to prove their existence and real origins), but now are no longer doubted by modern science:

  • Ball lightning is a slow-moving, luminous sphere which is up to 30 cm in diameter, explanations for which have ranged from combusted hydrocarbon gas to "Will o' the wisp" creatures. The phenomenon is now better understood and contemporary scientific consensus clearly accepts the existence of a phenomenon which mimics some reports of ball lightning, but is on a much smaller scale.
  • Meteorites are objects composed of stone and/or metal that fall from space onto the surface of the Earth. This was contested by skeptical scientists in the 18th century, especially those of the French Academy. Ernst Chladni demonstrated their celestial origin in 1794, and a substantial fall of meteorites in France in 1803 dispersed the skepticism.
  • Continental drift is a theory which suggests the major continents of the Earth move into different positions over geological time. This was long considered to be pseudoscience. It was later recognized as a solid theory when more evidence of the existence of Pangea appeared and when abundant evidence for sea floor spreading and subduction was discovered during the 1950s and 60s. The concept was replaced with plate tectonics.

Parody pseudoscience

The following are notable parodies of other pseudosciences and pseudoscientific concepts, or scientific jokes posing as serious theories.

  • Dihydrogen monoxide hoax A web site (dhmo.org) purports to be the work of concerned citizens, to examine "the controversy surrounding dihydrogen monoxide," including evidence of its environmental, health, and other threats. Dihydrogen Monoxide (H2O) is also known as water.
  • Turboencabulator is a hoax invention that relies on technobabble and incongruous use of jargon to give the appearance of a legitimate invention when it is, in fact, nonsense.

Pseudoscience in popular culture

The Endochronic Properties of Resublimated Thiotimoline is a science fiction short story by Isaac Asimov that is a spoof scientific paper first published in the December 1953 Astounding Science Fiction that describes the chemical compound thiotimoline, which is notable for the fact that when it is mixed with water, the chemical actually begins to break down before it contacts the water. This is explained by the fact that in the thiotimoline molecule, there is at least one carbon atom such that, while two of the carbon's four chemical bonds lie in normal space and time, one of the bonds projects into the future and another into the past.
Pâté de Foie Gras is a science fiction short story by Isaac Asimov which was first published in the September 1956 issue of Astounding Science Fiction about the discovery on a farm in Texas of a mutant goose that is able to lay golden eggs because it has a liver capable of producing nuclear reactions.
