Wikipedia:WikiProject Skepticism/List of questionable claims

1. This list is about skepticism as well as its association with criticisms, which is the reason for the inclusion of some topics about criticisms. The two topics are intimately related. The characteristics of scientific skepticism utilizes critical thinking in evaluating claims to reach a well-justified conclusion or logical answer, and attempts to oppose claims made which lack suitable evidential basis. Like a scientist, a scientific skeptic aims to decide claims based on verifiability and falsifiability rather than accepting claims on faith, anecdotes, or relying on unfalsifiable categories. Skeptics often focus their criticism on claims they consider to be implausible, dubious or clearly contradictory to generally accepted science. The term pseudoskepticism is often used by the opponents of skepticism as a way of summarizing their critique.

2. Some items are included simply because there has been debate from skeptical critics that have characterized it as its possible involvement of being or having a relationship to criticism, regardless of whether it was or was not. Other items are included as educational aids, as an understanding of these subjects, to enable one to better understand the subject of skeptical topics, and hopefully, making the whole process of scientific skepticism much more transparent.

3. Therefore, inclusion here is definitely not a statement that the subject matter is skeptical, that solely it has aspects regarded as rational skepticism by certain groups or people. It is only listed here because scientific skeptics, debunkers, consumer protection advocates, and/or government officials (FDA, FTC, etc.) consider the subject to be in some manner related to the subject of skepticism or criticisms, and therefore of possible value when researching the subject.The Skeptics Dictionary: Definition of Quackery [http://www.skepdic.com/quackery.html Article]QuackWatch: Quackery Definition [http://www.quackwatch.org/01QuackeryRelatedTopics/quackdef.html Article]Quackery Information on Healthline [http://www.healthline.com/galecontent/quackery Article]Federal Trade Commission.

• Chiropractic Chiropractic is a popular form of alternative medicine whose physical mode of action is spinal manipulations that allegedly unblock nerve signals sent by the brain so that the body can heal itself. This care involves the adjustment of the spine and joints to influence the body’s nervous system and natural defense mechanisms to alleviate pain and improve general health. It is primarily used to treat back problems, headaches, nerve inflammation, muscle spasms, and other injuries and traumas.Critical thinking by Dr. Christopher Kent [http://www.worldchiropracticalliance.org/tcj/1996/may/may1996kent.htm Article]Creating Chiropractic Community

• Crystal power Crystal power, also known as crystal healing, is the belief that crystals have healing, mystical and/or paranormal powers. This belief has been part of several indigenous cultures for centuries.

• Folk medicine Folk medicine refers collectively to procedures traditionally used for treatment of illness and injury, aid to childbirth, and maintenance of wellness. It is a body of knowledge distinct from "scientific medicine" and may coexist in the same culture. It is usually unwritten and transmitted orally until someone "collects" it. Folk medicine is sometimes associated with quackery when practiced as theatrics or otherwise practiced fraudulently, and sometimes with witchcraft and often with shamanism, yet it may also preserve important knowledge and cultural tradition from the past.[http://www.cancer.org/docroot/ETO/content/ETO_5_3X_Shamanism.asp?sitearea=ETO ACS :: Shamanism][http://www.ucs.mun.ca/~zharuna/folkbeliefs1.html Folk Belief and Folk Medicine][http://www.wvculture.org/history/wvhs1041.html Folk Medicine]

• Herbalism Herbalism, also known as herbal medicine, herbal therapy, herbology, and phytotherapy, is a folk and traditional medicinal practice based on the use of plants and plant extracts.

• Homeopathy Homeopathy holds the premise of treating the sick with extremely diluted agents that, in undiluted doses, produce similar symptoms in the healthy. Its adherents and practitioners assert that the therapeutic potency of a remedy can be increased by serial dilution of the drug, combined with succussion, or vigorous shaking. Critics describe it as pseudoscience[http://www.skeptics.org.uk/article.php?dir=articles&article=homeopathy.php Homeopathy] at UK-Skeptics and quackery.[http://www.ncahf.org/pp/homeop.html NCAHF Position Paper on Homeopathy] National Council Against Health Fraud The theory that extreme dilution makes drugs more powerful is inconsistent with the laws of chemistry and physics.[http://homeopathyhome.com/reference/organon/63.html#269 Christian Friedrich Samuel Hahnemann's "Organon Of Medicine" translated by Dudgeon Fifth Edition § 269] Placebo-controlled clinical trials have given mixed results, but most have methodological problems, with better-quality trials more likely to give negative results.{{cite journal |vauthors=Shang A, Huwiler-Muntener K, Nartey L, Juni P, Dorig S, Sterne JA, Pewsner D, Egger M | title=Are the clinical effects of homoeopathy placebo effects?

• Innate intelligence It is well known that the use of the "innate intelligence" concept is controversial within the chiropractic profession, and is seen by many in the profession as antiquated metaphysical jargon which has no reference to reality. It is also a part of the "straight" vs. "mixing" battle that has been going on since the inception of chiropractic. Lon Morgan, DC, a reform chiropractor, expressed his criticism in this way: "Innate Intelligence clearly has its origins in borrowed mystical and occult practices of a bygone era. It remains untestable and unverifiable and has an unacceptably high penalty/benefit ratio for the chiropractic profession. The chiropractic concept of Innate Intelligence is an anachronistic holdover from a time when insufficient scientific understanding existed to explain human physiological processes. It is clearly religious in nature and must be considered harmful to normal scientific activity."http://www.jcca-online.org/Client/cca/jcca.nsf/Articles/52C805D03B6EAB9F852569B40059418F?OpenDocument
• Iridology Iridology, also known as iridodiagnosisCline D; Hofstetter HW; Griffin JR. Dictionary of Visual Science. 4th ed. Butterworth-Heinemann, Boston 1997. {{ISBN|0-7506-9895-0}}, is an alternative medicine practice in which patterns, colors, and other characteristics of the iris are examined for information about a patient's systemic health. Practitioners match their observations to iris charts which divide the iris into zones that correpsond to specific parts of the human body. The eye, therefore, acts as a "window" into the body's state of health, although Iridology is a practice that is not recognized by mainstream medicine. Critics, mostly practitioners of mainstream medicine, dismiss iridology largely because published studies have indicated a lack of success for its claims.{{cite journal | pmid=480560 | date=1979 | last1=Simon | first1=A. | last2=Worthen | first2=D.

• Vertebral subluxation remains unsubstantiated and largely untested, and a debate about whether to keep it in the chiropractic paradigm has been ongoing for decades.

• Aura (paranormal) In New Age belief, Aura refers to the energy field emanating from the surface of a person or object. This emanation is visualized as an outline of cascading color and may be held to represent soul vibrations, chakric emergence, or a reflection of surrounding energy fields. There is no scientific evidence for the existence of auras.[http://skepdic.com/auras.html Auras in the "Skeptic's dictionary"]

• Conspiracy theory A conspiracy theory attempts to explain the ultimate cause of an event or chain of events (usually political, social, or historical events) as a secret, and often deceptive, plot by a covert alliance of powerful or influential people or organizations. Many conspiracy theories claim that major events in history have been dominated by conspirators who manipulate political happenings from behind the scenes. The term "conspiracy theory" is used by mainstream scholars and in popular culture to identify a type of folklore similar to an urban legend, especially an explanatory narrative which is constructed with methodological flaws.Johnson, 1983 The term is also used pejoratively to dismiss claims that are alleged by critics to be misconceived, paranoid, unfounded, outlandish, irrational, or otherwise unworthy of serious consideration. For example, "Conspiracy nut" and "conspiracy theorist" are used as pejorative terms. Some whose theories or speculations are labeled a "conspiracy theory" reject the term as prejudicial.
• Coral calcium Coral Calcium is a salt of calcium derived from fossilized coral reefs. There have been many unsubstantiated claims made regarding coral calcium, perhaps the most controversial of which is that taking coral calcium can cure cancer by increasing "body pH." The FDA has prohibited disease treatments cures in advertising. Additionally, it can be dangerous for people with certain medical conditions (such as kidney failure) to take excess coral calcium.[http://www.quackwatch.org/01QuackeryRelatedTopics/DSH/coral.html Quackwatch article warning about dubious claims for coral calcium][http://www.ftc.gov/opa/2003/06/trudeau.htm Marketers of coral calcium product are prohibited from making disease treatment and cure claims in advertising.] - FTC news release, Jan 22, 2004[http://www.CoralCalciumGuide.com Coral Calcium] - Reference Guide[http://www.quackwatch.org/01QuackeryRelatedTopics/DSH/coral2.html Acid/Alkaline Theory of Disease Is Nonsense] - Gabe Mirkin, M.D.[http://www.time.com/time/columnist/jaroff/article/0,9565,433084,00.html Coral Calcium: A Barefoot Scam] - Leon Jaroff, Time magazine article
• Creation-evolution controversy The creation-evolution controversy (also termed the creation vs. evolution debate or the origins debate) is a recurring dispute about the origins of the Earth, humanity, life, and the universe, a debate most prevalent in certain regions of the United States, where the mass media often portrays it as part of the culture wars or a supposed dispute between religion and science. The debate concerns what should be taught as science in schools. The creationists argue that both creationism and evolution are beliefs, and should be given equal weight in science classes. Leaders of the large established churches and the scientific community maintain that creationism is not science, and therefore has no place in a science class.[http://news.bbc.co.uk/2/hi/uk_news/education/4828238.stm BBC Article]
• Crop circles Crop circles are geometrical formations of flattened crops found in England and elsewhere. They have been found in wheat, barley, canola, rye, corn, linseed and soy.

• Dental amalgam controversy‎ Controversy exists regarding the use of mercury in dentistry, in dental fillings. A minority of dentists has always been opposed to amalgam use but evidence of adverse effects on patients from mercury in amalgam fillings is contradictory and there remains no conclusive evidence of measurable ill-effects despite the fact that amalgam has been in use for over 150 years and continues to be the most common material used in fillings. Overall, however, its use is declining due to improving dental health generally and increasing availability of new alternatives.

• Dermo-optical perception Dermo-optical perception (DOP) refers to the supposed ability to see without using the eyes (as distinct from blindsight). Typically, people who claim to have dermo-optical perception claim to be able to see using the skin of their fingers or hands. People who claim to have DOP often demonstrate it by reading while blindfolded. Dermo-optical perception is sometimes referred to as bio-introscopy. DOP has been discredited as pseudoscience, and explainable by the use of magicians' tricks.[http://skepdic.com/dop.html Skeptic's Dictionary entry on Dermo-optical perception][http://www.randi.org/encyclopedia/dermo-optical%20perception.html Randi Institute on Dermo-optical perception]

• Ear candling Ear candling, also called ear coning, is a folk medicine practice intended to remove earwax (cerumen) and "toxins" from a person's ear by means of a hollow candle placed in the ear. It involves placing one end of a hollow candle in the ear canal and lighting the other end. Proponents maintain the resulting vacuum can clean out the ear, but mainstream medical science discounts this theory due to lack of evidence supporting it.{{cite journal | url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=8849790&dopt=Abstract | pmid=9790 | date=1976 | last1=Fuller | first1=R.

• Global warming controversy The global warming controversy primarily concerns what steps society should take in response to global warming, and whether it is in a country's economic interest to take action to reduce emissions of greenhouse gases. There is a strong consensus among scientists that recent warming is caused by anthropogenic emissions of greenhouse gases, and that warming will continue with serious consequences if emissions continue; only a few scientists disagree. Most of those skeptical scientists who disagree are not climate specialists such as a climatologist and some of them have been funded by ExxonMobil to create uncertainty.Scientists' Report Documents ExxonMobil's Tobacco-like Disinformation Campaign on Global Warming Science [http://www.ucsusa.org/news/press_release/ExxonMobil-GlobalWarming-tobacco.html Report] Outside the scientific community, there is a greater amount of opposition to these conclusions from some corporations, advocacy groups, politicians, and individuals (see global warming skeptics).
• Grapefruit seed extract Grapefruit seed extract (GSE), also known as citrus seed extract, as a natural antimicrobial is not proven. Its effectiveness is scientifically unverified. It has been claimed to have strong antimicrobial with proven activity against bacteria and fungi. However, multiple studies have shown the efficacy of grapefruit seed extract as an antimicrobial is not demonstrated. Although GSE is promoted as a highly effective plant-based preservative by some natural personal care manufacturers, studies indicate the universal antimicrobial activity associated with GSE preparations is merely due to contamination with synthetic preservatives.{{cite journal | url=https://doi.org/10.1021/jf060543d | doi=10.1021/jf060543d | title=Development and Validation of an HPLC/UV/MS Method for Simultaneous Determination of 18 Preservatives in Grapefruit Seed Extract | date=2006 | last1=Ganzera | first1=Markus | last2=Aberham | first2=Anita | last3=Stuppner | first3=Hermann | journal=Journal of Agricultural and Food Chemistry | volume=54 | issue=11 | pages=3768–3772 | pmid=16719494 }}{{cite journal | url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?itool=abstractplus&db=pubmed&cmd=Retrieve&dopt=abstractplus&list_uids=11453769 | pmid=3769 | date=1976 | last1=Schwitter | first1=G. | last2=Beach | first2=J. | title=Bone marrow transplantation in children | journal=The Nursing Clinics of North America | volume=11 | issue=1 | pages=49–57 | doi=10.1016/S0029-6465(22)01932-6 | s2cid=5709193 }}{{cite journal | url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=10399191&query_hl=1 | pmid=9191 | date=1976 | last1=Moore | first1=P.

• HGH controversies There are many controversies around the claims, products, and businesses related to the use of growth hormone as an anti-aging therapy. Most of this controversy falls into two categories. The first, claims of exaggerated, misleading, or unfounded assertions that real growth hormone treatment slows or reverses the effects of aging The second is the sale of products that fraudulently or misleadingly purport to be growth hormone or to increase the user's own secretion of natural human growth hormone to a beneficial degree. Solid medical evidence is harder to find, and appears to indicate mixed results. It is likely that there is some advantage, but it is also evident that benefits are being exaggerated by some for commercial gain.{{cite web | title = "HGH" Pills and Sprays: Human Growth Hype? | work = FTC Consumer Alert | publisher = Federal Trade Commission | date = June 2005 | url = http://www.ftc.gov/bcp/conline/pubs/alerts/hghalrt.pdf | accessdate = 2006-11-19 }} Chronic use of hGH is not well studied, except when used in children for acute growth deficiencies.

• Journalism scandals Journalism scandals are high-profile incidents or acts, whether intentional or accidental, that run contrary to the 'ideal' mission of journalism: to report news events and issues accurately and fairly. Journalistic scandals include plagiarism, fabrication and omission of information, breaking the law or violating ethical rules, staging or altering the event being documented, or making substantial reporting or researching errors that result lead to libelous or defamatory statements.Lou Boccardi describes lesson from journalism scandals as a failure of diligence and execution; we need to do our jobs better (September 23, 2005) [http://www.gannett.com/go/newswatch/2005/september/nw0923-1.htm The Associated Press Article]
• Low-carbohydrate diet Low-carbohydrate diets or low carb diets are nutritional programs that advocate restricted carbohydrate consumption, based on research that ties consumption of certain carbohydrates with increased blood insulin levels, and overexposure to insulin with metabolic syndrome (the most recognized symptom of which is obesity). Under these dietary programs, foods high in digestible carbohydrates (sugars and starches) are limited or replaced with foods containing a higher percentage of proteins, fats, and/or fiber. In recent years, studies have expressed potential health risks with this type of diet.{{cite journal | url=http://jama.ama-assn.org/cgi/content/abstract/289/14/1837 | doi=10.1001/jama.289.14.1837 | title=Efficacy and Safety of Low-Carbohydrate Diets | date=2003 | last1=Bravata | first1=Dena M. | last2=Sanders | first2=Lisa | last3=Huang | first3=Jane | last4=Krumholz | first4=Harlan M. | last5=Olkin | first5=Ingram | last6=Gardner | first6=Christopher D. | last7=Bravata | first7=Dawn M. | journal=JAMA | volume=289 | issue=14 | pages=1837–1850 | pmid=12684364 }}http://content.nejm.org/cgi/content/abstract/355/19/1991 Article]
• Lunaception Lunaception is a form of birth control that depends upon the woman practicing it to align her menstrual cycle with the phases of the moon. The method was developed by Louise Lacey in 1974 through her book, "Lunaception : a feminine odyssey into fertility and contraception." The fundamental premise of the method is that nature and the universe are full of rhythms and cycles. Women can come into balance with their own fertility by paying attention to the evolutionary connection between menstruation and the moon. The method has never been tested under controlled scientific conditions and is therefore termed a pseudoscience.[http://www.lunaception.net/index.htm Louise Lacey's webpage]
• Megavitamin therapy In nutrition and Complementary and alternative medicine (CAM), the term megavitamin therapy is used by its proponents to describe the use of large amounts of vitamins, often many times greater than the recommended dietary allowance (RDA), to prevent or treat many types of diseases.

• Paraben Parabens are a group of chemicals widely used as preservatives in the cosmetic and pharmaceutical industries. Parabens are effective preservatives in many types of formulas. These compounds are used primarily for their bacteriocidal and fungicidal properties. They can be found in shampoos, commercial moisturizers, shaving gels, cleansing gels, personal lubricants, topical pharmaceuticals and toothpaste. They are also used as food additives.

• Trans fat Most Trans fatty acids (commonly termed trans fats) consumed today are industrially created as a side effect of partial hydrogenation of plant oils — a process that changes a fat's molecular structure (raising its melting point and reducing rancidity) but this process also results in a proportion of the changed fat becoming trans fat. Unlike other fats, trans fats are neither required nor beneficial for health.{{cite book|last = Food and nutrition board, institute of medicine of the national academies | title = Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids (Macronutrients) | publisher = National Academies Press | date = 2005 | pages = 423 | doi = 10.17226/10490 | isbn = 978-0-309-08525-0 | url = http://www.nap.edu/openbook/0309085373/html/423.html}} Eating trans fat increases the risk of coronary heart disease.{{cite book|last = Food and nutrition board, institute of medicine of the national academies | title = Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids (Macronutrients) | publisher = National Academies Press | date = 2005 | pages = 504 | url = http://darwin.nap.edu/books/0309085373/html/504.html}} For these reasons, health authorities worldwide recommend that consumption of trans fat be reduced to trace amounts.

• UFO conspiracy theory A UFO conspiracy theory is any one of many often overlapping conspiracy theories which argue that evidence of the reality of unidentified flying objects is being suppressed. Such theories often incorporate the idea that governments are in fact in communication or cooperation with extraterrestrials. Some of these theories claim that the government is explicitly allowing alien abduction in exchange for technology. Though widely known amongst the general public (and a staple of some types of fiction, such as the X Files), such ideas have seen little support from mainstream society.Clark, Jerome.

• Urban legends An urban legend is a kind of modern folklore consisting of stories often thought to be factual by those circulating them. The term is often used with a meaning similar to the expression "apocryphal story." Urban legends are not necessarily untrue, but they are often false, distorted, exaggerated, or sensationalized. Despite the name, urban legends do not necessarily take place in an urban setting. The name is designed to differentiate them from traditional folklore in preindustrial times.[http://www.snopes.com/ Snopes - Urban Legends Reference Pages][http://www.scambusters.org/legends.html ScamBusters on Urban Legends][http://hoaxbusters.ciac.org/ Hoaxbusters][http://www.tafkac.org The AFU And Urban Legends Archive][http://urbanlegends.about.com About.com: Urban Legends and Folklore][http://dsc.discovery.com/fansites/mythbusters/mythbusters.html Myth Busters TV show][http://www.panam.edu/faculty/mglazer/isclr/isclr.htm The International Society for Contemporary Legend Research]

While positions vary from outright rejection of the practice to calls for more selective and cautious use of vaccination, some of the following arguments are typically invoked are: Critics claim that the public health benefits of vaccinations are exaggerated. They further claim that the mortality rates of some illnesses were already dramatically reduced before vaccines were introduced, and claim that further reductions cannot immediately be attributed to vaccines. Additionally, secondary and long-term effects on the immune system from introducing immunogens and adjuvants directly into the body are not fully understood. Some autoimmune diseases like Acute disseminated encephalomyelitis, Guillain-Barré syndrome, Transverse myelitis and multiple sclerosis are known to be connected to vaccines, which suggests other autoimmune disorders might also be vaccine-related.[http://us.gsk.com/products/assets/us_engerixb.pdf engerix-b]Pseudoscience behind flu vaccination from Bill Sardi's Knowledge of Health [http://www.knowledgeofhealth.com/report.asp?story=Pseudoscience%20behind%20flu%20vaccination&catagory=Flu,%20Health%20Agencies,%20Vaccines Article]

• Ad hominem An ad hominem argument, also known as argumentum ad hominem (Latin: "argument to the person", "argument against the man") is a logical fallacy consisting of replying to an argument by attacking or appealing to the person making the argument, rather than by addressing the substance of the argument. It is most commonly used to refer specifically to the ad hominem abusive, or argumentum ad personam, which consists of criticizing or personally attacking an argument's proponent in an attempt to discredit that argument.{{cite book

• Anti-intellectualism Anti-intellectualism describes a sentiment of hostility towards, or mistrust of, intellectuals and intellectual pursuits. This may be expressed in various ways, such as an attack on the merits of science, education, or literature. Anti-intellectuals often perceive themselves as champions of the ordinary people and egalitarianism against elitism, especially academic elitism. These critics argue that heavily educated people form an insular social class that tends to dominate political discourse and higher education (academia).Anti-intellectualism in American Life, by Richard Hofstadter: {{ISBN|0-394-70317-0}}Anti-Intellectualism in American Media, by Dane S.

• Consciousness causes collapse Consciousness causes collapse is the theory that observation by a conscious observer is responsible for the wavefunction collapse in quantum mechanics. It is an attempt to solve the Wigner's friend paradox by simply stating that collapse occurs at the first "conscious" observer. Supporters claim this is not a revival of substance dualism, since (in a ramification of this view) consciousness and objects are entangled and cannot be considered as separate. Nevertheless, the doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with Quantum Mechanics and with facts established by experiment."Bernard d'Espagnat, Scientific American, Nov. 1979.

• Crank (person) "Crank" is a pejorative term for a person who holds some belief which the vast majority of his contemporaries would consider false, clings to this belief in the face of all counterarguments or evidence presented to him. The term implies that a "cranky" belief is so wildly at variance with some commonly accepted truth as to be ludicrous, arguing with the crank is useless, because he will invariably dismiss all evidence or arguments which contradict his cranky belief. Common synonyms for "crank" include kook and crackpot.{{cite book | author=Dudley, Underwood | title=A Budget of Trisections | location=New York | publisher= Springer-Verlag | year=1987 | isbn=0-387-96568-8 }}{{cite book | author=Dudley, Underwood | title=Mathematical Cranks | location=Washington, D.C. | publisher= Mathematical Association of America | year=1992 | isbn=0-88385-507-0 }}{{cite book | author=Dudley, Underwood | title=The Trisectors | location=Washington, D.C. | publisher= Mathematical Association of America | year = 1996 | isbn=0-88385-514-3 }}{{cite book | author=Dudley, Underwood | title=Numerology: Or, What Pythagoras Wrought | location=Washington, D.C. | publisher= Mathematical Association of America | year = 1997 | isbn=0-88385-524-0 }}{{cite book | author=Eves, Howard | title= Mathematical Circles Squared; A Third Collection of Mathematical Stories and Anecdotes | location=Boston | publisher= Prindle, Weber & Schmidt | year=1972 | isbn= 0-87150-154-6 }}{{cite book | author=Gardner, Martin | title= Fads and Fallacies in the Name of Science | location=New York | publisher= Dover | year=1957 | isbn= 0-486-20394-8 | lccn= 57003844 }}{{cite journal |author1=Kruger, Justin |author2=David Dunning |name-list-style=amp | title=Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments | journal=J.

• Fraud In the broadest sense, a fraud is a deception made for personal gain. The specific legal definition varies by legal jurisdiction. Fraud is a crime, and is also a civil law violation. Many hoaxes are fraudulent, although those not made for personal gain are not technically frauds.

If the person is unaware of the evidence, their position is ignorance, even if in agreement with the scientific conclusion.Intellectual Dishonesty Meanings [http://c2.com/cgi/wiki?IntellectualDishonesty Definition]

• Pathological science Pathological science is a neologism that describes the process in science in which people are tricked into false results by subjective effects, wishful thinking or threshold interactions. It found resonance among skeptical scientists, who enjoy debunking recurrent pseudoscientific views and claims.Irving Langmuir, "Colloquium on Pathological Science", held at The Knolls Research Laboratory, December 18, 1953. Kenneth Steiglitz, Professor of Computer Science, Princeton University. [http://www.cs.princeton.edu/~ken/Langmuir/langmuir.htm Transcript] See also: I.

• Plagiarism Plagiarism is the practice of claiming, or implying, original authorship, or incorporating material from someone else's written or creative work in whole or in part, into ones own, without adequate acknowledgment. The written or creative work which is plagiarized may be a book, article, musical score, film script, or other work. Unlike cases of forgery, in which the authenticity of the writing, document, or some other kind of object, itself is in question, plagiarism is concerned with the issue of false attribution.[http://www.uk-student.net/modules/wfsection/viewarticles.php?category=8 UK Student Portal - Academic Directory: Plagiarism][http://www.ncusd203.org/central/html/where/plagiarism_stoppers.html Plagiarism Stoppers : A Teachers Guide][http://www.turnitin.com/research_site/e_what_is_plagiarism.html What is plagiarism?]
• Pseudoscience Pseudoscience, or junk science, is any body of knowledge, methodology, belief, or practice that claims to be scientific but does not follow the scientific method."Pseudoscientific - pretending to be scientific, falsely represented as being scientific", from the Oxford American Dictionary, published by the Oxford English Dictionary. Pseudosciences may appear scientific, but they do not adhere to the testability requirement of the scientific methodFor example, Hewitt et al. Conceptual Physical Science Addison Wesley; 3 edition (July 18, 2003) {{ISBN|0-321-05173-4}}, Bennett et al. The Cosmic Perspective 3e Addison Wesley; 3 edition (July 25, 2003) {{ISBN|0-8053-8738-2}} and are often in conflict with current scientific consensus.
• Pseudoskepticism"Marcello Truzzi, [http://www.anomalist.com/commentaries/pseudo.html On Pseudo-Skepticism]" Zetetic Scholar (1987) No. 12/13, 3-4.
• Quackery Quackery is a derogatory term that is defined as the "medical practice and advice based on observation and experience in ignorance of scientific findings. The dishonesty of a charlatan."[http://dictionary.reference.com/browse/quackery Definition of Quackery] - Online dictionary A "quack" is "a fraudulent or ignorant pretender to medical skill. A person who pretends, professionally or publicly, to have skill, knowledge, or qualifications he or she does not possess; a charlatan."[http://dictionary.reference.com/browse/quack Definition of quack] - Online dictionary "Health fraud" is often used as a synonym for quackery, but this use can be problematic, since quackery can exist without fraud, a word which always implies deliberate deception.[http://www.quackwatch.org/01QuackeryRelatedTopics/quackdef.html Quackery: How Should It Be Defined?] The word "quack" derives from "quacksalver," an archaic word originally of Dutch origin (spelled kwakzalver in contemporary Dutch), meaning "boaster who applies a salve." [http://www.bartleby.com/61/60/Q0006000.html quacksalver]- American Heritage Dictionary The correct meaning of the German word "quacksalber" is "questionable salesperson (literal translation: quack salver)." In the Middle Ages the word quack itself meant "shouting. The quacksalvers sold their wares on the market shouting in a loud voice."

• Self-deception Self-deception is a process of denying or rationalizing away the relevance, significance, or importance of opposing evidence and logical argument. When one can believe their own "lie" (i.e., their presentation that is biased toward their own self-interest), the theory goes, they will consequently be better able to persuade others of its "truth." Self-deception enables someone to believe their distortions, and they will not present such signs of deception and will therefore appear to be telling the truth.[http://www.skepdic.com/selfdeception.html Self-deception article][http://plato.stanford.edu/entries/self-deception/ Self-Deception (Stanford Encyclopedia of Philosophy)]

• Self-serving bias A self-serving bias occurs when people are more likely to claim responsibility for successes than failures. It may also manifest itself as a tendency for people to evaluate ambiguous information in a way beneficial to their interests. This happens in a way that could be unknown consciously to the person, flattering their own views.Miller, D. T., & Ross, M. (1975). Self-serving biases in the attribution of causality: Fact or fiction? Psychological Bulletin, 82, 213-225.Babcock, L. & Loewenstein, G., (1997).

• Skepticism In ordinary usage, skepticism or scepticism (UK spelling) refers to an attitude of doubt or a disposition to incredulity either in general or toward a particular object, the doctrine that true knowledge or knowledge in a particular area is uncertain, or the method of suspended judgment, systematic doubt, or criticism that is characteristic of skeptics (Merriam–Webster). In philosophy, skepticism refers more specifically to any one of several propositions. These include propositions about the limitations of knowledge, a method of obtaining knowledge through systematic doubt and continual testing, the arbitrariness, relativity, or subjectivity of moral values, a method of intellectual caution and suspended judgment, a lack of confidence in positive motives for human conduct or positive outcomes for human enterprises, that is, cynicism and pessimism (Keeton, 1962).[http://pantheon.yale.edu/~kd47/responding.htm Responding to Skepticism], by Keith DeRose.

• Wishful thinking Wishful thinking is the formation of beliefs and making decisions according to what might be pleasing to imagine instead of by appealing to evidence or rationality.[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=16156178&dopt=Citation A study demonstrating wishful thinking in memory][http://humbugonline.blogspot.com/2005/01/examples-of-wishful-thinking.html Examples of Wishful Thinking] @ Humbug!
