Pseudoscience




Pseudoscience is any body of knowledge, methodology, belief, or practice that claims to be Scientific or is made to appear scientific, but does not adhere to the basic requirements of the Scientific Method ."''Pseudoscientific - pretending to be scientific, falsely represented as being scientific''", from the ''Oxford American Dictionary'', published by the Oxford English Dictionary ."''A pretended or spurious science; a collection of related beliefs about the world mistakenly regarded as being based on scientific method or as having the status that scientific truths now have.''", from the Oxford English Dictionary Second Edition 1989.For 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''See also'', e.g., Gauch HG Jr. ''Scientific Method in Practice'' (2003)

The term ''pseudoscience'' is based on the Greek root ''pseudo-'' (false or pretending) and ''science'' (derived from Latin ''scientia'', meaning knowledge). The first recorded use was in 1843 by French physiologist François Magendie Magendie, F (1843) ''An Elementary Treatise on Human Physiology.'' 5th Ed. Tr. John Revere. New York: Harper, p 150. Magendie refers to phrenology as "''a pseudo-science of the present day''" (note the hyphen). considered a pioneer in experimental physiology.

The term has Negative Connotations , because it is used to indicate that subjects so labeled are inaccurately or deceptively portrayed as science.However, from the "them vs. us" polarization that its usage engenders, the term may also have a positive function because "'' {Link without Title} derogatory labeling of others often includes an unstated self-definition'' "(p.266); and, from this, the application of the term also implies "''a unity of science, a privileged tree of knowledge or space from which the pseudoscience is excluded, and the user's right to belong is asserted'' " (p.286) -- Still A & Dryden W (2004) "The Social Psychology of "Pseudoscience": A Brief History", ''J Theory Social Behav'' 34:265-290 Accordingly, those labeled as practicing or advocating a "pseudoscience" normally reject this classification.

As it is taught in certain introductory science classes, pseudoscience is any subject that appears superficially to be scientific or whose proponents state is scientific but nevertheless contravenes the entitled "Science & Pseudoscience" {Link without Title}

Beyond the initial introductory analyses offered in science classes, there is some Epistemological disagreement about whether it is possible to distinguish "science" from "pseudoscience" in a reliable and Objective way.The philosopher of science Paul Feyerabend in particular is associated with the view that attempts to distinguish science from non-science are flawed and pernicious. "The idea that science can, and should, be run according to fixed and universal rules, is both unrealistic and pernicious. ... the idea is detrimental to science, for it neglects the complex physical and historical conditions which influence scientific change. It makes our science less adaptable and more dogmatic:" {Link without Title}

Pseudosciences may be characterised by the use of vague, exaggerated or untestable claims, over-reliance on confirmation rather than refutation, lack of openness to testing by other experts, and a lack of progress in theory development.


BACKGROUND

The standards for determining whether a body of Knowledge , Methodology , or Practice is scientific can vary from field to field, but involve agreed principles including Reproducibility and Intersubjective Verifiability .''e.g. '' Gauch HG Jr. ''Scientific Method in Practice'' (2003) 3-5 ''ff'' Such principles aim to ensure that relevant evidence can be reproduced and/or measured given the same conditions, which allows further investigation to determine whether a Hypothesis or Theory related to given Phenomena is both Valid and Reliable for use by others, including other scientists and researchers. It is expected that the Scientific Method will be applied throughout, and that Bias will be controlled or eliminated, by Double-blind studies, or statistically through fair sampling procedures. All gathered data, including experimental/environmental conditions, are expected to be documented for scrutiny and made available for Peer Review , thereby allowing further Experiment s or studies to be conducted to confirm or Falsify results, as well as to determine other important factors such as Statistical Significance , Confidence Interval s, and Margins Of Error .Gauch (2003), 191 ''ff'', especially Chapter 6, "Probability", and Chapter 7, "inductive Logic and Statistics" Fulfillment of these requirements allows others a reasonable opportunity to assess whether to rely upon the reported results in their own scientific work or in a particular field of Applied Science , Technology , Therapy , or other form of practice.

In the mid-20th Century has suggested the categories of "belief fields" and "research fields" to help distinguish between science and pseudoscience. Bunge M (1983) "Demarcating science from pseudoscience" Fundamenta Scientiae 3:369-388

Philosopher of science Paul Feyerabend has argued, from a Sociology Of Knowledge perspective, that a distinction between science and non-science is neither possible nor desirable.Feyerabend P ''Against Method: Outline of an Anarchistic Theory of Knowledge'' (1975) {Link without Title} For a perspective on Feyerabend from within the scientific community, see, e.g., Gauch (2003) at p.4: "Such critiques are unfamiliar to most scientists, although some may have heard a few distant shots from the so-called science wars." Among the issues which can make the distinction difficult are that both the theories and methodologies of science evolve at differing rates in response to new data.Thagard PR (1978) "Why astrology is a pseudoscience" (1978) In PSA 1978, Volume 1, ed. Asquith PD and Hacking I (East Lansing: Philosophy of Science Association, 1978) 223 ff. Thagard writes, at 227, 228: "We can now propose the following principle of demarcation: A theory or discipline which purports to be scientific is pseudoscientific if and only if: it has been less progressive than alternative theories over a long period of time, and faces many unsolved problems; but the community of practitioners makes little attempt to develop the theory towards solutions of the problems, shows no concern for attempts to evaluate the theory in relation to others, and is selective in considering confirmations and non confirmations." In addition, the specific standards applicable to one field of science may not be those employed in other fields. Thagard also writes from a sociological perspective and states that "elucidation of how science differs from pseudoscience is the philosophical side of an attempt to overcome public neglect of genuine science."

Both the Skeptics and the Brights Movement , most prominently represented by Richard Dawkins , Mario Bunge , Carl Sagan and James Randi , consider all forms of pseudoscience to be harmful, whether or not they result in immediate harm to their adherents. These critics generally consider that the practice of pseudoscience may occur for a number of reasons, ranging from simple naïveté about the nature of science and the Scientific Method , to deliberate deception for financial or political gain. At the extreme, issues of personal health and safety may be very directly involved, for example in the case of physical or mental therapy or treatment, or in assessing safety risks. In such instances the potential for direct harm to patients, clients, the general public, or the environment may be an issue in assessing pseudoscience. (See also Junk Science .)

The concept of pseudoscience as antagonistic to ''bona fide'' science appears to have emerged in the mid- 19th Century . Among the first recorded uses of the word "pseudo-science" was in 1844 in the ''Northern Journal of Medicine'', I 387: "That opposite kind of innovation which pronounces what has been recognized as a branch of science, to have been a pseudo-science, composed merely of so-called facts, connected together by misapprehensions under the disguise of principles".


IDENTIFYING PSEUDOSCIENCE


A field, practice, or body of knowledge might reasonably be called pseudoscientific when (1) it is presented as consistent with the accepted Norms of scientific research; but (2) it demonstrably fails to meet these norms, most importantly, in misuse of Scientific Method .Cover JA, Curd M (Eds, 1998) ''Philosophy of Science: The Central Issues'', 1-82

Subjects may be considered pseudoscientific for various reasons; Popper considered Astrology to be pseudoscientific simply because astrologers keep their claims so vague that they could never be refuted, whereas Thagard considers astrology pseudoscientific because its practitioners make little effort to develop the theory, show no concern for attempts to critically evaluate the theory in relation to others, and are selective in considering evidence. More generally, Thagard stated that pseudoscience tends to focus on resemblances rather than cause-effect relations.

Science is also distinguishable from Revelation , Theology , or Spirituality in that it claims to offer insight into the physical world obtained by "scientific" means. Systems of thought that derive from divine or inspired knowledge are not considered pseudoscience if they do not claim either to be scientific or to overturn well-established science.

Some statements and commonly held beliefs in and expert Peer Review .

If the claims of a given field can be experimentally tested and methodological standards are upheld, it is not "pseudoscience", however odd, astonishing, or counter-intuitive. If claims made are inconsistent with existing experimental results or established theory, but the methodology is sound, caution should be used; science consists of testing hypotheses which may turn out to be false. In such a case, the work may be better described as ideas that are ''not yet generally accepted''.

The following have been proposed to be indicators of poor scientific reasoning.


Use of vague, exaggerated or untestable claims

  • Assertion of scientific claims that are vague rather than precise, and that lack specific measurements.e.g. Gauch (2003) ''op cit'' at 211 ''ff'' (Probability, "Common Blunders")

  • Failure to make use of Operational Definition s. (i.e. a scientific description of the operational means in which a range of numeric measurements can be obtained).Paul Montgomery Churchland, ''Matter and Consciousness: A Contemporary Introduction to the Philosophy of Mind'' (1999) MIT Press. p.90 . "Most terms in theoretical physics, for example, do not enjoy at least some distinct connections with observables, but not of the simple sort that would permit operational ''definitions'' in terms of these observables. [..] If a restriction in favor of operational definitions were to be followed, therefore, most of theoretical ''physics'' would have to be dismissed as meaningless pseudoscience!"

  • Lack of suitable controls. This is particularly common of some alternative medicines, particularly Homeopathy where a demonstration of an effect above and beyond that of a Placebo is often absent {Link without Title} .

  • Failure to make reasonable use of the principle of )Gauch HG Jr. (2003) ''op cit'' 269 ff, "Parsimony and Efficiency"

  • Use of Obscurantist language, and misuse of apparently technical jargon in an effort to give claims the superficial trappings of science.

  • Lack of boundary conditions: Most well-supported scientific theories possess boundary conditions (well articulated limitations) under which the predicted phenomena do and do not apply.Hines T (1988) ''Pseudoscience and the Paranormal: A Critical Examination of the Evidence'' Buffalo NY: Prometheus Books. A Skeptical Inquirer Reader



Over-reliance on confirmation rather than refutation

  • Assertion of scientific claims that cannot be falsified in the event they are incorrect, inaccurate, or irrelevant (''see also'': Falsifiability )Lakatos I (1970) "Falsification and the Methodology of Scientific Research Programmes." in Lakatos I, Musgrave A (eds) ''Criticism and the Growth of Knowledge'' pp 91-195; Popper KR (1959) ''The Logic of Scientific Discovery''

  • Assertion of claims that a theory predicts something that it has not been shown to predicte.g. Gauch (2003) ''op cit'' at 178 ''ff'' (Deductive Logic, "Fallacies"), and at 211 ''ff'' (Probability, "Common Blunders").

  • e.g. {Link without Title}

''Macmilllan Encyclopedia of Philosophy'' Vol 3, "Fallacies" 174 ''ff'', esp. section on "Ignoratio elenchi"
  • Assertion that claims which have not been proven false must be true, and vice versa (''see'': Argument From Ignorance )''Macmillan Encyclopedia of Philosophy'' Vol 3, "Fallacies" 174 'ff'' esp. 177-178

  • Over-reliance on testimonials and anecdotes. Testimonial and anecdotal evidence can be useful for discovery (i.e. hypothesis generation) but should not be used in the context of justification (i.e. hypothesis testing).Bunge M (1983) Demarcating science from pseudoscience ''Fundamenta Scientiae'' 3:369-388, 381

  • Selective use of experimental evidence: presentation of data that seems to support its own claims while suppressing or refusing to consider data that conflict with its claims.Thagard (1978)''op cit'' at 227, 228

  • Reversed burden of proof. In science, the burden of proof rests on those making a claim, not on the critic. "Pseudoscientific" arguments may neglect this principle and demand that Skeptic s demonstrate beyond a reasonable doubt that a claim (e.g. an assertion regarding the efficacy of a novel therapeutic technique) is false. It is essentially impossible to prove a universal negative, so this tactic incorrectly places the burden of proof on the skeptic rather than the claimant.Lilienfeld SO (2004) ''Science and Pseudoscience in Clinical Psychology'' Guildford Press (2004) ISBN 1-59385-070-0

  • Appeals to Holism : Proponents of pseudoscientific claims, especially in organic medicine, alternative medicine, naturopathy and mental health, often resort to the “mantra of holism” to explain negative findings.Ruscio J (2001) ''Clear thinking with psychology: Separating sense from nonsense'', Pacific Grove, CA: Wadsworth



Lack of openness to testing by other experts

  • Evasion of )--- Peer review – process, perspectives and the path ahead ; Lilienfeld (2004) ''op cit'' For an opposing perspective, e.g. Peer Review as Scholarly Conformity Some proponents of theories that contradict accepted scientific theories avoid subjecting their ideas to peer review, sometimes on the grounds that peer review is biased towards established paradigms, and sometimes on the grounds that assertions cannot be evaluated adequately using standard scientific methods. By remaining insulated from the peer review process, these proponents forego the opportunity of corrective feedback from informed colleagues.Ruscio (2001) ''op cit.

  • The science community expects authors to Share Data necessary to evaluate a paper. Failure to provide adequate information for other researchers to Reproduce the claimed results is a lack of openness.Gauch (2003) ''op cit'' 124 ff"

  • Assertion of claims of secrecy or proprietary knowledge in response to requests for review of data or methodology.Gauch (2003) ''op cit'' 124 ff"



Lack of progress

  • Failure to progress towards additional evidence of its claims.Lakatos I (1970) "Falsification and the Methodology of Scientific Research Programmes." in Lakatos I, Musgrave A (eds.) ''Criticism and the Growth of Knowledge'' 91-195; Thagard (1978) ''op cit'' writes: "We can now propose the following principle of demarcation: A theory or discipline which purports to be scientific is pseudoscientific if and only if: it has been less progressive than alternative theories over a long period of time, and faces many unsolved problems; but the community of practitioners makes little attempt to develop the theory towards solutions of the problems, shows no concern for attempts to evaluate the theory in relation to others, and is selective in considering confirmations and disconfirmations." Terrence Hines has identified astrology as a subject that has changed very little in the past two millennia. Hines T , ''Pseudoscience and the Paranormal: A Critical Examination of the Evidence'', Prometheus Books, Buffalo, NY, 1988. ISBN 0-87975-419-2.

  • Thagard (1978) ''op cit'' 223 ''ff''

  • Lack of self correction: scientific research programmes make mistakes, but they tend to eliminate these errors over time. name=Ruscio120>Ruscio J (2001) ''op cit.'' p120 By contrast, theories may be accused of being pseudoscientific because they have remained unaltered despite contradictory evidence.The work ''Scientists Confront Velikovsky'' (1976) Cornell University, also delves into these features in some detail, as does the work of Thomas Kuhn , e.g. ''The Structure of Scientific Revolutions'' (1962) which also discusses some of the items on the list of characteristics of pseudoscience.



Personalization of issues

  • Tight social groups and Granfalloon s. Authoritarian Personality , Suppression Of Dissent , and Groupthink can enhance the adoption of beliefs that have no rational basis. In attempting to Confirm Their Beliefs , the group tends to identify their critics as enemies.Devilly GJ (2005) Power therapies and possible threats to the science of psychology and psychiatry ''Austral NZ J Psych'' 39:437-445(9)

  • Assertion of claims of a conspiracy on the part of the scientific community to suppress the results.e.g. archivefreedom.org which claims that "The list of suppressed scientists even includes Nobel Laureates!"

  • Attacking the motives or character of anyone who questions the claims (see Ad Hominem Fallacy ).Devilly (2005) ''op cit.''

  • e.g. {Link without Title}



Use of misleading language

  • Creating scientific-sounding terms in order to add weight to claims and persuade non-experts to believe statements that may be false or meaningless.

  • Use of uncommon terms for common substances can also be misleading. For example referring to water as Dihydrogen Monoxide (DHMO) and proclaiming that it is the main constituent of most toxic compounds.



DEMOGRAPHICS

The National Science Foundation stated that, in the USA, "pseudoscientific" beliefs became more widespread during the 1990s, peaked near 2001 and mildly declined since; nevertheless, pseudoscientific beliefs remain common in the USA. National Science Board. 2006. ''Science and Engineering Indicators 2006'' Two volumes. Arlington, VA: National Science Foundation (volume 1, NSB-06-01; NSB 06-01A) As a result, according to the NSF report, there is a lack of knowledge of pseudoscientific issues in society and pseudoscientific practices are commonly followed. Bunge (1999) states that "A survey on public knowledge of science in the United States showed that in 1988 50% of American adults [rejected evolution, and 88% [believed] astrology is a science'".

Commentators on pseudoscience perceive it in many fields; for example Pseudomathematics is a term used for mathematics-like activity undertaken either by non-mathematicians or mathematicians themselves which does not conform to the rigorous standards usually applied to mathematical theorems.


CLINICAL PSYCHOLOGY


Neurologists and clinical psychologists are concerned about the increasing amount of what they consider pseudoscience promoted in Psychotherapy and popular Psychology , and also about what they see as pseudoscientific therapies such as Neuro-linguistic Programming , EMDR , Rebirthing , Reparenting, and Primal Therapy being adopted by government and professional bodies and by the public. e.g. Drenth (2003) Herbert JD, ''et al.'' (2000) Science and pseudoscience in the development of eye movement desensitization and reprocessing: implications for clinical psychology. ''Clin Psychol Rev.'' 20:945-71 [PMID 11098395 ) They state that scientifically unsupported therapies used by popular or folk psychology might harm vulnerable members of the public, undermine legitimate therapies, and tend to spread misconceptions about the nature of the mind and brain to society at large. Norcross ''et al''.Norcross J.C. Garofalo. A. Koocher.G.P. (2006) Discredited psychological treatments and tests: a Delphi poll. ''Professional Psychology. Research and Practice'', 37: 515-522. have approached the science/pseudoscience issue by conducting a survey of experts that seeks to specify which theory or therapy is considered to be definitely discredited, and they outline 14 fields that have been definitely discredited.
