"Many writers on pseudoscience have emphasized that pseudoscience is non-science posing as science. The foremost modern classic on the subject (Gardner 1957) bears the title Fads and Fallacies in the Name of Science. According to Brian Baigrie(1988, 438), '[w]hat is objectionable about these beliefs is that they masquerade as genuinely scientific ones.' These and many other authors assume that to be pseudoscientific, an activity or a teaching has to satisfy the following two criteria (Hansson 1996):(1)it is not scientific, and (2) its major proponents try to create the impression that it is scientific."Hansson 2008 harvnb模板錯誤: 多個指向目標 (2個): CITEREFHansson2008 (幫助)
'"claims presented so that they appear [to be] scientific even though they lack supporting evidence and plausibility"(p. 33). In contrast, science is "a set of methods designed to describe and interpret observed and inferred phenomena, past or present, and aimed at building a testable body of knowledge open to rejection or confirmation"(p. 17)'Shermer 1997,(this was the definition adopted byArchive-It的存檔,存檔日期2015-08-18 the National Science Foundation).

From a practical point of view, the distinction is important for decision guidance in both private and public life. Since science is our most reliable source of knowledge in a wide variety of areas, we need to distinguish scientific knowledge from its look-alikes. Due to the high status of science in present-day society, attempts to exaggerate the scientific status of various claims, teachings, and products are common enough to make the demarcation issue pressing in many areas.
However, from the "them vs. us" polarization that its usage engenders, the term may also have a positive function because "[the] 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

A particularly radical reinterpretation of science comes from Paul Feyerabend, "the worst enemy of science"... Like Lakatos, Feyerabend was also a student under Popper. In an interview with Feyerabend in Science, [he says] "Equal weight... should be given to competing avenues of knowledge such as astrology, acupunture, and witchcraft..."

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."

"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!"

Public Knowledge About S&T. [August 28, 2013]. (原始內容存檔於2015-08-18). Surveys conducted in the United States and Europe reveal that many citizens do not have a firm grasp of basic scientific facts and concepts, nor do they have an understanding of the scientific process. In addition, belief in pseudoscience (an indicator of scientific illiteracy) seems to be widespread among Americans and Europeans.
