is a position in which one questions the veracity of claims lacking
scientific evidence
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, although scientists also use evidence in other ways, such as when applying theories to practical problems. "Discussions about empirical ev ...

described skepticism as selecting "beliefs and conclusions that are reliable and valid to ones that are comforting or convenient" and as the study of "pitfalls of human reason and the mechanisms of deception so as to avoid being deceived by others or themselves". Brian Dunning called skepticism "the process of finding a supported conclusion, not the justification of a preconceived conclusion.''
Skeptics often focus their criticism on claims they consider implausible, dubious or clearly contradictory to generally accepted science. Scientific skeptics do not assert that unusual claims should be automatically rejected out of hand on ''a priori'' grounds—rather they argue that one should critically examine claims of paranormal or anomalous phenomena and that extraordinary claims would require extraordinary evidence in their favor before they could be accepted as having validity. From a scientific point of view, skeptics judge ideas on many criteria, including falsifiability, Occam's Razor

; for instance an experimental result is not regarded as established until it can be shown to be repeatable independently.
The Sci.Skeptic FAQ characterizes the skeptic spectrum as divided into "wet" and "dry" skeptics, primarily based on the level of engagement with those promoting claims that appear to be pseudoscience; the dry skeptics preferring to debunk and ridicule, in order to avoid giving attention and thus credence to the promoters, and the "wet" skeptics, preferring slower and more considered engagement, in order to avoid appearing sloppy and ill-considered and thus similar to the groups all skeptics opposed.[
Ron Lindsay has argued that while some non-scientific claims appear to be harmless or "soft targets", it is important to continue to address them and the underlying habits of thought that lead to them so that we do not "have a lot more people believing that 9/11 was an inside job, that climate change is a hoax, that our government is controlled by aliens, and so forth—and those beliefs are far from harmless".

Skeptical movement
With regard to the skeptical social movement, Daniel Loxton refers to other movements already promoting "humanism, atheism

He saw the demand for the new movement—a movement of people called "skeptics"—as based on a lack of interest by the scientific community to address paranormal and fringe-science claims. In line with Kendrick Frazier
Kendrick Crosby Frazier (March 19, 1942 – November 7, 2022) was an American science writer and longtime editor of '' Skeptical Inquirer'' magazine. He was also a former editor of ''Science News'', author or editor of ten books, and a Fellow o ...
, he describes the movement as a surrogate in that area for institutional science.
The movement set up a distinct field of study, and provided an organizational structure, while "the long-standing genre of individual skeptical writing" lacked such a community and background.
Skeptical organizations typically tend to have science education and promotion among their goals.
The skeptical movement has had issues with allegations of sexism. Mary Coulman identified a disparity between women and men in the movement in a 1985 skeptic newsletter.[ The skeptic movement has generally been made up of men; at a 1987 conference the members there discussed the fact that the attendees were predominantly older white men and a 1991 listing of 50 CSICOP fellows included four women.] Following a 2011 conference, Rebecca Watson, a prominent skeptic, raised issues of the way female skeptics are targeted with online harassment

including threats of sexual violence by opponents of the movement, and also raised issues of sexism within the movement itself. While she received some support in response to her discussion of sexism within the movement, she later became a target of virulent online harassment, even from fellow skeptics, after posting an online video that discussed her discomfort with being propositioned in a confined space. This became known as " Elevatorgate", based on Watson's discussion about being propositioned in a hotel elevator in the early morning after a skeptic event.
Debunking and rational inquiry
The verb "to debunk" is used to describe efforts by skeptics to expose or discredit claims believed to be false, exaggerated, or pretentious. It is closely associated with skeptical investigation or rational inquiry of controversial topics (compare list of topics characterized as pseudoscience

The scientific skepticism community has traditionally been focused on what people believe rather than why they believe—there might be psychological, cognitive or instinctive reasons for belief when there is little evidence for such beliefs. According to Hammer, the bulk of the skeptical movement's literature works on an implicit model, that belief in the irrational is being based on scientific illiteracy or cognitive illusions.

's '' Elementary Forms of the Religious Life''—Science, seen as pure and sacred (motivated by values of the mind and reason), is set apart from popular dealings with the paranormal, seen as profane (permeated by the economic and the social); obscuring the confrontation between science and religion. Hess states as well a strong tendency in othering: both skeptics and their opponents see the other as being driven by materialistic philosophy and material gain and assume themselves to have purer motives.

History
Historical roots
According to skeptic author Daniel Loxton, "skepticism is a story without a beginning or an end." His 2013 article in '' Skeptic'' magazine "Why Is There a Skeptical Movement" claims a history of two millennia of paranormal skepticism. He is of the opinion that the practice, problems, and central concepts extend all the way to antiquity and refers to a debunking tale as told in some versions of the Old Testament, where the Prophet Daniel exposes a tale of a "living" statue as a scam. According to Loxton, throughout history, there are further examples of individuals practicing critical inquiry and writing books or performing publicly against particular frauds and popular superstitions, including people like Lucian of Samosata
Lucian of Samosata (Λουκιανὸς ὁ Σαμοσατεύς, 125 – after 180) was a Hellenized Syria (region), Syrian satire, satirist, rhetorician and pamphleteer who is best known for his characteristic tongue-in-cheek style, with whi ...

Two early important works influential to the skeptical movement were Daniel Webster Hering's ''Foibles and Fallacies of Science'' (1924) and D. H. Rawcliffe's '' The Psychology of the Occult''.
Loxton mentions the Belgian Comité Para (1949) as the oldest "broad mandate" skeptical organization. Although it was preceded by the Dutch Vereniging tegen de Kwakzalverij (VtdK) (1881), which is therefore considered the oldest skeptical organization by others, the VtdK only focuses on fighting quackery, and thus has a 'narrow mandate'.
