What is Conspiracy theory?

The Eye of Providence, or the all-seeing eye of God, seen here on the US$1 bill, has been taken by some to be evidence of a conspiracy involving the founders of the United States and the Illuminati

A conspiracy theory is an explanation for an event or situation that invokes a conspiracy by sinister and powerful groups, often political in motivation, when other explanations are more probable. The term has a pejorative connotation, implying that the appeal to a conspiracy is based on prejudice or insufficient evidence. Conspiracy theories resist falsification and are reinforced by circular reasoning: both evidence against the conspiracy and an absence of evidence for it are re-interpreted as evidence of its truth, whereby the conspiracy becomes a matter of faith rather than something that can be proved or disproved.

Research suggests that conspiracist ideation—belief in conspiracy theories—can be psychologically harmful or pathological and that it is correlated with psychological projection, paranoia and Machiavellianism. Conspiracy theories once limited to fringe audiences have become commonplace in mass media, emerging as a cultural phenomenon of the late 20th and early 21st centuries.

Psychologists attribute finding a conspiracy where there is none to a mental illness called illusory pattern perception.

Examples

take any matter as its subject, but certain subjects attract greater interest than others. Favored subjects include famous deaths and assassinations, morally dubious government activities, suppressed technologies, and “false flag” terrorism. Among the longest-standing and most widely recognized conspiracy theories are notions concerning the assassination of John F. Kennedy, the 1969 Apollo moon landings, and the 9/11 terrorist attacks, as well as numerous theories pertaining to alleged plots for world domination by various groups both real and imaginary.

Evidence vs. conspiracy theory

Belief in conspiracy theories is generally based not on evidence, but in the faith of the believer. Noam Chomsky contrasts conspiracy theory to institutional analysis which focuses mostly on the public, long-term behavior of publicly known institutions, as recorded in, for example, scholarly documents or mainstream media reports. Conspiracy theory conversely posits the existence of secretive coalitions of individuals and speculates on their alleged activities.

Clare Birchall at King's College London describes conspiracy theory as a "form of popular knowledge or interpretation". The use of the word 'knowledge' here suggests ways in which conspiracy theory may be considered in relation to legitimate modes of knowing. The relationship between legitimate and illegitimate knowledge, Birchall claims, is closer than common dismissals of conspiracy theory contend.

Theories involving multiple conspirators that are proven to be correct, such as the Watergate scandal, are usually referred to as "investigative journalism" or "historical analysis" rather than conspiracy theory. By contrast, the term "Watergate conspiracy theory" is used to refer to a variety of hypotheses in which those convicted in the conspiracy were in fact the victims of a deeper conspiracy.
