Numerous conspiracy theories pertain to air travel and aircraft. However, the current scientific consensus holds that most conspiracy theorists are not pathological, precisely because their beliefs ultimately rely on cognitive tendencies that are neurologically hardwired in the human species and probably have deep evolutionary origins, including natural inclinations towards anxiety and agent detection. Psychologists sometimes attribute belief in conspiracy theories and finding a conspiracy where there is none to a number of psychopathological conditions such as paranoia, schizotypy, narcissism, and insecure attachment, or to a form of cognitive bias called ' illusory pattern perception'. However, they are often discredited a priori due to the cumbersome and improbable nature of many of them. In principle, conspiracy theories are not always false by default and their validity depends on evidence just as in any theory. Conspiracy theories usually deny consensus or cannot be proven using the historical or scientific method, and are not to be confused with research concerning verified conspiracies such as Germany's pretense for invading Poland in World War II. Many conspiracy theories relate to supposed clandestine government plans and elaborate murder plots. This is a list of conspiracy theories that are notable.
