Pseudoscience is defined as a body of knowledge, methodology, belief, or practice that is claimed to be scientific or made to appear scientific, but does not adhere to the scientific method,[2][3][4] lacks supporting evidence or plausibility,[5] or otherwise lacks scientific status.[6] The term comes from the Greek root pseudo- (false or pretending) and "science" (from Latin scientia, meaning "knowledge"). An early recorded use was in 1843 by French physiologist François Magendie,[1] who is considered a pioneer in experimental physiology.
