P Nombre y apellido seudosciences are by-products of the prestige of science as a social enterprise and as a means of obtaining knowledge. Their character is inherently negative, given that, by definition, a pseudoscience is an intellectual fraud consisting of products, practices, or ideas unconnected with scientific rationality that are asserted as science to society, in an act of rhetorical enhancement of their dubious goodness. For several decades they have attracted great interest, not only because of the strange and sometimes extreme nature of their contents, but also because of the alarming penetration they have reached in highly sensitive environments, such as the education or health system systems.
