A pseudoscience is any body of knowledge purported to be scientific or supported by science but which fails to comply with the scientific method. Pseudoscience is a kind of counterfeit or masquerade of science that makes use of some of the superficial trappings of science but does not involve the substance of science.
A pseudoscience is set of ideas based on theories put forth as scientific when they are not scientific.
Scientific theories are characterized by such things as
( a ) being based upon empirical observation rather than the authority of some sacred text;
( b ) explaining a range of empirical phenomena;
( c ) being empirically tested in some meaningful way, usually involving testing specific predictions deduced from the theory;
( d ) being confirmed rather than falsified by empirical tests or with the discovery of new facts;
( e ) being impersonal and therefore testable by anyone regardless of personal religious or metaphysical beliefs;
( f ) being dynamic and fecund, leading investigators to new knowledge and understanding of the interrelatedness of the natural world rather than being static and stagnant leading to no research or development of a better understanding of anything in the natural world; and
( g ) being approached with skepticism rather than gullibility, especially regarding paranormal forces or supernatural powers, and being fallible and put forth tentatively rather than being put forth dogmatically as infallible.
