Serious encyclopedias: Serious and respected encyclopedias and reference works are generally expected to provide overviews of scientific topics that are in line with respected scientific thought. Wikipedia aspires to be such a respected work.
Obvious pseudoscience: Theories which, while purporting to be scientific, are obviously bogus may be so labeled and categorized as such without more.
Generally considered pseudoscience: Theories which have a following, such as astrology, but which are generally considered pseudoscience by the scientific community may properly contain that information and may be categorized as pseudoscience.
Questionable science: Theories which have a substantial following, such as psychoanalysis, but which some critics allege to be pseudoscience, may contain information to that effect, but generally should not be so characterized.
