The following characteristics have been argued by the cited authors to be useful
in identifying pseudoscience.

Use of vague, exaggerated or untestable claims
Assertion of scientific claims that are vague rather than precise, and that lack
specific measurements as a basis [18].
Failure to make use of operational definitions [19]
Failure to adhere to the principle of parsimony, i.e. failing to seek an
explanation that requires the fewest possible additional assumptions when
multiple viable explanations are possible (see: Occam's Razor) [20]
Use of obscurantist language. Many proponents of pseudoscience use grandiose or
highly technical jargon in an effort to provide their disciplines with the
superficial trappings of science.[21]

Anti-science is very popular with the devotees of thermionics in particular
where the proponents often simply dismiss the relevance of the scientific method
entirely.
