Use of vague, exaggerated or untestable claims
- Assertion of scientific claims that are vague rather than precise, and that lack specific measurements
- Failure to make use of operational definitions (i.e. publicly accessible definitions of the variables, terms, or objects of interest so that persons other than the definer can independently measure or test them)
- Failure to make reasonable use of the principle of parsimony, i.e. failing to seek an explanation that requires the fewest possible additional assumptions when multiple viable explanations are possible
- Use of obscurantist language, and use of apparently technical jargon in an effort to give claims the superficial trappings of science
- Lack of boundary conditions: Most well-supported scientific theories possess well-articulated limitations under which the predicted phenomena do and do not apply
- Lack of effective controls, such as placebo and double-blind, in experimental design
- Lack of understanding of basic and established principles of physics and engineering
Over-reliance on confirmation rather than refutation
- Assertions that do not allow the logical possibility that they can be shown to be false by observation or physical experiment
- Assertion of claims that a theory predicts something that it has not been shown to predict
- Assertion that claims which have not been proven false must be true, and vice versa
- Over-reliance on testimonial, anecdotal evidence, or personal experience
- Presentation of data that seems to support its claims while suppressing or refusing to consider data that conflict with its claims
- Reversed burden of proof: In science, the burden of proof rests on those making a claim, not on the critic. "Pseudoscientific" arguments may neglect this principle and demand that skeptics demonstrate beyond a reasonable doubt that a claim (e.g. an assertion regarding the efficacy of a novel therapeutic technique) is false. It is essentially impossible to prove a universal negative, so this tactic incorrectly places the burden of proof on the skeptic rather than the claimant
- Appeals to holism as opposed to reductionism
Lack of openness to testing by other experts
- Evasion of peer review before publicizing results (called "science by press conference")
- Some agencies, institutions, and publications that fund scientific research require authors to share data so others can evaluate a paper independently. Failure to provide adequate information for other researchers to reproduce the claims contributes to a lack of openness
- Appealing to the need for secrecy or proprietary knowledge when an independent review of data or methodology is requested
Absence of progress
- Failure to progress towards additional evidence of its claims
- Lack of self-correction: scientific research programs make mistakes, but they tend to eliminate these errors over time
- Statistical significance of supporting experimental results does not improve over time and are usually close to the cutoff for statistical significance. Normally, experimental techniques improve or the experiments are repeated, and this gives ever stronger evidence. If statistical significance does not improve, this typically shows the experiments have just been repeated until a success occurs due to chance variations
Personalization of issues
- Tight social groups and authoritarian personality, suppression of dissent, and groupthink can enhance the adoption of beliefs that have no rational basis. In attempting to confirm their beliefs, the group tends to identify their critics as enemies
- Assertion of claims of a conspiracy on the part of the scientific community to suppress the results
- Attacking the motives or character of anyone who questions the claims
Use of misleading language
- Creating scientific-sounding terms to add weight to claims and persuade nonexperts to believe statements that may be false or meaningless: For example, a long-standing hoax refers to water by the rarely used formal name "dihydrogen monoxide" and describes it as the main constituent in most poisonous solutions to show how easily the general public can be misled
- Using established terms in idiosyncratic ways, thereby demonstrating unfamiliarity with mainstream work in the discipline
