Pseudoscience.

There is a lot of pseudoscience on this forum. Before parting with your money, or wasting your valuable time, it really is worth reading up a little on the subject.

The following sections in particular apply.

* Assertion of scientific claims that are vague rather than precise, and that lack specific measurements[42]

* Use of obscurantist language, and use of apparently technical jargon in an effort to give claims the superficial trappings of science.


* Reversed burden of proof: science places the burden of proof 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 on the claimant.

Evasion of peer review before publicizing results (termed "science by press conference")

* Appealing to the need for secrecy or proprietary knowledge when an independent review of data or methodology is requested[56]


* Creating scientific-sounding terms to 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.

Personalisation 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.[61]
