Through Fraud, Medicine and Middle Ages

Common elements of general quackery include questionable diagnoses using questionable diagnostic tests, as well as untested or refuted treatments, especially for serious diseases such as cancer. Quackery is often described as "health fraud" with the salient characteristic of aggressive promotion.

Definition

Psychiatrist and author Stephen Barrett of Quackwatch defines quackery as "the promotion of unsubstantiated methods that lack a scientifically plausible rationale" and more broadly as:

"anything involving overpromotion in the field of health." This definition would include questionable ideas as well as questionable products and services, regardless of the sincerity of their promoters. In line with this definition, the word "fraud" would be reserved only for situations in which deliberate deception is involved.

In addition to the ethical problems of promising benefits that are not likely to occur, quackery might cause people to forego treatments that are more likely to help them, in favor of ineffective treatments given by the "quack".

American pediatrician Paul Offit has proposed four ways in which alternative medicine "becomes quackery":

  1. "by recommending against conventional therapies that are helpful."
  2. "by promoting potentially harmful therapies without adequate warning."
  3. "by draining patients' bank accounts ..."
  4. "by promoting magical thinking ..."

Since it is difficult to distinguish between those who knowingly promote unproven medical therapies and those who are mistaken as to their effectiveness, United States courts have ruled in defamation cases that accusing someone of quackery or calling a practitioner a quack is not equivalent to accusing that person of committing medical fraud. However, the FDA makes little distinction between the two. To be considered a fraud, it is not strictly necessary for one to know they are misrepresenting the benefits or risks of the services offered.
