The integrity of the scientific basis of medicine is under attack from numerous fronts. It is not only the intrusion of pseudoscience and mysticism into mainstream institutions of medicine, but also attempts to distort or game the scientific process for ideological and financial reasons.
Ideological groups such as the anti-vaccine movement, or grassroots organizations promoting pseudodiseases such as chronic Lyme, electromagnetic sensitivity, or Morgellon’s often misrepresent the scientific evidence while they lobby for special privilege to avoid the science-based standard of care within medicine.
Pharmaceutical companies, with billions on the line, have been very creative in figuring out ways to optimize their chances of getting FDA approval for their drugs, and then promoting their drugs to the medical community. Ghost-writing white papers, hiding negative trials, and designing trials to maximize positive outcomes have all been documented.
