BIAS MAY BE PRESENT. Quackwatch is an international network of people who are concerned about health-related frauds, myths, fads, fallacies, and misconduct. Its primary focus is on quackery-related information that is difficult or impossible to get elsewhere. Founded by Dr. Stephen Barrett in 1969 as the Lehigh Valley Committee Against Health Fraud (Allentown, Pennsylvania), it was incorporated in 1970. In 1997, it assumed its current name and began developing a worldwide network of volunteers and expert advisors.
