Using a standard science fair display board, Rosa devised a single-blind protocol, later described by other scientists as "simple and elegant", for a study she conducted at age nine for her 4th grade science fair. There were two series of tests. In 1996, 15 practitioners were tested at their home or office on different days over a period of several months. In 1997, 13 practitioners, including 7 from the first series, were tested on a single day. The second series was observed and videotaped by the producers of Scientific American Frontiers. Stephen Barrett, MD, of Quackwatch was senior author, her mother (Linda Rosa, RN) was lead author, and her stepfather (Larry Sarner) served as statistician when the experiment was written up for the "Journal of the American Medical Association". The study, which included an extensive literature search, was published on April 1, 1998. George Lundberg, editor of "JAMA", aware of the uniqueness of the situation, said: "Age doesn't matter. It's good science that matters, and this is good science".
