The Nine Year Old, and Why That Is the Least Interesting Part

The paper was reported everywhere as the story of a child who debunked a therapy, and Emily Rosa was indeed nine when she ran the trials for a school science fair and eleven when JAMA published. That framing did the result a disservice in both directions. It let supporters treat the study as a stunt rather than an experiment, and it let critics of the practice enjoy the humiliation instead of the finding. The substantive point is duller and more damaging: the practice had been taught in nursing schools, offered in hospitals and defended in its own professional literature for roughly twenty-five years, and the simplest possible test of its central perceptual claim had not been published by anyone in that time.

A field that has not asked its own easiest question has a problem that no single result can fix. The response from practitioners was to argue that the test was artificial, that perceiving a field in a laboratory is not the same as working with a patient, and that the therapeutic benefit does not depend on the perception. Those replies may be true. They also concede the specific claim the test examined, and no comparable test has since produced a positive result. The test is now a standard teaching example of how cheap a decisive experiment can be.
