Good point. It should both make future experiments more accurate and also debunk similar claims more easily. Science isn't a bunch of scientists saying "we doubt it'll work"—science is a bunch of scientists experimentally proving it doesn't work. The people funding the scientists decide what's worth testing. In this case, the possible benefit vastly outweighed the cost of testing. To fix the head-to-wall metaphor: in some experiments, subjects who banged their heads against the wall reported being cured of all mental illness. However more rigorous tests showed this remarkable effect was actually a placebo caused by the subjects believing they were involved in making history.
