Here would be the questions to ask in determining whether or not this is bad science. Are we to trust that the children have not been coached? Are we to trust that the stories are truth and in fact not fabricated. Is there any way to prove without doubt one way or the other? Probably not. Thus this does not follow the scientific method. Additionally, this is not exactly easily replicated. So it is not that this is bad science, it might be considered "not good science" by the standards of the scientific method. However, it is reasonable and conceivable that just because something cannot be proven via the scientific method, does not equate to it being false or true neccessarily. Consequently, there will always be some doubt and skepticism should be utilized.
