Investigations under conditions favorable to the medium cannot be termed “investigations.” They are nothing more than a demonstration of the medium’s power to divert the attention, carrying it at will to any place they wish and numbing the subconscious mind. Under such conditions they are not only able to delude the innocent and simple-minded but also men whose accomplishments have proven their intellects to be above the average. When a medium is subjected to conditions which are, to say the least, disconcerting, and the usual effects are not obtained, almost invariably the claim is made that there are antagonistic waves and that the “auras” are bad, and if, as often happens, the result is an unqualified exposé and the medium’s fall from power the followers of Spiritualism usually put forth a statement saying the medium overstepped the bounds in trying to give results and resorted to trickery, but that the majority of previous seances were genuine. Perhaps my ideas on the subject of how to conduct an investigation are wrong; I am fully convinced, however, that the only way to conduct a successful one is to get the committee together previous to the seance, discuss the expected manifestations, formulate some plan for concerted action and if possible assign each member some specific part as was done in the case of Palladino’s fall. These parts should be rehearsed and then when the seance is held there is a much greater possibility of the committee being able to judge intelligently. But when scientists report some feat of legerdemain as being abnormal simply because they cannot detect the deception, I think it is time to add to each investigating committee a successful and reputable professional mystifier, and I might add that all mediums hate to have a magician attend a seance. Of the many investigations, since the beginning of modern Spiritualism, I have selected a few of the most important and will try and show the reader the necessity of placing on investigating committees men who cannot be prejudiced or influenced by subdued lights or weird and mystifying sounds; men who use their God-given gift of reason to the best of their ability; men whose attention cannot be diverted by the medium; men whose brain cells are versatile and not overdeveloped in one particular direction; men who can pay strict attention to their commission and not be led astray by the glib-tongued medium’s misdirection. Then we will have real investigations and the world at large will benefit.
