The absence of proven fraud is not the same as proof of a genuine phenomenon, and levitation claims carry a particular evidentiary burden: unlike a statistical psi effect, a levitation either happened as described, unsupported, in a room whose exits and furnishings were fully controlled, or it did not, and no surviving account of Home's sittings meets that standard of control by modern experimental design. Home performed under conditions he substantially influenced, choosing the room, the lighting, and often the timing, and refused formal tests proposed by some skeptics; several later historians and psychical researchers have suggested plausible mundane explanations for the window-to-window account specifically, including doubts about the precision of witnesses' memory of the room's layout, though no single explanation has been proven either.
No twentieth or twenty-first century levitation claim, whether from spiritualist mediumship, contemporary meditation-based "yogic flying" demonstrations, or stage psychokinesis performers, has been recorded under laboratory conditions with instruments capable of ruling out concealed support, and levitation remains, uniquely among the claims in this atlas, a case where the best-documented historical instance was never disproven and also never confirmed by a method that would satisfy a modern controlled test.
