In
the late 1950s and early ‘60s, Cambridge-based parapsychologist AD
Cornell conducted a set of experiments designed to study how seeing a
ghost affects people. Cornell believed in ghosts, but that was
tangential to the experiments. The first experiment had Cornell himself
dressing as a ghost with a sheet pulled over his head, appearing and
disappearing behind mounds in a cow pasture, while his assistants
observed passers-by. The second experiment was in an urban cemetery. He
even had assistants standing around ready to respond in case of
emergency.
Such precautions proved unnecessary.
Between pedestrians, cyclists, and motorists, Cornell estimated that
approximately 142 people would have been able to witness the apparition,
but only four gave clear indications of having seen it. Under
questioning, it emerged that none of them believed they had witnessed
anything remotely paranormal. The first person described the apparition
as “a man dressed as a woman, who surely must be mad” another assumed
that it was “an art student walking about in a blanket”. Two witnesses,
when questioned together, did realise that the Experimental Apparition
was probably intended to simulate a paranormal event, but went on to
note that the effect was spoiled because “we could see his legs and feet
and knew it was a man dressed in some white garment”.
Did
Cornell give up because he obviously did not make a good ghost? No, he
conducted the third experiment in a movie theater showing an X-rated
film. He figured people would pay more attention there, especially if he
stepped right in front of the screen (and also there would be no
children to be traumatized). You can guess how that stunt turned out.
Nevertheless, Cornell published his findings, which indirectly led to
new experiments by other, more rational scientists to study human
attention and perception.
