Ray Hyman - Ganzfeld Experiments

Ganzfeld Experiments

While working at Stanford University and serving as the "Spook Chair'" Hyman decided that he would never be able to read all the literature concerning parapsychology that existed in the 1980s. He then asked parapsychologists "What is the best evidence for psi?" they nearly universally pointed to the Ganzfeld experiment. Hyman wrote to Charles Honorton and was sent 600 pages of information. Three years later Hyman's analysis led to the 1985 issue of the Journal of Parapsychology publishing Hyman's critiques. Hyman's conclusion "By themselves these experiments do not mean anything unless they can be replicated".

Famous quotes containing the word experiments:

    There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
    Denis Diderot (1713–1784)
