"A month ago we cited on this page some of the remarkable results achieved by Professor Rhine and his associates in Duke University from more than a hundred thousand tests to determine the existence of 'telepathy' and 'clairvoyance.' These results were summarized in the first two articles in Harpers Magazine. In the second which has now appeared, the author, E. H. Wright, attempts to summarize what has been learned, or what it seems reasonable to infer, regarding the exact nature of these 'extrasensory' modes of perception.

"The actual existence of telepathy and clairvoyance now seems to some scientists enormously probable as the result of Rhine's experiments. Various percipients were asked to name as many cards in a special pack as they could without looking at them and without other sensory access to them. About a score of men and women were discovered who could regularly name so many of the cards correctly that 'there was not one chance in many a million million of their having done their feats by luck or accident.'

"But how did they do them? These powers, assuming that they exist, do not seem to be sensory. There is no known organ for them. The experiments worked just as well at distances of several hundred miles as they did in the same room. These facts also dispose, in Mr. Wright's opinion, of the attempt to explain telepathy or clairvoyance through any physical theory of radiation. All known forms of radiant energy decline inversely as the square of the distance traversed. Telepathy and clairvoyance do not. But they do vary through physical causes as our other mental powers do. Contrary to widespread opinion, they do not improve when the percipient is asleep or half-asleep, but, on the contrary, when he is most wide-awake and alert. Rhine discovered that a narcotic will invariably lower a percipient's score, while a stimulant will always send it higher. The most reliable performer apparently cannot make a good score unless he tries to do his best.

"One conclusion that Wright draws with some confidence is that telepathy and clairvoyance are really one and the same gift. That is, the faculty that 'sees' a card face down on a table seems to be exactly the same one that 'reads' a thought residing only in another mind. There are several grounds for believing this. So far, for example, the two gifts have been found in every person who enjoys either of them. In every one so far the two have been of equal vigor, almost exactly. Screens, walls, distances, have no effect at all on either. Wright advances from this conclusion to express what he puts forward as no more than the mere 'hunch' that other extrasensory experiences, prophetic dreams, premonitions of disaster, and the like, may also prove to be part of the same faculty. The reader is not asked to accept any of these conclusions unless he finds it necessary, but the evidence that Rhine has piled up must remain impressive."
