This, to be frank, was my initial attitude—one of cautious interrogation and alertness to find signs of credulity, failure to appreciate the possibilities of chance, or lack of data by which the calculus of chance coincidence could be determined. But as I read on and studied the reproductions of drawings it became more and more evident that something besides chance had operated, that the conditions of many of the experiments had been excellently devised, and that where the conditions were relaxed Mr. Sinclair had been quite aware of the fact and was candid enough to admit it. He stated that such relaxation did not increase the percentage of success, and it certainly so appeared from the examples given. He reported the total number of experiments, and estimated the percentages of successes, partial successes, and failures. In 290 experiments, he made these percentages: successes, approximately 23 per cent; partial successes, 53 per cent; failures, 24 per cent. He admitted that judges probably would not agree upon exactly the same ratios. In fact I personally think that certain examples which he did not publish are better than a few which he did, but have not yet found reason to quarrel with his general estimates.

After considerable study of the book, becoming interested beyond any expectation, I wrote to Mr. Sinclair, stating that I had become favorably impressed, and making the somewhat audacious proposal that he should send me all the original materials for a fresh study by the individual standards and through the particular methods of a professional investigator. One can think of several reasons which might make the most honest and confident man hesitant to assent to such a proposal, coming from one whom he had never seen, and who might for all he knew have a set of prejudices which after all would cause him to make a lawyer’s argument against the case. I was really surprised that the bundle of materials was sent as quickly as it could be gotten together.[[2]]

Among the objects in mind were: (1) To study the materials in their strict chronological order, day by day. The mode of presentation in Mental Radio was to give some of the most striking results first, then many more that were more or less classified according to subjects and aspects. This is effective for popular reading but not satisfactory to the serious student. (2) To see if there were signs, in any part of the results, of profiting from normal knowledge, whether consciously or subconsciously acquired, of what the “agent” had drawn. Mr. Sinclair took this theory into account and quite decidedly killed it, but it was my duty to try it out anew by my own processes, with the same rigor shown in relation to my own wife and my daughter in The Psychic in the House. Later, in summary fashion, these tests will be set forth. (3) To try out other theories to account for the ratios and degrees of correspondence between “original drawings” and “reproductions” in the Sinclair experiments, such as involuntary whispering and chance coincidence. (4) To make a large number of guessing tests on the basis of the Sinclair originals, both as a means of deciding whether the “mere coincidence” theory is tenable (as aforesaid) and, if it should prove otherwise, in order to make a rough measurement of the disparity between telepathic results and those of guessing. (5) In the event that there appeared to be no reasonable escape from conclusion that telepathy is displayed by the material, to ascertain (a) whether the telepathic faculty with Mrs. Sinclair was constant, vacillating, progressively constant, or what; (b) whether the telepathic impressions came to her in the form of ideas, images, names or in more than one fashion; (c) whether any further hints as to the mental processes involved could be discerned or any particular pieces of information isolated which might be helpful in this field of study. (6) Finally, to urge readers to institute experiments of their own, and to give amateurs some directions as to procedure. If many could be persuaded to start “games” of this character with their friends, doubtless favorable subjects could be discovered or developed. Attention being called to these persons, series of tests could be made with them under conditions against which none of the old objections could be offered.[[3]]

The Sinclair experiments are treated first in this Bulletin, since they are its chief subject. The drier Historical Notes, presenting a sketch of the first steps in methodical research relating to alleged Thought-Transference, with summaries of some of the classic series of tests, particularly such as are based upon drawings, are relegated to Part Two. The more earnest and methodical students of such matters will prefer to read that first.

Mr. Upton Sinclair, about fifty-two years old when his book Mental Radio was issued, is, as everyone is supposed to know, one of the leading novelists of the United States. His stories are all, or nearly all, characterized by an intense purpose. To those who claim that art should be exercised only for art’s sake this may be obnoxious. But from the point of view of this examination of his book purporting to prove telepathy, the fact that his novels also attempt to prove something, on the basis of studies made by him, is quite in his favor.[[4]] Whether he has in fact proved the thesis of his respective tales is not within our province to determine; we do propose rigidly to analyze and review his claims to have proved telepathy.

Mr. Sinclair is a Socialist, and a very active and prominent one; he has been Socialist candidate for Congress in New Jersey and later in California, besides having been Socialist candidate for the United States Senate and for Governor in the latter-named State. Political prejudices or predilections should be strictly excluded from the minds of readers of the book or this review of it.[[5]] It is another gratifying indication that Mr. Sinclair was not deterred from publishing Mental Radio by the solicitations or irony of influential friends in his political group, for the scientific spirit is in part compounded of courage, honesty and candor.

Mrs. Sinclair, née Mary Craig Kimbrough, somewhere about forty-five years old when the experiments afterwards published took place, is the daughter of a retired judge, bank president, and planter of Mississippi.

The reader may judge of the quality of her mentality by reading Appendix 1. That is, in part, the reason that it is printed. It is a piece of writing by Mrs. Sinclair shortened according to permission given. Almost immediately after my suggestion that the experimental materials should be sent for examination, they were bundled up and sent, together with some stray scraps, among which was this unfinished piece of manuscript which, as it proved, the Sinclairs did not know had been included. In spots the composition may be a bit diffuse and repetitious, but the woman really thinks and reasons, which is more than many do.

There is in it a sincerity, earnestness and intensity of desire to know, which can hardly be counterfeited. Its writer fairly rivals Descartes in her determination to find some salient and secure spot from which to start in her quest. But in a manner she goes back farther than Descartes, at least she splits his ultimate in two. She is satisfied with “I am,” not because “I think,” but because “I am conscious of thinking”; but she does not so readily grant the “I think.” She wants to know, “Am I doing all the thinking I am conscious of?”

In fact, the document is so intense in its eagerness to penetrate the secret of personality in relation to its cosmic environment that it is almost febrile. At least in its first pages there is something pathological. To paint life with such dark colors and to dwell so upon its “discouragements” is not an indication of perfect health.
