Later, since Mr. Sinclair was very busy writing his novel “Boston” and disliked the interruptions, he ceased (about midway of the whole lot, he tells us) to enclose his drawings in envelopes and to watch his wife’s work. Had this been the case throughout, any report based on such “experiments” would not, scientifically speaking, be worth the paper it was written on. As it is, I should be quite willing to rest the whole case on the 120 or more guarded experiments covered by the last two paragraphs. More than that, I would be willing to rest it upon the 33 experiments conducted with the participants separated by the length of a room, thirty feet and a closed door, or thirty miles. But the logic of the situation is entirely against the assumption that fraud was used any more after it became easily possible than before, when it would have been possible only by the connivance of various conspirators. Let us see. 1. If advantage were to be taken of the relaxation of precautions it would plainly be but for one purpose, to increase the number or the excellence of favorable results, or both. But neither the number nor the excellence of favorable results was enhanced. On the contrary, not at once, but by a general though irregular decline, the results deteriorated. The last 120 experiments of the period covered by the book brought about half again as many complete Failures as the first 120 had done. Mr. Sinclair reminds us that “Series No. 6 which was carefully sealed up, produced 4 complete Successes, 5 Partial Successes, and no Failures; whereas Series 21, which was not put in envelopes at all, produced no complete Successes, 3 Partial Successes, and 6 Failures.” The declension, which has been noted in experiments with other persons, continued, in irregular fashion, after the period of the book. We have already noted that the worst consecutive run of 27 experiments during that last period yielded 19 Failures, while the worst consecutive run of experiments during the period of the book yielded but 10 Failures. Nor is there ever again, after precautions were relaxed, a single consecutive run of seven experiments with quite such astounding results as those of the first seven experiments of all, with “Bob,” at some thirty miles distance in an air-line. Hence the percipient took no advantage of the relaxation of conditions, or she did so to make her work poorer on the average than it had been, which is against human nature and practically inconceivable.
