IX Subconscious Persuasion
In a footnote appended to the 1919 edition of his book,
, Sigmund Freud called attention to the work of Dr. Poetzl, an Austrian neurologist, who had recently published a paper describing his experiments with the tachistoscope. (The tachistoscope is an instrument that comes in two forms — a viewing box, into which the subject looks at an image that is exposed for a small fraction of a second; a magic lantern with a high-speed shutter, capable of projecting an image very briefly upon a screen.) In these experiments Poetzl required the subjects to make a drawing of what they had consciously noted of a picture exposed to their view in a tachistoscope. . . . He then turned his attention to the dreams dreamed by the subjects during the following night and required them once more to make drawings of appropriate portions of these dreams. It was shown unmistakably that those details of the exposed picture which had
With various modifications and refinements Poetzl's experiments have been repeated several times, most recently by Dr. Charles Fisher, who has contributed three excellent papers on the subject of dreams and "preconscious perception" to the
Pure science does not remain pure indefinitely. Sooner or later it is apt to turn into applied science and finally into technology. Theory modulates into industrial practice, knowledge becomes power, formulas and laboratory experiments undergo a metamorphosis, and emerge as the H-bomb. In the present case, Poetzl's nice little piece of pure science, and all the other nice little pieces of pure science in the field of preconscious perception, retained their pristine purity for a surprisingly long time. Then, in the early autumn of 1957, exactly forty years after the publication of Poetzl's original paper, it was announced that their purity was a thing of the past; they had been applied, they had entered the realm of technology. The announcement made a considerable stir, and was talked and written about all over the civilized world. And no wonder; for the new technique of "subliminal projection," as it was called, was intimately associated with mass entertainment, and in the life of civilized human beings mass entertainment now plays a part comparable to that played in the Middle Ages by religion. Our epoch has been given many nicknames — the Age of Anxiety, the Atomic Age, the Space Age. It might, with equally good reason, be called the Age of Television Addiction, the Age of Soap Opera, the Age of the Disk Jockey. In such an age the announcement that Poetzl's pure science had been applied in the form of a technique of subliminal projection could not fail to arouse the most intense interest among the world's mass entertainees. For the new technique was aimed directly at them, and its purpose was to manipulate their minds without their being aware of what was being done to them. By means of specially designed tachistoscopes words or images were to be flashed for a millisecond or less upon the screens of television sets and motion picture theaters during (not before or after) the program. "Drink Coca-Cola" or "Light up a Camel" would be superimposed upon the lovers' embrace, the tears of the broken-hearted mother, and the optic nerves of the viewers would record these secret messages, their subconscious minds would respond to them and in due course they would consciously feel a craving for soda pop and tobacco. And meanwhile other secret messages would be whispered too softly, or squeaked too shrilly, for conscious hearing. Consciously the listener might be paying attention to some phrase as "Darling, I love you"; but subliminally, beneath the threshold of awareness, his incredibly sensitive ears and his subconscious mind would be taking in the latest good news about deodorants and laxatives.
Does this kind of commercial propaganda really work? The evidence produced by the commercial firm that first unveiled a technique for subliminal projection was vague and, from a scientific point of view, very unsatisfactory. Repeated at regular intervals during the showing of a picture in a movie theater, the command to buy more popcorn was said to have resulted in a 50 per cent increase in popcorn sales during the intermission. But a single experiment proves very little. Moreover, this particular experiment was poorly set up. There were no controls and no attempt was made to allow for the many variables that undoubtedly affect the consumption of popcorn by a theater audience. And anyhow was this the most effective way of applying the knowledge accumulated over the years by the scientific investigators of subconscious perception? Was it intrinsically probable that, by merely flashing the name of a product and a command to buy it, you would be able to break down sales resistance and recruit new customers? The answer to both these questions is pretty obviously in the negative. But this does not mean, of course, that the findings of the neurologists and psychologists are without any practical importance. Skilfully applied, Poetzl's nice little piece of pure science might well become a powerful instrument for the manipulation of unsuspecting minds.
For a few suggestive hints let us now turn from the popcorn vendors to those who, with less noise but more imagination and better methods, have been experimenting in the same field. In Britain, where the process of manipulating minds below the level of consciousness is known as "strobonic injection," investigators have stressed the practical importance of creating the right psychological conditions for subconscious persuasion. A suggestion above the threshold of awareness is more likely to take effect when the recipient is in a light hypnotic trance, under the influence of certain drugs, or has been debilitated by illness, starvation, or any kind of physical or emotional stress. But what is true for suggestions above the threshold of consciousness is also true for suggestions beneath that threshold. In a word, the lower the level of a person's psychological resistance, the greater will be the effectiveness of strobonically injected suggestions. The scientific dictator of tomorrow will set up his whispering machines and subliminal projectors in schools and hospitals (children and the sick are highly suggestible), and in all public places where audiences can be given a preliminary softening up by suggestibility-increasing oratory or rituals.
From the conditions under which we may expect subliminal suggestion to be effective we now pass to the suggestions themselves. In what terms should the propagandist address himself to his victims' subconscious minds? Direct commands ("Buy popcorn" or "Vote for Jones") and unqualified statements ("Socialism stinks" or "X's toothpaste cures halitosis") are likely to take effect only upon those minds that are already partial to Jones and popcorn, already alive to the dangers of body odors and the public ownership of the means of production. But to strengthen existing faith is not enough; the propagandist, if he is worth his salt, must create new faith, must know how to bring the indifferent and the undecided over to his side, must be able to mollify and perhaps even convert the hostile. To subliminal assertion and command he knows that he must add subliminal persuasion.
Above the threshold of awareness, one of the most effective methods of non-rational persuasion is what may be called persuasion-by-association. The propagandist arbitrarily associates his chosen product, candidate or cause with some idea, some image of a person or thing which most people, in a given culture, unquestioningly regard as good. Thus, in a selling campaign female beauty may be arbitrarily associated with anything from a bulldozer to a diuretic; in a political campaign patriotism may be associated with any cause from
to integration, and with any kind of person, from a Mahatma Gandhi to a Senator McCarthy. Years ago, in Central America, I observed an example of persuasion-by-association which filled me with an appalled admiration for the men who had devised it. In the mountains of Guatemala the only imported art works are the colored calendars distributed free of charge by the foreign companies whose products are sold to the Indians. The American calendars showed pictures of dogs, of landscapes, of young women in a state of partial nudity. But to the Indian dogs are merely utilitarian objects, landscapes are what he sees only too much of, every day of his life, and half-naked blondes are uninteresting, perhaps a little repulsive. American calendars were, in consequence, far less popular than German calendars; for the German advertisers had taken the trouble to find out what the Indians valued and were interested in. I remember in particular one masterpiece of commercial propaganda. It was a calendar put out by a manufacturer of aspirin. At the bottom of the picture one saw the familiar trademark on the familiar bottle of white tablets. Above it were no snow scenes or autumnal woods, no cocker spaniels or bosomy chorus girls. No — the wily Germans had associated their pain-relievers with a brightly colored and extremely lifelike picture of the Holy Trinity sitting on a cumulus cloud and surrounded by St. Joseph, the Virgin Mary, assorted saints and a large number of angels. The miraculous virtues of acetyl salicylic acid were thus guaranteed, in the Indians' simple and deeply religious minds, by God the Father and the entire heavenly host.
This kind of persuasion-by-association is something to which the techniques of subliminal projection seem to lend themselves particularly well. In a series of experiments carried out at New York University, under the auspices of the National Institute of Health, it was found that a person's feelings about some consciously seen image could be modified by associating it, on the subconscious level, with another image, or, better still, with value-bearing words. Thus, when associated, on the subconscious level, with the word "happy," a blank expressionless face would seem to the observer to smile, to look friendly, amiable, outgoing. When the same face was associated, also on the subconscious level, with the word "angry," it took on a forbidding expression, and seemed to the observer to have become hostile and disagreeable. (To a group of young women, it also came to seem very masculine — whereas when it was associated with "happy," they saw the face as belonging to a member of their own sex. Fathers and husbands, please take note.) For the commercial and political propagandist, these findings, it is obvious, are highly significant. If he can put his victims into a state of abnormally high suggestibility, if he can show them, while they are in that state, the thing, the person or, through a symbol, the cause he has to sell, and if, on the subconscious level, he can associate this thing, person or symbol with some value-bearing word or image, he may be able to modify their feelings and opinions without their having any idea of what he is doing. It should be possible, according to an enterprising commercial group in New Orleans, to enhance the entertainment value of films and television plays by using this technique. People like to feel strong emotions and therefore enjoy tragedies, thrillers, murder mysteries and tales of passion. The dramatization of a fight or an embrace produces strong emotions in the spectators. It might produce even stronger emotions if it were associated, on the subconscious level, with appropriate words or symbols. For example, in the film version of
In the light of what has been said about persuasion-by-association and the enhancement of emotions by subliminal suggestion, let us try to imagine what the political meeting of tomorrow will be like. The candidate (if there is still a question of candidates), or the appointed representative of the ruling oligarchy, will make his speech for all to hear. Meanwhile the tachistoscopes, the whispering and squeaking machines, the projectors of images so dim that only the subconscious mind can respond to them, will be reinforcing what he says by systematically associating the man and his cause with positively charged words and hallowed images, and by strobonically injecting negatively charged words and odious symbols whenever he mentions the enemies of the State or the Party. In the United States brief flashes of Abraham Lincoln and the words "government by the people" will be projected upon the rostrum. In Russia the speaker will, of course, be associated with glimpses of Lenin, with the words "people's democracy," with the prophetic beard of Father Marx. Because all this is still safely in the future, we can afford to smile. Ten or twenty years from now, it will probably seem a good deal less amusing. For what is now merely science fiction will have become everyday political fact.
Poetzl was one of the portents which, when writing
X Hypnopaedia
In the late autumn of 1957 the Woodland Road Camp, a penal institution in Tulare County, California, became the scene of a curious and interesting experiment. Miniature loud-speakers were placed under the pillows of a group of prisoners who had volunteered to act as psychological guinea pigs. Each of these pillow speakers was hooked up to a phonograph in the Warden's office. Every hour throughout the night an inspirational whisper repeated a brief homily on "the principles of moral living." Waking at midnight, a prisoner might hear this still small voice extolling the cardinal virtues or murmuring, on behalf of his own Better Self, "I am filled with love and compassion for all, so help me God."
After reading about the Woodland Road Camp, I turned to the second chapter of

our suggestions — suggestions from the State. . . ."
To date, so far as I know, hypnopaedic suggestions have been given by no state more formidable than Tulare County, and the nature of Tulare's hypnopaedic suggestions to lawbreakers is unexceptionable. If only all of us, and not only the inmates of the Woodland Road Camp, could be effectively filled, during our sleep, with love and compassion for all! No, it is not the message conveyed by the inspirational whisper that one objects to; it is the principle of sleep-teaching by governmental agencies. Is hypnopaedia the sort of instrument that officials, delegated to exercise authority in a democratic society, ought to be allowed to use at their discretion? In the present instance they are using it only on volunteers and with the best intentions. But there is no guarantee that in other cases the intentions will be good or the indoctrination on a voluntary basis. Any law or social arrangement which makes it possible for officials to be led into temptation is bad. Any law or arrangement which preserves them from being tempted to abuse their delegated power for their own advantage, or for the benefit of the State or of some political, economic or ecclesiastical organization, is good. Hypnopaedia, if it is effective, would be a tremendously powerful instrument in the hands of anyone in a position to impose suggestions upon a captive audience. A democratic society is a society dedicated to the proposition that power is often abused and should therefore be entrusted to officials only in limited amounts and for limited periods of time. In such a society, the use of hypnopaedia by officials should be regulated by law — that is, of course, if hypnopaedia is genuinely an instrument of power. But is it in fact an instrument of power? Will it work now as well as I imagined it working in the seventh century A.F.? Let us examine the evidence.
