IX
Subconscious Persuasion
In a footnote appended to the 1919 edition of his book, The
Interpretation of Dreams, 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; or
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 not been noted by the subject provided
material for the construction of the dream.'
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 'pre-conscious
perception' to the Journal of the American Psychoanalytic Association. Meanwhile the academic psychologists have not
been idle. Confirming Poetzl's findings, their studies have shown that people
actually see and hear a great deal more than they consciously know they see and
hear without knowing it is recorded by the subconscious mind and may affect
their conscious thoughts, feelings and behaviour.
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 pre-conscious 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, by called
the Age of Television Addiction, the Age of Soap Opera, the
Age of the Disc 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
theatres during (not before or after) the programme. '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 such 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 theatre, the command to
buy more popcorn was said to have resulted in a fifty 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 theatre 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
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 odours 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 apartheid to
integration, and with any kind of person, from a Mahatma Gandhi to a Senator
McCarthy. Years ago, in
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 Institution 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 be 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
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

Poetzl
was one of the portents which, when writing Brave New World, I somehow
overlooked. There is no reference in my
fable to subliminal projection. It is a
mistake of omission which, if I were to rewrite the book today, I should most
certainly correct.
