It’s been over fifty years since James Vicary’s famus hoax,
where he claimed to have flashed subliminal messages to make movie theater
audiences crave popcorn and soft drinks.
Even after he admitted it was a complete fraud, certain marketers still
cling to the notion that it is possible to implant suggestions in the mind of a
buyer without him being aware of it, as if by will alone they can make this
notion true. Having recently read
Daryl Weber’s book on the subject, published just this year, it seems that the
myth still has its proponents.
The problem is that arguing about subliminal marketing is
like arguing about the existence of god.
Those who choose to believe can always find signs and wonders to support
their beliefs. Those who disagree are
in the position to make the impossible argument that something that does not
exist can be disproven, and the burden of having to do serious research to
depose claims that require nothing more than a casual assertion that can be
made without any diligence or effort at all.
My own position on the topic is entirely undecided. The assertion that it is possible to
communicate to the unconscious mind does have some undeniable facts, though the
connection between theory and practice seems a bit tenuous at times and there
is insufficient research to prove a definite connection. And just as with arguments over the existence
of the supernatural, I cannot accept something to be true simply because it is
not proven to be false – but at the same time cannot dismiss the possibility,
however specious and superficial the evidence.
The basis of subliminal or unconscious reception is quite
sound: the human mind has a limited cognitive capacity and our conscious
process of thought only focus on one thing at a time, though it may switch
itself between multiple threads of thought.
But at the same time we are aware of sense-data collected on the
periphery, and this is necessary as a survival mechanism: our primitive
ancestors may have been focused on foraging for berries in the underbrush, but
would become instantly aware of movement that suggests a potential predator; and
even modern man is capable of focusing on his cell phone while driving a car,
trusting in his peripheral awareness of the environment to alert him when a
collision is imminent, at least some of the time.
In order to have this awareness, we must be able to receive
and process information on the periphery of our mental focus. We are not attentive and do not have a
deliberate process of thought when we hear a hiss in the high grass – we are
instantly distracted and poise to react as a matter of reflex without conscious
thought, before we can analyze whether there is an actual threat. And by simple logic, anything that is outside
conscious thought must be taking place in the unconscious mind. The unconscious mind must receive sense
data, and must perform some primitive analysis, to come to the conclusion that
there might be a threat and we should poise ourselves to react. None of this can be denied.
However, questions arise as to how often this actually
occurs, how complex an analysis our unconscious mind is capable of making, and
whether being alerted or distracted invariably results in an actual action
being taken. These questions are
critical to determining whether unconscious awareness is at all applicable to
the higher orders of human behavior, such as making a decision to purchase and
taking action on that decision. And this
is where the theories of subliminal or unconscious marketing fall short.
While it cannot be denied that the unconscious mind can
cause us to shift our mental focus from one task to another, it does not
guarantee that we will perform that task.
In his study of emotional reactions, Charles Darwin concluded that
emotions “poise” us to take action, but it is the rational mind that determines
whether that action is taken. When we
sense danger on the periphery, we jerk our heads toward the suspected source,
our hearing and vision becomes more acute, our legs tense and our body twitches
to prepare to run away from it … but we do not actually run away until we have
given focus to the event that caused us to become distracted.
More modern and scientific investigation suggests that there
is a three-millisecond lead before the conscious mind takes over, which is the
reason we twitch and jerk, but often do not take action when we are startled. Consumer purchasing is a far more complex
sequence of behaviors than twitching when he hear a loud noise. It requires far more than three milliseconds
to perform and as such is subject to conscious thought and deliberate
decision-making. And it has not been
shown by any form of science that the thought patterns that arise when startled
persist beyond those three milliseconds.
However, I will give the cult of the subliminal this much: it seems entirely plausible that information
we receive from the periphery of sensation, without a conscious process of
thought, gives consumers a momentary impulse to take action (to make a
purchase). But it does not seem at all
plausible that the consumer will reliably act upon this impulse without further
thought. There is evidence that simply
planting the seed of an idea causes some small percentage of people to give a
sales proposal more deliberate thought, and some of them will decide to proceed
– and to that degree, there is some value in prodding a prospect and one might
expect to achieve negligible to marginal results. This may be particularly profitable in some
situations where the action can be completed in short order, but is by no means
a solid basis for a theory of marketing in general.
