THE
SECOND TRUTH IN ADVERTISING
Media Chads and Other Recounts
Those
of us in advertising (or politics) are concerned with truth - both
kinds. There is the side of truth that the consumer sees, reads
or hears in the advertisement itself. This is the public truth (or
sometimes exaggeration) that has been much written about and self-regulated.
It is what we commonly call "truth in advertising." Then there is
the other truth.
We
practioners grapple with the other truth every day. That truth relates
to the underlying principles we employ to read the marketplace,
construct strategies and deploy advertising. It is the truth that
advertising research has tried to reflect from the beginning. The
problem is, no matter how truthful we try to be, the reflection
of this truth is often seriously distorted. The truth is… we only
have an idea of how serious the flaws are. What we have here is
one giant media chad and it is not confined to a few counties or
one state or even half the population that registered to vote. It
relates to the entire US population, over the age of two, that buys,
reads, watches, listens or breathes and is surveyed. In other words
the surveys we depend on are seriously flawed.
Chaos
in Media
In
the early 1960s, Edward Lorenz, a mathematician at MIT, had begun
to codify the progress of weather patterns on his computer. He reasoned
that if you could capture these patterns in equations, you could
develop a fool-proof method of measuring and predicting the weather.
The problem was, he rounded his equations off to the nearest thousandth
(which is what weather satellites did). It turns out that he really
would have to not round off at all, because even a slight variation
beyond that rounding would create vastly different results as more
and more time passed. This was a little like starting two overlaying
straight lines at the same point and heading them off in the same
direction, only one of the lines aims infinitesimally more to one
way or the other. The further you move away from the starting point,
the more the lines diverge. So if a current condition wasn't codified
numerically to an infinite number of places, he could not predict
the weather a month or even a week from now.
This
diverging phenomenon became known as the butterfly effect. A butterfly
flaps its wings in China and if it is not recorded, eventually that
puff of air and all others like and unlike it would create vastly
different weather patterns as time passed, like diverging lines.
This discovery led to the science of Chaos, which is both a branch
of mathematics and seemingly the constant state we live in today,
professionally and personally. The surveys we use to measure all
manner of buying goods and consuming media are subject to the whims
of Chaos. Moreover, consumer behavior could not be plotted on a
straight line. There is nothing linear about how people buy, watch,
read and listen.
Sampling
Error
If
that weren't enough, sampling error plays a role in the fragility
of surveys as well. For example, if one wanted almost certainty
in their sample results, a cost of $75 to buy a rating point of
a fringe television schedule in a medium sized market against adults
in is really between $15 and $135 (a swing of +/-$60). Yet buyers
negotiate for and are held accountable for…pennies.
Reconsider,
Don't Recount
No
matter how many times we count these things, the problem doesn't
go away, so now what? For one thing we can stop pretending that
we can measure public behavior so precisely. No matter how many
chads (intentions) and recounts (sampling error) and fine-tuning
(sample weighting) are done with research, we need to recognize
that this is a complex country. If our system for electing a President
is flawed on an essentially simple A/B choice, imagine how many
chads would be lying on the floor and how many recounts would be
necessary to get consumer behavior right. At some point, every practitioner
must "trust" their own experience and that of others who have been
hired to interpret information and make decisions and to know what
they are doing. After all, expert experience is born out of thousands
of surveys taken over time and the results that eventuated. Reading
the market, is still the province of experts and we need to reconsider
the standards to which we hold them accountable, while we respect
the role of research.
