| A
U.S. News and World Report cover story a few weeks
ago explored the fascinating field of neuroscience, the
study of the "anatomy, physiology, biochemistry,
or molecular biology of nerves and nervous tissue and
especially with their relation to behavior and learning"
and the growing list of its applications, including business,
marketing in particular. The article discussed the burgeoning
popularity of neuromarketing and neuroscience-like techniques
such as the Zaltman Metaphor Elicitation Technique (ZMET)
as a direct response to the frustrations most marketers
have with the most commonly-used research technique in
American business and ad agencies for gathering information
about buyer reactions to campaigns and new products: the
focus group.
"Almost
every focus group throws up someone more vocal and bossy,
who either inspires others to follow or react against
[them] or both," complained a senior fellow at
the London Business School. Thus marketers aren't necessarily
getting truthful answers from participants and cannot
get to what potential buyers really think as opposed
to what they say when a moderator asks them.
Other
marketers also have a beef with survey research toolsquestionnaires
and one-on-one interviewsalleging that it's becoming
increasingly difficult to get accurate marketing data.
People give what they believe to be the socially-acceptable
answer, critics complain. They say they watch PBS, listen
to NPR, and read The Economist, Foreign Affairs,
and the Wall Street Journal, for instance, when
they really watch Brady Bunch reruns on Nickelodeon,
listen to pop radio, and read People. They say
that it's not important that the car they drive impress
their neighbors or that a product carry a low price
tag, when these can be highly motivating to a purchase
decision. The advantage to an MRI or brain scan machine,
neuromarketing proponents say, is that it doesn't lieit
objectively measures a person's reaction by monitoring
brain response. By tapping into the unconscious mind,
you get at what's really driving purchase decisions
or which ad is the most appealing with no concern about
the honesty of a research participant's answers.
This
all sounds very cutting-edge and innovative, and if
the focus group is the standard of comparison, it sure
is. But in terms of improving the health of marketing
programs, we say neuromarketing is an unlikely contributor.
It is to twenty-first century marketing what blood letting
and electric shock therapy were to nineteenth century
medicine. It sounds really cool with scientific underpinnings,
but it has many of the same drawbacks as focus groups.
And in this respect, its problems are similar to psycho-physiological
alternatives to self-report data, such as pupil dilation
and galvanic skin response methodologies which were
hot on the 1960s.
First
of all, if we're talking MRI brain scans, at a certain
point we have to believe it becomes cost prohibitive
to recruit more research participants. And you can't
project the data gathered from the brains of 12-50 individuals
onto a larger populationit's not representative
by any means. While it might be more reliable than a
focus group when it comes to telling you that something
is stimulating or appealing, brain scans can't tell
you what exactly was stimulating, nor can it tell you
why something wasn't (so you could fix it). "This
is a descriptive techniqueit describes what the
brain is doing," explained Gemma Calvert, the cofounder
of neuromarketing firm Neurosense. Meanwhile, ZMET can
theoretically get you to what buyers think about your
brand, but what if you want to change what they think?
Just as with focus groups, neither offers prescriptive
information. Same as focus groups, brain scans don't
improve the predictive certitude that a buyer will purchase
a new brand, product, or service. The ZMET method appears
to draw conclusions from a thorough review by a ZMET
practitioner of transcripts of interviews and collages
of magazine cut-outs pasted together by research subjects.
As a result, the interpretation of results might differ
depending on who's doing the interpretingas in
a focus group or Rorschach test, one person can draw
one conclusion while someone else comes to a different
one after seeing the same output.
Focus
groups aside, the knocks against quantitative research
methods aren't new. We've said for years you don't find
out what's important to buyers by asking themwe'd
agree you get socially-acceptable answersand that
people exaggerate the probability they will buy a new
product or service. But there are clever, reliable,
and proven quantitative research techniques that enable
you to get at what's truly motivating; what people read,
watch, and listen to; and for evaluating the true likelihood
of purchase of a new product or service. In our three
decades of experience, we have found that people are
no more likely to lie or exaggerate today than they
were 10 years ago and, as a result, any good consulting
firm has the means to control for respondent prevarication
(a.k.a., response error).
What's
more, we fail to see that brain scans and ZMET have
any application to most key areas of strategy development.
They offer little in the way of key insights into the
profitability of different sets of buyers in a market
or what media channels they use. Developing a compelling
positioning strategy requires understanding buyer motivations,
but also what the perceptions of the brand are relative
to competitors and consideration of the feasibility
of different optionsto our knowledge brain scans
and ZMET don't offer this kind of supplemental analysis.
Advertising creative strategy should be based on the
positioning, not generated on its own based on what
pictures a ZMET research participant cut out of a magazine.
You can't consider hundreds of thousands of different
product configurations to identify the most profitablebrain
scans and ZMET don't appear to take profitability into
account.
Brain
scans are interesting. ZMET certainly taps into creative
thinking and attention to understanding the perceptions
of your brand in your customers mind (instead of your
own). And we can't help but delight in the fact that
neuroscience and out-of-the-box thinkers like Zaltman
are leading the charge away from focus groups. But we
have to caution that the trappings of scienceelectrodes,
MRIs, probing the unconscious, measuring pupil dilation
and contraction, and the electro-sensitivity of the
skindoesn't make a marketing research method more
scientific or actionable. While perhaps better than
the average focus group, neuromarketing doesn't represent
a giant leap forward for marketing research.
