I challenge you to read this book and not want to smack the author upside the head with it. A self-styled (read: non-degreed) marketing consultant, Lindstrom reveals himself to be an unapologetic biological determinist, attempting to convince his reader that with the advent of "neuro-marketing" a new age dawns where qualitative and quantitative methods (such as focus groups and surveys) are no longer of any use to marketers. Why? Because, as he asserts repeatedly, "the brain doesn't lie." That said, these neurological "truths" are really just a bunch of neurons firing beneath an MRI machine -- Lindstrom and his colleagues must interpret what they "really mean", thus calling into question the objectivity of the various "truths" he purports to uncover.
While a few of his theories are interesting, his uncritical acceptance of his results leads his reader to question them. Not once does he consider an alternate explanation for why we buy, even though often his assertions appear flat out wrong. Lindstrom often bases his hypotheses around people's lack of engagement with the external world, making blase assertions that he doesn't know why he buys Diesel jeans or an iPod, doesn't remember what he ate for breakfast, doesn't remember where he was last week, etc. With every sentence, one says to one's self, "Really?" I'm thoroughly unconvinced that it's merely a soup of instincts and experience that led me to choose an iPod over a Zune. Instead, this would be one of many, many examples where I had a conscious thought process that I can easily relate to you here: Microsoft hasn't had an original idea since Windows, and their clunky copycat offers neither the ease of use nor the lovely aesthetics of the Apple, while adding features I find utterly useless.
According to Lindstrom, that kind of choice takes place only unconsciously, as in his world I choose Jif peanut butter because my subconscious remembers that "choosy moms" choose it. Listen buddy, this is the real world, not an advertiser's fantasy: I'm going to choose the generic store brand, because it's least expensive. And yes, I'm going to think about my choice consciously while I do it, and spend more than a fraction of a second doing so. Hope your high-priced, name-brand clients enjoy your advice!
