A recent study out of Ohio State University seems like one of those that the world really didn’t need. The researchers were exploring whether introducing science into the marketing would help sell chocolate chip cookies.

And to us who make a living in marketing, this is one of those things that might make us say “Duh, you needed research to tell us that? Of course you don’t use science to sell chocolate chip cookies!”

But bear with me, because if we keep asking why enough, we can come up with some answers that might surprise us.

So, what did the researchers learn? I quote,

“Specifically, since hedonic attributes are associated with warmth, the coldness associated with science is conceptually disfluent with the anticipated warmth of hedonic products and attributes, reducing product valuation.”

In other words – much simpler and fewer in number – science doesn’t help sell cookies. And it’s because our brains think differently about some things than other.

For example, a study published in the journal Computers in Human Behavior (Casado-Aranda, Sanchez-Fernandez and Garcia) found that when we’re exposed to “hedonic” ads – ads that appeal to pleasurable sensations – the parts of our brain that retrieve memories kicks in. This isn’t true when we see utilitarian ads. Predictably, we approach those ads as a problem to be solved and engage the parts of our brain that control working memory and the ability to focus our attention.

Essentially, these two advertising approaches take two different paths in our awareness, one takes the “thinking” path and one takes the “feeling” path. Or, as Nobel Laureate Daniel Kahneman would say, one takes the “thinking slow” path and one takes the “thinking fast” path.

Yet another study begins to show why this may be so. Let’s go back to chocolate chip cookies for a moment. When you smell a fresh baked cookie, it’s not just the sensory appeal “in the moment” that makes the cookie irresistible. It’s also the memories it brings back for you. We know that how things smell is a particularly effective way to trigger this connection with the past. Certain smells – like that of cookies just out of the oven – can be the shortest path between today and some childhood memory. These are called associative memories. And they’re a big part of “feeling” something rather than just “thinking” about it.

At the University of California – Irvine – Neuroscientists discovered a very specific type of neuron in our memory centers that oversee the creation of new associative memories. They’re called “fan cells” and it seems that these neurons are responsible for creating the link between new input and those emotion-inducing memories that we may have tucked away from our past. And – critically – it seems that dopamine is the key to linking the two. When our brains “smell” a potential reward, it kicks these fan cells into gear and our brain is bathed in the “warm fuzzies.” Lead research Kei Igarashi, said,

“We never expected that dopamine is involved in the memory circuit. However, when the evidence accumulated, it gradually became clear that dopamine is involved. These experiments were like a detective story for us, and we are excited about the results.”

Not surprisingly – as our first study found – introducing science into this whole process can be a bit of a buzz kill. It would be like inviting Bill Nye the Science Guy to teach you about quantum physics during your Saturday morning cuddle time.

All of this probably seems overwhelmingly academic to you. Selling something like chocolate chip cookies isn’t something that should take three different scientific studies and strapping several people inside a fMRI machine to explain. We should be able to rely on our guts, and our guts know that science has no place in a campaign built on an emotional appeal.

But there is a point to all this. Different marketing approaches are handled by different parts of the brain, and knowing that allows us to reinforce our marketing intuition with a better understanding of why we humans do the things we do.

Utilitarian appeals activate the parts of the brain that are front and center, the data crunching, evaluating and rational parts of our cognitive machinery.

Hedonic appeals probe the subterranean depths of our brains, unpacking memories and prodding emotions below the thresholds of us being conscious of the process. We respond viscerally – which literally means “from our guts”.

If we’re talking about selling chocolate chip cookies, we have moved about as far towards the hedonic end of the scale as we can. At the other end we would find something like motor oil – where scientific messaging such as “advanced formulation” or “proven engine protection” would be more persuasive. But almost all other products fall somewhere in between. They are a mix of hedonic and utilitarian factors. And we haven’t even factored in the most significant of all consumer considerations – risk and how to avoid it. Think how complex things would get in our brains if we were buying a new car!

Buying chocolate chip cookies might seem like a no brainer – because – well – it almost is. Beyond dosing our neural pathways with dopamine, our brains barely kick in when considering whether to grab a bag of Chips Ahoy on our next trip to the store. In fact, the last thing you want your brain to do when you’re craving chewy chocolate is to kick in. Then you would start considering things like caloric intake and how you should be cutting down on processed sugar. Chocolate chip cookies might be a no-brainer, but almost nothing else in the consumer world is that simple.

Marketing is relying more and more on data. But data is typically restricted to answering “who”, “what”, “when” and “where” questions. It’s studies like the ones I shared here that start to pick apart the “why” of marketing.

And when things get complex, asking “why” is exactly what we need to do.
