Neuroscience in marketing, often referred to as "neuromarketing," is a field that applies principles from neuroscience to understand consumer behavior and improve marketing strategies. Here's a background overview to help you get started:

What is Neuromarketing?

Neuromarketing is the application of neuroscience methods to analyze and understand human behavior related to markets and marketing exchanges. But how can we simplify that definition? First, let’s look at what neuroscience is. Neuroscientists believe that everything we do, everything we feel, and how we react can be measured and decoded by the neural activity in our brain. This doesn’t just apply to our conscious, but our subconscious as well. When we bring marketing into the equation, it’s using that data to improve marketing strategy and get to the core of what makes a person remember and like a product. By studying the brain's responses to marketing stimuli, businesses can better understand consumers' decision-making processes.

This is still a relatively new field of study which leaves brands wondering, does it work?

The Brain and Buying Behavior

The human brain processes vast amounts of information, much of it unconsciously. Several areas of the brain play crucial roles in decision-making. Neuromarketing is applying how these areas affect our buying behavior, and how companies can capitalize on what our brains “like”.

The Prefrontal Cortex: Involved in planning, decision-making, focusing, and moderating social behavior. When it comes to buying anything, this part of our brain helps us decide the consequence of buying it, and remember, a consequence doesn’t need to be bad. Our prefrontal cortex helps us see the use of a product and then decide if the value is there. We visualize how often we’ll use it, and if it will genuinely make our life easier or be used often. When it comes to marketing, this area is what helps us focus on advertising to get all the info to help us make that final buying decision. 

The Amygdala: Plays a role in processing emotions and is particularly involved in the formation of emotional memories. This is important because it helps us apply our past experiences, or more accurately how we felt about past experiences, to current situations. This can be as simple as remembering how a product made us feel, which can influence whether we buy anything from that brand again. It can also be more complex, like how certain imagery in an advertisement makes us feel and whether that makes us want to buy that product. 

The Nucleus Accumbens: Often referred to as the brain's "pleasure center." It's activated during pleasurable experiences and is closely linked to reward-seeking behavior. While a small part of the brain, it can cause us to overrule the other parts responsible for sound decision-making. This is the part that lights up, so to speak, when we make impulse buys.

Tools of the Trade

Neuroscience isn’t just asking people how they feel, scientists have tools that can show exactly what our brain is doing in response to stimuli. Neuromarketing employs several tools and techniques to study the brain's response to marketing stimuli in particular:

Functional Magnetic Resonance Imaging (fMRI): Measures and maps the brain's activity both conscious and unconscious. Unlike other brain imaging methods, fMRI doesn't involve radiation. With traditional market research, you only hear the conscious reasoning a participant gives toward an ad or product. With this brain imaging, we get a full picture, including emotions and influences the participant themselves isn’t fully aware of.

Electroencephalography (EEG): Records electrical activity in the brain known as brain waves. It's often used to measure real-time responses to stimuli, like advertisements. These brain waves help us peak into someone's subconscious. When paired with a participant's conscious response, we can see what is really causing them to like or dislike a product.

Eye Tracking: Monitors where the eyes are focused and how they move, providing insights into what captures attention. This is probably the most obvious of how scientists use this in marketing research. Eye tracking catches where we look during a commercial, or what part of an ad or packaging catches our attention first.

Galvanic Skin Response: Measures changes in the skin's ability to conduct electricity, which can indicate emotional arousal. Most consumers are familiar with this technology as it is what is used in smartwatches. When combined with the eye tracking mentioned previously, it can add extra insight. Eye tracking just measures what someone is looking at but not how they are reacting to that. Whereas the galvanic skin response measures the opposite. Combining these two can give a full picture without the intense testing tools needed for fMRI or EEG.

Applications in Marketing

Neuromarketing can provide insights into various areas of marketing that we touched on slightly above. Marketing research is much more than just showing participants a commercial, however. Here are some other areas where neuromarketing helps:

Product Design and Packaging: Understanding which designs resonate more with consumers on a neurological level. Neuromarketing research can show us what areas of design a consumer's eye is drawn to, and how it’s making them feel. Eye tracking can also help brands know if their product is standing out on a shelf with its competitors. 

Advertising: Determining which ads are most effective in terms of attention, emotion, and memory. This is what most people think of when we say marketing research. Brain mapping allows us to get to the unconscious emotions that make us want to buy. When paired with a participant's conscious response, we also get insight for future marketing research on what kind of brain waves make people think.

Pricing Strategies: Analyzing how consumers perceive value and how pricing can trigger emotional responses. A customer might love a product, but not for the price listed. There are plenty of market research charts that show the best price for a product to garner the most purchases. Neuromarketing research can tell us exactly where that threshold is and why it’s there.

Website and User Experience (UX) Design: Optimizing websites for maximum engagement and conversion based on how users' brains navigate and respond to online content. We can see all areas of neuromarketing research at play here when interacting with a site. From where a person is looking, what they are relating to memories, and even how frustrating an aspect of the site might be. Brands might even be able to catch the exact problem area as to why people visit but ultimately don’t buy.

Ethical Considerations

Neuromarketing has its critics. Concerns often revolve around the idea that marketers could manipulate consumers, bypassing rational thought processes to influence buying behavior. This isn’t just mindless criticism, as we mentioned earlier, one of the key parts of the brain that is researched specifically deals with impulse control. Since neuromarketers admit that a good majority of our outward thoughts and actions stem from unconscious stimuli, we might not even be aware we’re being influenced. The other criticism of neuromarketing however involves its effectiveness. Research has shown that a person's outward response and ultimate decision aren’t always congruent with their unconscious brain response. Meaning, that if we just look at what the brain is telling us, researchers might gain false conclusions. Of course, even without neuromarketing research, we are still being influenced by companies. That’s just part of the nature of thought. So while companies might be gaining more insight, it isn’t the first time they have tried to “hack our brains” into buying a product. Ultimately, there is still a lot more to what makes us buy than what any amount of current research can tell us. As with all powerful tools though, there's a responsibility to use neuromarketing ethically and transparently.

The Future of Neuromarketing

As technology advances, so will the tools and methods used in neuromarketing. Virtual reality (VR) and augmented reality (AR) are emerging as new platforms to study consumer behavior in immersive environments. The advancement of AI also allows researchers to sort large amounts of data quicker than ever. As we said above, this isn’t the first time marketing has tried to influence our subconscious. This new level of research however gives us even more detail into how a person reacts and more importantly, why. Additionally, as we gain a deeper understanding of the brain, marketers will be better equipped to create campaigns that resonate on a profound, human level.

Neuromarketing offers a fascinating intersection of science and business, providing insights into the human brain's intricate workings and how it drives our buying decisions. As with all research methods, it's essential to approach its findings with a balanced perspective, considering both the science and the broader implications of its applications.
