Neuromarketing – aka ‘clutching at straws’

Brooke_Ward_nakedIn this guest posting, consumer psychologist Brooke Ward argues that marketers are getting too carried away by the potential of neuromarketing.

Neuromarketing involves the use of complex machinery to measure electrical activity in the brain and visualize, through computers, the specific areas that are activated when stimuli is shown to a participant.

Traditionally used for patients with severe brain damage or difficulties with brain functioning, many marketers are turning to these sophisticated technologies to help ‘read’ their consumers’ minds.

Understandably so, as neuromarketing cuts out the middle man – the consumer’s mouth – and appears to be an effective panacea for the old adage ‘people don’t say what they mean or mean what they say’.  

Sounds exciting. But before we declare the end of focus groups, quantitative analysis and market research as we know it – just how effective is neuromarketing?

Firstly, we need to remember that activity in the brain doesn’t necessarily equate to actual preference.

For example, an area may have been stimulated, but this is just as likely to be experienced unconsciously as consciously. This is problematic when we remember that we are relying on this piece of communication to change conscious opinions or preferences.

Consumers like to think they are rational, smart beings – and even if we believe that unconscious drivers control at least some of our thoughts and behaviour, we certainly can’t hang our hats on that being the case 100% of the time. Nor should we attempt to seduce the collective unconsciousness of consumers by appealing to needs they don’t even know about and may not be able to control.

Perhaps most importantly, brain activity also isn’t predictive of actual behaviour change.

In other words, it might not translate into action (and sales). As we know, a whole host of other factors play a part too: affordability, perceived value, accessibility, social acceptability, and memory, and many others. Of course, this criticism also applies to more traditional forms of market research (“would this make you buy X?”) but with neuromarketing the connection is even more tenuous, since participants aren’t actually aware of what their brains are telling us. In effect, we are seeing brain activity and presuming liking – then on top of that we are also presuming this will translate into action. In scientific terms, this is known as a ‘double-barrelled hypothesis’ (or in layman’s terms, ‘clutching at straws’).

Another central criticism of neuromarketing, and neuropsychology, is that it doesn’t actually explain anything. When we see activity or unusual structure in the brain, our natural reaction is to attribute causality. Yet the reasons behind a flurry of activity can’t be definitively explained – some third, unknown variable may be the real cause. Perhaps we are seeing the bark but not the dog.

Why does this matter? If our participants’ brains show higher levels of activity for one piece of stimuli, and slightly lower for another, we can only speculate as to why this is so. Without participants’ articulation, we can be pretty certain that we wont be able to explain, let alone replicate, our success.

As well, most parts of the brain are multi-taskers – for example, the amygdala processes rewards, but is also responsible for fear. So exactly how has our advertising stimuli been perceived by the brain? Something that will leave us feeling warm and fuzzy, or something to run screaming from?

The ‘newness’ of this technology again leaves us with no option but to play guessing games. Even more problematically, sometimes the only outcome of a neuropsychological test is the supposed effect on memory. As we know, recall alone does not a loyal consumer make – and since longitudinal follow-up studies are rarely utilized, we can again only guess at how long measured effects will last anyway.

Finally, neuromarketing is a huge investment of both time and money. Testing one ad on 20 participants will set you back tens or even hundreds of thousands of dollars including researcher time, equipment and facility hire, and the participants themselves.

My advice for developing better insights and a deeper understanding of what will work, is to talk to your consumers, observe their actual behaviour, and develop proven frameworks for understanding what drives and changes behaviour. None of which can achieved by attempting to excavate the unconscious.
