Why you won’t find Ehrenberg-Bass talking about mass awareness
The popularity of the Ehrenberg-Bass Institute's work means its complex ideas are often reduced to sound bites. Associate Professor Rachel Kennedy explains how the institute's messages can be misinterpreted.
Yesterday, John Douglas wrote an opinion piece entitled: The problem with blindly jumping on the Ehrenberg-Bass bandwagon. I would like to thank him for taking the time to highlight issues and to praise our work at the Ehrenberg-Bass Institute.

Associate Professor Rachel Kennedy knows a thing or two about the work of the Ehrenburg-Bass Institute
As one of those women John says control 85% of purchases (and I do control most purchases for my household), let me say I’m all for ads that give me an emotional response.
However, as with John’s article, some of our messages can be misinterpreted. So, I want to clarify our position on some issues raised:
You won’t find us talking about mass awareness.
What we do advocate is mental availability, building and refreshing mental structures – this is different to awareness, and vitally important.
We do advocate targeting. Smart targeting.
We don’t simply promote targeting everyone with every communication – there is lots of number crunching and planning to be done to get scale reach.
Advertising creativity matters enormously.
Good copy drives sales. It is hard to produce such winning copy, but creativity should be a top priority for marketers.
All brand ads also need to be easily recognisable by distracted audiences – there are many other ways to do this creatively than just making the logo bigger. However, we do see money wasted on poorly branded ads with small logos.
Emotional response to copy matters – for women and for men.
It increases the chance that the advertising will work by building or refreshing relevant memory structures.
This helps brands to be remembered and considered for purchase. It is vital to get the short-term response and build memories for the long-term.
You must reach beyond current buyers if you want to grow your brand.
We encourage marketers to know the numbers that are relevant to their category (e.g. who buys the category) and to be as inclusive of category buyers as they can be (i.e. within the available budget).
Missing out men will rarely to be a growth strategy – even fathers and boyfriends have to buy tampons sometimes (so brands like Libra and Tampax should try and be easy to buy, even for such disinterested shoppers).

Everyone shops in the tampon aisle
So, should we target copy to specific audiences (e.g. women)?
Marketers need to invest in great copy that drives as many sales as possible (over the long term). Rather than imagining if tweaked copy can be more effective, we promote robust measurement of the response that different copies receive (e.g. via split cable experiments, single source data), which allows marketers to be evidenced-based in these decisions.
Ideally what we want to be producing are campaigns that are broadly appealing (e.g. nudge the whole market). This saves us producing lots of different copy allowing more of our budget to be put into people seeing our copy.
That said, there are times when different copies are needed for different audiences (e.g. if a large part of the market speaks Chinese then reaching those people with Chinese copy is likely to be sensible). We are yet to see evidence that gender targeting leads to a better total uplift. If you have any, we would love to see it.
On a final note, I agree with John that implementation of the science is a challenge distinct from understanding the discoveries.
We are trying to document the impact that marketers have (cases where implementation of the science has worked well, as well as anywhere it has failed). We would be pleased to hear from anyone who is happy to share the impact they have got from applying the knowledge we have shared.

Thank you for clarifying, Rachel.
A very elegant pin in my balloon.

Just one question:
Often I feel EBI contradicts itself. For example, we hear Bruce McColl saying his target is all 7bn people on this planet.
But not everyone on this planet will be a category buyer for sweets and chocolate. How does that work with your law to ‘target category buyers’?
I am equally surprised about your tampon example above. Men are certainly not the category buyer either?
Sometimes I think you guys need to be more coherent and careful with your messages.

I do have one question.
While you haven’t seen evidence that gender targeting leads to a better total uplift, have you seen evidence that gender targeting hinders uplift?
Have there been any studies at all into the effectiveness, or not, of gender targeting?
(Sorry, two questions.)
I appreciate your time Rachel. Thanks for keeping the conversation going.

Hi Rachel, it’s an interesting comment you make about single source data. I get it in certain international markets, but is that a suggestion in Australia?
My understanding is single source data here is either;
a) Fused data. The robustness of this is questionable at best, and I was involved in constructing one of the largest- on what basis is a respondent that “saw” the ad the same as the respondent from another panel that purchased the product. The error margins are massive.
b) Based off STV data or MCN- which means we’re looking at the 20% rather than the 80%.
Or am I missing another source?
I’m a huge fan of your work, and bringing science and rigor to marketing decisions, but just concerned that if that rigor is based on junk data, doesn’t garbage in = garbage out?

We are often trying to summarise decades of research and many studies in simple to understand ways. We do appreciate there is enormous complexity to much of what we research and we invest enormously in documenting and describing what we find. We would love it if more marketers read more of the detail that we write rather than reading too much into the likes of PR responses that have to be written quickly and can never cover the depth of knowledge we are trying to share.

John I have not. I’ve also not specifically looked for them. Controlled in-market experiments could be fun … but based on what we have seen I’d suggest there are other priorities for brands that want to grow

Was not specifically a suggestion for Australia (what we write tends to get shared around the world). Agree with you that fused data is not the same as single source. In some categories there is some single source but it is not widely available here. Totally agree with you that we need quality data to under pin evidence-based decisions.

I am a man, and I have bought tampons for my wife, just as Rachel suggests some men do.

Hi Rachel,
I find this article fascinating. Especially what you say about the need for strong advertising copy (that has the ability to nudge the whole audience) that can trigger an emotional response.
We’re in the business of dynamic audio which strikes a chord on both of those notes. Would it be worth an intro?
