"Quero o champô que tem mais garrafas na prateleira"

Rory Sutherland, vice chairman da Ogilvy, sobre como os consumidores realmente fazem as suas escolhas:

What we realise is that as you get closer to the point of decision, there are factors at work which never really appear in conventional market research. They are contextual factors, social factors. No-one in any research group would ever say, “If there are four brands of shampoo, I’ll buy the one that has most bottles on the shelf”, or “I’ll choose the one that’s on the third shelf up because it’s the one that doesn’t require much reaching down” or “I’ll look at the prices of three products and choose the one in the middle.”

In reality, we use heuristics and shortcuts and cognitively miserliness like this all the time. The mistake that quite a lot of advertising methodologies make is assuming that brand preference translates perfectly into purchase behaviour. It’s also making the assumption, of course, that preference is formed in advance of behaviour. Quite a lot of evidence from both behavioural sciences and from neuroscience suggests that we act first and form our opinions in light of our actions.

If there happens to be a Starbucks on the way to work you will end up going to that more than Costa Coffee, and as a result of that action and in order to make sense of that action, you’ll decide to like Starbucks. And when a market researcher comes up and asks what is your preferred coffee chain, you’ll say Starbucks. But in effect, your preference is a product of your behaviour and not the origin of it. I often say that if you hear a man complain that his wife doesn’t understand him, it doesn’t mean he’s going to have an affair – it means he’s already had one.
