3. The Blind Leading the Blind

The difficulty with interpreting the Pepsi Challenge findings begins with the fact that they were based on what the industry calls a sip test or a CLT (central location test). Tasters don’t drink the entire can. They take a sip from a cup of each of the brands being tested and then make their choice. Now suppose I were to ask you to test a soft drink a little differently. What if you were to take a case of the drink home and tell me what you think after a few weeks? Would that change your opinion? It turns out it would. Carol Dollard, who worked for Pepsi for many years in new-product development, says, “I’ve seen many times when the CLT will give you one result and the home-use test will give you the exact opposite. For example, in a CLT, consumers might taste three or four different products in a row, taking a sip or a couple sips of each. A sip is very different from sitting and drinking a whole beverage on your own. Sometimes a sip tastes good and a whole bottle doesn’t. That’s why home-use tests give you the best information. The user isn’t in an artificial setting. They are at home, sitting in front of the TV, and the way they feel in that situation is the most reflective of how they will behave when the product hits the market.”

Dollard says, for instance, that one of the biases in a sip test is toward sweetness: “If you only test in a sip test, consumers will like the sweeter product. But when they have to drink a whole bottle or can, that sweetness can get really overpowering or cloying.” Pepsi is sweeter than Coke, so right away it had a big advantage in a sip test. Pepsi is also characterized by a citrusy flavor burst, unlike the more raisiny-vanilla taste of Coke. But that burst tends to dissipate over the course of an entire can, and that is another reason Coke suffered by comparison. Pepsi, in short, is a drink built to shine in a sip test. Does this mean that the Pepsi Challenge was a fraud? Not at all. It just means that we have two different reactions to colas. We have one reaction after taking a sip, and we have another reaction after drinking a whole can. In order to make sense of people’s cola judgments, we need to first decide which of those two reactions most interests us.

Then there’s the issue of what is called sensation transference. This is a concept coined by one of the great figures in twentieth-century marketing, a man named Louis Cheskin, who was born in Ukraine at the turn of the century and immigrated to the United States as a child. Cheskin was convinced that when people give an assessment of something they might buy in a supermarket or a department store, without realizing it, they transfer sensations or impressions that they have about the packaging of the product to the product itself.
