A while ago, we recounted the story of how a simple divider in a shopping cart can radically change shopping behavior. In fact, the little sign that said, "place produce here, all other products there" doubled fresh produce purchases during the experiment.
Additional secondary research by Collin Payne and Mihai Niculescu found that this was massively more effective than other produce marketing methods (shelf labeling, advertising, coupons, etc.), which often only increased sales a couple percentage points.
But we began to wonder if such a persuasive marketing method would ever survive the standby of shopper research: the direct response survey of purchase intent. So we fielded the question to a panel of 4,593 US shoppers.
We found that a cart divider ranked last in what people claim would influence them to buy more produce.
When asked directly if a cart divider would influence their produce purchases, an overwhelming majority said it would have no effect.
