An early lead: New study reveals consumer inclination to bias information in favor of market leaderA groundbreaking new study from the forthcoming issue of the Journal of Consumer Research explores a previously unexposed market phenomenon: the powerful influence of "leader-driven primacy" on consumer choice. Consumers, argue the researchers from Duke University, are very likely to give subsequent support to the brand that first appears to show superiority in its category. We might even be influenced to choose an inferior product if the earliest information we get about it is positive.
"Our research shows how information order can be used to create a tentative preference for one option over another," explain the researchers. "Once a leader emerges, consumers build support for it by biasing their interpretation of new information to favor it. The consequence of this process is that it is possible to dictate which brand consumers ultimately select, merely by changing the order of the information."
The researchers examined leader-driven primacy in three studies, using backpacks, winter coats, and restaurants as test subjects. In one study, two options were intentionally made to be equivalent overall. In another, one choice was markedly superior. In both studies, the researchers were able to influence which brand was favored, noting "this is the first paper to show that information order can be used to influence choice in such a way."
In the third study, the researchers explored a method to reduce the effect of leader-driven primacy: they had subjects focus more on the whole brand than on the individual features of each brand. Sure enough, these particular subjects were more objective and less influenced by early positive information about a brand.
