The Principle of Social Proof: People Follow the Lead of Similar Others

The Application: Use Peer Power Whenever It's Available.

Social creatures that they are, human beings rely heavily on the people around them for cues on how to think, feel, and act. We know this intuitively, but intuition has also been confirmed by experiments, such as the one first described in 1982 in the Journal of Applied Psychology. A group of researchers went door-to-door in Columbia, South Carolina, soliciting donations for a charity campaign and displaying a list of neighbourhood residents who had already donated to the cause. The researchers found that the longer the donor list was, the more likely those solicited would be to donate as well.

To the people being solicited, the friends' and neighbors' names on the list were a form of social evidence about how they should respond. But the evidence would not have been nearly as compelling had the names been those of random strangers. In an experiment from the 1960s, first described in the Journal of Personality and Social Psychology, residents of New York City were asked to return a lost wallet to its owner. They were highly likely to attempt to return the wallet when they learned that another New Yorker had previously attempted to do so. But learning that someone from a foreign country had tried to return the wallet didn't sway their decision one way or the other.

The lesson for executives from these two experiments is that persuasion can be extremely effective when it comes from peers. The science supports what most sales professionals already know: Testimonials from satisfied customers work best when the satisfied customer and the prospective customer share similar circumstances. That lesson can help a manager faced with the task of selling a new corporate initiative. Imagine that you're trying to streamline your department's work processes. A group of veteran employees is resisting. Rather than try to convince the employees of the move's merits yourself, ask an old-timer who supports the initiative to speak up for it at a team meeting. The compatriot's testimony stands a much better chance of convincing the group than yet another speech from the boss. Stated simply, influence is often best exerted horizontally rather than vertically.
