New Study Shows Reputation Trumps Money  Whether it’s an attempt to increase recycling rates, reduce energy consumption or cut carbon emissions, conventional wisdom says the best way to get people to do the right thing is to make it worth their while with financial incentives.

But a new study shows that there may be an easier — and cheaper — way: by boosting people’s reputations through the use of peer pressure.

Using a California blackout prevention program as an experimental test bed, a team of researchers found that while financial incentives increased participation slightly, making participation in the program observable to neighbors through the use of signup sheets posted in apartment buildings produced a threefold increase in participation.

“We wanted to see how observability compares to a cash incentive for getting people to act to benefit the common good. The answer is that observability is really dramatically better,” said David Rand, formerly a post-doctoral fellow at Harvard University’s Program for Evolutionary Dynamics (PED), who is now a professor at Yale University.

Using a cash incentive of $25, the utility company saw participation increase from about three percent to four percent. When researchers made people’s participation observable, participation jumped from three to nine percent. To get the same result using a cash incentive, the company may have had to offer every person as much as $175, said Erez Yoeli, a researcher at the Federal Trade Commission.

Observability proved to be the key factor in the results because it puts people’s reputation at stake, encouraging those who might not otherwise sign up to do so, according to the researchers.

“When people know it’s a cooperative effort, they feel peer pressure to take part,” Rand explained. “They think, ‘If I don’t do this, I’m going to look like a jerk.’ But if it’s not observable, then there’s no problem with not participating.”

“In fact, we think this is one reason why the Prius, for instance, is such a different-looking car,” added Moshe Hoffman, a visiting researcher at PED. “The designers at Toyota seem to have intuitively had this idea, designing a car that didn’t look like any other car so your neighbors can tell you’re driving a hybrid.”

“You can also see this phenomenon when you go to vote, and you get an ‘I voted’ sticker,” he continued. “Or when you go to give blood and you get a pin you can put on your backpack.”

To demonstrate the effect of observability in a real world setting, the researchers turned to a large-scale California blackout prevention program. Residents were asked for permission to install a monitoring device on their air-conditioning systems. If power demand spiked, the device would automatically adjust the air-conditioning temperature to reduce electricity demand and not overload the power grid.

Researchers randomly offered people one of two ways to sign up for the program.

In the first, people received a mailer that described the program, and were encouraged to sign up in their apartment building using a unique identification number. In the second, people received a similar mailer and identification number, but also had to write their name and apartment number when they signed up.

“The idea was that in one case, it’s anonymous, and in the other, it’s observable — everyone can see who has and hasn’t signed up,” Rand said. “When participation is observable, people worry about their reputation, and wanting to seem cooperative drives them to sign up.”

To support the explanation for the increased sign ups when participation was observable, the researchers point to three pieces of evidence: First, tests showed that the effect was greater in large apartment buildings — where more people were likely to see the sign-up sheets — than in row houses, which have less common space.

Second, tests showed that the effect was more pronounced among people who own their apartments than among renters.

“People who own their apartments are real, permanent members of their community,” Rand said. “They are more likely to care about what other people in the community think of them. If you are a renter, by comparison, you may not even know any of your neighbors.”

Finally, tests showed observability only increased participation when the program was portrayed as a community-wide benefit, the researchers noted.

“We showed that signing up only matters when others can see it, and particularly when people you care about can see it. But we also wanted to show that it matters whether people think you are being cooperative or not,” Rand said. “If you think about the way reputation works, you can get a bad reputation for being selfish, but things that don’t involve a cooperative element — like signing up for a promotion offered by your utility that has no effect on others — aren’t going to affect your reputation.”

Ultimately, the study suggests that similar strategies could be relatively cheaply and easily employed to boost participation in a host of programs to improve community-wide efforts, the researchers suggest.

“This finding is very policy-relevant, because we’re talking about changing real-world behaviors that are economically significant,” Rand said. “The moral here is that these type of reputation concerns deserve a prominent place in the toolkit used by policy makers to encourage people to do things that benefit the public good. We think that observability and reputation concerns are powerful tools that are being under-utilized.”

Their study was published in the Proceedings of the National Academy of Sciences.
