Green and Mean: Eco-shopping Has a Side-Effect

So you decided to buy a nontoxic cleaning product? Good for you. Just don’t get too self-congratulatory. Purchasing a green product could make you more likely to behave more selfishly down the road, a new study reveals.

Researchers at the University of Toronto asked college students to shop for products online from either an eco-friendly or a conventional store. Then, in a classic experiment known as the dictator game, subjects were asked to divide a small sum of money between themselves and a stranger. Those who shopped at the green store shared, on average, less of their money.

The investigators believe that a “licensing effect” might be at work. “When we engage in a good deed, that gives us a kind of satisfaction,” says Nina Mazar, professor of market ing and a co-author of the paper. With that self-satisfied feeling can come tacit permission to behave more sel fishly next time we have the oppor tunity, Mazar says. Previous research has documented this licensing effect in other contexts; a study published last year revealed that asking people to ruminate on their humanitarian qualities actually reduced their char itable giving.

Next, Mazar is particularly in terested in exploring the policy implications of this licensing effect; for instance, one study suggested that people who make their homes more energy-effi cient start cranking up their heat. She hopes to determine whether simply making people aware of these kinds of tendencies could help combat them.
