Now that OPOWER is using social science to help us encourage our Facebook friends to save energy, I’ve become curious about the role of social circles in environmentalism. Do environmental values diffuse socially into the larger community? And, if they do, how can one accelerate that process?
Eco-friendly choices aren’t the only kind of behavior that may be contagious. Weight loss studies imply that people both adjust their size to match their friends and cluster socially based on their weight. The book The Social Animal says people not only mirror the facial expressions of their families, but subtly seek out partners and friends who mirror their own appearances and values. This mirroring and filtering process is both subtle and continuous.
Advertising encourages us to use product choices to express ourselves – thereby showing our values, interests and character to potential coworkers, friends and partners. Even being “real” – for example, going without makeup – can be a statement. So can environmental decisions.
Including social circles in one’s perspective can lead to intriguing questions about environmentalism. How do environmentalists find each other? If environmentalists cluster too closely, will our innovations diffuse into the rest of society? On the other hand, if we spread out into a dispersed community, will we still be able to change the culture around us? If we want our social norms to catch on, what should we do? Should we try to reach a critical mass? Should we look for tipping points?
