Research shows that commitment-based interventions are among the most effective strategies to encourage pro-environmental behaviors, but methods to elicit commitments from a large number of individuals are often costly and unrealistic. Predictions requests—a commitment-type strategy—are an effective mass-communication strategy and have the potential to influence pro-environmental behavior among large audiences. This research is the first to demonstrate that prediction requests in a consumer behavior context influence preference for environmentally friendly products. In addition, this research examines the role of individual and (...) contextual factors in influencing the efficacy of prediction requests. Study 1 shows that exposure to an advertisement with a prediction request leads to increased preferences for environmentally sustainable household cleaning products, compared to a control advertisement, and that this effect is greater when the prediction request is paired with an audience cue . Study 2 indicates that the effect of prediction requests on preference for sustainable products is greater for individuals with interdependent self-construal. Substantive implications and directions for future research are discussed. (shrink)

From an evolutionary point of view, the function of moral behaviour may be to secure a good reputation as a co-operator. The best way to do so may be to obey genuine moral motivations. Still, one's moral reputation maybe something too important to be entrusted just to one's moral sense. A robust concern for one's reputation is likely to have evolved too. Here we explore some of the complex relationships between morality and reputation both from an evolutionary and a cognitive (...) point of view. (shrink)
