Framing Descriptive Norms as Self-Benefit Versus Environmental Benefit: Self-Construal's Moderating Impact in Promoting Smart Energy Devices

Recently, awareness has been raised concerning the importance of sustainable energy use. Nevertheless, many obstacles must be overcome to change individuals' energy consumption habits. This study examines how a message should be framed to convince individuals to purchase a smart energy device that provides feedback on household energy use. As such, this device can assist households in adjusting their energy-wasting habits. Through two experimental studies, this paper examines how a descriptive normative message, indicating that the majority of US households have already purchased a smart energy device, can increase individuals' intention to purchase the device. Both studies consider the moderating influence of the self-construal, which refers to individuals' consideration of themselves as either part of a group (interdependent self-construal) or independent from others (independent self-construal). The first study (n = 231) reveals that a descriptive norm (versus no norm) leads to a higher purchase intention through an enhanced normative influence regardless of participants' self-construal. The second study (n = 128) adds to the finding that combining a descriptive norm with a self-benefit (versus environmental) frame more strongly impacts the purchase intent of individuals with a dominant independence. No significant differences are identified between the two benefit frames' effectiveness among individuals with a dominant interdependence.
