Significance
Many household decisions, such as where to set the thermostat or whether to acquire a new vehicle, are not made independently by individuals, but rather by multiple people through the process of conversation. However, most studies investigating sustainable household behavior rely on paradigms that collect data from a single individual or examine household-level outcomes (e.g., utility bills). Understanding how people interact around joint environmentally-relevant decisions is critical for more accurately modeling the behavioral contributions to sustainability.
