Optional conservation recommendations are more effective than mandates
Energy and water conservation recommendations ask individuals to conserve their use of these utilities, such as turning off the lights when leaving a room. Research shows that people need a reasonable number of options to give them agency and limit indecision. Listing five behaviors as examples rather than making them seem mandatory might improve the outcome. The elaboration likelihood model (ELM) says a person's elaboration of a message, or how much conscious effort they put into understanding the message, influences how deeply they can be persuaded.
