Injunctive norms refer to the perceptions of what behaviors are approved or disapproved by a group or society. These norms guide individuals on how they should act in specific situations based on social expectations. For example, if a community values environmental conservation, individuals may feel pressured to recycle and reduce waste to align with these expectations. These norms can influence behavior significantly, as people often want to fit in and be accepted by their peers. Injunctive norms can be communicated through various channels, such as media, laws, or social cues, shaping individual choices and promoting certain actions over others.
