What is Injunctive norms?
Injunctive norms are perceptions of what most people approve or disapprove of in a given situation. They reflect what people think they should do, distinct from descriptive norms (what people actually do).
How it works
Cialdini’s focus theory shows that injunctive and descriptive norms can align (most people recycle AND most people approve of recycling) or conflict (most students drink excessively BUT most students disapprove of excessive drinking). When they conflict, the norm that is made salient at the moment of decision has the greater influence. Injunctive norms operate through social reward and punishment: people follow them to gain approval and avoid censure. They are more stable than descriptive norms because they represent values rather than behaviors.
Applied example
A littering experiment showed that people who saw a clean park (descriptive norm: nobody litters here) were less likely to litter, but only when an injunctive norm was also activated (a person visibly picking up trash, signaling disapproval of littering). The injunctive norm amplified the descriptive norm’s effect.
Why it matters
Injunctive norms provide the moral backbone of social behavior, motivating compliance through the desire for social approval even when descriptive norms are absent or ambiguous.
