Reciprocity
People feel compelled to return favors or kindnesses, increasing compliance and positive attitudes.
Why it works
Rooted in evolutionary cooperation theory and social exchange theory (Gouldner, 1960), reciprocity creates psychological debt that motivates people to restore balance in relationships. This universal social norm helped humans survive through cooperation and is deeply ingrained in decision-making processes (Cialdini, 2007).
