What term describes the principle where treating others well encourages them to treat you well in return?

The term that describes the principle where treating others well encourages them to treat you well in return is reciprocity. This concept is rooted in social psychology and emphasizes the mutual exchange of positive actions between individuals. When someone shows kindness, support, or generosity, it establishes a norm of reciprocity that motivates the recipient to respond in a similar manner. This can create a cycle of goodwill and cooperation, fostering stronger relationships both personally and professionally.

Reciprocity is particularly important in various contexts, such as business negotiations, social interactions, and community building, as it can lead to trust and collaboration. The other terms, while related to social interactions and dynamics, do not capture this specific principle of mutual benefit arising from kind actions. Affiliation refers to the need for social connections, collaboration involves working together towards a common goal, and mutualism typically refers to a biological term indicating a relationship where both parties benefit but does not specifically pertain to human social interactions in the same way as reciprocity.
