Definition
Reciprocity is the social rule that we feel obligated to repay, in kind, what another person has provided to us.
Origin
Alvin Gouldner (1960) argued the norm of reciprocity is near-universal across human societies and foundational to social stability: receiving creates an obligation to give back. Robert Cialdini later placed reciprocation first among his principles of influence, documenting how even small or unrequested gifts generate disproportionate return obligations.
Mechanism
A received benefit creates a felt debt that persists until discharged, and the discomfort of standing in debt motivates repayment — often beyond the value first received.
Gift creates obligation — repay, or pause on engineered favours. Pair Automatic influence levers · Influence.
The rule operates somewhat automatically and can be triggered by uninvited gifts, concessions (reciprocal concessions underlie the “door-in-the-face” tactic), and favours. Its power and its automaticity are precisely what make it a lever for influence, and a vulnerability when exploited.
Applications
- Explaining why free samples, favours, and concessions raise compliance.
- Building cooperation and trust through genuine first-giving.
- Recognising manipulated reciprocity (an engineered “gift”) and declining the implied debt.
