RECIPROCITY

In social psychology, reciprocity is a social norm of responding to a positive action with another positive action, rewarding kind actions. As a social construct, reciprocity means that in response to friendly actions, people are frequently much nicer and much more cooperative than predicted by the self-interest model; conversely, in response to hostile actions they are frequently much more nasty and even brutal.[1]

Reciprocity makes it possible to build continuing relationships and exchanges. Fukiyama [2] states that “If the institutions of democracy and capitalism are to work properly, they must coexist within certain premodern cultural habits that ensure their proper functioning” (p. 11). He goes on to say “Law, contract, and economic rationality and prosperity…. must as well be leavened with reciprocity, moral obligation, duty toward community, and trust…. The latter are not anachronisms in a modern society but rather the sine qua non of the latter’s success” (p. 11) According to the sociologist Alvin Gouldner (1960), this norm is nearly universal, and only a few members of society—the very young, the sick, or the old—are exempt from it.[3]

Reciprocal actions differ from altruistic actions in that reciprocal actions only follow from others' initial actions, while altruism is the unconditional act of social gift-giving without any hope or expectation of future positive responses.[4][5] Some distinguish between ideal altruism (giving with no expectation of future reward) and reciprocal altruism (giving with limited expectation or the potential for expectation of future reward).
