After all, from a natural selection point of view, the only relevant output is the successful identification of cheaters and cooperators with as low a cost and error rate as possible, since such ability is essential for both direct reciprocal cooperation [43], and reciprocity based on reputation [15].
However, in contrast to the demanders' interest, the sharing benefit is defined according to the reciprocal cooperation, more generally, the combination of evolution, altruism, and reciprocity.
That support should earn reciprocal cooperation and respect for American policy from its ally, not to mention non-interference in its domestic politics.
This results in a lack of trust between knowledge production and knowledge application organisations for developing effective and reciprocal cooperation relationships (Wang 2011).
In summary, "benefit to the world" is a general conception of welfare comprising social harmony and public security; economic prosperity and a thriving population and family; reciprocal cooperation among neighbors and charity for the needy; and good social relations, manifested in the exercise of virtues corresponding to the fundamental social roles.
Frequent interspecific interaction can lead to negative feedback (eg, competition and predation) and reciprocal cooperation (mutualism), with fitness reflecting the trade-off between balancing individual sacrifice, if any, and traits that benefit the group, for example, stabilization of population, food web, or ecosystem structure.
A simple reciprocal experimental paradigm which prevented direct physical interaction between participants failed to elicit chimpanzees' other-regarding preferences, reciprocal cooperation [22] and spontaneous barter [44].
The act of cross-feeding whereby unrelated species exchange nutrients is a common feature of microbial interactions and could be considered a form of reciprocal altruism or reciprocal cooperation.
The success of reciprocating strategies in theoretical models of iPD games has been corroborated experimentally by numerous reports on the emergence of reciprocal cooperation between human subjects while playing iPD games [22] [24].
However, even seemingly highly mutualistic interactions (e.g. between plants, mycorrhizal fungi and/or rhizobia) are inherently unstable, because reciprocal cooperation is based on mutual exploitation and thus costs and benefits are rarely symmetric to the partners [1] [7].
