Journal ArticleDOI
Cues of being watched enhance cooperation in a real-world setting
TL;DR: This paper examined the effect of an image of a pair of eyes on contributions to an honesty box used to collect money for drinks in a university coffee room and found that people paid nearly three times more for their drinks when eyes were displayed rather than a control image.
Journal ArticleDOI
Why individual vigilance declines as group size increases
TL;DR: In this paper, the authors pointed out that the functional explanation of the group size eVect remains unclear, and suggested that the individual risk hypothesis, with group vigilance as one element, provides a more general framework for understanding variation in vigilance behaviour with group size and with other factors.
Journal ArticleDOI
Competitive altruism: from reciprocity to the handicap principle
TL;DR: In this article, the authors discuss how introducing differences in individual generosity together with partner choice into models of reciprocity can lead to an escalation in altruistic behavior, referred to as competitive altruism.

TL;DR: It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
Journal ArticleDOI
Development of cooperative relationships through increasing investment
TL;DR: It is shown that cooperation can thrive despite variable investment through the new strategy of ‘raise-the-stakes’, which offers a small amount on first meeting and then, if matched, raises its investment, something that no strategy in the discrete model can do.
