A Hypothesis Of The Co-Evolution Of Cooperation And Inequity, Sarah F. Brosnan
A Hypothesis Of The Co-Evolution Of Cooperation And Inequity, Sarah F. Brosnan
Psychology Faculty Publications
Recent evidence demonstrates that humans are not the only species to respond negatively to inequitable outcomes which are to their disadvantage. Several species respond negatively if they subsequently receive a less good reward than a social partner for completing the same task. While these studies suggest that the negative response to inequity is not a uniquely human behavior, they do not provide a functional explanation for the emergence of these responses due to similar characteristics among these species. However, emerging data support the hypothesis that an aversion to inequity is a mechanism to promote successful long-term cooperative relationships amongst non-kin. …
Property In Non-Human Primates, Sarah F. Brosnan
Property In Non-Human Primates, Sarah F. Brosnan
Psychology Faculty Publications
Property is rare in most nonhuman primates, most likely because their lifestyles are not conducive to it. Nonetheless, just because these species do not frequently maintain property does not mean that they lack the propensity to do so. Primates show respect for possession, as well as behaviors related to property, such as irrational decision making regarding property (e.g. the endowment effect) and barter. The limiting factor in species other than humans is likely the lack of social and institutional controls for maintaining property. By comparing primates and humans, we gain a better understanding of how human property concepts have evolved.
