Researchers studying human and non-human primates have begun exploring deviations from the canonical model of expected utility. Additionally, researchers have examined the role of inequality in decision-making across the taxa. However, these two research programs are rarely combined. In this paper we offer an examination of the role and impact of risk and inequity on decision-making in both human and non-human primates. We also offer insights into what drives these observed differences, considering a range of explanations from biological to methodological.
