Insights into the evolution of the sense of fairness

Researchers have found that long-tailed macaques reject inferior rewards more frequently when provided by a human than an automatic feeder, indicating social disappointment. This behavioral pattern is consistent with frustration towards the experimenter's decision, rather than a comparison of rewards with conspecifics.
