vědci (sice američtí, ale adresně z Center for Cognitive Neuroscience, Duke University Medical Center, Durham, North Carolina) zjistili, že makakové jsou ochotní platit za fotky makaků s vysokým sociálním statusem (a nebo makačí porno), ale vyžadují, aby jim vědci platili za to, že se budou koukat na fotky makaků s nízkým sociálním statusem.

Individuals value information that improves decision making. When social interactions complicate the decision process, acquiring information about others should be particularly valuable [1]. In primate societies, kinship, dominance, and reproductive status regulate social interactions [2, 3] and should therefore systematically influence the value of social information, but this has never been demonstrated. Here, we show that monkeys differentially value the opportunity to acquire visual information about particular classes of social images. Male rhesus macaques sacrificed fluid for the opportunity to view female perinea and the faces of high-status monkeys but required fluid overpayment to view the faces of low-status monkeys. Social value was highly consistent across subjects, independent of particular images displayed, and only partially predictive of how long subjects chose to view each image. These data demonstrate that visual orienting decisions reflect the specific social content of visual information and provide the first experimental evidence that monkeys spontaneously discriminate images of others based on social status.
