Research Project "Evolutionary Insights into Social Intelligence. A comparison between humans, bonobos, and chimpanzees”. Why do humans cooperate in large numbers to advance projects for the common good? Contrary to the conventional wisdom in biology and economics, this generous and civic-minded behavior is widespread and cannot be explained simply by self-interest. People cooperate not to benefit themselves or their close genealogical kin, but do so out of an intrinsic empathic motivation. However, humans are also familiar with betrayal, exploitation and subordination and as a consequence at times refrain from cooperation. We like to see ourselves as intelligent ‘SuperCooperators’, unique among animals. But are we? While most research emphasizes the superiority of humans over other species, increasing evidence suggests that if it comes to social intelligence, some other species have skills that are superior to those of humans. Within this research project, cooperation is treated as the ultimate socially intelligent behavior as it increases the common good, which in the end benefits all individuals within the group. Further, emotional expressions and their recognition, possibly informed by emotional mimicry are considered important drivers of cooperative behavior. In sum, the project challenges the view that humans are the most socially intelligent species. The project will run in parallel with ongoing projects in the CoPAN lab, directed by Dr. Mariska Kret (www.mariskakret.com). The research group participates in the Leiden Institute for Brain and Cognition (LIBC), an interfaculty center for interdisciplinary research on brain and cognition (www.libc-leiden.nl).
