Humans are an exceptionally social species and, thus, most human thought revolves around other people, oneself, and the self-other relationship. Psychologists have recently realized that humans primarily think about self and others alongside two basic dimensions: “Agency” (also called “intellectual goodness,” “power,” or “dominance”) and “communion” (also called “moral goodness,” “benevolence,” or “nurturance”). This realization has been a major breakthrough. But it also raised a cardinal question: Why did evolution forge the human mind this way?
My ERC project seeks to answer this question, and the answer comes in the form of a theory with the following key idea: Humans have been having remarkable evolutionary success over the last 300,000 years and evolutionary anthropologists largely credit this success to one specific ability: Humans’ exceptional social learning ability. More precisely, humans are so good at learning from each other that the knowledge and skills they gain from others accumulate over generations. This accumulation creates complex, open-ended culture in which humans have thrived formidably, have spread across all terrestrial areas of planet earth and have exploded in number. However, not all social learning is beneficial. In fact, social learning is only beneficial if one learns from the “right” individuals. And this is where agency and communion come in: According to the novel theory, the right individuals to learn from are those high in agency and high in communion. In short, then, evolution has forged a human mind that revolves around agency and communion, because such a mind enables humans to learn socially in the most effective manner and, thereby, create complex, open-ended culture and thrive within it.
