Understanding the “Fundamental Sociality of the Human Mind”

The human species is equipped with a hyper-sensitive sociality, meaning that people are never indifferent to the welfare and states of other people around them, in both positive (e.g., empathy, altruism) and negative (e.g., jealousy, prejudice, discrimination) ways. The ultimate goal of our laboratory is to understand the evolutionary and socio-ecological bases of such hyper-sociality and to clarify how various uniquely human faculties are implemented in our minds as adaptive behavioral-cognitive systems. Through collaborations with researchers in adjacent disciplines including neuroscience, economics, evolutionary biology, informatics, jurisprudence and ethics, we hope to synthesize the normative wisdom accumulated in the humanities and social sciences addressing “how we should behave and construct our society” to the empirical knowledge obtained from behavioral, cognitive and neurosciences.
