RIKEN Center for Brain Science Social Value Decision Making Collaboration Unit
Unit Leader: Rei Akaishi (Ph.D.)
Research Summary
Societies around the world are now changing rapidly and in an accelerating pace. Research disciplines for studies of human being have not caught up with the rapid changes of the societies. To address these issues, our laboratory combines the research fields of decision science such as neuroeconomics, behavioral economics, psychology. In addition to these research fields of individual decision making, we will extend and connect principles of decision making to decision making at group and society levels with the aid of analysis techniques of big data, which are developed in new fields of collective behavior. Our research will bring about positive impacts to people in society by enhancing scientific understanding of humans and by creating sustainable designs of social systems. Through this exciting research endeavor, we create positive values for people in our global society.
