Gary Bornstein (1953-2012)

Gary Bornstein was a Professor of Psychology. He was also a member of the Center for the Study of Rationality and Interactive Decision Theory and the Director of RatioLab (the Laboratory for Interactive Decision Research). His main areas of research were intergroup conflict and group decision-making in strategic settings.

Research Interests

Intergroup Conflict:

    Intergroup conflicts entail conflicts of interests within the competing groups as well. Gary studied a class of games which incorporate the intragroup and intergroup levels of conflict. These games provide a theoretical framework for analyzing the prototypical problems of cooperation and competition that arise within and between groups. They also constitute an effective experimental paradigm for studying individual and group behavior in the laboratory.

Group decision-making:

    Whereas important strategic decisions are often made by groups (e.g., boards of directors, committees, governments), the experimental study of strategic decision-making has typically used individuals as the decision-making agents. The following experiments compare individual and group decisions in strategic (interdependent) settings.
