I have two areas of research interest. I am primarily interested in the nature of cooperation within interdependent groups, especially groups faced with a social dilemma. In particular, I look at the role of individual differences in cooperation, and the impact of cognitive processes on cooperation. We have also begun to study how people react to group members who exhibit counternormative behavior within a social dilemma, specifically those who free ride, and those who have a high level of benevolence. The latter are people who do much to help the group and ask for little in return.
Surprisingly, we have found that benevolent people are not very popular in the long run. This seems to be because some people see benevolent individuals as an undesirable standard of comparison; some fear that the person will cause the group norm to shift from equitable behavior to benevolence; and a few see suspicious ulterior motives in benevolent behavior. We are currently trying to determine what individual and situational factors lead people to be more or less tolerant of benevolent individuals.
Jeff Joireman, Paul Van Lange and I have recently published a comprehensive model of the influences on cooperative choice in a social dilemma. We suggest that the model can be integrated with factors that produce hostility between groups to produce a complete picture of under what conditions a person will support a publicly beneficial good; when they will support its existence but not contribute toward it; and when they will actively work to suppress it.
I also study processes within decision-making groups. Here, I emphasize how the initial, pre-discussion distribution of individual preferences affects the ensuing process of reaching consensus. We have shown, for example, that group members who are initially unanimous as to what option should be adopted still feel the need to discuss the issue; it is unclear why. We are also looking into the the dynamics of small majorities, in particular whether their smallness undercuts the influential power usually ascribed to majorities.
