We investigate the antecedents of conflict on collocated as compared with geographically distributed teams. In our field study of 16 collocated and 20 geographically distributed research and development teams, we found little evidence that distributed teams have more conflict. However, we did find that distributed teams experienced more coordination problems and less healthy conflict handling n...

The literature on social polarization predicts that redistributive conflicts will be most intense in societies with two equally large groups. However, the effect of relative group size on the risk of onset of violent conflict remains unexplored. In this paper we study a game between a rentextracting government and an excluded social group which can explain the determinants of conflict onset and...

This paper examines the impact of ethnic divisions on conflict. The empirical specification is informed by a theoretical model of conflict (Esteban and Ray, 2011) in which equilibrium conflict intensity is related to just three distributional indices of diversity: ethnic polarization, ethnic fractionalization, and a Greenberg-Gini index of “difference” constructed across ethnic groups. Our empi...

In social species, conflict with outsiders is predicted to affect within-group interactions and thus influence group dynamics and the evolution and maintenance of sociality. Although empirical evidence exists for a relationship between out-group conflict and intragroup behavior in humans, experimental tests in other animals are rare. In a model fish system, we show that simulated out-group intr...

The idea that cooperative groups out-compete less cooperative groups has been proposed as a theoretical possibility for the evolution of cooperation through cultural group selection. Previous studies have found an association between increased cooperation and exposure to inter-group violence, but most have not been able to identify the specific target of cooperation and are based on correlation...

Eyewitness testimony has been shown to be unreliable and susceptible to false memories. Whether eyewitness memory errors are influenced by the victim's group membership (relative to both the eyewitness and perpetrator) is underexplored. The current study used complementary behavioral and neuroimaging approaches to test the hypothesis that intragroup conflict heightens participants' susceptibili...

Individuals with generalized anxiety disorder (GAD) display poor emotional conflict adaptation, a cognitive control process requiring the adjustment of performance based on previous-trial conflict. It is unclear whether GAD-related conflict adaptation difficulties are present during tasks without emotionally-salient stimuli. We examined conflict adaptation using the N2 component of the event-re...

assistance. We would also like to thank Thomas Armentrout for his involvement in the project, Cindy Young for her data entry and analysis efforts, and Kelly Gable for her assistance in manuscript preparation. In this quasi-experimental study, we investigate value congruence and demographic dissimilarity among group members as factors which influence various types of conflict within workgroups. ...
