Abstract
This study explores one of the contributors to group composition - the basis on which people choose others with whom they want to work. We use a combined model to explore individual attributes, relational attributes, and data from participants in 33 small project groups were collected, some of which reflects individual participant characteristics and some which is social network data measuring the previous relationship between two participants. Our results suggest that when selecting future group members people are biased toward others of the same race, others who have a reputation for being competent and hardworking, and others with whom they have developed strong working relationships in the past. These results suggest that people strive for predictability when choosing future work group members.
