The Effects of Expertise and Social Status on Team Member Influence and the Moderating Roles of Intragroup Conflicts

Drawing on expectation states theory and expertise utilization literature, we examine the effects of team members' actual expertise and social status on the degree of influence they exert over team processes via perceived expertise. We also explore the conditions under which teams rely on perceived expertise versus social status in determining influence relationships in teams. To do so, we present a contingency model in which the salience of expertise and social status depends on the types of intragroup conflicts. Using multiwave survey data from 50 student project teams with 320 members at a large national research institute located in South Korea, we found that both actual expertise and social status had direct and indirect effects on member influence through perceived expertise. Furthermore, perceived expertise at the early stage of team projects is driven by social status, whereas perceived expertise at the later stage of a team project is mainly driven by actual expertise. Finally, we found that members who are being perceived as experts are more influential when task conflict is high or when relationship conflict is low. We discuss the implications of these findings for research and practice.
