We investigate whether and how the personality of the coworkers with whom an individual interacts helps explain the extent to which the individual comes to occupy advantageous positions in social networks. We suggest that differences in self-monitoring personality affect social structure beyond the reach of the individual. We test this prediction in two studies. In Study 1, we use cross-sectional data on advice relations in an organization to show that self-monitoring is associated with network popularity and homophily: high self-monitors are sought for advice mainly from highs, and low self-monitors from lows, although high self-monitors receive more advice requests overall. In Study 2, we use longitudinal data on advice relations within a cohort of young-professionals in a post-graduate program, to show that high self-monitors come to occupy network brokerage roles to the extent that they are sought for advice by other high self-monitors. This happens, we suggest, because their high self-monitoring contacts tend to remain unconnected from each other. At the same time, the extent to which high self-monitors are sought for advice by low self-monitors tends to explain the possibility that even the highs may remain embedded in closed networks. This happens, we suggest, because their low self-monitoring contacts are more likely to interact with each other.
