Status, Faction Sizes, and Social Influence: Testing the Theoretical Mechanism.

With two experiments the authors test and find support for the argument that in small, collectively oriented task groups, status affects social influence the most when the distribution of opinions reduces the least uncertainty. Moreover, they demonstrate that people use the distribution of both status and opinions to reduce uncertainty about the task on which they are working and that this, in turn, promotes social influence. Experiment 1 illustrates that, regardless of the group's sex composition, basis for status differentiation, or size of the group, uncertainty reduction mediates a significant share of the effect of status and opinions on social influence. Experiment 2 confirms that the effect of the distribution of both status and opinions on social influence is weaker as the task becomes more certain. These findings inform discussion about how status affects certainty in task groups and what this potentially means for organizational settings and sociological theory more generally.
