An Interactive Input-Process-Output Model of Social Influence in Decision-Making Groups

The first goal of this article is to demonstrate that the dichotomy between informational and normative influence in group decision making is long outdated and should be replaced with a distinction among compliance, comparison, and argumentation influence processes. The second goal of this article is to use this distinction as the basis for a literature review of the impact of various input factors on social influence during small group discussion. The third goal of this article is to present the Simplified Model of Group Social Influence Processes, an interactive input-process-output model relevant to decision-making groups. The article ends with a discussion of the implications of this model for future research and further model development.
