Managing Self-Uncertainty Through Group Identification

Hogg's uncertainty-identity theory (UIT) is briefly described to identify similarities and differences to Van den Bos's uncertainty management model (UMM). Against a background of significant overlap in scope, mission and concepts, four differences are identified: First, UMM is primarily a theory of motivation for ideological conviction; UIT is a theory of motivation for group identification. Second, UMM talks about personal uncertainty; UIT talks about self-uncertainty—the implications of this difference in terminology are discussed. Third, both theories focus on uncertainty about self; but UIT also focuses on an array of moderating variables that affect the experience of uncertainty and the way in which self-uncertainty is reduced. Finally, and most significantly, UMM does not detail the process of uncertainty reduction; UIT does—it specifies social cognitive processes that reduce self-uncertainty and contexts that direct these processes toward “normal” group phenomena or toward more extreme group phenomena.
