Deviance in organizational group decision-making: The role of information processing, confidence, and elaboration

Abstract

While deviance can foster innovation within groups, research does not always find beneficial effects. The current studies provide an information processing account of the influence of deviants in group decision-making. We predicted deviants would undermine decision confidence and promote greater elaboration when tasks were difficult. Study 1 manipulated the strength (systematic cue) and gender (heuristic cue) of a job applicant to investigate the effect of a deviant in a difficult task. As predicted, a deviant was associated with lowered confidence, greater elaboration, and higher decision quality, but also decreased group cohesion and task satisfaction. Study 2 investigated the effect of a deviant during a simple task and found the same decrease in group cohesion and task satisfaction, but this time with no increase in elaboration or improvement in decision outcome quality. Results indicate that deviance, when seen as justified, has the potential to reduce the occurrence of prejudice and produce fairer decision outcomes during decision-making.
