"Bipolar groupthink": assessing groupthink tendencies in authentic work groups.

Research on regressive group processes such as Janis' (1982) "groupthink" phenomenon has rarely focused on work groups in authentic settings. In this study, teams from six different organisations (n = 308) were studied by using a groupthink questionnaire constructed in accordance with the symptoms of groupthink described by Janis. It was hypothesised that groupthink could be described as a bipolar construct identifying either an omnipotent or a depressive variant of a group's delusions about its own and other groups' features. The questionnaire showed reasonably good reliability as a whole and a factor analysis identified three factors in line with the proposed theoretical model in which the two different types of groupthink can be distinguished. We propose that any group might have a tendency or predisposition to react in either of the two directions during provocative circumstances. The six different organisations exhibited different types of groupthink to a varying degree. A religious sect was the one most characterised by omnipotent groupthink, while a technological company and a psychiatric team seemed to be the ones with most features of depressive groupthink.
