Formal probability models of group decision
making imply that the normative influence of large opinion factions tends to
have a negative impact on the quality of decisions in difficult tasks and a
positive impact in easy tasks that many people solve correctly. Consequently,
an informative intervention (INFO) was developed that advises group
members to evaluate task difficulty and to react correspondingly to normative
majority or plurality influence. In the study, groups of 5 persons had to solve
2 types of intellective tasks: knowledge questions and logic problems. Compared
to control groups, group members in the INFO condition were less overconfident,
and achieved more correct group decisions.
