Group Decision Making

Brief Presentation:
Does the group always perform better than the individual? the answer seems to be obvious, but it isn't. Groups has to face several challenges in order to arrive at a high quality decision:
- the  distribution of information among group members may give rise to several types of bias. Informational bias and Preferential bias for example (stasser & titus, 1985).
- Group decision often reflect the common knowledge shared by members before discussion and not the diverse knowledge emanating from their unique perspective. The failure of groups could be due in part to how members construe their decision-making task (Stasser and stewart, 1992).
- confirmation bias, which is requesting information which will support a preselected alternative (Schulz-hardt et al., 2000).
- group norms may influence the quality of group decisions independent of factors relating to group cohesion. Formation of critical versus consensual group norms that may boost or deteriorate the quality of group decisions (postmes & spears, 2001)
- effective group decision making is contingent on the satisfaction of critical task requirements. proponents of this theoretical position suggest that groups are more likely to arrive at a high quality choice when they successfully satisfy the critical requirements of the task (hirokawa, 1988).
