Groupthink: Groupthink is a psychological phenomenon that occurs when a group of people strive for consensus without critically evaluating the consequences of their decisions. It is often caused by a desire to conform or to avoid conflict. Groupthink can lead to irrational or disastrous decisions, as members of the group may overlook or suppress dissenting opinions. See also Group behavior, Conformity.

Marlene Turner on Groupthink - Dictionary of Arguments

Haslam I 190
Group think /social identity/Pratkanis/Turner: Marlene Turner and Anthony Pratkanis proposed a social identity maintenance model [for group think]. Their model retained consensus-seeking at the heart of groupthink, but emphasized consensus of a particular type – namely, consensus around ‘a shared positive view of the functioning of the group’ (1998a(1): 212). They posited that the desire to achieve this type of consensus arises from two interactive (not additive) factors: (cohesion and collective threat, which in combination induce behaviours that do a better job of protecting the group’s self-image than ensuring sound decisions.
Haslam I 191
Cohesion/Pratkanis/Turner: Turner and Pratkanis (1998a)(1) drew on social identity and self-categorization theories (Abrams and Hogg, 1988(2); Hornsey, 2008(3); Tajfel and Turner, 1979)(4) to offer a particular definition of cohesion. Specifically, they suggest that cohesion arises when members identify with their group, such that membership in the group represents an important part of their self-concept. Thus identified, individuals seek to maintain a positive image of their group and are more reactive to potential threats to that image. >Goals/Pratkanis/Turner.
