How can an organisation minimise the risk of groupthink?
1. Groupthink can be minimised by minimising antecedents to it, for example, by ensuring:
1. Low levels of group cohesiveness;
2. Organisational structure which fosters openness, leader impartiality, procedural norms and member diversity;
3. Situational contexts like high group efficacy and low stress.
2. Low levels of group cohesiveness can be encouraged by avoiding self-perpetuating mechanisms of the group, for example, avoiding automatic membership renewals, so there is rotation of new members into the group, old members out.
3. Another step to reduce group cohesiveness is participation of specialist/expert outsiders or internal audit in group decision processes so as to disrupt informal members’ alliances or usual group reaction patterns.
4. Group processes should support openness or whistleblowing by team members including, for example, a member acts as a devil’s advocate to expressly challenge majority suggestions and generate other perspectives. A devil advocate in groups of cultural homogeneity could be a bicultural individual of low bicultural identity integration (BII). Biculturals with low BII are more comfortable to dissent to norms of the prime culture of the group.
5. Inclusion of a bi-sector or bi-discipline individual into a group or team with all other members in one of the sectors or disciplines of the bi-sector/bi-discipline individual may help to generate different options and better processing of information relating to those options. However, like other teams of diversity (different genders, inter-generational or multicultural members), multi-sector teams and multidiscipline teams require effective communication processes for optimal understanding of each other and to optimise divergent thinking for creative problem-solving of a diverse team.
6. In temporary organisations, like a project team, impartial project managers should hold sufficient power or authority (in procedural norms) to balance freedom, efficiency and speed in decisions, as required by context, to circumvent poor decision-making from an isolated specialist team with high congruence of values.
7. The size of a group should be ten or less members so members are more likely to retain personal responsibility for decisions, that is not abdicate responsibility, and so members take steps to ensure effective information processing for effective decision-making. Group norms are to ensure discussion is not dominated by one group member, for example, questions in focus groups be carefully compiled (mostly open-ended) and asked by an impartial facilitator to minimise individual domination and group conformity.
8. Groups with a holistic mix of team participation, communication and thinking styles, as well as methods of communication with each other (such as visual, verbal and tactile), will increase group efficacy and in turn effective processing of information towards better quality decisions.
9. Groupthink can also be minimised by the group taking steps to avoid group members supporting a perceived group preference or avoid concurrence seeking (concurrence seeking being the second causal link in the groupthink process).
10. One such step is for impartial group leaders to seek all members’ input and refrain from giving their own opinions, during initial group discussions. Group members are encouraged to present options without specific recommendations and members discuss negative elements of options before canvassing positive elements.
11. Additionally it can be minimised by taking steps to overcome influences to symptoms of groupthink (the third causal link in the groupthink process). Firstly, the group takes steps to ensure the group is real in its belief of the group’s abilities and group members understand the group’s views are only one viewpoint of many viewpoints. For example, audit of skills, strengths and weaknesses of group members, will disclose gaps in skills skills for effective information processing and decision-making. Diversity management aids accommodation of many viewpoints. Organisational processes which require risk management and contingency plans will focus group members on examination of risks and triggers to failure.
12. Organisation introduces code of ethics, ethics officer and organisation-wide ethics training (and retraining) programmes. In other words, the organisation introduces procedural norms for organisational benefit (not personal gain) which are to be mentored/overseen by an organisational expert (group outsider). This action is especially important for maintenance of organisational ethics if group members would otherwise culturally diffuse responsibility for unethical decision-making.
13. Secondly, the group takes steps to ensure the group remains open-minded so group members do not rationalise information that contradicts expectations or assumptions and do not stereotype the views of competitors and other outsiders as inferior. The leader assigns the role of critical evaluator to each member. There is constructive critical reflection of previous learnings and past situation or experiences to challenge prior/existing assumptions. The leader should ensure a sizeable block of time is set aside to survey warning signals from rivals; leader and group members construct alternative scenarios of rivals’ intentions.
14. Thirdly, the group takes steps to deter pressure towards conformity of group decisions. Group procedural norms encourage structured decision making: to deter self-censorship, illusion of unanimity or harmony, direct pressure on dissenters to concede to solutions and self-appointed mindguards.
15. Some tools for point 14 are:
1. Group norms require the group chair to canvass each group member to voice opinion before any decision is put to a vote (or secret ballot), as used in Board meetings (or jury rooms)
2. Group norms supports accountability of group members who are required to justify their suggestions
3. Multiple groups study the same issue and/or bolster internal audit reviews of decision processes
