Managers can use a variety of techniques in group decision-making situations to
counteract situations in which the group is suffering from groupthink or cognitive biases.
Two such techniques have been shown to be especially useful in such situations. Discuss
these two techniques.
The two techniques that have been found to be most useful in groups suffering from
groupthink or cognitive biases are devil’s advocacy and diversity.
Devil’s advocacy is a critical analysis of a preferred alternative to ascertain its strengths
and weaknesses before it is implemented. Typically one member of the decision-making
group plays the role of devil’s advocate. The devil’s advocate critiques and challenges the
way the group evaluated alternatives and chose one over the others. The purpose of
devil’s advocacy is to identify all the reasons that might make the preferred alternative
unacceptable. In this way, decision makers can be made aware of the possible perils of
recommended courses of action.
Another way to improve group decision making is to promote diversity in decision-making
groups. Bringing together managers of both genders from various ethnic, national, and
functional backgrounds broadens the range of life experiences and opinions that group
members can draw on as they generate, assess, and choose among alternatives.
