问题                       "Group Decision Making"
    Advantages of Group Decision Making
    → Committees, task forces, and ad hoc groups are frequently assigned to identify and recommend decision alternatives or, in some cases, to actually make important decisions. In essence, a group is a tool that can focus the experience and expertise of several people on a particular problem or situation. Thus, a group offers the advantage of greater total knowledge. Groups accumulate more information, knowledge, and facts than individuals and often consider more alternatives. Each person in the group is able to draw on his or her unique education, experience, insights, and other resources and contribute those to the group. The varied backgrounds, training levels, and expertise of group members also help overcome tunnel vision by enabling the group to view the problem in more than one way.
    → Participation in group decision making usually leads to higher member satisfaction. People tend to accept a decision more readily and to be better satisfied with it when they have participated in making that decision. In addition, people will better understand and be more committed to a decision in which they have had a say than to a decision made for them. As a result, such a decision is more likely to be implemented successfully.
    Disadvantages of Group Decision Making
    → While groups have many potential benefits, we all know that they can also be frustrating. A One obvious disadvantage of group decision making is the timerequired to make a decision.B  The time needed for group discussion and the associated compromising and selecting of a decision alternative can be considerable. C Time costs money, so a waste of time becomes a disadvantage if a decision made by a group could have been made just as effectively by an individual working alone.D  Consequently, group decisions should be avoided when speed and efficiency are the primary considerations.
    A second disadvantage is that the group discussion may be dominated by an individual or subgroup. Effectiveness can be reduced if one individual, such as the group leader, dominates the discussion by talking too much or being closed to other points of view. Some group leaders try to control the group and provide the major input. Such dominance can stifle other group members’ willingness to participate and could cause decision alternatives to be ignored or overlooked. All group members need to be encouraged and permitted to contribute.
    → Another disadvantage of group decision making is that members may be less concerned with the group’s goals than with their own personal goals. They may become so sidetracked in trying to win an argument that they forget about group performance. On the other hand, a group may try too hard to compromise and consequently may not make optimal decisions. Sometimes this stems from the desire to maintain friendships and avoid disagreements. Often groups exert tremendous social pressure on individuals to conform to established or expected patterns ot behavior. Especially when they are dealing with important and controversial issues, interacting groups may be prone to a phenomenon called groupthink.
    → Groupthink is an agreement-at-any-cost mentality that results in ineffective group decision making. It occurs when groups are highly cohesive, have highly directive leaders, are insulated so they have no clear ways to get objective information, and—because they lack outside information—have little hope that a better solution might be found than the one proposed by the leader or other influential group members. These conditions foster the illusion that the group is invulnerable, right, and more moral than outsiders. They also encourage the development of self-appointed "mind guards" who bring pressure on dissenters. In such situations, decisions—often important decisions—are made without consideration of alternative frames or alternative options. It is difficult to imagine conditions more conducive to poor decision making and wrong decisions.
    Recent research indicates that groupthink may also result when group members have preconceived ideas about how a problem should be solved. Under these conditions, the team may not examine a full range of decision alternatives, or it may discount or avoid information that threatens its preconceived choice.
According to paragraph 2, why do group decisions tend to be more successful?
选项 A、When more people are involved, there are more ideas from which to choose.
B、People are more accepting of decisions when they have been involved in them.
C、Implementing ideas is easier with a large number of people to help.
D、People like to be participants in decisions that are successful.
答案B
解析 "... people will... be more committed to a decision in which they have had a say than to a decision made for them." Choice A is true, but more ideas do not explain why the decisions are successful. Choice C is not correct because the help provided by a large number of people is not mentioned in the passage as an advantage during implementation. Choice D is not correct because implementation is successful in group decisions, but the decisions themselves may or may not be successful.
