When you fill a room with smart, capable people, why do decisions sometimes go so wrong? Janis has one hypothesis: They can become victims of "groupthink." Groupthink refers to (Page 9) ". . .deterioration of mental efficiency, reality testing, and moral judgment that results from in-group pressures." Janis describes the dynamic thus (Page 5):
"In studies of social clubs and other small groups, conformity pressures have frequently been observed. Whenever a member says something that sounds out of line with the group's norms, the other members at first increase their communication with the deviant. . .But if they fail after repeated attempts, the amount of communication they direct toward the deviant decreases markedly. The members begin to exclude him. . . . [T]he more cohesive the group and the more relevant the issues to the goals of the group, the greater is the inclination of the members to reject a nonconformist." In short, groups will tend to reinforce their own views and reject the words of those who disagree. In this case, members of the group become "conformist to some conformity."
Janis uses several case studies of what he considers to be "groupthink"--The Bay of Pigs invasion, the escalation of the Korean War in 1950, the attack on Pearl Harbor while the "fortress slept," and escalation of the Viet Nam War. In each instance, according to Janis, top decision-makers walled themselves off from dissenting voices and tended to reinforce one another's preexisting positions. In counterpoint are two successes, where groupthink did not triumph--the Cuban Missile Crisis and the development of the Marshall Plan.
The thesis may be a bit simplistic, but it is abundantly clear from this book and from what we see around us that groupthink can be problematic. I suspect that one could argue that decisions such as the following, which appear to be one poor decision on top of another, may be examples of this phenomenon at work: Jimmy Carter's failed effort at a rescue mission to liberate the hostages in Iran; the plan to attack Iraq without any serious planning for what would happen afterwards; the dividing up of the Middle East into artificial countries after World War I. Readers can try to think of other examples, too--whether in politics, in their workplace, or in any other location where group decision-making takes place.
What to do? Some point out Franklin Roosevelt's style of getting input from many different advisors, this hearing an array of voices (although in the run up to Pearl Harbor, one doesn't find much of this in the President's Inner Circle). In the last chapter, Janis provides a number of suggestions as to how decision-making can be structured so as to reduce the odds of groupthink occurring (e.g., don't have the leader express preferences until all voices have been heard; have the leader encourage questions to be raised and then pay attention to those who dissent and taker their arguments seriously). These may not be earth shaking ideas, but they would, in Janis' view, at least reduce the odds of dire consequences coming from groupthink.
The first version of this book came out in the early 1970s, but it is still timely today.

This classic of social psychology is based on the idea that people in groups might think differently and by implication less well than they would have thought as individuals on the same issue at the same time. That is probably true for some groups at some times just as it is also probably true that some groups at some times might actually think better than any individual member of that group. In fact, most of the evidence cited in this book supports the idea that group thinking, like thinking in general, goes awry when there is a failure to evaluate all the available evidence for relevance and sufficiency in quality, quantity, and weight. When a group or an individual fails to evaluate the evidence, then the group or the individual reaches a decision not justified by the data and vice versa. Failure to perceive the reality, as demonstrated by evidence, has tremendous adverse consequences as is so well illustrated by Janis' detailed account of the Bay of Pigs fiasco. Correct evaluation of the data, as demonstrated by evidence, has tremendous beneficial consequences as is so well illustrated by Janis' detailed account of the Cuban Misssile crisis. In fact, the fascinating parts of this book relate to the detailed analysis of group decisions in history, a reason enough to buy and read this fine work despite the price. Incidentally, Gilbert Murray has sought to explain the group cohesiveness thing by another myth which he calls "the groping of a lonely-souled gregarious animal to find its herd or its herd-leader." But however we attempt to account for the craving for unity in some groups, it seems to be a deeply rooted human irrational demand. Like James' "sentiment of rationality," it is a sentiment and a need long before it is justified by any discoverable facts. Our duty is to be on guard against it. Groupthink, this classic book, should boost our defenses.

I originally read this book in college as part of a course. The term "Groupthink" is as appropriate now as then; maybe even more so - with the movement of political correctness run-amok. This book should be required reading in all colleges.

This is a fascinating read. We see the results of group think everywhere and around us every day. Truthfully, I think this book shoots holes in the superiority of theory of team judgement. If you work in a team environment and understand "group think", it is possible to enhance your influence on the outcome of the decision process. You can have fun with this!

With some great case analyzes this book make the point on why some great people working together can fail. The only problem is that the way the cases as described and analyzed are very repetitive, after the first four chapters you already got all the points and the book start to walk in circles.

Think tanks in high echelons do 'group-think' about utopias. This happens now in this agony of the Covid-19 Fraud too. The most wealthy elite have used group think to implement the Covid measures . They want to create an UTOPIA, but when all measures are not based on what is living in the people's hearts, groupthink by elites will fail

異常な組織の研究
Reviewed in Japan on July 4, 2004Verified Purchase
異常な意思決定について、アメリカ政府の過去の失敗事例から理論を作り出そうとしている。2章から7章まで、キューバ革命のアメリカの対応や真珠湾攻撃のアメリカの上層部の対応についてなどが、ケーススタディーとして描かれている。
何のために意思決定を行うのかについて議論することが乏しくなり、意思決定者たちが「居心地が良い」内容に物事を進めていこうとする傾向がある。これは、著者によると企業の意思決定でも生じる可能性があるとしている。
この論文でとりあげられているケーススタディーは、戦争あるいは戦争に準ずる国家の危機における異常な意思決定であり、すべての異常な意思決定に関して適応できるとは思えない。特に、意思決定の対象となる「敵」の存在は、意思決定者たちの集団凝集性を高め、仲間意識を強くすることが考えられる。この論文でもGroupthinkが生じる可能性は、仲間意識が高くなるほど生じると論じている。しかも、意識されている敵は、ステレオタイプで誇張される傾向にあるという。
つまり、グループの中で変わった意思決定者が存在すると、多数派がこの変り者に対してcommunicationを増やし、その意思決定の変更をうながすように説得する。この説得に失敗すると、communicationは減少し、変人をのけものにしようとする。こうして、「居心地の良さ」を高めようとする。このステレオタイプに対して、異議を申し立てるものが変人となる。
変人の除去については、あらゆる組織あるいはコミュニティで生じることであろう。しかし、日本企業のように排除は可能性が高い組織の中では、なかなかうまくいかないのではなかろうか。このあたりは検討課題である。
