- Reviewed in the United States on June 12, 2002This 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.
- Reviewed in the United States on January 14, 2015first flipped thru it 12 years ago when my oldest son took a political science course at harvard, my youngest son has recently taken a similar course at yale and so I had to buy the book! very insightful and well written - proves the old adage to be true that we learn little from history!
- Reviewed in the United States on February 9, 2015Interesting. I plan to quote some of this in my book. Complements the book "From Good to Great," in that both agree the best way to get strong management performance is to get everyone debating until the leader is ready to make his call. It describes what's happening in our public schools rather well.
- Reviewed in the United States on December 6, 2013This 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!
- Reviewed in the United States on October 16, 2011With 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.
- Reviewed in the United States on January 24, 2013It's a classic academic writing. Informative for anyone looking for more effective decision-making and conflict issues in groups and organizations.
- Reviewed in the United States on May 24, 2018Will open your eyes to why so many get involved without really knowing what the leading is advocating.
- Reviewed in the United States on December 31, 2015Used a lot in MPA course. Reference tool and easy to read...wanted to keep but parted ways with, for more book funds.

B. PennReviewed in Canada on October 15, 20205.0 out of 5 stars THE THEME IS PREFECTLY SHOWING WHAT HAPPENS IN THIS TIME OF COVID-19
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
Mark KoelmanReviewed in Germany on September 5, 20144.0 out of 5 stars Great seller
Good price and fast shipment, I highly recommend this seller if you are looking for used books, A+. Would buy again.
Erik ElgersmaReviewed in the United Kingdom on March 24, 20144.0 out of 5 stars great reading, also applicable outside the Government arena
Janis researches several cases of decision-making in great detail, distilling factors that together in some cases contribute to Groupthink as source of fiascoes. Old cases perhaps but still actual

その他大勢Reviewed in Japan on July 4, 20045.0 out of 5 stars 異常な組織の研究
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。
