「釋義」
團體在決策中很容易誤入歧途，這種現(xiàn)象稱為“團體迷思”。 美國心理學(xué)家歐文·詹尼斯通過實驗發(fā)現(xiàn)，封閉的團體討論會產(chǎn)生簡單化和模式化思想。具體到一個團隊在做決策過程中，由于成員傾向使自己的觀點與團體一致，會使決策參與者不能進行客觀分析，結(jié)果造成團體決策缺乏智慧。

「應(yīng)用場景」
團體在決策中很容易誤入歧途，美國心理學(xué)家歐文·詹尼斯把這種現(xiàn)象稱為“團體迷思”。團體犯錯有兩大原因：一是與信息信號有關(guān)。人們具有互相學(xué)習的本能，團體的錯誤往往源于一些成員接收了他人的錯誤信號。二是與聲譽壓力有關(guān)：不想挨罰或避免與他人意見相左，也使得人們噤聲或人云亦云。尤其是在他人獨具權(quán)威或大權(quán)在握時，與他們意見相左會帶來嚴重后果。
“Groupthink” is the term most often applied to the tendency of groups to go astray. Popularized in the early 1970s by the psychologist Irving Janis, it has deservedly entered the popular lexicon.

Groups err for two main reasons. The first involves informational signals. Naturally enough, people learn from one another; the problem is that groups often go wrong when some members receive incorrect signals from other members. The second involves reputational pressures, which lead people to silence themselves or change their views in order to avoid some penalty—often, merely the disapproval of others. But if those others have special authority or wield power, their disapproval can produce serious personal consequences.
