Groupthink is a phenomenon that acts as a barrier to good governance. It is a form of self censorship that causes a failure of critical thinking when the desire for group consensus overrides ones ability or desire to critique / challenge a position, present alternatives or express an unpopular opinion. It is often in play when groups reach consensus without critically examining an issue; there is an illusion of agreement or consensus: “it appears as everyone agrees, so let’s move on.”
It occurs when there is a high level of group cohesion or a strong persuasive leader who articulates his or her opinion, especially when the opinion is expressed early in the discussion. It also occurs when groups are isolated from contrary opinions.
Board meetings are perfect breeding grounds for groupthink.
