Abilene paradox
In an Abilene paradox a group of people collectively decide on a course of action that is counter to the preferences of many (or all) of the individuals in the group. It involves a common breakdown of group communication in which each member mistakenly believes that their own preferences are counter to the group's and, therefore, does not raise objections. A common phrase relating to the Abilene Paradox is a desire not to "rock the boat." This differs from groupthink in that the Abilene paradox is characterized by an inability to manage agreement.
