Abilene paradox

False consensus due to communication failure

The Abilene paradox is a collective fallacy, in which a group of people collectively decide on a course of action that is counter to the preferences of most or all individuals in the group, while each individual believes it to be aligned with the preferences of most of the others. It involves a 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. They even go so far as to state support for an outcome they do not want.
