Even though no one in the family actually wants to go to Abilene, they all decide to go anyway. They spend a miserable afternoon together eating at a place they all hated and doing what they did NOT want to do.
According to J. B. Harvey, The Abilene Paradox occurs when:
Groups take action that contradicts what all or most of the group members really want to do.
Group members have serious concerns about a certain decision, policy, system, etc, and fail to speak up.
