Echo Chamber

The tendency of members of a group to reinforce each other's views and not to contradict each other because there is little or no information presented from outside the group. An echo chamber is dangerous in business as one member may not see a flaw in another's thinking or may be afraid to point it out. However, the term is most commonly used in media to describe a self-reinforcing story. See also: Groupism.
