Abilene paradox management expert Jerry B. Harvey in his 1974 article "The Abilene Paradox: The Management of Agreement". The name of the phenomenon comes from an anecdote that Harvey uses in the article to elucidate the paradox: Ronald Sims writes that the Abilene paradox is similar to groupthink, but differs in significant ways, including that in groupthink individuals are not acting contrary to their conscious wishes and generally feel good about the decisions the group has reached. According to Sims, in the Abilene paradox, the individuals acting contrary to their own wishes are more likely to have negative feelings about the outcome.
A-group A-groups in . The following can be said about A-groups: A-group In mathematics, in the area of abstract algebra known as group theory, an A-group is a type of group that is similar to abelian groups. The groups were first studied in the 1940s by Philip Hall, and are still studied today. A great deal is known about their structure. An A-group is a finite group with the property that all of its Sylow subgroups are abelian. The term A-group was probably first used in , where attention was restricted to soluble A-groups. Hall's presentation was rather brief without proofs,
