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.
Free abelian group with finitely many nonzero values; for this functional representation, the group operation is the pointwise addition of functions. Every set "B" has a free abelian group with "B" as its basis. This group is unique in the sense that every two free abelian groups with the same basis are isomorphic. Instead of constructing it by describing its individual elements, a free group with basis "B" may be constructed as a direct sum of copies of the additive group of the integers, with one copy per member of "B". Alternatively, the free abelian group with basis "B" may be described by
