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.
Hausdorff paradox that if two open subsets of the plane (or the real line) are equi-decomposable then they have equal area. Hausdorff paradox The Hausdorff paradox is a paradox in mathematics named after Felix Hausdorff. It involves the sphere "S" (a 2-dimensional sphere in "R"). It states that if a certain countable subset is removed from "S", then the remainder can be divided into three disjoint subsets "A", "B" and "C" such that "A", "B", "C" and "B" ∪ "C" are all congruent. In particular, it follows that on "S" there is no finitely additive measure defined on all subsets such that
