hypermoron

The cause is morinoia, habit-mindedness; the type of person is the moron, in three grades, the morose, the amiable and the hypermoron, or near-normal.

Mrs. Stoner devised six classes of people. In ascending order of value they were idiots; destructionists; morons; hypermorons (in which class she put most people); geniuses (who were creative); and progressionists (who could get things done in business and related fields).
