In the 1920’s and 30’s, the nation was swept up in the Efficiency Movement, an effort to rid every aspect of human life of waste and unproductive activity. Researchers were dispatched to factory floors, classrooms, and even family living rooms with the mission of finding the optimal formula for efficient and productive work, a formula supported by the new excitement over science and experimentation. Within this context, a study was conducted at the Hawthorne Works, a factory making telephone equipment for Western Electric, to determine the optimal illumination level for worker productivity. These experiments went on for eight years, and ended with little fanfare. Decades later, however, Henry A. Landsberger revisited these studies, discovering a pattern that revealed more about human nature than about workplace illumination. This pattern still impacts research today, where it is known as the Hawthone effect.
