Why a Study of 5 Working Women in the 1920s Changed Your Work Life

In the 1920s researchers descended on the Western Electric Company's Hawthorne Works in Cicero, Illinois. Their mission was to look at how environmental conditions such as lighting levels made workers more or less productive.

But the research quickly uncovered a paradox. When illumination was increased, productivity went up. But when the light was decreased, even down to the level of moonlight, productivity increased again.

What was going on here?

The answers changed the direction of both sociological and management research. At its highest level the Hawthorne Effect is simply a recognition that if you are observed, your behavior will change. (Researchers still debate whether this focused attention leads to productivity increases, however).

But the studies were also one of the first times that workers were viewed as part of a larger social system, not just as unfeeling automatons. This research has led modern-day companies to look less for ways to control employees and more at methods of unleashing their creativity.

The BBC recently did a report on the Hawthorne Studies, including a visit to Harvard Business School, where many of the original research materials are stored. ( Harvard Business School researchers Elton Mayo and Fritz Roethlisberger were instrumental in the research.)
