Hawthorne Effect


Health Economics

  • An improvement in productivity due to its observation. The effect was first noticed in the Hawthorne plant of Western Electric in Cicero, Illinois, where production increased not as a consequence of actual changes in working conditions but because there was a Harvard research team taking an active interest in working conditions in the plant, and management was also taking an interest. A type of confounding factor in experiments and trials that may lead to bias. The term is now used for any situation where the behaviour of the subjects being studied may be affected by the fact of their being studied.
