Definition
Meaning
A psychological phenomenon where individuals modify or improve their behavior when they know they are being observed or studied.
The alteration of behavior by the subjects of a study due to their awareness of being observed, which can lead to skewed results and questions about the validity of research findings, particularly in workplace, educational, or social science contexts.
Linguistics
Semantic Notes
Refers specifically to a research artifact or bias, not general self-consciousness. It is a proper noun derived from a specific series of studies (Hawthorne Works of Western Electric, 1924-1932). The term describes the experimental confounding variable itself.

FAQ
Frequently Asked Questions
It is considered a confounding variable, a threat to internal validity. It's not 'bad' in an ethical sense, but it is a methodological problem that researchers must design their studies to control for or acknowledge.
Yes, the core idea—people changing behavior when they know they're being watched—applies in workplaces, schools, and under surveillance. However, the term is most precisely used in a research methodology context.
It was named after the Hawthorne Works plant in Chicago where Western Electric and researchers from Harvard (like Elton Mayo) conducted productivity studies from 1924-1932. The effect was inferred from the unexpected results of these studies.
The Hawthorne effect is about behavior change due to observation/special attention. The placebo effect is a physiological or psychological improvement due to the belief in receiving an effective treatment, not necessarily observation.
