The Hawthorne Effect is a phenomenon that occurs when people modify their behavior due to the fact that they are being observed. It is named after the Hawthorne Works, a factory in Cicero, Illinois, where a series of experiments were conducted in the 1920s and 1930s to study the effects of different working conditions on productivity. The Hawthorne Effect has been studied extensively in the fields of psychology and sociology, and it has been found to have a significant impact on how people behave in certain situations.


Examples: Examples of the Hawthorne Effect include people working harder when they know they are being watched, and people being more cooperative when they know they are being observed.


Effects: The Hawthorne Effect has been found to have a significant impact on how people behave in certain situations. It can lead to increased productivity, improved cooperation, and better performance. It can also lead to people feeling more motivated and engaged in their work.
