In 1924 America's National Research Council sent two engineers to supervise a series of industrial experiments at a large telephone-parts factory called the Hawthorne Plant near Chicago. It hoped they would learn how stop-floor lighting workers' productivity. Instead, the studies ended giving their name to the "Hawthorne effect", the extremely influential idea that the very to being experimented upon changed subjects' behavior.
The idea arose because of the behavior of the women in the Hawthorne plant. According to of the experiments, their hourly output rose when lighting was increased, but also when it was dimmed. It did not what was done in the experiment; something was changed, productivity rose. A(n) that they were being experimented upon seemed to be to alter workers' behavior itself.
After several decades, the same data were to econometric the analysis. Hawthorne experiments has another surprise store the descriptions on record, no systematic was found that levels of productivity were related to changes in lighting.
It turns out that peculiar way of conducting the experiments may be have let to interpretation of what happed. , lighting was always changed on a Sunday. When work started again on Monday, output rose compared with the previous Saturday and to rise for the next couple of days. , a comparison with data for weeks when there was no experimentation showed that output always went up on Monday, workers to be diligent for the first few days of the week in any case, before a plateau and then slackening off. This suggests that the alleged "Hawthorne effect" is hard to pin down.
