The Hawthorne Effect arises from the result of a study carried out between 1924-1927 in the Hawthorne plant of the Western Electric Company in Chicago, IL.
Over this three year period researches found that productivity was directly related to the workforces knowledge that they were being watched. It is also a motivating contributor of people trying to do better because they know they are being watched. Thus, observer interference became known as as the Hawthorne Effect.
This result has been documented over subsequent decades and results are constant, people change their behaviour when they "know" they are being watched.
Observer-Expectancy Effect
The Observer-Expectancy Effect is a cognitive bias found in science that occurs when a researcher expects a given result and therefore can unconsciously manipulate the research in order to find the expected result.
People tend to think of perception as a passive process. We hear, see, smell, taste or feel stimuli that impinge upon our senses. We think that if we are at all objective, we record what is actually there. Yet perception is demonstrably an active rather than a passive process; it constructs rather than records "reality." It is a process of inference in which people construct their own version of reality on the basis of information provided through the five senses.
Video Mystery Shopping is the perfect tool for overcoming both off these effects because of the equipment we use, people never know they are being watched. And because video has no senses to overcome, there is no perception of reality, only accurate intelligence of the surroundings and activities.
