Observers Expectancy Effect | Robert Rosenthal and Kermit Fode | 1963 | Stanford University.

<p>Imaging being a researcher who just discovered the medication to a certain disease and you decide to try on two separate groups; test and control group. You expect concrete results from the test group rather than the control one. How do you think these expectations might affect the actual experiment ?</p> <p>The observer expectancy effect, also known as the experimenter expectancy effect, refers to how the perceived expectations of an observer can influence the people being observed. For example, in our case above, you&rsquo;ll probably expect test group participants receiving the medication to feel better than those in the. control group.
