This phenomenon is called The Expectancy Effect.
<h3>What is
The Expectancy Effect?</h3>
The Expectancy Effect is When someone expects a given result, that expectation unconsciously affects the outcome or report of the expected result.
When a participant expects to have a certain kind of outcome they will, without realizing it, change their actions and behaviors to actually get this exact outcome.
In scientific research and psychotherapy, the subject-expectancy effect, is a form of reactivity that occurs when a research subject expects a given result and therefore unconsciously affects the outcome, or reports the expected result. Because this effect can significantly bias the results of experiments (especially on human subjects), double-blind methodology is used to eliminate the effect.
Therefore, we can conclude that the correct option is D.
