Rosenthal effect

the situation in which an investigator’s expectations about the outcome of a given study unwittingly affect the actual study outcome.

This term is often used synonymously with experimenter expectancy effect and self-fulfilling prophecy. See also demand characteristics. [Robert Rosenthal (1933–  ), U.S. psychologist]
