ABSTRACTThe problem of reliability in the behavioral experiment appears to be due to the dynamic nature of the subject matter of the behavioral sciences resulting in interactions between the subjects (Ss), the experimenter (E), and the experimental situation (SIT). Both theEandSITelicit varying degrees of nonassessable conformity in theSs' behavior. TheStends to preserve the behavior that the perceives is expected of him—theS's conformity obligation. Just as natural and physical sciences have relied upon inferences built upon many intersecting and overlapping observations (a method calledconverging operationalism), behavioral science could apply this method to resolve the difficulties of theEeffect and the effects of theSIT, since both affect the reliability of the psychological experiment. Empirical factors that determine under what circumstances theEandSITsignificantly affect theS's experimental behavior are reviewe
