Final answer:
The false statement is that social expectancies have no impact on individual behavior; in fact, they have a significant influence as demonstrated by social psychology studies.
Step-by-step explanation:
The FALSE statement concerning the study on social expectancies is "C) The results of the study showed that social expectancies have no impact on individual behavior." By definition, social expectancies are the behaviors or actions anticipated in a given social context, and they do significantly influence behavior. In fact, social psychology studies, such as the Stanford prison experiment, illustrate how powerful the influence of social roles, norms, and contexts can be on individual behavior. This field explores how the presence of others, and the expectancies in different social settings, dictate the actions of individuals.
