If a researcher does not have a clear operational definition of the behavior he is studying, he might experience observer bias. Observer bias is the tendency for an observer to influence the behavior of the subject being observed. This can happen when the observer has a preconceived notion about the subject's behavior, or when the observer's presence changes the subject's behavior.
