Theory says if we set high expectations, we'll perform to them. Thus, if a supervisor is told that a work group contains individuals with high achievement potential, this information may get translated into high expectations of the supervisor and he/she may set high goals and objectives for the group (that is, higher goals and objectives than would otherwise be set). With high expectations and goals, group members may respond with unusually strong effort and meet the high goals and objectives. Why? How is it possible that we could use self-fulfilling prophecies to improve a workgroup
