Pygmalion theory of Leadership is a model of SFP at work involving supervisory expectancy based on the pygmalion effect. This effect is a type of self-fulfilling prophecy (SFP) in which raising leader's expectations regarding subordinate performance boosts the group's performance. Managers who are led to demand more from their team, lead the team to better performance. There is some evidence that the SFP effect does exists.
