Teacher expectations can shape student results, though the Pygmalion effect is still debated
The Pygmalion effect is the idea that other people's expectations of a person can shape how that person performs. It takes its name from the Greek myth of the sculptor Pygmalion, who fell in love with his statue and watched it come to life. In 1968 the psychologists Robert Rosenthal and Lenore Jacobson argued in Pygmalion in the Classroom that teachers' expectations of students affect their progress: high expectations led to better performance and low ones to worse, both examples of self-fulfilling prophecy. The proposed mechanism is that students internalise the labels they receive and act accordingly. The effect is often cited in discussions of education and social class. However, it remains controversial, because researchers have repeatedly failed to replicate the original strong, statistically significant result.
The Pygmalion effect is a key idea behind the claim that expectations can change outcomes in classrooms and workplaces. The debate over whether it holds up shows why replication matters in psychology.
Pygmalion is named after a myth in which a sculptor's statue comes to life after he falls in love with it.
