The Pygmalion effect, or Rosenthal effect, is the phenomenon whereby others’ expectations of a target person affect the target person’s performance.[1] The effect is named after the Greek myth of Pygmalion, a sculptor who fell in love with a statue he had carved, or alternately, after the psychologist Robert Rosenthal. Rosenthal and Lenore Jacobson, in their book, applied the idea to teachers’ expectations of their students affecting the student’s performance, a view that has been undermined by subsequent research (e.g., Raudenbush [1984]).[2]

Robert Rosenthal and Lenore Jacobson‘s study showed that, if teachers were led to expect enhanced performance from children, then the children’s performance was enhanced.

Rosenthal argued that biased expectancies could affect reality and create self-fulfilling prophecies.[4]
