There is a tendency for people to rise to the level of performance that others expect of them. Closely linked to the concept of self-fulfilling prophecy.
This concept is named after a Greek myth. Pygmalion, a talented sculptor, falls in love with his own creation, the statue of a woman. After Pygmalion falls deeply in love, the statue eventually turns into a real woman.
