A corollary of the Pygmalion effect is the golem effect, in which low expectations lead to a decrease in performance. The Pygmalion effect and the golem effect are forms of self-fulfilling prophecy. People will take the belief they have of themselves (negative in this case) and attribute traits of the belief with themselves and their work. This will lead them to perform closer to these expectations that they set for themselves. Within sociology, the effect is often cited with regard to education and social class.

Rosenthal posited that biased expectancies could essentially affect reality and create self-fulfilling prophecies as a result.
James Rhem, executive editor for the online National Teaching and Learning Forum, commented:
"When teachers expect students to do well and show intellectual growth, they do; when teachers do not have such expectations, performance and growth are not so encouraged and may in fact be discouraged in a variety of ways." "How we believe the world is and what we honestly think it can become have powerful effects on how things will turn out."
