The Pygmalion effect is the phenomenon whereby higher expectations lead to higher performance. It can be best understood by a circle where our beliefs about another person’s abilities influence our action toward the other person. This action has an impact on the other’s beliefs about themselves. The believe about themselves cause the others action towards us, which again reinforce our beliefs about that person.
Your beliefs influence your actions.
The Pygmalion effect is also known as the Rosenthal experiment named after a research of Robert Rosenthal at Harvard.
Robert Rosenthal concluded: “When we expect certain behaviors of others we are likely to act in ways that make the expected behavior more likely to occur.”
