In 1948, American sociologist Robert Merton developed the concept of the Self-Fulfilling Prophecy.
The theory says that a prediction or expectation can become true if a person’s belief in it influences their behaviour, which can lead to the fulfillment of the prophecy.
In the article, Merton defines it as:
“[The Self-fulfilling prophecy] is a belief or expectation, correct or incorrect, could bring about a desired or expected outcome.”
For example, if you’re a teacher and you constantly call a student a bad student, the chances of him becoming a bad student for the long run will increase because he’ll start to believe it.
Additionally, this can extend to groups of people as well.
