Prophecy.
Explanation:
Self-fulfilling prophecy is a socio-psychological phenomenon of someone predicting or expecting something, positive or negative, and this prediction (prophecy) or expectation comes true simply because one believes it will, and their resulting behaviors align to fulfill those beliefs, including the act of predicting it (self-fulfilling).
