Answer:
Self-fulfilling prophecy
Explanation:
The term self-fulfilling prophecy was first coined by Robert Merton to explain that when a false definition is given to a situation or painted in another way that is not real, behaviors can be invoked, making such false narrative or false definition come to reality. For example, if one starts the day with negative thoughts or expectation that they would have a bad day, such can affect the individual’s behavior in a way that causes such expectation to come to reality.
