In other words, causing something to happen by believing it will come true
An employer sees a new employee and automatically expects him to be disloyal. The employer then treats the employee in a way to elicit the very response he concluded.
Labeling someone a "criminal," and treating that person as such, may foster criminal behavior in the person who is subjected to the expectation, thus creating a self fulfilling prophecy
Self-fulfilling prophecy is the reason that many blacks, NOT ALL but many, are criminals.....because of the way they brought themselves up. Self-fulfilling prophecies are especially quite common with Generation Y.
