Self Fulfilling Prophecy

____

Example 1:
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.

Example 2:
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
