Answer:
Scapegoat theory
Step-by-step explanation:
Scapegoat theory: In psychology, the theory of scapegoat is defined as the propensity of an individual to blame the other person for his or her own mistakes or problems.
The process of scapegoat often leads to develop a feeling of prejudice in an individual towards the other group or person that he or she is blaming.
A person uses scapegoating as a psychological defense mechanism of denial by protruding specific responsibility and blame others.
