Defense Mechanism

Circumstances influence and compel people to behave in a certain way. One such behavior is a defense mechanism. It is employed by people to escape from unpleasant circumstances, thoughts and actions. Defense mechanisms are, thus, psychological strategies that help to avert and avoid unwanted feelings such as guilt or shame and situations such as threat and danger.
