Have ever had a really bad day at work and then gone home and taken out your frustration on family and friends? Then you have experienced the ego defense mechanism of displacement. Displacement involves taking out our frustrations, feelings and impulses on people or objects that are less threatening. Displaced aggression is a common example of this defense mechanism. Rather than express our anger in ways that could lead to negative consequences (like arguing with our boss), we instead express our anger towards a person or object that poses no threat (such as our spouse, children or pets).
