Projection
A projection is a perceptual error in which one attributes one’s own perceptions, feelings, or characteristics to another. When individuals unconsciously project their internal experiences onto external stimuli, such as people, objects, or situations, it is called projection. As opposed to the external stimuli, projected attributes may not exist in reality, but rather they reflect the beliefs, desires, and fears of the individual.
It is possible for a person to project anger onto others, assuming those around them are angry or hostile, based on their emotions, motivations, beliefs, and perceptions. In the same way, someone who is dishonest may assume that others are dishonest and deceive as well, projecting their own tendency to deceive others.
