Projection (from the Latin procere, "to throw forth") is psychological defense mechanism by which an individual unconsciously transfers his or her feelings to another person. Surprisingly, this unconscious transfer may be not only of negative attributes, but positive ones as well. Projection is classified as as defense mechanism, as it is a means by which the individual avoids having to process his or her own feelings. In the extreme, projection can transform into paranoid delusions, as the individual believes that others are responsible for the feelings the individual experiences.

Projection usually takes one's unacceptable qualities or feelings and projects them onto others. It is a defense mechanism and works by expressing those negative or impulsive feelings, but in a way that the conscious does not recognize, therefore reducing anxiety in a person.
Projection is one of the defense mechanisms. It is by which people disguise their own threatening impulses by attributing them to others.
