According to Sigmund Freud, human personality is complex and has more than a single component. In his famous psychoanalytic theory, Freud states that personality is composed of three elements known as the id, the ego, and the superego. These elements work together to create complex human behaviors.
The id is driven by the pleasure principle, which strives for immediate gratification of all desires, wants, and needs.1 If these needs are not satisfied immediately, the result is a state anxiety or tension. For example, an increase in hunger or thirst should produce an immediate attempt to eat or drink.
The ego operates based on the reality principle, which strives to satisfy the id's desires in realistic and socially appropriate ways. The reality principle weighs the costs and benefits of an action before deciding to act upon or abandon impulses.
The superego tries to perfect and civilize our behavior. It works to suppress all unacceptable urges of the id and struggles to make the ego act upon idealistic standards rather that upon realistic principles. The superego is present in the conscious, preconscious, and unconscious.
