What is Inner critic?

The inner critic or "critical inner voice" is a concept used in popular psychology and psychotherapy to refer to a subpersonality that judges and demeans a person.

A concept similar in many ways to the Freudian superego as inhibiting censor, or the negative Jungian animus, the inner critic is usually experienced as an inner voice attacking a person, saying that they are bad, wrong, inadequate, worthless, guilty, and so on.
