An inferiority complex, in the fields of psychology and psychoanalysis, is a feeling that one is inferior to others in some way. Such feelings can arise from an imagined or actual inferiority in the afflicted person. It is often subconscious, and is thought to drive afflicted individuals to overcompensate, resulting either in spectacular achievement or extreme schizotypal behavior, or both. Unlike a normal feeling of inferiority, which can act as an incentive for achievement (or promote discouragement), an inferiority complex is an advanced state of discouragement, often embedding itself into one's lifestyle, and sometimes resulting in a retreat from difficulties.
Mike Lantry, 1972
