Patterns of human self-defeating or self-destructive behavior are examined in relation to several hypothesized causes. Threatened egotism appears to be a major, pervasive cause: Self-defeating responses are especially common when people feel that others may perceive them less favorably than the people desire. Self-regulation failure is also a common element in most self-defeating behavior. Emotional distress is often a precipitating factor. Several causal processes, including foolish risk taking and escapist responses, link emotional distress to self-defeat.
