Motivated forgetting is a debated concept referring to a psychological defence mechanism in which people forget unwanted memories, either consciously or unconsciously. There are times when memories are reminders of unpleasant experiences that make people angry, sad, anxious, ashamed or afraid. Motivated forgetting is a method in which people protect themselves by blocking the recall of these anxiety-arousing memories. For example, if something reminds a person of an unpleasant event, his or her mind may steer towards unrelated topics. This could induce forgetting without being generated by an intention to forget, making it a motivated action. There are two main classes of motivated forgetting: repression is an unconscious act, while suppression a conscious form of excluding thoughts and memories from awareness.
