The fading affect bias, more commonly known as FAB, is a psychological phenomenon in which memories associated with negative emotions tend to be forgotten more quickly than those associated with positive emotions.[1] FAB only refers to the feelings one has associated with the memories and not the content of the memories themselves.[2] Early research studied FAB retrospectively, or through personal reflection, which brought about some criticism because retrospective analysis can be affected by subjective retrospective biases. However, new research using non-retrospective recall studies have found evidence for FAB,[1] and the phenomenon has become largely accepted.
